Ravashol pulsar

An external view of the Ravashol Pulsar firing.

The Ravashol pulsar, developed by Dr. Ravashol, was actually intended to be a peaceful but powerful communications device that transmitted information through laser energy.

The Cylon Empire captures the gun and converts it into a very powerful weapon.

Captain Apollo leads a band of Colonial Warriors to the gun and destroys it (The Gun on Ice Planet Zero, Part II).
