Dragonite

While Dragonite's presence in OU has often been harmed by faster, sleeker Dragon-types such Salamence, Dream World brought it one of the most game changing abilities: Multiscale. With Multiscale, Dragonite gained the ability to set up on nearly every threat in the metagame due to Multiscale halving damage from attacks when at full health. Additionally, Dragonite's large movepool and great offensive stats make it one of the scariest sweepers in the metagame. While Dragonite's Speed may seem underwhelming, its bulk and versatility compensates, and it is thus one of the most fearsome Pokemon in the Dream World metagame.
