Two new Dragon-Type evo chains have been introduced: Deino-Zweilous-Hydreigon and Axew-Fraxure-Haxorus. There is also a stand-alone Dragon known as Druddigon. Axew, Fraxure, Haxorus and Druddigon are ALL pure Dragon types, while Deino and its evos are Dark/Dragon. Dragon is the final gym in Unova, and it has TWO gym leaders which change depending on which version you're using. If you liked Salamence and couldn't live without Garchomp, then you're gonna love this generation.
