Sidney "Sid" Phillips is the main antagonist of Toy Story. He is a sadistic 13-year-old boy who blows up and obliterates toys just for fun. Sid has a little sister named Hannah and a dog named Scud.

In "War of the Villains," Sid was in the middle of destroying a combat carl when Brad Buttowski showed up, insulting him of being nothing more than a toy tormenter. Offended, Sid calls Scud to chase Brad off.

Later on, Sid would later try to blow up a Buzz Lightyear action figure, only to be distracted by Brad's secret weapon: Mad Jack. The Psychopathic Jack-in-the-Box scared Sid so bad that he swore off toy-tormenting for the rest of his life.
