Celebi flew in. "Bi bi bi Celebi." Celebi said. Celebi dropped a shrunk Master Ball into Liam's hand.
"Where did you get this?" Liam asked. Celebi to save time sent a telepathic message though Liam's mind. Somewhere in the future a trainer attempted to use a Master Ball to catch a different Celebi. They got surprised by an Ursaring's roar and dropped the ball. That Celebi swooped down and grabbed the ball, which was still in its shrunk state and ran off though time.
"So, you brought me a Master Ball from the future?" Liam inquired. The Celebi implied that the ball was form one year in the future. Zygarde said that he had wanted to challenge one of the two, to test their mettle once more.
