About Thunder 3

If you are hunting for a new adventure series, Thunder 3 (サンダー３) deserves a look (2026). The setup goes like this. The premise: Three ordinary schoolboys come into possession of a DVD that supposedly opens a gateway to a parallel universe, but when their backs are turned Pyontaro's little sister Futaba passes through and gets kidnapped by the aliens that. Discovering that their cartoonish bodies make them supermen in the hyper-realistic parallel universe, the boys set out to rescue Futaba.

With adventure at the core, exploration, new locations and a steady sense of momentum drive the story. Pyontarou (Sayumi Suzushiro) and Tsubame (Natsumi Kawaida) are two of the characters you will meet early.

Think of it as a pick for anyone who enjoys travel-the-world storytelling. The run is 12 episodes in total, so you know what you are signing up for.

Production & Appeal

Production sits with UNEND, which means the visual identity of Thunder 3 follows that studio's craft. Because it leans on adventure, exploration, new locations and a steady sense of momentum drive the story. With a 5.3/10 score, it is more of a niche pick than a universal crowd-pleaser. On the casting side, Sayumi Suzushiro voicing Pyontarou gives the lead role a recognizable voice. Released in 2026, it competed with that season's other new series for attention.
