Onix (イワーク, Iwaaku) is a Rock/Ground-type Pokémon introduced in Generation I.
Ikran's Lost OoT/Pokémon crossover[]
Onix was useful offensively, defensively, and providing bridges, even protecting the heroes from falling debris by the erupting volcano.
The ReBoot Multiuniverse[]
Onix was trapped with Akari, her other Rock-Types, and the heroes in the Warriors Game with the agonizing Mike the TV! Onix plowed thru each of the Game Sprites, even provided a bridge or two for the gang. But his greatest moment was when he accidentally grabbed Akari's metallic armor away from her, and the attachment made him evolve into Steelix!
