Kill The World

And all humans.

When someone destroys an entire planet for part of their plan or out of anger. As annihilating a planet will take an immense amount of energy and power, the one who aims to achieve this destructive goal either needs to be a role with high-ranking Strength or Skill, have access to an Ultra Space Laser, or be in touch with somebody who has the Galactic Annihilation superpower.

Contrast to Ded Planet. This UnTrash is generally about when a planet is destroyed while Kill The World is about destroying The Homeworld.
