Aerodactyl is a dual type Rock- and Flying-type Pokémon. It is resistant against Bug-, Fire-, Flying-, Ground-, Normal-, and Poison-type attacks. To defeat Aerodactyl, players should focus on using Water-, Electric-, and Rock-type moves. Here are some of the best counters against Aerodactyl:

• Primal Kyogre
• Shadow Metagross
• Mega Swampert
• Mega Diancie
• Mega Blastoise
• Shadow Raikou
• Xurkitree
• Metagross
• Zekrom
• Rampardos
• Rhyperior
• Kyogre
• Swampert

It is important to note that Aerodactyl has three different fast moves, and the key to defeating it is using Pokémon with a double resistance to its fast move, rather than dealing super effective damage. For example, Magnezone with Spark + Mirror Shot is a good choice because it has a double resistance against Steel-type moves such as Steel Wing, and Mirror Shot has a 30% chance to lower Aerodactyls Attack. Scrafty with Bite is also a good counter.
