31 Unique and Fun Fandom Mashup Costume Ideas

There are plenty of people out there (like me) who have an intense devotion for two different fandoms. For the most part, these fandoms are kept apart and there's not much crossover — except during Halloween. Thanks to the creative minds of people who cosplay during Comic-Con, you have plenty of inspiration to combine your favorite fandoms. Maybe you'll choose the R2-D2 Hello Kitty idea or the epic mashup of Charlie's Angels and Chewbacca. Either way, what you see ahead will be a great jumping-off point to come up with a fun, unique Halloween costume idea.
