San Diego Comic-Con officially starts with preview night this Wednesday as the show floor opens, and chaos will erupt as attendees rush to the hundreds of retailer booths featuring collectibles that will only be sold at the pop-culture fest. From Mattel to Kid Robot, there is something for everyone from the most mundane, mainstream keychains to art pieces that can forever grace your rumpus room.

We've compiled some of our favorite SDCC exclusives that you may have to beg and/or bribe a friend to acquire for you. If you're lucky, some are available online now. We suggest you jump on pre-ordering your favorites ASAP, because most of these items will be sold out before the show ends next Sunday.
