The Zukonium ray was a strong power source that could be used as a weapon.
The Zukonium ray was powerful enough to destroy a small moon but was primarily used as a strong power source for buildings and colonies. The Planetary Pioneers hoped to use Zukonium rays as a power source on numerous uninhabited worlds. However, Luke Skywalker was forced to use Zukonium rays to destroy a maverick moon that was on a collision course with the planet housing the New Academy for Space Pilots.
