The Future Warrior in Black emerges from an alternate timeline where Future Gohan’s failure to shield Trunks and Bulma from the Androids resulted in their tragic demise. Tormented by relentless guilt over his perceived inadequacy, he bargained with Aeos, wielding the Dark Dragon Balls to transform into one of her Warriors in Black. Driven by a need to validate his strength and enforce his vision of a singular "true history," his path briefly converges with Aeos’ destructive ambitions. Physically mirroring Future Gohan, his identity is marked by a missing left arm, a prominent facial scar, and a shadowed hooded cloak. Once shedding the cloak, his battle-worn attire—a black gi with a blue obi, grey undershirt, brown pants, and black boots—fuses Saiyan tradition with austere practicality, mirroring his fractured resolve. Once altruistic, his psyche fractures into brooding obsession, fixated on power as redemption for his survivor’s guilt. Lingering traces of his former self surface sporadically: acknowledging Xeno Trunks’ resilience, wrestling with emotion during clashes. In battle, he adapts a ruthless one-armed combat style, channeling Dark Dragon Ball energy into techniques like the One-Handed Kamehameha. The manga depicts him justifying Aeos’ timeline purge as a brutal necessity, while the anime reveals a conflicted turncoat. Aligning with Xeno Trunks against threats like Demigra, he confronts regret for his timeline’s failures, culminating in a unified Father-Son Kamehameha alongside Goku and Xeno Trunks. His fractured redemption peaks when defeated by Xeno Trunks, shattering his rigid philosophy. He aids allies in pivotal conflicts, harnessing Super Saiyan 2 through darkened power, strategizing with Xeno Goten and Majuub. His final stand shifts from enforcing a singular history to defending all timelines, redefining strength as collective preservation over solitary conquest.
