Doom (character)

Going by the name Doom:

Once, was 's military instructor.

Long after everyone else on Phobos was dead (the only other survivor came to be known as ), he kept fighting, determined to send out a warning to Earth before the demons could claim him.

Distracted and intelligent sounding, (but not a member of the intelligentsia, more like a well-educated tradesman) this guy may be a few cards short of a full deck, but his training serves him well. He's a bad-ass in the arenas.
