The tcg has Zombie Dragons as well, on cards like Necrodragon Galbazeek, so they aren't just tcg/ocg exclusive.
I'm pretty sure those are just mistranslations. It happens all the time. Zombie Dragons and Dragon Zombies are the same thing. You can tell because Necrodragon Giland, a Zombie Dragon in English, is a Dragon Zombie in Japanese. For the sake of consistency, let's just keep Zombie Dragon to follow the pattern of Earth Dragon, Volcano Dragon, 'xxx-Dragon' etc. and delete Dragon Zombie.

Actually, no reason to delete, just can have notes on the trivia pages for the few Zombie Dragons noting the difference in English, and that's it. There's only the few cards like the few I mentioned earlier. If I haven't already put something in, it can be noted on both of the race pages as well. Yami_Michael 04:22, August 3, 2010 (UTC)
