Thrasher is an adult, male 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. As a result of his short temper and desctructive nature, he is rarely put on stealth recons. Instead, he is sometimes assigned to attack missions.
- His name derives from the bird of the same name.
