Darko was once a master of different forms of combat like for example, sword fighting. But after having used himself to seal the demon twins, Shaztorm & Darztorm, he became mad, and started to kill his own family and students, thankfully he was stopped by his fellow Demi gods Compliens, who manage to talk too the remaining part of Darko's mind. Making him stop long enough for them to send him to a pocket dimension.
