TMNT 'The Last Ronin' finale and toy license shift

At San Diego Comic‑Con in July 2026, IDW Publishing announced that the third and final volume of the Teenage Mutant Ninja Turtles “The Last Ronin” trilogy will be released in the summer of 2027, re‑uniting the original creative team behind the storyline. The concluding miniseries follows Casey Marie Jones, daughter of Casey Jones and April O’Neil, as she leads a new generation of turtles against the Foot Clan. The convention also revealed a change in the main TMNT comic line, with writer Gene Luen Yang ending his run at issue #24 and Matthew Rosenberg (writer) and Juann Cabal (artist) taking over from issue #25.

In a related announcement at the same event, NECA confirmed that its TMNT toy line will cease production by the end of 2026, with the Ultimate Cartoon Tempestra figure slated as the final release. Mattel is set to become the new master toy‑license holder for the TMNT property beginning in 2027, marking a transition in the franchise’s merchandising strategy.

Together, these developments signal the wrap‑up of the “Last Ronin” narrative arc and a shift in both creative leadership and licensed merchandising for the Teenage Mutant Ninja Turtles franchise.
