Aerodactyl

Mega Aerodactyl is one of the most dominant offensive Pokemon in the UU metagame thanks to its combination of speed, power, and versatility, allowing it to fit on every team archetype. Its immense base 150 Speed makes it the fastest unboosted Pokemon in the tier. A sizable base 135 Attack coupled with Tough Claws and a wide arsenal of moves, such as Stone Edge, Earthquake, Ice Fang, and Pursuit, allows Mega Aerodactyl to hit a vast amount of Pokemon in the tier super effectively. Pursuit lets it trap common Pokemon, such as Latias, Gengar, and Celebi. However, even with its vast movepool, Mega Aerodactyl still does not possess the necessary firepower to break through some of UU's bulkier walls, such as Swampert and Mega Aggron. Mega Aerodactyl is also susceptible to Stealth Rock due to its part Flying typing and weak to the powerful priority moves that flood the UU metagame, such as Bullet Punch from Scizor and Ice Shard from Mamoswine, meaning that it can be worn down rather easily when not packing Roost. Lastly, Mega Aerodactyl is outsped by common Choice Scarf users such as Krookodile and Hydreigon, which can revenge kill it after Stealth Rock damage.
