Mako

In a war-torn world of elemental magic, a young boy reawakens to undertake a dangerous mystic quest to fulfill his destiny as the Avatar.

"Long ago, in a distant land, I, Aku, the shape shfiting Master of Darkness, unleashed an unspeakable evil. But a foolish samurai warrior wielding a magic sword stepped forward to oppose me. Before the final blow was struck, I tore open a portal in time and flung him into the future, where my evil is law."
