In the mid 21st century, Captain Karl Taylor (also known as The Man in Black or Captain Death) was one of only two humans that the Myloki duplicated, creating an indestructible version. The result was imperfect, effectively an animated corpse. He was encased in concrete, which was surrounded by a titanium shell and put at the bottom of the ocean in the OCEAN FLOOR facility.
About 30 years later, the Myloki activated him. His body generated massive amounts of heat, melting his surroundings so he could escape. He later fought Grant Matthews. During the combat, Jamie McCrimmon managed to stab Taylor with a device developed by Dwight Graham, which disintegrated Taylor. (PROSE: The Indestructible Man)
