I need to get the "Point Counter-Point" achievement which requires me to do the Deathstroke battle without missing a single counter. I have already beaten the game and the New Game Plus mode, though, and I am at the Deathstroke battle in the I am the Night mode.
Without the counter icons it is nearly impossible to do this battle in I am the Night mode (plus, I won't know if I even missed a counter and didn't realize it). If I don't get the achievement when I do the battle in this mode, how do I go back and replay the Deathstroke battle to get the achievement?

There is no active way to replay boss fights in Batman: Arkham Origins. Confirmed on Steam, and on GameFAQs, here and here.
It is even confirmed on TrueAchievements as a missable achievement, meaning that if you do not unlock the achievement when it is open to you, there is no going back to retry.
