Character Profile: Kadaj

Kadaj is one of three beings created by Sephiroth as manifestions of "his will". He and his "brothers", driven by Sephiroth's will and their own personal obession, sought out their "Mother": Jenova's head. Kadaj represents the bulk of Sephiroth's personality.

Having Yazoo abduct the children with Geostigma, a product of Jenova's influence in the lifestream, he intended them to serve as bloodhounds to find Jenova's head. He even used the Bahamut materia to hold the other at bay until he learned Rufus possessed Jenova all along.

Through absorbing Jenova, Kadaj became Sephiroth, whose intent was to use the Geostigma to choke the lifestream and use the planet to start over again on another planet, much like Jenova did in the past. This did not happen because Cloud defeated Sephiroth, mortally wounding Kadaj in the process. Hearing Aerith's voice and assuming her to be his "mother", Kadaj was freed of Sephiroth's influence and faded into the Lifestream.

Kadaj's weapon is the Souba.

Technically, Kadaj, Yazoo, and Loz can only be two years old, because they were created after the battle, two years before the start of the movie after Sephiroth's demise. However, someone points out that if Advent Children happened 7 years after Final Fantasy VII and Zack's death happened AT LEAST a before that then it is impossible for Kadaj to only be 2 years old chronologically because Kadaj, Yazoo and Loz all made an appearance in 2nd Class Solider uniforms (shot was of nose down) saying "we have to find big brother"( or something to that effect) at the very very end of Final Fantasy VII: Crisis Core for the PSP. In addition to that, they haven't aged.
