Well in that case then Karg is the stand in for Trap Jaw .
I too think that Beastman looked much like Grizzlor thats a good thing. Ol Grizzly is a far more realistic beastman clone . Imagine trying to translate bright orange fur , exotic armour and a wolf/ape face into live action .
Personally i feel they could have done a better job for the characters . The toys are just over muscled human torso,s with a strange monster faces . Beastman might be an exception but they could have made Tri Klops , Trap Jaw and Kobra Khan rather easy . Even Orko should have been nothing . Orko is a very basic design and no mouth to worry about . Ten years before we had a believable yet more complex on screen puppet called Yoda .
