Yeah, that was a fan-made name because we didn't know its actual name. Then there was Togepi before it. In fact, if you want to see which pokemon was introduced first from each generation (Except the first generation) look at the banner at the top of these forums. Togepi, Kecleon, and Munchlax were all introduced via the anime. Zoroark was shown on a TV show and Chespin was unveiled along with the other starters online.
