Helios

   As the evil Dead Moon Circus hunts for him, he runs to take refuge in the protective warmth of a young senshi's dreams ... who, even ChibiUsa herself, could imagine that a growing friendship would evolve into the most astute romance in BSSM?
  Helios is the high priest and ruler of the land called Elysion. His gem, the Golden Crystal, was desired by an evil queen named Neherenia. Once she had the Golden Crystal, she would be able to conquer Elysion and Earth at the same time. When Neherenia sent her henchmen, the Dead Moon Circus, after Helios, he took the form of Pegasus and hid in ChibiUsa's dreams for safety. It's in her dreams that ChibiUsa meets Helios, and creates a distant friendship that is soon to come closer.
  Pegasus gives ChibiUsa a crystal ball that she uses to talk to Helios most nights, especially after a battle. Pegasus had given Usagi and ChibiUsa a new henshin, and a crystal carillion ... "If you ever need me, call me on that bell." SuperSailorChibiMoon then uses the bell to summon Pegasus for aid in her SuperS attack, Twinkle Yell.
  Pegasus is a very kindred soul, and loves ChibiUsa with all his heart. Sometime after, ChibiUsa truly decides that she loves Pegasus, and when she becomes all grown up, Helios will be her prince.
  As apposed to Usagi and Mamoro's relationship, ChibiUsa and Helios' is more honest, steady, and compassionate. It's not because of the great difference in their ages that gives Helios the instinct to protect ChibiUsa, but that he really, truly does love her, and opposite to what some might think, it's not puppy love. ChibiUsa and Helios' passion for eachother is what created to core of SuperS, not to mention the future of the princess of Crystal Tokyo.
