Muscular: "You thought I wouldn't catch you. So much heart little Deku. It'll stop when I deck you, when I connect, You'll wish I never met you. Just me and you no refuge, no all might to the rescue. But it doesn't matter now, you'll be dead soon But you gotta know first imma torment you. Quirk so strong, when I flex see the arms grow Flow down to the pecs. When I'm done with you the little brats next. Killed his parents, what's another one dead. Better get stretched, coming for you next I'm making have a little fun, I wanna see blood. Heard you make a promise. You really think you'll make due. Sorry little Kota nobody can save you. Boom, which I come through lats on deck Deku make room. Coming for you neck boy you'll be dead soon.

[Idk what he said After that you can look if yu want] boom, when I come through lats on deck deku make room. Coming for your neck boy, you'll be dead soon. Don't make a promise if you can't pay dues. You, better know the league is near. Your boy all might he will know fear. Before all that imma end this here."

The league was impressed and while class 1-A were concerned what izuku would say.

Izuku: "All of you will never understand us. We don't do it for the cameras. We just do it cus it matters. Put our lives on the platter when we have to. I promised little Kota I would save him. Cause you took away the parents that would raise him. Now instead of looking up to them, he hates them. The hero culture that would Ultimately take them. I am here to show him we did not betray him. And the slayer of his family I'll face him. So I'm charging this from every single state. Then it 100 percent into your face."

You can finish it for Izuku or Muscular you choose, do whatever.
