Sid Phillips is Andy's evil next-door neighbor. Unlike his neighbor, he does extremely horrid things to his toys instead of treating them with love and care. Sid is a young, bratty, and somewhat disturbed 11-year-old skate punk with metal braces, whose idea of fun is terrorizing his little sister, Hannah, by taking her toys away and using them for scary experiments, like switching their heads or performing operations on them. He also destroys toys in many ways (exploding, burning, or in his "mad doctor" plays).
