Another common entity in the Power Rangers Universe over the years has been the Power Cannon/Blaster. Whether it’s the combination of weapons or a stand alone cannon these weapons prove to be an essential component to any Rangers’ arsenal! Let’s start from the very beginning with the first cannon, the Power Blaster.
I have included links to videos of the cannons, just click the cannon name, courtesy of RangerCrew Media!
