Purugly

Despite its fat and clumsy appearance, Purugly is a fast Pokemon that is capable of scouting and revenge killing. U-turn and higher Speed sets it apart from Kangaskhan, while it is speedier and slightly bulkier than Liepard. Thick Fat also helps it to switch into certain moves such as Hidden Power Ice from Rotom-F. However, its poor movepool leaves it walled by Rock- and Steel-types, and while it is able to distinguish itself from its competition, most of the time, they aren't enough to justify its use over Kangaskhan, which has Scrappy, and Liepard, which has Prankster Encore and Pursuit. They are also both more powerful than Purugly and have better neutral coverage.
