Summary
Leon is a young boy who harbors a deep distrust of adults and society, a sentiment stemming from his survival of a war that claimed the lives of all adults, including his parents, leaving only children behind. He travels on a snowboard and possesses the ability to manipulate air, allowing him to suffocate opponents and control air currents. His Tao Power is known as "Wind". In the anime, Leon is part of a group of orphans that includes Tim Vertical. Having been constantly ignored or abused by the adults in society, he sought greater power to better protect his friends. Ironically, after gaining this power, he had to leave his companions behind to help the Apostles remake the world. Nearing the end of the story, Leon volunteers to retrieve fireworks for Eve, hoping to trigger a reaction that prevents her from uniting with Eden. He is saved by Train when he reaches the limit of his strength and is about to be defeated by two monsters from Eden.
