WHEN IT came to Bizarro, writer Heath Corson long thought the imperfect clone of Superman had yet to reach his full comedic potential. There were, Corson was convinced, many more laughs to be mined.

So when Corson was pitching new ideas to his editor at DC Comics, he jotted down one concept on a whim  — the kind, he says, that no one “would be crazy enough to let me do.”

The pitch: Take Bizarro and Superman pal Jimmy Olsen and send them off on a road trip, a la “Planes, Trains and Automobiles.”

The verdict: DC liked the idea so much that the first book in a six-issue “Bizarro” miniseries hits newsstands physical and digital today.

“I love the character — I think he’s great fun,” Corson told The Post’s Comic Riffs. “I’ve always seen him done typically as a man-monster who is a reflection of Superman. And to me, there’s also this element of just this innocent — this guy who just wants to be loved.

“He’s just sort of big and lumbering and hulking, but he’s also just this raw nerve ending of emotion. He’s the guy who just wants to be loved and can’t seem to make any of it come out right.”

The first issue sees Bizarro and Jimmy on a road trip to “Bizarro-America,” a country otherwise known as Canada. Along the way, the not-so-dynamic duo will make a few pit stops across the DCU, the first of which places them in Superman’s adopted hometown of Smallville. There, Bizarro will come face to face with his first nemesis: a used-car salesman.

Corson said he tends to write his stories on the funny side. “Everything I do has some humor in it. I really wanted to do something that had some fun and throw back to that old age of comic books in the 50s and ’60s, and even back to [titles such as] Justice League International or Ambush Bug,” he said.

“These were books that I read growing up that I loved,” Corson said of his comedic approach to writing the series. “So I wanted to do something in that vein, and I was sort of looking for characters that had the elasticity to do that. And there’s only so many that you can really push and pull in that way.”

One thing that wasn’t so amusing to Corson was trying to write Bizarro’s dialogue — a language of opposites that Corson said was challenging to create.

“It’s really hard — it’s like trying to write three languages at once,” Corson said.

Clark Kent appears in issue No. 1, but despite promised Superman appearances later in the series, don’t expect the Man of Steel to take over the series, Corson said.

“Our focus [in the series] is on Bizarro and Jimmy,” Corson said of the miniseries, which teams him with artist Gustavo Duarte. “The instinct is to have Superman come in and save the day all the time, and I want to get us out of there. But we will see Clark and we will see Superman again.”

In exploring the funny side of Bizarro and Jimmy together, Corson said the Bizarro miniseries is a chance to explore DC Comics’s “best bromance since Blue Beetle and Booster Gold.”

“They’re a classic comedy team,” Corson said. “They’re best friends, but Jimmy is exasperated with him all the time. [Bizarro] is incredibly annoying, he’s tough to take, but he’s still his big ol’ best friend because he’s got a good heart.”

So what would Bizarro himself think of this miniseries? In his own words?

“I think Bizarro would think [this series] is terrible,” Corson said with a laugh. “I think he [would] hate it. He wouldn’t want absolutely nobody to read it because he ‘am’ so embarrassed.”

As difficult as it is to write, Corson said there is one benefit to Bizarro’s unique way of speaking.

“The great thing about doing a Bizarro story,” Corson said, is that “when you’re on Twitter, and everyone says how much they hate it, I can just [imagine] everyone is telling me how much they love it. I win no matter what.”
