Turning Red was released in 2022 but set in 2002, and Monsters Inc was released in 2001. In any Pixar theory, timelines are always the trickiest element, and the part where most theories like this could fall flat.
All this considered, it's not unbelievable that Turning Red fits into Pixar's shared universe by making Abby a teenage Boo. It was also theorized that the witch could time-travel, as she had a carving of Pixar's timeless Pizza Planet truck Easter egg. This theory carried some weight due to a wood carving in the witch's hut which resembled a familiar fuzzy face Sully. It goes that the witch in Brave is Boo grown up, and the witch's magic stems from Boo trying to find a way back to Sully and Mike using portal magic, similar to the doors in Monsters Inc. Upon the release of Bravein 2012, a new theory came to light regarding Boo. It's even thought that Boo is in Toy Story 4. Two potential playmates were picked out for their likeness to Boo one donning a pink headband and holding a cat plush toy, which audiences thought of as a reference to 'kitty' AKA Sully, and another playmate who had Boo's classic pigtails. Audiences believed that Boo was either Bonnie, the new owner of Woody and his gang, or one of Bonnie's playmates, subtly tucked away in the background of the film. But we’re getting several thousand animated years ahead of ourselves.Before Boo found her more official place in the Pixar theory, it was believed that she was in Toy Story 3. It’s in Brave, set in the Middle Ages, where moviegoers find a character that they first met more than a decade before in a seemingly unrelated film set several millennia in the future, at the far end of the Pixar timeline. The theory begins and ends with Brave, the studio’s 13th feature film and one that falls at the very beginning of the animated universe’s chronology as we know it. The Grand Unified Theory of Pixar is a long tale, spanning centuries, of a struggle for the domination of Earth among humans, animals with humanlike consciousness, and sentient inanimate objects-AI machines. (A longer version of this article originally appeared on Negroni’s personal blog. Negroni has condensed his original theory for Slate. Back in July, Jon Negroni went down an animated wormhole with his Grand Unified Theory of Pixar, an absurdly close reading of the studio’s canon that weaves together each of its 14 feature films to create a world that stretches several thousand years into the future only to eventually loop back upon itself.
