Fan Kwan, AKA Mad Monkey, is a Chinese-American mutant (re-skinned orc ancestry with deep orc heritage). 18 years old and just graduated from High School when the campaign starts, he's been raised on kung fu movies, anime and comic books, and was trained in Shao Lin kung fu by his uncle, a Taoist monk.
At the age of 14, he began to manifest mutant powers associated with his ability to channel chi or ki, granting him abilities exceeding those of a normal human martial artist. When he was 16, these powers would be put to the test when his family's Asian food emporium, Fan Imports, was targeted for extortion by the mysterious clan of assassins known as the Hand. His family refused to join the Hand or pay them protection money, so they sent Hand ninja assassins to murder the family.
Most of Fan Kwan's family were slain by the Hand, but his uncle (and kung fu instructor) survived, and found Fan Kwan mortally wounded and dying. He retrieved a magical herb known only to the masters of the style of kung fu practiced by Fan Kwan and his uncle, and treated the dying mutant teenager with a potion brewed from this herb. Not only did the potion save Fan Kwan's life, it fully healed him, and amplified his mutant ki-channeling power.
Fan Kwan's uncle continues to train the teenager in the way of Shao Lin kung fu, and both keep a low profile, always looking over their shoulders in search of the next attack by the Hand. Fan Kwan swears he will avenge his family, but he must first find allies and become mighty enough to survive such a perilous mission...
