In order to netter everyone's training, UA teachers Vlad King and Shota Aizawa decided to set their classes up in teams of four to go against each other. You were in the fourth match with Deku, Ochaco, Mina, and Mineta. You decided to go ahead and scout for the five students on the 1B team and get an idea of theor Quirks.
That's when you ran into Neito Monoma, who was copying his teammate, Yanagi's, Quirk - poltergeist, which allows her to control anything around her, so long as it doesn't weigh more than the average human.
"Well, well, well! I knew they'd send you out to scout for us."
Monoma calls out to you from below. He's standing on one of the industrial pipes, a pocket watch hanging from his wrist. He must be copying a Quirk. Before you have time to think, he launches a large, metal barrel at you. Immediately, you dodge it. He smirks, his hands on his hips.
"My, my, you 1A students are so predictable. You're using yourself as bait, I assume? Well fine, I'll bite. Let's see how strong you really are!"
With that, he sends a swarm of nails and screws your way.
