It is crafted by Toji, the Temple blacksmith and has to be earned from the Kaijudo temple by proving yourself to the Duel Masters. However, The Choten has used technology to create his own set of cybernetic gauntlets which drags the creatures to the wearer.
Ray’s gauntlet was evolved into a stronger form from the siphoned mana of Infernus.
In "Like Father, Like Son," it is shown that there is a special wrap that can be thrown on the Gauntlet that can negate the abilities of the Gauntlet. Alakshmi once used this on Raiden, but Masters Kimora and Nadia were able to get it off near the end of the episode.
