The super part did not make it into the film, at all, just this "the bigger ones hunt the smaller ones some sort of blood feud" from the oh so reliable narrator survivor Nolan.
Sure they are taller but it takes three to do what one does in the prior two films, beating an emaciated prisoner and taking as long as it even does with the Berserker leader versus a Jungle Hunter, does not do their image any favours in that respect either.
