Killer T Cell is an immune cell inside the Body, and resides inside the lymph nodes with the rest of the killer t cells. He patrols the bloodstream daily to exterminate bacteria and other threats to keep the other cells and the body safe. He's a little scary looking, with large muscles and a scar on his cheek. He has a large black hat that says KILL on it, and blonde hair under it. He's actually very sweet despite his looks, and likes ice cream.
