filtered against Evil, the Joker, and Moriarty
The Joker has obtained a substance we call Joker Venom or Joker Toxin. I strongly suggest not getting near it or hi if you can help it. Most of it isn't lethal but you will literally laugh yourself into a coma if inhaled. I don't know if he has the lethal version, but if he doesn't it's only a matter of time before he gets it. It is curable if it is the non-lethal version, but I'll need an anti-toxin. One problem, Bruce was the one who created it. Not me. I don't know what's in it. He's already attacked a bar downtown.
