Todd Ianuzzi serves as a major antagonist in Beavis and Butt-head.
Todd Ianuzzi is a twenty-something hoodlum who is rude, arrogant, and violent. Beavis and Butt-head admire him and aspire to be included in his gang. Todd despises the duo and won't hesitate to beat them up. He will also take advantage of them when he needs money or a place to hide from the police.
Todd wears mirrored sunglasses and a mechanic's shirt with the sleeves torn off and his name on it. He has a tattoo on his right bicep of a flaming skull. The tattoo has an eye-patch clutching a knife between its teeth with a message around it reading Life Sucks. His blonde hair is cut in a mullet style. He drives a primer patched green Plymouth Duster often onto lawns, through garbage cans, and over Beavis and Butt-head's bikes.
- Originally, Todd was an idea belonging to the series' writers. They suggested him as a role model for Beavis and Butt-head. Todd was based on a teenage bully who terrified Mike Judge during his childhood.
- South Park villain PC Principal bears a physical and facial resemblance and has a similar personality to Todd.
