Helios

Pegasus is a winged white unicorn and Helios is the priest of Elysion. Pegasus and Helios are two separate characters in the manga, but in the anime they are the same. In the manga, Nehelenia curses Helios into the body of his favorite horse. Thus, Helios is forced to appear to Chibiusa in this form. He is seen riding on Pegasus, separate from the body of his favorite horse when he says good-bye to Chibiusa. Unlike his anime counterpart, Helios also lacks any sort of definitive power. He does not lend power to anyone to do attacks, nor can he physically change form himself. He can only transport himself between worlds and fight the curse put upon him. While he guards the Elysion, he does not guard the Golden Crystal directly. He is aware of the existence of it, but it is not in Pegasus’s horn, but a part of Mamoru that only Mamoru can wield.
