Fictional character biography
David Kim is a Korean-American scientist from West Orange, New Jersey who developed regenerative nanotechnology. Before Kim can test his invention, a villain named Dr. Sugarman breaks into his lab and attempts to steal the virus. In the ensuing fight, Kim is critically injured and his assistant Kelly injects him with the virus in an attempt to save his life. However, the nanites use available matter to restore Kim, partially devouring Kelly in the process. 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.
Due to the combined effect of the destruction and recreation of the multiverse and the timeline-altering powers of Anansi, a new divergent timeline is created in which David Kim became a Green Lantern instead of Hal Jordan. Kim is one of a group of alternate Justice League members who help restore the original timeline.
