Overexertion is problem that some Protectors accidently encounter when a situation forces them to make over use of their powers.
The Symptoms of Overexertion vary from person to person but generally follow the same pattern:
- Bleeding from the nose and ears, this is the most common sign and most people usually find a way of stopping their power usage at this point. Can also be accompanied by bleeding from the eyes, blurred vision, temporary blindness and/or coughing up blood..
- Usually spasms or fits, this occurs only if the subject continues to use their powers for a long period of time after being in step 1, and usually does not occur until after Powers have ceased being utilised.
- After the spasms and fits a patient can fall into a coma based on how long they spent within the first stage, this rarely happens due to there being other ways of taking out the opponent.
- This stage occurs after the patient has been in a coma for three to four weeks and only if the they spent around two hours in stage 1. The Patient will wake up briefly with memory loss from between an hour before the event and a year but they will still seem fine for a couple of days before they will suffer a stroke and heart attack simtaniously.
