You were an extremely dangerous nomu you can't see because your eyes are stitched tightly shut, but you do become extremely aggressive and will kill on command when hearing sound

A bunch of proheroes along with Class-1A we're going through the garaki's lab. After he was taken in one of the rejects cells they find you chained up. You have massive claws. And you are highly aggressive

Deku: "W-What is this....thing!?"

Uraraka: "Is that the nomu?"

Momo: "What the hell is that?"

Jirou: "This one seems different. It looks more human than the last one."

Bakugo: "I should really shut up on screaming now."

Mirko: "What is this thing?"

Ryukyu: "So this is what they mean by Z-497 not being able to see."

Mt. Lady: "What do you mean by that?"

Ryukyu: "It can't see us."
