Seriously. Ridley is a new combination of things for Smash Bros., but literally nothing that makes up that combination is new.
Weird posture? DK, Greninja, Wolf all work.
Large size? Dedede, Bowser, Charizard, DK all work.
Wings? Pit, Meta Knight, and Charizard all work.
Tail? Mewtwo, Charizard, and Diddy Kong all work.
Bonus points to DK who is large with weird posture. Bonus points to Charizard who is large, has wings, and a noticeable tail.
There is nothing new here. Ridley can have a large size, not-full-on-humanoid posture, a tail like Diddy Kong's and wings that accumulate to an air-based character. It would be strange. It would be new. But all of the PARTS have been done before in several combinations.
A character with new never-before-seen fighting style bias? Ridley would be a first, but we just got Little Mac who does the OPPOSITE in functioning disturbingly well on the ground and disturbingly poorly in the air.
