Here's a great method for coming up with new ideas. First, make a list of at least 10 things that you think are awesome. If you can't do that, I feel sorry for you and you might as well not read the rest of this. Seriously, if you can't make a list of 10 things that you love, you should be out looking for things to love.
Now, take your list of 10 and start combining things on the list together. For instance, you might have robots and werewolves on your list, I do, so jumble them up in your head and see what comes out.
Let's say you decide to use those two. The most obvious would be an animatronic robot werewolf that someone might build for a haunted house or for some kind of Scooby Doo-esque trap for a van full of nosy teenagers. But, we can go deeper than that. Werewolves are based on magic, not science. So, when a werewolf bites something it becomes a werewolf not through some biological process but magic connected with the moon.
What if a werewolf bit a robot and that robot became a robo-wolf on nights of the full moon? What if it was all machines? What if it was a toaster or waffle iron with added wolfiness? What if it was only machines shaped like a human? It's magic, so it doesn't have to make sense.
See, all interesting thoughts.
Now take the items on your list and start combining them and see how they fit together. They are all things you love, so I'm going to assume you know something about them. If nothing works, try a set of three.
Remember, if you don't like the first thought you have, try fitting them together in a different way.
I'm off to write a story about half-toaster, half-wolves combing the countryside looking for human flesh to eat and bread to toast.
