I still think that the rumored character is either Bandana Dee or Inkling, although someone from the Smash Wiki told me Bandana Dee may have the upper hand, or arm, I think it's a paw but I'm unsure. And I couldn't agree more with his reason, Inklings have costumes and a trophy in the game, and while that's not the reason why they don't seem right at the moment, it has to do with that, the costumes were made as cross-promotions for Splatoon, and that's the reason. Their game has been out for less than five months, and while it's been a huge success, I personally think they should have some time to sink in before being included in Smash, I think that for now the Splatoon content we have is enough. But I expect them in the next game.
