Screw this. The Bowser Empire wants the aliens gone, so it sets the lens on it's cool space laser to wide spread and fires it magneticlly accelerated C02 laser. Seconds before the heat resistant lens is vaporized it spreads out the beam, destroying virtually everything where the alien fleet used to be. idk if there were any human casualties. Also I think I destroyed 30% percent of the astroid belt. Oh well. 

Someone calm me down before I go on a shooting spree with my space laser
