[quote=@Kafka Komedy]Of course, it's not exactly in Bruce's character to like someone with fear toxin.[/quote]
I would think that a man who chose the bat to strike hearts into the criminals, a superstitious and cowardly lot, would not mind the use of fear toxin as long as it wasn't as strong as the usual "screaming city" level of potency the scarecrow is famous for.

That said, I'm thinking long and hard on a take of 'shocker' from spiderman. I always liked that he had no powers besides his tech and most importantly was that he was a career criminal. He never killed anyone deliberately and knew to give up when outclassed. On the other hand, I haven't seen too many actual supers claimed either. I might go for the big blue boyscout himself.
