TODAY, GENE LUEN YANG ends his 10-issue run on writing the Man of Steel, as Superman’s 50th issue hits newsstands virtual and physical.

The writer and two-time National Book Award finalist (“American Born Chinese,” “Boxers & Saints”) said that the experience of writing a monthly superhero book was demanding, particularly because he comes from the world of graphic novels, yet indelibly fulfilled a longtime professional dream.

“It was really a challenge, but also a learning experience,” Yang told The Post’s Comic Riffs. “I didn’t go in on my own. I was a part of a team with editors and writers who are much more experienced with [Superman] than I was. That was huge. That was an incredible help.”

Creatively, Yang inherited a Superman who was de-powered to a degree. There was no secret identity beneath which Clark Kent could take a break from the superman “S” and cape. There wasn’t even a cape. Even the S-curl had been buzzed off.

Despite that, Yang said the situations that his Superman/Kal-El/Clark Kent faced during this run were nothing that the hero hadn’t faced before.

“Superman is such an old character that he’s gone through these different eras,” Yang said. “He’s gone through eras when he was a lot less powerful than we think of him today. He’s gone through eras where he’s practically like God.

“Power-wise, we weren’t really doing anything new, but what we really did want to show is that regardless of what happens to him, that the core of the character stays the same,” the Bay Area-based writer continued. “He’s always somebody that doesn’t give up, and he’s always somebody that put others before himself.”

Eventually, as the covers for Yang’s Superman No. 50 reveal, Superman gets back to basics with his powers and returns to his more standard look. Yet Yang hopes that his run spotlights that despite Superman’s not being so super for the last 10 issues, there’s not much difference amid the heroics whether the character’s less than powerful or all-powerful.

“The theme was: The core of him doesn’t change, no matter how hard his life gets,” Yang said. “So what we ended up doing in [No.] 50 was sort of reinforcing that visually, by giving him his cape back, giving him his s-curl back. We’re … visually saying: He didn’t really change throughout all the stuff that he went through. He didn’t change at the core of him.”

Yang — who wrote the superhero graphic novel “The Shadow Hero” as an extended project — emphasized that the quick pace of writing a monthly comic was a drastic change from the pace at which he can create his acclaimed epics and other longer-form comics.

“It’s definitely more fast-paced than the graphic-novel world,” Yang said. “Monthly superhero comics run on this really crazy schedule. My graphic-novel stuff, I’ll finish the script, then I’ll do the art, and a year later it shows up on the shelf. With superhero comics, the turnaround is much quicker, and I have to say “hats off” to the editors for being able to juggle all of that.

“I’m surprised editors can last more than five years at their job, just because things are so quick,” said Yang, laughing.

The speed at which Yang had to write his Superman scripts also produced a beneficial effect.

“There’s a theory that creativity is a muscle that responds to constraints, and having the constraints of the monthly schedule I think does unleash a certain kind of creativity. It makes you think on your feet,” Yang said. “I think it makes your subconscious work a little harder. I’ve had times when I’ve been working on Superman where I’ll go to sleep thinking about a problem, and when I wake up, a solution will be there.

“I really felt like, in terms of my creativity, it was definitely a workout.”

As for what themes Yang was drawn to, he views Superman as a form of American mythology. The writer says that because Superman is from another world and he is fused with American society, scripting these books gave Yang the chance to organically incorporate Asian folklore into his tales.

“I feel like it fits in with the theme of Superman,” Yang said. “Superman is from another culture. He’s rooted in this idea of otherness. And he’s also kind of a God. He’s like American mythology. He’s about as close to Zeus and Thor as we get here in America. So it just felt like it fit well to bring the gods of cultures that we might think of as other into a Superman book.

“And also I just think that through comics, we are so familiar with European mythology,” he continued, “it just seems like it was time to bring in some other cultures stories, as well.”

Yang said that Superman No. 50 — which concludes with the “Savage Dawn” storyline shared by multiple Superman titles — will explore the superhero’s past, present and future.

“We hope that in some ways, it’ll be a fitting issue for Superman 50 — that the story will fit [and] that it will give you an overview of the character, and it’ll also return the character in some ways to the visual iconography that we all know and love,” Yang said.

And Yang underscore how exhilarating it was to script Superman.

“This is something that I dreamed of doing ever since I was a little kid,” said Yang, who is the Library of Congress’s new ambassador for Young People’s Literature. “I feel incredibly lucky to have been able to do it, I’m grateful to the team I was able to work with, and I’m grateful to DC Comics for having the faith in me to have a go at it.”

Yang continues to create graphic novels, including a forthcoming one about a real-life high-school basketball team. So now that he’s written one of the most well-known comic characters, could he see putting himself through the monthly writing grind again?

“I do think that I’m intrigued by the challenges that monthly comics throw at you,” Yang said, “so I’m interested in continuing to explore that.”
