Many recently released Hollywood films feature superheroes like Superman, Ironman, the Hulk, Optimus Prime, and so on who possess amazing superpower and defeat supervillains with unassailable commitment to moral justice. Interestingly, different superheroes possess and exercise their superpower in very different fashions. What is more, this aspect of their difference is intimately related to an issue that is lately in intense debate among metaphysicians of powers and dispositions, the issue of the possibility of intrinsic interferers with dispositions. This paper will (...) argue that a strong case can be made against this possibility when we give due weight to the commonsensical understanding of superheroes and their superpower. Whilst other arguments have been raised against the possibility of intrinsic interferers with dispositions in the latest literature, this will present further difficulties for those who accept it.
