>>44259213The most logical thing to do would be to make it an Ice Type. That matches its color pallet, weakness to Fire and is fitting because ice IS a crystalline structure.
Can't easily replicate the water resistance without giving it a special Ability, but that's fine. The best options would be to make it Ice/Rock, Ice/Steel or perhaps Ice/Fairy.
It would probably specially defensive instead of physically, and it would have a region split-evolution, evolving into something other than Steelix.
Mirror Armor would be good, but Ice is SUCH a shitty defensive Typing and this thing isn't gonna be fast, so it basically needs a really good defensive Ability to work.
