Klaus Von Hertzon

This collector from Germany is known for his passion for Bakugan and other artifacts like suits of armor, which he proudly displays. His elemental affinity is Aquos, and he shares a deep connection with his Guardian Bakugan, the Aquos Sirenoid. A notable aspect of his story involves a rivalry with Marucho, stemming from a significant battle where he sent Preyas into the Doom Dimension.
