Invincible (comic) - Supporting Cast - Enemies

Enemies

• Mauler Twins: An evil scientist and his clone, whom both continuously argue as to which is the original. After the original was definitely killed, making them both clones, they switched to arguing which is the original clone. Recently both Mauler twins were killed by Kid Omni-Man; with no one alive to clone them it is uncertain if they will come back.

King Lizard is the only member of the Lizard League to currently be alive.
• Furnace: A villain with a massive steam-powered iron suit armed with dual flame-throwers and jets. He is actually a man made entirely of liquid heat from which the suit earns its power.
• Magnattack: A villain for hire with the ability to apparently push metal objects away from him, hence his massive armor plated suit.

• Isotope: A character once thought to be modeled after real life comic book store owner James Sime of Isotope Comics in San Francisco, but as revealed by Robert Kirkman in the letter column of issue #67 - the resemblance "is a complete coincidence... James Sime is a friend of the book, but Ryan didn't even know what he looked like when he drew that issue."
• Giant: An eight-year-old boy who was pulled into another dimension where he transformed by a sorcerer into gigantic orange-red cyclops. He became a king in the other dimension until he was teleported back by one of his enemies.

In 2003 and 2004, Image and Robert Kirkman published several other superhero series: Tech Jacket pencilled in a manga style by E. J. Su (cancelled at #6), the 3-issue Capes Inc. series drawn by Mark Englert and three oneshots starring Brit, the first two with artwork from Tony Moore and the third with artwork by Cliff Rathburn.

In 2007, Brit was launched as an ongoing full-color series written by Bruce Brown, with artwork by Cliff Rathburn. The series is overseen and edited by Robert Kirkman. In late 2007, a two issue mini-series starring Atom Eve was released.

Tech Jacket was first collected as a digest-sized, black and white graphic novel and later reissued in regular sized, full color and a cover scheme similar to Kirkman's other trade paper backs. Capes was collected as a trade paperback in summer 2007, and the three Brit one-shots were colored by Val Staples and published as a collection in 2007, as well.

At first shown to barely coexist in the same universe, the characters have since been integrated into Invincible's book. Tech Jacket was an ongoing series that tied into Invincible #27, and the character has been seen in the background of various battles during the series. The characters from Capes have also been supporting characters seen mainly in large superhero battles Invincible participates in, and the series ran as a back-up in the Invincible book starting with #27. Brit has had an even less substantial role, appearing a couple of times in the aforementioned brawls (understandable considering that after the last book Brit was somewhat-retired). In The Astounding Wolf-Man, Art, Invincible's tailor, appeared, designing the title character's costume. Wolf-man has also appeared in Invincible #48 & 49.
