Hector's abrupt awakening in a 2004 Marvel Universe, into a body mirroring his own 2022 self, was a disorienting plunge into a subtly altered reality. The subtle differences in his room, the antiquated computer, the chilling realization of a temporal shift, all coalesced with the discovery of the Essence of Gacha. This omniversal cheat system, plucked from his past life's pop culture, offered immediate, boundless power: character assimilation for skills and traits, summoning for loyal allies, and a vast array of items. His first strategic rolls yielded a formidable initial arsenal, mixing Marvel-specific assets like Miles Morales, MCU Loki, and the Thor Bio-Mech Suit, with broader fictional powerhouses such as Funny Valentine (complete with his D4C Stand) and the tactical genius of Batman. Hector wasted no time, experimenting with D4C's dimension-hopping, the Source of All Living Matter's rapid regeneration, and the Thor Suit's superhuman durability, instantly elevating him beyond baseline humanity. Yet, this intoxicating surge of power was brutally interrupted by the sudden, suspicious death of his parents. This personal tragedy, coinciding with his 16th birthday, shattered any remaining illusions of a peaceful transition, forcing Hector to confront the inherent dangers of his new world and the immediate, desperate need to wield his nascent abilities for self-preservation and burgeoning vengeance. The Gacha was no longer a mere game; it was his sole lifeline in a universe that had just claimed his family.

The raw grief over his parents' death rapidly calcified into a steely resolve, fueled by the accelerating assimilation of Funny Valentine and Batman. Hector's intellect sharpened, his combat instincts honed, and a profound paranoia took root, immediately leading him to suspect foul play. His initial investigations, coupled with the subtle cues of Alexander Belluci, his uncle, pointed towards a deeper conspiracy. Seeking emancipation to gain control of his inheritance, Hector shrewdly approached Nelson and Murdock, subtly manipulating the situation to expose his uncle's greedy machinations. The conspiracy escalated when Kingpin's thugs invaded his home, seeking to eliminate him. Hector, now a nascent strategic powerhouse, brutally dispatched the intruders, marking his first kill and framing the Punisher to maintain his anonymity. This grim act solidified his pragmatic, morally gray approach: ruthless efficiency for self-preservation and calculated vengeance. With the immediate threat contained, Hector, now a killer and strategist, planned a temporary retreat to Brazil, a strategic pause to consolidate his burgeoning powers and prepare for a calculated return to dismantle the criminal empire that had orphaned him.

In the relative calm of Brazil, Hector completed the assimilation of Funny Valentine and Batman, fully integrating their skills and personalities. A calculated strategic leap saw him use a Shonen Travel Ticket, transporting himself to the My Hero Academia universe during the climactic All Might vs. All For One battle. His primary objective: steal All For One's unique quirk. Exploiting the villain's weakened state, Hector successfully acquired the coveted power. This was merely the first step; using multiple Power Boost Cards on All For One, he triggered a miraculous fusion with his existing Power Copying and latent X-gene, birthing his Omega-level mutant ability: Power Manipulation. Now capable of stealing, copying, and cultivating any non-innate power, Hector embarked on a ruthless "buffet" of quirks, publicly "stealing" One For All and framing Midoriya to sow chaos. He systematically defeated multiple top-tier heroes, including Star and Stripe, employing advanced Haki and his rapidly expanding power set, establishing a terrifying, villainous persona known as "Dis." This calculated rampage was designed not for true villainy, but to rapidly accrue power and experience, leaving hero society in disarray as he prepared for his triumphant return to Marvel.

Hector's month-long tenure as "Dis" in the BNHA world was a whirlwind of strategic villainy and unexpected personal growth. He systematically "buffeted" quirks, trained with the fragmented consciousnesses of One For All users and All For One himself, gaining invaluable combat and leadership insights. He secured Gigantomachia's loyalty, transforming the giant into his first card-summoned subordinate. More profoundly, Hector rescued Eri, healing her physical scars and guiding her in controlling her devastating quirk, finding an unexpected moral anchor in her innocence. His actions exposed the Hero Commission's dark secrets and forced Endeavor to confront his family's tragic past, initiating a societal reckoning. Before his departure, Hector orchestrated a complex plan: returning all stolen quirks (except One For All, repurposed for a greater good), establishing a functional cure for Quirk Singularity, and publicly exposing hero society's flaws, forcing it to rebuild on a more honest foundation. His final act was a deeply personal one, a romantic night with Lady Nagant, forging a bond and potentially leaving behind a child. Returning to Marvel, Hector was an immensely powerful, strategically refined, and morally complex individual, carrying not only vast new abilities but also the weight of profound attachments and a complicated legacy.
