Steelix was practically built for Trick Room teams. Sheer Force drops secondary effects for a straight power boost, and 200 base Defense gives it real offensive presence. Electric and Poison moves can't touch it, which offsets the 4 weaknesses somewhat. Known as the Iron Snake Pokemon.

Defense leads and Speed gets almost nothing. That's Steelix's stat line in a nutshell. 2 stats sit in respectable range, but the spread is brutal. Very hard to catch and yields 2 Defense EVs.

It is said that if an Onix lives for over 100 years, its composition changes to become diamond-like.

Sword

It is thought its body transformed as a result of iron accumulating internally from swallowing soil.

Shield

Steelix Weakness

Excellent

Steelix is weak to Fire, Water, Fighting, and Ground-type moves. On the flip side, it's immune to Electric and Poison-type moves entirely. With 8 resistances, the defensive profile is strong. Steelix's physical bulk (base 200 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Getting Steelix requires a trade, not just grinding levels. The chain starts at Onix. Breed this form to get Onix eggs (average hatch time). HP grew the most through evolution (+40 over Onix), and Steelix peaks at 510 total stats.

Brave nature gives Steelix the slow physical lean it needs to trade hits effectively. Leftovers adds passive recovery each turn, max HP and Attack EVs split the difference, and utility options punishes anything trying to wall it.

  2. Steelix
    Step 2Steelix
  • Sheer Force changes the entire equation for Steelix. The 510 BST doesn't tell the full story. Ranked C-Tier as a trick room.

  • Steelix's biggest threats include Charizard (Fire), Starmie (Water), and Machamp (Fighting), all carrying super-effective STAB moves. Ground-type attackers are also a problem. At base 30 Speed, Steelix won't outrun any of these threats so switching to a resist is usually the safer play.

  • Onix evolves into Steelix while holding a Metal Coat. Steelix is the fully evolved form. At 510 BST, it's got solid stats to work with.

  • Sheer Force is what you want on Steelix. Every competitive set worth running is built with that ability in mind. The alternatives (Rock Head, Sturdy) work on paper but Sheer Force is what makes Steelix worth using.

  • Base 30 Speed is low. Priority moves or Trick Room are the way to go. On offense, Steelix is a physical attacker with base 85 Attack. Defensively? Tanky enough to absorb a few hits. Best used as a trick room.

  • Steelix appears in 18 games, including Gold & Silver, Crystal, and Ruby & Sapphire.

Obtainable through a trade evolution, Steelix appears in 18 titles across 8 generations since Gold & Silver. The evolution method adds a barrier that wild-catchable Pokemon don't have.
