In the SuperS chapter of the 90s anime, a winged white horse called Pegasus visits Chibiusa's dreams, though the creature is truly Helios, the young priest of Elysion sworn to guard the Golden Crystal. Hiding from the Dead Moon Circus, he becomes the girls' secret ally against the invaders.
Helios exists in two shapes. His genuine self is a fair young priest tied to Elysion, the sacred realm on Earth where he protects both the peaceful dreams of humanity and the Golden Crystal. When Queen Nehellenia captures and imprisons that physical body, his consciousness slips away to shelter inside Chibiusa's dreams.
Within those dreams he takes the guise of Pegasus, a white steed crowned with feathered wings. A single golden horn rises from his brow, and that horn is the Golden Crystal itself. He holds this equine shape while dwelling in Chibiusa's sleep and whenever he aids the transformed Sailor Moon and Chibi Moon in their Super forms.
Long before the Dead Moon arrived, Helios served as the honored high priest of Elysion and the appointed keeper of the mystical Golden Crystal of dreams, charged with keeping that treasure away from any wicked hand. When the envious Queen Nehellenia and her Dead Moon forces descended, they overpowered him and locked his body away as a captive. To keep the crystal's location hidden, he cast his spirit into a pure and gentle dreamer, adopting the winged-horse form to elude his hunters while he searched for the one soul able to draw out the crystal's full power. That search opens the events of the SuperS story.
As the Dead Moon Circus rummages through the Dream Mirrors of countless victims looking for him, Helios arms his allies for the fight. He grants Usagi and Chibiusa two instruments, the Moon Kaleido Scope and the Crystal Carillon. Ringing the Carillon lets Super Sailor Chibi Moon call out Twinkle Yell, which summons Pegasus so his light can charge Super Sailor Moon's Moon Gorgeous Meditation, the attack that wipes out many of the Lemures.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
As Elysion's priest and the crystal's protector, Helios commands considerable magic. He can turn into the winged horse and travel great distances on the wing, separate his soul from his sleeping body, and walk freely through the dreams of other people. His bond with the planet itself lets him feel when the world stands in danger.
Helios, the high priest of Elysion, was overpowered by Queen Nehellenia and the Dead Moon Circus and imprisoned in their tent. To keep the Golden Crystal hidden from his captors, he sent his spirit into Chibiusa's dreams, where he appeared as the winged horse Pegasus.
Pegasus is the dream form taken by Helios, a young priest of Elysion, while his spirit hides inside Chibiusa's dreams. In this shape he is a winged white horse with a single golden horn, which is actually the Golden Crystal itself.
The Golden Crystal is a mystical treasure of dreams that Helios, as high priest of Elysion, is sworn to guard from anyone with wicked intent. While he is hiding as Pegasus, the crystal takes the form of the horn on his brow.
As Elysion's priest and the Golden Crystal's guardian, Helios can transform into the winged horse Pegasus, separate his soul from his sleeping body, and walk freely through other people's dreams. His bond with the planet also lets him sense when the world is in danger.
Helios gives Usagi and Chibiusa the Moon Kaleido Scope and the Crystal Carillon. Ringing the Carillon lets Super Sailor Chibi Moon call Twinkle Yell to summon Pegasus, whose light then powers Super Sailor Moon's Moon Gorgeous Meditation attack.
