Fubuki, also known as Hellish Blizzard, holds the rank of B-Class Rank 1 hero in the Hero Association. She is the younger sister of S-Class Rank 2 hero Tatsumaki, with both possessing formidable psychokinetic powers and jointly recognized as the Psychic Sisters. Fubuki founded and leads the Blizzard Group, a coalition of B-Class heroes aimed at consolidating power through collective effort—a deliberate contrast to her sister’s solitary approach. Driven by ambition and strategic acumen, Fubuki grapples with a deep-seated inferiority complex fueled by Tatsumaki’s overwhelming strength. This insecurity historically motivated her to dominate B-Class rather than advance to A-Class, influenced by Sweet Mask’s gatekeeping at A-Class Rank 1 and her fear of inadequacy in higher tiers. She maintains her position by recruiting lower-ranked heroes, viewing unified strength as a pathway to eventually surpass her sister. Her leadership emphasizes tactical coordination, mentorship, and alliance-building. Her psychic capabilities encompass telekinesis for offense and defense, self-levitating flight, energy suppression, and organic healing. Signature techniques include Hellstorm (debris tornado), Hell Cutter (focused telekinetic blast), and Psychic Barrier—shields that withstand Dragon-level threats like Overgrown Rover’s energy blasts, though at severe personal strain. She demonstrates precision, such as stabilizing Genos’s overheating core during the Monster Association raid despite physical toll. Physically, Child Emperor’s assessment ranks her at average human level (score 19), yet her psychic power reaches city-level potency in combat. Fubuki’s character evolves across key arcs. Initially, she attempts to forcibly recruit Saitama after recognizing his strength, treating relationships transactionally. During the Monster Association raid, she shifts toward selflessness, risking her life to shield allies—blocking Overgrown Rover’s blast to protect Bang and Bomb, and healing Genos. Her pivotal growth occurs in the Psychic Sisters arc when confronting Tatsumaki, declaring her intent to gather trustworthy allies so Tatsumaki "wouldn’t be isolated." She asserts a new philosophy: "I’m gathering strong allies whom both you and I can trust... This time, I can help you in a way you can’t help yourself. Because... I’m a hero!" This resolve impresses Tatsumaki, who acknowledges Fubuki’s maturity. After Tsukuyomi’s infiltration compromises the Blizzard Group’s safety and disables her powers, Fubuki disbands the faction. While many members resign, loyalists like Eyelashes remain, enabling continued operations with a trusted core. She considers restructuring the group under a new identity or maintaining an informal network akin to Saitama’s circle, reinforcing her focus on authentic loyalty over numerical dominance. Key relationships shape her journey. Her dynamic with Tatsumaki evolves from fear and resentment to a determined commitment to support her. With Saitama, recruitment attempts yield to grudging mutual respect and sporadic collaboration. Her rapport with Genos shifts from distrust to reciprocal loyalty after she saves him from core meltdown. She commands fierce allegiance from Blizzard Group members like Lily and Eyelashes, defending them even when mind-controlled by adversaries like Do-S.
