Hi batgirl,
I like your post on Superheroes and Villains with PTSD. There's a DC superhero type that might have PTSD. His name is Deadshot.
**Possible Triggers in this Post.**
There is a good artile on him on wikipedia.org. Deadshot looks like a Dirty Harry/Clint Eastwood type anti-hero who "doesn't mind putting his life on the line" and "will risk dying to get the job done".

Probably therapists will tell me that Dirty Harry or characters like him aren't good for me to have as heroes. They aren't may heroes. don't worry.
But I remember buying the 4 part Deadshot miniseries in 1988 as a teenager. I was really impressed by how DC comics took a really grim story and a superhero guy and took a risk with it.
******[There are possible triggers in the wikipedia article.............
Such as..........In the story Deadshot's son is attacked in horrible ways + is killed]. But I liked the Deadshot miniseries, because the story took on really gripping adult problems-so the Deadshot miniseries had a plot that was more like Lethal Weapon [the movie] and not like a tame story like a 1970s "superman and aquaman coloring book". Regardless, I like Deadshot's character because he has real problems and is a BIG departure from a lot of DC's comic heroes and other comic heroes that are as innocent as Adam West's Batman.
Have A Good Day, Rob
