After carefully looking at the trailers on KP2, I realized that all 3 variations have different masks and I've compiled an image below to prove it.

The 1st image is the first variation, he sports a regular ripped off human face skin. He wears a short sleeved, checkered pattern shirt (green / gray) with the bloody apron on.

2nd image has him wearing a mask that's kinda darker, looks like it has stitches on some parts of it. He wears a red shirt, with a long sleeve sweater or shirt underneath (you can see his forearms are covered). This variation most likely incorporates the hammer into his style. Still wears the bloody apron on this one.

3rd image has a different mask, his "dinner" mask with the makeup on. He wears a suit which looks completely different than what he wears for his other 2 mentioned above.

So I thought this was interesting, kinda like how Triborg has different colors and helmets for each variation, Leatherface technically has 3 costumes if you think about it. Makes me hate him a little less lol. I'm kidding, I'm over it, still upset but it is what it is. I'll definitely try him out.
