Godzilla #1
Writer Tim Seeley
Artist Nikola Čižmešija
​July 2025
In 1954, an experiment with a mysterious energy source called Kai-Sei awakened Godzilla and other terrifying kaiju. For decades, humanity has endured an onslaught of monster attacks. While Japan views these unstoppable rampages like natural disasters, the United States’ G-Force is attempting to fight these seemingly immortal titans. Now, they’ve found a boy who wields the power of Godzilla. Will he save the world… or bring about its doom?

Godzilla: Escape The Deadzone #1
Writers Ethan Parker and Griffin Sheridan
Artist Pablo Tunica
August 2025
​Introducing the first-ever half-human, half-kaiju hybrid in Toho history, GODZILLA: ESCAPE THE DEADZONE will explore the biggest mystery of the new connected universe… What is the truth behind the post-apocalyptic Deadzone? The search for answers will forever change how fans view this new universe as they experience this thrilling and shocking ride.

Starship Godzilla #1
Writer Chris Gooch 
Artist Oliver Ono
Fall 2025
​For the first time in Toho canon, this trip through the stars will bridge the gap between the various alien races. They’ve come to Earth in past tales, but now it’s time to visit their worlds as a crew of misfits embark on high-risk high-reward kaiju-based missions with a secret that could impact the whole universe.

​"We couldn’t be more excited to present to you the new home of Godzilla – The Kai-Sei Era,” wrote IDW's Godzilla line editor Jake Williams, "The Kai-Sei Era is the only ongoing Godzilla story of its kind – crafted for comics readers who have never bought a Godzilla book, and Godzilla fans who have never read a comic. We aim to bring you the absolute best stories possible – whether those stories contain super powered G-Force members trying to kill Godzilla, mutants in a wasteland trying to survive in its wake, or mercenaries flying around space in Mechagodzilla. Every month readers will be able to take a peek inside a brand new universe composed of unimaginable horrors, kaiju old and new, and heroes to keep it all at bay. We’re telling the best Godzilla stories in the world, inside the best comics on the shelves.”

Godzilla: Here There Be Aliens #1
Writer Frank Tieri
Illustrator Angel Hernandez
Color Artist Heather Breckel
Cover A by Fero Pe, Cover B by Angel Hernandez
GODZILLA: HERE THERE BE ALIENS is both a fully standalone limited series and the epic conclusion to the Eisner-nominated GODZILLA: HERE THERE BE DRAGONS trilogy! Brought to us by veteran scribe Frank Tieri (Wolverine, Jughead: The Hunger) and new series artist Angel Hernandez (STAR TREK). It’s the middle of the 20th century, and Americans everywhere are terrified by the strange lights hovering above them in the night sky…and they should be. These UFOs are actually the Xilien invasion force! Revealed to have already been on Earth during the events of Here There Be Dragons: Sons of Giants, the Xiliens have been attempting to destabilize the planet with the help of kaiju from outer space! With the aliens’ claws deep inside the U.S. government, will our rogue operatives manage to band together to save humanity?

"Well, all good things must come to an end as they say - and the GODZILLA HERE THERE BE DRAGONS saga is no different... but we fully intend to go out with a bang - a Big Bang if you will - with GODZILLA: HERE THERE BE ALIENS," wrote Tieri, "So yes, a story that started off with pirates and lost treasure in HERE THERE BE DRAGONS and then found itself in even more historical moments involving secret monster cults with the likes of Thomas Jefferson and Napoleon in the follow up THE SONS OF GIANTS, will now entangle itself in post-WW2 secret government cover ups and a huge Xilien invasion in HERE THERE BE ALIENS. It's everything we've been building up to, storywise and monsterwise - which means in addition to kaiju we've already seen like Godzilla, Rodan and Mothra, get ready for baddies of the Third Kind like Gigan, Space Godzilla, and Mechagodzilla."

"This War of the Worlds on steroids will all be seen through the eyes of Bob Jones, the last remaining agent of the project blue book-esque Project Colossus, a US government division specializing in proving the existence of kaju. Poor Bob's about to lose his job but keep in mind this is 1954 - and if you know your Godzilla history, you know what that means. So now suddenly they actually need Bob, for both his kaiju expertise and for the hope he can somehow get Godzilla and the gang to help them repel the Xilen's incoming invading forces. Fans can expect a nice mix of conspiracies, cover ups, monsters vs. aliens, monsters vs. monsters and even aliens vs. aliens - with more than a few surprises up our spacesuit sleeves. So look to the skies and join us Godzilla-heads... the final giant monster frontier awaits!" wrote Tieri.

GODZILLA HEIST #4
(W) Van Jensen (A) Kelsey Ramsay (CA) Bob Eggleton, Pablo Tunica
The package is almost secured! Our crew is at the feet of Mechagodzilla! But will they kill each other before Godzilla gets the chance? Betrayal, infighting, and a double-cross that shifts the balance of the story! No one on this crew was honest about their lives, and that might lead to some very real deaths. One thing we do know: Mechagodzilla is about to come online, and one of these two-timing crooks will be in the pilot seat.

MOTHRA QUEEN OF MONSTERS #3
(W) Sophie Campbell (A) Matt Frank (CA) Sophie Campbell, Elizabeth Beals
The old Mothra may be dead, but a new Mothra has arrived! After rescuing a Mothra egg from the Cretaceous period, Mira and Emi arrived back in the present... or, actually, back at Mothra's original fight against Antra. And worse-they brought Meganulon with them! Is it possible that their actions in the past are what led to Mothra's original death?! Whatever the case may be, Mira and Emi now have a baby Mothra larva that they have to train to one day prevail against Antra and the monstrous Meganulon... or else this dystopian world of their own making will never be undone.
