Planzet (プランゼット) is a 2010 Japanese animated film written and directed by Jun Awazu.

[1] In 2047, an unknown, alien life-form, codenamed FOS, attacks Earth, destroying the world's major cities in one fell swoop.

The survivors unite to fight back, and three years later they erect a world shield, the Diffuser, to stop further invasions.

Taishi Akejima, a soldier in the Planetary Defense Forces Alliance, would like nothing better than a shot at the aliens responsible for his father's death six years ago.

However, the new offensive requires a powerful weapon to be deployed and the Diffuser to be disabled, leaving the entire planet terribly vulnerable once more.
