Aerodactyl

The combination of Aerodactyl's great Attack and Speed makes it a versatile offensive threat. It can function as a formidable wallbreaker, Pursuit trapper, and revenge killer capable of threatening other frail fast attackers such as Sceptile, Heliolisk, Delphox, and Sigilyph while threatening bulky Pokemon such as Blastoise and defensive Slowking with 2HKOs after Stealth Rock. While Aerodactyl is rather threatening offensively, its typing also provides it with benefits defensively, most notably letting it switch into and check Pokemon such as Incineroar, Braviary, and Vivillon and recover health with Roost. Unfortunately, Aerodactyl struggles to reliably break through common defensive Pokemon such as Steelix and Rhydon due to their resistance to Stone Edge and ability to take even Choice Band-boosted Earthquake with their great physical bulk. Additionally, Aerodactyl's Stealth Rock weakness combined with its poor bulk limits its ability to switch into resisted hits from the likes of Magmortar and Vivillon. Similarly, Z-Move variants of Aerodactyl will be forced to spend turns using Roost so they remain healthy enough to check Pokemon such as Incineroar, causing them to give up momentum. Furthermore, Aerodactyl's poor bulk leaves it susceptible to revenge killing from Pokemon such as Choice Scarf Passimian and Togedemaru as well as Sneasel.
