Well it is an iconic ranged weapon.If the whole Death Star is a weapon, then this must be up there as well.
Well, the new movies had a whole death planet that might have counted if people liked the last three movies being just a copy of the first three.Well it is an iconic ranged weapon.Are there any iconic weapons that can top the Death Star?
True. As for the last three movies, I wish the producers used what had happened in the post-Episode VI books for those three instead.Well, the new movies had a whole death planet that might have counted if people liked the last three movies being just a copy of the first three.
Oh yes, his 'Feyd-Rautha in a metal speedo' depiction in the Lynch version of Dune certainly was a dagger to the eyes. Oh wait, you mean something else...They've already been listed, but Sting, Excalibur, Stormbringer, and lightsabers all belong on the list.
Others have mentioned the Death Star and A-10 Warthogs. To me, those would be combat vehicles/weapon delivery systems, although their main guns are in fact pretty iconic.
And the Macross' dimensional cannons.If we are going to include the Death Star, then we probably ought to also include the Wave Motion Gun from Space Battleship Yamato.
