The two Pokémon growl at each other before charging, with Walrein getting on top of Camerupt and biting down on him. Archie reveals that Walrein's fangs have the ability to release a cold gas that can freeze any opponent. Unconcerned Maxie mentions that Camerupt has Magma Armor as his ability, allowing him to ignore any damage Walrein could have dealt. Taking the opportunity to counter attack Camerupt uses a powerful Eruption, blasting Walrein off of him. Despite the force of the Eruption, Archie reveals that Walrein's Thick Fat ability kept it from being badly damaged. Realizing that neither of them are going to win the Trainers recall their Pokémon and decide to talk through their issues.
In The Beginning of the End with Kyogre & Groudon X, Camerupt is used alongside Archie's Walrein to battle against Ruby and Sapphire. He starts the battle by attacking Ruby's Swampert, Mumu. Mumu easily throws him out of the way to allow the rest of his team to attack Maxie and Archie, but the power of the Red Orb and Blue Orb blast them away. Realizing that Archie and Maxie aren't battling in sync the two Pokédex holders decide to attack by complimenting their strengths and weaknesses.

Red and Green counter by having their Saur and Blasty Mega Evolve as well. Eventually, Saur and Blasty succeed in defeating Camerupt and Sharpedo, but the battle was interrupted by the arrival of Groudon and Kyogre. Maxie and Archie use the orbs to turn Groudon and Kyogre into their Primal forms. With its new power, Groudon proceeded to easily defeat Red and Green by creating a sink hole to bury them under.
