Princess Peach

Princess Peach was a minor character who only appeared in Super Mario. In a chain of a events happening before the episode she appeared in, Princess Peach was very likely kidnapped by Bowser along with Toad. Before the episode, Orange arrived in Bowser's castle, annoyed Bowser until he got angry and left, and hung out with Toad and Peach for a little while and finally, Bowser kicked Orange, Toad and Peach out of the dungeon. She later appeared in Mario Kart slipping on the juice that Orange had spat on the road, causing her to crash her cart along with many others.
