Yakko
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 woman (or Minerva Mink), 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 include 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 towards his siblings. However to Wakko and Dot, 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, which is seen in Wakko's Wish, as well as some episodes in the series.
