|Guardian Bakugan|| Raptorix|
Captain Elright, later promoted to Commander, is the leader of the Neathian Castle Knights. He is a Haos battler and his Guardian Bakugan is Haos Raptorix. He inducts the Brawlers and Princess Fabia into the Castle Knights.
In The Secret Package, he was leading troops to hold back the Gundalian forces, but when the first shield was destroyed he sent Linus to Earth to find Princess Fabia. Elright was then captured and interrogated by the Gundalians to reveal his location.
In The Sacred Orb, he is able to escape from the Gundalians and returned to Neathia to battle alongside the Battle Brawlers. Also, his Guardian Bakugan is revealed to be a Haos Raptorix, meaning that he is a Haos brawler. In the end, he appoints the Battle Brawlers, as well as Fabia, to the Castle Knights.
He reappears in Decoy Unit, showing the Brawlers who the Twelve Orders are and the current situation for Neathia without the second shield. He and Marucho devise a decoy plan to distract Airzel, Kazarina, and Stoica, who are closing in, while Dan, Shun, and Fabia sneak behind and reactivate the second shield. He is shown battling alongside the other Castle Knights while Marucho and Jake battle Airzel and Mason.
Elright seems to be very brave. He also makes the fact that the Neathians are good at hand-to-hand combat closer to true.
He appears to have been promoted from Captain to Commander in episode 35 because Queen Serena and other Castle Knights were calling him Commander Elright
Since more Chaos Bakugan arrived in Battle Lines he fought them along the Gundalians with Aranaut.
- Elright and Queen Serena are the only main Neathians who have not been shown in a human form, not counting the deceased Jin.
- Aranaut is his new Guardian Bakugan, since Fabia can't battle anymore.
