In The Grim Adventures of Billy and Mandy, The Tooth Fairy is a cowboy in search of the perfect tooth to complete his smile, which is missing a tooth.
The Tooth Fairy is a brown-haired male with a long pointed nose. He wears a white cowboy hat and gloves, an orange shirt with a sheriff badge, brown pants, and cowboy boots. He has small wings protruding from his back.
He is egocentric, and craves fame, but has the mannerisms of an archetypical cowboy.
- He, as a fairy, is capable of flight
- He possesses The Gold Star Scepter, which is even more powerful than The Reaper's Scythe. It is able to turn victims into fast food.
In The Good, the Bad, & the Toothless , he buys Billy's tooth from Sperg in order to make his own smile perfect, and try to become a star. However, since the tooth was stolen, Billy, Mandy, and Grim go to get it back from him in a showdown. He is later revealed to be the elderly man Billy was talking to at the beginning of the episode.
In The Good, the Bad, & the Toothless ,he is revealed to have aged into an old man, but in King Tooten Pooten, he is shown to still be young when trying to obtain Irwin's tooth in a flashback.
