Mr. Plotz

Mr. Plotz is the CEO of Warner Brothers of Animaniacs. He is extremely short with a short temper to match. Of all the cast, he hates the Warners the most. Thaddeus Plotz is at times one of the antagonists of the show, but he is sometimes shown to be not that bad after all.

Like Wakko, he has a fear of clowns, as revealed in "Clown and Out". In spite of this, "Clown and Out" also shows that he has faced his fear in order to do something special for the Warners. As revealed in "The Warners 65th Anniversary Special ", he worked in the front office of Warner Bros. Studios in the time of the Warners' creation. In "A Christmas Plotz", it is revealed that he took over the studio from his father by forcing him to retire. He is also sometimes known as T.P., Mr. Plotz, Plotz-y, and Plotz (all said by the Warners).

In Wakko's Wish, he became the tax collector, Baron Von Plotz, who briefly became King Salazar's mercenary.

He is voiced by Frank Welker.
