Michael's childhood with his parents Aika and Logan was a happy one, he may have been annoyed by their constant babying, what room did he have to complain when he was really a baby?
He knew they were just trying their best to raise him the best they could, he also found out that while his family couldn't be considered a very rich high class family, they were pretty close, with relations to the Water hose duo through his mother, he was visited by them fairly regularly, they didn't seem to be married, but seemed to be very close, maybe going out at this point in time.
Michael had never used his heat vision since the day he was born, making his parents mistakenly think he was simply unable to use it when he was not in extreme emotional turmoil, at least not until he would hopefully manifest his full quirk at four years old, so they payed extra attention to his emotions, which in turn helped Michael control them, as they never got too far out of hand, helping him gain control over them, even with his hormonal infant body.
Michael was three years old when preschool started for the first time, while he was reluctant to interact with three year old kids, he knew social relations were important, he was isolated as a child in his previous life, which led him to becoming lonely because he didn't know how to really make friends, he had a lot of acquaintances he would greet, but none of them could be considered friends, Michael believed this was because of the stunted growth of his social skills, something he would try to remedy this life, he wanted to become an icon, similar to all might, this meant he would have to interact with hundreds, if not thousands of people on a daily basis, including reporters.
As he was walked in to the class by the teacher he noticed that many of the kids seemed even more scared and nervous than he was, especially a kid with black and green hair who seemed to be very close to a blonde haired child, who seemed the complete opposite, holding himself with extreme confidence, borderline arrogance.
Michael recognized them as probably being two of the main character of the manga and anime, Izuku Midoriya and Katsuki Bakugo respectively. He decided they were probably be worth approaching, since they were able get into U.A in the anime.
"Hello, My name's Michael Steele"
"My names Katsuki Bakugo, you better remember it when I become the number 1 hero!"
"Sorry about Kachhan, my names Izuku Midoriya"
"So, you guys wanna be friends?"
"Yeah sure you can be my minion."
"Not interested in being a minion, isn't that something villains do? I'm going to try to become the greatest hero too!"
"So am I! Me, you and Kachhan can be the three greatest heroes in the world!"
"So you're a rival huh, i'll make everyone eat my dust while I become number one, though you guys can be number two and three."
"Wanna watch all might videos? I'm sure I can convince the teacher to let us watch some on her computer" says Michael
"Yeah All Might's the best! I wanna be a hero like him when I grow up!"
"Hell yeah, All Mights awesome, although i'll take his place as number one when I grow up."
"Katsuki! Language!" says the teacher
"Sure, sure, god shes just like my mother, just less loud."
"Shes probably just looking out for you, i'll go convince the teacher."
The three ended up getting closer throughout the first year of preschool, right up until Katsuki reached the age of four, being two months older than Michael and nearly four months older than Izuku, and manifested his quirk, "Explosion" which allows him to secrete a nitroglycerin-like sweat from his palms and allows him to detonate the sweat at will causing explosions, these explosions became more powerful the more Katuski sweats.
He manifested his quirk at preschool and was praised constantly for it, this has started an "I am the best" mentality which fed his ego massively even as a child making him more arrogant and confident than he previously was, he stopped hanging out with Izuku and Michael, outright ignoring them occasionally to hang out with his crowd of minions, constantly praising him and making him he was the best. Something Michael refused to do, while Izuku treating Katsuki as an equal and calling him Kachhan instead of treating him like hes better than them caused Katsuki to pull away from them.
This was up until the day Michael manifested his quirk, nearly four months after Katsuki did, during class, he started gaining a golden glow, his piercing blue eyes seemed to see right through you. He then seemed to move much quicker than what should be possible for an nine year old, much less a four year old. He carried tables like they were paper. The teacher was shocked at another powerful quirk user being in her class, and quickly called in Michael's parents. While this was happening the kids were staring at Michael in shock and awe. The golden glow made him seem almost angelic, like a hero, while the strength and speed he showcased made them realize he could be the next all might if he kept getting stronger.
Katsuki was in shock but chose to believe that his own quirk was better than Michael's, what was super speed and strength in front of a massive explosion. While Izuku was in awe of his quirk, but also slightly afraid of Michael ignoring him like Bakugo did, as the kids started crowding around him, Michael walked straight back to Izuku, and started talking to him about his quirk, ignoring the crowd of kids still in awe of his quirk. Calming Izuku down and making him realize Michael wasn't like Katsuki. He had always treated him like an equal while Katsuki always treated him like a minion, someone to boss around.
Michael's parents then showed up in class, where Michael showed them his quirk, which shocked them as it wasn't heat vision, they then asked him to try to use his quirk on his eyes while looking outside the window, where suddenly a ray of red light shot out of his eyes. His parents thought then, that the heat vision was just an application of his quirk, not his quirk itself, which made them even more amazed and proud of their son, a general enhancement quirk as well as heat vision. That was an incredible combo that is definitely a top 10 pro level quirk, as long as he trains and uses it correctly. While the students were even more amazed at his eye lasers, with Izuku mumbling on about its application and Katsuki thinking 'My Quirk's still better than his, right? Yeah definitely, nothing can stand in front of a massive explosion!'
