AN: This idea was bugging me for a while so i have decided to publish it here, due to the reviews of the readers, i guess i should move this one to the crossover section (I knew i should have follow my instinct from the start) oh well, with that settled, let's begin

Chapter 1: Avatar in the Superhuman World

Fire...

Air...

Water...

Earth...

Long ago, four nations were established, Its history, peace and harmony were maintained by the Avatar, the master of four elements...

However, everything will not last forever and so, the era of benders had come to an end and replaced by a modern world we know today...

Yet...the Avatar cycle still continues as the soul of the previous one reincarnate on a certain young individual, his name is...

A 4-year old kid was on his bedroom, he was currently unconscious on the bed, the light bulbs on the room were turned off and the only thing that gives light to the dark room was the moonlight on the window

"Izuku...dear" his mother said, she was beside him looking at Izuku's face in worry

"Please answer me...son" her mother, Inko Midoriya begged but he didn't respond

Flashback:

"N-No way...a-are you sure about that" Inko asked in disbelief, The doctor nodded at that

"Can you double check it again please, just to make sure" her husband, Hisashi told him

"We already did and the result was still the same...I'm so sorry but your son really is a quirkless one, therefore he can't fulfill his dream to be a hero" the doctor said, he really felt sorry for the kid since quirkless was a very rare on this world where quirked individuals and superpowers is a common thing

"I'm sorry Mr and Mrs. Midoriya...I'll be going then" the doctor said as he left the couple

"What should we do...how can we tell Izuku about this" Inko asked her husband

"We have no choice, sooner or later, Izuku will figure it out and the longer we didn't tell him, the harder it will hit him" Hisashi said

"But..."

"I know, it will hurt him a lot but...it's still better if we do tell him now, don't worry Inko-chan...We will be here for him and he was still our son, with or without quirk" Hisashi said

"..." Inko didn't respond as she just sobbed in her husband's chest

Few moments later after arriving home:

"T-That can't be...you're lying right" Izuku said in shock

"It's true son...and we're really sorry" Hisashi said calmly but inside, he and Inko were blaming themselves for Izuku's quirkless status

"That was...no this isn't true, you must be kidding" Izuku said, he was still in shocked state

"I'm really sorry..." Inko hug him tight

"No way...what about my dream" Izuku asked

"You just..." Hisashi grit his teeth, he can't even say it to him

"Huh"

"You just...have to give up your dream, Izuku" Hisashi told him

"!"

It hit the boy like a sledge hammer, his own dad telling him to just give up his dream to be a hero, even after all of those encouragement he said to him for more than three years and with just one single outcome, everything crumbled

Then an unexpected event happened, Izuku's eyes lit in white light and a powerful force were unleashed from him, Inko and Hisashi gasped in shock as they were blown away by the force

"WAHHHHHHHHH!" Izuku yelled as he continue to unleash a powerful force in form of wind

"IZUKU!" Inko yelled in horror

"SON!" Hisashi yelled, trying to reach him

"WAHHHHHHHH!" He continue to yell as the wind around him grew stronger then Izuku started to breath fire while yelling, shocking his parents

"WHAT!"

"D-Did Izuku...just breath fire"

"WAHHHHHHH!"

Then the fire accidentally grazed Inko

"KYA!"

"INKO!"

"!"

At the mention of his mother's name, Izuku eyes return to normal and the fire and air around him quickly disappeared and he passed out

"IZUKU!"

Hisashi, after seeing and being assured by Inko that she was fine, rush to his son, he tried to wake him up but no avail

"Hisashi, what happened back there" Inko asked

"I don't know...I just...can't believe that he..."

"But I thought he's quirkless, so how can he breath fire like that" Inko asked

"I wish I could answer them but I have no idea too, anyway let's take him to the bed so he can rest, we'll go see the doctor again tomorrow" Hisashi said. Inko reluctantly nodded

"Okay"

End Flashback:

"Izuku..." Inko said watching her son sleep like a cute little baby, she then started to sob and then she silently cried on his bed

"What in the world is happening to my son" she asked herself

Izuku:

"W-Where am I?" he asked himself, he just found himself in a green scenery, the sky was blue and there's a river on the side, everything was peaceful, Izuku roamed around but there's no one here

"Hello, is anyone here!" he yelled but no one answered, sighing to himself he decided to walk around and explore things until...

"So we finally meet..." a female voice said, Izuku jerked and immediately turn to see a very tall woman (Since he was still a kid), her skin was dark and has a shoulder length brown hair and a cyan colored eyes, she was looking at Izuku while smiling

"H-Hi..."

"Hello Midoriya Izuku..." the woman said

"H-How do you know my name" Izuku asked

"That's because I am your past life, we are connected" she answered him, Izuku was confuse at that

"W-Who are you by the way" Izuku asked her, the woman then pat him on his head

"I am Avatar Korra"
