Toad (aka Toad Bitch Ass) is Toadette's older twin brother and hero of Captain Toad: Treasure Tracker. He is a resident of the Mushroom Kingdom, which is ruled by Princess Peach, along with Princess Daisy and others. He is very cowardly, much like Luigi and is fearful of Bowser. He regularly tells Mario where he needs to go to rescue Princess Peach, in a show of gratitude when he is rescued, putting his navigational skills to use. In Dashie's Mario Kart 8 gameplays, he is an occasional nuisance.

In Captain Toad: Treasure Tracker, he rescues Toadettes's from a giant eagle which has swooped her up and kidnapped her, but he is unable to jump due to the large weight of his backpack.
