Hawkheart

Hawkheart is an evil lil' rat, the WindClan medicine cat, who killed Bluebloated's drunk, mom, Moondrunk, after she killed WindClan's medicine supply, because of a mark and a piece of catmint on a vole's pelt. Hawkheart was once the most fierce warrior in WindClan, and that's why he's crazy. Only StarClan knows who let this insane guy become a medicine cat.
