Steelix
Diamond

Tempered underground under high pressure and heat, its body is harder than any metal.

Pearl

It chews its way through boulders with its sturdy jaws. Its eyes can see in the darkness underground.

Platinum

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

Heartgold

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

Soulsilver

It’s said that if an ONIX lives for 100 years, its composition becomes diamondlike as it evolves into a STEELIX.
