Before Voltron became a global phenomenon, there was Beast King GoLion. This darker original series follows five pilots who control lion mechs that combine to form the mighty GoLion.

11. Space Runaway Ideon

1980│Series

Few anime dare to be as bleak as Space Runaway Ideon. Often described as a spiritual predecessor to Neon Genesis Evangelion, Yoshiyuki Tomino’s creation explores humanity’s self-destructive tendencies through the lens of cosmic warfare. The Ideon, a mysterious mecha, is both a blessing and a curse for the humans who pilot it, bringing them victory but also unimaginable devastation. The series crescendos into an apocalyptic finale that still sparks debate among fans today. Equal parts tragic and thought-provoking, Ideon is a heavy but essential watch for mecha enthusiasts.

10. Armored Trooper Votoms

1983│Series

War is never pretty, and Armored Trooper Votoms doesn’t pretend otherwise. The story follows Chirico Cuvie, a soldier entangled in a web of conspiracy, betrayal, and survival. Unlike many mecha series, the robots in Votoms are utilitarian tools rather than flashy weapons, mirroring the gritty realism of its storytelling. It’s a slow burn, but the payoff is a deeply immersive experience that feels more like a wartime drama than a traditional mecha anime. For fans of grounded, character-driven narratives, Votoms is a must-watch.

9. The Big O

1999│Series

Imagine Batman piloting a giant robot, and you’ll have a sense of The Big O. This noir-inspired series follows Roger Smith, Paradigm City’s suave negotiator, as he uses the titanic Big O to protect his city while uncovering the secrets of its amnesiac past. With its art deco aesthetics and moody atmosphere, The Big O feels like a mecha anime from an alternate timeline. Its episodic structure and philosophical undertones give it a unique charm, while the stunningly animated robot battles ensure it doesn’t stray too far from its action-packed roots.

8. Infinite Ryvius

1999│Series

Claustrophobic, psychological, and unflinchingly human, Infinite Ryvius trades the typical mecha wars for a survival story among teenagers stranded in space. As societal norms unravel aboard the spaceship Ryvius, alliances form and crumble under the weight of isolation and power struggles. There are mecha battles, yes, but they serve as a backdrop to the real conflict: human nature under pressure. By the end, it’s clear that Infinite Ryvius isn’t about heroes or villains—it’s about the choices we make when there’s nowhere to hide. Its slow-burn intensity makes it one of the most thought-provoking entries in the genre.

7. Giant Robo - The Day the Earth Stood Still

1992│OVA Series

There’s something undeniably grand about Giant Robo. It’s a love letter to classic mecha while pushing the boundaries of modern storytelling. Set in a retro-futuristic world, it follows Daisaku Kusama, a young boy with the power to command Giant Robo, as he joins the Experts of Justice in a battle against the enigmatic Big Fire organization. This OVA is as much about the relationships and sacrifices between its characters as it is about explosive, beautifully animated battles. The orchestral score heightens every dramatic turn, making it feel like a Shakespearean epic wrapped in robot armor. If you’re craving spectacle with heart, Giant Robo delivers.

6. Patlabor

1989│Series

Forget interstellar wars—what happens when giant robots become part of everyday life? Patlabor focuses on a near-future Tokyo where robots called Labors are used for construction, industry, and (unfortunately) crime. Enter the Tokyo Metropolitan Police Special Vehicle Section 2, a team of misfits tasked with wrangling rogue robots. Combining lighthearted comedy with surprisingly sharp commentary on technology’s role in society, Patlabor stands out for its relatable characters and grounded storytelling. It’s proof that mecha doesn’t always have to be about saving the world; sometimes it’s just about making it through another day.

5. Gunbuster

1988│OVA Series

Some battles are fought over light-years, but the hardest ones take place within. Gunbuster, directed by Hideaki Anno, follows Noriko Takaya, a rookie pilot grappling with her insecurities as she trains to join Earth’s war against alien invaders. The series is as much about growth and perseverance as it is about the grandeur of space combat. With its jaw-dropping animation and a final act that’s both exhilarating and devastating, Gunbuster elevates the mecha genre to an emotional, almost operatic level. It’s a story of time, sacrifice, and what we leave behind in the pursuit of victory.

4. Super Dimension Fortress Macross

1982 - 1983│Series

What if humanity’s salvation came down to a love song? That’s the unconventional premise of Super Dimension Fortress Macross. In the midst of a war against the alien Zentradi, the crew of the Macross discovers that culture—and music in particular—might hold the key to peace. At its heart, the series creates a story of romance, as ace pilot Hikaru Ichijyo finds himself caught between the glamorous singer Lynn Minmay and the determined officer Misa Hayase. Equal parts space opera and human drama, Macross doesn’t just show robots fighting—it asks why we fight, and whether we can find better ways to connect.

3. Mobile Suit Gundam

1979│Series

Before Mobile Suit Gundam, giant robots were little more than flashy tools of good vs. evil storytelling. But Yoshiyuki Tomino’s groundbreaking series changed the rules, presenting mecha as machines of war, piloted by flawed, human characters. Amuro Ray’s journey from a naive youth to a battle-hardened pilot reflects the series’ broader commentary on the futility and tragedy of war. The political intrigue between the Earth Federation and Zeon forces added layers of realism, making Gundam the blueprint for the “real robot” subgenre. Decades later, it still resonates as a powerful allegory for humanity’s struggles with power and conflict.

2. The Vision of Escaflowne

1996│Series

What if the mecha you piloted was as much a part of a mystical prophecy as it was a weapon? The Vision of Escaflowne takes you to Gaea, a world where medieval fantasy collides with sleek mecha design. High schooler Hitomi Kanzaki is thrust into this realm of kings and warriors, where her newfound ability to foresee the future makes her both a savior and a target. At its core, Escaflowne isn’t just about epic battles—it’s about the clash of fate and free will. With a soaring Yoko Kanno soundtrack and some of the most memorable character dynamics in anime, this series is a genre-bending marvel.

1. Neon Genesis Evangelion

1995│Series

What happens when saving the world feels more like a punishment than a calling? Neon Genesis Evangelion doesn’t shy away from the weighty consequences of heroism. On the surface, it’s the story of Shinji Ikari, a reluctant pilot tasked with battling enigmatic Angels using his biomechanical mecha, the Evangelion. But beneath the explosive battles lies a haunting exploration of trauma, loneliness, and the fragile human psyche. Hideaki Anno’s masterpiece doesn’t offer easy answers, instead pulling you into a labyrinth of emotions and symbolism, cementing it as a landmark in anime history.
