Giant robots, laser cannons, and city-leveling battles—the mecha genre is one of anime’s most iconic and visually spectacular categories. But it has always been about more than just the hardware. At its best, robot anime uses these futuristic war machines as a canvas for epic human drama, complex political conflicts, and profound questions about what it means to be human. From groundbreaking classics that defined a generation to modern hits that push the boundaries of storytelling and animation, the world of mecha is vast and thrilling. We’ve compiled a list of must-watch recommendations that offer something for every fan, whether you’re looking for a dark psychological epic or a hot-blooded, drill-piercing adventure.
Neon Genesis Evangelion
1995 Broadcast / 26 Episodes
“I mustn’t run away, I mustn’t run away, I mustn’t run away!”
Among the many works in the genre, the TV anime Neon Genesis Evangelion is known for causing a major social phenomenon. The 2021 film Evangelion: 3.0+1.0 Thrice Upon a Time became a topic of discussion not just in Japan, but globally. The TV anime and the film series have different storylines, allowing fans to enjoy comparing the two. It’s one of the best mecha animes.
The story is set in Tokyo-3, which is under attack by massive creatures known as “Angels.” Military firearms and even powerful N2 mines are useless against them. Amidst the battle, 14-year-old Shinji Ikari is rushed to the NERV headquarters by a woman, Misato Katsuragi. There, he is shown the “Evangelion,” a biomechanical weapon.
While Shinji is still reeling, his estranged father, Gendo Ikari, addresses him. “Pilot the Eva. Or else, leave.” Shinji fiercely resists. When Gendo determines Shinji is useless, he orders a badly injured girl to pilot instead. Seeing the girl cry out in pain, Shinji decides he will pilot the Eva.
The series is still discussed today for its shocking conclusion. Its complex worldview and story, ripe for analysis, have captivated countless fans. Despite its 1995 broadcast, the robot action sequences rival modern productions in their intensity. This is a must-watch for those interested in the pioneer of the Sekai-kei genre.
Gurren Lagann
2007 Broadcast / 27 Episodes
“Believe in the me who believes in you!”
Tengen Toppa Gurren Lagann originally aired in the “Nichi-Asa” (Sunday morning) programming block. Its passionate, classic heroic story can be enjoyed by adults and children alike.
The setting is a world where people live underground, digging tunnels. A young boy named Simon, who has never seen the surface, finds a small drill while expanding his village. His “big bro” figure, Kamina, takes it and declares, “Your drill is the drill that will pierce the heavens,” sharing his dream of reaching the surface.
One day, the village ceiling suddenly collapses. A giant robot known as a “Gunmen” appears and attacks the village. Amid the chaos, Simon boards a small Gunmen he unearthed. Thus begins the long journey of a boy who does not yet know his own destiny.
This work unfolds in four parts, chronicling the protagonist’s growth from childhood to adulthood. While it has comical scenes, it is a masterpiece that is truly heartbreaking when it aims to be. It’s a highly recommended mecha anime filled with quotable, famous lines.
Mobile Suit Gundam: The Witch from Mercury
2022 Broadcast / Season 1: 12 Episodes / Season 2: 12 Episodes
“Mercury’s so uptight, isn’t it?”
Mobile Suit Gundam: The Witch from Mercury is the first TV Gundam series to feature a female protagonist. Its academy setting, perfect hook in the first episode, and a story that pulls you in deeper with every week made it a massive topic on Twitter from its debut to its finale. Season 2 aired in 2023, generating just as much excitement. This is a great robot anime for long-time Gundam fans and newcomers to the franchise.
The Asticassia School of Technology is run by the Benerit Group, an industrial giant. Suletta Mercury, a girl who transfers from Mercury, spots a person drifting in space on her way to the school. Ignoring the operator’s protests, she frantically pilots her mobile suit to rescue them. When she gets the person—who turns out to be Miorine, a beautiful silver-haired girl—into her cockpit, they promptly headbutt her and yell, “Don’t interfere!” Miorine had been trying to escape the school and flee to Earth.
Later, Suletta runs into Miorine while observing a class. As Suletta stammers out an apology, two mobile suits suddenly burst onto the scene. Miorine saves her just as she’s about to be caught in the crossfire. At this academy, conflicts are settled through “Duels” where students bet things of importance, and this battle was an officially sanctioned duel. The pilot was Guel, an heir to one of the “three houses” (Gosanke) corporations. By a strange twist of fate, Suletta finds herself challenged to a duel by him.
Aldnoah.Zero
2014 Broadcast / Season 1: 12 Episodes / Season 2: 12 Episodes
“You are my enemy.”
Aldnoah.Zero is an mecha anime themed around the conflict between humans who once shared a common home. The soundtrack is handled by Hiroyuki Sawano, famous for his work on Attack on Titan and Mobile Suit Gundam UC.
During the Apollo program, an ancient Martian artifact, the “Hypergate,” was discovered on the moon. This unknown technology opened the path for humanity to immigrate to and colonize Mars. However, those who discovered the “Aldnoah” technology on Mars claimed exclusive ownership, founded the Vers Empire, and created a schism between Earth and Mars. After a long war, a ceasefire agreement was eventually signed.
The year is 2014. Princess Asseylum of the Vers Empire, hoping for peace, visits Earth as a goodwill ambassador. Amidst the crowds, the protagonist, Inaho Kaizuka, joins the parade after being dragged along by a friend. Just when it seems the event will proceed in a lively atmosphere, missiles suddenly fly in. The fuse is lit on a spectacular war between Earth and Mars.
The overwhelming military power of the Martian forces versus the desperate counter-attack of the Earth forces. The explosive scenes, which almost feel like a display of power, are breathtakingly intense and impossible to look away from. This is recommended for viewers who want robot action that depicts the horrors of war and powerful human drama.
SSSS.GRIDMAN
2018 Broadcast / 12 Episodes
Flashy action that inherits the spirit of tokusatsu
SSSS.GRIDMAN is an anime based on the 1993 live-action tokusatsu (special effects) program Denkou Choujin Gridman. The story is crafted so that both those who watched the original and those new to the franchise can enjoy it. The designs for both the male and female characters were also highly praised.
One day, the protagonist, Yuta Hibiki, wakes up in a girl’s room. He has amnesia and doesn’t know who the girl is or who he is. As he tries to grasp the situation, a voice suddenly calls “Yuta” inside his head. He follows it and finds an old computer. As if waiting for him, it powers on, and the owner of the voice, “Gridman,” appears. Yuta is confused by Gridman’s words to “remember your mission,” but as he heads to the hospital, he sees a giant kaiju monster outside.
This series is full of expressions that pay respect to tokusatsu, such as the sense of weight in the landing scenes and the writhing movements of the kaiju. The powerful action and superb voice acting are major draws. At only 12 episodes, it’s short and easy to binge-watch. Recommended for anyone looking for an anime with thrilling battles.
DARLING in the FRANXX
2018 / 24 Episodes
“From now on, you are my darling.”
DARLING in the FRANXX is a completely original mecha anime that brought together a dream team of staff who have worked on numerous masterpieces. The opening theme is just as stacked, produced by HYDE of L’Arc~en~Ciel and performed by Mika Nakashima.
In the distant future, the world is desolate. To escape mysterious giant creatures called Klaxosaurs, humanity is governed by the APE organization, which has developed robot weapons known as “Franxx.” The only ones who can pilot these machines are “Parasites”—children. Code:016, “Hiro,” is one such Parasite living in Mistilteinn. Once called a prodigy, he is now seen as a failure and has finally been told he’s washed out.
Dejected, Hiro encounters a girl, Code:002 “Zero Two,” swimming in a lake. He is captivated by the two horns growing from her forehead and by the sight of a girl, naked for the first time. As he laments that he has no place to belong, Zero Two extends a hand and asks, “Won’t you be my darling?”
The robots in this series have feminine bodies, a rare choice for mecha design. But despite their cute appearance, the action is thrilling and satisfying. The swirling emotions and interpersonal relationships among the Parasites are also a major highlight. This is a recommended anime that depicts the growth of these children and the unique bond between Hiro and Zero Two.
