Well... I imagine I'm counted in that group, and rightfully so.
But like Alt said, there's probably a different on-ramp every wave or two based on ages of the fans. Some would argue there should be a Salvo on the pegs every year. Falcon and Jinx could be to some what Flint and Lady Jaye are in my eyes. Spirit feels crucial to me, and regretfully... Duke. Hawk, Stalker, Beach Head, Gung-Ho all feel like big standouts that were frequently featured on the cartoon. The comic did a great job of rotating in new characters throughout, and showcasing a lot of them somewhat equally, but Snake Eyes, Scarlett, Stalker, Storm Shadow, Cobra Commander, Zartan, Baroness, Destro, and the Dreadnoks seemed to remain in the spotlight throughout, even when some of those hadn't had a new figure in years.
