In an infinite Universe, anything is possible. As Jeremy and his friends continue to live their lives at Kadic Academy while fighting a reinvigorated XANA and his forces, commotion is heard a world apart; for in that distant world six young Ponies, a young Princess and her husband, the Captain of the Royal Guard, and a Dragon have found something incredible, something unexpected, and something new: a computer unlike any they have encountered before, one that holds the keys to the mysterious virtual world known to Jeremy and co. as Lyoko. But with this discovery comes a price, and soon XANA begins attacking Equestria and threatening to destroy all life in it. In the end, it will take the combined efforts of both these new Lyoko Warriors and the original Lyoko Warriors to preserve harmony and peace in Lyoko, Earth, and Equestria.
