Was'nt it the True Arena in Super Star Ultra, and RTD. Well in regards to the color-palette, I think it should be similar to peach who has Daisy's colors, and hair. So that when you turn to the pink variation of Meta Knight, in would have the mask slits going north, and south, and the wings should have feathers, and you know sword, and sheild. But then thats too much different from Meta Knight. And they got rid of all the duplicate fighters in SSBM, you know Dr. Mario, Young Link, Pichu. It be cool though if they had Daisy, Galacta Knight, Pichu, and other characters under some sort of side menu under Meta Knight, Pikachu, and Peach.
