Sidney "Sid" Phillips is the main antagonist of Toy Story. Erik von Detten reprised his role as Sid again for the film as an adult, like the way John Morris did as.
Sidney "Sid" Phillips is the main antagonist of the 1995 Disney. He also destroys toys in many ways (exploding, burning, or in his "mad doctor" plays). In Toy Story, Sid is Andy's sociopathic 11-year-old next door neighbor (until Andy moved near the end of the film).
It's never been confirmed, but the garbage man in Toy Story 3 is widely believed to be Sid as an adult. The evidence is there in the skull T-shirt.
