Leech Man was the fourth Galaxy Droid built, intended as an adaptable soldier that would be capable of operating on any given planet, where he would absorb the life energy of his opponents for use in not only powering him but allowing the molecules that once existed within an enemy to aid his allies through the use of a powerful new source of energy. However it was eventually discovered that he was unable to handle cold environs, leading to the decision that he was too flawed for continued use, since most planets were outside of his threshold for temperature.
