Kadaj

"I've never known Sephiroth. I just... I sense him there. It's unbearable to think that Mother might want Sephiroth more than..."

- Kadaj (about both Sephiroth and Jenova).

Kadaj is the primary antagonist of the novel Final Fantasy VII Lateral Biography Turks -The Kids Are Alright- and the secondary antagonist of Final Fantasy VII: Advent Children. An embodiment of Sephiroth's will manifested from the Lifestream, his goal is to find Jenova, whom he considers his mother, and bring about a second Jenova Reunion.

The novel Final Fantasy VII Lateral Biography Turks -The Kids Are Alright-, written by scenario writer Kazushige Nojima, sheds some light in the events that happened prior to Final Fantasy VII: Advent Children.

Appearance
Like the other embodiments of Sephiroth's will, Kadaj resembles Sephiroth to a great degree and is described by Vincent Valentine as a "larval" form of Sephiroth. Kadaj wears black leather clothing with gauntlets and a coat, which he keeps zipped up. The image of a single wing is sewn on the back of his coat as an allusion to Sephiroth. He has shoulder-length silver hair that partially covers his face and green cat-like eyes. Kadaj's weapon is the Souba, a katana with two parallel blades that he carries in a sheath on his lower back.

Personality
"So what if I'm a puppet? Once upon a time, you were too!"

- Kadaj to Cloud.

Kadaj embodies Sephiroth's cruelty and hatred. He is devoted to Jenova and dedicated to finding her, but is unaware of Sephiroth's influence over Jenova. As a result, Kadaj is insecure over Jenova "choosing" Sephiroth over him, and though he does not fully understand who Sephiroth is, he tells Rufus Shinra he can sense his presence.

Kadaj is arrogant and mocks Rufus and the Turks, and thinks of Cloud Strife as his "brother" through Jenova, but considers him a traitor to their cause. When driven to anger Kadaj attacks with fury, such as when he attacks Cloud when Cloud reminds Kadaj he is only Sephiroth's pawn. Nomura describes him as "talking quickly, then speaking slowly or breaking into laughter for no apparent reason".

Powers and Abilities
Kadaj is a highly skilled swordsman and battles Cloud competently one-on-one. When Cloud is weakened due to Geostigma, Kadaj can defeat him, and is strong enough to defeat both Reno and Rude alone. Kadaj can summon hordes of Shadow Creepers from the Lifestream, and uses Materia to summon Bahamut SIN. In Advent Children Complete, Kadaj infiltrates Healen Lodge by transforming into a black mist.

Upon walking into the water at the Forgotten Capital it turns dark and the Jenova cells within the children become active when they drink it. This may be a form of Limit Break, as Kadaj glows in a manner similar to other characters in the film when they use their Limit Breaks.

In Turks -The Kids Are Alright-, Kadaj appears before certain individuals under the guise of deceased persons from their past to manipulate them to help him search for Jenova, reminiscent of Jenova's transformation power. He can vanish and reappear in another location, and to become immune to attacks from firearms, likely extensions of his ability to disperse into mist. He can take away people's physical pain as well as re-grant it, as evidenced by his "mending" Evan's shoulder wound and his encounter with Evan in the mountains.

Unlike most antagonists with great physical and magical power in the Compilation of Final Fantasy VII, Kadaj does not have Jenova cells, and not acquire Materia until halfway through the events of Advent Children. His unusual magic abilities are derived from the negative Lifestream that makes up his body, while his great physical strength and combat proficiency come from being a personification of Sephiroth's memories.

Final Fantasy VII Lateral Biography Turks -The Kids Are Alright-
Kadaj was born in a pond of blackened water near Nibelheim. He saves Kyrie from sinking in the pool, and ends up conversing with her at Dr. Drake's office, with the latter seeing him as a friend who died in a fire, due to Kadaj's ability to mimic the appearance of one's dead relatives, a trait he shares with Jenova. Kadaj later disguises himself as Dr. Drake and Fabio, and takes away Evan Townshend's pain from the surgery when his arm was shot.

When confronting him at a cabin on the mountain, he gives him back his ability to feel pain. Kadaj later attempts to manipulate Kyrie into supplying him information on Jenova's remains, but Kyrie shoots at him. Kadaj attacks a Turk helicopter and tricks it into shooting itself down with a missile. He goads Kyrie into going into one of the crevasses and pursues them in the caverns, only to end up diving into the Lifestream and dissolving after Evan kicks the still-living remains of Jenova into it.

Final Fantasy VII: Advent Children
"My reunion, bet you're dying to watch..."

- Kadaj to Cloud right before turning into Sephiroth

Kadaj's trip into the Lifestream, like Sephiroth before him, does not kill him. He revives himself within the North Crater]] as the Turks are collecting Jenova's remains, as well as having two more Remnants of Sephiroth, Loz and Yazoo, come to existence alongside him. They defeat the Turks, before deciding to locate Jenova's head, which the Turks escaped with.

Kadaj appears on the Midgar Wasteland to summon Shadow Creepers to attack Cloud while he is out riding his motorcycle. After speaking to one of the Turks over the phone, he recalls his monsters and sets off to find Rufus Shinra. Arriving shortly after Cloud leaves Rufus, Kadaj reveals that the plague Geostigma is caused by the remnants of Jenova in the Lifestream, and that those infected are part of a plan for a second Jenova Reunion that will recreate Sephiroth. Geostigma alone is not enough and Jenova's remains are needed, and Kadaj believes Rufus knows where they are.

With a group of infected children brought to the Forgotten Capital, Kadaj tells them Geostigma is caused by their bodies rejecting Jenova's influence, and that her presence makes them brethren. Kadaj has the children drink from a pool of dark water, activating the latent "reunion instinct" in their Jenova cells. Cloud battles Kadaj and his brothers, but outnumbered and weakened by his own Geostigma infection, is defeated and saved by Vincent Valentine. Vincent tells Cloud of the true nature of Geostigma, and the impending rebirth of Sephiroth it could mean, although he does not yet reveal Kadaj's connection to Sephiroth.

With the reunion instincts of the children to guide them, the Remnants look for Jenova's remains in Edge. Loz and Yazoo battle the Turks and Kadaj summons Bahamut SIN to attack the city. During the attack, Kadaj confronts Rufus and confirms that Sephiroth is about to be reborn. After Cloud and his friends defeat Bahamut SIN, Rufus reveals Jenova's remains in a box concealed under his cloak.

Casting the box off the building where they are standing, Kadaj leaps after it catching it mid-air. The ensuing chase between the Remnants and Cloud along the highways into Midgar apparently kills Yazoo and Loz. Kadaj gains the lead and stops at the Sector 5 Church to inspect Jenova and is horrified at what is left of her and cries. Cloud bursts in, and an enraged Kadaj attacks him. Aerith calls a geyser of healing water to erupt from the flowerbed, wounding Kadaj and causing him to flee. The water cures Cloud of his Geostigma.

Cloud confronts Kadaj outside the ruins of Shinra Headquarters. Kadaj is unaware of what to do with Jenova's remains now that he has them, and when Cloud points this out, he attacks. Back to his full strength, the battle ends with Cloud as the victor and Kadaj hanging from the edge of a tower. Kadaj leaps into the air and absorbs Jenova's remains into his body, leading to the recreation of Sephiroth moments later.

After Sephiroth is defeated, a mortally wounded Kadaj is reformed from his dissolving remains, and attempts a halfhearted attack on Cloud, but instead collapses into his arms. Weakly calling him "brother", Cloud holds him while Aerith speaks to Kadaj from the Lifestream. Believing her to be Jenova, Kadaj calls her "mother" and happily dissolves with her guidance.
