The Last Battle I (Japanese: ) is the 167nd round of the Gold, Silver & Crystal chapter in the Pokémon Special manga.
This chapter starts out with the Mask of Ice stating that he requires Kurt to create a Poké Ball to control time. He also contemplates Krystal's use of Future Sight, iterating that she was able to understand the concept of time well, even if for just a few seconds. After praising her, he recalls the goals of the past villainous groups, Team Rocket and the Elite Four, and reveals that his goal is to have complete control of time. As Kurt pretends to not know how the control of time is possible, the Mask of Ice grabs his granddaughter and holds her in a threatening matter as he surreptitiously steals Kurt's manual, which has data on all types of special Poké Balls.
After he finds the information on the Ball that can surpass time, Kurt mocks him, saying that the manual is worthless without the ingredients for the Poké Ball. The Mask then states the he already know what the ingredients are, and, as he refers to the wings of Ho-oh and Lugia, his Delibird Thief the Rainbow Wing and the Silver Wing from the legendary Pokémon and gives them to his trainer. While he states that he will finally gain control of time, Gold grows angry over the prospect that Pokémon were being used just as ingredients and materials to the Mask. He then demands what Pokémon are to the Mask of Ice and gets the response that they are mere weapons.
The Mask then loses his patience with the conversation and attempts to attack both Gold and Kris, but, as Gold pushes her out of the way, Kris is unharmed while Gold takes the whole of the hit. Kris then begs the Mask to stop but is shrugged off as he flies away. As Gold gets up from the attack he had absorbed, he privately vows to not give up until the Mask of Ice is defeated.
The chapter closes with the Mask of Ice flying on his Delibird towards Ilex Forest, stating that he has finally obtained a "second chance at time."
