This is a list of characters in the Warner Bros. animated television series, Animaniacs.
Yakko, Wakko, and Dot, the "Warner Brothers (and the Warner Sister)", are voiced by Rob Paulsen, Jess Harnell, and Tress MacNeille respectively. Yakko (the oldest child) is a wise-cracking smart-aleck and usually acts as the leader of the trio; Wakko (the middle child) has a Liverpool accent, a huge appetite and a gag bag filled with tricks, and Dot (the youngest child) is cute and sassy.
Their personalities in comical-humor-wise are similar, yet unique, mostly if not counted comic-wise and are dog-like. In the show, the siblings often appear in other characters' skits, usually chased by Ralph the security guard; most other characters are confined to their own segments. They are usually referred to as the "Warner Brothers and the Warner Sister" if all three, though since one is female, the proper term is actually "Warner siblings". Their last name "Warner" is named after the real-life studios "Warner Bros." or "Warner Brothers". They were drawn in the "Warners Studio" supposedly their age from Yakko to Dot, oldest-to-youngest are labeled in age by who was drawn first, middle, and last; at least because the theme intro shows Yakko being drawn first, Wakko middle, and Dot last. The show usually follows these characters' zany skits, and usually portrays them to have low intelligence. However, this may only be internal whit and the ability to see the humor in every situation around them, never taking anything seriously. (They are regularly shown to be very clever and knowledgeable in many areas, usually causing events that should have been impossible to predict).
They are seen on occasion running across the set in cartoons that do not cast them, chased by Ralph.
Their creator, Tom Ruegger, called their species "Cartoonus Characterus".
Pinky and the Brain are an imbecilic white mouse and his genius companion, voiced by Rob Paulsen and Maurice LaMarche. The Brain is clearly the leader, and attempts to take over the world; Pinky is eccentric and unintelligent, but loyal to the Brain. In 1995, they were spun off into a series.
Goodfeathers are an Italian American trio of pigeons: Squit (gray), Bobby (turquoise), and Pesto (lavender), who were voiced by Maurice LaMarche, John Mariano and Chick Vennera, influenced by Ray Liotta, Robert De Niro, and Joe Pesci's characters in Goodfellas.
