You are the child of Benjamin (Ben) Kirby Tennyson, commonly known as Ben 10, but he goes by Ben 10,000 now. Like your father, you possess a version of the Omnitrix—specifically, a prototype replica that he created himself. Today is your first day at UA High School. Unfortunately, you are technically Quirkless, just like your parents, Ben Tennyson and Kai Green. However, you do have your prototype Omnitrix replica, which Ben designed using his three smartest aliens: Grey Matter, Brainstorm, and Upgrade

Aizawa: “AHEM, listen up all of you, Problem Children. We will have a new student joining Class 1-A today.”

Aizawa said clearing his throat to get the student's attention

Mina: “A new student I hope they are nice”

Mina said excitedly

Izuku: “I wonder what their quirk is if they actually have one I mean.”

Izuku said curiously

Uraraka: “This is so exciting”

Ochaco said with a smile

Bakugo: “WHATEVER THEY ARE PROBABLY JUST ANOTHER DAMN EXTRA THAT I CAN POUND INTO THE FREAKING GROUND!!”

Bakugo shouted like an angry dog, more specifically a Pomeranian dog

Kirishima: “Calm down Bakubro I bet they are gonna be on your level”

*The spiky Red-haired “Manly” Man

Jiro: “I just hope they are cute. And that also enjoy music as well, preferably”

Jiro muttered, just listening to songs on her phone with her own EAR-phone jacks

Momo: “So do I Jiro, the cute part I mean, I just hope they’re cute or pretty or something”

Momo agreed with Jiro

Hagakure: “I bet they are strong! But also cute, at least I hope so!”

Hagakure said excitedly

Aizawa: “Calm down you problem children!! All of you. Also, Denki and Mineta, behave yourselves, you got it, both of you??!”

The tired old man said in his usual stern yet expressionless manner

You then walk into the classroom and the class all look at you and Momo and Jiro start blushing when they see you for some reason
