5. Tim Flattery's Unused Penguin Designs
One of the more memorable moments in Batman Returns was the use, by the Penguin, of actual Penguins, rigged with rockets, to attack Gotham City. It was not the most practical scheme, I'll admit. Even as a child, I thought it was somewhat ridiculous. How were the penguins aiming? That aside, it worked in the movie, which I actually thought was a worthy addition to the catalogue (not to mention serving as my first introduction to who Batman was, as a character).
Not entirely surprisingly, however, the movie originally did not limit itself to rocket penguins. Behold - Buzzsaw, Boxing, and two different Grenade penguins!
I think my favorite thing about these designs is the fact that some of them appear to be posing as people, wearing shirts. "Nothing to see here," they seem to be saying. "Just your average regular penguin tourist..." *BOXING GLOVE!* Sure,
that's what'll finally take out Batman.
