In "Guilty Gear XX Accent Core Plus" (2008), Sol had two endings. In one, I-No threw him back in time to fight his past self, Order-Sol. After both are weakened from the battle, I-No reappeared to murder Order-Sol, which, in turn, caused Sol's present form to cease existing. In his other ending, the same set of events played out, but Sol's present form, strangely, is unaffected by his past self's death. After escaping the time rift, Ky confronted and engaged him in battle. After the fight, Sol and Ky finally settled their differences and went their separate ways, with Ky asking Sol to promise that they will meet again. Though it was referenced in both Sol and Ky's endings, only Sol's told the events directly after the battle, which implied that Sol was the victor.
