The Akatsuki Leader was first recognized when he single-handedly stopped a growing quarrel between Deidara and Sasori with just a verbal command. It is unknown whether the Akatsuki Leader has a partner, but it is likely that the only unnamed member of the Akatsuki is his partner. The Leader is among the most devious characters in the story: his entire face has never been seen, even in the manga.

Appearance
The Leader wears the traditional Akatsuki cloak of black and red clouds. His hair appears to by spiky in a fashion similar to Naruto, but this is not completely proven either way.

Speculations

 * Many speculate that the Akatsuki Leader is the Fourth Hokage, but it is objected to by others since the Fourth Hokage was dead for a long time.
 * It is highly probable that the Leader is the most lethal of the Akatsuki, but he never was seen in combat.
