Regarding the recent episode... what's the story behind The Question and Powergirl? That is the official story in the current DC continuum?
The Question is a relatively minor character in the DC universe that I honestly would love to see gain some popularity. His biggest claim to fame is probably that he was the inspiration for Rorschach in Alan Moore's Watchmen. He started off as a Steve Ditko creation in the 60's and appeared in issues of the Blue Beetle for Charlton Comics. In the early 80's, DC bought the rights to the Charlton heroes. Alan Moore was originally going to use these characters in Watchmen, but ended up using knockoff characters because what he intended might have screwed with DC's potential to use some of them in future comics. The Question came back in the late 80's with a three year run written by Dennis O'Neal. In it, the character was changed from a right-wing nutjob who just went around beating criminals up (at least that's my understanding; I never read the Charlton run), to using more philosophy and disciplined martial arts. His real name is Charles Victor Szasz, but he goes by Vic Sage. His day job is as a TV news reporter for KBEL in Hub City, where he often gets scolded for not pulling punches in reporting the truth. As his name would imply, curiosity is his main motivation. The Question alter-ego is simply used to do things that Vic Sage can't, namely breaking the law in following up leads on this issue's villain.
From this episode, you might have guessed that he has no super powers. Basically, his abilities are martial arts skills, as he was trained by Richard Dragon. Also, the gas pellets you saw were developed by Aristotle Rodor, basically his assistant, and cause the plastic mask he wears to bond to his face. Also, it can change the color of his clothing and hair. And that's pretty much all he has in the way of abilities.
He hasn't been seen much since the O'Neal run, although he does appear from time to time. He was in The Dark Knight Strikes Again, for one. He was also in the Batman/Huntress story Cry for Blood. Other than that, he appeared very sporadically. Although I do believe he is getting a six issue mini-series starting in November.
