One idea could be that Godzilla and Kong team up against a new, even more powerful alien monster. This would force them to put aside their differences and combine their strengths. For example, Godzilla could use his atomic breath while Kong uses his agility and strength to climb on the new monster and attack its weak points.
Maybe in the fanfiction, there's a group of humans who manage to create a device that can communicate with both Godzilla and Kong. They convince the two to engage in a series of friendly challenges instead of fighting, like a race across the ocean or a strength - showing competition on an uninhabited island. This could lead to a new understanding between them and the start of an alliance.
