Cucky (Sonic X)

Cucky is a species that appears in the Sonic X anime series and its comic series published by Archie Comics which first debuted in "Mean Machines". They are a race of non-anthropomorphic game fowls native to Sonic the Hedgehog's world.

Anatomy
The Cuckies resemble white-feathered chickens with a round-shaped head, two large greyish blue eyes, a tiny orange beak, and thick cheeks. Their wings are medium-sized compared to their body, which is at the same size as their head, and possess smooth tail feathers and soft orange feet with three toes on each foot. Additional features include a rather large red comb and a red wattle under their beak.

Anime
At some point, Cuckies began showing up on Earth, presumably due to the Chaos Control irregularities occurring after the Space Colony ARK incident. Despite concerns that their cultures would cause tensions, the Cuckies maintained a peaceful existence alongside the humans until they got sent back to their home planet with the other creatures. However, Dr. Eggman soon returned to threaten the Cuckies with his plans to take over their world.
