When you step back and consider all of the MCU’s gadgets and powers, there’s really only one item that can crown the list: The Infinity Gauntlet. Now, just to make it clear we’re playing fair here, we’re talking about the Stark Infinity Gauntlet from “Avengers: Endgame.” In other words, this is a bonafide hero gadget that is both made and used by the Avengers for altruistic purposes.
With that in mind, we’re putting the Infinity Gauntlet 2.0 at the top of the list for what are likely very obvious reasons. In the comics, the Gauntlet is overpowered in a manner that is difficult to even comprehend. Even in the MCU, though, where cosmic comic book powers are often toned down, the power the Gauntlet wields is mighty indeed.
It doesn’t matter if you want to restore half the life in the universe or summon a soda from the fridge without getting up from the couch — having an Infinity Gauntlet would make literally all aspects of life easier. It represents pretty much every power and tool on this list, all wrapped up in one shiny, fist-sized package. Thus, it could be useful in basically any situation a person might find themselves in. Not bad for a fancy glove!
