He have heroic
Edit: pic removed to protect identity. I suggest you submit a ticket to support via the in game system if you suspect he is a hacker. However I see nothing in that pic to indicate he is a hacker, each of those heroics released years ago with opportunities to get orbs or more so what makes you think that he is a hacker? FYI he could legitimately be in the same arena as you even though they are not allowed because of the last team he used and he has not been active since the changeover to prevent his heroics from showing up as opponents for you. Please do some research before jumping to the conclusion that he is a hacker.
