OnixEvolutions #61 Pokémon Card

Onix, the Rock Snake Pokémon, is a colossal creature known for its immense size and rock-hard body. Introduced in Generation I, Onix is a pure Rock-type Pokémon that evolves into Steelix when traded holding a Metal Coat. Its natural habitat is deep underground, where it carves out vast tunnels, consuming earth and rocks to grow larger and harder. Onix is a formidable presence in the Kanto region, often depicted as a guardian of caves and a challenge for aspiring trainers. Its diet consists primarily of the minerals it encounters while burrowing, which contributes to its strong, durable composition. In the anime, Brock's Onix is a memorable companion, showcasing its loyalty and raw power. Onix's imposing appearance and role as one of the original 151 Pokémon have cemented its place as an iconic figure in the Pokémon franchise, representing resilience and the raw power of nature.
