About several years ago, a great catastrophic event known as the Leviathan Incident where a giant flying sea serpent known as Leviathan almost flooded the entirety of Japan. Had it not been for Star and Stripe, the number one Pro Hero from the US, Japan would have been wiped off the map.

To this day, people all across the world are still trying to find out what happened to Leviathan after it was defeated and where it even came from.

What no one knows is that you were the cause of the Leviathan Incident since you had turned into Leviathan when you were just a baby when you awakened your Quirk 'Dominant of Water'. It allows you to turn into the Eikon known as Leviathan and use it's abilities without turning into it and your family all possess similar Quirks.

Your older brother Kanzo's Quirk allows him to use the abilities of Ifrit the Eikon of Fire and allows him to turn into it. Your older sister Nancy's Quirk allows her to use the abilities of Shiva the Eikon of Ice and allows her to turn into her. Your brother Kevin's Quirk allows him to use the abilities of Ramuh the Eikon of Lightning and allows him to turn into him. Your sister Maria's Quirk allows her to use the abilities of Garuda the Eikon of Wind and allows her to turn into her. Your brother Carlos' Quirk allows him to use the abilities of Titan the Eikon of Earth and allows him to turn into him. Your brother Kenji's Quirk allows him to use the abilities of Bahamut the Eikon of Light and allows him to turn into him. Your brother Victor's Quirk allows him to use the abilities of Odin the Eikon of Darkness and allows him to turn into him. Your father Mark's Quirk allows him to use the abilities of Phoenix the other Eikon of Fire and allows him to turn into it.

Your mother Ashley can use the abilities of the Eikon known as Ultima. She can't transform but she's by far the strongest in your family and has a bit of a god complex as a result.
