Just believe it. This one right here is what you would call a proper ff, out of 99% of the garbage in this website.
How about making the abilities that are capable by humans integrate into his self. Like catwoman is human so her reflexes are like the epitome of what humans could achieve and if he uses her abilities more and more, his body starts etching that ability permanently in him. Same with lex's intellect.
So far I love your thought process. Feels like we have similar tastes. I honestly don't like : 1. OP Mc's from the start. 2. I honestly like system novels, but only the ones that show stats or the like. I don't like levelling systems. And I especially don't like systems that give powers from different worlds altogether. 3. I love single FMs and abhor stupidly put-up harems. Reasonable harems are decent. 4. And I also love character and Intellect development.
Zenin Maki plssssssssss
Just a thought, make him have spider spider fruit. Sounds inconsequential but in its hybrid state you can make him have spider legs coming out of his back like iron-spider. You can also have him shoot webs through the spider legs, fingers(like Jess) and surely wrists. Since he also has good reflexes and observation haki he would almost fight like spider man. It's just an idea. No need to implement it.
Bro it's oroboros
No Harem
NP bro just was saying that it would make him too OP
Just my thought and a suggestion. I think you should remove creeping hunger from the story. I know that sounds wrong as the story's name is creeping hunger. But the object seems kinda useless in the marvel world where there are a lot of ways to gain different abilities.
ic, thanx
