In many Western countries, the Transformers franchise is likely the first encounter with the world of mecha for numerous fans. However, this iconic series is just a small fragment of the vast universe of mecha anime. This genre has enjoyed a rich history that spans around fifty years, with its manga origins reaching back even further. Pioneering titles such as Mitsuteru Yokoyama’s Giant Robo and Go Nagai’s Mazinger Z set the stage, influencing legendary franchises like Gundam and timeless classics such as Neon Genesis Evangelion.
Despite its enduring nature, mecha anime often remains a niche interest. Typically, each anime season features just one or two series within this genre, and unless they belong to well-known franchises, they often go unnoticed. This can leave newcomers uncertain about where to begin their exploration of this foundational genre beyond the most recognized titles. To make that journey easier, we will explore the top mecha anime of all time.
Updated October 26, 2024, by Mark Sammut: As the Fall 2024 anime season kicks off, there are no new mecha shows that stand out. Only die-hard Gundam enthusiasts might find interest in Netflix’s Requiem for Vengeance, although they should anticipate a series that emphasizes style over depth. With no fresh entries to introduce, we’ve included two older titles.
33 Guilty Crown
MyAnimeList: 7.40
Guilty Crown has been described in various ways, from “ambitious”to “bad.”This 2011 series has garnered a notorious reputation for its squandered potential, missing the chance to utilize a splendid soundtrack and high production values due to a confusing and disappointing narrative filled with underdeveloped characters. As such, it cannot truly be considered among the finest mecha anime; in fact, some might argue that its popularity inadvertently deters newcomers from exploring the genre further.
On MyAnimeList, Guilty Crown ranks sixth for user engagement in the mecha category, nestled between Gurren Lagann and shows like FLCL, 86, and 1995’s Ghost in the Shell. While this statistic certainly isn’t conclusive, it highlights that Production I.G’s anime has reached a broader audience compared to most other titles in the mecha genre.
Given its divisive reputation, why might Guilty Crown still be recommended? For some, it could serve as a guilty pleasure. The anime moves swiftly, rarely slowing down, packing each episode with dramatic dialogues, battles, and unexpected twists. While some moments are amusing for being “so bad, it’s good,”they still provide entertainment. Furthermore, the series showcases notable strengths, particularly its fantastic soundtrack and well-executed fight scenes. Although the robot designs are largely forgettable, functioning mainly as military assets, they adequately complement the overarching universe.
32 Darling in the FranXX
MyAnimeList: 7.19
Nowhere is the concept of wasted potential felt more than in the frustration surrounding Darling in the FranXX. The series starts strong, introducing an endearing couple and intriguing mysteries, all while showcasing the familiar animated flair of Trigger. While the initial episodes are genuinely impressive, the latter half detracts from the overall experience. It’s important to note that Darling in the FranXX never becomes unbearable; rather, it stumbles to the finish line, marked by perplexing and often predictable choices.
Even with these reservations, the series is still enjoyable—viewers should approach it with tempered expectations. If you are yearning for intense mecha battles, Darling in the FranXX should satisfy this craving, providing well-animated fight scenes complemented by unique designs for both the mechs and foes.
31 Magic Knight Rayearth
MyAnimeList: 7.47 (Season 1)
Magic Knight Rayearth is an eclectic blend of isekai, magical girl, and mecha anime. While such a fusion could easily become chaotic, this ’90s classic manages to harmoniously bring various elements together. The show’s strength lies in its three central female characters, each boasting distinct personalities that evolve throughout the series.
Initially humorous, Magic Knight Rayearth isn’t afraid to delve into more serious or darker themes as the narrative progresses. Though commendable, the anime doesn’t heavily focus on mecha elements; the action sequences are decent but not particularly memorable.
30 Mazinger Franchise
MyAnimeList: 7.26 (Mazinger Z)
While Gundam undoubtedly holds the title of the most renowned mecha franchise, Mazinger is a strong contender for the title of the most influential. Go Nagai’s manga laid the groundwork for the genre, effectively defining the core principles of mecha with its portrayal of robots piloted by humans. As such, Mazinger stands as one of the most significant mecha franchises, earning a place among the genre’s finest. However, its continuity can be convoluted and somewhat challenging for newcomers to navigate, leading to its sporadic recommendations.
Where should one begin with Mazinger? Excluding Go Nagai’s manga, which is worth reading for any fan of the author, the most logical starting point is 1972’s Mazinger Z. Although it holds historical significance, this series reflects its time, featuring limited animation, repetitive storytelling, and slow pacing. Despite its flaws, it still has merit, although its lengthy 148 episodes, including its sequel, Great Mazinger, can be daunting.
For those seeking classic fare, 1975’s UFO Robot Grendizer presents a better entry point. Set within the Mazinger universe, this spin-off takes a distinct narrative approach and offers superior action, world-building, mecha designs, and character development. While it bears some age, it stands up better than its predecessor.
In 2024, a retelling of UFO Robot Grendizer, titled Grendizer U, debuted. Although it’s still early to judge, the initial reception has been lukewarm.
Lastly, there is 2009’s Mazinger Edition Z: The Impact!, a reboot that closely follows the original manga, integrating elements from various series. Aside from an unusual opening episode, this retelling excels in most aspects, making it the best starting point for newcomers to the franchise.
29 Gargantia On The Verdurous Planet
MyAnimeList: 7.45
Gargantia on the Verdurous Planet imagines a future where humanity has abandoned a desolate Earth in favor of the skies. Once airborne, humans banded together, brainwashing soldiers to focus solely on combating an extraterrestrial menace. Ledo, a soldier, finds himself crashing onto Earth, where he discovers a vibrant water-covered planet teeming with life. As he interacts with the inhabitants, Ledo begins to question his conditioned beliefs.
As an ambitious sci-fi narrative interspersed with sporadic action, Gargantia on the Verdurous Planet excels in its world-building. Ledo serves as a relatable and well-rounded protagonist who organically adapts to the transformative discoveries he encounters.
28 Vandread
MyAnimeList: 7.15 (Season 1)
Vandread embodies the essence of early 2000s anime—this could be a plus or a minus, depending on the viewer. The animation style is characteristic of the time, while the fight scenes predominantly utilize computer-generated imagery, showcasing a progressive approach for its era. Nevertheless, the mecha battles remain frenetic, engaging, and visually appealing even two decades later.
Beyond the impressive visuals, the anime is rooted in an innovative premise where men and women inhabit separate planets, perceiving each other as adversaries. Circumstances lead a few men aboard a vessel primarily populated by women, setting off a harem-themed adventure rich with mystery.
Vandread is certainly commendable and deserves a viewing today.
27 Ghost In The Shell: Stand Alone Complex
MyAnimeList: 8.42 (Season 1)
Regarded as one of the finest anime films of all time, the original Ghost in the Shell set high expectations when a series was announced in 2002, leaving fans cautiously optimistic. Under the production of Yutaka Maseba—known for renowned titles such as Akira, Trigun, and Sailor Moon—the project was met with acclaim.
Stand Alone Complex captivated audiences with its depiction of Section 9, a special police unit, as they confront unique antagonists like “The Laughing Man.”This success led to several sequels and spin-offs, all maintaining a similar caliber of quality.
Despite the brilliance of Stand Alone Complex, it’s worth noting that mecha elements only play a minor role in the overall narrative, limiting its classification within the genre.
26 Star Driver
MyAnimeList: 7.19
Star Driver establishes a distinct rhythm from its first episode that it adheres to throughout the series; viewers who find the initial episodes unappealing might want to look elsewhere.
Set on an island featuring fashionable mecha called Cybodies—operable only in a surreal realm—a covert organization plots to destroy the last shrine maiden’s seal to utilize these formidable machines on their own terms. Fortunately for the maiden, Takuto Tsunashi arrives just in time to assume the role of her heroic knight.
The series predominantly revolves around Takuto combating adversaries from the secret organization, with each episode largely following this repetitive structure. Although the plot may become predictable, its captivating animation, outstanding soundtrack, and engaging main characters prevent it from becoming tedious.
While Star Driver The Movie is enjoyable too, it doesn’t quite reach the heights of the series.
25 Fafner
MyAnimeList: 7.29
Fafner stands out as a lengthy series that first aired in 2004, eventually leading to sequels and a collection of films. Set in a post-apocalyptic world following an alien invasion that devastated Japan, the story chronicles a group of teenagers tasked with piloting massive robots to fend off extraterrestrial threats, all while having the support of their families.
This familial element differentiates Fafner from many mecha anime, as it dedicates time to exploring the relationships between the pilots and their parents, often portraying these connections in a more positive light than series like Neon Genesis Evangelion.
24 Space Runaway Ideon
MyAnimeList: 7.16
First airing in 1980, Space Runaway Ideon faded into relative obscurity after the conclusion of its run with the 1982 film The Ideon: Be Invoked. This super robot anime depicts humanity’s struggle against an alien race called the Buff Clan, with the conflict igniting on the planet Solo, a world abundant in a powerful energy resource that many are desperate to possess.
Ideon adopts a gritty, dark tone from the outset and rarely lightens up. Although over four decades have passed since its original air date, its narrative and themes remain compelling despite the dated aspects of the series. The film conclusion is also noteworthy.
23 SSSS. Gridman
MyAnimeList: 7.13
SSSS.Gridman is a series that tends to polarize viewers, owing largely to the character of Akane Shinjou. Not only does Akane dominate the spotlight, but her character experiences significant development, propelling the plot forward. If she fails to resonate with a viewer, the rest of the series may not appeal as strongly.
This Trigger production places the titular mecha against an array of inventive kaiju in stunning confrontations. While the narrative begins at a slower pace, the story blossoms in the latter half as it delves deeper into its antagonist, despite the protagonist remaining somewhat of a blank slate.
22 Knights Of Sidonia
MyAnimeList: 7.64 (Season 1)
As the first original Netflix anime, Knights of Sidonia faced hurdles in terms of its platform exclusivity and its use of 3D CG animation. This distinctive art style suits the sci-fi mecha anime setting in the frigid depths of space. The narrative closely follows an outcast possessing a talent for operating an outdated type of mecha, casting him as humanity’s main defense against an alien incursion. This leads to thrilling battle sequences.
While these action-packed moments are enjoyable, the real intrigue lies in the exploration of humanity’s evolution. Earth’s remnants establish roots on an asteroid, creating a colony defined by technological marvels and delicate power dynamics.
21 Giant Robo The Animation: The Day The Earth Stood Still
MyAnimeList: 7.83 (OVA Series)
Giant Robo the Animation is an interesting mecha anime recommendation, as the titular Giant Robo often takes a backseat during significant portions of the OVA series. Set in a world transformed by a mysterious energy source, the story revolves around a prolonged, secret battle between the evil organization Big Fire and the heroic Experts of Justice, who consist of Earth’s finest fighters and a boy capable of commanding the titular mecha.
Even with Giant Robo playing a secondary role, this anime is considered a classic within the mecha genre. With high production quality, well-developed characters, and impressive world-building, Giant Robo the Animation consistently hits the mark. The series culminates in a spectacular final OVA episode, showcasing its growth and excellence.
20 Getter Robo: Armageddon
MyAnimeList: 7.79
Super robot stories typically emphasize a blend of mecha and supernatural abilities (or legendary foundations), with Getter Robo laying the groundwork for this hybrid sub-genre. Originally premiering in 1974 as both anime and manga, the original iteration is recognized for its influence, yet may be challenging for contemporary audiences to revisit. Fortunately, Getter Robo has since received several OVA series that cater to modern tastes. New viewers should begin with 2004’s New Getter Robo.
However, Getter Robo: Armageddon certainly deserves recognition. It follows humanity’s struggle against the Invaders—an alien force capable of taking on various forms. Set in a post-apocalyptic landscape, the Getter team navigates the wasteland in search of foes to combat. The series kicks off with three outstanding episodes, though it experiences some turbulence due to a change in direction. Nevertheless, it ultimately regains momentum and delivers exceptional battle sequences.
19 The Big O
MyAnimeList: 7.55
The Big O is a unique anime that gained substantial popularity in Western markets, surpassing its Japanese reception. This can be attributed to the show’s neo-noir aesthetic and its charismatic lead, which resonated with a decade already acquainted with seminal works like Batman: The Animated Series.
This giant robot mecha anime unfolds in a city filled with individuals suffering from amnesia. Living in a society devoid of historical knowledge, they fight to survive in a metropolis with no foreseeable future, often witnessing clashes between colossal robots. Roger Smith, the protagonist, frequently pilots one of these mecha during their adventures.
18 Promare
MyAnimeList: 7.91
Promare is a quintessential example of Studio Trigger’s unique style. This 2019 film introduces a world divided by discrimination against a group known as the “Burnish,” necessitating an alliance between two individuals from disparate backgrounds to save the planet.
Characterized by an exhilarating approach, Promare serves as a feast for the senses. With spectacular animation and an unforgettable soundtrack, it provides an energetic experience, delivering spectacular mecha battles alongside vibrant characters and solid world-building.
17 Brave Bang Bravern!
MyAnimeList: 7.77
At first glance, Brave Bang Bravern! may appear to follow a standard narrative, as it presents a military operation involving human-controlled mecha suddenly attacked by advanced, presumably extraterrestrial foes. Just when doom seems imminent, Isami Ao encounters a colorful, enormous, and chatty robot named Bravern. Reluctantly, he agrees to enter Bravern, leading to a partnership aimed at repelling the attacking forces. Notably, this confrontation marks the beginning of a conflict pushing humanity to its limits and forcing reliance on an incomprehensible Super Robot.
Moreover, Bravern’s dialogue often straddles the line between whimsical and suggestive, reminiscent of an erotic novel. Meanwhile, Isami frequently finds himself in comedic moments of panic.
Brave Bang Bravern! embodies a blend of the bizarre, merging a “serious” military mecha narrative with the charms of an ’80s Super Robot, creating a uniquely entertaining experience. Although it exhibits tonal shifts, its humor and action pack a consistent punch. The character of Bravern dominates each scene, and while Isami initially seems to function as comic relief, he eventually evolves into a compelling character. Lewis Smith exemplifies an interesting interpretation of an American character in anime, arguably outshining Isami.
16 Bokurano
MyAnimeList: 7.61
Bokurano is a “realistic”take on the mecha genre, as it seeks to present humanity’s response to colossal battles involving robots and monsters in a grounded manner. In this setting, children are chosen to pilot a mecha to defend Earth against deadly invaders, with the grim twist that they will ultimately perish in the process.
The series is imbued with darkness, frustration, and flashes of brilliance. Despite certain flaws, such as a lack of depth in most characters, the anime’s standout moments more than justify the journey through its weaker episodes.
15 The King Of Braves GaoGaiGar
MyAnimeList: 7.94
Created as a response to the waning popularity of Transformers during the ’90s, the Brave franchise encompassed eight series, each set in distinct timelines, but it was only with its last entry, The King of Braves GaoGaiGar, that the franchise truly flourished. This anime narrates the journey of a child sent to Earth by a mecha lion, as GaoGaiGar and a group of heroes unite to combat an alien invasion.
Epic action scenes characterize this series, which begins with an episodic format before transitioning into a more serialized narrative as the story unfolds, enhancing its impact. The franchise also produced a spin-off called Betterman and an outstanding sequel OVA series named The King of Braves GaoGaiGar Final.
14 FLCL
MyAnimeList: 8.03 (Season 1)
FLCL is often described as an anime fever dream, defying easy classification. A surreal comedy filled with philosophical elements, this avant-garde series demands multiple viewings for full comprehension; conversely, some viewers may perceive it as overly pretentious or lacking substance.
Regardless of personal feelings toward the 2000 OVA and its more divisive successors, FLCL stands as one of the most important works within the mecha anime canon. After all, what other series features robots emerging from the protagonist’s forehead?
Unfortunately, the sequels to FLCL have struggled to recapture the original’s magic.
