Mr. Potato Head

Mr. Potato Head, or Potato Head for short, is a moody and cynical Mr. Potato Head toy. He appeared in Toy Story and Toy Story 2.

Toy Story
In the first film, after Woody accidentally knocks Buzz Lightyear out the window, he is quick to accuse Woody of being a jealous "toy-killer" and leads a mutiny with the other toys. He continues to admit Woody's guilt in the window incident, especially when he learns about Woody's disappearance. Later, Woody throws a string of Christmas lights from Sid's house to Andy's house; Slinky catches it, but Potato Head snatches it away and calls Woody a liar. Woody then tries to convince the toys to let him get back by pretending that Buzz is with him, but Potato Head remains suspicious of what Woody is actually doing. When Woody blows away the cover by exposing Buzz's severed arm, Potato Head furiously labels him as a "murdering dog" as the toys back away from the window, leaving Woody depressed and stranded in Sid's house. During the move to Andy's new house, after Woody tosses RC onto the street to rescue Buzz, Potato Head orders the other toys to "toss him overboard;" however, when Bo Peep reveals that "Woody was telling the truth," Potato Head realizes his error and compensate by holding onto Slinky's tail so Slinky could help Woody, Buzz, and RC back into the truck. At the end of the film, he is surprised to hear Molly receiving Mrs. Potato Head for her Christmas present.

Toy Story 2
In the sequel, after Al McWhiggin of Al's Toy Barn steals Woody, he is shown in a much more positive light by going on a mission with Buzz, Hamm, Rex, and Slinky to rescue Woody. During the mission, he is the fist to spot an idling Pizza Planet delivery truck nearby, in which he saves a trio of Squeeze Toy Aliens, which he adopts (quite reluctantly, actually, as he found them annoying but didn't want to disappoint his wife).
