The Comic-Con dress code

The world's most famous pop culture fan convention descends upon San Diego July 8. Hall H will be mobbed. The sun will beat down upon the nerd hordes without pity. But there's one part of Comic-Con that never gets old: The fan costumes. Here's someone dressed as an anthroporphized Pinkie Pie from My Little Pony. (Photo by: Corbis)

Twi, twi again

Every Star Wars fan knows that Twi'leks are underrated in the galaxies far, far away. This con attendee told a photographer that she was dressed as a Twi'lek named Kri'nahi. (Photo by: Corbis)

It's only logical

Star Trek is a huge franchise at every Comic-Con, regardless of whether there's any Trekkie fare in theaters that year. Bonus: Federation uniforms are a lot easier to find and wear compared with, say, any other franchise. (Photo by: Corbis)

Layers of fandom

No velvet ropes on Asgard

The great thing about Comic-Con: No barriers between fans. A denizen of Asgard can rub shoulders with a ... whatever she is. (Photo by: Corbis)

No joke

Blue in the face

Ever heard of Andorians? If you're a true fan–the only kind at Comic-Con, of course–you sure do. For the uninitiated, Andorians are a race in the Star Trek universe. (Photo by: Corbis)

But can you run in that?

Not every Comic-Con attendee worships the mega-franchises. Take this woman, whose costume honors the 1976 sci-fi classic Logan's Run. (Photo by: Corbis)

Hellgirl!

Traditionally, the comic book superhero Hellboy is just that: A boy. But at Comic-Con, imagination trumps all the rules. (Photo by: Corbis)
