Hydreigon is a Dark & Dragon type Pseudo-Legendary of Unova, is the fully evolved form of Deino, and is another pokemon that I find has an amazing design. Hydreigon is fairly good both in games & competitively too, as Hydreigon has solid stats, a solid movepool & pretty good abilities. You can basically use Hydreigon both as a Physical or Special attacker, and it'll do good, just have to be wary of fairies. Anyways, this was a tough decision deciding who to rank here honestly, but it came down to what appealed less from the 7, and it was Hydreigon.
