Onix GxHidden Fates #36 Pokémon Card

Onix is a colossal Rock/Ground-type Pokémon introduced in Generation I, known for its serpentine body composed of numerous boulders. It evolves from no other Pokémon and can evolve into Steelix when traded holding a Metal Coat. Onix typically inhabits mountainous regions and caves, burrowing through the earth at high speeds, often causing tremors and creating tunnels that can span miles. Its diet consists primarily of rocks and minerals, which it grinds down to strengthen its body, making it harder and more durable with age. In the Pokémon games, Onix is famously associated with Brock, the Gym Leader of Pewter City, and his formidable Rock-type team, making it an iconic early-game challenge. In the anime, Brock's Onix is a recurring and powerful companion, showcasing its immense strength and loyalty. Onix symbolizes endurance and the raw power of nature, often depicted as a gentle giant despite its intimidating appearance, playing a significant role in establishing the physical diversity of the Pokémon world. Its unique appearance and memorable role in the franchise have cemented its place in Pokémon history.
