Toad

Toad is a character who is Princess Peach's attendant and a long time protector of the Mushroom Kingdom. He is actually a singular character among an entire species of look-alikes (much like Yoshi is to the Yoshi species), leading to confusion over some of his appearances. He usually has the role of a supporting character who tries to help Mario and Luigi on their adventures, although he occasionally has been as a main protagonist, such as in Super Mario Bros. 2 and his starring role in Wario's Woods. He also appears regularly as a playable character in the Mario spin-offs. His role as Peach's steward has sometimes instead been given to Toadsworth.
