steelix

Steelix is a Steel and Ground type Pokémon that evolves from Onix under immense pressure, a colossal iron serpent that burrows deep underground. Its body is a chain of grey metal segments with a massive jaw full of sharp teeth, sharp crests and a tough, glinting surface. It can Mega Evolve into a spikier form studded with crystal. Artists often contrast its huge size with tiny trainers beside it.
