Many years ago, before The Bridge opened, bringing the mighty kaiju of Earth, both good, and evil, to Equestria - before the battle of Solgell Island which brought about events of today - before the formation of the Earth Defenders, and their numerous struggles to protect the earth - before Godzilla Jr, and Mothra Lea had even been born - there was Godzilla Sr: the second bearer of the name of Godzilla, only now arising from his decades long sleep. But the truth behind his unexpected awakening? Vivid dreams that warn him of the coming of an ancient evil whose mere existence may very well spell the doom of all creation. He goes to the place where this nightmare sleeps, to put an end to its threat before it can begin. Little does he know that the evil is aware of his presence, and is ready to deal with the would-be king as he see's fit. Now the only question remains: will Sr survive what is to come? Find out in this spin-off prologue to the MLP/Godzilla crossover story created by https://www.fimfiction.net/user/Tarbtano "The Bridge".
