Korean national Kim Il Sung was the youngest member of the Marauders
, the superhuman assassins responsible for massacring the underground mutant community known as the Morlocks
. Though the Marauders were all seemingly killed during a demonic invasion of New York City, Sinister
possesses the technology to perpetually clone them from samples of their DNA. Seemingly more concerned with his fashion sense than the task at hand, Kim refuses to wear a costume like his teammates. Primarily a non-combatant, Kim prefers to use stealth and subterfuge to assault his targets. Borderline psychopathic and gleefully sadistic, Kim shows little compunction about killing and should not be underestimated.
