Another example? Obadiah Stane is never referred to as "Iron Monger", or Ivan Vanko as "Whiplash" in the movie, but there were enough official anouncements of their identity as such back in the day

So, as Drax and Ronan have been referred as such, they must stay. Korath, on the other hand, can be debatable.
