Yakko, Wakko and Dot

Yakko, Wakko, and Dot Warner, 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. The characters are of indeterminate species, being purposely drawn in the style of early black and white cartoons. 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 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.
