Blaise is Doctor Tachyon's grandson. He is a human/Takisian hybrid with very potent mind control powers and a very nasty personality.
Big Bad: In Book 10, Double Solitaire, he instigates the first world war on Takis in thousands of years in an effort to seize complete power.
Body Surf: In the Jumper books he acquires this power, which he uses to transfer his grandfather into the body of a teenage girl.
Mind Control: While he lacks full telepathy, Blaise's mind control powers are extraordinary even by Takisian standards. He can control the Morakh, a Super Soldier breed of Takisian designed to be resistant to mind control.
Pet the Dog: Subverted in Double Solitaire. Blaise claims to be buddies with Jay Ackroyd, a man he used to respect when he was a kid, and then proceeds to cut off his fingers.
Teens Are Monsters: Was raised by a French Communist revolutionary to use his mind control powers to commit acts of terrorism. Tachyon's attempts to provide a better upbringing fall completely flat and Blaise only gets worse with age. By the time he's an adult he's pure evil.
Some Call Me Tim: Tachyon's actual name is Prince Tisianne brant Ts'ara sek Halima sek Ragnar sek Omian of House Ilkazam (and that's just his first name; his full name would list his genealogy for the last thousand generations).
Jube the Walrus
A humanoid walrus that owns a newspaper stand in Jokertown. Everybody likes old, harmless Jube. No one knows that he isn't a joker, or even human. Jube is actually an alien spy, studying Earth for the Network, an alien The Federation.
The main antagonist of the first trilogy of novels, the Astronomer is an insanely powerful Evil Sorcerer that is also the leader of his own dark cult. He is a bad guy's bad guy. Just count the number of "evil" tropes.
Arch-Enemy: The Astronomer and Fortunato both have many enemies, but their own rivalry is extremely bitter, as The Astronomer has killed many of Fortunato's beloved prostitutes, Fortunato has foiled the plans of The Astronomer several times, and both of them are philosophically opposed to each other, with both using sex as the totem of their powers.
Big Bad: The Astronomer is the main villain of the first trilogy of books, and is obsessed with the accumulation of power.
Evil Counterpart: The Astronomer has the same broad array of potent powers — basically anything that is a thematic fit for "magic", as inspired by Eastern mysticism — and charges them by having sex much like Fortunato, but whereas Fortunato sees sex as a spiritual, creative process, The Astronomer rapes and kills his partners and only uses his powers to gain more power.
Evil Cripple: When not super-charged, he is bound to a wheelchair.
Notably, he himself is fully aware of this, and specifically tells another Ace that their powers are the product of Takisian biotechnology. The ritualistic stuff is just a mental exercise to help focus and control his powers.
Religion of Evil: The Astronomer is the leader of the ultra-creepy Egyptian Masons.
Superpower Lottery: Telepathy, telekinesis, flight, phasing, energy blasts, precognition. He can do pratically everything.
A bag lady with the power to communicate with and control animals. Her best friends are two alley cats.
Second Super-Identity: Several. He eventually gives himself the internal identity of "Shad" just so he knows who he is.
Vampiric Draining: He actually creates shadow by absorbing light and heat. He can do it to a person and leave a frozen corpse behind.
Mark Meadows, a hippie with the power to transform himself into several different superheroic alter egos, that he calls his "friends." He is also a genius biochemist. For his various alter-egos, see The Radical, Jumpin' Jack Flash, Moonchild, Cosmic Traveler, Starshine, Aquarius, and Monster.
Modern Major General: Mark spends years as the owner of a head shop in Greenwich Village, but is a piss poor businessman.
Shout-Out: The names of his "friends" are taken from classic rock songs from the 1960s and 1970s.
Super Serum: He has to ingest specially prepared powders to change into his various superhuman forms.
Unlucky Child Hood Friend: Double Subverted. He eventually marries Sunflower, the girl he's loved since forever. But their marriage is not a happy one.
Billy Ray, a Justice Department agent who is stronger, faster, and tougher than a normal human. He also can heal very quick. Carnifex is a ferocious fighter that loves action and mayhem a little too much.
Superheroes Wear Tights: Carnifex is one of few Wild Cards characters who wears a superhero costume. He is a frequent source of ridicule for this, partially because he looks ridiculous in it, and partially because it's sheer white and blood frequently stains it — much to his frustration.
A Cajun girl with the power to shut down a person's respiratory and circulatory systems. She is the niece of Sewer Jack Robicheaux. Works as a young exec for Global Fun & Games.
Demise is James Spector, a failed accountant that was killed by the virus and later came back to life. He gained the power to kill with a look (and he's pretty much unkillable too). Unhinged by his experiences, he became a hitman.
Asexuality: One of the only characters in Wild Cards not interested in sex.
Deadly Gaze: Demise can kill a person by looking into their eyes and telepathically transmitting the memory of the time he drew the Black Queen (the time he was infected by the Wild Card virus and died). Although he has the power to dial it down when he doesn't want the person dead, he tends to use the power very casually.
Pet the Dog: He thinks of himself as a monster (and he is not that far wrong), but Demise hates to kill someone who's been kind to him. And in Ace in the Hole he almost has a Heel-Face Turn after meeting again a heroic school friend.
Required Secondary Powers: A completely invisible person would need some kind of power that let them see, as light that passes through a person's eyeballs is by definition not actually interacting with the photoreceptors, which would be visible otherwise due to reflection or absorption of visible light. Fadeout lacks this secondary power, so he usually leaves his eyeballs visible when he goes invisible.
A half-black, half-Japanese pimp with the power of tantric magic. One of the protagonists in the first trilogy of novels.
Golden Boy is Jack Braun, a WWII veteran and has-been actor with the power of superstrength, invulnerability, and eternal youth. He was a member of the superteam Exotics for Democracy in the 1940s, but has more or less retired from superheroics after being pressured into testifying against his friends in the paranoid political climate of 1950.
Been There, Shaped History: Golden Boy has taken center stage in a lot of 20th century history and rubbed shoulders with a lot of famous people.
The Big Guy: He is often this for any group of aces he's hanging around with.
Black Best Friend: His teammate Black Eagle. Subverted in that Black Eagle is a fully-fleshed out individual who is also more of a true hero than Golden Boy.
Really Gets Around: One of Golden Boy's major character flaws is he's a shameless sex hound.
Reality Ensues: It happens when Golden Boy jumps in front of a escaping automobile and is knocked back a hundred feet. Turns out being invulnerable doesn't mean you're heavy enough to stop a charging vehicle.
A young, mentally disturbed German hunchback with the power to vibrate his own body out of phase with the physical universe. In doing so, he can walk through walls and use his hands as buzzsaw weapons.
Ax-Crazy: Unhinged homicidal maniac that loves to carve people up with his own hands.
Required Secondary Powers: Jerry usually can't change his mass. But he can absorb energy and convert it into additional mass to change into someone bigger. In a later book, he makes explicit use of his energy absorption power to redirect electricity.
A super-sophisticated android created by Mad Scientist Maxim Travnicek. Mod Man is mostly a nice guy, but forced to follow the orders of his sociopathic creator. He fights crime as a superhero as a ploy from Travnicek to gain publicity and wealth.
Three-Laws Compliant: Averted. Travnicek has hardwired imperatives into Modular Man that compel him to obey his creator, but he can fully hurt other people.
Turned Against Their Masters: Travnicek programmed him to be unable of this. Mod Man manages to work his way around it and arranges for Travnicek to be killed anyway. But considering that Travnicek is a sociopath that treats Mod Man as a slave, it's a happy ending.
One of Captain Trips's alter-egos. She is a beautiful Korean woman with superhuman martial arts prowess.
Hypocrite: Gregg views his psychic powers as belonging to a separate entity inside his head; the Puppetman. So that he can still pretend that he's somehow pure as he commits atrocities. His difficulty in acknowledging that he is Puppetman sometimes verges on Selective Obliviousness.
Loveable Rogue: He's this most of the time, but is also a partial Subversion in that Croyd can turn really nasty, almost reaching Ax-Crazy levels when he is on a bad drug trip.
Older than They Look: Croyd regenerates every time he sleeps, so he never grows old. He's active as an ace since the 1940s.
Repower: stays awake for about a month, sleeps for two to three more, wakes up with new powers - and a new appearance - every time. Since there's a very real chance of him waking up dead from this, it's also Superpower Russian Roulette.
Seen It All: He occasionally comes across like this, although given that he's been around since the 1940s, it's not unjustified.
A hideously atrophied joker-ace with the power to possess people by attaching itself to their necks. Its victims (called "mounts") become completely addicted to Ti Malice's kiss.
Hiram is the owner of the Aces High restaurant, the chicest meeting place for aces in the 1970s and 1980s. He is a powerful ace himself, with mastery over gravity. He had a short superhero career as Fatman.
Acrofatic: Not quite, but he is susprisingly light on his feet, considering that he uses his power to decrease his own weight.
Break the Cutie: Poor Hiram. His life takes a nosedive when he becomes a slave to the monstrous Ti Malice.
Camp Straight: Not as much as Tachyon, but Hiram is quite flamboyant.
More Than Mind Control: Initially, Hartmann doesn't use his power to directly manipulate Sara, though his empathy and charisma are superhuman nonetheless.
Real name Rosa-Maria Gambione, a Mafia princess that became stranged from her family, changed her name and became a New York district attorney. Later tried to become a leader in the Mafia, playing both sides.
Becoming the Mask: At first she tried to justify her taking over the Mob as leading them in a more civilized direction, but she kept digging herself in deeper and deeper...
Zorro Mark: Leaves an ace of spades at the sites of his revenge killings.
Joker leader in the Jumper books. Bloat is an immobile, gigantic montain of pale flesh, with the head and shoulders of a teen boy perched atop it. He has extraordinarily potent Psychic Powers. His home base is the Rox, formerly known as Ellis Island.
Anti-Villain: Bloat is quite sympathetic, even though he is technicaly the Big Bad for the Jumper trilogy.
Chrysalis is the owner of the Crystal Palace nightclub in Jokertown, and is the unofficial queen of the Joker underworld, brokering information to all parties. Her skin is invisible, her organs and skeleton exposed for all to see.
The host of a Good Morning America style TV show. Peregrine is a superheroine who is technically considered a Joker but has kept her natural beauty. She has big, bird-like wings and is capable of flight. This leads many to consider her an Ace.
Cute Monster Girl: Technically she's a joker because she has wings, leading to the saying, "A Joker, is a Joker, is a Joker...unless it's Peregrine"
Killed Off for Real. An odd version. In Fort Freak, it is revealed that John, one of the personalities controlling Oddity, has early-onset Alzheimer's. In order to stop this, Oddity takes the trump cure, which works-to a point. Patti, who is controlling the body at that time, is ejected with her own mind and body fully intact from Oddity, while John and Evan's minds and bodies stay behind in the form of Oddity, who then die.
