In the far future, Duel Monsters has taken a turn. Duelists no longer use the Fusion, Synchro, and Xyz Monsters due to them being forbidden from the game. Everyone now duels with green colored monster cards called Zeo Monsters. Yuko, the main hero, learns of the forbidden cards as he and his friends battle against The Legion, a organization who wants to shape the world into their own kingdom by using the forces of Water, Fire, Wind, Earth, and Chaos to destroy the current world. (The characters, story, and Zeo Monsters are all made up by me, so there shouldn't be any Copyright issues. Other than these things EVERYTHING belongs to the People who created Yu-Gi-Oh. If there are any issues you see throughout the story please tell me, so I can fix it.)

Stranded on a parallel Earth, the Tenth Doctor finds himself mentoring a traumatized child soldier enlisted in a hopeless war to save humanity. With an endless number of mysteries in sight -- from the enigmatic alien invaders they call Angels, to the strange machines known as Evangelions used in the planet's defense, to the shadowy maneuvers of those in power -- the Doctor is drawn deeper and deeper into a web of mistakes and sins that threaten to consume all humankind. In time, he'll face the darkest question of them all: what if there are some worlds -- and some children -- even the Doctor can't save?
