Most Impressive Fans: Darren Moser’s Towering and Brilliant K-2SO Cosplay

There is at least a 97.6 percent chance that you will love this puppet cosplay.

Most Impressive Fans is a feature highlighting the amazing creativity of Star Wars devotees, from cosplay to props. If there’s a fearless and inventive fan out there, we’ll highlight them here.

Darren Moser was about 100 feet from the door at San Diego Comic-Con this July when he felt his life-sized K-2SO puppet pitch forward, suddenly detaching from the harness strapped to his chest.

The towering Imperial security droid was making a break for it.

Standing outside of the entrance to San Diego Comic-Con, a Star Wars cosplayer holds up the life-size K-2SO puppet he created.

Darren had built the hulking puppet with a full range of motion, to gracefully lope around exhibit halls or deliver the necessary slaps to any Cassian cosplayers who tried to mouth off. He had painstakingly recreated the glowing irises and turned a CGI character into a PVC-pipe and EVA-foam reality.

But before leaving his suburban Los Angeles home, Darren had failed to pack an emergency kit in case Kaytoo decided to rebel. “Now I always travel with duct tape and zip ties,” he says.

Finding himself alone with his creation, the technical analyst plopped himself on the sidewalk and started to improvise the kind of quick fix that would make MacGyver proud, criss-crossing the straps of the harness to hug the puppet to his body, then seeking out friendly cosplayers inside who could help with a more long-lasting solution.

Congratulations, Darren was being rescued. With borrowed Gorilla Tape lashing them together, he and the 7-foot-2 puppet were able to spend the next seven hours walking the convention hall floor, posing with fans, and tracking down his official 1:1 scale Sideshow counterpart.

We caught up with Darren as he was preparing to once again step into the looming droid as part of the midnight festivities for Force Friday II.

More machine than man

Initially, Darren, 34, had aspirations of crafting a different droid — the clinking, clanking robotic bounty hunter IG-88.

“I enjoy making costumes and costuming,” he says. “It’s a wonderful time to be a maker. There are so many techniques and it’s become so inexpensive to really produce some amazing things.”

As a kid, Darren — now known online as Dr. Sci-Fi — crafted his own Rocketeer costume and other creations. In 2014, he enlisted with the 501st Legion, donning his stormtrooper gear for the first time on the Fourth of July. “Everyone loves a stormtrooper,” he says. But it was over 100 degrees as he and his garrison walked three miles in the La Verne Fourth of July parade. “My armor started to split a little bit from the glue melting, but I persevered and it’s been a fun ride ever since.”

When the first promotional images of K-2SO first surfaced in May of last year, he knew he’d found his next cosplay.

It was so early in the process that there were no photos of the reprogrammed security droid’s lower half. But even as more images were released, Darren found himself combing IMDB to figure out the heights of other Rogue One actors to compare and come up with his best guess on Kaytoo’s stature. “This is how deep I went,” Darren says. But still, information was limited. “I didn’t know how tall he was or even what his feet looked like.”

In his first sketches, Darren, envisioned encasing himself in the bulky droid’s torso, like wrapping his 5-foot, 11-and-a-half-inch human form in a faux-metal exoskeleton, and donning a pair of stilts. With the droid’s head hanging above his own, the costume would have been pushing 9-feet-tall.

He bought the stilts, but his human feet protruded strangely from Kaytoo’s stick-thin legs. “There’s nothing to hide that. And so from the side it looked ridiculous…it looked like he was wearing bell-bottomed pants or something.”

Frustrated, Darren sidelined the project to give himself time to come up with a new plan. “Building something that hadn’t existed in real life was a challenge.”

Kaytoo community

By the time Rogue One premiered, Darren had found three other K-2SO builders through Instagram.

With no tutorials or successful builds to serve as their Jedi Masters during the process, they made their own community, Darren says, troubleshooting individual projects with each other. Now the group even includes one cosplayer who took a more literal tack in developing his costume; instead of bringing the CGI droid to life, he created an ensemble that mimics actor Alan Tudyk’s motion-capture suit used on set.

Inside his living room and the carport at his Rancho Cucamonga, California, home, Darren went back to work on his own Imperial security droid, toiling from 9 p.m. to 1 a.m. “It probably took a whole year to build him, but so much of that is just thinking,” Darren says. “You know, there’s no blueprint for K-2SO. There’s no tutorial.”

Using the guidance of fellow Most Impressive Fan Jeremy Fisher, Darren fashioned a simple and lightweight PVC-pipe skeleton to support a wearable puppet much like the unfinished C-3PO that appeared in The Phantom Menace.

But instead of operating K-2SO while wearing a green-screen suit, Darren found a way to disguise himself while essentially melding with the character. Sometimes at troops, he wears his Imperial Officer gear, almost as if Kaytoo were marching in time and just ahead of one his human colleagues on Scarif. “It’s great because in photos I look like I’m an officer standing behind him. I went with more of the forest in the trees approach,” he says.

Sprinkler hose and grill paint

By New Year’s Eve, Darren had acquired dive fins to connect the puppet’s feet to his own and built the core PVC framework. He was ready to take Kaytoo for his first walking test.

“That was a big proof of concept,” Darren says, but the droid was far from fully operational.

Through a prop store specializing in mannequin displays for Halloween, Darren found joints that could fit onto the end of 1-inch pipe. “So that became his elbows and his shoulders and his knees.” After his first troop, Darren added a piece to cleverly locking the knees in place when puppet master and droid were standing still for photo ops.

He slid small mirrors into the puppet’s elbows, wrists, knees and ankles. “It gives that illusion for a moment like you’re seeing through it,” he says. “Although every Cassian I’m with always checks his hair in my freaking elbow mirror.”

So much of the early build was dedicated to online searches and wandering hardware stores, guessing at what might work and testing out his ideas. “I roamed the halls of Home Depot. That’s how I discovered K-2SO’s eyes,” Darren says, a combination that includes a 90-degree coupler for an aquarium, LED lights powered by button batteries and circles cut from milk jugs to provide the necessary fogged look.

Although the head itself was 3D printed, the rest of the form was covered in lightweight EVA foam, a favorite among cosplayers who need faux armor. “It’s very light, it’s very cheap, and it’s moldable,” he says.

But Darren didn’t want Kaytoo to stand around like a statue. After some guess work, he came up with a system of nested PVC pipe and sprinkler irrigation hose that runs along his arms almost like tendons, and other parts snaking back to a piece of wood at the puppet’s elbow that give Darren the ability to manipulate a set of controls that open and close Kaytoo’s hands. “When I squeeze, he squeezes. But it requires a lot of effort,” Darren says. “He has no grip strength, really, at all. I mean, in the movie he can pick up a stormtrooper. I don’t know if that can happen in real life. He’s more intimating than physically strong.”

When he upgrades the droid, a project he affectionately calls K-2.0, he hopes to finesse the hands so it takes less of his own muscle to make them function and upgrade other components like a motorized pan-tilt for the head to swing around.

But as spring wore on, Darren was running out of time.

After missing his first self-imposed deadline to debut the puppet at WonderCon in March — “I remember thinking, ‘Oh, I can get this done in a week!’” he says with a laugh — he was getting down to the wire for his hopes of bringing the droid to a 501st event at the end of May.

In the last three days, Darren says he sealed the foam coverings with liquid latex, then doused his creation in black matte paint marketed for BBQ grills.

Finally, he spent the final hours leading up to the event using a silver Sharpie to add in the nicks, scrapes, and  signs of wear that typically come with being a member of the rebel alliance.

Find a crew

By the time the puppet was complete, the costume had cost him about the same as a full set of screen-accurate stormtrooper armor, somewhere north of $1,000, and the puppet weighed about 50 pounds.

“He almost did me in that first day,” Darren says. “The problem was I was holding his weight the entire time.” Darren hadn’t yet installed the mechanism to lock the legs, so he was shouldering the full weight for the entire event. “I had to estimate my energy to have enough energy to make it back to the changing room and not collapse.”

Even with the modifications, manipulating the bulky droid all day is tiring. “He’s a workout, that’s for sure,” Darren says.

Among his more high-priced accessories, there’s an iPad mini lodged in the puppet’s back, a hub of controls that gives Darren a view of what’s in front him via a small spy cam in the puppet’s cheek and helps change Darren’s regular voice into something more character-appropriate. “He’s got a great salty personality which is tons of fun to play. Actually, I sometimes have to tone it down because we’re taking pictures with my fellow cosplayers and I’m making them all crack up.”

If you’re wondering, he doesn’t try to channel his best Tudyk-as-Kaytoo impression. “I do a voice because I really want him to be able to talk. It’s really important for interacting. But it’s just kind of a dialed-in robovoice.”

Friends dressed as Jyn Erso and other Rogue One characters typically act as handlers, to help him maneuver through crowds and signal when he needs to crouch to meet an adoring young fan on their level. “I love the physicality of him because it lets you interact so much. And kids love droids!”

But Darren has some advice for other Kaytoo creators.

“Travel with friends. Don’t got to Comic Con by yourself with a giant 7-foot-2 robot. It’s probably not the best idea,” he says.
