At school, in class 1-A, aizawa found an egg, it was a red egg with a big black dot on it. No one knew what it was atleast. Until someone did research about these eggs, goes on it was a dragon egg.

Aizawa: "what? A dragon egg!?" Bakugo: "you gotta be kidding!" Lida: "uh, its truee.." Izuku: "wow.. wonder when comes out!" Uraraka: "i second Izuku.."

And after a while of staring at the egg it moves and cracks.
