Though it doesn't mean to be, Arcroth is a destructive menace. It has too much power to control and constantly runs around venting that energy with swinging limbs and bursts of light, usually causing immense property damage in the process.

It can't keep still because its blood boils with energy. It is described in mythology as the Pokémon that shaped the universe with its 1,000 arms.
