Sox is the latest addition to Pixar's cute animal roster — but where was Lightyear's furry whale call expert during the Toy Story movies? Lightyear is much more than a regular Toy Story spinoff. With Chris Evans taking over the iconic Space Ranger mantle from Tim Allen, Lightyear is based on the backstory Buzz believed was real when he first landed on Andy's bed — a tale full of aliens, spaceships, and sci-fi heroism. If Toy Story's Buzz is the action figure, Lightyear's is the movie character those toys might've been inspired by.
Lightyear's debut trailer introduced Buzz's pet, Sox — but only very briefly. Lightyear's second trailer is more generous toward robotic cat lovers. We see Buzz unboxing his mechanical companion for the first time, then hear Sox introduce himself as a «personal companion robot.» Sox's AI personality is blunt enough to tell Buzz how he regrets joining the adventure (shades of Rogue One's K-2SO there), but remains oblivious in his misguided attempts to help the Space Ranger sleep with «white noise.» Sox will be the comic relief in a film that's distinctly less comedic than Toy Story fans will be accustomed to… but his introduction creates a curious Pixar puzzle.

But if Lightyear is the movie Toy Story's Buzz came from, where's Sox? Any merchandise company
