Abyss birth was the result of domping toxic waste into the ocean near Makuhero City by some criminals. Unfortunately it was directly above an underwater robot-graveyard. The waste got absorbed by the remains of one of the many lifeless robots and fused it with a local parasitic coral. The result is an insatiable energy-vampire who attacks any mechanical lifeform and sucks out its energy with his tentacle-whips. As if weren't enough, it can also control its victims to an extend. Unforunately he got in contact with the criminal Deadeye and struck a deal with him. Now he works for Deadeye as long he can suck the energy of possible enemies.
