The Slime Hero: Guu! - A BNHA x OC Story!

Prologue

We find ourselves in a pre-school playground, where most of the children are playing with each other in their own friend groups. In the far side of the playground, there is a group of kids comparing each other's quirks, as most of the kids have already gotten their own qurrks.

"Whoa! That's such a cool quirk Bakugo!" 

"Yeah! With a quirk like that, you can easily become the number one hero!"

We hear the group of kids gawking over one Katsuki Bakugo's quirk, who had just recently gotten his quirk earlier during class time. 

"Hey Ito, what's your quirk?" 

The kids all turn their attention to a black haired, dark skinned child with yellow eyes, who was currently walking towards one of his friends, he was one of the handful of kids who still hasn't manifested his quirk.

"Um, I don't know yet, but it should manifest pretty soon..." The boy said quietly.

"Yeah whatever, but don't get your hopes up, whatever you get it's probably gonna be useless compared to mine!" Bakugo said, while generating tiny explosions out of his hands.

"Oh, ok then..." Ito said disheartened, what Bakugo said was pretty mean, especially to an aspiring hero like Ito, he just wanted to be a great hero who saves people with a smile, like his friend Izuku Midorya.

Ito walked away with his head facing towards the floor. He looked around the playground, searching for his friend Midorya. He found Midorya playing on his own in the sand pit, he then joined Midorya, looking visibly sad, which didn't go unnoticed by the green-haired boy.

"Hello Ito, what's wrong?"

"Hey Izuku, I'm fine, but Bakugo said that if I ever get my quirk it was gonna be useless..."

"Don't worry Ito, I'm sure that your quirk will be great! And when I get my quirk we can both be heroes!"

Ito chuckled at his friend's response, he always had a way to cheer him up. His optimism was something Ito admired, he wished he could be as optimistic and determined as Midorya, he was always very shy and quiet. They had met a year earlier at the park when both their mothers became friends. Similarly to Izuku, Ito's mom was a single parent, his father had died a year after his birth in a surprise villain attack.

"Thanks Izuku, you always know how to make me smile."

"Don't worry about it Ito, that's what friends are for!" Midorya said, flashing one of his signature million-dollar smiles.

RRRIIIIIIIINNNNGGG

The bell signaling the end of recess had rung and everyone was getting up and getting ready to head back to class.

At that moment Ito suddenly felt very numb, like his whole body was seizing up and shaking. Midorya took notice of this and turned to see his friend.

"Ito, what's wrong?"

Suddenly, Ito started melting into a magenta-colored puddle of slime, it didn't hurt but it felt like pins and needles being continuously poked and stabbed all around his body. 

"OH MY GOSH ITO WHAT'S GOING ON!" Izuku's yell was heard by one of the teachers, who quickly ran over to investigate.

"Midorya what are you yelling about?" She then noticed Ito, who was currently only an upper torso and head sticking out of the ground.

His face was droopy and changing into the same color as the slime puddle beneath him, his arms were reaching out for help, since he didn't know what was happening, and they were dripping slime into the ground
