{ Todoroki's World }
It was a normal day in Todoroki's world but that doesn't mean nothing bad wont happen. Nobody but a few people knew it was going to be a bad day but they didn't expect it to be this bad.

" Three, Two, One,.... Uh, guys I don't think its worki---Ah!...BOOM!!"
That's how Todoroki's world exploded, just because the Boss in the hospital got his materials mixed up and they blew up the core of the world. Some people weren't lucky and died in the explosion but some are alive but they got blown into different planets. Just like Todoroki got blasted to Earth, the human world.
{ Deku's World }
On Deku's world it was a chain reaction that was the reason for his world's explosion. So when Todoroki's world blew up, some huge chunks of Todoroki's world fell onto Deku's world.

They had saved 10000 people out of 100000 people and Deku was one of the 10000 people. But some people had not put on their gear on time so... they couldn't breathe in outer space and died.
Deku was one out of thousands that didn't get stuck in space.
Some other people landed on other planets but only Deku landed on Earth, but he wasn't the only one who crashed into Earth on accident. There was another boy who was also sixteen, that crashed on Earth without anybody to talk to who would understand him and his powers.
