Onix is one of the most recognizable Rock-type Pokémon in the series, but in Pokémon Legends: Z-A, many players quickly realize that Onix’s real potential is unlocked only after evolution. If you are unsure whether Onix can evolve, what item is required, or how the evolution works in Legends Z-A, this guide is written to answer every related question clearly and in detail.
Can Onix Evolve in Pokémon Legends: Z-A?
Yes, Onix can evolve in Pokémon Legends: Z-A.
Unlike traditional Pokémon games, where Onix evolves through trading, Legends Z-A follows the modern Legends-style evolution system. This means:
- No trading is required
- Evolution is item-based and player-controlled
- You can evolve Onix entirely in single-player mode
Onix evolves into Steelix, a far stronger and more defensively reliable Pokémon.
What Does Onix Evolve Into?
Onix evolves into Steelix, which brings significant improvements.
Onix → Steelix Evolution Benefits
- Type Change: Rock/Ground → Steel/Ground
- Major Defense Boost: Steelix has extremely high Defense
- Better Battle Performance: Stronger survivability in both wild battles and boss encounters
- Improved Resistance: Steel typing adds many useful resistances
If you plan to keep Onix on your team long-term, evolving it into Steelix is highly recommended.

Requirements to Evolve Onix in Legends Z-A
1. Metal Coat (Mandatory Item)
To evolve Onix, you must use a Metal Coat on it.
Key points:
- Metal Coat is a special evolution item
- Simply leveling up Onix will not trigger evolution
- You do not need to trade Onix while holding Metal Coat
This is a major change from older Pokémon games and aligns with the Legends evolution philosophy.
2. No Level, Time, or Location Restrictions
In Pokémon Legends: Z-A:
- There is no minimum level requirement
- Evolution does not depend on the time of day
- No specific area or biome is required
As long as you have a Metal Coat, Onix is eligible to evolve immediately.
How to Get Metal Coat in Pokémon Legends: Z-A
Metal Coat is considered a mid-value evolution item, meaning it is not guaranteed early but is accessible through multiple methods.
Common Ways to Obtain Metal Coat
- Exploration & Item Pickups: Found in metallic or industrial-themed areas
- Merchants or Shops: Available for purchase later in the game
- Side Quests & Requests: Certain NPC quests may reward evolution items
- Rare Drops: Occasionally dropped by specific Pokémon or found in distortions (if applicable)
If you explore thoroughly and complete side content, you will almost certainly obtain a Metal Coat without grinding excessively.
Step-by-Step: How to Evolve Onix into Steelix
Once you have Metal Coat, evolving Onix is simple:
- Open your Satchel / Inventory
- Select Metal Coat
- Choose Use
- Select Onix from your Pokémon list
- Confirm the evolution
After confirmation, Onix will evolve instantly into Steelix.
Why You Should Evolve Onix into Steelix
Many players hesitate because Onix is iconic, but Steelix is objectively superior in most scenarios.
Key Reasons to Evolve:
- Massive improvement in Defense stat
- Better typing for late-game battles
- Increased usefulness against stronger wild Pokémon
- More reliable tank in team compositions
Unless you are deliberately running a challenge or thematic team, Steelix is the better choice.
Common Mistakes Players Make
- Waiting for Onix to evolve by leveling up
- Assuming trading is required (it is not)
- Using the wrong held item
- Holding a Metal Coat instead of actively using it from the inventory
Understanding these mechanics saves time and avoids frustration.
