Manslaughter is a mutant or mutate supervillain, a killer and assassin by trade and a psychopath by nature.
He joined his life force with Andromeda, the Valkyrie, and Interloper to drive the Dragon of the Moon from Earth, and his body turned to dust.
[5] With the others, they later took on host bodies of living persons, and assisted Doctor Strange in battling and crushing the Dragon of the Moon.
[volume & issue needed] Manslaughter has minor psionic talents, notably limited telepathic powers enabling him to perceive the activity of the autonomic nervous systems of other people.
Using his psionic abilities he can safely stalk his prey while remaining within a very close proximity (even a few feet), and reveals his presence once it is too late for his victims to escape.
