Booster

Booster Sinclair Munchapper (voiced by Stephen Furst) – A huge red dinosaur-like former janitor from the agricultural planet Jo-ad (a play on the name of the Joad family, from John Steinbeck's The Grapes of Wrath). He has a big appetite and incredible strength, but is sweet and occasionally naive. He is in awe of Buzz Lightyear and has encyclopedic knowledge of his prior adventures.
