Rafe, a Neathian Haos brawler of the Castle Knights military order, alternates between a human guise—marked by short blue hair, purple eyes, and gray-and-orange robes layered over a white shirt, blue pants, and gray boots—and his true Neathian form, characterized by blue skin, large purple eyes, and the Castle Knights’ uniform. Dispatched to Earth with Paige under Princess Fabia and Ren Krawler’s orders, he collaborates with the Battle Brawlers to master combat tactics while countering threats. His Guardian Bakugan, Wolfurio, fights alongside him. Initially dismissive of Marucho’s battlefield contributions, Rafe revises his opinion after the latter’s strategic brilliance secures victory in a Capture the Flag challenge. He apologizes to Marucho and seeks mentorship under him, forging a respectful teacher-student bond. Rafe’s tactical acumen and loyalty shine during clashes with Silent Strike, Chaos Bakugan, and Mag Mel’s forces. He aids in repelling Chaos Bakugan raids on Bakugan Interspace, supports the Gundalia invasion, and acquires the Haos Swift Sweep Mechtogan enhancement for Wolfurio during the final battle against Mag Mel, tipping the conflict in his allies’ favor. As a mediator, he persuades Dan Kuso to rely on his team during Drago’s power struggles and later reunites scattered teammates in Mag Mel’s territory. His partnership with Paige endures, their coordinated strategies proving vital in defending allies. After Mag Mel’s defeat and the resolution of Mechtogan Titan threats, Rafe’s story concludes without explicit detail, though he presumably returns to Neathia alongside fellow Neathians.
