A female Beastman in SaGa 3: Jikuu no Hasha: Shadow or Light
Beastmen, referred to as Beasts in Final Fantasy Legend III, are a humanoid race seen in SaGa 3: Jikuu no Hasha. In the Game Boy version, 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 beasts and monsters. Beastmen can then transform into true monsters by eating monster meat. However, if a monster eats a beastman's meat it will transform back into a beastman.
In SaGa 3: Jikuu no Hasha: Shadow or Light, eating a beastman or monster meat may not transform a human or esper into a beast. It may instead transform a human into an esper or vice versa.
