Season 5: Master Quest
Mary, along with Ken, are the sole members of Pokémon Mystery Club (PMC). They went to investigate about unusual Pokémon activity in the area and found a bunch of Clefairy. However, the heroes stopped them, while Team Rocket was jealous of their technology. Team Rocket also wanted the Clefairy, so made a tempoary alliance with the PMC, but both groups blasted off by Pikachu's attack.
Season 7: Advanced Challenge
Mary and Ken returned to capture a Lunatone, who crashed and used the psychic powers to influence certain people. They used a lot of technology, but like the previous time, they failed and blasted off.
