>>32301893I imagine the question being asked is "why". Why is a dog allowed to have Dragon-type, while a Dragon isn't. I get it that Dragons were a special thing back in Generation I, but they aren't anymore. Why has the type remained? Flying-type hurts Charizard more than it helps, I have yet to meet a Zardfag who liked the Flying-type, so why keep it, other than being stubborn?
If that is indeed the question you're asking, the answer is, because they can. They're almost afraid of messing with the series' popular Pokemon. They went out of their way to make an extra Mega, simply because they didn't want to remove the Flying-type and potentially upset fans.
