Alice Gehabich hails from Moscow, Russia, residing with her grandfather Dr. Michael Gehabich after her parents' presumed death. Homeschooled due to lacking nearby schools, she masters Bakugan strategies yet avoids direct battles from self-doubt, fear of losing, and aversion to violence. Instead, she serves as the Battle Brawlers' primary strategist, delivering vital tactical guidance. Her reserved, polite nature makes her one of the group's most mature members alongside Shun Kazami. She prioritizes team harmony, detects concealed emotions like Shun's worries, bonds closely with Runo Misaki, protects Dan Kuso and Shun, and treats Marucho Marukura as a younger brother. Exposure to the Silent Core's negative energy through her grandfather's interdimensional device unconsciously transforms her into Masquerade—a cunning, aggressive male alter ego with spiked blond hair. As Masquerade, she becomes the world's top-ranked brawler and the team's antagonist, wielding Darkus Bakugan like Dual Hydranoid (evolving into Alpha Hydranoid) and banishing defeated Bakugan to the Doom Dimension. Alice recalls nothing of these episodes despite clues like unexplained absences. Episode 38's revelation fractures trust, especially with Shun, who blames her initially. Guilt-ridden, she isolates with her aunt and uncle. Witnessing Dan Kuso's peril in Vestroia spurs her development. Encouraged by Klaus von Hertzon, she briefly becomes Masquerade one final time to rescue Dan. The shattering mask frees her from Naga's influence, allowing Masquerade to relinquish control permanently. Alpha Hydranoid transitions into her loyal Guardian Bakugan. Rejoining as a Darkus brawler, she fights with newfound resolve despite lingering trauma, participating in the first season's climax against Hal-G and Naga using strategic moves like the "Trident of Doom" ability card. In *New Vestroia*, Alice supports by reactivating the interdimensional transporter with her grandfather and sheltering defected Vexos member Lync Volan. Receiving a Darkus gauntlet from Mira Fermin reignites her brawling. Battling Vexos agent Shadow Prove and his mechanical Bakugan Hades, she resists Masquerade's spectral temptation to transform, relying on her own strength alongside Chan Lee and Fortress. Though defeated, this confrontation solidifies her confidence in separating from her alter ego. Her Bakugan Hydranoid is petrified in Prince Hydron's collection but later restored. Later seasons (*Gundalian Invaders*, *Mechtanium Surge*) reduce her role to appearing only in Marucho-viewed photographs, maintaining team connection without active interdimensional involvement. Physically, she has waist-length ginger-orange hair and hazel-brown eyes, wearing a yellow dress with green accents initially, then a lavender hoodie with pink top and yellow skirt in *New Vestroia*. Her personality blends kindness with strategic intellect, though she shows gullibility trusting Lync Volan. Her bond with Hydranoid reflects mutual respect and loyalty, evolving beyond its origin as Masquerade's weapon.
