Primal Registeel

Despite Primal Registeel's intimidating size, it is very gentle around small Pokemon, designating itself as their protector.

Giant intimidating robots/mechs being super gentle with small creatures (mostly birds) is my weakness ;; Design for primal Registeel, one of the coolest Pokemon around. Seriously. I imagine Primal Registeel to have not only the hardest metal on the planet, but in the universe itself, being reinforced by the power (glowing a bright yellow on the outside, but a crimson on the inside which isn't currently visible) that flows through its body from the core of the planet.

Primal Registeel

Type: Steel
Height: 13'1.5'' / 4m
Weight: 1200lbs / 545.45kg

HP: 80 -> 80
ATK: 75 -> 85
DEF: 150 -> 190
SP ATK: 75 -> 85
SP DEF: 150 -> 190
SPE: 50 -> 60

Ability: *NEW* Impenetrable Fortress - Every time a physical attack makes contact with this Pokemon, its defense increases by one stage. Every time a special attack makes contact with this Pokemon, its sp. def increases by one stage. 

Signature Move: *NEW* Inner Guardian - PP = 2 - Primal Registeel gathers its life energy to harden its body. Sharply increases defense and special defense in exchange for one half of its max HP.

Registeel gains a huge boost to its defense and special defense after undergoing primal reversion. I think his ability and skills make him very, very strong defensively, even though there are only a few contact special attacking moves. Either way, not sure if OP or not, but it really just buffs him up to the extreme. Edit: Tweaked some numbers haha~
