The Planet Cannon is a gigantic battle cruiser used by Andross in the unreleased Super Nintendo game, Star Fox 2. It was designed specifically to destroy Corneria. Direct laser fire by starfighters cannot damage it. The only way to bring down this massive behemoth is to take out the core.
- The Planet Cannon shares characteristics with Superweapons from other Sci-fi series: the Death Star II from Star Wars because you can only destroy it by attacking the core, and the Planet Killer from the Warhammer 40,000 universe which was almost identical in purpose and function but could engage other ships with it's primary and secondary armaments and could be destroyed by attack craft or enemy warships.
