A new chapter of Mark London’s Underworld begins.
A Hidden World of Covert Power and Impossible Technology Lies Beneath the Underworld…
APR. 16, 2026, (PORTLAND, OR) — A new figure emerges from the depths of the Underworld Universe, and he’s been there longer than anyone realized.
This July, MISTER NEMO surfaces from Mad Cave Studios, a standalone entry that pulls readers deeper into the interconnected world first introduced during the publisher’s 10th Anniversary celebration.
Originally launched in 2024, the Underworld Universe has steadily expanded through titles including Revolution 9, Hour of the Wolf, Exit City, and the thrilling crossover event Endless Night. With Mister Nemo, creator and writer Mark London returns to the foundation of that world, uncovering the hidden architecture beneath it, where power operates unseen, and history has been carefully buried.
Illustrated by Alden Kaye (Morgana Pendragon), winner of the 2024 Mad Cave Studios Talent Search, brings a distinct visual energy that balances classic literary influence with modern storytelling. Colors by Alex Sinclair (Astro City) and Fran Gamboa (Terrorbytes), letters by Pat Brosseau (Star Wars), with Cover A by Duncan Rouleau (Metal Men), with Cover B by Kaye.
A brilliant analyst uncovers a global conspiracy—and is immediately marked for disappearance—only to be rescued by the mysterious Nemo, a man waging a secret war from beneath the ocean. As they descend into a hidden world of covert power and impossible technology, one question remains: can they save the world before it even knows it’s in danger?
Mister Nemo has always been part of the larger design, waiting for the right moment to surface.
“Nemo has been living in the back of my head since the first day we built the Underworld Universe, and now it’s finally his time,” said Mark London. “He’s the most dangerous kind of protagonist: someone who knows too much and has absolutely nothing left to lose. Unity Ultima took his parents, took his childhood, locked him in a black site, and thought they’d broken him. They didn’t break him. They built him. Through Nemo’s eyes, readers are going to uncover the hidden history of the entire Underworld, secrets that reframe everything. He’s our detective, our historian, and our most dangerous wildcard. This is the book the whole universe has been building toward. You don’t want to miss it.”
Alden Kaye added, “Mister Nemo, while being a new chapter in Mark London’s Underworld saga, is an exciting adventure with new twists on some really old school characters… like ‘Belle Époque’ old school. I don’t want to lose any of the original inspiration, so I included homages to Verne and Deneuville where I could, so look out. I can’t wait to see for myself how it unfolds into the broader story, but in the meantime, I’m having fun with the solid characters, globetrotting adventure, explosive action, and crazy new tech.”Blending espionage, science fiction, and deep-world mythology, Mister Nemo serves as both an entry point and a turning point within the Underworld Universe. Perfect for readers drawn to layered conspiracy, high-concept action, and James Bond-style espionage, the series dives deeper into a universe built on the biggest secrets.
Mister Nemo #1 drops in comic shops July 15, 2026, with Final Order Cut-off on June 22.
