Plot Induced Stupidity
Plot Induced Stupidity, or PIS, is when characters don't use their abilities or skills to the fullest extent as shown before, even within their personality ranges, for the sake of the story plotline. It makes lesser powered characters an actual challenge against higher powered characters in the comics.
Examples of PIS include Flash stories lasting longer than three panels, or Toy Man as a threat to Superman. Standard CBR fights exempt the contestants from PIS unless otherwise specified.
