Buster Bunny (voiced by Charlie Adler and later John Kassir) is the leader of the Tiny Toons gang, a street-smart, blue and white male rabbit who has to deal with the challenges of a tough school curriculum, the machinations of rich kid and local bully Montana Max, and the advances of crazed and ditzy animal lover Elmyra Duff. Like Babs, he will do anything for a laugh, though he is marginally more sane and calm than his female counterpart.
Buster's parents, like many of the main characters on the show, have never been seen on screen. It is known that Buster does live with his mother however, because in Tiny Toons commercials, she has been referenced and has even been spoken to on the phone, mostly as a way to tell Buster that she was on her way home when he was having a party.
Buster has an extreme fondness for Bugs to the point of often imitating his mentor, such as using Bugs' "slap dance" technique from Bully For Bugs (though with considerably less success). Although cool and collected for the most part, there are instances where other characters will get the better of Buster, or some unfortunate mishap will befall him, unlike his mentor Bugs, who for the most part was always on top of his game.
It is shown in "Buster and Babs Go Hawaiian" that Buster doesn't like riding on airplanes because he gets motion sickness. There he tried to persuade the script writers to make a rewrite regarding his dislike of air travel. Because they refused, he had no choice but to accept it.
Buster's outfit is just a red shirt and white gloves, looking similar to Reader Rabbit's outfit. He wears no pants, which brings up the question implied in "The Looney Beginning" when he asks his creator for some clothes "for the censors". His body is light blue and white.
Like their adult counterpart, Buster (and at times along with Babs) begin any attempts at mischief with, "Of course you realize, this means war." However, in order to make the line his own, Buster then adds, "Buster (and Babs) style!"
Buster's solo end tag alone (spoken without Babs) is: "And that's a wrap!"
Buster was the last and hardest voice role to cast. Buster's original voice actor was Charlie Adler, of whom Tom Ruegger said, "Sometimes he went too gravelly and over the top, but brought a great deal of energy to the role". Steven Spielberg and other producers did not want Adler, but Ruegger and voice caster/director Andrea Romano fought for him. When Adler landed in the role he said in an interview, "This is the first time in 30 series I have been in, that I'm having the best time of my life working". During Season 3, when they started production on Animaniacs, Adler was disappointed that he didn't get a recurring character in the new show, while minor Tiny Toons actors like Rob Paulsen and Frank Welker from Tiny Toons were given main roles. He and his agent sent angry letters to Ruegger and other producers, claiming that his treatment had been "shabby" and that he was going to leave the show.
When Adler dropped out, the studio still had a handful of episodes to record, so they re-cast the role of Buster with John Kassir. Kassir's voice was slightly different than Adler's: Adler's voice had been more gravelly and rough, whereas Kassir's was smoother. Kassir finished the last 10% of Adler's lines from "The Horror of Slumber Party Mountain". He performed Buster's voice in "The Return of Batduck" and "It's A Wonderful Tiny Toons Christmas Special" in 1992; in 1994 and 1995 he reprised the role for "Night Ghoulery", and "Tiny Toons Spring Break Special". For the promos on Kids WB, Buster was played by various other voice actors, such as Billy West.
