Classic gaming characters
You can keep your Niko Bellics: for my money, the only real iconic video game characters were established during the 8-bit era. The Mario Brothers, for instance! They had a movie made from their antics and everything. Get some suspenders, some red and green shirts, and you're gold.
Too easy for you? Well, how about carrying a boom box around with you constantly playing the infectious background music from Super Mario Brothers? And then you should casually leap up onto nearby elevated surfaces when the opportunity presents itself. (Note: We are not responsible for injuries sustained during Mario imitations.)
