Check out this series of incredibly menacing looking villain character designs for He-Man's Masters of the Universe from artist Nathan Rosario. I grew up on He-Man and the Masters of the Universe, it was a great cartoon with a badass toyline, which I had a ton of. So it's always cool coming across fun fan-made art like this. Hopefully that live action movie that's been trying to get made for the last few years will actually happen sometime soon. Check out the series of art below, and tell us what you think!
