Titans have always been humanities greatest threat, but what would happen if there was a threat that even the titans feared in the form of nature's most powerful weapon called, The King of the Titans. Disclaimer: I don't own Attack on Titan and its characters as well as any elements from the Godzilla franchise and Kaiju No 8, just this story and my oc. A/N: This story will follow the canon manga of Attack on Titan, however, with a few changes as a slight AU and it will also change the ending. This story will follow my oc that is also a Titan Shifter except he is not connected to the Nine Titans. He'll also have a harem consisting of Annie Leonhart and Mikasa Ackerman.
