The robot masters from Mega Man 3 were co-designed by Dr. Light and Dr. Wily, So I'd assume they'd have industrial functions that were repurposed for combat. In this comic specifically, Snake Man was designed for, like Dr. Light said; Reconnaissance and Surveillance, which he uses those little Search Snake drones to do. If Dr. Wily were to reprogram him, he would probably modify the Search Snakes to have small explosives in the drones tip, which could be detonated at Snake Man's Command. But how likely to happen would that be?
