Quote: I'm just wondering. Since the cosmic cube seems to be able to rewrite reality at whim, how does it compare to the Infinity Gauntlet? Is the IG the most powerful weapon or item in the Marvel Universe? I think that a cosmic cube would come behind. How many are there anyway? Can't a Cosmic Cube resurrect the dead? If so, that's pretty powerful.
As said by the other poster, continuity varies. In theory the Cube's can do essentially anything. However, the Cubes have internal blocks or limits on themselves. So there are often things they will *not* do, even if they *can* do it. Infinity Crusade goes through this in detail.
The Gauntlet has no such restriction. While the gems have a consciousness in them, they don't seem to care what people choose to use them for. Additionally, the gems are alleged to be the ultimate control of their universe. So if the cubes want to do A, and the gauntlet wants to do B, then B would win out.
Both objects are capable of controlling at a universal level.
Marvel established that there were levels of infinity, so the cubes were at one time inferior to the Celestial themselves!
