Head - 25th HISS Tank Driver
Body - 50th Night Viper
Web Gear - POC Cobra Shock Trooper
I like to combine MOS for Cobra Legion into one "Viper" character. So, to me, there shouldn't be any reason to have a "HISS Tank Driver i.e. 'the Enemy'" and a "Track-Viper." All Cobra Tank Drivers should be called "Track-Vipers." Same thing with Stinger Drivers and Stun Drivers, they should all simply be called "Motor-Vipers."
I understand Hasbro had to produce completely new figures with completely new names, but there was too much overlapping of MOS/Functions in the Cobra Legion, especially when each figure represented a "generic," army-builder character. Unlike G.I. Joe where each action figure was an individual character.
