Elyon

When Elyon is first introduced in the comics, it is as one of the main villains at the beginning due to her introduction as the Princess of Meridian and the middle of the first arc, but later becomes one of the main heroes and most important allies of the guardians in the comics. Within the Television Series, Elyon is introduced as a friend of the Guardians (specifically Cornelia) before becoming a supporting (though unwitting) villain. Elyon was redeemed and took her place as Queen of a rejuvenated Meridian at the end of Season 1. Season 2 saw her continued reign before she was imprisoned at the hands of Nerissa and drained of her powers. The combined efforts of the Guardians and the rebellion resulted in her freedom and restoration to the throne at the end of season.
