Prologue
In the multiverse, there are currently four known universes: the Legend of Zelda universe, the Attack on Titan universe, the Tokyo Ghoul universe, and the One Piece universe. The former two and latter two have been connected due to special circumstances; certain beings have the power to create portals between the different universes.
This is a story of two more of those universes being connected.
In what we shall call the Bizarre Adventure universe is a man named Joseph Joestar. During his fight with the evil Pillar Men, a power is unlocked that connects his universe with another: the Hero Academia universe. However, he does not realize this until much, much later.
Decades later, he, along with his grandson, are searching for the evil Dio, and follow him to a portal that leads to a new universe - one filled with superpowers, heroes, and villains.
Their fate is bound with that universe, as well as Dio's. New threats will arise. New friends will be made. War will break out, and world-changing events will take place. And, somehow, a certain boy attending UA high will be right in the middle of it.
Follow Deku, Jotaro, Iida, Ochako, Joseph, Tsuyu, and many, many others, as they find themselves in a world ravaged by monsters, fighting for survival and the fate of both of their worlds.
A/N: It is time for a brand new story for me to write alongside my other two fics, Straw Hat Ghoul and To Hyrule and Back Again. I have started planning, and am confident in the story and its future. This prologue may seem confusing and short, but is crucial for understanding future events. Chapter 1 should be out very soon.
