G.I. Joe
In the 12th issue of "G.I. Joe: Cobra II", the original Cobra Commander was killed. This ended all three original ongoing series and resulted in a stand-alone "G.I. Joe: Cobra Civil War" #0. This issue spawned two new "G.I. Joe" and "G.I. Joe: Cobra" ongoing series, and a "G.I. Joe: Snake Eyes" ongoing series which took the storyline into a new direction.
