Nano Gauntlet

The Nano Gauntlet was a gauntlet capable of holding the Infinity Stones. A facsimile of the Infinity Gauntlet, the Nano Gauntlet utilizes nanotechnology and was created by a team comprising of Tony Stark, Rocket Raccoon, and Bruce Banner.

The Nano Gauntlet was created to undo the effects of the Snap. Banner ultimately undid the Snap in the Blip. The Nano Gauntlet was used again in the Battle of Earth, when Stark eliminated all of Thanos' army using the Nano Gauntlet, sacrificing himself in the process.
