I Would vote for a tech anime next like any Gundam series. he has already gotten a lot of power from hunter x hunter I believe it would be a good change of pace to have him get tech next. I would recommend iron blood orphan gundam series it had a lot of potential for tech (Ahab reactors, mind Machin nanotech, healing nanotech, and so on.) and who would not want to get a giant robot.
