Aerodactyl is a Rock and Flying-type Pokémon, which means it is weak against Water, Electric, and Rock-type moves. Some of the best counters for Aerodactyl include Primal Kyogre, Shadow Metagross, Mega Swampert, Mega Diancie, Mega Blastoise, Shadow Raikou, Blastoise (Mega), Xurkitree, Zekrom, Rampardos, Kyogre, and Rhyperior. Additionally, Mamoswine with Powder Snow and Avalanche can be used to quickly and effectively faint Aerodactyl. It is important to note that when battling against Cliff in Pokémon Go, Aerodactyl will be the first Pokémon you’ll face, so it is recommended to bring Pokémon that know Water, Ice, Rock, Steel, or Electric-type moves.
