Rhea redirects here. For the Sonic the Hedgehog fan character, see Rhea the Spider.
Rhea is a young, female speed archaeopteryx living in the hollow mountain with the Hattori Clan and Masanari Black Flowers. She is a flightless archaeopteryx and often serves as a mount to agents of the MBF for ground transportation. Despite being flightless, Rhea is a very swift runner, however, she cannot provide transportation across large distances. She has brown feathers and large, thick wings as well as a long neck.
- Her name derives from the bird of the same name.
