The Time Gears hold great significance in a world filled with Pokémon and reliant on communication. These legendary treasures are responsible for regulating the flow of time in their designated regions, and their absence would cause irreparable damage. Even wicked Pokémon shun the idea of taking them, fearing dire consequences. However, time disturbances have spread, leading to the emergence of aggressive Pokémon and mysterious Mystery Dungeons, prompting explorers to tackle this issue. Surprisingly, the absence of the Time Gears is not the cause of these anomalies. Instead, they stem from the deterioration of the Temporal Tower and Dialga's corruption into Dark Dialga. In an attempt to prevent the Tower's inevitable collapse, infamous thief Juptile aims to steal the Time Gears. To evade an eternal stasis, Hikozaru, Pochama, and Juptile must journey to the Phantom Land where the Tower resides. Failure is not an option, as time freezes without the Tower.
