He made his debut appearance in the short "Bully for Bugs". He makes short work of the regular matadors, then a burrowing Bugs Bunny surfaces in the bullring. They battle back and forth but Bugs ultimately wins the war.
He later appeared in the opening scene of "Mexican Cat Dance", again quickly dispatching a matador. Toro's appearance in "Mexican Cat Dance" is reused footage from "Bully for Bugs".
Toro the Bull appears at the beginning of Who Framed Roger Rabbit, auditioning with other cartoon cows at the Maroon Cartoon Studios for a part in a cartoon.
Toro has also appeared in several Looney Tunes games, such as Bugs Bunny Rabbit Rampage, where he is tricked by Bugs and runs into steel grinders, Bugs Bunny in Double Trouble, in the level "Bully for Bugs" (which itself is based on the cartoon of the same name), and Bugs Bunny: Lost in Time, in the La Corrida boss level. He also appears in Looney Tunes: Acme Arsenal as the boss of the level "Bully for Porky" along with Hyde Porky, in Looney Tunes: Back in Action: The Video Game where he is rampaging in the Louvre, and in Looney Tunes World of Mayhem as Lunar Toro, a Chinese lunar new year variant of Toro the Bull.
Toro appeared in the Looney Tunes Laff Riot test pilot before it was replaced by The Looney Tunes Show. It would have been his first appearance in a TV series. He also would have been Yosemite Sam's henchman.
