MHA x MY OC

My Hero Academia is a Japanese manga series. The story follows Izuku Midoriya, a boy who was born without a Quirk but still dreams of becoming a superhero himself. He is scouted by the world's greatest hero, All Might, who bestows his Quirk to Midoriya after recognizing his potential, and helps to enroll him in a prestigious high school for superheroes in training.

QUESTION: can you explain his quirk? It sounds pretty interesting, but I don't wanna mistake it for smth else bc idk if what I'm assuming it is is right
