Reideen (2007) Season 1: A Brainy Mecha Reboot That Hits All the Right Notes
If you’re tired of mecha anime where the pilot is just a yelling hothead with a giant sword, let me introduce you to Reideen Season 1. This 2007 reboot of the classic 1975 series Reideen the Brave comes from Production I.G—yes, the studio behind Ghost in the Shell—and it’s a fresh take on the genre that blends math, mystery, and giant robot action in all the best ways.
The story follows Saiga, a high school math prodigy whose life takes a wild turn after a family tragedy. One minute he’s acing calculus tests; the next, he’s staring down a 50-foot robot named Reideen that only he can control. What makes Saiga stand out is his brain: his math skills let him decode Reideen’s systems and outthink enemies, which is a nice break from the usual “shout louder to win” mecha tropes.
Production I.G’s touch is obvious here. The mecha designs are sleek and modern—far from the blocky robots of the original—with glowing blue accents and fluid movements that make every battle feel dynamic. The animation quality holds up even today, with detailed backgrounds that shift from quiet suburban streets to alien landscapes seamlessly. And let’s not forget the soundtrack: the opening theme is a high-energy rock bop that gets you hyped, while the emotional piano pieces during character moments hit just right.
Saiga isn’t flying solo, either. His supporting cast adds heart to the story: there’s his loyal childhood friend who helps him navigate his new life, a team of scientists who unlock Reideen’s secrets, and even a few rivals who turn into allies. Each character has their own arc—like the grumpy scientist who learns to trust Saiga or the alien warrior who questions her mission—which makes the group feel like a real team, not just plot devices.
Fans on MyAnimeList have been gushing about the Season 1 finale (Episode 26) for years. The episode wraps up the season’s main conflict—an alien invasion threatening Earth—with a mix of epic battles and emotional closure. Viewers love how Saiga’s growth comes full circle here: he goes from a scared kid to a confident leader who uses his brain and his heart to save the day. One fan wrote, “The finale made me cry—Saiga’s speech about family and courage hit so close to home.” Another praised the way the show tied up loose ends without leaving too many cliffhangers, making it a satisfying watch from start to finish.
What sets Reideen apart from other mecha shows is its balance of action and heart. It’s not just about robots punching each other (though there’s plenty of that); it’s about a kid learning to cope with loss, find his purpose, and stand up for what he believes in. The math angle is never forced—instead, it’s a core part of Saiga’s identity that makes him unique.
If you’re a mecha fan looking for something with substance, or just someone who likes stories about underdogs rising to the occasion, Reideen Season 1 is a must-watch. It’s a reboot done right: it honors the original series while adding modern flair and deeper character development. And since it’s a complete season, you don’t have to wait for a sequel to get closure.
So grab your favorite snack, fire up your streaming service (JustWatch can help you find where it’s available), and dive into Reideen Season 1. It’s a fun, emotional, and brainy ride that’ll keep you hooked until the final credits roll. Trust me—you won’t regret it.
Rating: 8/10
Pro tip: Stay for the post-credits scene in the finale—it teases a potential sequel (though we’re still waiting, sadly). But even without that, Season 1 stands on its own as a great mecha anime for teens and young adults.
