Another silly fanfic idea I'll probably never use...

[ffutures]

...The Marvel universe has its own version of Clara Oswin, and his name is Stan Lee. He seems to turn up somewhere in the background of most historic events involving superheroes, and his apparent age varies wildly - the 1940s version looks OLDER than the one that appeared in the 1990s etc. He's either a time traveller or someone with a LOT of eerily similar dopplegangers, either would bear investigation by e.g. SHIELD.

Use it if you want it, a credit would be nice.
