Emperor Zurg

Emperor Zurg is Buzz's arch enemy. He is voiced by Andrew Stanton.

Toy Story
Zurg does not actually appear in the first Toy Story, however he is mentioned by Buzz, who makes a reference to a Death Star from Star Wars Episode IV: A New Hope.

Toy Story 2
Zurg appears in two forms in Toy Story 2. He is initially seen doing battle with Buzz during the opening sequence (which is later revealed to be only a video game).

An incarnation of Zurg is later accidentally released by Andy's Buzz Lightyear in Al's Toy Barn. Believing himself to be real much like Andy's Buzz has done in the first film, he pursues after Andy's Buzz to destroy him. He seems to have followed Andy's Buzz across the street, into the entrance of Al's apartment that is an air vent, and up the elevator shaft as he is seen arriving atop the elevator when the Andy's Buzz and the other toys head back to the elevator after Al packs Woody and his Roundup gang into his case and leaves his room to head for the airport. Along with the rescue squad of toys is an "alternate" Buzz Lightyear action figure, also released from Al's Toy Barn, who also believes himself to be real. Both the "alternate" Buzz and Rex, a fan of the video game "Buzz Lightyear: Attack on Zurg", are caught with surprise by Zurg's unexpected arrival.

A showdown occurs between the "alternate" Buzz and Zurg atop an elevator, where Zurg uses his chief weapon (which appears to be a Nurf ball gun.) During this battle, Zurg reveals he is Buzz's father (a parody of the famous Darth Vader/Luke Skywalker ordeal from Star Wars Episode V: The Empire Strikes Back). As Zurg sets his gun to his highest level and is about to finish the "alternate" Buzz off, Rex, not bearing to watch the duel anymore, turns away, but his large tail hits Zurg, knocking him down the elevator shaft.

Zurg seems to have survived the fall as he and the "alternate" Buzz are seen playing catch and spending "quality time" together when the "original" Buzz and his rescue squad make their way out of Al's apartment. The "alternate" Buzz describes Zurg as a "great dad" as he rushes to catch another ball fired by Zurg.
