Changes

Yako is extremely determined to revive Pegasus, not letting anything stand in his way; let be it be Yugi and his friends or [[Seto Kaiba]]. His mentality seemed to be slowly warped by the presence of the [[Devil Gods]], twisting him more and more as he had been exposed to them over time. He claims that [[Pegasus]] was his master and everything to him, and losing him was the worst tragedy that could befall him. He also held great enmity for his twin, Gekko. Gekko was often praised by Pegasus as a "perfect" duelist, and Yako often felt that he was dueling in the shadow of his twin. He failed to realize that Gekko was "perfect" in the fact that he would experience no growth as a duelist, and was as strong as he'd ever be. Yako's feelings for Gekko eventually caused him to use his brother as a pawn in his battle against Yugi. After the destruction of [[The Wicked Avatar]], Yako's personality returned to his kind, calm demeanor he held before being exposed to the gods.
