I think that what I always found interesting about Flash was that, at least according to the card art, Flash looked to be easily the most sci-fi-ish of the Joes. The other guys had machine guns and pistols and bazookas and crossbows, but not Flash. He had the thing that could burn through the armor plating on a Cobra HISS, and then cook the snakes inside. This was before I saw any of the GI Joe cartoons where as soon as the fit hit the shan everybody just reached for their standard-issue laser rifles and Flash just chilled in the ready room playing video games and reading Popular Mechanics.
The stupid thing is, through all this interest and love I had for the Flash figure, I never actually asked my parents to buy one for me. Oh well, the 25A version is good enough for me. Flash was only released as a single-carded figure, and was actually the one that got me wondering if it would be possible that Hasbro would released all of the Original 13 in 25A form. In fact, the 25A Flash figure was only the fifth version of Flash released since 1982.
