Orc is a race of mythical brutish, repolsive orge-like creatures.
J. R. R. TolkienEdit
J. R. R. Tolkien got the idea of orcs, where they contrast with the benevolent Elv ish race.
What's that you say? Orc's skin color can be different? I never heard of it either. There skin goes to black to grey to green, and sometimes, very rarely, red. Wow!
