Lots-o'-Huggin' Bear

Lotso (full name Lots-o'-Huggin' Bear) is the main antagonist from the film Toy Story 3. He first appeared through a Cameo in Up.

Role in Toy Story 3
Lotso is first introduced greeting Woody and the gang, and then showed them around Sunnyside. He put the new toys in the Catterpillar Room, knowing that the toys there are treated with abuse by the younger kids. When Buzz Lightyear came to Lotso and his men asking for them to be moved, Lotso denies Buzz's demand and resets him to his demo mode, making him think he was a real space ranger again and manipulated him to be his henchman. He made Buzz kidnap his friends and lock them up, with Mr. Potatohead being put in "The Box". Woody, who had escaped Sunnyside earlier, saves his friends and formulates a plan to escape Sunnyside. When they tried to escape, Lotso shows up, and Woody reminds him of his old owner, Daisy. Mad that Daisy replaced him with another Lotso, he came to Sunnyside with Big Baby and Chuckles the Clown. Lotso and Big Baby rose to power and made the daycare a toy prison, while Chuckles was taken home to Bonnie's house. He, along with Andy's toys, was taken to the city dump and was almost killed before being saved by Woody and Buzz. However, he betrayed them and left them for dead. He was later found by a garbage-man who tied him up on his truck with a few other toys. He was last seen with one of them telling him to "close his mouth."

Trivia

 * Lotso was first spotted underneath a girl's bed in Up when Carl Fredricksen's house flies past her window and it was later comfirmed that he would be a new character in Toy Story 3.
 * When the toys are saved from the incinerator, Hamm and Slinky want to get back at Lotso for leaving them to die, but Woody tells them he's not worth it. This may be Woody remembering what happened between him and Stinky Pete, only this time Woody is letting Lotso learn the true meaning of playtime on his own when the garbage man finds him and ties him to the front of the truck.
