Future Boy Conan

In the year 2008, a devastating ultra-magnetic weapon threatens the very existence of humanity, destroying half the world and causing widespread destruction. The earth's crust is severely damaged, and the five continents are torn apart, sinking into the sea. A spaceship carrying a group of people fleeing the devastation fails to escape, but one vessel manages to narrowly avoid destruction and crash-lands on a small island that miraculously survived the disaster. Years later, a young boy is born, a beacon of hope in a desolate world.
