Sort of like this thread game:

But with more leeway.

Instead of choosing a specific character you pick a franchise (movie/show/game/etc.) and the next poster can pick any character of their own choosing from that franchise and post an image of them. They then choose another franchise, and on it goes.

The image doesn't have to come from R-34, but it must (obliviously) conform to R-34 rules.


I'll start:
Star Trek (The Original Series)
