"In a world where Grimm, Danger Beasts, Monsters, and notorious villains run rampant, there are those who stand against them. Benders, Huntsmen, Heroes, people who have the power to fight them, for the sole purpose of defending the innocent. At least some of them. Other guys just want to prove how powerful they are, and push around people without powers. I learned that the hard way. My name is Y/n Tennyson. I'm 20 years old, and I am in possession of the most powerful alien weapons, in the universe. When I was little, people like Bakugo and Issei picked on me everyday, just because I was too powerless to do anything. So one day, I decided to drop out of Union Academy and went on a cross country road trip with my grandpa and cousin. Then on our first stop, I went out on a walk where a meteor fell out of the sky and crashed right in front of me. But, as it turns out, it wasn't a meteor, but a pod containing a watch that, once stuck upon your wrist, could turn you into any alien you want. Needless to say that my life went uphill from there. I traveled across the galaxy, saved it from blowing up. Fought a giant alien, AS a giant alien. Stopped a race from destroying the universe. Blew up my watch. Got a new one. Dated a tennis player, and broke up with her. Fought a giant alien, as a giant alien AGAIN, this time in Tokyo. Killed an interdimensional demon along with my archnemesis. And made friends with a Slimebiote named Skurd. Now me and my friends are unlicensed heroes who defend the world from destruction. Mainly because it's the right thing to do, but partially to show Union Academy what kind of hero I am now. And I can't wait to see the look on their faces."
