power ring(green lantern) vs ultimate nullifier(mr. fantastic) vs infinity gaunlet(thanos)

whats the greatest weapon in the universe???

Infinity Gauntlet definately, you can control anything with it. Mind, which pretty much means you have virtually limitless psionic abilities including telepathy and telekinesis. Time, which means you can do anything from slow, fast forward or stop time, not to mention time travel. you could also mess with people’s aging. Power, where you have limitless duravility, strengh, and can manipulate energy. Reality, where you can change reality. Space, basically teleportation and interference with anything in motion. And Soul where you can pretty much steal souls.
