Onix

Onix is a Rock/Ground-type Pokémon that first appeared in Pokémon Red Version and Pokémon Green Version (later localized as Pokémon Red Version and Pokémon Blue Version). From Generation II of the Pokémon series onward, it evolves into Steelix by being traded while holding a Metal Coat. In Super Smash Bros., it has a chance of being summoned from a Poké Ball attacks by using Rock Throw; after being spawned, it jumps to the top of the stage and rains boulders down onto the stage. Onix can damage opponents itself while dropping rocks, and the rocks launch away opponents if they hit. If opponents touch Onix before it rises upward, they also take damage.
