Is Steelix Good in Gold & Silver Playthrough?

Trade Onix with a Metal Coat. Steelix is one of the most physically defensive Pokemon in the game. Steel/Ground typing gives it a pile of resistances. Jasmine uses one as her ace, and if you get your own, it handles most of the late game physically.

How to Get Steelix in Gold & Silver

Steelix needs an Onix traded while it holds a Metal Coat. No wild ones, and like every trade-evolution it takes a partner to complete, so the rare Metal Coat is only half the battle.

Wild Steelix may be holding when caught:

Metal Coat (2% chance) Powers up steel-type moves. (HOLD)

Catch Onix at any of these 5 spots to eventually evolve into Steelix.

Fastest Path

The best route is Breed w/ Shiny Parent, about 1 in 64 on each try.

Step 1 · Encounter Method2 in Gold & Silver

Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.

Breed w/ Shiny Parent: Eggs inherit stats from a shiny parent, so about 1 in 64 hatch shiny. A shiny Ditto helps every egg, and any other shiny parent (the red Gyarados works) helps only eggs of the opposite gender.

How many you have done, or plan to do.

How is this calculated?

Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.

chance after N tries = 1 − (1 − p)^N,  where  p = 1 / odds per try

Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.

The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.

These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.

Where these shiny odds come from: Read our full methodology

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 9 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.

Pokedex Entry

Its body has been compressed deep under the ground. As a result, it is even harder than a diamond.

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

Steelix Gold & Silver Guide

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

  • Steelix is obtained by trade-evolving Onix. Catch an Onix first, then trade. The Metal Coat must be held during the trade. Bring one over from a sibling Gen 3 game if needed.

  • In Gold & Silver, Steelix plays as a trick room. It's slow, so Trick Room or priority moves are key. so pick your spots carefully. Earthquake is the primary attack. Set up with Curse when you get a free turn.

Game Availability

Since debuting in Gold & Silver, Steelix has appeared in 18 titles over 8 generations. Along the way, it received a Mega form in Generation 6, keeping it relevant across different competitive metas.
