Athena is the olympian goddess of war and wisdom, and can transform into a subterra bakugan. She is a mother-like figure to Cassandra, calling her "Eevee Chibi" all the time, and teaching her some tricks with the katana. When it comes to war plans, though, she always thinks, "I can do better than that!" her weapon is her sword and sheild. She is the daughter of Zeus and Metis, and she also assists Dan and Drago on how they can help Cassandra with her predictions, which she finds out that they also have visions of the future. She appears in Bakugan: Cassandra and the Crimson Core Brawlers.
