Cardinal is an eldery, male power archaeopteryx living in the hollow mountain with the Hattori Clan and Masanari Black Flowers. Due to his old age, he no longer serves as a mount to MBF agents for missions. His plumage is bright red with a patch of black around his beak, which is a paler red than his feathers. He is somewhat territorial and often communicates through song in whistles.
- His name derives from the bird of the same name.
