“Quantum and Woody” follows Valiant’s laughable brothers (by way of adoption) as they return to Washington. They are as estranged as two people can be — well, as estranged as two people can be who must clang their band-wearing wrists together every 24 hours to avoid evaporating into nothing (the accident that gave them their powers came with that setback).

And who will the duo be up against in this new series? “Each other,” according to Kibblesmith.

“They can’t really break up. They’re joined at the hip. Almost literally,” Kibblesmith told The Post. “Part of that tension is, how long can you really keep up the silent treatment when you have to see this person every day?”

The reason for the brotherly beef is family. Investigating the murder of Quantum’s (Eric Henderson) father — who adopted Woody (Woodrow Van Chelton) — turned the siblings into a co-dependent superhero team. A secret about Woody’s biological father threatens to end their bond for good.

“Eric found out who Woody’s birth father was and maybe selfishly, maybe for his own good, decided to sit on this information and allow Woody to continue to believe Eric was the only family he had in the world,” Kibblesmith said. “They’re broken up when we see them. This arc is about whether that rift can be healed.”

Woody is ready to go out and search for the father he never knew he had, a man Kibblesmith describes as a “drifter” who is in Australia. The hold up is his brother Quantum, who, because of that whole “wrist clang” thing, must be a willing participant in said trip. And while it may appear Quantum doesn’t want Woody going on a trip that could be emotionally scarring, the self-imposed travel ban is actually much more selfish.

“The reason Woody can’t pursue [his biological father] on his own is because Eric refuses to do the 24-hour flight,” Kibblesmith said. “You have this extremely practical reason that they’re fighting and it’s sort of two stubborn people playing the role of an unstoppable force meeting an immovable object.”

Though Kibblesmith has written many jokes inspired by Washington over at “The Late Show,” he says his first few issues of “Quantum and Woody” won’t focus too much on the political and monumental surroundings in their return to the nation’s capital — at least for now.

“The first arc is really about where these guys have been in the meantime and the deterioration of their relationship and the sort of pseudo-road trip that brings them back together,” Kibblesmith said.

That doesn’t mean that the brothers won’t be mindful of their location in the future however.

“There’s so much satire in the book and it sets [Quantum and Woody] in an environment where satire is inherent to the setting,” Kibblesmith said. “I’d be an idiot if I didn’t have them bouncing off of familiar monuments and poking fun at our actual society.”
