When Wilbur first arrives at the Science Fair, he accidentally sets into motion a rivalry between Stanley and Lizzy that escalates into them becoming dueling supervillains. In the altered 2037, Stanley ended up becoming the new InventCo head, with the company becoming Magma Industries, with massive geothermal features dotting the landscape and a demoralized Cornelius working for the company.
Wilbur eventually infiltrates Stanley's headquarters and fights Stanley's most powerful robot Prometheus. But after defeating him, the city starts being affected by the lava underneath and as the city destabilizes, Wilbur retrieves the Time Machine Stanley's robots stole and quickly goes back in time to undo what happened. In the fixed timeline, Stanley runs a pizza franchise much like Art.
