Although why would he get crits though. I mean that would make him wayyy too overpowered. Adding metal to his targets is a little overpowered. He already destroys pretty much everything, if you want a critter like him just use luffy because he one shots I think every metal enemy anyways. I think what would be more fitting is gaining behemoth slayer and attack rate up for some ultra talents. That way he will be able to get multiple hits in before he dies. Later in the game he tends to maybe get the chance for one hit because of his shit range and slow attack rate. I mean when dealing with enemies like prof A ringmaster A and other enemies that have high dps and high range that usually come with lots of support. But if I were to give him one more I would say maybe increase his range a little.
