From a purely scientific perspective, the notion that Gigachad could stand on a fly defies fundamental principles of physics. The average housefly (
Musca domestica) weighs approximately 12 milligrams and has a maximum lift force of 1.2 milligrams per leg, totaling around 7.2 milligrams of weight support across all six legs. In contrast, an average adult male human weighs around 70–90 kilograms, meaning the force exerted by Gigachad’s body would exceed the fly’s structural limits by a factor of nearly 10 million. Even under the assumption that Gigafly’s insect portion is significantly scaled up, the exoskeleton of a fly is not designed to support the weight of a dense mammalian torso.
Biomechanically, flies utilize indirect flight muscles, which are optimized for rapid wing beats rather than load-bearing. Insect physiology follows a principle known as the square-cube law, where an increase in size results in a cubic increase in mass but only a squared increase in structural strength. This means that even if the fly portion of Gigafly were scaled up to the size of a human, it would likely collapse under its own weight, making it biologically unfeasible for it to support additional humanoid mass.
