Like many fans I’ve always wonder what would happen if certain comic book characters were to somehow meet. For example, what would happen if Green Lantern met Space Ghost? Well if you’ve had the same idea, the wait is almost over! DC Comics has announced a few annuals that are expected to be released on March 29, 2017. They will crossover some of their mightiest heroes with many Hanna-Barbera properties.

DC will publish four different annuals crossing over the DC Multiverse with Hanna-Barbera.

First up will be Adam Strange/Future Quest Annual #1

It will be written by Marc Andreyko and Jeff Parker with art by Steve Lieber. It will also include a backup story by Dan DiDio and art by Phil Winslade featuring Top Cat!

Here’s what you can expect:

Following the events of the DEATH OF HAWKMAN miniseries, Adam Strange is blasted through multiple dimensions only to land on Earth! But instead of super powered beings and legendary crime fighters, he encounters a boy adventurer and his scientist padre father – and they’re the only ones who can help him return casa home. Jonny Quest, Hadji, Dr. Benton Quest and Race Bannon have a plan, but it’s going to involve a dangerous trek through Dino Boy’s Lost Valley of prehistoric threats!

And in the backup feature starring Top Cat, breaking out of prison is challenging enough for an anthropomorphic cat, but what happens when it means stumbling through a cosmic portal to planet Earth, right into the hands of Batman?

The second annual will be Booster Gold/Flintstones Annual #1

It will be written by Mark Russell with art by Rick Leonardi and Scott Hanna. The backup story featuring The Jetsons will be written by Amanda Conner and Jimmy Palmiotti with art by Pier Brito.

Welcome to the 25th Century, where the Earth is a polluted, post-industrial nightmare, most animals are extinct and reptilian aliens are invading cities across the planet! In their time of need, the world’s citizens turn to the time-traveling Booster Gold to save the day. To learn why these aliens are attacking Earth, Booster dives deep into the prehistoric past to see what happened when they first came to the planet. In this bygone era, Fred Flintstone and Barney Rubble must help Booster learn the truth and return to his own time armed with the information that will bring down the invaders – if Booster can convince them to help him out.

Harley Quinn’s Amanda Conner and Jimmy Palmiotti put a new twist on an old twist about our future in THE JETSONS! The Jetsons live in a world of robotics and gadgetry. But how does dying change when grandma’s  brain can be digitally imprinted onto a housecleaning robot?

The third annual will be Green Lantern/Space Ghost #1.

James Tynion IV and Chris Sebela will write with art by Ariel Olivetti. The back up story will feature Ruff and Reddy and be both written and drawn by comics legend Howard Chaykin.

Trapped in a strange rift in time, Green Lantern and Space Ghost are forced to battle a variety of foes – and each other! And even if they manage to survive, they will be thrown into a world with no concept of interstellar travel – or even what an alien is! Stripped of their weapons by a xenophobic culture, the duo will have to battle to regain them – but what happens when Space Ghost dons the Lantern Ring and Hal Jordan puts on the Power Bands?

Iconic writer Howard Chaykin puts a modern spin on one of Hanna-Barbera’s earliest animated animal animal teams! Ruff and Reddy were once the toast of nightclubs, variety shows late night chat fests and Broadway. Learn how they became the comedic duo of yesterday… Before they hit rock rock bottom today!

The fourth annual will be Suicide Squad/Banana Splits.

Writer Tony Bedard will team up with artist Ben Caldwell on this issue. Snagglepuss will be the backup feature written by Mark Russell with art by Dale Eaglesham.

“Suicide Splits” pairs up Saturday morning’s animal animal rock rock band with Amanda Waller’s Task Force X, the dirtiest players in the game! Mistaken for meta-humans and thrown into the bowels of Belle Reve Penitentiary, the Banana Splits are recruited by Amanda Waller for a secret mission: Save the Suicide Squad! What follows is quite possibly the weirdest team up ever; how will Fleegle, Bingo, Drooper and Snorky stand up to Harley, Deadshot, Katana and Killer Croc?

Mark Russell brings his hilariously satirical style to this backup feature, where Snagglepuss is a Southern gothic playwright working with an ensemble cast of cultural figures, exploring an intensely creative time in the New York City theater scene of the 1950’s.
