The Day the Monster Changed

Chapter 2 - Suddenly Back To 3 Years Old

3rd Person POV:
After that troublesome morning, the whole class 1A and their teacher Mr Aizawa, gathered in the room where a just-awakened green head boy sat on his bed. Recovery Girls sat next to him on a chair, and as everyone settled down she turned around and began speaking:
"So, I can't see anything going wrong with Midoriya. He's breathing normally, his blood pressure and pulse is normal, and basically nothing has changed. He's fully healthy. I think the villain was just bluffing for some reason." She finished and touched Izuku's forehead for the 100th time in that hour.
Aizawa sighed in relief.
"Ok that's one less thing to worry about. Is he good for lessons today?"
Recovery Girl nodded. "Yes, he's fully healthy. Are you feeling ok dear?" She asked turning around to Izuku who was already getting out of the bed. He turned to her and nodded with a smiled.
"Yeah! I don't think the villain did anything. The back pain is gone and I feel normal." He shrugged. Recovery Girl still seemed suspicious because what idiot shoots their quirk at an enemy and doesn't cause anything at all to them?
Nevertheless, the whole class headed back to their classroom as well as Izuku, and class started as normal.

It went normally throughout the whole morning, recess, middle session and lunch. On the last period, Aizawa went in like normal, and started class.
"Get out your hero notebooks we will be studying the safety rules of a hero again because last week someone from a class below from the hero course forgot this and did a mistake in their practice exam." Aizawa shook his head in disappointment and started writing things on the board. Halfway through the lesson, Bakugo suddenly stood up.
"Oi caterpillar I'm going to the bathroom." Bakugo said more like a statement but Aizawa sighed and nodded.
"Ok you can."
Bakugo went out and everything continued as normal until....
"AAAHHHH!!!!" A scream was heard. Aizawa sharply turned around and saw Izuku standing up, clutching his head, eyes wide. Then he started glowing purple and... shrinking. Suddenly the glowing stopped and everyone looked at the little 3-year-old boy standing next to his desk, gaping around. Though soon he started sobbing and then crying.
Aizawa furrowed his eyebrows but watched from afar like a hero who knew the safety would. But the other students obviously didn't because they all ran up to little boy and started asking him questions.
"Waaaa mommy!! Get away you scawy peopleee! It hurtssss!!! Mommyyy!" Izuku cried and wailed. Aizawas mind clicked then. He went back to the age of 3, which means he only knows some pro heroes and... his one friend Bakugo.
"Kids get aaay from him now! Kirishima get Bakugo hurry up! Yaoyorozu get Recoverg Girl immediately!" Aizawa yelled and everyone immediately scurried away while Kirishima and Yaoyorozu ran out of the classroom.

Aizawa then walked up to the crying boy and kneeled infront of him.
"Hey Izuku do you know me?" He gently asked as everyone gasped at the gentleness.
"Y..yeah pr..pro hero Er..erasure h..headdd... m.. I want mo...mommyyy! It hurtsss! Everything huuurtttss!!" He continued crying and wailing. Aizawa sighed.
"Don't worry kid, we're all friends calm down."
But Izuku kept on crying and pushing back into the wall in an attempt to get away from the "scary people".
Suddenly the doors burst open and a very angry Bakugo stepped in.
"WHAT THE FUCKING HELL AIZAWA!!! I WAS ON THE FUCKING LOO WHEN THE SHIT CAME IN AND YELLED AT ME TO COME BACK!!! THE FUCKING HELL Happened..." he trailed off as he found the subject of all the commotion. A crying little green head boy, who looked scared out of his life.
"Bakugo, Midoriya turned into a 3 year old and he has his 3 year old mind. He only knows his mum, you and some pros, but I can't calm him down. Please try." Aizawa asked him calmly. Bakugo glanced from the toddler to the pleading teacher, then the awkward class then back to the crying toddler who seemed to have not yet noticed the similarity of the younger and older Bakugo.

Bakugo sighed and slowly started walking towards the boy who then backed away, still clutching his head in visible pain. Aizawa quickly moved out of the way.
"Hey hey calm down. It's me Kaachan, except I'm big now see?" He whispered as everyone watched in shock. Izuku stopped crying and seemed to be examining the boy who was kneeling infront of him.
"K..Kaachan?" He sobbed. Bakugo nodded and sat crisscross infront of the boy.
"Don't worry it's me, can you see the similarities? I'm just an older version of your one." He whispered as Izuku seemed to calm down and nod.
"K.. Kaachan!" He then screamed and ran over to Bakugo and hugged him. Bakugo squeezed him and patted his head.
"Shh calm down." He said as he thread his fingers through the green soft hair.
"K..Kaachan the.. the scawy people... they... scawy..." the boy sobbed as Bakugo kept whispering reassuring words and petting his hair.
"It huwts K..Kaachan it huwwtsss." The boy sobbed and Bakugo reassuringly patted him head.
