Croix Meridies is a human female teacher of the modern-day magic, former best friend of Ursula Callistis, also known as Chariot du Nord, and a witch who unleashed Magitronics to shapeshifting into various hostile beings. Croix originally had crucible hatred to Ursula Callistis, leading to a major all-out engagement between good and evil, under Queen Beryl's command, and reclaim over the world. Croix Meridies made her sufficient goal to destroy all of mankind, the secrets of the Seven Words of Arcturus, and mysteries across the galaxy.
In the end, Croix returned one last time after the Noir Rod went out of control during the battle and sought out to push back against the evil forces in the galaxy. In a twist of fate, she later joined Ursula Callistis once again and joined the Celestial Federative Alliance as a valued ally.
