Captain Immortal

An acrobatic martial artist and younger brother to the Comet, Captain Immortal possesses no special resistance to physical harm or immunity to death. He can be killed, and often is, but once lethal conditions are removed or if whatever remains of his body is moved to a location where conditions not lethal to humans are present, he is resurrected within moments. He is known for his complete lack of self-preservation and his wild, manic, fighting style. He is also considered by most of the superhero community as being completely unhinged; in fact, it is not clear he would still be a member of the Fabulous Five if not for the advocacy of his brother.
