The Joker from the movie "The Dark Knight" (as portrayed by Nick Frederickson, 25) and Harley Quinn (20-year-old Stephanie Horner), his sometime-girlfriend and psychiatrist from the comics, cartoons, and the video game Arkham Asylum. Both Frederickson and Horner are from Anaheim, Calif. Horner made their costumes, with the Harley Quinn outfit taking more than 170 hours of work, she said.
Denver resident Liz Welch, 21, dressed as a custom-designed Star Wars Snow Trooper, while her friend Thomas Beyer, 33, created a Boba Fett-inspired character he named Solos Kyr. From Phoenix, Beyer got interested in making his costume when he started making one for his son. The costume pictured took him three months to put together, and he noted that he'd just finished the gun holster the day before the convention.
Wonder Woman as portrayed by 22-year-old Brittany Weckerly; Caroline Knight, 20, dressed as Vampirella; and Lizzy Brattland, 23, costumed as a Cenobite from the Hellraiser movies. All three are from San Diego, and each day of the convention they wear different costumes.
Well-known for their convention appearances, the West Coast Busters are, from left to right, Bryan Fear, 42, as Peter Venkman; Jeffrey Kirby, 28, as Ray Stantz; and Eric Eseke, 37, as Egon Spengler. Their replica Ectomobile, with the California license plate "Ecto I," is a fully functional 1959 Cadillac Miller-Meteor limo-style endloader with an ambulance conversion, and took five years to convert to its current state.
Though the first comic with the new version of Supergirl has yet to be published, 23-year-old Nicole Marino from Staten Island, N.Y., made a costume based on promotional images DC Comics has released. The new version of Supergirl debuts in September, as DC Comics relaunches all its superhero comics.
Though not practicing strict cosplay, these women were hired to walk around the convention wearing backpacks that powered videos playing above their heads. It made for as striking a sight as some of the costumes people were wearing.
