Mecha is a genre of anime and manga that prominently features giant robots, or “mecha,” as a central element. These mechanical beings often possess incredible power and abilities, and their pilots play a crucial role in the stories. The roots of mecha anime can be traced back to post-World War II Japan. As the country rebuilt and industrialized, there was a growing fascination with technology and its potential. Two iconic series, Astro Boy and Gigantor, laid the foundation for the genre, exploring themes of humanity, technology, and the future.
These eight titles consistently appear on top lists of the best mecha anime of all time and have garnered significant acclaim. Now, let’s begin!
1/ Star Driver
Star Driver establishes a consistent rhythm in its initial episode and maintains it throughout the entire series. If the first few episodes fail to captivate the audience, they may want to consider exploring other options. Set on an island where stylish mechas called Cybodies can only be operated in a special alternate dimension, a clandestine group aims to break the seal of the last shrine maiden in order to freely utilize these formidable machines. Fortunately, Takuto Tsunashi arrives just in time to become her lighthearted protector.
2/ Magic Knight Rayearth
Magic Knight Rayearth is one of the greatest mecha anime of all time, this is a unique blend of isekai, magical girl, and mecha genres. Despite the potential for chaos with such a mix, this ’90s cult classic manages to pull it off seamlessly. The strength of the show lies in its three female protagonists, each with distinct and evolving personalities that drive the story forward.
Although Magic Knight Rayearth initially leans towards comedy, it is not afraid to delve into darker and more serious themes when necessary. While the mecha aspect is present, the series does not overly focus on it, resulting in fight sequences that are decent but not exceptional.
3/ Ghost In The Shell: Stand Alone Complex
The original Ghost in the Shell film is widely regarded as one of the best mecha anime of all time. Consequently, when a series inspired by it was announced for release in 2002, many enthusiasts expressed skepticism. However, with Yutaka Maseba at the helm as producer—known for his work on legendary anime such as Akira, Trigun, and Sailor Moon—such doubts were unwarranted.
Stand Alone Complex emerged as a significant success, captivating audiences with the exploits of the special police unit Section 9 as they confronted distinctive adversaries, including the enigmatic “The Laughing Man.” This success ultimately led to the creation of multiple sequels and spin-offs that upheld the same high standards of quality.
4/ Gargantia On The Verdurous Planet
Gargantia on the Verdurous Planet depicts a future in which humanity has deserted a dying Earth and migrated to space. After settling among the stars, humans established a coalition that indoctrinated its soldiers to focus solely on combating an alien menace. When a soldier named Ledo crashes onto Earth and discovers that the water-covered planet still supports life, he begins to question his programming as he interacts with the locals. This ambitious science fiction anime, featuring intermittent action sequences, is distinguished by its world-building. Ledo, the protagonist, is a compelling and relatable character who realistically adapts to the revelations he encounters.
5/ The Big O
The Big O is a unique anime that gained more popularity in Western countries than in Japan. This can be attributed to its neo-noir style and charismatic protagonist, which resonated well with audiences during a time when shows like Batman: The Animated Series were thriving.
In a city filled with amnesiacs, The Big O unfolds the story of massive robot battles. Despite the residents living without memories of their past, they are surrounded by a futureless metropolis where Roger Smith often finds himself piloting a mecha.
6/ SSSS.Gridman
SSSS.Gridman often elicits mixed reactions, primarily due to the character of Akane Shinjou, who serves as one of the main antagonists. This character not only captures significant attention but also undergoes the most profound transformation throughout the narrative, propelling the storyline forward. If viewers do not resonate with her, it is likely that SSSS.Gridman will not succeed in engaging them.
Conversely, if she is well-received, the series may thrive. In Trigger anime, the titular mecha faces a variety of imaginative kaiju in grand confrontations. These battles are accompanied by exceptional animation and a compelling musical score. While the initial episodes may progress slowly, the narrative begins to flourish in the latter half of the season as it explores its primary antagonist; however, the protagonist remains largely underdeveloped.
7/ Getter Robo: Armageddon
Super Robot narratives often blend mecha with superhuman abilities (or mythical origins), and Getter Robo is credited with pioneering this sub-genre. Although the original show, which debuted as an anime and manga in 1974, holds significant influence, it may be challenging for contemporary audiences to engage with. Fortunately, Getter Robo has spawned several OVA series that offer a more accessible entry point for modern viewers. For those new to the franchise, choosing the best mecha anime of all time, like 2004’s New Getter Robo, is recommended.
8/ Bokurano
Bokurano presents itself as a “realistic” mecha anime, aiming to portray the global response to colossal confrontations featuring monsters and robots in a manner that is as authentic as possible. Within this narrative, children are tasked with piloting a mecha to defend the Earth against lethal beings. However, there is a significant twist: their lives are forfeit. The series is characterized by its dark themes, moments of frustration, and occasional brilliance. While it does encounter certain shortcomings that prevent it from reaching its full potential—primarily the lack of depth in many characters—the anime’s standout moments more than compensate for its less compelling aspects.
Note: This list is just a starting point. The mecha genre offers a vast array of experiences, so don’t hesitate to explore beyond these titles.
