Not much is known about The Metal Yell as it is one of the least used flux in the series. The Metal Yell developed on Unadar and was possibly named due to the planet being covered in heavily industrial structures. The metal scream is named as it is because the players who use it let out a high pitched, wailing yell that has a metallic accent to it. Despite it's name, this Flux can also be projected from the player's arms and legs as well.
