An eroded regi Pokémon

a ghost-rock type with a signature ability:

Sedimentary entrapment:

creates a layer of spikes (as in the move effect) while keeping the Pokémon trapped in battle
and move:

Tidal thrash:

a 90 power move which can cause confusion on the afflicted Pokémon, side effect: will either hit as a rock or water type move, which ever is more effective

pokedex entry:

This is what seems to occur after a regirock has eroded far too much out of repair, it has absorbed most of the water through its rocky shell and uses it for battle

alt entry:

This ghostly shell of a former legendary species isolates itself as it tries to egress from watery premises.

this Pokémon can be seen making a jogging jolt as rain comes to tuition
