Kadaj is the dumbest of the three bad guys in Advent Children. He thinks he's in charge, but he's just a little kid with a big ego who wants to turn into Sephiroth and beat up Cloud.
Kadaj: 'I'm gonna be Sephiroth and destroy Cloud!'
Kadaj: 'I'm the leader! I'm the best!'
Kadaj: 'I'm gonna take over the world... probably.'
