Uses its claw as a gun (A literal pistol shrimp):
Beta Remoraid revealing that it was based on a gun:
Gigantamax Blastoise sporting a comical amount of guns:
Mega Blastoise:
Beta Octillary showing it is based on a tank:
Gigantamax Intellion uses its tail as a snipers roost and has a sniper rifle:
Dragapult is a Stealth Bomber:
Remoraid is still recognizably a Remington (with the context of its name) and Octillary is still recognizably artillery with its weird little barrel mouth.
I never clocked it I dont really know my guns. Makes complete sense now
