His name? Mo-Larr. His deal? He's the Eternian dentist to the likes of He-Man's archest of nemeses, Skeletor.

Mo-Larr, his pals from the Masters of the Universe as well as superhero and toy characters both mainstream and highly obscure play major roles in the pop-culture-spoofing shenanigans in the fifth season of Robot Chicken, which comes out on DVD and Blu-ray today.

The Emmy-winning show comes on in 15-minute doses Sunday nights at 11:30 as part of Cartoon Network's Adult Swim lineup, but fans can watch the second half of the season on the new DVD before the episodes air on TV.

To craft sketches such as Skeletor and other 1980s toy villains attending a self-help seminar, the heroes of G.I. Joe expanding their stable of animal sidekicks, and Gargamel going undercover as one of his hated Smurfs, Senreich, Green and others tap into the knowledge they've been building on since the days of watching Saturday morning cartoons and playing with action figures as kids.

Senreich is the resident Star Wars geek. Green is a master of G.I. Joe lore. Co-head writer and co-director Doug Goldstein is a Transformers junkie. And all the spoofs involving Gobots, Voltron, Silverhawks and other properties come up in conversations among the entire creative brain trust.

"Each of us have our own loves a little bit more than others," Senreich says. "But that said, we all are a product of this stuff. We know a little bit about everything, or enough to write about silly stuff with it.

"It's really just all of us reminiscing about our childhood or having casual conversations that probably every geek in America has with each other."

Getting celebrity guest voices such as Jon Hamm, Kevin Bacon, Nathan Fillion, Katee Sackhoff and others sound like the easy part compared to the animation process.

Once they get an idea for using a toy or a character, they often have to hunt them down, especially the obscure ones. But they quickly realized after starting the show that they couldn't use the toy because they weren't as poseable as the creators needed.

"Our animators would try to pose them, and after a while the joints became loose so they'd lose the flexibility and poseability of these characters so they couldn't hold the poses we were trying to animate them in," Senreich says.

Nowadays they'll body parts from the original toys in custom-making their own versions, he says. "The He-Man toys that you see, those bodies are not the bodies that are on the actual action figures."

In a little bit of toy fantasy becoming reality, Mattel created an action figure of Mo-Larr — who first appeared in the second season of Robot Chicken— for a San Diego Comic-Con exclusive set in 2010. (Senreich recently learned of a man who posted on his Masters of the Universe fan site about how a Mo-Larr action figure helped persuade his 4-year-old boy to see the dentist after severely fracturing one of his front teeth.)

And the character becoming a toy inspired Senreich and the Robot Chicken team to include him in more episodes.

"He's just so silly," Senreich says. "We just got giddy and excited knowing they were going to make a toy, and it just made us want to figure out more things for him."

Beginning next month, Senreich will be teaming with his friend, Justice League comic-book writer Geoff Johns, to work on a DC Comics-themed Robot Chicken special airing next year, which will be similar to the three Star Wars specials they've aired.

"We've done so much DC stuff in the past that I don't have a doubt in the world we'll do something even better," says Senreich, who, with Johns, sold two drama pilots to Fox in the early 2000s.

Fans at comic conventions always tell Senreich about what properties they should lampoon next, and everybody on the Robot Chicken team has their own, too. Personally, Senreich wants to do another sketch with Great Mazinger from Shogun Warriors, but they just haven't found the right one yet.

"It's what sparks it that starts the process. It's less about what toys we want to play with," Senreich says.

"I'm getting paid to play with toys. Whenever you have those really hard days where you're working 16 or 20 hours, you stop and you sit there and you're looking at your desk full of just toys everywhere. You just have to smile at that."

Senreich keeps a toy collection at home, too, and he's beginning to see his 2½-year-old son, Ryder, find favorites. While he's not at the point to start playing with a lot of toys, Senreich says his boy likes Minimates, knows who Chewbacca, Darth Vader and Green Lantern are, and wants to be Anakin Skywalker for Halloween.

"Two years from now, I'm going to bust out my old C-3PO carrying case and break out my original Star Wars figures for him to goof around with," Senreich says. "It's that sort of stuff that I'm excited about. I'm reliving the childhood experience through him.

"I'm hoping that Ryder will like the same things. But then again, I'm like, 'You know what, he's going to end up being a jock and only want to play football,' and that'll be totally fine also."
