Hawkheart is a grumpy and broody medicine cat, but deep down he cares deeply about his clan. He killed Moonflower after ThunderClan raided WindClan and tried to destroy their herb stores, Hawkheart who was pissed at Moonflower for doing so and since that was his medicine basically to heal the clan, he killed her to protect them, but not without her slashing his face, and knocking the flower off his ear. His blood is now pink after Moonflower, who is now in StarClan, attacked him.
