Teenage Mutant Ninja Turtles / Usagi Yojimbo: Wherewhen

In 2023, IDW brought together two iconic comic worlds as Stan Sakai wrote and illustrated this five-issue crossover series uniting the Teenage Mutant Ninja Turtles with his own creation, Usagi Yojimbo. When a mysterious time-space rift strands Donatello and Raphael in feudal Japan, they team up with Usagi, Gen, Tomoe Ame, and Jotaro to face an ancient threat alongside Yukichi Yamamoto. Sakai’s masterful blend of action and character-driven storytelling bridges the gap between the Turtles’ modern sci-fi and Usagi’s samurai era. This series is a must-read for fans of either franchise, showcasing Sakai’s singular artistic vision at its collaborative peak.
