Julian Solo

•Poseidon no Hoko: This is a lethal technique in which Poseidon creates a great whirlwind with his cosmos that envelops him and throws his enemy far away. He then raises his trident accompanied by enormous columns of cosmos, then throws his weapon with enormous force, which gains tremendous momentum during its trajectory towards his enemy until it impacts. Finally, upon hitting the enemy, a huge explosion is generated that engulfs the enemy. •Sea God Defense Wall: is a technique that consists of creating a wall made of Cosmos that reflects the attacks of opponents. •Tempest Noah: is a technique of Poseidon, in which he spins his trident above him, and then throws devastating blasts of his divine cosmos at the opponent. •Sea God Wave: is a technique that consists of launching powerful discharges of cosmic energy either through the hands or with the Trident of Poseidon. •Ground Rage: is a Poseidon technique, the god uses his Trident to summon a lightning bolt that falls violently on the ground at a certain distance from the god and his opponent. •Geyser: It is a Poseidon technique, the god uses his Trident to hit the ground causing a large amount of water to emerge from under his opponent, which hits him repeatedly. •Invisible Trident: It is a Poseidon technique, the god launches himself along with his Trident, which is surrounded by his cosmos against his opponent, impacting the latter.

•Poseidon's Trident: The Trident of Poseidon is a divine weapon owned exclusively and symbol of the Marine army of the Emperor of the Seas, Poseidon, one of the three main gods of Olympus. The handle is golden, and the three-pronged part is silver with golden ornaments. In the manga, it is worn with a long lilac or light blue ribbon wrapped around the top. The trident is the symbol of the return of the Emperor of the Sea, because in both cases in which this deity is presented alone, he has a rebirth, as when Kanon accidentally awakened Poseidon, having previously been presented with the Trident in the prison of the Sanctuary; also when Julian Solo assumed his role as king of the seas, it was as a consequence of finding the Trident.

However, that's all he can do at the moment, given the situation he finds himself in. After his brief possession by Poseidon, Julian returns to normal, so he tells Sorrento that they must continue their journey, as children around the world are waiting to hear the sound of his flute. Sorrento follows Julian as he analyzes the situation the Saints are in. Although they were once enemies, he hopes they will achieve victory and prevent the world from being covered in eternal darkness.

A few days later, Julian was standing on a beach gazing out to sea when he suddenly heard a beautiful flute playing. When he turned around, he met a young man who introduced himself as Sorrento. He told Julian that he had heard that Julian was on a trip to visit children orphaned by the floods, so he offered to accompany him as his helper. Julian accepted, as Sorrento's music would surely please the children. As they were about to leave, Julian saw the corpse of a beautiful fish on the beach (it was Thetis, who had lost her life saving Julian). Upon seeing it, Sorrento explained that the fish seemed to have been dead for several days and that it might have died after crashing against a rock. Julian felt nostalgic upon seeing the fish and decided to release it back into the sea, shedding a tear, as he wanted the fish to rest in the sea that had been its home. Finally, the two set off on their altruistic journey. Just as the battle between Athena and Hades moves to Elysion and the Greatest Eclipse caused by Hades was about to culminate. Julian, accompanied by Sorrento, was on his journey around the world to help orphaned children due to the floods, so both stop for a moment at Cape Sounion to contemplate the eclipse. At that moment, the spirit of Poseidon (who was sealed in Athena's Vessel) briefly takes control of Julian's body again. Seeing him, Sorrento realizes that the person in front of him was Poseidon and kneels before him, the god explains the situation in which the world is and how this eclipse endangers the existence of living beings, so he has decided to support Athena's Saints, helping the Gold Cloths to cross the Hyperdimension.

Because Poseidon's spirit had not yet fully awakened, Julian's feelings and memories are still present in him, which makes him, when he meets Athena for the first time, react with familiarity towards her, reiterating his feelings and his marriage proposal, to rule the new world by her side and thus avoid a fight. Faced with the young woman's refusal and her intention to fight to save humanity, a new battle begins between Poseidon and Athena. Later, when Seiya and the others are fighting Poseidon, Seiya uses the Sagittarius arrow, with the help of the cosmos of his friends, manages to impact and wound Poseidon in the head. This impact causes Julian's soul to awaken for a few seconds, so the young man wonders where he is and what he was doing, since the last thing he remembers is that he was celebrating his birthday, when suddenly a strange woman appeared in front of him and that an armor was placed on him, after that he does not remember anything. After this, Poseidon's soul awakens, completely suppressing Julian's personality for the remainder of the fight. After the battle against Poseidon, in which Saori achieved victory by using the Vessel of Athena to extract Poseidon's soul from Julian's body and seal it again, Athena and her Saints had to abandon the Underwater Temple, as it began to flood due to the destruction of the pillars that held up the oceans. However, in the midst of the commotion, Saori and the rest left Julian behind, who was unconscious. Therefore, Thetis had to carry him to the seashore to safety. At the end, we can see Thetis, in her mermaid form, walking away from Julian and swimming until she is lost in the sea.

After Julian is rejected by Saori, he notices something shining in the distance in the ancient ruins of a Temple of Poseidon, located high above Cape Sounion, and is drawn there. Upon arriving, Julian finds a glowing Trident and before him appears a beautiful woman who introduces herself as Thetis of Mermaid, a servant in Poseidon's army who will now serve him, as she is the reincarnation of the ruler of the seas, the god Poseidon. At this revelation, Julian is completely shocked and, before he can react, Thetis jumps with him into the sea, crossing it until they reach the seabed. In the Underwater Temple, Julian is amazed to see how the sea water is above him as if it were the sky and that he can move as if he were on the surface. Thetis explains that if someone penetrates to the bottom of the seas they can reach the realm of the god of the seas, and points him in a direction, which when Julian looks he realizes that there is a huge Temple, which is described by Thetis as the Temple of Poseidon. Shortly after, Julian puts on the Scale of Poseidon, falling unconscious from that moment on, so the spirit of Poseidon begins to take over him, then begins his plan to take over the world and punish corrupt humanity, for this he causes floods throughout the planet and orders the kidnapping of the reincarnation of Athena, since she and her Saints have always stood in the way of Poseidon's wishes.

Julian is the last descendant of the prosperous Solo family, who made their fortune through maritime trade. Due to Poseidon's connection with his family since mythological times, the god chose him as the host of his soul. When Kanon released Poseidon's spirit from Athena's Vessel, his soul resided in the body of little Julian, only 3 years old, waiting for the moment when the war would begin. At some point in his childhood, Julian was walking along the shore when he found a fish tangled in some hooks and threw it back into the sea. He didn't know that years later, that fish would become his faithful warrior, Thetis the Mermaid. It is unknown when, but Julian's parents died before he turned 16, leaving him as the sole heir to the family fortune, having to take over all the family businesses. Saori attends Julian's 16th birthday party because her grandfather was a friend of Julian's father. Saori was explaining to Tatsumi the importance of Julian as the new leader of the Solo family, when Julian overhears her and thanks her for her compliments, so he suggests going somewhere more private. Julian tells Saori about his ambitions to expand globally through his family's maritime business, because whoever controls the seas controls the world. Julian asks Saori to share that dream with him and proposes marriage, saying that he felt something special when he saw her, as if it weren't the first time they had met in the world and feels like he has met her again and again since the mythological era. Saori appreciates Julian's proposal, but ends up rejecting it and leaving.

As a child, Julian proves to be a noble boy who loves the sea, which he is in contact with and with which he (tentatively) grew up. It is clear that he loves both the sea and each of its creatures, as evidenced by the fact that he admired the sea and helped fish that ended up stranded on the beach return to the water. When Julian grew up, he became heir to an enormous fortune, formed by his family's maritime businesses, so Julian remained in contact with the sea, loving it and now seeing it from a different perspective (he didn't stop loving and admiring it, but his appreciation for it did "mature" by seeing it as a means of action in business). Although he has been seen as a kind-hearted young man, he has also shown a capricious side, a trait that can be seen after Saori rejects his marriage proposal, as he cannot accept that a woman would reject him and even goes so far as to claim that he would make her his, given that she always gets everything she wants. Julian is presented as a kind and well-mannered man, but once the soul of the god Poseidon manifests in his body, he takes on the god's characteristic personality: angry, but with great firmness and marked ideals. However, Poseidon loves the earth (not so much humans), and that is the main reason why he feels obliged to do something about the current situation. After being freed from Poseidon's spirit after Athena managed to defeat the god, Julian, despite not remembering anything of what happened, seems to feel inwardly sickened by the god's actions while possessing him. He donates his fortune to help flood victims and embarks on a journey to help children orphaned by the floods. This demonstrates Julian's nobler and more altruistic side.

Julian has a reputation for being a handsome young man, so much so that even Saori, who had never met him in person, mentions that she had heard he was very handsome and intelligent. He has a very elegant bearing and a face with fine features, as well as long blue hair, which give him a very attractive appearance. He mostly wears a tuxedo with a white jacket and black or white pants, but when he arrived at the Underwater Temple, he changed his suit for a white tunic with an indigo stole hanging from his shoulders.
