Metalocalypse: Army of the Doomstar (2023, Brendon Small)

Nathan is supposed to write the song that saves the world, but never got around to it (this would make a good double-feature with Bill & Ted 3). Murderface becomes possessed by evil. That cocaine clown is back, and the producer guy with bionic eyes. Sweet ending: “We forgive you, Murderface. You bring balance to this band by sucking. You suck so fucking much we can’t live without you.”
