Unovan Sableye - Electric/Fighting
The Sableye of Chargestone Cave have eaten the electrified crystals. This have given them faster speed and electricity powers, developing the electric type. They eventually developed the Fighting type to make mining easier. They now also prey on Boldore and Gigalith for their crystals too.
Evolve into Geminight after leveling up while knowing Aura Sphere
Geminight - Electric/Fighting
Only the Sableye that manage to get strong enough can reach this evolution. Geminight are speedsters that mainly use their fighting moves to wear down enemies after using electricity to paralyze them. Most take a bit of the crystals on wild Gigaliths as that can keep them healed.
Have Galvanize and a rock based variant of Water Absorb as abilities
Rock Eater - Any rock attack will heal any pokemon hit with this move.
Also have an idea for a Galarian Mimikyu based off Wizard and Witch hats
