Pokemon Legends Arceus notably featured multiple expansive collection quests which challenged players to fully explore the Hisui region in order to obtain certain Pokemon. While Pokemon Legends Z-A will almost certainly use collecting Zygarde Cells as the replacement for Arceus' Spiritomb Wisps, what Pokemon will replace the Unown is less clear. While the alphabetical theming of Pokemon Legends Z-A and its generation could mean that the Unown themselves will see a return appearance, there are several Kalos Pokemon that could take up their role.
