Photos: WonderCon's Zap! Boom! and Pow!

SAN FRANCISCO--WonderCon returned to San Francisco's Moscone Center last weekend and these three Stormtroopers were kind enough to stand guard at the entrance Friday.

With an attendance last year of more than 29,000, WonderCon is the second largest comics convention on the West Coast (after Comic-Con International).

This slideshow offers a flavor of the event.
