Seven Deadly Sins vs. Melascula

Seven Deadly Sins vs. Melascula is a battle fought between the Seven Deadly Sins, along with Elizabeth Liones and Elaine, and Melascula of the Ten Commandments.

Prologue
The infamous Seven Deadly Sins begin their journey to the city stronghold, Corand.

Battle
As the Seven Deadly Sins enter Corand, Escanor points out to Meliodas that someone was standing on the other side of the bridge. Such is revealed to be none other then Meliodas's younger brother, Zeldris. Meliodas then charges towards Zeldris, activating his demonic transformation. He then swings his sword and then splits Zeldris's body in two, only to find that this "Zeldris" was an illusion. All of a sudden a voice appears, followed by black figure's, then encasing Meliodas in a Dark Cocoon. Ban, realizing who the culprit is, jumps and attempts to save the captain, only to fail.

Hawk then notices thousands of skeletons laying on the ground, only to see that they begin to rise, muttering curses. The skeletons instantly charge and attack the Seven Deadly Sins, only to be extremely weak, for even Hawk was able to take one down.

Meanwhile, in the Dark Cocoon, Meliodas attempts to break out using Hellblaze, only to be informed that it shall not work, since his Hellblaze is made of dark energy, as well as the cocoon. Only to turn and realize that his attacker is Melescula. Meliodas attempts to strike her, only to see it was an illusion once more. Melescula then informs him that all of his negative energy is being transformed into "something else". Suddenly, the skeletons fighting the Seven Deadly Sins grow stronger. Melescula then explains, that the negative energy is being transferred into the souls posessing the skeletons, called Vengeful carnage.

Due to the sudden power up of the souls, the Seven Deadly Sins now have a more formidable opponent. A single skeleton punches Diane into a building. Gowther attempts to stop the majority of the skeletons with Jack, a technique which stops the movement of nerves in a singular spot which is hit, which only backfires. Merlin then explains to Gowther that the spirits are not moving through nerves, but their anger and hatred.

However, even though the skeletons are now much more powerful, the Seven Deadly Sins begin to unleash more of their true power. King begins to use Chastiefol's true forms, such as Sunflower, and causes a mass explosion destroying quite a few of the reanimated soldiers. Diane then uses 1,000 Stones, and crushes the lot of soldiers. Ban is slowed down greatly as the skeletons stab him constantly, only to have Escanor's aid.

Melascula, shocked, decides to take all of the negative energy that was dispersed among the reanimated soldiers, and place it in one. However, the magic is far too great and such destroys the final skeleton. Suddenly, Merlin senses a odd presence, and then informs the Seven Deadly Sins that the spirits are trying to possess them, so they must hold onto their consciousness. She is too late, and finds that Diane, is now possessed. Meanwhile, back at the Boar Hat, Elaine attempts to go to Ban, and the rest of the Seven Deadly Sins. Only to see that Elizabeth, the goddess, has awakened and is ready to assist her.

Diane (or the spirits possessing her) begin with Dolor's Dance. Merlin then states that the only way to defeat Diane is to attack her, however, King tries to bring her back through words. Diane then kicks King roughly into a rock, and knocks him out. Escanor then punches Diane harshly in the stomach, shattering her armor. Diane then, not hesitating, strikes him with her fist. Gowther then approaches Diane, and activats Invasion. Gowther, inside Diane's head, searches for her to bring Diane back to herself. As Gowther reaches out for her, the vengeful souls grab her and take her further away, throwing Gowther back into the real world.

She then strikes Gowther with Gideon, and sends him flying. Melescula laughs at the scene, as Meliodas is worried. The spirits then start attacking Diane, hurting her body as they control it. Helbram then appears, the spirits instantly spotting him. He states that he's the one who killed them all, so they should take their anger out on him. They then take the helmet and crush it, relieving most of the vengeful spirits. However, many still remain controlling Diane. The spirits begin to attempt an attack, only to be struck my a mysterious wind, along with a strange object piercing Diane and emerging with the spirits, freeing Diane. Diane then turns and spots her to precious friends, Elaine and Elizabeth.

Melascula realizes Elizabeth has awakened, informing Meliodas who now looks worried. Melascula leaves Meliodas so she can fight the sins. Elizabeth heals Diane's and King's wounds, and is greeted with many questions. She then approaches Merlin, formally, and then reveals that Merlin used to refer to Elizabeth as "Big Sis Sis" when she was around 13. However, their reunion is interrupted with Meleacula's arrival. Melascula then transforms into her true form, a large snake. Melascula then attacks Ban and holds him in her mouth, however, Ban holds up her jaws in desperation. Elaine attacks Melescula with Pursuing Whirlwind, to have no effect and to be hit down to the ground.

Elaine gets up once more and charges to Ban and grabs him from between Melascula's jaws. Everyone looks at Elaine, astonished at her new form. Elaine grows wings and her hair grows longer. She hugs Ban and exchanges a moment with him. All of a sudden, the middle of Corand instantly collapses, with a surge of evil and dark energy. Such is revealed that the sinister power is Meliodas. Escanor summons his sword and then approaches Meliodas. Melascula then states that this Meliodas is what they feared back when he lead them, his Assault Mode. Merlin then encases the two in a Perfect Cube. Melascula looks at the Sins, now relieved that the two are trapped in their, unable to harm her.

Ban then jumps and attempts to snatch Melascula's final heart, but is unable to locate it since Melascula is moving it throughout her long body. She then attacks him with her Deadly Poison. Elizabeth then approaches Ban, the poison not effecting her, and uses Invigorate, neutralizing Melascula's poison in an instant. Suddenly, the ground shoots up and attempts to attack Melascula, revealing that Diane is attacking her. Melascula then charges Diane, only to be struck harshly on her head. King then attacks her with Bumblebee. Melascula, overwhelmed, crashes to the ground.

All of a sudden, tornadoes appear around Melascula, which is Elaine attacking her with Tempest Falls. Gowther then jumps and lands on Melascula's head, using Nerve Severance, which disconnected Melascula's nerves, so she cannot move for 10 seconds. Elizabeth then attacks Melascula with Tranquilize, which destroys Melascula's Miasma, showing Melascula's original form, a small poisonous snake. Merlin then catches her and puts her in a test tube for later. The fight has ended.
