Beat the "fake" final boss on Hard Mode with any monster other than Space Godzilla in order to fight the final boss. Beat the final boss to see the true ending.

Destroyah is one of the toughest monsters in the game. He can use an oxygen mine and you will be flying all over the place. However, it only goes in one direction. His only weakness is his lack of speed, but he is still very strong. If you can attack him at the correct moment, avoid his oxygen mines, and avoid his attacks, you can defeat him.

Press Down + B, then press Away + B. Keep doing this until you are close to your
enemy to hit them.
