Inverted Immunity

Inverted Immunity (Major) by Senator Cybus

The super being has a strange adaptation to his immune system - more than just a protection against disease and poison, this ability lets the hero draw power from the contaminants in his body.
Any infection or toxin that the character is exposed to will have the opposite effect to what it should have: a head cold will improve his breathing and make him feel alert and energetic, excessive alcohol will make the hero more coordinated and rational, junk food will lower his cholesterol and so on. The duration of any contamination is unchanged, only the result. Note that the character never has to try to save against disease or poison of any kind; this odd immunity is automatic.
The effect is even more pronounced when the character is exposed to a particularly virulent contaminant - in game terms, anything that would normally result in damage or penalties. The toxin or sickness will restore (or, if the super being is already at full health, temporarily bestow) the amount of S.D.C. it should remove, and/or turn negative modifiers into positive ones. For example, if an opponent with the power of Pestilience (Powers Unlimited Three, page 86) tries to infect the hero with a fever, it will instead temporarily double his speed and initiative, grant two extra melee attacks/actions per round, double his combat bonuses and add a bonus of +30% to all skills.
Any disease or poison that should be instantly fatal will actually fully heal the super being, restoring all S.D.C./Hit Points immediately. Beneficial drugs will not have their reverse effect (so you can’t, for example, give the super being a headache by feeding him aspirin), rather they will have no effect at all - though with the hero’s incredible immune system, he hardly needs the help.

Bonuses:

+2 P.E.

+1 P.B.

Limitations: The character cannot draw strength from diseases or toxins he creates himself (like those produced by the powers of Pestilence or Venomous Attack); he can’t be harmed by them, but they don’t empower him.
