The body itself is more or less okay, having a bulky, muscular build. Except for those dreadlocks. And maybe a facial structure could be a bit different.
Do we even WANT super mutants in FO4? One or two maybe but I do not see the need to put them in the game as far as canon goes. I find them to be much more enjoyable and memorable when they are few and far between. Maybe even a body of one? It has been a long time since FO1, they should be pretty rare in my opinion.
I agree with basically everyone. We really don't need any more super mutants, and if we do get some, hopefully they won't change much from wha tthey are already.
