During the P-1 Grand Prix in Persona 4 Arena, the Malevolent Entity realized that if he had succeeded in taking the Shadow Selves of the Investigation Team or the Shadow Operatives their ego would have overpowered him. As part of his plan in Ultimax, he set up a new tournament where the battles between the fake Shadow Selves and the Persona Users would lead to fragments being carved off the Personas who battle in the red fog, which also leaves the winner of the battle fatigued. By using the Persona Fragments that gathered at the top of the tower, he would be able to suppress the shadow's ego in order to gain control of the body that would born when the shadows merge to summon a god.
