Habitat

Mountains, subterranean caves and tunnels

Overview

While Onix form subterranean tunnels dozens of meters below the surface, Steelix have been recorded to dig out trails nearly a kilometer underground. The immense pressure of the earth above at this level can crush most living organisms. However, their bodies are in fact harder than diamond, compressed by the extreme pressure of their habitats. A common legend is that Onix living to be over 100 years will have experienced enough force to compress their bodies and become Steelix. In the wild, scientists believe that age has little to do with their evolutions; Onix evolve into Steelix as they eat through rock and absorb the iron within. Combined with intense pressure, their bodies eventually turn dense and metallic (such a process can be domestically replicated with Metal Coats). Their eyes are adapted to see in the dark, and their strong jaws can crunch through even the hardest boulders. Their bodies are speckled with thousands of tiny, reflective particles from the minerals they eat. These particles sparkle beautifully in the sun.
