Those of you who run in Flash circles have probably heard of 'Flash Facts' before, and you may be wondering which Flash started them. The answer is… each of the first big three is a valid response.
The first appearance of Flash Facts comes in Jay Garrick's original comics, though they are not incorporated into the story. Instead, the comic would be interrupted by asides, like advertisements or science facts, and Flash Facts was one of those asides. So the concept started with him.
In universe, Flash Facts are something that the Barry Allen Flash actually says, in the cannon of the story. In his original comics, however, Flash Facts were still out-of-story asides, just like Jay Garrick's.
The first time Flash Facts actually became a part of the cannon was when Wally West took up the mantle, and started mentioning that Barry would bring up 'Flash Facts' sometimes… and that cannon has stuck around.
So the answer is all of them - all of the Flashes are responsible for Flash Facts. And that brings us to today where you can buy your own book of DC published Flash Facts… coming soon to a bookstore near you.
