Onix, the Rock Snake Pokémon, is a colossal creature known for its immense size and rocky 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 typically deep underground, in caves and tunnels, where it carves out vast passages. Onix's diet consists mainly of earth and rocks, which it consumes to grow larger and harder. Its behavior is generally territorial, defending its underground domains with formidable strength. In the Pokémon games, Onix is often encountered early on, posing a challenge to trainers due to its high defense and resistance to normal and flying-type attacks. In the anime, Brock's Onix is a memorable companion, showcasing its loyalty and power in numerous battles. Onix's cultural significance lies in its depiction as a symbol of endurance and raw power, an iconic figure from the early days of the Pokémon franchise that continues to be a fan favorite.
