The Thousand Suns (pre Heresy) and those metallic monsters with scythes for arms that can slice a space marine in two in seconds (forgot their name, but they are in one of the first books I read.) Also love the Grey Knights and obviously Horus was a great enemy (until he had a massive stupid attack and let the Emperor on board his ship!)
