Lets make a thread on creating Alolan Forms and future regional variants (If it's going to be recurring that is.)

Alolan Onix -> Alolan Steelix
Type: Rock/Fairy -> Steel/Fairy
Ability: Water Absorb
Description: Long ago, a group of Onix migrate into caves with water systems. Despite the Rock/Ground typing, they start living in the lakes. As a result of the pressure of the deep lakes, it's rocky hide becomes crystal-like. The Fairy-typing seems to come from the lakes' mystical power. People sought after the crystal hide of this majestic beast.

I need help with Gen III Regional Variants. Post some ideas and I'll make them.
