Description
Pegaso, also called Elliot, is a central figure in the anime season Sailor Moon SuperS. He is the dream form of a character whose true identity is Helios, the high priest of Elysion, a sacred kingdom hidden within the Earth that serves as the realm of dreams and is connected to Prince Endymion. As Pegaso, he appears as a small winged white pegasus with a single horn, and that horn is actually the visible form of the Golden Crystal of Dreams, a powerful relic he protects.

His background begins in Elysion, a once beautiful and peaceful land that was attacked by Queen Nehellenia and her Dead Moon Circus. Nehellenia wanted the Golden Crystal so she could break the seal that kept her imprisoned in a mirror world and regain her freedom and youth. She captured Helios, and his physical body was confined within her domain. Only his spirit was able to escape, taking the form of Pegaso. Because he could not survive long on Earth in that state, he sought refuge inside the beautiful dreams of pure-hearted people, hiding from the enemies who hunted him. He eventually found his way into the dreams of Chibiusa, known as Rini in some versions, and asked for her help while swearing her to secrecy.

In terms of personality, Pegaso is gentle, wise, and deeply devoted to his duty as protector of dreams and guardian of the Golden Crystal. He is also cautious and secretive, initially refusing to answer many of Chibiusa's questions because revealing too much could endanger her and because the truth of his identity carried great risk. Despite this reserve, he is warm, encouraging, and sincerely cares about the wellbeing of those he trusts. He offers guidance about friendship, love, and dreams, and he carries a quiet sadness born of his exile from his homeland and his longing to return to Elysion. His dream is to go back to his world and restore what was lost.

His motivations are driven by responsibility and hope. He seeks to protect the Golden Crystal from falling into Nehellenia's hands and to free himself from her curse so that Elysion can recover. He also wishes to help the Sailor Guardians defeat the Dead Moon Circus. To that end, he chooses Chibiusa as his ally, believing in the purity of her dream, and he supports the guardians by sharing his power with them.

His role in the story is essential. He appears to Chibiusa in her sleep and communicates with her through a magical crystal sphere that she keeps safely. When the Sailor Guardians face the monsters of the Dead Moon Circus, Pegaso emerges to empower them. He grants Usagi, as Sailor Moon, and Chibiusa, as Sailor Chibi Moon, their Super forms, transforming their transformation items and providing them with new weapons, including the Kaleido Moon Scope for Sailor Moon and the Crystal Carillon for Sailor Chibi Moon. His power also elevates the other Sailor Guardians to Super forms during the season. The Crystal Carillon serves as a summoning device, allowing Chibiusa to call on Pegaso whenever the guardians are in danger, and when summoned he lends his energy to their attacks so they can destroy the Lemures and other enemies. He is pursued throughout the season by the Amazon Trio and later the Amazoness Quartet, agents of the Dead Moon Circus searching for the golden Dream Mirror that would reveal his location. He repeatedly escapes their traps, and the souls of the defeated Amazon Trio are ultimately sent by his power to Elysion.

His key relationships center on Chibiusa. She is his closest friend and confidante, the only person with a dream beautiful enough to shelter him. Their bond deepens over the course of the season from a secret friendship into something more tender and romantic, with mutual trust and affection growing between them. Pegaso is also connected to Mamoru, since Elysion and the Golden Crystal are linked to Prince Endymion's kingdom, and he has a duty to protect that legacy. He additionally supports the other Sailor Guardians, particularly Sailor Moon, by granting them the power they need to fight. Nehellenia is his primary antagonist, the queen who imprisoned him and covets his crystal.

His development follows the arc of that relationship and his own restoration. Early on he hides the full truth of who he is, and Chibiusa worries that he does not trust her. When the Amazoness Quartet's magic briefly transforms Chibiusa into a teenager, she loses the ability to call him, which creates distance and distress between them, but the bond is eventually restored when her true dream becomes clear again. Near the end of the season he is forced to return to his physical body, and Nehellenia takes the Golden Crystal from him, allowing her to break free and plunge the world into darkness. However, the power of the Golden Crystal ultimately turns against her, and with the combined strength of the Sailor Guardians and the dreams of innocent people, Nehellenia and the Dead Moon Circus are defeated. In the final battle, Helios saves Sailor Moon and Sailor Chibi Moon when they fall from the sky, keeping them alive. With the threat ended, he regains his freedom and returns in peace to Elysion, while his connection with Chibiusa leaves open the possibility of a future reunion between them.

His notable abilities include flight, telepathic communication, and the power to enter and move between dreams. He can travel between worlds in spirit form and can pass through physical barriers, as shown when cages and traps meant to capture him prove useless. He can summon and direct the energy of the Golden Crystal, using it to transform and empower the Sailor Guardians, upgrade their weapons, and channel powerful attacks in battle. When he appears in the real world through the Crystal Carillon, he grants the guardians the strength to defeat their foes. He also possesses the ability to bless and transport the souls of the redeemed, as seen when he sends the spirits of the Amazon Trio to Elysion. His survival depends on the purity of dreams, and his power reflects his role as a symbol of hope, protection, and the importance of holding onto one's dreams.
