Who are we to decide the monsters? (BNHA male reader insert)

Chapter: 1, A monster descends.

'Fuck... where am I?' I thought as I tried to recollect my memories, although a strenuous process I managed to find out who I am, I am Alexander Michaelson, I was a 5-star army general in the third world war, who was assassinated by my Lieutenant, 'I should've known that slimy bastard would betray me!' I thought furiously, but I was brought out of my brooding by the giant light that had appeared out of nowhere. "Calm yourself, child." the light said in a calm fatherly voice.

"Who are you? And what do you want?" I asked calmly, this was not the first time something strange happened but I don't want to take any chances, "I am the Lord of creation, and you have died, I am here to give you a second chance because every action you took, no matter how drastic, no matter how cruel, you did it with the intention to protect, and for that, I will grant you, Reincarnation in a world of your choosing and three wishes." He explained in that still calm voice.

"Alright then, I guess if there's nothing else I can do, fine." I accepted easily. "I want to be reincarnated in the 'my hero academia' world on the day it starts, I wish for the powers of Glitchtale Gaster, and  Seraphim Sans, second I wish for Yujiro Hanmas strength, and third I wish for all the martial prowess from the Baki and Kengen Asura manga," I stated calmly, I had been quite the nerd back in 2026.

"Done, done, and done. Farewell my child, may your second life be great." And with that, I passed out.

I then woke up to the voice of what seemed like a middle-aged man I looked up and saw I was in a classroom wearing an extremely large uniform "L/N! Mister L/N just because it's the last day of school, doesn't mean you can slack off!" He yelled, in response, I just itched my ear. "So as third-year students it's time to start thinking seriously about your futures and what you're going to do with your lives. I could pass out some career aptitude test, but, why to bother I know you all want to go to the hero track" he finished as he threw the Aptitude tests in the air and everyone started using their quirks except me and Bakugo, wait, can Aizawa nullify my quirk, I'll find out later. "Yes, yes you've got some very impressive quirks, but no power usage allowed in school!"

At this point I just started ignoring everything, I looked down and saw a black wallet on my desk and it had my name etched on it, I opened the wallet to see a note from God that said I had infinite money, a car, and a motorcycle, Matte black Harley Davidson. When I looked up everyone was walking out of class, I started packing up until I heard Bakugo's voice. He was talking about Izuku's Hero analysis, "Fuck off Bakugo," I yelled, he turned to me and became furious and started stomping towards me but before he could do anything I used the palm of the void and knocked him out with a single touch. "Take him to the nurse. He'll wake up in 3 hours."The two idiots looked at me and ran carrying Bakugo. "T-Thank you L/N-san!" 

"It's fine, call me Y/N," I said walking towards the door.

"U-um Y/N, if-if you mind me asking, was that your Q-Quirk?" He asked timidly,

"Nah, it's just martial arts technique. I'll see you round Midoria," I explained in reply

"Izuku! Call me Izuku!"

"Later Izuku."

I then started walking around town looking at shops and purchasing things here and there, but what got my attention was a loud explosion, It 'started' I thought as I began to run as fast as I could, eventually my leg muscles were the size of Yujiros. When I got there I saw Izuku running in as well as hearing the shitstain heroes doing jack-shit. I immediately ran extremely fast and summoned two large hands to grab hold of Bakugo and Izuku. As I summoned a blaster to obliterate the piss-stain, All-Might ran in to punch the villain, so I made the blaster shield the civilians, and once all of that was done I de-summoned the constructs and grabbed a Cigar from a pack that I bought earlier.
