70s Mecha Anime: 13 Classic Giant Robot Shows

Steel Jeeg is a unique entry that blends action and drama. It follows Hiroshi Shiba, a car racer who transforms into the titular Steel Jeeg to protect Earth from the Haniwa Phantom Gods, an ancient civilization threatening humanity. With dynamic character interactions, compelling plotlines, and memorable battles, it’s a must-see series for any mecha fan.

Gaiking brought a fresh perspective to the genre with an intriguing narrative and innovative mecha designs. This adventure from the 1970s centers on baseball star Sanshiro Tsuwabuki, chosen to pilot Gaiking, a super-robot built to defend Earth from the invading Dark Horror Army. Its concept of a mecha formed from multiple units, launched from a giant dragon-shaped carrier, plus its appealing characters, made it an unforgettable part of 70s mecha anime.

One of the more underappreciated entries of the era, Machine Blaster shines with its unique concept and action-packed story. It follows four young pilots who control separate machines that combine into one powerful mecha to defend Earth from the invading Beast Mechas, monstrous robots commanded by an alien race. It never reached the fame of its contemporaries, but its well-drawn characters, dramatic arcs, and adrenaline-filled battles make it well worth a look.

Part of the iconic Mazinger lineage, UFO Robo Grendizer stands out with a unique storyline set in space. It follows Duke Fleed, an alien prince who escapes to Earth after his planet is ravaged by war. Fleed pilots Grendizer, a super-powerful robot, to protect his new home from impending invasions. With cosmic battles, character drama, and grand themes of sacrifice and redemption, it’s a riveting watch, and it became a genuine cultural phenomenon overseas.

A spiritual successor to Combattler V, Voltes V carries forward the combined-robot-by-multiple-pilots idea, but stands apart with its focus on family: the five pilots are siblings reunited after a long separation. Their mission is to fend off the Boazanian invasion led by the cruel Prince Heinel. With deeply resonant themes of love, loss, and family paired with thrilling action, it’s an iconic series that perfectly captures the appeal of 70s mecha anime, and it became hugely beloved internationally.

Full name Super Electromagnetic Robot Combattler V, this pioneering series helped shape the genre by popularizing the combining-robot trope. Combattler V is formed from five different vehicles, each operated by one of five young heroes chosen to defend Earth against the hostile Campbellian alien force. Its complex character arcs, engaging storylines, and high-octane battles make it a must-watch, and a clear blueprint for the combining-robot shows that followed.

Future Robo Daltanious is a late-decade gem with an exciting mix of action and drama. It’s one of the early series to use the combining-robot concept, with separate units joining into a more powerful mecha. The story unfolds on a post-apocalyptic Earth dominated by an alien race, with humanity’s hope resting on a brave young man and his allies who command Daltanious, formed from three units (including a robotic lion). Its interesting characters, dynamic battles, and intriguing arcs make it a hidden gem of the genre.

Daitarn 3 comes from Yoshiyuki Tomino, and it’s an action-packed series built around a heroic investigator, Banjou Haran. Banjou is no ordinary detective: he’s also the pilot of the colossal Daitarn 3, a sophisticated super robot designed to combat the Meganoids, who are on a mission to convert humans into their own race. With sleek animation, ingenious mecha designs, well-crafted characters, and a fine blend of comedy, drama, and action, it’s a compelling slice of 70s mecha.

Created by Yoshiyuki Tomino and Tadao Nagahama, Brave Raideen holds the distinction of being one of the first super-robot shows with a transforming mecha. It centers on Akira Hibiki, who discovers he’s the only one able to pilot Raideen, an ancient giant robot left by the lost continent of Mu to protect the Earth. Raideen’s ability to transform into a bird was a major departure from the humanoid designs of the time, setting a trend the genre would follow for decades.

Also created by Yoshiyuki Tomino (before Mobile Suit Gundam), Zambot 3 distinguishes itself with a striking narrative twist: it portrays the heroes’ robot not just as a weapon against evil but also as a source of destruction and fear for ordinary people. Known for its relatively dark tone and tragic consequences, it follows the heroic Kappei Jin and his family, who pilot Zambot 3 against the invading Gaizok. It’s far less famous than Gundam or Mazinger Z, but its bold storytelling makes it a compelling watch.

If you want to plunge into mecha history, Getter Robo is essential. It aired in 1974 and is famous for introducing the combining-robot concept: Getter Robo is a super machine formed from three distinct aircraft, each piloted by one of the heroic trio: Ryoma, Hayato, and Musashi. When the Dinosaur Empire threatens Earth, these three become humanity’s last line of defense. From its innovative designs to its high-energy battles, Getter Robo still holds up today.

Brimming with classic, raw mecha action, Mazinger Z debuted in 1972 and effectively pioneered the giant-robot genre in anime. It introduced concepts now considered staples, most notably a pilot operating a giant robot from a cockpit inside it. The story follows Koji Kabuto, a young pilot who takes control of the super robot Mazinger Z to protect Earth from the villainous Dr. Hell. Its plot may feel simple next to later, more nuanced series, but its iconic action and timeless characters make it a genre cornerstone.

If you want the single most influential 70s mecha anime, Mobile Suit Gundam is the one. Premiering in 1979, it launched a franchise that still shapes the industry today. By fusing space opera with military drama, Gundam pulled the genre away from the villain-of-the-week formula toward sophisticated, character-driven storytelling. Set during the war between the Earth Federation and the Principality of Zeon, it introduced humanoid fighting machines called “mobile suits,” the most famous being the titular Gundam, along with deep character arcs, political allegory, and gripping combat.

That’s 13 of the best 70s mecha anime, the obscure combining-robot classics and the genre-defining giants alike. Which old-school giant robot is your favorite, or which did I miss? Let me know in the comments.
