Akuma operates as an unseen antagonist, his presence felt solely through relentless psychological manipulation. He torments Ryu via telepathic communication during Ryu's desert isolation, repeatedly urging him to embrace the Satsui no Hado ("Surge of Murderous Intent") and taunting him about the dark power within his veins, amplifying Ryu's inner conflict toward a breaking point.

His motivation stems from his pursuit of ultimate strength. Akuma views Ryu as a worthy opponent hindered by rejecting the Satsui no Hado. His taunts dismiss any path besides raw power as "foolishness," reflecting his nihilistic philosophy and desire to force Ryu into a transformative battle. He remains a cold, relentless force fixated on awakening Ryu's darkness to forge a supreme adversary.

Akuma's characterization draws on Buddhist iconography. His dialogue and role mirror the Nio guardian Misshaku Kongō, embodying overt power, contrasting his brother Gouken's latent strength, symbolizing his persona as a destructive yet disciplined entity. His moral code dictates he avoids direct confrontation until Ryu embraces the Satsui no Hado, adhering to his principle of battling only opponents he deems worthy or ready.

This manipulation directly triggers Ryu's temporary submission to the Satsui no Hado during Crimson Viper's ambush. After Viper tortures Cammy, Ryu succumbs to Akuma's earlier provocations, unleashing the dark power and driving Viper back, highlighting Akuma's corruptive success before Sakura intervenes.

Akuma's iconic Street Fighter IV-era design—red hair, dark gi with torn sleeves, prayer beads, and the "ten" (天) kanji—informs his representation during this timeline, though not visually depicted in the anime. The narrative implicitly positions him as a foil to Seth; while Seth seeks to weaponize the Satsui no Hado for technological domination, Akuma values it as a pure martial philosophy, embodying the conflict between natural human darkness and artificial power.
