Hit-Monkey once lived in the mountainous wilderness as part of a clan of other monkeys. Few of the members of this clan took in a fugitive assassin and nursing him back to health with herbal remedies and hot springs. Hit-Monkey disagreed with this because he knew that someone would eventually come looking for the assassin. Once the nameless assassin regained his health, he began to practice some of his skills once more, practicing on snowmen. With his home and his tribe gone, Hit-Monkey set out on his journey as "a killer of killers" with a duffle bag full of guns.
