Warning! Spoilers ahead for Lightyear

While Lightyear is an action-packed look into the origins of Toy Story's iconic Space Ranger, Disney and Pixar essentially repeat Buzz Lightyear's character arc from his first origin movie. As seen in the animated feature that kicked off Disney's Buzz Lightyear of Star Command cartoon series, Buzz wanting to be a solo hero was a major part of that film released in 2000. Likewise, the framing devices for both the cartoon and Pixar's new Lightyear movie starring Chris Evans are also the same.

Released as a direct-to-video film from both Disney and Pixar to launch the Buzz Lightyear of Star Command animated series, Buzz Lightyear of Star Command: The Aventure Begins had Tim Allen returning to voice the main character he'd portrayed in the first two Toy Story movies. Already enlisted as a Space Ranger defending the Galactic Alliance as part of the Universe Protection Unit, Buzz Lightyear is one of Star Command's best. However, he loses his partner, Warp Darkmatter, who's seemingly killed in action. This results in Buzz's determination to work alone, uninterested in new teammates, or in receiving help of any kind. However, a nefarious plot from the Evil Emperor Zurg eventually convinces Buzz that he can't save the galaxy alone, resulting in him forming a new team with the three rookies the feature film introduces: the robot XR, Booster Munchapper, and Princess Mira Nova. As such, Team Lightyear's adventures were depicted in the subsequent cartoon series that followed, with Buzz now being voiced by Patrick Warburton in the actual series.
