Blitz Fox is a Pyrus elemental Bakugan with a kitsune form, serving as the guardian Bakugan to Athena. Her Nanogan partner is Scorcher. She initially appeared containing Pyrus energy and combating invasive plants within a city. Blitz Fox engaged in battles against multiple opponents including Drago, Trox, Pegatrix, Howlkor, Hydorous, and Pharol. Confrontations with Drago showcased her significant combat abilities yet resulted in losses. She also joined other Bakugan against a rampaging Darkus Bakugan, facing defeat. A notable struggle emerged during training battles against Pegatrix, where Blitz Fox repeatedly evolved into Strength Mode instead of mastering the desired Speed Mode, causing frustration for both her and Athena. This culminated in a battle against Drago where her failure to achieve Speed Mode led to increasing violence and loss of control. Intervention from another Bakugan ended the battle, after which Blitz Fox expressed remorse. Subsequent battles demonstrated her successful use of Speed Mode against opponents like Warrior Whale and Drago. Blitz Fox later collaborated with Pegatrix to combat a rampaging Haos Goril, evolving into Speed Mode during the fight. She appeared briefly as one of several Bakugan captured in Ventana before being released. Her combat techniques include Smokescreen, creating an obscuring barrier; Searing Slash, involving scorching claw strikes; Fire Spiral, generating a spiral tornado; Inferno Rift, summoning magma rocks; Lava Bombs, launching lava projectiles in Strength Mode; Fireball Blitz, transforming her into a fireball in Speed Mode; and Blazing Lasso, trapping opponents in a fire vortex in Speed Mode. Her Nano-Gear technique is Magma Scorcher. Blitz Fox was the second Bakugan to achieve Strength Mode and the third to achieve Speed Mode. Her evolution patterns mirror Pegatrix, becoming bulkier in Strength Mode and more slender in Speed Mode compared to her base form. In the Japanese anime version, Blitz Fox is characterized as male.
