Theodore "Tobey" McCallister

Theodore "Tobey" McCallister III is a young villain in the educational TV show WordGirl. He is about the same age as Becky Botsford (who is also WordGirl) because they are often shown to be in the same class. Tobey is a boy genius that specializes in building enormous robots. His robots seem to be mostly for destructive purposes, but they have shown a wide array of abilities, such as food-making, cabin-building, checker-playing, painting, competing in athletic events, etc. Tobey doesn’t seem truly evil; rather, he comes across as reckless and mischievous. Often, his plans are foiled by his malfunctioning robots

Tobey has a obssesive crush on WordGirl - though he would never admit it to anyone else and has argued more than once to the contrary - and often concocts michievious and destructive plans simply to impress her or win her heart. He often demands that if he manages to defeat her with his robots, she must tell him her secret identity or go out for ice cream with her. He posesses a scrapbook with WordGirl news clippings and other miscellanea. Though WordGirl and Tobey argue a lot, they occasionally show that they have some compatibility, such as in the episodes "Have You Seen the Remote?" and "Department Store Tobey", and even though she will not say she had a good time with him in the former, she will not admit she didn't, either.

Tobey is played by comedic actor, Patton Oswalt.
