Yeah. If Doublade does get an evolution (hopefully) it would probably have a shield of some sort. Or it could end up being three swords, with the one in the middle being giant. There's also a possibility that it could end up as a single sword Pokémon again, but just better looking overall. But Doublade looks like it could do great on it's own. It might just turn out to be like Diglett, a Pokémon that only evolves one :3
