The Step-by-Step Guide to Evolving Onix
Evolving Onix is a unique process that has remained consistent since its evolution, Steelix, was introduced in Generation II. Unlike Pokémon that evolve by leveling up, Onix requires two key components: a special item and the help of another trainer.
Here’s the process:
- Obtain a Metal Coat: This evolutionary item is essential. Its location varies by game, but it can often be found held by wild Magnemite or obtained as a reward during the storyline.
- Give the Metal Coat to Onix: Make sure your Onix is holding the Metal Coat. You can do this from the party menu in your game.
- Trade Onix: The final step is to trade your Onix with another player. The evolution will trigger automatically upon completion of the trade. The other player will then need to trade Steelix back to you.
Keep in mind that this evolution is irreversible, so be certain you want to evolve your Onix! Below, you can see the full evolution path for this Pokémon.

Meet Steelix: The Iron Snake Pokémon
Upon evolving, Onix becomes the formidable Steelix. This transformation brings significant changes, most notably its typing, which shifts from Rock/Ground to Steel/Ground. This new combination grants it an impressive list of resistances and only a few weaknesses, making it a defensive powerhouse.
Steelix is renowned for its sky-high Defense stat, allowing it to withstand powerful physical attacks with ease. While its Speed remains low, its role on a team is clear: to act as a sturdy wall that can cripple opponents with moves like Stealth Rock and hit back with powerful STAB (Same-Type Attack Bonus) moves like Earthquake and Iron Head. Its sheer bulk makes it a valuable anchor for many competitive and in-game teams.

No, Onix's level does not affect its evolution into Steelix. It can be evolved at any level, from Level 1 upwards, as long as it is traded while holding a Metal Coat.
Where can I find a Metal Coat?
