Pokémon Battle Feature Figure Aerodactyl 11 cm

Aerodactyl is a reptilian, bipedal prehistoric Pokémon that resembles a pterosaur with several draconic features. It has small sharply pointed ears, narrow dark green eyes, a ridged snout, a gaping mouth, and a strong lower jaw full of serrated fangs. Its body is covered in light blue-gray skin and it has large, violet membranous wings. The clawed hands at the end of each wing allow it to grasp objects. There is a hump-like ridge with a spike on its back, and it has a strong tail with an arrow-shaped tip. Its talon-like feet have two toes in front and one in the back, and are capable of scooping up and tightly clutching its prey in flight.

Aerodactyl's serrated saw-like fangs and ferocious attitude were very imposing in its time. Its fangs can rip out throats and tear through the skin of any Pokémon to pieces, even Steel-type Pokémon. By spreading its wings, Aerodactyl is believed to have flown by gliding through the skies, freely letting out its high-pitched cries. However, it is slow to walk on land. It liked to nest in the mountains, where it enjoyed both safety and seclusion. Aerodactyl lived in prehistoric times, and was theorized to become extinct thanks to a giant meteor impact. It was restored in modern times using genetic material extracted from amber; some casualties occurred during these attempts. Even still, this restoration is not considered perfect.

Forms
Aerodactyl can Mega Evolve into Mega Aerodactyl.

As Mega Aerodactyl, its eyes turn bright green and parts of its body turn to stone, which some researchers believe to be its original appearance before fossilization. It grows larger and sprouts jagged black spiky rocks all over its body: five spikes at the wrist joint of each wing replacing its hands, three small spikes along its tail, one spike on each ear, and a long spike on its chin. The spike on its back and its rear talons have also become black and stony. Rocky plates cover its eyebrows and the corners of its jaw. Similar stone ornaments are present on its chest on its torso: two small ridges flanking a longer ridge.

The power of Mega Evolution allows some of Aerodactyl's dormant genes to reawaken. The rocks on Mega Aerodactyl's body are harder than diamond. Because of the burden of Mega Evolution, Mega Aerodactyl is fiercer and more irritable than before. As a result, Mega Aerodactyl attacks anything that moves.
