Beedrill

Beedrill shines in the UU metagame thanks to its Mega Evolution, which, by way of amazing Attack and Speed stats and Adaptability, grants it the strongest U-turn in the tier, letting it pummel offensive and defensive teams alike. It can grab offensive momentum with very little trouble thanks to the aforementioned qualities, which makes it one of the best offensive Pokemon in the tier. However, Beedrill has a somewhat shallow movepool aside from its STAB attacks, and it only has access to Knock Off and Drill Run as offensive coverage moves. It also has pitiful defensive stats, as well as a mediocre defensive typing. It also is forced to run Protect so that it can Mega Evolve and get the Speed boost without taking damage, as its Speed before Mega Evolving is decent at best. Despite these flaws, Beedrill is still a fantastic Pokemon, and it should always be considered when making an offensive team.
