Tricloid (original version 'Droa' (ドロア Doroa)) is a Subterra/Haos hybrid Bakugan. She looks a much like a more Subterra Bakugan than a Haos Bakugan. She is one of the combined light and earth world gatekeepers, along with her older sister Rabeeder. She has three eyes. Tricloid and her sister Rabeeder are very close and get very enraged when something happens to the other. She enjoys making things out of mud, making mud balls and even a mud heart for Dan.
