Some are more popular than others, but probably due to them creating Tom & Jerry, pretty much any Hanna-Barbera cartoon from the '60s and '70s were dubbed and given their own Japanese intros and names. Scooby Doo, for instance, was 'Wimpy Krooper', the Fantastic Four was 'Space Ninja Golmes' (Gum+Holmes) with his companions Suzy, Fireboy and Gunrock, and even more obscure fair like Groovy Ghoulies, Funky Phantom, and The Impossibles got the full treatment.
Plus, Transformers, South Park, Spongebob, PPG, TMNT, Teen Titans, Teenage Robot, X-Men, and probably a few more I can't remember.
