Hairadee (original version: 'Rock' (ロック Rokku)) was a Ventus/Aquos hybrid Bakugan that served Naga. He looked like he is a little bit more Ventus than Aquos. Hairadee strongly resembles a male version of Harpus, being roughly humanoid with feathers on his arms. However, this is offset by having tentacles instead of hair, webbed feet, shark-like teeth and an overall blue and green color scheme.
