The Forest King is a large and monstrous-looking tree creature, standing several stories high and has what appears to be another face in his abdomen and several thick branches covering his body that act as his limbs. His own face sports five pitch-black eyes and a mouth full of hole-like openings.
The Forest King sees humans as nothing more than mere fertilizer that his kind needs in order to carry on his scheme of returning the lost greenery to Earth.
Fall of the Hero Association ArcEdit
After four heroes of the Association fought and harmed his followers, the Forest King himself confronted the heroes and easily defeated and captured them. As he was about to feed them as fertilizer to his kind, another hero appeared, annihilated his entire army, and then proceeded to defeat the Forest King himself.
Abilities and PowersEdit
The Forest King could singlehandedly defeat four professional heroes of the Hero Association with little to no effort, with the heroes being impotent against him.
Immense Strength: The Forest King could use his branches to easily crush with great force anything in his grasp.
Immense Durability: The Forest King could endure the attacks of an A-Class Hero without any scratch.
