Biography: Lord Reacas is an evil wicked Heartless and devoted servant of darkness to the Dark Lord of the Shadows. He is the leader of the Deadly Organization.

When he was a human, Reacas grew up being a slave to a corrupt military army in his home world. However, he secretly used to his advantage as he was good at deception.

Reacas killed the military's leader and took over their base for himself. He began his conquest to take over his world before he had an unfortunate death, that lead him to become a Heartless.

Reacas then came to lean about the Keyblade before he wielded one himself, one that which was granted to him by the Dark Lord of the Shadows along with the power to wield Darkness Magic.

Reacas forms the Deadly Organization as its leader and searches for members that represents the Seven Deadly Sins or even more with one objection: to collect all the hearts across the universe, so they can be immortal.

Reacas is a tall and muscular man with pale skin, black hair with white streaks, and black eyes with red pupils. He wore a black trench coat with a black shirt that has a demonic skull underneath. Black pants with red chain like markings on it, fingerless black gloves, and black boats.

Reacas is capable of wielding a Keyblade of darkness called Hellion Suffering. He can also summon Heartless and demons by his side to fight for him.

Magic: Reacas is capable of wielding Darkness Magic since it represents his sin of corruption. It is said that his power of the darkness could be much stronger than Ansem, the Seeker of Darkness.

Darkness Magic spells;

Dark Rondo: When cast, Dark Magic with horror-stricken faces swirls around his hands, becoming more and more condensed. Reacas can then fire the gathered Magic as widespread blasts, or a dark beam. He can also summon the ghosts from under the ground, heavily damaging the target from below.

Dark Grab: Reacas moves his hands towards the opponent, far away from him. This will prompt a pair of strong, dark-colored arms to appear from a nearby surface and grab the opponent, immobilizing or choking them according to the movements performed by Reacas himself, who, after grabbing the target, is capable of controlling the spell with a single hand.

Dark Vanish: A spell in which the target seemingly implodes from the inside, or is, in any case, forced to vanish through unknown means, leaving only the clothes behind.

Darkness Cage: Reacas creates a sphere of Darkness Magic in his hand, before firing it at his target, releasing several ghosts that wrap around the them, restraining their movement.

Bind Snake: This spell appears in the form of a snake tattoo. The snake winds its way around the target's body, tightening and restricting movement.

Paradise of Sins: Reacas creates a dark sphere that expands until it transitions into multiple tentacle-like entities that rush towards the target, and upon contact, spontaneously erupts. Within, the dark sphere appears to feature the face of Ksitigarbha.

Dark Capriccio: A beam of darkness is fired from his hands, meant to be used as to pierce through defenses. He can also able to manipulate its movement with one hand, cast more than one beam at a time, and even use it as a whip.

Zero Slash: Reacas uses Dark Capriccio as a whip and attacks the enemy.

Dark Deflect: Focusing the incoming attack on his eye, Reacas redirects the incoming spell, missing the intended target.

Dark Enveloping Claw: Reacas summons a dark claw from the ground, which ensnares the target, restricting their movement. By directing the claw at the throat of the target, the user can effectively create a hostage situation.

Dark Moment: Reacas cuts the lights in the room or general area they are in, plunging it into darkness, thereby allowing the user and any comrades they may have to attack, virtually unseen.

Darkness Breath: Reacas charges dark energy and molds it into the shape of a highly destructive tornado, damaging his intended target.

Darkness Blast Bomb: Reacas creates a sphere-like bomb made from dark energy and charges at the enemy at close range. The bomb creates a huge wave of pressure, that throws the target away.

Genesis Zero: Reacas gathers a large amount of Darkness Magic around his fingertips before, ultimately, unleashing it as a wave of countless phantoms that seek to erase the target's soul, and even their very existence.

Darkness God Slayer Magic: Reacas can also wield God Slayer Magic with his darkness.
