Sephiroth/Dissidia (PSP)

Sephiroth is one of the villains fighting for the side of Chaos in Dissidia Final Fantasy. He has little interest in planning and working alongside his allies and instead focuses his attentions on defeating Cloud on his own.

Attire
His outfit is a modification of the one from the Final Fantasy VII universe, featuring some changes in order to make it similar to Amano's artwork, such as a belt around his coat and a sash on one arm, as well as completely new pauldrons. For his alternate costume, he has his shirtless appearance as seen in the final scripted battle of Final Fantasy VII. His crystallized version is cyan in hue.

Destiny Odyssey I
Warrior of Light encounters Sephiroth, who has just wounded Firion and stolen his Wild Rose. The two fight and the Warrior wins. Sephiroth then asks why the Warrior is fighting, and the Warrior tells him that he is simply trying to end the war. However, Sephiroth thinks the Warrior's in the war for enjoyment before he leaves, sensing it's time to give Cloud what he wants.

Destiny Odyssey V
Afterward, the Emperor and Ultimecia approach him asking for an alliance to rule over all, even Chaos. Sephiroth declined and was about to fight the conspirators when suddenly, the Emperor noticed Bartz spying on them, thus giving Sephiroth the opportune moment to leave the battle and continue his manipulation of Cloud.

Destiny Odyssey VII
Sephiroth converses with Garland about memories before going to see Cloud, who refuses to fight him because there is no meaning. Sephiroth calls Cloud a puppet before producing a Wild Rose, meaning that he has wounded Firion. This angered Cloud, and Sephiroth taunts him to go after him. He soon crosses paths with fellow Chaos minion, Golbez, it would seem that Sephiroth had figured out that he was seeking the light and helping his brother, he then taunted Golbez about his need for light saying that in time, the light of Cosmos will burn him. He later crosses paths with Cloud in the Planet's Core, Sephiroth explains why Cloud is a puppet with no will or motivations of his own, simply waiting to be given a command. Declaring facing Sephiroth was done on his own free will, Cloud fights and defeats him. When Cloud retrieves his Crystal, Sephiroth says it was only through his manipulations that Cloud got as far as he did, and he will continue to manipulate him in the future.

Shade Impulse
Sephiroth is fought one last time by Cloud. He once again presses that he is Cloud's manipulator, saying that he is infected with a disease: despair. After the ensuing battle and his defeat, Sephiroth declares that even though Cloud has no ties with him, Sephiroth will remain as a shadow within Cloud's heart and that he will always control him, no matter what he may think.

Battle
In battle, Sephiroth is described as a "Blade Master" and so, he constantly barrages his enemies with his swift sword swings. A single strike will in fact leave behind bands of energy that strike multiple times. Also, he has access to spells, such as Shadow Flare and Meteor, and his Octaslash DMW appears as an HP attack.

Sephiroth's Brave attacks are unique in that many of them consist of many repeated strikes at once. While pressing Circle again will continue the combo, pressing it too soon will prevent Sephiroth from finishing the first strike before moving on to the second, minimizing overall damage. Timing is crucial to maximizing Sephiroth's Brave draining.

EX Mode
Sephiroth's EX Mode is called "Reunion", in which he gets a single black wing on the right side of his back, similar to his appearance in Advent Children as well in the Kingdom Hearts series. In EX Mode he gains the ability to glide, and a variation of Heartless Angel, which reduces his opponent's Brave Points to 1 by pressing R and. While it has a long casting time, it is faster than Golbez's similar Black Fang and Ultimecia's Time Stop.

His EX Burst is Super Nova, where the player repeatedly taps to fill up a limit meter. If the limit meter is filled up, Sephiroth knocks the opponent into the exploding sun. If the meter is not filled, Sephiroth merely executes a normal sword slash. In the full version of the move, Sephiroth stands in front of the fire in a similar fashion to the way he stands among the burning village during the Nibelheim Incident, his trademark scene.

Equipment
Sephiroth can equip the following: Helmets, Light Armor, Heavy Armor, Shields, Gloves, Katanas, and Polearms.

Allusions

 * Sephiroth's attack Prison Gate is an aerial downward stab, and is based on the attack he used to kill Aerith Gainsborough.
 * The disease Sephiroth mentions in Shade Impulse references the worldwide pandemic he caused in Advent Children, Geostigma, which Cloud was also infected with.
 * According to Sephiroth himself, he killed himself in the previous war against Cosmos in order to ascertain the true nature of life and free his spirit from flesh to become more powerful. This is a reference to the Nibelheim Incident, where Sephiroth was "killed" and traveled the Lifestream, emerging years later as a more powerful being.
 * One of Sephiroth's victory quotes is "I will never be a memory," the same quote he used after the last battle in Advent Children, which ironically, his losing quote in the said movie.
 * Sephiroth's version of Super Nova appears to be primarily based on the more famous North American and International version of the attack, which begins with the equations seen here, then features a comet impacting into the sun and destroying the solar system. The less famous Japanese version merely involved a distant explosion with Jupiter and its moons in the foreground.
 * Sephiroth was featured in the first trailer, emerging from the fissure of magma that would later be revealed to be Chaos. Here, he prepares to face off against the Warrior of Light, standing in front of the magma before a close-up of his face is seen, reminiscent of his infamous scene from the Nibelheim Incident.
