The first full day at Comic Con was filled with panels and big, Hollywood news. But what’s far more interesting than whether or not Guillermo del Toro is directing The Haunted Mansion is what people showed up to the San Diego Convention Center wearing. Comic Con is one of the few places series geeks can let their freak flag fly, and every year, they do.

Below you’ll find our full gallery of costume photos captured around the convention on Thursday. Browse through them all to see computer progams, Slave Leia, Spider-Man, and all manner of whattheheckishewearings. Check back in our Comic Con feed tomorrow for even more costume photos from Day 2.
