Marlon's Jellicent was the first Pokémon he used in the gym battle against Cameron. Marlon's Jellicent was matched up against Cameron's Ferrothorn which was odd considering it was a water based gym arena and there was only a small platform for it to stand. Cameron thought he did well in the battle and was going to have an easy victory in the match by quickly defeating Marlon's Jellicent but Marlon's tactic was revealed when Marlon's Jellicent Ability Cursed Body disabled Cameron's Ferrothorn Thunderbolt.
