The Vault Hunters finally arrive at the Vault only moments too late to stop Steele from using the Key. When the Vault opens, a giant monster emerges and wipes out Steele and the rest of her troops. The Guardian Angel explains that the monster is called the "Destroyer" and was imprisoned in the Vault long ago by the Eridians, the alien race who left behind the ruins and created the Vault, in order to prevent the destruction of the universe, and that the Guardians were posted to prevent anyone from opening it. Although the Vault Hunters kill the Destroyer, the Vault is re-sealed for another 200 years. The Guardian Angel is revealed to be transmitting her signals through a Hyperion satellite in orbit high above Pandora. The game ends with the satellite sending a signal to a Claptrap robot on the planet, changing it into an "Interplanetary Ninja Assassin" (continued in the plot of the DLC "Claptrap's New Robot Revolution").
