Professional wrestler Sgt Slaughter served as the real-life spokesman for the G.I.Joe team between the years 1985 and 1991. He was immortalized as four different action figures, in animated form, in the Marvel Comics, and in countless promotionals for G.I.Joe. When one thinks of G.I.Joe in the 80s, it's impossible not to think of Sgt Slaughter.
