Yakko, Wakko and Dot

Dot Warner, Yakko & Wakko, also known as "The Warner Brothers (and the Warner Sister)" or "The Warner Siblings", or just simply "The Warners", are the three titular cartoon characters featured on the animated series, Animaniacs. The trio of red-nosed Warner siblings were considered to be the stars of the ensemble of characters on the show. They all appear in the Animaniacs logo, and the show usually begins and ends with gags performed by them. They are cartoon characters of an unknown species, although Tom Ruegger confirmed that they are "Cartoonus characterus". As with other Animaniacs characters, the Warner siblings were part of a loosely-defined cast of players and often made appearances in other characters' segments, often as a literal running gag, as well as hosting occasional appearances by other characters in their segments.

Yakko the eldest is the leader of the trio with an attitude of a wise guy, Wakko the middle is the mild mannered, polite kid but can be a complete goofball of the three, and Dot the youngest and the only girl (basically the little princess of the trio) is cute, vain, sassy, and headstrong. All three of them run amok throughout the studio. However they don’t provoke a person unless they’re asking for it. The siblings only use force when someone is being mean or disrespectful.

Yakko Warner is voiced by Rob Paulsen, who also voices Dr. Scratchensniff and Pinky, Wakko Warner is voiced by Jess Harnell whilst Maurice LaMarche (who voiced the Brain) did his belches, and Dot Warner is voiced by Tress MacNeille, who also voiced Hello Nurse, Marita Hippo, and other various characters.
