Xombi, also known as David Kim, is a superhero in the Dakotaverse published by Milestone Media. His career began as a scientist, where he developed experimental nanomachines that could cure any damage to the human body. Kim was injured and his lab assistant injected him with the nanovirus to save him, which granted him permanent immortality and indestructability. He also has limited control over the nanites that allows him to break down simple elements and re-construct them into new forms. Xombi was created by John Rozum and Denys Cowan, first appearing in Xombi #0. (1994)
