Ghost/Fighting
"This Pokèmon is as fierce as a warrior. It will defend even after it is on its last legs and fights viciously. It feeds off the positive emotions of others to stay in good health, but becomes aggressive toward those who bring harmful energies around it. Legend has it that these Pokèmon are the ghosts of warriors from a distant past."
