Anime Biography

In Episode 53, Demios Sword Dragon appeared as Purgatory Knight's Buddy monster during his match with Noboru Kodo in the semi-finals. When he activated his ability to stand, he told Purgatory Knights, Iron Gerd Dragon prepared to be sacrificed for victory's sake, which Iron Gerd took with pride. After the fight Tasuku called him in the middle of an argument with his former Buddy Jack. Demios was ready to attack but was interrupted by Kiri's Great Spell, Ragnarok.

During the final battle of the Gaen Cup he was reminded of his old days at Dragon World when battling Drum's Super Armordragon form and revealed that he used to be a Super Armordragon as well. He enjoyed destroying Drum in battle twice, telling him to learn his place. Demios had to sacrifice himself so Tasuku could use Purgatory Flame that Resides Within the Body.

He was later recalled to the fight when Jackknife Dragon was on the field. Demios immediately noticed Tasuku was desperate to destroy Jack. His first attack failed due to Dragon Barrier, but with his ability he tries to attack Jack again, telling him that Tasuku abandoned him because he lacks the guts to do whatever it takes to win. To his surprise, Jack manages to overpower him with Dragoenergy, and before being defeated he insulted Jack again.
