Beastmen

Beastmen, refered to as Beasts in Final Fantasy Legend III, are a humanoid race seen in SaGa 3: Jikuu no Hasha. In this game, they serve as sort of a hybrid race of humans/Espers and monsters, where the human-like races will transform into beastmen by eating meat dropped by monsters. Beastmen can then transform into true monsters by continuing to eat meat.
