Astrodactyl

Astrodactyl is the Omnitrix's DNA sample of an unknown species from Terradino.

Appearance
Astrodactyl resembles a cross between a pterodactyl and a glider. He has a beak like mouth. His wings are rather small and resemble a glider which are connected to a 'jetpack' like structure on his back. He has a large yellow beak, green eyes, red skin, black and green clothing on his shoulders and waist, green braces around his wrists and ankles, and yellow wings. His wings are also retractable.

Astrodactyl wears the Omnitrix symbol on his left shoulder.

Powers and Abilities
Astrodactyl has the ability to fly with his 'jetpack'.

Astrodactyl has some kind of internalized star power, that he can use as propulsion flyer and different forms of weapons. The weapons shown are energy whips, a propulsion effect from his jetpack, and energy beam from his mouth.

According to Derrick J. Wyatt, Astrodactyl can survive in the vacuum of space.

As shown in Collect This, Astrodactyl was shown to have a degree of enhanced strength, as he was able to rip off goo that was difficult for Ben and Rook to get off.

Weaknesses
In A Fistful of Brains, it is revealed that Astrodactyl is vulnerable to electricity.
