SAN DIEGO — More than 130,000 fans are expected at San Diego's Comic-Con during the next few days for autograph signings, TV and film presentations and toy shopping. But more than anything else, this fan fest is all about the costumes.

And while other entertainment confabs typically wind up with an award show honoring artistic content, Comic-Con's finale is an award show celebrating artistic costumes.

But fans at this year's Comic-Con weren't waiting until Saturday night's annual Masquerade Ball to strut their stuff.

Day One on Thursday saw the San Diego Convention Center come alive with all manner of heroes, villains and other assorted creatures, from "Sharknado" sharks to characters from the original "Kill Bill."

And oh yes, the "Star Wars" gang was in full force, too — as it should be. It was the Storm Troopers who helped start the Comic-Con costume craze light years ago.
