Aerodactyl

Mega Aerodactyl is an excellent fit on offensive teams due to its blazing Speed stat that works well with its access to Stealth Rock and Taunt. These attributes allow Mega Aerodactyl to set up Stealth Rock and prevent Defog users from removing it so long as Mega Aerodactyl is out, which makes it a good fit on Spikes-stacking teams. Because Mega Aerodactyl gets excellent coverage with Stone Edge and Earthquake, it can easily afford to run both Stealth Rock and Taunt. Aerodactyl also possesses the ability to revenge kill fast offensive threats, such as Mewtwo and Darkrai, while checking Ho-Oh and Mega Salamence. Unfortunately, Mega Aerodactyl is relatively weak by Ubers standards and will have a difficult time 2HKOing the majority of the metagame. It is also not bulky enough to survive more than one strong neutral hit from Pokemon such as Xerneas and Mega Gengar. Because of its frailty and its Stealth Rock weakness, there is a good chance that Aerodactyl will not last more than one turn if it is conserved for the mid-game. Mega Aerodactyl also cannot be used with Mega Salamence or Mega Gengar.
