The series debuted several preview pages over at TV Guide, in addition to new details from the creators.
"We noticed there wasn't really an origin story for the characters," Lee told the site. "What if we refined who these characters are? They're really cyphers in a way."
"The monsters are real," Giffen told them, in addition revealing that the first few issues of the book follow "how the group gets together."
On updating the characters' look -- specifically referring to the "hipster Shaggy" -- Lee said, "We knew it would be controversial...All these people saying, 'it's horrible, he's a d-bag,' and I say, 'wait... you look like this guy!' It's an unusual look, but it's to show he's visually distinct from the others, and not part of the mainstream."
Giffen joked, "Keep in mind, it's a comic book. If the book does badly... [Shaggy] shaves."
Lee also addressed the possibility of a crossover with the other Hanna-Barbera titles, like "Wacky Raceland" and "Future Quest": "There's a lot of thoughts shared, non-sequitors thrown out...We love doing world-building." He added, "....[there's a] dream sequence where Scooby finds himself in the Wacky Racelands....[The books are] stretched out not just throughout the world, but throughout time. That definitely leads to a world-building dialogue and discussion."
