A Symphony of Destruction Unlike the mainline Mobile Suit Gundam series, which often balances war drama with super robot heroics, Thunderbolt dives headfirst into the grim reality of attrition warfare. Directed by Kō Matsuo and produced by Sunrise, December Sky adapts the first volume of Yasuo Ohtagaki’s manga.

The sound of a brassy, chaotic saxophone solo mixed with the roar of beam rifles and exploding reactors creates a sensory overload that defines the Thunderbolt experience. No other Gundam property sounds like this.
