I was looking through about the first 50 issues of G.I. Joe and I realized something. Grand Slam makes a few appearances, and is mentioned a few times, but you never really see much of him. Plus he just disappears until the more recent DDP series.
I wanted a good shot of him for the comic pack custom figure I plan on making. He was called with the team to oppose the Oktober Guard in issue 6, but once the team landed, it was Flash who was there. In the 30's when Hawk gave all of the original Joes desk positions, he called 8 people, who Scarlett said were all of the original team members. Ok, so the Vamp II had given Clutch New Life. Snake-Eyes V.2 had given that character more to do, Hawk was the one calling everyone, and Steeler was a tank jockey, but what happened to Grand Slam?
