Vree are an advanced alien race. Vree are relatively small humanoid beings with large black eyes, bulbous heads, and smooth hairless skin. Despite their slight frame, Vree are very tough. Their bodies are entirely supported by cartilage and muscle. They appear similar to, but are distinct from, both the Streib and the Shadow Surgeons, two races who serve the Shadows. The Vree joined the Axis of Empires.
