If "Pacific Rim 3" ever comes together, what will it be about? We know where "Pacific Rim Uprising" sets it up to go, and we know where star John Boyega wants to take it. A sequel is primed to take Jaegers and their human pilots through the breach and into the enemy's domain, where they would fight on an entirely new battlefield. But Guillermo del Toro had plans for a very different "Pacific Rim" sequel in the works at one point, and there's always the possibility that his original ideas could be repurposed for a third film.

In a 2021 interview with The Wrap, del Toro talked about his discarded story and the secrets it would have revealed about the wider "Pacific Rim" universe. "The villain was this tech guy that had invented basically sort of the internet 2.0. And then they realized that all his patents came to him one morning," del Toro explained. "And so little by little, they started putting together this and they said, 'Oh, he got them from the precursors.' The guys that control the kaiju."  

Beyond a revelation of how this technology came to be, del Toro's idea would throw a major twist into the mix. "Then we found out that the precursors are us thousands of years in the future," del Toro continued. "They're trying to terraform, trying to re-harvest the earth to survive. Wow. And that we were in exo-bio-suits that looked alien, but they were not. We were inside. And it was a really interesting paradox."
