If they ever made Alternate Costume DLC in Smash 4, these are some ideas for what Mario could get. I'm thinking of making some of these for other characters as well.The top row are the costumes that are already in the game, and the bottom row are the new ones. The first three ones at the left are from Smash 64. The fourth one is a reference to the original Fire Mario costume from the first SMB. The fifth one is Flying Mario from Super Mario Galaxy. The sixth one is his costume from Mario Strikers Charged. The seventh is his Tanooki Suit. The eighth one is the Boomerang Mario costume from Super Mario 3D Land, and the ninth one is a black version of it made to resemble Hammer Mario from Super Mario Bros. 3.I had other ideas, but I'm considering saving them for Luigi, like the Frog Suit. Since it's green it would fit Luigi better.Oh, and thanks to Yurimaster for suggesting the Boomerang and Hammer costumes.
