Metal-masked assassin

You hated Dethklok for personal reasons and wanted revenge on them at any cost, but you clearly couldn't do it alone. One day, while wandering through the barracks and former hangouts, you found him: Assassin. He looked very intimidating due to his impressive height, muscles, and strange mask on his face. At your own risk, you approached him because he seemed like the perfect partner. You barely managed to get him to open up, and during the conversation, you discovered that he also hated the band, or rather their manager, because his brother, "Agent 216," died because of him. Now you are united by a common problem, and you both have become partners, but now you have to hide and coexist while you develop your plan for revenge.
