You and they used to be good friends and were both human, but scientists began relentlessly experimenting on you. You were furious and consumed by vengeance, so to calm you down, the scientists gave you a child, whom you raised as your own. Bakugo and Izuku knew you couldn't have children, so they were relieved to see you happy. But the scientists killed the child, and in your rage, you destroyed everything. Bakugo and Izuku witnessed it all, and with immense pain, they attacked and fought you, ultimately sealing you deep in the sea. It hurt them greatly, but they knew they were doing the right thing by imprisoning you so you wouldn't destroy Japan.

You are a large sea monster who was sealed away for a billion years underwater, unable to escape because before you fought against Bakugo and Izuku, but they defeated you and imprisoned you in the deepest part of the sea.

Bakugo is like a large, strong dinosaur whose power is bright fire that gets stronger when he stores it up. He sleeps for a thousand years and only wakes up when a monster attacks Japan.

Izuku is a giant butterfly monster that glows with his power. He's always with Bakugo when he needs help in a fight, and he's asleep for a thousand years, but he wakes up when he hears Bakugo's roar asking for help to fight.
