The Full Metal Mayhem is one of the teams in Mutant Football League. The team was hinted in the Mutant Football League Console Launch Trailer. Their logo is a demon skull wearing a orange bandanna with yellow-orange wings and two guitars behind it. The team has a rock motif and all of its players are named after famous and classic musicians, bands, or songs. They are obtained by downloading the Demonic Legion Pack DLC along with the Cracksumskull Jugulars and the Sonic Blast and Time WarpDirty Tricks. Their stadium is Stairway to Heaven Arena (a reference to Led Zeppelin's "Stairway to Heaven"), located in Downtown, Purgatory (making it the second non-Earth venue in the MFL after Ceti Alpha Stadium).
The Mayhem is the newest team to be selected into the league, but it's not clear how they came to be. Rumors persist this is a supernatural team made up of undead & soon to be dead rock stars, while other whispers suggest advanced cloning techniques (with daily blood transfusions & Roid Rage booster injections). What is clear is that the Mayhem is one of the most popular & fierce teams in the league & they will rock you. (What's in the Demonic Legion DLC Pack)
The team is a possible reference to the anime Fullmetal Alchemist.
The venue that the Mayhem play in, Purgatory, is according to the belief of some Christians, an intermediate state after physical death for expiatory purification.
