While Rex feels excited about finally overcoming his frustration toward not being able to defeat Zurg previously, the alternate Buzz feels forlorn about losing his father, but it was revealed that he survived the fall.
In the post credit scene, Zurg's robot suit is shown drifting through space, undamaged, but seemingly inactive. However, the eyes on Zurg's robot suit suddenly power on, indicating that he survived the explosion after the fight with Buzz.
According to John Lasseter on the Toy Story 2 DVD commentary, as Andy's Buzz and the rest of the toys were making their way to the Pizza Planet truck, Ultra Buzz was carrying Zurg and said he was going to be burying his "father", implying that Zurg would have died from the fall.
As you may recall, in Toy Story 2 there is a scene in which Zurg tells Buzz he is his father, in a nod to Luke Skywalker and Darth Vader from Star Wars. But in Lightyear, it is revealed that Zurg is an older, alternate version of Buzz.
Beneath his mechanized suit, Emperor Zurg turns out to be none other than Buzz from another timeline, an older, embittered version (voiced by James Brolin) from a future that's figured out how to use Buzz's fuel to travel through time.
It is later revealed that Zurg is actually the 50-year future self of Buzz Lightyear, wishing to time travel back to the past to prevent his crew from ever landing on the planet.
A fan theory suggests that Boo from Monsters, Inc. grows up to be Andy's mom in Toy Story, but there are flaws in this theory. Pete Docter, Chief Creative Officer of Pixar, debunked the theory and explained that the Easter eggs in Pixar movies are not meant to impact the storylines of other films.
The decision to change Zurg's backstory was revealed by Lightyear director Angus MacLane in an interview with IGN. The filmmakers did try to work with the father element, yet they realized it distracted from the story as audience members would just be waiting for the reveal of his father.
Jessie. Buzz doing a Spanish romantic dance with Jessie. Buzz's relationship with Jessie is only hinted at the end of Toy Story 2 when Buzz became instantly lovestruck with her looks and her adventurous personality. Jessie immediately returns his compliments by describing him as the sweetest space toy she has ever met.
An alternate universe version of Emperor Zurg appeared in the Buzz Lightyear of Star Command cartoon series, where beneath the mask is an evil Buzz Lightyear.
There was a hidden reason why they keep referring Buzz Lightyear and their leader Zurg as B-Zurg ever time they speak, is because they can't pronounce Buzz's name correctly which foreshadows that Zurg is Buzz Lightyear when his first name has been scramble backwards after trying to say the B word first, while his last ...
So when artist Ken Mitchroney was tasked with creating Zurg for Toy Story 2, that little speech was all he had to go on. “I wanted him to represent all the different types of evil bad guys out there,” Mitchroney tells Inverse.
Super Strength: Zurg has demonstrated above-average levels of strength, able to destroy machinery with his bare hands, although it is unknown if this strength is natural or the result of his armor.
Although Toy Story 2 established that Evil Emperor Zurg was Buzz Lightyear's father, Lightyear retconned the relationship so that Zurg now has an entirely different backstory.
Although Buzz and his accomplices are successful in seeing off the threat of Zurg for now, it is revealed during a brief post-credits scene that the villain has survived the ordeal – and will no doubt be back for more. The stage is therefore very much set for Lightyear 2...
Beyond the in-universe lore, MacLane also said that each Zurg design was inspired by different aspects of Japanese culture. "[The Toy Story 2] one is a little more influenced by the kind of jumbo machinder Japanese toy," he said. "It has a little more of that kind of design language…
Woody. Woody and Jessie share a sibling-like relationship. Since meeting each other in Al's penthouse, the two share a close bond. The two are shown to have pretty heated arguments from time to time, but they deeply care for each other nonetheless.
It's revealed in the animated series that Andy's mom's last name is Davis, but also Emily's last name isn't revealed. So, in theory, both Jessie's owner and Andy's mom are named Emily Davis. While what happened to Andy's dad remains a mystery, Andy's mom's name could have secretly been answered.
Domee Shi debunked a popular fan theory that Boo grew up to be Abby Park from Turning Red. She did however, suggest that they could be related and was happy that people considered Boo Korean, at least partially.
Trivia. Lightyear's incarnation of Zurg is also an evil Buzz from an alternate future that has assumed Zurg's identity and traveled back in time to prevent the crash that marooned Buzz's colony on Tikana Prime even at the cost of damaging the space time continuum.
It is still a mystery to which species the evil emperor belongs. He appears to be some sort of cyborg or fully artificial lifeform, though this has never been confirmed (or denied).
