The AMEW bomb was based on technologies that they had developed many years before, utilizing an energy source so powerful that it could destroy stars. The aliens had abused it themselves, destroying their home planet and most of their own race. Those that remained were intent that no one else should share the same fate. They had tried to recover all of the energy they had spread throughout the universe, but were disturbed to find out humanity's attempts to utilize it much as they did. They tried to warn them, but those in charge refused to listen, so they sent an army of genetically engineered warriors to protect humanity from itself. The bomb that they hold in their hands could take out every planet and moon orbiting the Sun. Weiss deactivates the bomb, and the aliens promise to never again meddle in our affairs, and return Jane, Tyler, and Weiss back to safety.
