Quite possibly the darkest figure on the list, Harman Smith is a wheelchair-bound assassin who is tasked with saving the world from Killer7's Heaven Smile terrorists. His special ability is the most unique on this list, and it could even be interpreted as being a form of psychosis (especially given how confusing the plot of Killer7 actually is). Harman Smith harbours seven alternative personalities/alter-egos that he is able to physically transform into. Each of these alternative identities - Coyote (thief), Dan (the Hellion), Mask De (wrestler), Kaede (telekinetic powers), Con (speed-demon), Kevin (knife-thrower) and Garcian (the cleaner) - has a different skill-set. Effectively, the Smith Syndicate comprises the ultimate killing machine. Perhaps, then, Harman should be considered a villain. His job is to kill people, of course. But as noted, the Killer7 use their murderous abilities to take down terrorists. They may be bloodthirsty and violent, but at least they seem to be on the "good" side...
