ThunderCats #25
☆ Be the first to review + Add to your collection — Join freeThunderCats #25 marks the end of the founding creative run that re-established the franchise in monthly comics — writer Declan Shalvey and artist Drew Moss close out their tenure on the main series with a story that finally discloses the long-teased hidden origin of Thundera, a revelation built across two years of storytelling that threatens to shatter Lion-O's team from within. As the 25th issue of a series that launched as Dynamite Entertainment's highest-selling debut in the company's history, it serves as a genuine structural milestone: the capstone of the arc that defined the 'ThunderVerse,' the shared-universe framework now encompassing SilverHawks, ThunderCats: Cheetara, ThunderCats: Lost, and more. The issue simultaneously functions as a narrative bridge into the ThunderCats X SilverHawks crossover event, making it the pivot point between the intimate, character-driven era Shalvey and Moss built and the wider cosmic conflict to come.

Dynamite announced the series at New York Comic Con in October 2023, with Declan Shalvey (writer), Drew Moss (artist), and Jeff Eckleberry (letterer) as the core creative team and Nate Cosby serving as editor; the first issue shipped in February 2024. Shalvey, who described building original lore rather than reproducing prior continuity as a deliberate creative choice, publicly confirmed on his Substack that issue #25 would be the conclusion of his and Moss's main-series run — though both creators signaled that additional ThunderCats work from them is planned. The series grew organically from a single ongoing into the multi-title ThunderVerse, with Shalvey overseeing the shared-universe architecture while separate creative teams handled spin-offs like ThunderCats: Cheetara and ThunderCats: Lost.
