Morgana is a major character in the 1995-1996 children's fantasy animated series Princess Gwenevere and the Jewel Riders, where she is the main antagonist of the series' second season, voiced by Deborah Allison. Morgana and Lady Kale later both inspired the character of Dark Sorceress in Avalon: Web of Magic.
The mysterious, sinister, and seemingly eternally young Morgana was once the Queen of the Wild Magic and a leader of the ancient wizards who have been eliminated by the good wizard Merlin 1,000 years prior to the events of the show. Introduced in "Revenge of the Dark Stone", she first appears in person in the titular episode "Morgana" as she comes back to life by the power of the Dark Stone. She and the also revived Lady Kale then make a deal to work together against the Jewel Riders as Morgana hopes to find the Wizard Jewels, get her vengeance upon Merlin, and finally conquer Avalon, unless Princess Gwenevere and her friends stop them in time.
In the end, Merlin uses the power of the ultimate One Jewel, provided by Princess Gwenevere, to defeat Morgana once and for all. She gets trapped in magic forge and seemingly annihilated completely, leaving no trace of her and the four ghosts of other evil wizards. And, with the Dark Stone no longer existing, it seems this time nothing is going to bring her back again.
