Gurren Lagann Starts With a Robot the Size of a Person. By the Final Episode, the Robot Is Bigger Than a Galaxy.
By Jimigrimm
Simon lives underground. He digs tunnels for a living in a village that has never seen the sky. One day he finds a small robot buried in the rock. It’s shaped like a face. It’s barely big enough for one person to sit inside. That robot is the starting point.
By the end of the series, the mecha Simon pilots is throwing galaxies like weapons.
Gurren Lagann is a show about escalation. Not just in scale, but in belief. Every arc asks the characters to reach further than they thought they could, and every time they do, the show gets bigger. The robot combines with another robot. Then another. Then the combined robot becomes the size of a building. Then a city. Then a planet. Then a solar system. Then a galaxy. The escalation never stops because the show’s entire philosophy is built on the idea that the only limit is how far you’re willing to push.
27 episodes. Produced by Gainax. Directed by Hiroyuki Imaishi. Written by Kazuki Nakashima. Scored by Taku Iwasaki. Aired on TV Tokyo from April to September 2007. Aired on Toonami in the United States.
Where It Came From
Imaishi joined Gainax as an in-between animator on Neon Genesis Evangelion in 1995. He worked on End of Evangelion and His and Her Circumstances. He animated key sequences in FLCL. He directed Dead Leaves, a 50-minute film that was pure visual energy. And the entire time, he wanted to make a giant robot show. He’d been a mecha fan his whole life, and directing his own mecha series was the project he’d been working toward since he started in the industry.
By 2006, Gainax’s most famous creators had moved on. Hideaki Anno left to form Studio Khara. Shinji Higuchi was working in live-action film. The studio handed the next major project to Imaishi and a team that was largely made up of the next generation. Hiroyuki Yamaga, one of Gainax’s co-founders, served as series planner. Kazuya Tsurumaki, who had directed FLCL and Diebuster, contributed storyboards. Masahiko Otsuka served as assistant director. The Gainax DNA was there, but the people driving the project were younger.
The writer Imaishi chose was Kazuki Nakashima, a playwright. Not an anime writer. Nakashima’s background was in theater, and his only prior anime credit was writing a single episode of Re: Cutie Honey for Anno. Imaishi brought him on because they’d worked together on that project and because Nakashima could compress massive amounts of story into a limited number of episodes. Imaishi said he was surprised at how much material Nakashima could fit into 27 episodes.
After Evangelion
Evangelion changed mecha anime in 1995. It took a genre built on heroism and giant robots saving the world and turned it inside out. The pilot didn’t want to be there. The robot was a nightmare. The heroism was a lie covering institutional trauma. After Eva, mecha anime shifted. The genre got darker, more psychological, more willing to question its own foundations.
Imaishi grew up loving the mecha shows that came before Eva. Shows like Getter Robo, where the robots combined and got bigger and the heroes won through willpower. Nakashima was an editor of Getter Robo manga. Both of them came to Gurren Lagann with an affection for classic super robot energy, and the show they made reflects that. The characters face real loss. The grief is real. But the show never stops pushing forward, and it treats the decision to keep fighting as something worth celebrating rather than questioning.
Critics and fans have described Gurren Lagann as a reconstruction of the mecha genre after Eva’s deconstruction. Whether Imaishi intended it that way or simply made the robot show he’d always wanted to make, the result is a series that feels like it’s in direct conversation with what Eva did to the genre twelve years earlier.
The Episode 4 Controversy
Episode 4 of Gurren Lagann aired with noticeably different animation quality from the first three episodes. The style was looser, the character proportions shifted, and fans reacted with enough intensity that it became a public discussion. The production team addressed the backlash. The controversy became a widely discussed production dispute within the anime community, and the episode’s animation director became the center of a debate about artistic interpretation versus quality control.
The rest of the series maintained the production quality that Gainax was known for, and the later episodes, particularly the final arc, are among the most ambitious pieces of animation the studio ever produced.
What Happened After
Gurren Lagann premiered the same year that Anno announced the Rebuild of Evangelion films. Two mecha projects from Gainax alumni, running in parallel: Anno rebuilding the show that defined the studio, and Imaishi building the show that answered it.
After Gurren Lagann, Imaishi and Otsuka left Gainax in 2011 to co-found Studio Trigger. They took the energy, the animation philosophy, and the creative ambition with them. Trigger’s first major original series was Kill la Kill in 2013, which carried the same escalation-as-storytelling approach that Gurren Lagann had established. Trigger later produced Promare, Little Witch Academia, and Cyberpunk: Edgerunners.
Gainax continued without them. The studio that made Evangelion, FLCL, Diebuster, and Gurren Lagann went bankrupt in May 2024. The intellectual properties were transferred to Anno’s Studio Khara. Gurren Lagann’s copyright attribution has since been changed from Gainax to Nakashima, Imaishi, and the Gurren Lagann Project. The full ownership details remain unclear.
The studio that made the show doesn’t exist anymore. The people who made it built a new one.
Did you find Gurren Lagann through Toonami, through Gainax’s name, or through someone who told you it would change how you feel about mecha? Did the escalation hook you from the start, or did it take a few episodes to understand what the show was doing? And the question that always comes up: did the second half hit harder than the first, or does Kamina’s arc carry the whole series? We want to hear.
