GIGANTAMAX BLASTOISE

As with Venusaur, I think Gigantamax Blastoise easily outshines Mega Blastoise as a design; all the Mega did was have a slightly different head structure and longer guns. Giant Blastoise turns its shell into an entire arsenal of threatening cannons, leaning more into the oddly mechanized look that always made Blastoise stand out among all other, more organic looking starters.
