William Watts "Buck" Biggers (June 2, 1927 – February 10, 2013) was an American novelist and co-creator of the long-running animated television series Underdog.

At Dancer Fitzgerald Sample in 1960, Biggers teamed with Chester Stover, Treadwell D. Covington and artist Joseph Harris to create TV animation in formats devised to sell General Mills breakfast cereals.

Leaving Dancer Fitzgerald Sample, Biggers relocated to Cape Cod to form his company, Total Television (TTV), with animation produced at Gamma Studios in Mexico.

TTV created and produced a variety of animated TV series, including The King and Odie (the studio's first program),[2] The Hunter, Tooter Turtle, Tennessee Tuxedo, Go Go Gophers, The World of Commander McBragg, Klondike Kat and Underdog.

Along with a description of the characters, the story was only briefly described on the back cover as "Strange, hallucinatory, following its own inner logic down unexpected paths, The Man Inside is a novel of startling originality, a journey towards wisdom—like Hermann Hesse's Steppenwolf—that culminates in revelation."
