I Am Izuku

I am Groot, literally

It starts as a young Izuku is looking to a young Bakugo

Izuku: w-why are you so mean Kaachan?

Izuku cried out as it's revealed he is trying to protect another kid

Katsuki: hah, don't try to be a hero you damn Deku.

Katsuki said as he started to attack the young green bean with his goons

Until a certain attack hit Izuku's head, as if it triggered something in his body

Izuku started screaming in pain, not from his attacks, but from his body shaping and turning

The once fleshy body of Izuku, morphed into one of pure wood and what looked like moss
(It's not letting me put images but... its Baby Groot)

Katsuki and his goons stopped

Tsubasa spoke up

Tsubasa: h-he has a quirk?

Katsuki looked to the kid he was just punching... and scoffed

Katsuki: your welcome you damn Deku, I made you awaken your quirk...

Izuku: I... am Groot? I-I am Groot? I AM GROOT!

Izuku said first asking what Katsuki meant then started freaking out from his voice, then saw his body

Tears started to form in Izuku's eyes, as he saw what he became, his bullies far gone... then the kid he saved walked up to him

Kinoko: h-hey... thanks for saving me... Izuku right? Shroom

Izuku nodded and looked to his hand

Izuku: I.... I am Groot...

Kinoko chuckled softly: no I don't mind what you look like, in fact... y-your kinda cute... shroom

Kinoko said with a blush

Izuku reached his hand out to Kinoko as to hug her as someone who didn't start beating him up and accidentally started making flowers on the tips of his fingers

Kinoko returned the hug a bit flustered: h-hey... so... what do you want to call your quirk Izuku?

Izuku stopped hugging the girl and pondered not realized that the flowers were still on his fingers, which caused Kinoko to pick them and smell them

Izuku: I am Groot?

Kinoko: o-oh. I'm sorry, I just thought...

Izuku: I am Groot, I am Groot

Izuku responded to the girl telling her that it's fine

Izuku: .... I am Groot?

Izuku asked what his quirk name could be

Kinoko: hmm... sounds pretty on the spot... hey, wanna know my quirk shroom? It's not that powerful of one but I hope to be a shroom hero in the future

Izuku: I am Groot?

Kinoko breathed in and out and produced some mushrooms from the ground, only two or three was growing though

Izuku: I am Groot

Kinoko: y-you think I'd make a fine hero? T-thanks... let's be heroes together! Ok Izuku?

Izuku nodded with a smile and hugged the girl before going home to his mom

A few .... several... years pass and Izuku and Kinoko stay in touch... mostly cause she's one of the only few to understand Izuku
