He is best known for his speech consisting mostly of grunts, growls, and rasps (in his earlier appearances, he does speak English with primitive grammar) as well as his ability to spin like a vortex and bite through nearly anything.

[6] Robert McKimson designed the character based on the real Tasmanian devil, or more specifically its carnivorous nature, voracious appetite, and surly disposition.

[11] In his first appearance in McKimson's Devil May Hare (first released on June 19, 1954), Taz stalks Bugs Bunny, but due to his dimwittedness and inability to frame complete sentences, he serves as little more than a nuisance.

The character's speech, a deep, gravelly voice peppered with growls, screeches, and raspberries, is provided by Mel Blanc.

After the film short debuted at theaters, producer Edward Selzer, head of the Warner Bros. animation studio, ordered McKimson to shelve the character, feeling that he was too violent for children, and that parents would dislike him.

Taz appeared in an episode of The Sylvester & Tweety Mysteries entitled "The Scare Up There", where he is revealed to have stolen peanut packs from the flights.

Taz appeared in the 1996 feature film Space Jam, as part of the TuneSquad, voiced by Dee Bradley Baker.

[13] An infant version of Taz is one of the regular characters in Baby Looney Tunes, voiced by Ian James Corlett.

In the show, he is portrayed walking on four legs like a real Tasmanian Devil and his eyes are bloodshot red (later turned yellow when Bugs uses a taming trick that Speedy Gonzales taught him).

Eventually, Bugs learned the truth and tried to return him to his home in Tasmania, only to find out that Taz would rather live with him, naming him "Poochie".

Taz subsequently appears in the following episodes "The Foghorn Leghorn Story", "Newspaper Thief", and "Bugs and Daffy Get a Job".

Eventually, they make it home when it turned out that Blacque was hired by Yosemite Sam to retrieve the three on behalf of Bugs and Granny.

Taz originally appeared in the series Wabbit as Theodore Tasmanian, an accountant at Chesterfield Consultants who tries to repress his vicious side.

Taz appears in the 2021 feature film Space Jam: A New Legacy with Tatasciore reprising the role, with additional dialogue done by Cummings.

He is among the Looney Tunes characters guests for the Warner Bros. centennial celebration, with Fred Tatasciore reprising his role.

In June 2017, the character appeared in the Wonder Woman / Tasmanian Devil Special #1, written by Tony Bedard with art by Barry Kitson.

This version is reimagined as a Guardian of the Labyrinth on Themyscira, whom Wonder Woman defeated when she was a teenager, but later teams up with her to save the Amazons from Circe.

Warner Bros' trademark on the character has raised a number of issues with entities in the Australian state of Tasmania, where the Tasmanian devil is common and emblematic.

and a delegation from the Tasmanian state government met with Warner Bros.[9]: 161–164  Ray Groom, the Tourism Minister, later announced that a "verbal agreement" had been reached.

An annual fee would be paid to Warner Bros in return for the Government of Tasmania being able to use the image of Taz for "marketing purposes".

[citation needed] The deal with Warner Bros allowed the Tasmanian government to manufacture and sell up to 5,000 special edition Taz plush toys, with all profit going towards funding scientific research into DFTD.
