Ever get that feeling like you've seen someone before? On the left, Zartan, a mercenary often employed by Cobra Commander and a major enemy of G.I. Joe. On the right, Abbath, singer and guitarist of metal band Immortal. I'm fairly well convinced they're the same person. I think Abbath was a mercenary going by the name Zartan. When he was in between missions or during slow periods of hunting G.I. Joes he learned how to play guitar. His short stint as the frontman of the awesome Cold Slither further stoked his creative flames. After awhile the mercenary business grew tiresome. Subsequently he began writing music and left the mercenary gig behind to make thunderous black metal with the sons of northern darkness e.g. Immortal.
