Super Princess

Super Princess is an alternate form of Princess Toadstool seen only in The Super Mario Bros. Super Show!, more specifically, in the episode "The Trojan Koopa / Texas Tea".

In the episode, when the Koopa Packs have Mario and Luigi surrounded, Princess Toadstool gets a Fire Flower and becomes Super Princess. The color of her dress changes to a more purple color and Super Princess grows more powerful (thought she doesn't shoot fireballs). She is able to defeat the Koopas.
