C2E2: Have a game plan ready to navigate Chicago site

Winged, caped, one or two of them green-skinned, they streamed into a great hall sprouting massive concrete pillars — a scene that conjured a vast intergalactic visitor arrivals lounge.

They passed though a security checkpoint, displaying their blasters, battle axes and lightsabers.

They came in peace.

Hopefully they also came with a game plan to successfully navigate the vast maze of toys, curiosities, artists and celebrities inhabiting McCormick Place April 26-28 for C2E2, the Midwest’s largest pop culture convention. The best option is to download the event’s mobile app, which provides detailed maps, coupon books, schedule updates, notifications and more.

A particularly difficult challenge, it would have appeared, for Warren Swanson, 21, of Batavia, who brought along an 8-foot-long, 3D-printed Space Battleship Yamato from the Japanese anime series of the same name.

Swanson, dressed in the red-and-white naval uniform of the character Susumu Kodai, planned to wheel his creation around the convention all day Friday on a hand-built cart.

“This is my love letter to the (anime) series,” Swanson said.

But before he could share it, he had to get the thing in the parking garage elevator.

Easy, he said, showing how the magnetized hull could be broken down into various pieces. Swanson spent the rest of the day navigating corridors of glowing light sabres (from $99 all the way to $1,600), foam swords, cellophane-wrapped comic books and thousands of other glittery trinkets.

Conventiongoers also have the opportunity to get autographs and photos with favorite celebrities, which, this year, include actors Christopher Lloyd, Chad Michael Murray and Cristo Fernandez.

Passersby stopped Swanson frequently for a photo op — no mean feat in a place swarming with a dead ringers for Batman, Spiderman and Captain America, among hundreds of other fantastical characters meticulously brought to life. Swanson obliged, saluting and clicking the heels of his black leather boots.

Eileen Peterson’s problem Friday was that her world had overnight dissolved into a blur — the price to pay for becoming “Gwen,” a deerlike character from the video game “Spiritfarer.” To achieve the effect, Peterson, 34, wore white contact lenses with tiny perforations over each pupil.

“I have an idea of shapes, so I have an awareness of where people are,” said Peterson, who lives in Memphis, Tennessee. “If the landscape is changing, I have what we call in the industry, a cosplay handler,” she said, gesturing to her best friend, Toria Olivier, 34, who lives in Chicago.

Peterson said she’s all about authenticity.

“So I figured that being blind for a few hours was worth it to have good photos with my best friend that will be memories for a long time,” said Peterson, who was also wearing 3-inch heels.

Erin Cox’s challenge was keeping the cash in her pocket, in a place that can suck you dry in an instant — at least until you find the nearest ATM.

Cox, from Fort Wayne, Indiana, found herself in front of a booth that sold ultra-realistic light sabers, most going for hundreds of dollars.

“I want all of them,” Cox said, adding that she really didn’t need any. She said she brought her boyfriend along, at least in part, to warn her if she was getting a panicky urge to spend.

“It is overwhelming to look around. There are so many things that you want,” Cox, 31, said.

Steve Ormins’ hope was to survive intact for about two hours for a Chicago-themed tableaux with a group of friends. With wide Styrofoam wings taped to his arms, he looked as though he were trying out a doomed human-powered flying contraption. But when he study fully upright, he morphed into, of all things, the Daley Plaza’s Picasso sculpture.

It took him about one week to make the costume, Ormins said. He briefly considered coming as the “Rat Hole,” the North Side sidewalk imprint that’s now been removed. But he decided he wanted something classier.

“It’s way more iconic,” Ormins said of the Picasso.
