Geten (full name Himura Geten, alias Iceman), from the My Hero Academia canon on the official Fandom wiki, is a hardcore ideologue of the Meta Liberation Army (later Paranormal Liberation Front). He embodies extreme meritocracy based on Quirk strength: he believes society should be hierarchical with the most powerful Quirks at the top, and personal worth is measured almost solely by how strong and honed one's Quirk is.
Key traits from canon:
He's obsessively dedicated to training his Ice Ply (Hyōsō) Quirk for years, skipping normal life (no school, constant self-improvement) because he sees raw power as the ultimate value and survival mechanism.
He's deeply grateful to Re-Destro for "granting him more power" (likely via resources, training, or awakening opportunities), showing he values external boosts that amplify strength.
He awakened his Quirk during intense conflict (Re-Destro burning his hand), gaining temperature control over ice/water, making it far more versatile and destructive (city-scale range, manipulating existing ice/water into weapons, defenses, or platforms).
He's proud, arrogant about his own power, and dismissive of those he sees as weaker or reliant on lesser means (e.g., clashing ideologically with Dabi over Quirk philosophy, mocking reliance on fire when ice can counter it).
Rei Todoroki (née Himura) has the Frost Quirk, which lets her generate and manipulate ice from her body at will. It's a strong emitter-type ice Quirk, but she never trained it aggressively—her life was shaped by quirk marriage to Endeavor, trauma, abuse, mental breakdown, and institutionalization. She used it defensively/offensively in flashbacks (e.g., scarring Shoto), but it's portrayed as potent yet emotionally burdensome, not something she honed to its limits.
Regarding how Geten would feel about Rei (sharing the Himura surname/clan ties, both ice users):
Geten would almost certainly feel a mix of envy and disdain toward Rei, leaning heavily into envy over her raw potential but tempered by contempt for her "wasted" life.
Envy factor: Rei's Frost is a pure, innate ice generation Quirk—creating ice from nothing, potentially unlimited output if trained (similar to how Shoto's ice side scales massively). Geten's Ice Ply relies on manipulating existing ice or water sources (he needs moisture/ice nearby to go all-out, though awakening helps). In a direct comparison, Rei's ability to spawn ice freely could be seen as "superior" in versatility or sustainability in dry environments. Geten, who idolizes Quirk strength above all and trains relentlessly to maximize his, would envy someone born with what he might view as a "better toolkit" for ice dominance, especially if he learned she was from the same declining Himura bloodline (which canon ties to quirk marriages and selective breeding for strong ice Quirks).
Disdain/contempt factor: Rei never pursued power maximization—she was a civilian housewife, broken by Endeavor's abuse, and her Quirk use was sporadic/trauma-linked rather than trained to god-tier levels like Geten's lifelong grind. Geten would see this as squandering a gift: someone with strong ice heritage who could have been a top-tier powerhouse but instead became weak, passive, and institutionalized. His worldview doesn't value "potential" alone—it demands active honing and dominance. He'd likely view her as a failure or embarrassment to the bloodline, someone who didn't "earn" her power through effort, making any envy bitter and resentful.
Overall, Geten would be envious of Rei's Quirk's inherent advantages (free generation vs. his manipulation dependency), but that envy would fuel scorn—he'd see her as proof that even strong Quirks mean nothing without relentless pursuit of strength, aligning with his merit-based ideology. If they met (e.g., in a hypothetical where Geten learns of the Himura-Todoroki connections), he'd probably mock her harshly while internally seething at what she "could have been" if she'd trained like him. This fits his canon personality as someone who measures everyone by Quirk power output and effort, not birthright or unused potential.
