Cameron is a Pokémon Trainer that Ash and co. met at Lacunosa Town after the Pokémon World Tournament Junior Cup in BW095. He is another one of Ashs's rivals in Unova.
Cameron first appeared in BW095. He appeared alongside his main partner Riolu and was meant to compete in World Tournament Junior Cup, but much to his dissapointment , he was too late and the Cup was over already, so he left off. Later in the same episode he shows up after Ash and his friends say their ferewell's to Dawn, there he officialy announced that he is going to enter the Unova League, he originally mistakenly thought that trainers only needed seven badges to enter the League but found that he eigth badges to enter. Jervis tells him there is a gym near Town located in Humilau City. He decides to head there, Ash and friends offer to go with him and gladly accepts.
In the next episode, as Cameron along with Ash and his friends were traveling Humilau City, Cameron, Ash, along with Riolu, Pikachu, and Meloetta get lost in the forest. Meanwhile, Iris and Cilan find out about and head to humilau city anyway, hoping they will find them there. Cameron and Ash tried many ways to find out where the city was, but failed, the two gave it a rest and decided to camp out on a cave along with the other pokemon that night. Finally the next day Cameron and Ash find Humilau city, there they see a big Wailord coming right at them, the Wailord was owned by none other than Marlon the Humilau Gym Leader. Marlon the offers them a ride and takes them to Humilau City.
After arriving to the Gym, Cameron challanges Marlon to a battle, Marlon accepts. At first, Cameron was going to use his Riolu to battle, but because he left it on the other side he couldn't use it, he had no choice but to use his other pokemon. The match then got started, the first pokemon Marlon used was his Jellicent, Cameron then sents out his Ferrothorn, Ferrothorn first uses Pin Missile but jellicent was easily able to dodge it, Jellicent then used Shadow Ball, Cameron then commanded his Ferrothorn to use Thunderbolt, knocking Jellicent out. Marlon then sent out Mantine, Cameron ordered his Ferrothorn to use thunderbolt but he found before jellicent was knocked it used it's ability cursed body to disable Ferrothorn's Thunderbolt, Marlon ordered his Mantine to use Bullet Seed on Ferrothorn easily defeating it. Cameron then used his Sammurott to battle Mantine, Samurott proves to be really strong using it's fast speed underwater to easily dodge all of Mantine's attacks. Cameron then orders Samurott to use aqua jet finnally defeating Marlon and getting his 8th gym badge to enter the Unova League. Afterwards, Cameron and Ash depart ways and promise to meet in the Unova League.
Cameron has a habit of making a lot of errors like he thought trainers only needed seven badges to enter the Unova League, and thought that it was going to take in Ecruteak City in the Johto region or sometimes setting up tents like he did in the Unova League to be early but was actually late. He also has the habit to accidently hit himself on the head by stretching his bandage usually while battling or when frustrated. Though he does have very impressing battling skills as shown when he battled Marlon and Bianca.
