Sparrow is a young, male stealth archaeopteryx living in the hollow mountain with the Hattori Clan and Masanari Black Flowers. He often serves as a mount to top agents of the MBF for transportation. His head is black and white, his wings are brown and orange and his stomach is white. Sparrow is very social and friendly, especially to other archaeopteryxs and, occasionally, humans. He is somewhat smaller than other archaeopteryxs and enjoys eating nuts.
- His name derives from the bird of the same name.
