The ancient deity of evil, Bagan, is back from his imprisonment, thanks to the help of Dogolas, an alien mastermind. While this duo appears invincible, three more warriors join the fight, including Godzilla's old friend Baragon. But even with the extra help, defeating these two masters of evil may prove more difficult than expected. New relationships will be formed, but old rivalries may get in the way.
Featuring Bagan and Dogolas, two Kaiju that never made it into a movie, as well as Baragon, Manda, and Komodithrax from the Godzilla 1998 animated series.
Godzilla has went through a mysterious portal that sends him back in time and gives him the ability to talk. He ends up back in the year 845 where he meets Eren Yeager, Armin Arlet and Mikasa Ackerman. Later on, he discovers that his old allies, Mothra and Rodan, have also ended up here. Now, it's up to them to save humanity, and wipe out every last titan that stands in their way. Or do they need to worry about something lurking among the stars.
