Check out these great custom minifigs of The Black Hole Gang from Space Police III. Using a combination of largely official LEGO parts these come together with great effect. I really like the boss character in the back.
There's been plenty of discussion recently regarding the future of the Space theme. Rumors have some elements of Space showing up as a sub-theme of LEGO City next year. I'm hoping these fantasy space/sci-fi themes continue in some form.
