They're still among the most obscure.
How many issues was that line-up actually together for, as villains?
#12 is remembered for the pages of Mac dying, not OF.
I'd estimate that 70% of current comic readers have never read an AF comic, if not more.
90% of people watching the SHIELD TV series have never even heard of AF.
OF aren't THE most obscure team ever but I stick by the view that they're one of the most obscure villain teams in the MU; mainly because 3/4's are dead.
