It's the way you word it.. anyway..
You're missing my point here. None of the ATs are actually detailed (how do I explain this.. textured properly, modeled with enough polys..etc.), and as they should they're all low poly models. Issac model had some details.. or let's call it extra polys that I didn't see from other fighters, yet he had none of the textures served for the likes of Springman for example. He's missing some gradients too. I think a 3D modler will word it better that I do.
Black Knight is an apparent low poly.
That's why I said it might've been a very early cut.
This is what I could find for now:
