Resembling pterodactyls, from which they derive their name, the Pteras have round blue bodies with a yellow rim on their torso's top and rear. They also have a gray cable-like neck with a pointy blue head, black eyes, and a long blue beak with a yellow lower jaw. They also have wings that are split into three segments with yellow circles on the bottom of each wing segment. Lastly, they have a gray cable-like tail with a pointy blue end.

Game appearances

In Sonic Rush Adventure, the Pteras appear as enemies, They are encountered in Plant Kingdom, Hidden Island 6, and Hidden Island 7. In gameplay, they fly back and forth within their designated flying space.
