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", and in "The Adventures of Super Mario Bros. 3", more specifically, in the episode "Tag Team Trouble".

In the episode, when the Koopa Packs have Mario and Luigi surrounded, Princess Toadstool gets a Starman and becomes Super Princess. The color of her dress changes to blue and white, and Super Princess becomes more powerful (though she does not shoot fireballs). She was able to defeat the Koopas single-handedly. This is also in The Adventures of Super Mario Bros. 3's "Tag Team Trouble", which aired in 1990.

The Princess says "Princess P. to the rescue!", after getting the star, which is a nod to the name "Peach", which had only been the Princess's name in the Japanese versions of the games at the time.
