Twitch is a supporting antagonist in Pixar's 11th full-length animated feature film Toy Story 3. He is a male warrior insect and one of Lots-o'-Huggin' Bear's henchmen. He talks by using his mandibles and bears a resemblance to a moth.
Twitch is seen with the other toys from Sunnyside Daycare in the Butterfly Room when the toys have their first donation. Mrs. Potato Head meets him and feels his biceps after helping her when she had fallen, much to Mr. Potato Head's jealousy. Later that night, Twitch and the other of Lotso's workers enter a vending machine in Sunnyside Daycare playing poker using a See & Say toy.
Later on, he and the other toys find Buzz Lightyear out of the Caterpillar Room and seen capturing other toys under the Monkey's command. Sometime afterwards, Twitch and the other toys found out Chatter Telephone helped Andy's toys escape and break him as punishment. When confronting Woody and the rest of Andy's toys at the dumpsters, Twitch and Sparks present the broken Chatter to them. Later, after Woody reveals Lotso's past and true self, Twitch and the other Sunnyside toys are horrified when Lotso starts physically and verbally abusing Big Baby after he started showing remorse, and therefore do nothing when Big Baby retaliates and throws him into the dumpster. Twitch and the others are helpless as Andy's toys get thrown into the dumpster.
When Sunnyside is restored, Twitch is waiting to be played at in the shelf by a toddler. He handles Chunk who is tossed by one of the toddlers.
