In All for the Love of Meloetta!, Garchomp battled Iris's Axew. Axew's Scratch and Dragon Rage successfully hit Garchomp but seemed to do no damage. Garchomp then used her Dragon Rush and Draco Meteor attacks to cause a lot of damage to Axew. At the last second when it seemed like Axew was down, he got back up and ended up knocking Garchomp down with his newly learned Giga Impact and shocking everybody. Garchomp quickly recovered and was about to finish Axew off with a Brick Break but was called off by Cynthia at the last second.
In Jostling for the Junior Cup!, Garchomp battled Caitlin's Gothitelle in an exhibition match for the Pokémon World Tournament Junior Cup. After being initially confused by Flatter, Garchomp was repeatedly slammed on the battlefield and finally lifted high into the air by Gothitelle's Psychic. Overcoming the confusion, Garchomp cleverly used the top of the stadium to launch herself forward to deliver a successful Dragon Rush. After Garchomp's Draco Meteor was stopped by Gothitelle's Thunderbolt and both their Brick Break attacks clashed, the battle's inexplicitly short 10 minute time limit ran out, and the match was named a tie.
Cynthia was shown to have a strong bond with Garchomp, as Garchomp was shown to have been used more often than her other Pokémon. Similar to other Pokémon belonging to Champions, Garchomp was shown to withstand attacks coming from other Pokémon, which was shown during the battle with Paul as she was easily able to defeat Paul's team without a scratch. Garchomp was also helpful when Ash and his friends dealt with Team Galactic and Team Rocket on two separate occasions.
Garchomp is Cynthia's main battling Pokémon in Pokémon Adventures. Garchomp is well trained enough that she can battle even without her Trainer giving her commands. Garchomp first appeared with her Trainer in Ring Around the Roserade II, where she held Cynthia's coat while Cynthia helped train Platinum.
In Suffering Psyduck, Garchomp was used to take Diamond, Pearl and Platinum to Route 210 so that Cynthia can heal the Psyduck barricade there. Later, Cynthia lent Garchomp to her Grandmother so that she, Diamond, Pearl, and Platinum could make it to Celestic Town safely. Upon arriving, Garchomp gets into a fight with the leader of Team Galactic, Cyrus. She attempts to prevent Cyrus from entering the Celestic Ruins, but inadvertently assists him in getting inside after her accuracy is lowered, causing her attacks to miss and make a bigger opening.
In Shunning Spiritomb, Garchomp was used as Cynthia's third and final Pokémon against Cyrus at the Galactic HQ. Still angry from their previous battle, Garchomp attacks Cyrus's Gyarados ferociously. Seeing how angry she was, Cynthia has Garchomp use her strongest move, Draco Meteor, despite the fact that they haven't fully mastered the move yet. The attack, while powerful, was made weaker by Garchomp's fury, preventing her from being strong enough to defeat Cyrus, and left Garchomp to pursue the escaping opponent. With Cyrus gone, Garchomp was used to take Diamond, Pearl, and Platinum to the Spear Pillar for the final battle against Cyrus.
In A New Battle Begins!, Garchomp was used to battle Mitsumi's Infernape. Both sides charged at each other with Giga Impact and Overheat, respectively. They were both recalled for Lucario and Electivire. Garchomp and Infernape were sent out again later on. Infernape attacked with Focus Blast in which Garchomp dodged. The Focus Blast headed straight for Hareta and Koya, in which Koya protected himself with Metagross. Garchomp won the battle by default when Mitsumi decided to resign seeing that it was more fun for her to watch the tournament instead of fighting in it.
