5. Enhanced Mortality
In series two, it is revealed that the Misfit's powers can inverse themselves and perform the opposite action of what was originally intended of them if the user takes drugs. For example, in episode two of the second series, the gang all take pills, reversing all their powers. Kelly verbalises every thought she has, Simon becomes the centre of attention and Alisha is repulsive to others. Nathan's inverted power? "Enhanced Mortality", (the opposite of his original 'immortal' power) which is just about the worst 'power' one could have. We're all mortal, of course, and our number could come up at any time, but in this particular episode, Nathan is, erm, extra mortal, and is more vulnerable to death than the average person. Which, you know, is terrific. During this period of temporary power inversion, Nathan is almost killed by shrapnel after a car explodes, but is fortunately spared by Super Hoodie and lives to tell the story.
