Class 1A was involved in a fight, a real mission they had failed against a villian, this could be a villian if your choice or a custom villian, everyone was badly injured and barely conscious, the whole city around them was destroyed.

The villian laughs maniacally.

Izuku looked around do see buildings destroy and his friends injured badly, he grunt in pains, he starts too wonder...is there really hope- that's where you come in, you could could a celestial being or a person with a powerful quirk.
