Zweilous

Hustle is Zweilous's most significant trait, giving a massive power boost to its physical attacks. This is augmented by Zweilous's access to powerful STAB moves and decent neutral coverage, making it very tricky to withstand Zweilous's attacks. Zweilous also has some useful resistances to Fire, Grass, and Dark, as well as a Psychic immunity, which allows it to check Pokemon such as Zebstrika and Leafeon. That said, its typing also comes with very inconvenient weaknesses, most notably to Fighting and Ice, which isn't helped by its low Speed. Hustle also lowers the accuracy of Zweilous's physical moves, meaning that despite its power, Zweilous can easily whiff and accomplish nothing. Zweilous also competes with Fraxure as a hard-hitting physical Dragon, as Fraxure has better accuracy and the ability to boost its stats.
