Toad is a recurring character who appears in not only the Paper Mario series, but as well as the mainstream Super Mario Bros. series of the Mario series (a trait shared with Mario, Luigi, Princess Peach, and Bowser). While he appears most identical to most Toads in terms of his appearance, Toad is actually an entirely different and unique character by his own means. He constantly plays the role of Princess Peach's loyal servant or her Mushroom Retainer. His roles in the Mario RPG and Paper Mario games are often minor; however, he is still often seen to being rather courageous as he tries to assist the Mario Bros. to the very best of his ability.
