Star Fox 2 features gigantic battle cruisers deployed by Andross' army known as Cannon Betrayers that feature the "Planet Cannon", a massively powerful laser cannon that, hence its name, can easily destroy planets like Corneria. This ship or at least a ship of a similar design would also appear in Star Fox Zero, known as the Salvadora.

Interestingly, the official Japanese Star Fox 64 guidebook claims that both Gorgon, known in Japan as デス・ボール (Desu bōru), or Death Ball, and Bolse are also equipped with Planet Cannons, with the former using it in battle against the Star Fox team at the end of Area 6 in Star Fox 64.
