Cry Cute: "Milord Poseidon... now you're back to being Young Julian Solo..."
Dark Chick: While she does have the fighting abilities, she's more of a messenger than a frontline fighter.
Happily Ever After: In the end of the Poseidon Arc in the manga, Thetis changed back into a fish. Jullian/Poseidon comes back and finds her dead fish body and holds it gently in his hands. In the anime, it was happier where Thetis changes into a mermaid and you can see her leaping in and out of the water with the good guys staring at the sunset.
Defiant to the End : Prefers to go down fighting towards Shun despite being bound in chains, trying to block Shun's direct attack (via Libra Cloth's weapons) on the pillar he protected. Shun is very impressed at his Undying Loyalty to Poseidon and expresses sadness at his passing.
Senseless Sacrifice: Tries to keep Shun from destroying his pillar by shielding his body. Unfortunately, he never had a chance due to him being bounded up and the pillar itself being too big to protect all of it.
Critical Research Failure: In-universe case. Had he bothered to scan Ikki's mind throughly, he could've found about Esmeralda earlier, therefor using her form to kill him. He could have won the war for Poseidon's side right there!
Knight Templar: He admires the Kraken because it would sink ships with sinful people on them. Hyoga questions this, as it would entail killing innocent people which just happened to be on board as well. Isaac still calls it the best way of making justice.
Kick the Dog: Or better said, the puppy, as he kicks poor little Kiki when he brings Hyoga the Libra Cloth. That pisses Hyoga off enough to return to the fight.
BADASS: After his Heel-Face Turn and becoming the Gemini Saint, in the Hades Arc he singlehandedly kills more Specters than half the Gold Saints combined. Only Shaka and Dohko can compare in kill counts. He even has the honor of being the only Gold Saint to kill a Judge in the classic series.
Genius Bruiser: He is responsible for most of the conflicts within the classic series. He manipulated Poseidon into doing starting his next holy war against Athena earlier than scheduled, awakened the evil in Saga's heart and drove him into insanity, and ALMOST SUCCEEDED in gaining world domination until he made the fatal error of underestimating the main Bronzies.
