Avengers: Infinity War - Official Infinity Stone Powers Revealed (And What They Mean)
2. The Power Stone
Power: Destroy anything in your path
Item: The Orb
Meaning:
A far more simple one this, as the Power Stone basically just does exactly what it says on the tin. It's a weapon, capable of massive destruction, which we've already seen in the MCU a few times. There's little subtlety to it. It's notreally expliclty mentioned, but it seems the Stone is the key to amplifying the other Stones' powers.
Difference To Comics:
What we haven't seen in the MCU so far is the Stone's ability to enhance the user. In the comics the Gem allows the user to access and manipulate all forms of energy; to enhance their physical strength and durability and most interestingly to enhance any superhuman ability. That would be incredibly useful in the right hands in Avengers 4.
