As Michael got older, his powers, control over his quirk, and his size all increased. As a 12 year old entering puberty, Michael is 157 cm tall, as well as having muscles gained from training nearly all of his life. With his pitch black hair, and his piercing shade of blue eyes, he could be considered to have a ten out of ten appearance, coupled with his intelligence, scoring full marks on every test possible, as well as a genius level IQ of 208, far smarter than all but the greatest of quirk enhanced minds. He was also the champion of every martial arts tournament he participated in, whether local or national. He's considered a genius in every way, earning him a lot of fans, especially girls. The males respected him for his intelligence, strength and humble, kind personality. While the girls were attracted by his appearance and natural aura of kindness.

Throughout all of this, Izuku still remained as Michael's closest friend, while Bakugo, who saw Michael earn all of this attention and praise, started treating him as a rival, the one to beat, while completely ignoring Izuku whenever possible, while putting him down or just attempting to use his quirk on Izuku to get him out of the way, which Michael blocks before neutralizing Bakugo, leaving him no way to fight back through his use of martial arts, mainly Aikido. This causes Bakugo's anger to turn into fury each time. Yet he is unable to do anything, and is forced to walk away after being let go by Michael.

Michael, at this age, unlocked many more of his kryptonian powers, he was much, much faster and stronger than before. His invulnerability is enough to be almost completely unaffected by Bakugo's strongest explosions, as well as bullets and blunt weapons. He developed X-Ray vision, as well as super breath, to which he can blow gusts of winds able to push people as well as smaller cars into the distance, with him being able to control how cold it is, from feeling only strong winds, to freezing temperatures. He could also leap much further, able to jump across small buildings. His heat vision could now melt concrete, tested out on the street near his house, yet he could not use it on people, that would melt them

He also developed super senses, they seemed to grow massively, to the point where he could hear everything within a few kilometers, when he first developed his super sense, he could not handle the information or filter out any of the voices. He could also see much further, with a higher resolution than the average human being looking at his palm, while looking at a car 200 meters away.

These super senses caused more harm than good until Michael mentioned his troubles to his parents, who took him to a quirk therapist, someone specially trained to deal with quirks that either harmed or had the potential to harm the user, or which came with physiological consequences, who helped him understand his super senses better, allowing him to filter out the majority of the sounds he could hear, as well as get used to to seeing so far, and in such detail.

His skill and strength in martial arts, allows him to beat martial art masters around 30-40 years old, in pure skill. With his strength, he was very hard to defeat, often training with Haruto, who could rely on his six arms to counter most of Michael's moves, redirecting his strength and is able to beat Michael regularly. Michael, without holding back his quirk, which he could control enough to give himself a general enhancement, almost doubling his strength and speed, while recovering his own stamina and healing slowly from his injuries. Not enough healing to make much of a difference in a fight, but enough to increase his recovery speed from injuries and heal any residual injuries from training.

Michael Steele, to the public, was considered a prodigy of martial arts, with an incredible quirk, while also being a genius, as well as handsome. This caused him to have a some public fame, even as a 12 year old, he was considered a shoe-in for UA, and was even approached by some pro-heroes, offering him positions as their sidekick after he graduates from a hero school, as well as some of them offering to give him a recommendation to U.A. Which he refused, saying he hadn't earned it as the heroes didn't know him enough personally, which he believes to be unfair to other applicants to hero schools like U.A. He would go the normal way, through the exam. This earned him the respect of many other heroes, as well as civilians and other aspiring heroes.

Michael Steele, along with his family would be visiting his aunt from his mothers side, to meet his now three year old cousin Kota, Kota's parents were always too busy for Michael's family to visit, with their job as a pro hero duo. They would never be able to properly greet them, they did however have enough time for Michael's family to visit and live with them for a few days, as their home was quite far away. Michael was meeting his aunt and her husband for the third time in his life now, they had visited them in Mustafu, Japan twice before his cousin Kota was born, so it would be his first time meeting Kota.

His aunt, Akane Izumi, was a pleasant, fun person to be around, playful most of the time but serious when it came to doing her job as a pro hero, her quirk was the ability to manipulate water, while being able to create little of it, she is however able to control water from other sources, and has enough control to be able to siphon a tiny amount of water from the air, not enough to matter in a fight but enough to amaze kids and civilians. Her husband, Sora Izumi, was just as much of a pleasant person, he was a little more mischievous than his wife, but was even more serious with his job as a pro hero. His Quirk allows him to create a large amount of water, and shoot them out of his hands, he is however unable to control the water further than that. They had met in a hero school in Tokyo, from there they become a hero duo, eventually fell in love and with the great combination of their quirk, became a well known A-rank hero duo.

They treated Michael very kindly and always did their best to help him whenever they could, whether helping out with tips for using his quirk, or offering to give him a recommendation to a hero school, which he refused because he wanted to prove himself, not just to himself, but to the public and U.A as well. He would first get first place in the entrance exam, then dominate the sports festival. He may be doing it partly for fame, but he wanted the world to know he was here, he wanted to create a legend that made the majority of potential villains so scared they wouldn't dare commit a crime, while giving hope to the public, similar to All-Might, but he wouldn't let them rely on him completely, which was the biggest mistake All-Might made, he would advocate kindness and helping others in need, no matter who they are. This was just the most efficient way to achieve his goal.
