Xombi
Xombi is a superhero published by DC Comics. He first appeared in Xombi #0 (January 1994) and was created by John Rozum and Denys Cowan. Fictional character biography
Xombi was a Korean-American scientist named David Kim from West Orange, New Jersey. He developed a nanotechnological virus capable of extensive tissue regeneration. Before David Kim could test his invention, a villain named Dr. Sugarman broke into his lab and tried to steal the virus. In the fight, Kim was critically injured, and his assistant Kelly injected him with the virus in an attempt to save his life. However, since the nanites used available matter to restore Kim, Kelly—who had laid his body on her lap—was partially "devoured" by the nanites. Kim became a "xombi" - a potentially immortal, technologically enhanced human being. This embroiled him in the affairs of various races of supernatural beings that secretly lived among humanity for millennia, known collectively as the shadow worlds. Post-Infinite Crisis

Due to the combined effect of the destruction and recreation of the multiverse and the timeline-altering powers of Anansi, a new divergent timeline was created in which David Kim, the most worthy man alive, became Green Lantern instead of Hal Jordan. Kim was one of a group of alternate Justice League members who helped restore the original timeline. Xombi (along with fiancée Dalia Rose and friend Julian Parker) debuted in the DC Universe in issue #26 of The Brave and the Bold, teaming up with The Spectre to fight a ghost which was killing and sucking the lifeforce of other ghosts, vampires, and undead. Xombi Vol. 2
A second Xombi series debuted in DC Comics in May 2011, and ran for six issues, which were collected in a trade paperback. It was written by John Rozum, with art by Frazer Irving. Powers and abilities
