Chris Aftons my hero academia problem

The shadows and nightmares accidentally sent Chris to a different universe.to be more specific,the universe of my hero academia. The others have no way of getting him back,but they can communicate and help him to adapt and learn about his new home.after a few years,Chris is doing amazing(mostly due to the fact that the shadows and nightmares kept transporting things like money to him)but what will happen when a certain pro-hero hears and sees him talking to nightmare?
