Noooo you all have it WRONG!
The best weapon , when fired, can eradicate a galaxy in 1 shot...did i mentions it's more rapid than a minigun? oh plus it has it's self destruct code, when ordered, it rips the space/time/continuam or w/e it called.
It's a weapon the size of a big heavy rocket launcher, but instead of rockets, it fires these particles smaller than a grain of sand. each can rip space and tear the very fabric of time with a radius the size of 8 galaxies. It has these small holes comming out the end to release the particles. The particles are named:
X666-v7-GM
GM stands for grey-matter and the rest i dont know stands for.
And the weapon its self is called:
GMP (grey-matter projector)
My guessing is that they create some sort of artificial black hole-related bomb the size of a speck... and it launches out of a two handed artillery gun. It collasps on it's self after being activated, then eradicates spacial matter on a galactic scale.
If you ask me, any doomsday weapon like this one is better than the above of which you guys posted.
This weapon is better than: any weapon that can destroy at 10,000 galxies and not much more
planet destroyers- rules out deathstar.
any doom1/2/3 weapons (all takes place on one planet at a time, no galactic scale here.)
any halo weapon including 900 halo rings that fire at once, which is not part of story.
even if there were 1million death stars (very unlikly to ever become that many) it wont even compare to even 1 of the 10,000 particles fired per 1 secound.
anything that dont have infinite ammo might rule out too.
anything that cant go on a galactic scale cant compete with this magnatude.
can anyone beat that weapon??? i bet not!
