Back to the Cast for Girl Genius Volume Seven
Main Characters
Our favorites!
Key Concept: The Spark
The mysterious quality that makes Mad Scientists what they are. Also used as another term for a Mad Scientist— so you would say that someone is a Spark if they have the Spark. 
Agatha Clay / Agatha Heterodyne
The Girl Genius of the title, Agatha was recently revealed to the world as the last of the heroic Heterodyne family. Agatha is only now coming to realize her full potential as a Spark, and is finding that both her talent and her family make her a target in the eyes of the powerful. Because of some unfortunate events in a recent adventure, Agatha is currently sharing her mind with that of an evil mad scientist/goddess queen, (even more embarrassing, it's also her mom) and must wear an amulet to suppress the invader.

She is now in Mechanicsburg, in the process of taking back the family castle.

Baron Klaus Wulfenbach
Probably the most powerful Spark around. Rules a large part of Europe from his vast airship Castle Wulfenbach. Even though he traveled with the Heterodyne Boys in his younger days, and therefore has some claim to "hero" cred, he is now considered a despot. He's the first to admit that he is a despot, but he doesn't enjoy it. The Baron tried his best to capture Agatha because he believes her to be The Other, a malevolent Spark who almost destroyed Europe nineteen years ago. This idea was bolstered when Agatha, who was being possessed by The Other at the time, infected Klaus with a new form of slaver wasp, unleashed monsters upon the city of Sturmhalten, beat back his army, and dropped a chicken house on him. (Actually, Agatha wasn't possessed when she dropped the chicken house on the Baron, that was all her own doing. But he'd got her mad.) He is currently recuperating at the Great Hospital in Mechanicsburg.
Gilgamesh Wulfenbach
The Baron's son and heir presumptive to the Wulfenbach Empire, Gil was raised in secret and only recently revealed to the World at large. Said World is less than thrilled. Gil would very much like to marry Agatha, and, as a top-notch Spark himself, has a reasonable chance of keeping up with her. Unfortunately, his father is dead set against it, what with the whole "possibly crazed person responsible for the last twenty years of war and assorted atrocities" thing. Gil wants nothing more than to find Agatha and sort all this out, and he might soon get his wish.
Krosp I--Emperor of all Cats
A failed experiment designed to rule over all Catkind. Sadly, Cats are too ineffective to be good for much. Krosp escaped from Castle Wulfenbach with Agatha and considers her his first and only subject, even though she isn't technically a cat. Krosp is the cynical voice of reason and practicality, and thus is usually ignored.
Zeetha, Daughter of Chump
A Princess of the Lost City of Skifander, Zeetha doesn't remember how she got to Europe, so she's lost as well. She met Agatha while performing martial-arts tricks with Master Payne's Circus. Agatha was the first person who'd even heard of Skifander, in a story told by her uncle, Barry Heterodyne. Zeetha has now joined Agatha, with the idea of helping find Barry. She has also taken Agatha on as 'Kolee-dok-zumil', and is teaching her self defense, martial arts, and how to act like a princess. (It apparently involves swords and rescuing princes and such.)

Zeetha may or may not have been sent by an as-yet unspecified person to kill Gilgamesh Wulfenbach, for as-yet unspecified reasons.
Ardsley Wooster
Every British citizen is required to travel and see a bit of the world. Wooster met Gilgamesh when they were both students in Paris. Gil had yet to be revealed as the Baron's son, and the two hit it off and spent many a jovial evening in the City of Light. Wooster asked if Gil could secure him a position as a manservant aboard Castle Wulfenbach. Gil did so, and Wooster was astonished to discover that his new master was actually the here-to-for unknown heir to the Baron. The two worked well together until Gil revealed that he had been aware all along that Wooster was actually a secret agent for British Intelligence. He has been sent to protect Agatha and convey her to England to keep her safe from the Baron. Unfortunately for Wooster, Agatha has a mind of her own and she went to Mechanicsburg instead. Wooster doesn't even want to imagine what will happen if she gets hurt on his watch.
Bangladesh DuPree
Our favorite bloodthirsty maniac. A dethroned pirate queen currently working for Baron Wulfenbach.
Dingbot Prime
Agatha's first Dingbot. It is a small, autonomous clank. Capable of semi-independent thought, it manages to follow Agatha throughout the story, which has come in handy on occasion. Whenever it has a free moment, it starts constructing other dingbots, which proceed to build other dingbots, and so on. These swarms quickly become capable of performing alarming feats of engineering. Fortunately, subsequent generations tend to wear out quickly.
The Flashback Characters and their Fictional Counterparts
Heterodyne Shows
The Heterodynes aren't really around anymore, but they still have a big impact. Heterodyne Shows are popular commedia-style stage plays featuring well-known adventures of the Heterodyne Boys and other popular folk heroes. Shows of this type can be found all over Europe. Although some of them may have roots in actual historical events, most are simply entertainments created and added to by innumerable theatre troops for the entertainment of a public which has no interest in anything so boring as facts.
  Bill and Barry: The Heterodyne Boys
A generation Bill and Barry Heterodyne renounce their family's tradition of evil, and traveled the World righting wrongs, helping the helpless, and having fantastic adventures. They gathered together a group of like-minded individuals and changed the face of Europe. But after Bill's wife Lucrezia was kidnapped and his son killed in a mysterious attack on Castle Heterodyne, they began a long war with the mysterious Other, which culminated in their disappearance. The peace they worked for fell into ruin, paving the way for the far less patient Baron Wulfenbach. Today, close to twenty years later, they are still great favorites in song and story. Many say that they will someday return, bringing about the fall of Wulfenbach and free beer for all.
The Evil Dr. Mongfish (later reformed)
A frequent opponent of the Heterodyne Boys in the early days. Later reformed when, after a series of exciting adventures, his daughter Lucrezia married Bill Heterodyne. Died in an attack on Castle Heterodyne.
Lucrezia Mongfish
The Beautiful Daughter of one of the Heterodyne Boys most persistent foes, Lucifer Mongfish. She is/was worshipped as a Goddess (for reasons that her family always found a bit confusing) by a lost civilization of ghost-white amazons living near her father's secret base/summer home. After a series of futile clashes with the Heterodynes, she eventually married Bill and joined the Forces of Good. This lasted until Castle Heterodyne was attacked while the Heterodyne Boys were off on a mission. That was the last anyone in Europe ever heard of Lucrezia, and she was presumed to have been kidnapped by the mysterious person who came to be known as "the Other." In reality, as Agtha has recently discovered, Lucrezia herself is the Other. Her purposes are, as yet, unexplained.
The Other
Big Nasty Mysterious Spark of unknown origin. Made a real mess of Europe before the Heterodynes went off to put a stop the whole business. They must have succeeded, because the Other's attacks stopped right around the time they disappeared. That's all most people know. Recently, Agatha has discovered that the Other was actually her own Mother, (Lucrezia Mongfish) backed by Geisterdamen priestesses and an as-yet unnamed order of knights that she apparently subverted for her own purposes.
  The High Priestess
A stock character in the Heterodyne stories. Not played as a consistent character, "The High Priestess" can be written as the queen or priestess of whatever lost city to which the adventure takes the heroes, or, more rarely, simply as the latest villain's beautiful-but-misguided assistant. The character of Bill always winds up with Lucrezia, and Barry always ends up with "the High Priestess," whomever she may be this week. Most stories favor exotic characterizations and attire for this role.
Young Agatha
Uncle Barry
Barry Heterodyne, as Agatha remembers him from when she was very young.
The Jägermonsters
Enthusiastic construct soldiers created in the days when the Heterodyne ancestors were somewhat less than heroic. They are tough, crazed and possibly immortal. In the absence of their original masters, they have hired on as mercenaries to the Baron, but never gave up hope that the Heterodynes would return.
   Oggie, Dimo & Maxim
When the Jägermonsters signed on with the House of Wulfenbach, a amall number of them were sent out into the world to search for the Heterodynes: forever, if need be. These Jägers do not work for Wulfenbach, and are considered "wild" Jägers. Oggie, Dimo & Maxim are some of these, and are the ones who actually found Agatha. They are very proud of themselvves, and have been protecting her ever since. They are all amazing fighters, and unsettlingly smarter than they look; but then they'd have to be, wouldn't they?
Ognian "Oggie"
One of a group of "wild" Jagermonsters who travel the wastelands searching for an heir to the Heterodyne family. Oggie is the most care-free of the group. He still keeps track of his Mechanicsburg descendants, and nags them about continuing the family line.
One of a group of "wild" Jägermonsters who travel the wastelands searching for an heir to the Heterodyne family. Dimo is the oldest, and arguably the smartest of the three. He is the one who usually comes up with "the plan." He is as world-weary as a Jäger can get, which isn't saying much.
One of a group of "wild" Jagermonsters who travel the wastelands searching for an heir to the Heterodyne family. An ex-cavalry officer, Maxim is the most resigned of the group.
Jenka and Füst
Jenka is one of a group of "wild" Jagermonsters who travel the wastelands searching for an heir to the Heterodyne family. Now that her little band has found Agatha, Jenka has gone off to report to some unknown person, and set Ognian, Maxim and Dimo to keep Agatha alive. Füst is Jenka's bear.
Captain Vole
A Jäger who is considered (by all the Jägers including himself) an Ex-Jägermonster. Most non-Jägers are puzzled by this assertion, but it works for them. So, Vole was thrown out of the club, for reasons that are as yet unclear. While the rest of the Jägers are forbidden to enter Mechanicsburg until a new Heterodyne returns, he has been confined there for the last fifteen years. He has a great deal of hate for the Heterodynes, and tried to kill Agatha.
Jäger General Zog
One of the oldest living Jägermonsters. A little smarter and more grounded than the average Jäger. Are those furry pants?
Jäger General Goomblast
One of the oldest living Jägermonsters. A little smarter and more grounded than the average Jäger. Did he start out human?
Jäger General Khrizhan
One of the oldest living Jägermonsters. A little smarter and more grounded than the average Jäger. Maybe also a little smarter and more grounded than his fellow generals.
Transylvania Polygnostic University and Beetleburg
Translyvania Polygnostic University
One of Europe's oldest and most respected centers of learning, and the place Agatha has been wandering around since she was a kid. TPU is surrounded by the town of Beetleburg.
  Adam and Lilith Clay
Frankenstein-type constructs who raised Agatha from the time she was small. Later revealed to be "Punch and Judy;" the Heterodyne Boy's famous construct servants. (Always portrayed as comic-relief in the popular Heterodyne plays, much to their annoyance.) Died getting Agatha off the Castle Wulfenbach airship. Agatha doesn't know it yet, but they have since been revived by Gilgamesh. And he's made some improvements.
Doctor Tarsus Beetle
The tyrant of Beetleburg and the administrator of Transylvania Polygnostic University. One of Klaus Wulfenbach's teachers. One of the few people who knew that Barry Heterodyne returned, knew the true identity of Adam & Lilith Clay, and the true identity of Agatha, as well as the importance of her locket. When he was caught researching forbidden technology, he attempted to capture the Baron, and was blown up by one of his own bombs, a incident that everyone deplores. DECEASED
Mr. Tock
TPU's beloved-but-slow guardian and clock tower. Severely damaged in the recent fight with the Baron.
The Watch
Small versions of TPU's Mr. Tock. They patrol the campus and town of Beetleburg.
Dr. Hugo Glassvitch
Agatha's favorite teacher. He's kind to her even though she's a spaz.
Dr. Silas Merlot
Agatha's least favorite teacher. Merlot has issues of his own, and Agatha drives him crazy. Dr. Merlot is now a prisoner in Castle Heterodyne. What did he do to land himself there?
  Moloch VonZinzer
Moloch and Agatha got off to a rocky start when Moloch's brother stole Agatha's locket; and died of it. Agatha and Moloch were captured and taken aboard Castle Wulfenbach, where Moloch was assumed to be the Spark who built the Beetleburg Clank. Actually, Agatha built the clank, a fact that the Baron's son and Moloch attempted to hide from the Baron. Moloch has just resurfaced as a prisoner in Castle Heterodyne, where he and Agatha have finally come to terms with each other. Moloch insists that he is "no-one's happy little helper," all the while carrying the luggage.
The Hive Engine
A large machine which produces slaver wasps, biological mind-control instruments used by the Other. Particularly nasty and dangerous if one is allowed to activate inside a town. Slaver wasps turn people into Revenants, unable to avoid following direct commands by the Other.
The Goldfish
It's just a goldfish. Really!
The Doctor in Beetleburg
The doctor who treats Omar vonZinzer in Beetleburg.
Castle Wulfenbach and the Baron's Staff
Boris is the Baron's four-armed secretary. Boris is brilliant, loyal and completely humorless. He doesn't get along well with the Jägers, but they LOVE him. (To pick on.)
A scary construct apparently connected in some way with Lucrezia Mongfish (later Heterodyne.) VonPinn is the guardian of the children aboard Castle Wulfenbach. She is trained as a teacher and governess, and had no small hand in the rearing of young Gilgamesh Wulfenbach, which explains a lot.
A strange little crab/insect/whatever construct that Gilgamesh Wulfenbach built when he was a small child. Still employed in Gil's lab, where it makes the tea. It's afraid of the goldfish.
Dr. Vg
Not a Spark, but a brilliant, methodical scientist. Was the Baron's chief assistant while studying the captured slaver engine.
Mr. Rovainen
Not a Spark, but a reliable and useful assistant. Right up until he killed Dr. Vg, of course... Sometimes honorarily referred to as "Dr." He did all the work, then his university was destroyed right before commencement. This is a sore spot with him.
The Lackya
"Super-engineered squirrels, or something." The lackya are a group of construct servants created by the Gilded Duke. After their master's fortress was destroyed, they came to work for Klaus. They don't get along with the Jägers.
Dr. Dimitri Vapnoople (Dr. Dim)
The Spark who created Krosp. Now not so Sparky, apparently due to the Baron's experiments. There may be more to this story than meets the eye... Was Krosp created before, after, or during Vapnoople's mental decline?
Wulfenbach Troops
Wulfenbach Clanks
Soldier clanks built by Baron Wulfenbach. Some of the best in the World.
The Unstoppable Higgs
Machinist Mate third Class Higgs has quietly served aboard various Wulfenbach airships for ten years without distinction. Recently he survived a airship crash and succeeded in rescuing the Baron while he was at it. Everyone was very impressed. Recently, Higgs met Gil in Mamma Gkika's and has now been assigned to carrying Gil's Fabulous Hat. (A gaudy, but heartfelt, gift from the Jägers.)
Wasp Hunters
A division of Wulfenbach's troops that specializes in dealing with slaver wasps, hive engines, revenants and infected towns.
Wasp-Hunting Weasel-Like Critters
A very recent development. These little creatures can sniff out slaver wasps and also detect those who have been infected by the wasps. It is largely due to the creation of these beasties that the Baron now knows that revenants (people under the control of the Other) are not always necessarily shambling zombie things. This came as rather a surprise.
Sergeant Scorp
An old soldier. One of the Wulfenbach soldiers who specializes in dealing with slaver wasps and revenants. Scorp is one of the few Wulfenbach soldiers who got a good look at Agatha back in Sturmhalten, and is now in Mechanicsburg helping search for her.
The Black Squad
Wulfenbach troops who appear to have some sort of spacial-displacement ability. Not to be tangled with...usually.

The Castle Wufenbach Students

Theopholous duMedd
A Spark and storyteller. Theo is the son of the oldest daughter of Dr. Mongfish, and is therefore Agatha's cousin. He was orphaned at an early age, and was taken in by Baron Wulfenbach. He was raised aboard the Castle Wulfenbach airship and was a good friend to Gilgamesh Wulfenbach before Gil left for school in Paris. Theo left the Castle in secret during the chaos of Agatha's escape. His current whereabouts are unknown.
Her Highness Zulenna Luzhakna, Princess of Holfung-Borzoi. A rather good swordswoman. Most of Europa's noble families have become extinct, dwindled in power or kept hold by marrying into the Great Houses of the Sparks. Zulenna's family is one whose power is waning, but able to hold on due to help from the Heterodynes. She's extremely touchy about rank, and not at all nice, but she has her own code of honor, and she pays her debts.
Sleipnir O'Hara
Sleipnir's father is a ruling Spark in the region of Wulfenbach's Europa informally termed "Little Ireland." She is one of the students who really IS on Castle Wulfenbach as a hostage against her family's good behavior.
Nickodaemus Yurkofsky
A tall, gentle boy whom the baron suspects will eventually break through as a Spark. Not much to say about him right now, he's just one of the nicer students on Castle Wulfenbach.
Has a huge long name that his friends mostly don't bother with. Z is a younger son of the famous Iron Sheik. He is justifiably proud of his father, who is a major Spark and an old friend of the Heterodyne Boys and the Baron. The Iron Sheik's lands are not within Wulfenbach's Europa, Z is a student on Castle Wulfenbach because his father thought it would be a good experience for him.
Hezekiah Donowitz
Another of the Wulfenbach students. His father is a strong Spark.
Sun Mingmei
The grand-daughter of Dr. Sun. Her parents are noted adventurers whose current location is unknown. Mingmei was, until recently, being educated on Castle Wulfenbach.
Itto Wheelwright
The son of two very powerful sparks. Itto is already brilliant beyond his years and considered almost certain to break through as a Spark someday.
The Kid with the Clock in his Forehead
One of the students on Castle Wulfenbach.
The Circus
Master Payne's Circus of Adventure!
The Circus' big attraction is their Heterodyne Show-- popular commedia-style stage plays featuring well-known adventures. Shows of this type can be found all over Europe.
Master Payne
Of the International Brotherhood of Evil Magicians. A showman and minor Spark, his traveling Heterodyne Show travels the wastelands, entertaining, scavenging, and rescuing other minor Sparks from their home towns. It's his circus, and what he says, goes. Currently the show is embarking upon an extended tour of England.
Countess Marie
Royalty is not what it's cracked up to be, so she ran away to join the Circus and married the Circus Master. The perfect Yin to Master Payne's Yang, they run the circus like an extended family and don't you forget it. A mad chemist, among other things.
The advance-man for the circus. Surprising, since Lars was a Great Big Chicken, but it made him sensitive to danger and resourceful in avoiding it. The perfect person to send ahead to check out the next town on the route. In the Heterodyne Shows, Lars played Bill Heterodyne. He was the one who did the most to draw Agatha out of her shell and, a bit of a rake, he was astonished to find himself falling for her, so much so that he led a rescue party to find her when she was captured by Prince Aaronev. These feelings cost him his life when he saved Agatha from being killed by an enraged Baron Wulfenbach. DECEASED
Master Payne's right hand man. Has recently become involved in a romance with Pix.
Pix was instrumental in convincing the Wulfenbach search party that Agatha was dead. Due to that adventure, Pix has recently become romantically involved with Abner, the Circus Masters' second-in-command.

Pix usually ends up playing Lucrezia Mongfish in the Heterodyne shows, which annoys her. She has always wanted to play "The High Priestess." For a while, she got to, as she was able to fob the Lucrezia role off on Agatha.
The circus' music master and a very minor spark who works mostly with sound waves. André plays Barry in the Circus' Heterodyne plays.
Dame Aedith
Dame Aedith is a vampire hunter. Despite the fact that there is absolutely no empirical evidence for the existence of vampires, she has managed to find and destroy several. Sadly, Aedith's methods never leave enough material for scientific study, but she feels her word as an "Agent of the Forces of Good" should be enough to convince anyone. Aedith is dedicated to her calling, but is currently traveling with Master Payne's circus for mysterious reasons of her own. She is quite mad.
A little kid who first befriended Agatha and brought her to the Circus. Spins plates and juggles. His daddy plays the character of "Punch" a lot in the circus' stage plays, and may be a minor spark.
Balthazar's Daddy
Balthazar's Daddy often plays the character of "Punch" (One of the Heterodyne Boy's comic-relief monsters) in the circus' stage plays. He was once a smith who worked for The Gilded Duke until the Duke was defeated by Baron Wulfenbach's forces. How much involvement he had in the creation of the clank called "Smilin' Stev" is unknown.
The Circus Chef
Revels in frequent roles as "Klaus, the Heterodyne Boys' Cowardly Sidekick." Is convinced that there is no problem that cannot be solved by some form of pie.
An explorer from Africa who travels Europe searching for exotic adventure. Embi is a Pygmy, and so, although he is proficient in storytelling, juggling and many other forms of entertainment, his main attraction for the crowds is that he is short.
Professor Moonsock
The circus' animal trainer. A minor Spark.
One of the Circus' mechanics. Ollie frequently plays the comic drag role of "Judy" (one of the Heterodyne Boys' monster sidekicks) in stage shows.
Small and strong and keeps everything running. Rivet is a slightly sparky toolmaker and a fantastic mechanic. She loves her tools and machines and is impatient with silly people, so she has trouble communicating. Onstage she's completely the opposite, always an audience favorite.
Thundering Engine Woman (Circus Version)
The REAL Thundering Engine Woman was an extremely powerful American Spark who adventured with the Heterodyne Boys for a brief period. She was received in most of the courts of Europe, was highly regarded by the general population, and set off a long-running fad for things American. So it's no wonder that actors impersonating her occasionally show up with traveling shows.

The Thundering Engine Woman of Master Payne's Circus of Adventure is actually a nice Italian girl whose grandfather traveled extensively in the Americas. Like all the actors in the troupe, she fills many roles, but she especially shines at sharp-shooting and being excitingly "foreign."
Yeti can lift heavy things, and is a minor Spark. Was Zeetha's boyfriend for a while, but they parted ways when the Circus left for England and Zeetha stayed behind with Agatha.
The Town of Sturmhalten
The Muses
Were a set of clanks built by the master Spark artificer, van Rijn for the Storm King. There were nine of them and each had a specialty. After the fall of the Storm King, they Muses were scattered and presumed lost. Today they are considered legends, and many Heterodyne Shows and other traveling mountebanks have a "Muse" as part of the show to awe the credulous. They also feature as characters in the second act of Portentius Reichenbach's opera The Storm King, echoing the Spirit of Europa's prophecy that peace will only come when the Heterodyne Princess and the Storm King are wed.
A game-playing automata, and one of van Rijn's lost Muses. Discovered by Master Payne and for several years a part of his show. Moxana seems to be able to see larger patterns in the world, and thus has a reputation for being able to foretell the future. In Sturmhalten, she left the circus to join Prince Tarvek, the current Storm King apparent.
One of van Rijn's lost Muses. Discovered by Master Payne and for several years a part of his show. Tinka is able to read "body language" to an uncanny degree. In addition, she is able to reflect this back, by way of dance, and thus can alter the mood of an entire audience. Was confiscated and damaged by the Sturmvoraus family.
The Town of Mechanicsburg
The Ancestral Hometown of the Heterodyne Family. One can say many, many, many derogatory things about the state of the Heterodyne family's sanity, but, first and foremost, they were cunning. The townspeople were, as they say, "In on the take." While the Heterodynes rampaged over the land, the folks back home were left reasonably unmolested. In return for their loyalty, they served as minions, guards, troops and fencers of stolen goods; as opposed to everyone else, who served as experimental subjects, victims, sources of wealth and decoration. Under the Heterodyne Boys, the town changed its modus operandi, but not its underlying purpose. Today Mechanicsburg is a magnificently-crafted machine designed to separate tourists and the gullible from their money. It is also the center of several thriving black markets and smuggling operations. Still, many of the older people fondly remember the Glory Days, when "Made in Mechanicsburg" brought terror to the world at large.
Keeps von Mekkhan's house, and brings home rumors from the marketplace. Is she his daughter-in-law, grand-daughter or something else? It has yet to be explained.
Carson von Mekkahn
(alias: Carson Heliotrope)

The retired seneschal of Castle Heterodyne. He knows all the secrets of the Castle and the town, and was the voice of the Heterodyne family to the general populace. After the Other's initial attack, he faked his death and allowed The Baron to believe that the family had gone extinct. He continues to pull Mechanicsburg's strings from the shadows.
Vanamonde von Mekkahn
(alias: Vanamonde Heliotrope)

Carson's grandson. Ostensibly the current seneschal, though he obviously has not been confirmed either by a Heterodyne or by the Castle. He has a different management style than his grandfather, preferring to let people come to him, rather than visa-versa. Old-timers might grouse about the touristy claptrap, but Mechanicsburg has never been more profitable.
Castle Heterodyne
The home of the Heterodynes. Several hundred years ago, Faustus Heterodyne modified it, turning it into a gigantic, self regulating A.I. It's been broken for years, but the stories say that when new it could repair itself, re-arrange itself, and defend itself and possibly even the town. It has the personality of old Faustus, who was an evil, bloodthirsty, megalomaniacal schemer. It is insanely loyal to the Heterodyne family, and it spends a great deal of time and effort making sure that there will be another generation of Heterodynes to carry on the trouble. Young Heterodynes learn very quickly not to bring home dates.

Castle Heterodyne was damaged years ago, and is currently not functioning properly. Part of the Castle has acknowledged Agatha as the ruling Heterodyne, but many other areas are still dangerous territory for her.
Faustus Heterodyne
One of the old Heterodynes, which means a dangerous madman of the first water. Faustus was responsible for "awakening" Castle Heterodyne, endowing it with his own charming personality. HISTORICAL
Zola "Heterodyne"
A young woman who claims to be the Heterodyne girl who beat Baron Wulfenbach. (Of course, we all know she's not, that was Agatha...) She has backers who have yet to reveal their agenda.
Zola's Minions
A bunch of guys in funny hats who appear to be along to carry the equipment and get killed.
Duke Strinbeck
One of the people behind the false Heterodyne. Currently learning to fly after threatening to shoot the captain of his airship.
Baron Oublenmach
One of the people behind the false Heterodyne. Currently lurking above the city in a pink airship.
Un-named Airship Captain
Captain of the ship currently hovering over Mechanicsburg. Isn't too thrilled with his current employers, job, or ship.
Wheelman of the ship currently hovering over Mechanicsburg. An old airshipman who knows enough to be nervous about flying over Mechanicsburg.
Agatha's new secretary, although Agatha doesn't yet know it.
Wilhelm Diamant
The outside man in charge of the Castle Heterodyne prisoners. He transports and supplies them and reports to the Baron.
The Great Hospital at Mechanicsburg
Dr. Sun Jen-djieh
The Spark in charge of the Great Hospital of Mechanicsburg. A friend and traveling companion of Baron Wulfenbach in his youth, and one of the few people who feels free to contradict Klaus on a wide variety of subjects. He rules the Hospital with an iron hand, and aside from a tendency to indulge in unorthodox experiments (which usually yield surprisingly beneficial results), has made it a model of efficiency, hygiene and advanced medicine. Until recently, his grand-daughter was being educated on Castle Wulfenbach.
The Coffee House in Mechanicsburg
Café Waitress 01
Serves coffee in Van's Café.
Café Waitress 02
Serves coffee in Van's Café.
Café Waitress 03
Serves coffee in Van's Café.
Herr Mitrant
A master artificer who was in the Café trying to fix the coffee maker when Agatha happened to it. One of the first to take to Agatha as the new Heterodyne.
The Graverobber Kid
His (her?) family has served the Heterodynes for a hundred years. Wanting to get in on the act, this one has brought Agatha a dead rat, because that's all he (she?) could find. A loyal minion, indeed!
Inside Castle Heterodyne
Professor Hristo Tiktoffen
A senior prisoner within Castle Heterodyne. He is an "old timer," meaning he's been there for longer than three months. In charge of figuring out the layout of the defenses, wiring and such, and also one of the people who keep track of how many points prisoners earn. When someone is sentenced to work in Castle Heterodyne, they are sentenced not in years, but in points. They have to complete X number of points of service in order to be released. Go-getters, while they accumulate points quickly, also tend to take on more dangerous assignments and thus die. Some slackers have survived for years by doing nothing. Hristo is actually part of the conspiracy to install a false Heterodyne.
Sanaa Wilhelm
A prisoner within Castle Heterodyne. Agatha met Wilhelm not long after she entered Castle Heterodyne, and they hit it off well. Wilhelm is currently part of a group of prisoners sent to kill Agatha. Unfortunately, their search has taken them (at the point of Zola's gun) into a dangerous part of Castle Heterodyne.

Moloch is in love with Wilhelm, and acts like a fool in her presence. She thinks he's an idiot.
"Snapper" Boikov
A prisoner within Castle Heterodyne.
Wandering Monsters
Othar Tryggvassen
Gentleman Adventurer and Professional Hero. Thinks of Agatha as his "Spunky Girl Sidekick," but still tried to kill her when he found out she was a Spark. Othar's sworn mission is the destruction of all of the World's Sparks--including, eventually, himself.
The Search Engine
Agatha built this to find the people who stole her locket. Unfortunately, she built it in her sleep. It wound up bringing the Baron straight to Clay Mechanical.
The Geisterdamen
Spooky ghost-white women who ride giant spider-like creatures. Folklore claims they steal children and create Revenants. In reality they are the servants of Lucrezia Mongfish, whom they revere as a Goddess. Brought to Europe by unknown means, they are now trapped here, and for the last eighteen years they have searched for Agatha. Now that they have found her, they have been given an avatar of their goddess, and they have vanished. Their current machinations and location are unknown.
Slaver Wasps
Slaver Wasps were terrifying construct insect-like creatures created by the Other. A person attacked by them found themselves forced to do the bidding of the Other as a Revenant. Whole towns were infected during the Long War. A person who is infected is termed a Revenant or a Mummer.
A person infected by a Slaver Wasp and under the control of the Other. As far as most people know, Revenants are shambling, zombie-like creatures, easy to detect and destroy. Recently it was discovered that only a percentage of those infected showed these symptoms. It turns out that many infected Revenants do not even know that they are infected, and act perfectly normal. They have been undetected by the Baron (or anyone else who wasn't working for the Other) for years, simply awaiting the return of their mistress. They are also known as Mummers.
The Monster Horse-Thing

Some of these are less actual people in the GG universe than characters from stories told within the GG universe.

---short story: The Electric Coffin
One of a group of con-artists, all constructs. He's sort of a hairy little wolfman creature.
One of a group of con-artists, all constructs. She's a big girl, and very strong.
Torsti Lechwa
One of a group of con-artists, all constructs. Bilk the villagers, die, get reanimated, move on. It usually works pretty well!
One of a group of con-artists, all constructs. Zon has madgirl issues.
---short story: The Crown of the Sleeping King
A Trelawney Thorpe Adventure! by Sir Hubert Snappington
(aided by Professors Foglio, Foglio and Wright of TPU.)
Trelawney Thorpe
The heroine of a series of adventure stories from England. Gilgamesh Wulfenbach is a huge fan.
Jolly Jack Tarr
The kind-of-annoying sidekick in the Trelawney Thorpe novels. We've heard that Trelawney is a real person, which we very much doubt, but nobody believes that Jack is for real.
Professor LeMort
A frequent villain in the Trelawney Thorpe novels.
Princess Urania
Currently the most popular of Her Undying Majesty's perpetually-frustrated and often fast-living heirs.
King Arthur Pendragon
England's once and future king.
The Authors

Professors Foglio and Foglio
Of the Transylvania Polygnostic University dept. of Almost Certainly True History. "We make our textbooks fun!"

Both Professors research and write their version of the life of Agatha Heterodyne, entitled Girl Genius. Professor Phil Foglio storyboards the action and draws the pictures. Colors are provided by various assistant professors. Professora Kaja Foglio does all the digital work, such as scanning, lettering, book layout and Web design. Both professors are responsible for hashing out the final scripting between them. The resulting fights are fine examples of high drama, and are spectacular to behold. No, you can't watch.

Professora Foglio provides the voice of Agatha Heterodyne in the University's popular, if dangerous, Girl Genius Radio Theatre productions. Professor Foglio does the voice for Krosp, the Emperor of Cats, Deathwish DuPree, and various others, depending upon how he feels that day.

HI! He's everywhere. All hail.

Girl Genius is written by Professors Phil & Kaja Foglio of TPU, with drawings by Prof. P. Foglio.
Volume One was inked by Brian Snoddy. Volumes Two and Three were colored by Mark McNabb. Volume Four was colored by Laurie E. Smith. Cheyenne Wright is our current colorist. His work begins with Volume Five. Our email and social media assistant is Chris Sorensen.
