Flayt

Flayt is a Tristram power-ray, a massive creature resembling an Earth manta-ray, but more comparable in size to a whale. Flayt is known for latching onto the sides of passing ships and sucking their powers cells dry in Sector 2751. Flayt left hundreds of ships stranded without power or life support during the Tristram-Zanner Imperial War, in which he was one of the main soldiers in the field. He is now known to latch onto Green Lanterns and suck both them and their power rings dry.
