Energy Battery Gloves

The Energy Battery Gloves is a Hands armour piece associated with the intergalactic villain Krona. The gloves were originally developed by Krona as a predecessor to the Lantern Power Ring, upon voice activation the gloves are powered by a connected Energy Battery Backpack which taps into the emotional spectrum and channels the spectrum's power into the gloves to be used by the wielder.

It's association with an iconic DC character and its rarity classifies it as an Iconic Equipment item.
