I can't believe Ranma 1/2, Macross (any version), Robotech, Gundam (Mobile Suit Gundam; Gundam Wing), Ren & Stimpy, Voltron (the lions especially), Battle of the Planets (or its parent program), Rocky and Bullwinkle, Mr. Magoo, Transformers, The Beatles, The Jackson 5, The Monkees, Speed Racer, School House Rock, Dungeons and Dragons, and Dirty Pair were all below the cut.

Including animated features, which some would call cartoons, in addition to animated series, I have to also mention Titan AE, Tank Police, Perfect Blue, Vampire Hunter D, Ghost in the Shell, 8 Man, Heavy Metal (the original), The Black Cauldron, Princess Mononoke, Milan, and Prince of Egypt among the list of all-time greats.
