Malachai Nicolle and Ethan Nicolle are working on the second Dark Horse Comics-published series President of the World.
"The new Axe Cop miniseries President of the World is a follow-up to Bad Guy Earth," said Ethan.
"It picks up right where Bad Guy Earth leaves off, when Axe Cop is made the president of all presidents."
The comic is illustrated by the cartoonist from a story devised by his 8-year-old brother Malachai.
The pair launched Axe Cop as a webcomic in 2009.
"This miniseries, much like Bad Guy Earth, was created during a month-long visit with Malachai," continued Ethan.
"It includes a lot of new characters, good and bad. It's apocalyptic and charming, just like a good Axe Cop comic should be.
"Obviously, way back when we wrote Bad Guy Earth we did not plan for an Axe Cop comic about his presidency to come out right in the middle of the elections, but that is what happened. Perfect timing."
Axe Cop: President of the World #1 will debut on July 25.
