Sculpture Identification?

[Kao]

Hey there! Below I have 3 sculptures which I'm trying to identify. The first looks something like a Samurai to me, while the last two look Roman or Greek. I haven't been able to identify them myself, so I was hoping you kind people could help. Any ideas?

(p.s. Sorry about the poor image quality. It can't be helped, sadly)

The first one is not a Samurai. Perhaps you can give us a hint
about the source, since the image quality is so distorted and
lacks any details.

Sure.

Lesse, I snagged these files from a video game. But upon inspecting these closely, they seemed to have much more detail than any sprite artist would be willing to put into a drawing, so I figured they must have been real sculptures at one point.

I really don't have much more information than that. I'm sorry. Any help is really appreciated, though!
