Crobat

Crobat's unique combination of stats, typing, and movepool make it an interesting Pokemon in UU. By virtue of its decent bulk, Speed, and Attack, Crobat is arguably the best check to Fighting- and Grass-type Pokemon in UU, having enough bulk and a good typing to take any of their STAB moves and the Speed and Attack to strike back. It has a great movepool, including access to Defog, Taunt, U-turn, Roost, and STAB moves of choice, allowing it to function as an excellent team supporter. Thanks to its amazing Speed and decent Attack stats, it can be an effective user of Choice Band for decimating offensive teams. While decent enough to get by, base 90 Attack is nothing to write home about, so Crobat's Choice Band set often isn't powerful enough to take apart defensive builds. The same goes for Crobat's bulk; while it gets the job done, don't expect Crobat to be sponging attacks all day long.
