preds' physical appearances can vary in many different ways. If u look at the original pred compared to the second one for instance, their markings were completely different, & not only their skin tones, but the composition of their facial structure & their skin itself seemed to be quite different, with the second pred having much more rough & hard looking features, somewhat like a crab or a lobster. Also, many of the preds at the end of pred 2 had very distinct features, one of them had large bony structures surrounding it's crown, with strong patterns running across it's head, wheras another had a smaller, more crunched-in face, with less defined markings & a different skin tone, if u actually take a good look at each individual pred u see, u will notice worlds of difference
