Sid Phillips

Sid Phillips is the main antagonist in Toy Story, alongside Scud. He is mentioned by Buzz in Toy Story 2. He also makes a cameo in Toy Story 3. He is the only person who knows toys are alive. He is voiced by Erik von Detton.

Personality
Sid is a young, bratty and somewhat disturbed 10-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 out heads or performing operations on them. He also destroys toys in many ways (exploding, burning, or in his "mad doctor" plays). Though despite this, he may have a lighter side, hinted in his dreams about ponies.

After his toys turned on him, he vowed never to hurt a toy again. Aside from this, Sid remained mostly the same (especially his love of heavy metal), and eventually became a garbage man.

Sid is not a true villain, being that he didn't realize that the toys are really alive when breaking them, but since this movie is in the point of view of toys, he can be considered an antagonist.

Toy Story
Sid is Andy's sociopathic 10-year-old neighbor (until the latter moved at the end of the film). Sid was introduced in the beginning of the film as a toy terrorizer when he exploded a Combat Carl with an M-80, with his toy-chewing dog, Scud, by his side. Andy's toys were surprised to see him back at his old habits so soon, assuming he got kicked out of summer camp early this year. Later that day, when Andy and his family went to Pizza Planet, Sid was also there. After playing Whack-an-Alien, the Crane Game caught his attention. After grabbing a Alien, Buzz Lightyear was put in view. He then went after him, getting not only Buzz, but Woody hooked onto his foot as well (Woody tried to save Buzz, but the aliens wouldn't let him).

After skating back home, with his new toys in his backpack, he was immediately greeted by Scud, whom he gave the alien to. Then, seeing his sister Hannah with her Janie Doll, he snatched the toy and ran up to his room, slamming the door in Hannah's face. He then pulled out his Pterodactyl toy as he played doctor for his "double-bypass brain transplant." After putting Pterodactyl's head on Janie Doll's body, he opened up the door and showed Hannah. Scared, she ran off to report to her mother. Sid threw the mutant toy onto the ground and ran after her, claiming that Hannah was lying. With Sid gone, Woody explored his room to search for a way out, but found the door locked and unable to escape. Trying to find another way out, he then discovered that Sid had taken toys apart and assembled them back together in weird combinations, much to Woody's horror.

The next morning, Sid tortured Buzz by spinning him on a drill bit (seen in a deleted scene), and then took Woody and threw him across the floor, pretending to interrogate him. Next, he opened up the window shade to let the sun in. He then took out a magnifying glass and focused the hot beam of light on Woody's forehead, until Sid's mom informed him his Pop-Tarts are ready.

Sid returned to his room later, with a rocket he had ordered in the mail, labeled "The Big One." He intended to blow apart one of his toys with the rocket for his own amusement. Initially, he was to blow up that "wimpy cowboy doll," but he couldn't find him (Woody hid under a milk crate). However, when he stepped on Buzz Lightyear's laser button, which activated the laser light-bulb, he chose to tape the rocket on Buzz, stating that he had always wanted "to blow a spaceman into orbit". Unfortunately for Sid, he was forced to delay the launch due to "adverse weather conditions at the launch site" when a rainstorm hit, giving Woody and Buzz time to reconcile overnight.

While trying to escape, Sid woke up and took Buzz outside to blow him up. Woody and all of the mutant toys planned a way to extract revenge on Sid and help Buzz before Sid destroyed him with the rocket. The toys all appeared out of nowhere and approached Sid, making him increasingly scared. Woody then told Sid to take care of his toys, because they would know if he did not. After seeing Woody come to life in front of his face, Sid screamed and retreated back into the house, frightened that the toys had come alive. Hannah then took pleasure in scaring her brother even more with her dolls after she discovered how scared he was.

Sid's rocket was ultimately utilized by Woody during the move to Andy's new house to help RC, whose batteries had been depleted, back into the moving truck as Woody and Buzz both went skyrocketing, during which Buzz freed himself from the rocket by opening his wings to tear off the tapes that bounded him to the rocket (as for the rocket, it climbed up for a few feet higher before exploding into smithereens).

Monsters Inc.: Laugh Factory
Sid made guest appearances in issues 3 and 4 of the Monsters, Inc. comic book mini-series, Laugh Factory, as the main antagonist, though his name is never actually given (as the monsters do not bother learning it from him). At the beginning of the third issue, "Toy Worry", he ducks into Boo's bedroom to hide from Sulley and Mike when they're pursuing him. We learn from Sulley and Mike that Sid has been using the monsters' door-traveling technology to break into kids' rooms and steal their toys. Afterwards, Sid escapes with Boo's Jessie doll, and Boo follows him into Monsters, Inc. to help Mike and Sulley capture him. Upon being caught and brought to the C.D.A., Sid states that he has been stealing the toys in an attempt to "save" the kids from suffering the same incident he did, but the monsters do not believe him. They have Sid thrown back to his home through Hannah's door.

In the next issue's story, Sid breaks back into Monstropolis and helps Randall Boggs and Mr. Waternoose escape from prison. They offer to give him the plans for their door-traveling technology (which Sid plans to get rich off of in his world) in exchange for him helping them get revenge on Sulley and Mike. They manage to capture the heroes along with Celia and Boo (the latter of whom stowed away with Sulley as he was coming back from his last visit with her), but the girls manage to escape back into the human world with Sid and the two villainous monsters pursuing them. Eventually, Celia and Boo manage to find another closet-door back to Monstropolis, where they lead Sid, Randall, and Waternoose into captivity by the C.D.A. At the end, Sid is again sent back home, with the monsters hoping that he has had enough of them now.

Toy Story 3
Sid appears in Toy Story 3, grown up and working on a garbage truck. He is seen twice in the film, the first time being as he comes to pick up the trash from Andy's house (including Andy's toys who were also in a bag and mistakenly got put outside by Ms. Davis, whom Woody hurries out to rescue without being seen). Sid is mostly heard scatting to music and is identified by having the same skull t-shirt that he wore as a kid, along with a yellow vest, goggles, a goatee, and a big set of headphones. He is seen again near the end of the film, after the toys escape from the incinerator at the Tri-County Landfill and hitch a ride on his garbage truck to get home. During his brief re-encounter with him in the first scene, Woody apparently did not recognize him as being Sid as he was more concerned about saving the others. In the second scene, the toys also didn't recognize Sid because their attention was focused on the garbage truck that would be used to take them home. His sister, Hannah Phillips, is not seen in this movie, nor is Scud for that matter. It is possible Scud has passed away at this point, given that this film takes place about 15 years after the first film.

Trivia

 * Sid is mentioned in Toy Story 2 during the journey to find Woody.
 * Terrence from the Cartoon Network series Foster's Home For Imaginary Friends seems to have been based on Sid, both appearance wise and personality wise. Also, Buford Van Stomm from the Disney Channel series Phineas and Ferb seems to have a very similar shirt to Sid's.
 * Sid also appeared in a Toy Story Treat short Woody's Nightmares. In one of the two nightmares that Woody had, Sid was laughing evilly as he had swapped the heads of Woody and Buzz Lightyear (the similar way he had replaced the Janie Doll's head with the Pterodactyl's).
 * It is said that Sid Phillips is inspired by a former Pixar employee who has been known to disassemble toys and use the parts to build strange creations.
 * Sid is ranked #26 in the Top 30 Disney Villains.
 * Sid's name may have been inspired by Sid Vicious, due to a nickname given to him during production: "Little Jack Nicholson" as Jack Nicholson played Sid Vicious.
 * In Monsters, Inc., Claws Ward runs out the door of a kids room on the scare floor. He states that the kid almost touched him. As he runs out, the "Kill'n Paul Bunyan and his Blue Ox of Doom" poster from Sid's room can be seen on the wall of the room.
 * Sid is one of the two antagonists to appear in a Pixar movie more than once.
 * It is unknown how he recovers from his toys-spring-to-life trauma. Possibly he forgets about it or dismisses it as his own hyperactive imagination.
 * It is likely that he reforms for the better, as his appearance is somewhat neater and is more hygienic, as his teeth are clean and even, in contrast in the first movie. The way he happily bangs trash bins and his garbage truck, as well as scatting to his heavy metal music shows that he enjoys his job.
 * Erik Von Detten returned to voice Sid in Toy Story 3. The fact that he is now older than he was when he did the first Toy Story movie had no affect on the character of Sid since he had also grown up.
 * Sid is the only human character in the Toy Story series who knows toys are alive.
