Healing Overdrive

Achilles Heel: Healing Overdrive by Senator Cybus

Note: this flaw is only suitable for characters with some kind of regenerative ability.
If seriously injured (reduced to 5 Hit Points or less), the super being’s over-taxed healing factor will start to malfunction; the hero will still heal at his normal rate, but the flawed regeneration will cause massive scarring.
The character will lose 1D4 P.B. every time he has to recover from such severe wounds. This loss is permanent: the hero’s healing factor will accept the scars as a natural part of his body, and not attempt to repair them. Moreover, it will prevent the removal of the scars through cosmetic surgery, restoring the body to its ‘proper’ form within minutes.
These scars will be present in any alternate forms that the hero can transform into. Obviously, this will reduce the effectiveness of powers like Shapechanger and Alter Physical Body.
