Something that could help a lot and I wouldn't do it immediately is the Hercules method. It could help him train everything, because that's what it's all about: the balance of mind, body, and soul, if I'm not mistaken.

It has nothing to do with it, but Ryu is the best. For a love interest, why not a girl from another anime? It will make it more interesting. It has to be someone badass, for example: Maki, Esdeath.

If it's Kaido he has to be op since he gets it, we're talking about a guy who as a child they already tried to execute him and they couldn't, not much is known about Rocks, it gives play to the imagination, Redfield has an observation haki capable of reading minds if I remember correctly, Ace is the most normal, but only because he didn't show himself enough, for me he has more potential than Luffy, without the fruit obviously, as for Roger and Luffy they have the voice of all things, in theory that could help with senjutsu, an advantage that Luffy has is that he learns and grows by fighting, this is just my opinion maybe it can help you choose

Epic, I should erase his memories, someone motivated by hate like Levy could find a way back

The AI ​​is strong in this story, repetitive chapters, no real content, what a disappointment, the character is boring, doesn't think, experiment or try to innovate

Is he just Kryptonian or is he a Viltrumite with Kryptonian abilities? Because intelligent atoms are too op not to have them.

I really like this story, one of the few invincible ones. Honestly, I don't want Amber to be a couple. It's boring both in the series and in the comics, it would be just filler. You have Eve, M Girl, and Anissa, that's totally unnecessary. Also, if she starts traveling to other universes like Marvel, it will probably expand.

I like your story, but it's too redundant, things you already said or explained, you repeat it over and over again, you probably used ia, I'm not saying it's wrong but review it, because it becomes tedious and boring to read, on the other hand the synopsis says he reincarnates as Izuku, I don't know what will happen in the following chapters but if not, change it

The story is very interesting, I like Makima as queen, she is an interesting character, how she will adapt to the new abilities and possibilities with her powers, I hope to see it, personally I never liked Asia, it always seemed to me that she avoided the relationship between Issei and Rias, she was insufferable and very pathetic, she never seemed to really improve, I hope that changes, that she grows, she could be incredible, a healer like Tsunade, her sacred gear could have a subspecies that heals her, it would be very badass

His name is really bad, Sung Jin, really? At least call him just Jin, what's the need to use Jin Woo's name?
