Human Bird Grass (ヒトトリグサ, Hitotorigusa, Viz: Venus Peopletrap) was a Mysterious Being that attacks Narinki, the sponsor of the Hero Association with Junior Centipede.


Human Bird Grass is a big monster with the appearance of a carnivorous plant.


His personality is left rather ambiguous, but he seems to be rather impatient and hungers for human flesh.
