In Losing Its Lustrous! and Double Team Turnover!, Garchomp was used to battle Team Galactic's Pokémon. Paul forfeited after this, giving Cynthia the win. When it tried to follow up with Frenzy Plant, however, Garchomp pried apart the roots and knocked Torterra out with a Brick Break to the head.
Torterra managed to inflict damage on Garchomp, immobilized from Giga Impact, with Giga Drain. She easily overpowered his Murkrow, with Giga Impact besting Sky Attack, before fighting against his powerful starter Pokémon, Torterra. Once again, her incredible resistance was showcased, as Cynthia allowed her to absorb Chimchar's Fire Spin and Weavile's Blizzard, before knocking out the former with Dig and the latter with Dragon Rush.
In the same episode, she battled against Paul when Cynthia accepted Paul's challenge for a Full Battle. Even though Bronzong was shown to be a powerful Pokémon in the battle against Dawn's Buizel in An Elite Meet and Greet!, the Bronze Bell Pokémon's Flash Cannon barely did any damage to Garchomp, who knocked it out with Giga Impact. Garchomp debuted in Top-Down Training!, where she was seen battling Lucian's Bronzong.
