Sephiroth's bio

(Appearence)
Sephiroth, in all his appearances, wears a long black coat with silver pauldrons, black boots and black clothing. The top of his clothing underneath his uniform is split to reveal his chest, covered by crossing leather straps. Sephiroth's hair is long and silver, a contrast to Cloud's blond spikes, with his bangs parted to either side of his face. In Crisis Core -Final Fantasy VII-, his bangs are noticeably shorter than in any of his earlier appearances. Beyond his clothing and hair, Sephiroth is known for his green cat-like eyes and the Masamune, his seven-foot long katana he is rarely seen without. His battle stance with the sword is to hold it over his left shoulder with the blade curving downward. Sephiroth usually wields the Masamune two-handed. In later appearances a single black wing emerges from his right shoulder.

(Personality)
Sephiroth's personality is one of cold ruthlessness. Prior to his madness, he was not particularly anti-social, as he has friends in Crisis Core -Final Fantasy VII- and willingly tells Zack and Tifa about Mako and Materia on Mt. Nibel. All the same, his cold exterior and professional attitude turn people away. Sephiroth is intelligent and respectful to those he deems worthy - he considers Professor Gast Faremis a great scientist, but looks down on Professor Hojo and describes him as "a walking mass of complexes". In Crisis Core Sephiroth maintains an outwardly professional demeanor, but is loyal and friendly to a select few, and has a dry sense of humor. Sephiroth is confident to the point of arrogance, but as the strongest SOLDIER alive, it could easily be argued he has the right to be. Well-spoken and somewhat graceful, Sephiroth is universally calm, collected, and in control. He can be frustrated and caught off his guard, but this rarely happens.

Following his fall into insanity, Sephiroth retains most of the above personality traits, but becomes murderous and vengeful. He also develops something of a messiah complex, proclaiming several times he is "the chosen one", destined to lead the Planet and become a god. In Dissidia Final Fantasy, Kefka calls him "Just another sadist with a god complex. Like THAT'S anything special!". His intelligence has increased vastly following his time in the Lifestream where he absorbed the knowledge of the Ancients. At one point, Sephiroth even says he is greater than the Ancients. He has become highly cruel and delights in mentally torturing Cloud, and in Advent Children, in one of his iconic lines, asks Cloud what he cherishes so he may simply take it from him. Sephiroth is fiercely devoted to Jenova and her cause, even though her body serves as little more than his avatar. However, it is also stated that he himself is an agent towards Jenova's will.

Interestingly, in Dissidia, there was at least one hint that he may have some sadness despite his nature, as Cecil Harvey tells Sephiroth before fighting him that "there is sorrow in [Sephiroth's] wintery eyes."

(Ablities)
Sephiroth is a master swordsman and has superhuman strength, agility and reflexes. He is able to produce beams of energy by swinging his sword, dash past or up to opponents in the blink of an eye, and can effortlessly cut through solid metal and concrete with his signature weapon, the Masamune. He has great magical abilities, and is equipped with a full set of Mastered Materia in Final Fantasy VII. In Crisis Core he is able to teleport, the only Final Fantasy game where he can do this, but he also has this ability in the Kingdom Hearts series. Zack Fair, Genesis Rhapsodos, Elfé, Lightning, and the Warrior of Light have been able to battle Sephiroth competently, but none have actually defeated him at his full potential - he eventually overpowers Zack, Genesis and Elfé, and is it implied he was holding back when facing Lightning and the Warrior of Light. Only Cloud has shown the consistent ability to best Sephiroth in battle across his various appearances.

Following his immersion in the Lifestream Sephiroth gains the ability use magic without the need for Materia, and can manifest the Masamune from the Lifestream by willing it to appear. Having taken over Jenova he is able to shapeshift her cells into his visage and other forms. This allows Sephiroth to remain "alive" in a sense even when dead by morphing Jenova's cells into a new body for himself to act through from within the Lifestream, but his ability to do this seems limited. Sephiroth also has a measure of psychic abilities, able to read minds, project illusions, and levitate objects and people. As an extension of his control over Jenova, Sephiroth is able to control the "negative Lifestream" composed of those killed by Geostigma, as shown in Advent Children. In Advent Children Sephiroth has the ability to fly, and in his EX Mode in Dissidia has the ability to glide using his wing.

Sephiroth's trademark attack is Supernova, his ultimate attack when faced as Safer∙Sephiroth. Crisis Core and Dissidia present Supernova as his Limit Break. Sephiroth's other trademark attacks are Heartless Angel, a move that drains the opponent's HP to a single point, Octaslash, a sequence of eight sword attacks, and Shadow Flare, a barrage of dark energy orbs. In Kingdom Hearts and Dissidia, he is also able to use Meteor.

(Etymology)
Sephiroth is named for the (medieval Hebrew form of Sephirot). Sephiroth is a plural noun in Hebrew; the singular is Sephirah (also spelled Sefira). The Sephiroth are described in the Kabbalah as the manifestations of God that allow Him to manifest in the physical and metaphysical universes, referring to Sephiroth's simultaneous existence in the Lifestream and the Planet, and his manifestations through Jenova.

Sephiroth also means "counting" (of numbers), which can be attributed to the Sephiroth Clones. Sephiroth's penultimate form, Bizarro∙Sephiroth, is a mistranslation, and "Rebirth Sephiroth" would be much more apt.

It is often believed the name Safer∙Sephiroth is a mistranslation, similar to how Helletic Hojo should have been translated as "Heretic Hojo." A common rumor is that "Safer" is a misspelling of "Seraph" (שרף) due to Safer∙Sephiroth's angelic appearance. A Seraph (plural "Seraphim", שְׂרָפִים) is described in the Hebrew Bible as being a humanoid angel with six wings:

"Above Him stood the Seraphim; each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew."
Safer∙Sephiroth could easily be seen as a Seraph, with a seventh wing in place of his arm. However, the origin of the name Safer∙Sephiroth is Hebrew; the boss's name as written in Japanese is "セーファ・セフィロス," or "Sēfa Sefirosu"; note that "safer" can also be transliterated as "sefer," "sapher," and "sepher." "Sepher" (סֶפֶר) is Hebrew for "book;" thus, Safer Sephiroth (Sefer Sfirot) literally translates to "Book of Numerations." However, it more likely refers to the 10 Kabbalistic Sefirot, the ten aspects of creation according to Jewish Mysticism.

(Trivia)
Sephiroth is the only SOLDIER 1st Class who has cyan eyes instead of blue.

Sephiroth made an appearance in the LeetStreet Boys music video for "Yuri the Only One" dancing to the lyrics of "Sephy's Mom has got it going on", not only a parody of the song "Stacy's Mom," but also referencing Jenova and his belief she is his mother.

During the scene in which he kills Aeris, when Sephiroth is descending from the ceiling, his hands are bare. However, in the rest of the scene, he has gloves on.
Despite stating that Professor Hojo is a walking mass of complexes, he himself (at least after his downfall into insanity) fits that description. Sephiroth is shown to have a Messiah Complex, a God Complex, and is widely believed to have an Oedipus Complex, as he detests his father Hojo, and, to some extent, worships his "mother" Jenova.

The Masamune is named after Masamune Okazaki, the legendary Japanese blacksmith, considered the greatest in history. It is often compared to the Muramasa, though always the better of the two. According to legend, Masamunes are marks of an internal peaceful and calm warrior, the exact opposite of Muramasas.

Date of his birth: 1977

Dear members of the Silver Elite:
In this update, we present another piece of Sephiroth
trivia—the secrets to his beautiful long hair.
The hair products he uses are of the highest grade,
made and supplied by the Shinra Company.
He seems to use one whole bottle of both shampoo
and conditioner every time he washes his hair.
They are scented with thirteen kinds of perfumes,
including Rose and Vanilla.
Apparently, the scent in the air after
Sephiroth tosses his hair changes daily!
