I think her weakness need to reflect where she is as a powerhouse. So, I think her weaknesses should be...


  • Magic piercing weapons - Mortal weapons can't harm her, a regular old sword or bullet isn't going to scratch her skin. However, she has been cut and stabbed, usually by magic or other worldly weapons. Medusa's sword, anything from Ares, weapons from Hephaestus, an Nth metal bullet from the Batman who laughs; so lets keep that. example: a magic sword is to wonder woman what a regular sword is to a human.
  • Magic poisons - Hydra venom/blood for example was so potent that it caused Herakles insane pain to the brink of death. This is where writer can get creative; villain has found a way to get some divine poison and tries to kill WW. Poisons can also act differently, different effects and ways to cure oneself. Hydra venom can kill the infected by tightening the breath or blood, where as Gryphon blood causes madness. Stuff like that.


These are weakness that are life and death, not something that can hurt her constantly.


Other weakness like Blunt force trama - Just like EVERYONE ELSE if you hit Diana hard enough she can be hurt. Problem is you need to hit her really, really, really, really hard. Or super advanced alien tech - Just like any other powerhouse that has been harmed by New God weapons or any highly advanced alien weaponry, Diana is effected as well. Should be par of the course.
