Exedra is a Darkus Bakugan that looks like an eight-headed Hydra with a single eye and a jaw on its chest. Deadly fire breathing blasts disintegrate its opponents. Exedra can transfer power from a teammate Bakugan to itself to increase its battling strength.
Exedra, the Darkus Legendary Soldier, battled Masquerade with an illusion of Alice Gehabich using the most powerful Darkus ability cards, Demon Wizard and Final Wizard. He is defeated by Masquerade with a combo from Dual Hydranoid.
Along with the other Ancient Warrior Bakugan, he battled King Zenoheld and his Mechanical Bakugan Farbros. In the end they are defeated but rather than losing their Six Attribute Energies they entrust them on to the Bakugan Battle Brawlers Resistance Guardian Bakugan. Exedra passes on the Darkus Attribute Energy to Percival, causing him to evolve into Knight Percival.
