The first series figures were generally the most sought after, as they featured the four Ghostbusters in their original cartoon jumpsuits. Each figure came with a proton pack and a ghost: Ray Stantz came with the purple Wrapper Ghost, Peter Venkman came with the blue Grabber Ghost, Egon Spengler came with the yellow Gulper Ghost, and Winston Zeddemore came with the orange Chomper Ghost. The molds for this series were reused for later lines (with new paint jobs) and the ghosts made additional appearances as well. The figures were very durable, the notable exception being the pack's easily-broken proton stream. The toys stood about 4 and 1/2" tall with Egon (like the cartoon) being the tallest at 5", and all had 5 points of articulation.
There was a difference between the card art of these figures' first release and their second release a year later, in that they didn`t have the pink color on the figures background. A difference on the toys themselves was the Proton Pack's yellow "cable"; it came out down from the circular part of the pack and not from the center.
