A/N: before anyone get's the wrong idea, the rebirth of mothra trilogy is not canon to the heisei trilogy for a multitude of reasons. Like for example: The Cosmos and The Shobijin are not the same.
This is more on what if godzilla had existed in the universe in which the events of rebirth of mothra had played out.

Now, we would first need to events of the 1954 film to happen before any events of a second godzilla can happen since I'm using heisei godzilla for this. But past that, just how differently would the events of the films play out had godzilla been involved in the universe.
