Dying as Yourself / Died in Your Arms Tonight: After being struck to death by Hyoga, he regains control of himself and, as his last act, destroys the ice the pyramid built for Arles by Gigas and collapses into the arms of his pupil. Before giving up the ghost, he asks for forgiveness for what he had done to Hyoga.
Canon Foreigner: Is the master of Hyoga in the anime and the substitute to Camus in all the flashbacks of the training.
Good Is Not Dumb: Was also aware that something wrong went on in the Sanctuary, so he tried to talk to the Pope himself. It backfired. Horribly.
Eye Scream: When Black Swan takes out his own eye and sends it to Ikki to inform him of his technique. This is only in the manga.
Noble Demon: Black Dragon. At the end of their fight, instead of attacking Shiryu, he hit Shiryu's point to stop his bleeding and he says that he wanted to believe in the friendship which Shiryu had spoken during combat, and soon dies after the hit that gave Shiryu before.
Obviously Evil: Supposedly former Saints (or trainees) who were stripped from their title and Cloth and banned from the Sanctuary for using their strength for personal gain, turning to a life of crime and violence.
Poison Is Evil: What makes Black Pegasus different than Seiya. The difference is that shortly after hitting its target (through their Cloth), there are dark spots all over the body of the ending completely covering it, causing the sensation of burning himself from within. Once the body of the enemy is completely black, they die.
The Psycho Rangers: To the Bronze Saints. They managed to produce copies of Athena's Cloths, but as they lacked the knowledge and the permission of the Goddess, those Black Cloths are somewhat inferior to the original Cloths, being easily shattered by the blows of a Bronze Saint.
Chuck Cunningham Syndrome: They kind of just... disappear when Seiya and the gang leave for Sanctuary. It's not even between episodes or anything - they're there in one scene, then gone in the next with no mention.
Blow You Away: In the his attacck, Heracles Fierce Onslaught Fist, Docrates crosses, then flexes his arms, concentrating his Cosmo in his fists and causing the winds around of him to change due to the pressure. Next, he attacks with both fists, projecting two powerful blasts which affect a large area.
The Brute: A cold and aggressive character, full of mischief. He has extremely high physical strength derived from its huge size and musculature.
Filler Villain: His appearance in the anime creates a different storyline than the manga, with the emergence of several unique characters.
You can tell since he's the only villain in the entire series who decides to bail when the cops show up!
Muscles Are Meaningless: Adverted, his great strength and size actually forced the Bronze Saints to use teamwork in order to defeat him.
However he fought the Bronze Saints, each time when they were not at full strength. Hell the only reason why they flee him in the first place is because of the very tough battle they had with Ikki, and it takes them a while to return to full power in series.
Not Drawn to Scale: At the end of one episode, he was holding Saori around her waist with ONE HAND and Tatsumi in the other. (It seems Shingo Araki likes these a lot, and that It Runs in the Family since Cassios did the same to Seiya)
Wolverine Claws: Blink and you'll miss, but they come out when he's about to perform a finishing move on Seiya in episode 17.
