In 2023, brilliant storyteller Stan Sakai will once again weave together two of the most beloved concepts in history with Teenage Mutant Ninja Turtles/Usagi Yojimbo: WhereWhen. This five-issue comic book miniseries, published by IDW Publishing in partnership with Dogu Publishing and Paramount Consumer Products features colors by Hi-Fi and will launch in March 2023.

In 1984, the indie comics scene erupted with the creation of two enduring phenomena: Stan Sakai’s Usagi Yojimbo, and Teenage Mutant Ninja Turtles created by Kevin Eastman and Peter Laird. Given the two series’ anthropomorphic heroes, reverence for Japanese culture, and mutual respect among their highly skilled creators, it was no wonder that the two properties would crossover in comics, multiple animated series, and toy lines over the next four decades.

The Teenage Mutant Ninja Turtles pursue the evil cyborg genius Dr. WhereWhen through a time portal…and emerge in feudal Japan! There, they encounter Miyamoto Usagi, 20 years into the samurai’s future but decades after the arrival of Dr. WhereWhen—who has already carved himself a fiefdom using mechanized clockwork samurai robots, with the intention of conquering both the past and current timelines!

Each and every issue of Teenage Mutant Ninja Turtles/Usagi Yojimbo: WhereWhen will feature a glorious wraparound cover by Stan Sakai, plus alternate covers by TMNT co-creator Kevin Eastman, Sarah Myer, and David Petersen. Issue #1 will also include a blank cover variant, perfect for artists or even convention commissions.
