MegaMan Battle Network 6
He loses the Navi Mascot competition and gives lessons on assassination at the Central Town school. Dark Scythe's mission involves assassinating several gang members in the UnderNet. After taking his lesson and defeating him in a Net Battle, Lan gains his Cross Style. He hopes that he is never ordered to kill Lan or MegaMan, but will do so if hired.

Rockman EXE Beast
He lives in Beyondard and leads a subdivision of the human resistance. He shows more personality here, shown to be clever and cunning, and full of last minute resorts, like throwing a frag grenade onto one of Lord Wily's helicopters. It is revealed that he used to be a mercenary, but was devastated when he failed a mission. Commander Mask consoled him and he has been serving the Commander ever since to repay his kindness. He is also implied to be the planner of the creation of the super cannons engineered to fight Cybeasts.
