Is Steelix Good in Brilliant Diamond & Shining Pearl Playthrough?

Trade Onix with Metal Coat, or catch wild in the Underground. Steel/Ground with massive Defense. Byron uses one and for good reason. Handles Roark, Candice, and Aaron. The low Speed and Sp. Def are liabilities but the physical bulk is immense.

Steelix Weakness

Steelix is weak to Fire, Water, Fighting, and Ground. 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.

Steelix Brilliant Diamond & Shining Pearl Guide

  • In Brilliant Diamond & Shining Pearl, Sheer Force changes the entire equation for Steelix. The 510 BST doesn't tell the full story. Ranked B-Tier as a trick room. Earthquake with Leftovers is the standard set.

  • Mega Evolution isn't available in Brilliant Diamond & Shining Pearl, but Steelix does have a Mega form in Gen 6-7 games (X/Y, ORAS, Sun/Moon). Mega Steelix hits 610 BST.

  • In Brilliant Diamond & Shining Pearl, 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.

  • Steelix is obtained by trade-evolving Onix. Catch or evolve a Onix first, then trade. Trade needs a Game Boy Advance link cable and a second GBA running another Gen 3 game (FireRed, LeafGreen, Ruby, Sapphire, or Emerald). Trade Onix to a friend, then have them trade it back. The 2026 Switch re-release supports the same trade through local wireless on the Pokemon Center 2F Wireless Club, with no cables required. The Metal Coat must be held during the trade. Bring one over from a sibling Gen 3 game if needed.

  • 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.

Game Availability

Since debuting in Gold & Silver, Steelix has appeared in 18 titles over 9 generations. Along the way, it received a Mega form in Generation 6, keeping it relevant across different competitive metas.
