I know there is / was a marvel RPG game but I am not sure if it is in print. Much like some people use figures to play d&d games I am sure you could do something similar with a marvel based RPG

There is also currently out a batman miniatures game. I do now know much about this but it is a much smaller scale then normal action figures. I would imagine if you change the rules a bit to match the scale of the action figures it would be very playable.

I know there are also some older RPG games based around the DV universe, marvel universe and TMNT. I had a bunch of these when I was younger but never ended up playing them.

If you have a better idea of what you are looking for I can try to think of some other ideas. There is a lot out there game wise that could be changed up to work with action figures. Most miniature based games could be scaled up to use action figures and if they have characters similar to the heroes you could just change the names a it (infinity seems like it would be good in this way)
