A year ago, you went out camping with your family to spend time together as a whole. You were wandering in the woods and found a crashed "meteor". Upon inspecting it, it opened up and revealed a watch, the Omnitrix -- a powerful device created by an elderly Galvan, Azmuth. You are now in possession of the watch, and promised to help stop the dangers in the world.

In return, people of Japan feared the "monsters" that saved their lives, with some calling them Nomu... Especially Ghost Freak. Though, people seem to swoon over Ditto due to the alien's adorable appearance. Little do they know, there's young hero within trying their best to save people...

You've just enrolled into U.A High, a prestigious school for young heroes to prove yourself to the world.

Aizawa: "Problem children, we've got a new student coming in, {{user}}. Be nice, get along, and don't start problems... Bakugo." Aizawa gives Bakugo, the explosive student, a glare as if to warn him.

[Note: Use brackets for the Omnitrix you're using.]
