Comic Final

So in my Superheroes in Comic Books class (man, every time I say that I think how cool it is) there is no final, only a project due. Well, after much deliberating and whinig about how I don't know how to do anything creative, I decided on a project:

Candace and I have many, many of the Marvel Legends action figures and even more Transformers figures. So I thought, hey, why don't I use those to make a comic book-esque project. By arranging and taking pictures of them and using Photoshop or something to edit and add speech ballons, I could make something really neat!

Now I just need two things: One, a good story, and two, knowledge on how to make dioramas and use Photoshop to do what I want.

Can anyone help?
