Yakko Warner

Yakko, as his name implies, is the most talkative and quick-witted of the Warner siblings. Like his siblings, Yakko is an ambiguous dog-like cartoon character. He is the tallest and eldest of the three, about the same height as Bugs Bunny[citation needed] , and wears khaki pants up to his waist with a large belt. Like his siblings, he also has short black fur covering most of his body and white fur over his face, cheeks and eyebrows. His eyes are black and he has a small red nose, black ears, as well as a tail that sticks out through his pants. He was also seen with an addition of a green scarf in the movie. He also wears different attire in specific episodes, like "Roll Over, Beethoven", such as top hats, sashes, suits, etc.

It also seems as though he can store a variety of items within his pants, including a yak, much like Wakko does with his "Gag Bag". He doesn't seem to do this as much as Wakko. Yakko is the oldest of his siblings, though his age is never revealed in the show. According to Tom Ruegger, Yakko is fourteen.[citation needed]

Yakko is intelligent and well-read. Out of the three Warners, Yakko is the leader, taking charge of most situations, and Wakko and Dot look up to him. Being the oldest, much of the adult humor comes from him, though whenever it comes from anyone else, Yakko quickly pipes in with "Good night, everybody!"

Yakko and his brother Wakko are infatuated with the beautiful Hello Nurse. Whenever they spot her or another attractive lady, they react in an exaggerated manner, for example, howling like wolves and shouting "Hell-O-o, Nurse!" This is usually followed by them lunging into her arms and giving her a large smooch. They also add some kind of title to "Helloooo Nurse!" in some episodes. Like in "Cookies for Einstein" when they see a Swiss girl selling chocolate, Wakko shouted "Hellooooo Swiss Nurse Miss!" a play on the hot chocolate brand.

Among Yakko's abilities are a fluent understanding of the Japanese language and wielding two paddleballs at once. He is "the very model of a cartoon individual" according to the song of the same name in the cartoon "H.M.S. Yakko".

He is the 'guardian' of the trio, or the parental figure, as he seems to take charge in many situations, and acts generally in a father-manner/role model towards his siblings. However he can be seen to argue with or tease them like an older brother (typically) does as shown in the song "I'm Mad". However, when the need arises, he is loyal and protective.

He knows his limits and, while he will tease some people, he knows what to say and when to employ diplomatic charm to calm them down - or at least try to. This can be seen when he interrupts Dot's "I'm Cute" song, but notes that she is "awfully cute" when angered. He deeply cares for Wakko and Dot, as in Wakko's Wish, as well as some episodes in the series.
