Crystal Moonbeam

Crystal Moonbeam is a pegasus from Princess of Power (toyline). He and his sister Crystal Sun Dancer come from Crystal World. After coming to Etheria, Moonbeam guards Crystal Castle at night.

In the minicomic Across the Crystal Light Barrier, Princess Adora and Spirit arrive to Crystal World, where Moonbeam explains that anybody who touches the world changes into crystal. Moonbeam brings Sun Dancer, who knows how to leave Crystal World by air, so Adora and Spirit transform into She-Ra and Swift Wind and they all fly back to Etheria.
