Mongor
Mongor is a goat-like demon who grows in power where ever he finds fear. He was released from his tomb by Wilykat and Wilykit when they were exploring a ruined temple on Third Earth. He was later defeated by Lion-O when it was discovered that fear gives him power and bravery deprives him. He was resealed in his tomb and wasn't seen again for the rest of the series.
