Cecil Harvey/Dissidia (PSP)

Cecil is one of the Warriors of Cosmos in Dissidia Final Fantasy.

Destiny Odyssey IV
Throughout Cecil's story, Golbez appears to give his younger brother what seems to be advice on seeking the Crystals. Although Golbez is the enemy, Cecil still wonders if he can be trusted as his brother. He eventually leaves his allies and meets with Golbez, when they are interrupted by Exdeath. Believing Golbez a traitor, Exdeath attacks him, but Cecil defends his brother and engages Exdeath. Although he prevails, Golbez tells Cecil he lent him his power during the battle, and finding the Crystals requires him to use his own strength. Cecil asks Golbez to come with him, but Golbez refuses as he has been stained by darkness and cannot be redeemed. Cecil eventually meets Cosmos, who confirms that a strong will and strength is the key to finding the Crystals; Golbez was telling Cecil the truth. Cecil confronts Golbez again, and Golbez demands Cecil fight him. Cecil awakens his light powers and uses both light and darkness to defeat Golbez. Golbez hands over his Crystal, and although Cecil claims they made it shine together, Golbez replies that Cecil did it alone, which was the point of his meetings with him.
