Movie
Description
Bellion, a high-ranking Demon Clan member, commands the Six Knights of Black—rogue demons exiled by the Demon King for their anarchic defiance. His gray-skinned visage features piercing red eyes, purple hair (rendered white in anime adaptations), and a crimson ring-shaped mark etched on his chin. During the ancient Holy War, Bellion’s ambition to join the Ten Commandments crumbled when Meliodas scornfully rejected him mid-battle against the Archangel Mael, deeming him a liability. This humiliation ignited Bellion’s obsessive vendetta to overthrow Meliodas.

Earlier, Bellion infiltrated the Celestial Realm, slaughtering Goddess Clan warriors until Mael overwhelmed him. Though Meliodas spared his life, Bellion’s plea to join the Ten Commandments was met with derision. Vowing retaliation, he forged the Six Knights of Black to usurp the Commandments’ influence. At the Sky Temple, Bellion unleashed an Indura—a ravenous demonic entity—but the Great Oshiro defeated him, sealing the Knights within the Egg Rock for three millennia.

When the seal fractured, Bellion reignited his crusade, deploying the Indura against Meliodas, whom he initially failed to recognize. Wielding the Winged Sword, a demon-slaying relic, he severed his own arm to poison Meliodas with its cursed edge. As his Knights fell, Bellion consumed their souls to awaken the Indura’s full power, transforming his arm into a monstrous limb. Despite this surge, Meliodas’s demonic form overwhelmed him. In a final gambit, Bellion detonated Death Burn—a cataclysmic blast—only for Meliodas to reflect it via Full Counter, annihilating him. Bellion’s soul merged with the Indura in death, but the creature was later eradicated by the Seven Deadly Sins and Celestials.

Bellion wields darkness for offense, defense, and telekinesis, regenerating non-lethal wounds. His Blade of Erosion channels corrosive darkness through his sword, while Death Burn conjures volatile blue flames. Though his cunning and power briefly challenged Meliodas, his reliance on treachery and vengeance exposed strategic flaws.

The Six Knights of Black, canonized in the manga but expanded in film lore, serve as Bellion’s instrument of rebellion. His arc epitomizes pride and ambition’s corrosive toll, framing him as a vengeful foil whose hunger for dominance accelerates his ruin within the eternal clash between demons and celestials.
