Harry doesn't want to be a wizard, he wants to be a superhero

Harry's Diary:
On June 1991, 6, I traveled to another world and was adopted by a couple. They were very gentle and much better than my aunt's family!
On July 1991, 7, I returned to my original world and received a mysterious email. Oh my God, it was a magic school!
On August 1991, 8, I saved the world's richest man, Tony Stark!
On 1991/9/9, I encountered a mysterious man. He seemed... very weak?
1991/10/10 I was accepted as a disciple by the Supreme Mage. Relying on the magic power in my body, I don’t need to pay the price like others!
1991/11/11 I became the greatest wizard ever!
……
Many years later, Harry Potter, the Sorcerer Supreme, the Master of Chaos, the Third Dark Lord, the most powerful wizard in history, faced the frantic reporters and said calmly:
"Though Thanos is very weak, he is right about one thing: this world needs a new order!"
