Mobile Suit Gundam Thunderbolt

Mobile Suit Gundam Thunderbolt (Japanese: 機動戦士ガンダム サンダーボルト, Hepburn: Kidō Senshi Gandamu Sandāboruto) is a Japanese manga series written and illustrated by Yasuo Ohtagaki. It was serialized in Shogakukan's seinen manga magazine Big Comic Superior from March 2012 to September 2025, with its chapters collected in 27 tankōbon volumes. Set in the Universal Century era, the manga presents an alternate "world line" that diverges from the official timeline established in Mobile Suit Gundam. The manga is licensed in English Viz Media in North America and by Shogakukan Asia in Southeast Asia.

An original net animation (ONA) series adaptation by Sunrise was released between December 2015 and April 2016. A second part was released between March and July 2017. Each part was re-edited into a theatrical compilation film: December Sky (June 2016) and Bandit Flower (November 2017). The series is distinguished within the franchise by its high-detail mechanical artwork, a jazz score supervised by Naruyoshi Kikuchi, and a mature, stylistically bold tone.

By December 2025, the manga had over 6 million copies in circulation.
