Trixie Lulamoon (Ed, Edd n Eddy XL)

"The Great and Powerful Trixie...!" - Trixie, about to finish her sentence in earlier episodes.

"I made it all up, Eds; the reason why I was your enemy was because Twilight doubted me and made me a laughing stock my whole life! She's the one who caused me to become the dictator the three of you knew me as and that she's the one who started this horrible war. I hope you can forgive me..." - Trixie, asking the Eds for her forgiveness.

"Don't you think the Great and Apologetic Trixie is the most forgiving unicorn in all of the Fourth Kingdom?" - Trixie, changing her name and becoming an ally of the Eds for the rest of the series' run.

Trixie Lulamoon (voiced by Kathleen Barr) is a female unicorn magician who is the main antagonist later revealed supporting protagonist in Ed, Edd n Eddy XL.

During the first four seasons of the show, Trixie was depicted as a boastful and arrogant unicorn magician who would use magical and underhanded tricks to try to dispose of the Eds, so she could claim the Fourth Kingdom for herself and that all she wanted was power, but it was revealed in the show's theatrical film, "Ed, Edd n Eddy XL: The Aperture War" that the reason why she was the Eds' archenemy from the very start of the series as a power-hungry and disrespectful snob was because that Twilight Sparkle doubted her all the time and that she was the true culprit behind Trixie's wrongdoings, thus making Twilight the true main antagonist of the series.

Trixie was described as boastful, power-hungry and malicious from seasons one to four. Now throughout the rest of the show's run, she is the Eds' most helpful ally and no longer called herself "The Great and Powerful Trixie", describing her as generous, friendly and disciplined.

Trixie is a blue unicorn pony frequently seen wearing a lavender-colored witch hat and cape with yellow and blue stars on them and a light blue gem strapping the cape to her neck. Her mane and tail have white and blue stripes (the mane is neatly groomed, but the tail is slightly scruffy in comparison) and she also has purple eyes.
