Train Now, Learn Later

(Age: 4-5)

During Izuku's first year at the Martial Arts School, he had learned that before he could just learn fighting skills right away, he would have to vigorously train for a year straight to prove loyalty to the dojo and so you won't dishonor them by using your skills for violence.

Izuku didn't have to worry about the weights at home because the sensei provided him a daily regiment that would strengthen his whole body and the dojo even provided weights.

-His mother got a refund immediately after learning this-

(Flashback)

"Now young Izuku, like any member of this Dojo, before you learn anything...Are you willing to undergo a one year transformation!" The sensei said showing the most devious smile to mankind.

He was thinking of how perfect he could mold this child to becoming a beast, it's always best to start off as children but even children who start martial arts never finish not knowing that your potential is infinite when you start from youth.

He could see the best in everybody, it was literally his quirk which allowed him to assess people's potential by the color of their aura and everybody had a aura, white being the weakest. But when he saw Izuku, there was nothing which meant he couldn't even see how high his potential went.

He knew he could even be training another future Pro Hero which is an extremely honorable achievement for a Dojo.

Izuku shook his head crazily, excited to see the motivation behind the man's eyes when it came to training to become stronger.

"Good...Then kid let the training arc begin!" He said copying what Izuku did earlier and did a fist pump in the air.

(Flashback End)

Here we could see Izuku, along with other new students running around the Dojo (Which is the size of a basketball court) in laps and they had to 50 around the Dojo.

The sensei, as cruel as he was even made them where weighted gi but only put as much weight as each student could handle. Izuku's gi weighed 10 pounds in total.

The training was so cruel that even after doing 50 laps, the students then had to position into frog jumps around the Dojo 50 times and end it off with 50 squats.

Izuku was just barely making it but he would think about what the doctor said to him and thought to himself, 'I can't afford to fail...I have to work harder than ANYONE ELSE!'

'This is a strong batch of newbies this year around...and yet that four year old is putting in more work than any of them...Trying to be lazy and lighten up your training is only cheating yourself, Impressive' The sensei analyzed silently in his mind.

(One Year Later)

"In the span of a year, only two of you is left remaining...I'm proud of you both especially since usually only one or zero survives this test.

Here are your white belts...your first trophies of honor" The sensei said awarding both Izuku and another teenage boy who endured the one year of pain.

Izuku's muscles were extremely cut and his body was chiseled all around. His muscles weren't bulk either, they were still lean but showed an extremely strong appearance.

Although he was five because he had gotten taller and was extremely built now, some would even mistake him for being eight and even his mother was proud to show off her son to her friends.

"You two can now stand in line along with the other warriors but not only that but scholars as well" He said to the two newest official members of the Dojo. Izuku and the other boy got in the line at the end and all the students stood up straight with their hands to side.

"Now we learn how to fight!" He said getting a horse stance position and throwing a fist, "KAI" he yelled as his punch sounded like it cut through the wind.

"Before anything...you must learn how to punch!" He said with a smile
