An intense hypochondriac, Chainclaw believes firmly that there is something very wrong with his systems, if not several things wrong, and nothing will convince him otherwise. He endlessly entertains visions of how he and his teammates are going to die in battle, every possible mishap that's remotely plausible, even several implausible ones. Once he starts fighting, though, his anxiousness is channeled into a wild, animalistic fighting fury. Chainclaw is an incredibly effective and ferocious warrior - so long as he doesn't notice that discolored spot on his exostructure.
