I hope you guys like it. So, Y/N will be either an antagonist, protagonist, or anti-hero in each arc/chapter. It depends how much good or evil he is. 

Maybe for the rest of the story Y/N might regret what he has done, but he is not going to stop to get rid of system. He might become like a Red Hood character. 

But not like Red Hood just an anti hero kind, he won't go to UA unless he has his reasons for doing so. I'll also have Arc, Wanda, Hitomi, Robbie, and Shuri along with some UA students join both the Avengers and Spider-Man's team in marvel episodes. 

Anyway, since I'm adding marvel into the book I'm opened to having any marvel harem members.  

Let me know what you guys think at the comments below, peace out and enjoy!
