Some of my Cobra Troopers have distinct Personalities. For Example, my Night Vulture is an assassin working for Cobra who is ruthless in the vein of Firefly. My Red Sand Viper is the Sand Viper Leader (I have yet to give him a name!) and another in the ranks of the truely ruthless.

Some Cobra's I'll give names (Chuck, Larry etc) but that's just to put a human face on them under those Viper helmets. But usually, 3-4 pages later they're TOAST!
