Durant

Despite its small size, Durant is a major powerhouse. A base 109 Attack stat coupled with Hustle gives Durant a stat over 500 right away with an Attack boosting nature, which leaves many Pokemon walking cautiously when it enters the field. Durant is also blessed with Hone Claws, which helps it patch up the loss of accuracy Hustle causes; Hone Claws also raises Durant's Attack stat in the process, giving it an Attack of over 700 after just one boost. Not only does Durant hit hard, but it also hits fast. A blazing fast base 109 Speed stat leaves base 105 Speed Pokemon, as well as Cobalion and Galvantula, in the dust as Durant plows through the opposition. Durant is also blessed with a good typing. Defensively, its Steel typing gives Durant good resistances, especially useful when coupled with a base 112 Defense stat, while offensively, its Bug typing gives it a great STAB; the two combined gives Durant only one crippling weakness to Fire-type moves. However, it's not all roses for this little ant. Durant has utterly awful special stats, meaning it can't even take a resisted special move well at all, while using a special move is out of the question. Durant's shallow physical movepool is a letdown as well, as it's left with only four viable moves: X-Scissor, Iron Head, Superpower, and Rock Slide. However, due to its fantastic offensive stats, Hustle, Hone Claws, and good typing, Durant makes for a very dangerous offensive threat which you should always be prepared to deal with.
