The Pokémon anime has featured numerous enigmatic artifacts from ancient civilizations, but one of the most intriguing was a mask and staff that granted the ability to fully control any Pokémon, even without capturing them. This meant that anyone, including Team Rocket's Jessie, could become a trainer at the level of a Pokémon Master.
In the Johto era episode titled "Control Freak!", Ash, Brock, and Misty pursue Brock's Golbat until they stumble upon a woman unconscious at an archeological excavation site. Her sonar device is damaged, so Brock offers to aid in its repair. The woman informs them about her mission to locate the aforementioned mask and scepter, once possessed by a revered queen. Predictably, when Team Rocket learns of this artifact, it becomes the focal point of the episode. However, what is truly surprising is that Jessie manages to obtain the artifact and successfully harness its power.
The Mask And Scepter Give Anyone Complete Control of Pokémon - In One Limited Area
Jessie tests the artifacts on James' Victreebel, summoning it from its Poké Ball and commanding it to attack James. Without delay, she then directs it towards Pikachu, taking control of its mind and compelling it to go with them. Every Pokémon called upon by Ash and his companions succumbs to Jessie's control, and to make matters worse, she now has Pikachu as her protector. Team Rocket seems to have the upper hand until Jessie and Pikachu accidentally cross a marking on the ground, which happens to be the boundary where the artifacts lose their effectiveness. In reality, it proves impossible for Team Rocket to utilize these items for Pokémon theft, as they only work within the confines of the dig site.
The possession of such an ancient artifact by Team Rocket poses an immense threat, so it turns out to be fortunate that its reach is limited. Its existence offers a fascinating glimpse into a time before Poké Balls, showcasing humanity's longstanding desire to wield the immense powers possessed by Pokémon. The Pokémon animated series often incorporates ancient ruins like these in its episodes, but this particular instance is especially unique, as there is no trace of a Poké Ball involved. It is also remarkable that the device can override even the technological controls within Poké Balls and influence Pokémon kept inside them.
Team Rocket ends up losing the artifacts and being blasted off. While these items might have been used to protect the queen's city and her followers, they hold little value now that the city no longer exists. Ash, who aspires to become a Pokémon Master in the right way, was not enticed by such a shortcut. Nonetheless, it is concerning to have such a potentially hazardous item unaccounted for in the Pokémon world, so hopefully its existence has remained undisclosed.
