What Do These Minis Have in Common?

This is the 2nd diorama piece that I want to do. This features Bath Time for Bubbles from Crocodile Games and three minis from Hydra Miniatures (their Retro Raygun line). The Hydra pieces are pretty simple (very reminiscent of the 1940 era sci/fi serials like Flash Gordon and Buck Rogers) so the paint work will have to be pretty smooth. They are also not the best castings, there is a fair amount of pitting in the metal. Fortunately the pitting is pretty light, buffing with the steel wool should take care of that and then maybe a filler coat of watered down milliput (something you can't do with green stuff). Bubbles, however, is an exceptional casting, a few light mold lines erased and she was ready to go.

Right now the working title is Time Rift, I'll let your imagination run wild at this point.
