Abyss

How Abyss joined the Tourney
Tracking SoulEdge once again, Abyss decided to confront SoulCalibur as well. He hoped that he may be able to obtain both of them at once; but he discovered that SoulEdge, which was stolen the jungle wanderer, Blanka, had lost half of its mass and had become sealed, and that SoulCalibur had been infected by evil, gradually losing its power. In order to restore both blades to their power and complete his plan, he revived the will of the evil sword in the form of a new Nightmare which had no host. In order to aid the sword in his restoration, he needed to create conflict within the mind of Siegfried, the bearer of both blades, by leading survivors of Nightmare's past massacres towards him. If SoulEdge regained its power, so would SoulCalibur in order to confront him.

How to Unlock
The player must complete one of the following requirements to unlock Seong Mi-na: For both of these options, the player must brawl Abyss on the Delfino Plaza stage. After defeating Seong Mi-na, the announcer will say "Someone else has joined the Tourney!" after a Smash Ball appears on the lower-right corner of the screen with a message saying "You can now use Yun-seong's best friend, Seong Mi-na. Does Trust lie in your soul, too?". You will then see him to the left of Deathborn, to the right of Zasalamel, above Cassandra, and below Samurai Goroh on the Character Select Screen.
 * Play 354 matches in the Versus Mode.
 * Using Zasalamel, finish Classic Mode.

Cosmic Embryo (Neutral)
Abyss says "IT'S OVER!" and charges up energy in his hand. This move can be charged. With maximum power, the energy ball is as large as many other Smash Bros. Tourney participants and it causes 35% damage.

Gate of Kutoo (Side)
Abyss says "GOODBYE!" while floating in the air with his weapon spinning in front of him before firing it at the opponent, like a boomerang.

Teleport (Up)
Abyss quickly vanishes and reappears in a different location, depending on how the user tilts the Analog Stick.

Void Nova (Down)
Abyss says "YOU FOOL!" and uses a jet-black magnet he used by drawing in opponents while dealing about 33% damage.

Ereshkigal the Ruthless (Hyper Smash)
Abyss stands up with Irkalla in the air, says "May you sleep FOR ETERNITY!", and then meteors fly down from the sky, hitting all his opponents.

Gate of Meslam (Final Smash)
Based on Zasalamel's Soul Calibur IV Critical Finish, Abyss knocks one opponent back while saying "Accept your fate!" and starts drawing the Super Smash Bros. series symbol in the air. A void appears behind the stage and Abyss throws them into it, shouting "Vanish INTO THE VOID!", and ending his Final Smash with a "DISAPPEAR!" as his opponent reappears with approximately 300% damage.

Victory Animations

 * 1) Abyss does a horizontal swipe with Irkalla, then he holds it up, saying "Let the power of Hellfire sink into your soul.".
 * 2) Abyss flourishes Irkalla and poses with it by his side while saying "This is absurd! I SHALL BREAK YOU LIKE A TWIG!".
 * 3) Abyss turns and spins Irkalla while saying "Your end is here.", then he hits Irkalla against the ground.
