Strix is an adult, male power 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. Strix's feather pattern largely resembles tree bark with its light brown color. His face is much like an owl's in that his feathers curve up and he possesses a smaller sized beak.
- His name derives from the Ancient Roman and Greek word fo owl and is based on the mythological creature of the same name.
