Druddigon

UU is a lot less ferocious than OU, and this is largely due to the fact that most of the Dragon-types reside in the upper tiers. As a result, Druddigon has a niche as a bulky Dragon-type in UU, possessing more overall bulk than Flygon and more power than Kingdra, the other two main Dragon-types used in the tier. Druddigon also gets access to Glare, making it a more than viable addition to a team looking for a reliable paralysis inducer. It does have its problems though, as its lack of reliable recovery coupled with only average defensive stats mean that Druddigon can get worn down and defeated fairly quickly. Another problem is that while it does have a great Attack stat, it doesn't have the Speed or movepool necessary in order to sweep properly. That being said, Druddigon's bulk, unique mono-Dragon typing, high Attack stat, and access to support moves such as Stealth Rock and Glare make it a worthy replacement over Flygon or Kingdra for many teams.
