Crawler
Crawler is a member of the Slaughterhouse Nine.
Powers and Abilities
Crawler's power is adaptive regeneration. Any injury he suffers will heal in a way that makes the healed area resistant or immune to the source of the injury. This adaptive regeneration has turned his body into a monstrous form and is powerful enough to develop an immunity to Armsmaster's nanothorns. The regeneration also lets him develop countermeasures, such as his signature acid attack that converts dissolved flesh into more acid and the aforementioned nanothorns, where bodyparts that were disintegrated by the nanothorns turned into nanothorns themselves.
History

Crawler came to Brockton Bay with the rest of the Slaughterhouse Nine. He was killed by one of Bakuda's bombs, which turned his entire body into glass.
