It's possible you might be misremembering or combining elements from different stories. Could you please provide more context or details about what you're thinking of?
For example:
* What comic book universe is this from? (Marvel, DC, Image, etc.)
* Do you remember any specific details about the character or the curse?
* Is there a specific comic book or series where you saw this mentioned?
With more information, I might be able to help you identify the superhero you're looking for.
