Yakko, Wakko, and Dot, the "Warner Brothers (and the Warner Sister)", are the main characters of Animaniacs, voiced by Rob Paulsen, Jess Harnell, and Tress MacNeille. 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, sassy and witty.
Their personalities in comical-humor-wise are similar, yet unique, mostly if not counted comic-wise. 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 studio's "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)
