Enemy Robots are a staple in the FLCL series and frequently serve as short-term antagonists. They come in all shapes and sizes, are used by Medical Mechanica for a specific purpose, and usually arrive through the N.O. channels created by Haruko Haruhara on an adolescent's head.


In each episode of the original series, a new robot appears and causes trouble for Naota Nandaba and the people of Mabase. Created by Medical Mechanica, they mostly come out through the N.O. channel in Naota's head. These robots come in various shapes and sizes, but they all have the same mission: to capture Atomsk and activate the Medical Mechanica plant residing in Mabase.

Enemy #1Edit

Flcl others0017

The arm's "face."

This robot appears in episode 1. It was actually the left arm of a larger robot. It came through the portal in Naota's head at the same time as Canti did. It tried to pull Canti back through the portal, but Canti was fused with Atomsk at the time and broke the arm from its owner's body. The arm was still functional and acted as if it had a mind of its own. It moved by using its fingers to crawl and jump, and tried to beat Canti by crushing him in its grip. Canti's fusion with Atomsk was powerful, though, and the arm was quickly outmatched. It tried to escape, but Canti caught it by its loose and severed cables and tore it apart.

Enemy #2Edit

Red Canti stops Robot #2's arm.

This robot appears in episode 2. It was the owner of the left arm Canti destroyed in the previous episode. Its missing arm was replaced with a small-but-powerful taser. At the beginning of the fight, Canti did not have Atomsk's power and was not strong enough to defend himself. The enemy robot was a very strong opponent and was able to detach and shoot its remaining arm over long distances. Haruko Haruhara was able to land one good hit on the robot's left shoulder with her guitar, but, for most of the battle, she was busy dodging its projectile arm and was shocked by its taser. While she was down, the robot went after Canti again. Just when all seemed lost, Canti "ate" Naota and regained Atomsk's power, making an impressive comeback. Canti also transformed into his cannon mode for the first time and blasted the enemy robot's single arm. Haruko then delivered the finishing blow and the robot exploded.

Enemy #3Edit

Robot 2

Haruko vs. Robot #3.

This robot appears in episode 3. It is unique in that it came through an N.O. channel in Eri Ninamori's head instead of Naota's. Staying attached to the girl, it took control of her body and used her legs for both attacking and defending. In the novel, Naota compares its appearance to a lemon squeezer. The robot attacked Naota first, but it soon went after Canti instead. After breaking a ukulele against it in a futile attack, Haruko came up with a battle plan. Luring the robot to the roof of the school, Haruko attacked it from above with her guitar while Canti attacked from below. The robot was finally undone when it happened to consume the super spicy curry from Naota's lunch. It dropped Ninamori and fell off the roof, allowing Red Canti to finish it off with a cannon blast.

Enemy #4Edit

The satellite falls to Earth.

This robot appears in episode 4. It was actually a satellite named "Shiosaki" and it contained a very powerful bomb. The satellite was knocked from its orbit by a baseball that Haruko hit into the sky and Naota's head was the beacon that guided it to fall towards Mabase. When it entered the atmosphere, the satellite's main body broke off and kept falling toward Naota's position on top of the Medical Mechanica plant. Naota was able to stop the bomb's fall with his newly acquired guitar and Haruko hit it back into space with hers.

It is unique for being the only robot in this season that was not built by Medical Mechanica or emerging from anyone’s head due to an N.O. channel.

Enemy #5Edit

Flcl others0073

This robot appears in episode 5. It was by far the biggest and most destructive to come out of Naota's head. It wore a long coat-like garment that disguised its hand-shaped body. It was actually intended to activate the Medical Mechanica plant. Upon exiting the N.O. channel, it began walking through the city towards the plant, crushing everything in its path as it did so, towering over all the surrounding buildings. When Haruko attacked it, the robot revealed that it was carrying several gigantic guns under its coat and opened fire on her. Canti came to Haruko's aid, changing into his cannon mode and firing, but the robot knocked the cannon ball, which was really Naota, out of the sky and into a nearby billboard. With no ammunition left, Haruko had only her guitar to fight with, but it wasn't enough and she was shot out of the sky. The robot was finally defeated when Canti used Atomsk's power and struck it down with a guitar belonging to Atomsk himself.

Enemy #6Edit

Flcl others0093

This robot appears in episode 6. It was actually part of the one that was beaten in the previous battle. Called the Terminal Core, the robot was lost in the river until the day Mamimi Samejima found it. Naming it "Ta-kun," Mamimi kept the it as a pet and helped it grow by feeding it, first on cell phones and then on Vespas. Eventually, it grew too big for her to control and went on a hungry rampage throughout the city. Commander Amarao and Kitsurubami attempted to stop it, but their guns were useless. After finding and swallowing a part of Canti, the robot headed for the Medical Mechanica plant and attempted to fuse with the hand, but was still missing Atomsk's power. Haruko solved this problem by feeding it Naota, who is able to channel Atomsk's power through his N.O. channel. The robot then fused with and activated the hand, but it was stopped when Naota broke free, having fused with Atomsk himself. When Atomsk later emerged from Naota's head, he consumed the hand with his own powerful N.O. channel.

FLCL ProgressiveEdit

In season 2 of the series, the robots are no longer arriving in every episode as their plot purpose has changed. Instead of working to activate the Medical Mechanica plant, they seem to target Haruko and her new N.O. channels: Hidomi Hibajiri and Ko Ide.

Enemy #1Edit


This robot first appears in episode 1. It's incredibly large, with a lavender body that is similar in shape to that of a giant clam with three silver crab legs. It has two pink tentacles coming from its maw — one tipped with a three-fingered silver hand, and the other a cylindrical robot eye. It emerges off-screen from Ide's head as a result of Haruko's search for someone with suitable N.O. capabilities and attempts to attack Hidomi. The two students run from it until they are cornered in a junkyard, where Julia Jinyu rescues them with a swift hit from her guitar. It is seen later working small jobs around the town, including as a crossing guard and serving drinks.

Enemy #2Edit


This robot appears in episode 3. It is a gooey looking blob with a radioactive green glow and tentacles. The tentacles on this robot contain four three-fingered hands, an eye, and a dark green tentacle with a projectile weapon. Upon seeing a partially undressed Hidomi being held hostage by Haruko, Ide uses his overflow to his advantage, producing this robot to follow his commands. He has it fight Haruko for him while he attempts to free Hidomi, only for Haruko to get her. The battle blows up the factory they are in and he uses the robot to chase Haruko through the skies. It is eventually commandeered by Haruko after she knocks him off of it, where she uses it to shoot green fireballs at him and Jinyu. It is defeated by a crash-landing from Haruko once it outlives its usefulness.

Enemy #3Edit


This robot appears in episode 4. It somewhat resembles a head with oval feet, purple arms with three-fingered green hands, movable mouth and eye parts to display shock, and many other unique details. It emerges from a portal in Marco Nogata's head, which he got from bumping heads with Hidomi, after being flung from an experimental, N.O.-inducing amusement park ride. It is unique in that it clings to a bamboo pole also coming from Marco's head. It also specifically targets Haruko with its missiles, angering her by intervening in her fight with Jinyu. She seemingly destroys it by throwing Jinyu's car at it, though Jinyu rescues the vehicle to save Ide and Hidomi so it is unknown what caused the explosion. It is possible it hurt itself attempting to defend with missiles.

FLCL AlternativeEdit

N.O. has a less direct effect on the spawning of robots in FLCL Alternative. N.O. channels instead draw robots to the vicinity through intense internal N.O. activity in a user. Medical Mechanica's global presence allows for robots to appear from seemingly nowhere in many cases. The only robot directly spawned from an N.O. channel similar to previous seasons is Enemy #3, a harmless screen that only serves to reinforce Kana's moral lesson.

Enemy #1Edit


This robot debuts in episode 1. It is an amalgamation of metal brought together by a large transmitter, resembling a red pin used on maps, that fell from space. It has a toy soldier's head on top of a round, lavender body with a big mouth. The lips are purple with two large yellow M's on the center of each, as well as yellow and white "teeth" housed inside that it uses to attack. It has a small black circle supporting it underneath with metal legs, wires and other tentacle-like appendages attached. When attacked by Haruko, the toy soldier head loses its human qualities, leaving only its white core and glowing red eye on a wire. Its limited movement made for an easy take-down from Haruko at first, but it gathered more metal to grow in size until it resembled a dragon head with two large supports. This form had many more tentacles that required fast movement, and a hard hit from a guitar caused it to explode.

Enemy #2Edit


This robot appears in episode 2 as a result of N.O. activity triggered by Kana's investment in Hijiri's turbulent relationship. It takes inspiration from Autobot Bumblebee from the live-action version of the Transformers franchise, being made up of Toshio's yellow car with the ability to transform from mech to car and back again. It can fire lasers, travel at incredibly fast speeds, and handles cannon shots from Haruko's guitar with ease. Haruko defeats it by pile-driving a giant rotisserie meat pole into its head, creating a giant explosion.

Enemy #3Edit


This robot grows out of Kana's head in episode 3 after kicking a Medical Mechanica pin causes her N.O. to act up. Its lower half is a purple tentacle that it bounces around with by curling it tight and releasing the tension, and its upper half is a screen with an antenna coming out of the back. Medical Mechanica's yellow logo resides on the right side of its screen and it wears headphones constantly held in place by a red hand on its head. Its screen displays the cryptic message, "Leave her alone..." to Kana, possibly hinting at her intervening in Mossan's life, but it does not seem to pose any threat. Immediately after, Haruko drops from the sky and defeats it with an x-slice to its screen using two signal batons meant for conducting traffic. After being defeated, the robot begins ringing like a phone, exciting Haruko with the possibility of finally contacting her superiors, but it is followed by dial-up noises that infuriates her. She stomps on the robot until the ear-splitting sounds cease.

Enemy #4Edit


This robot randomly appears in episode 4 behind Haruko and Kana's friends, likely drawn out by Kana's N.O. acting up. Its first form resembles a tall person with a giant nose for a head and a pig-like fat distribution and nose, as well as wearing ski goggles where its eyes would be and a light blue basketball uniform. The fleshy nose eats Sasaki, merging their consciousness and causing it to transform into a giant, long-limbed creature with a Minotaur head. After briefly entertaining the basketball loving-robot with some keep-away, Haruko defeats it by hitting its head with a dunk from the three-point line for style.

Enemy #5Edit


Episode 5 sees the return of Enemy #1 in Terminal Core form. This form is largely composed of the proportionally large lips of the original robot, connected to a pink orb for a body, and it scuttles around via small wires connected to its base. It crawls out of the rubble of the hangout it destroyed in episode 1 and scurries around Pets' legs before swallowing enough wires to become a giant, hand-shaped robot that traps Pets in its wire-filled body. This new form is a dark purple hand sitting atop the support foundation from its first appearance, with new legs to match. The foundation is white with yellow circles on the bottom and purple stripes, as well as wires dangling from various holes beneath. The hand portion has a mouth in its palm left over from the Terminal Core's form and a dragon-like head stitched onto the index finger. Laser openings are on the thumb, middle, and pinkie fingers, and a claw covers the top of the ring finger. There is a crack in its body showing the wires where pets is trapped. This robot is attacked by Haruko, but ultimately gets teleported elsewhere or destroyed by Kana's N.O. channel in an act of desperation to save herself and Pets.

Enemy #6Edit


Throughout episode 6, Haruko and Kana are harassed by several robots resembling Canti that protect Medical Mechanica's irons from destruction. During her first attempt, wherein Haruko tried drilling into one iron from above, she fights one of these models in a one-versus-one battle that almost ends in a fatal draw. Later in the episode, the models attack in droves as Haruko and Kana's friends attempt to help her tap into her full N.O. power. Many of the robots are defeated by Haruko's guitar and Vespa, as well as her natural superhuman fighting abilities and Kanda's gun. The remainder all get pushed by the explosion caused by Kana's N.O. into the Naked Focal Point her N.O. channel creates. These robots differ from Canti in color, fight with melee weapons such as pipes, swords, knives or spiked bats, and lack the ability to turn on their screens in the way that Canti could to function similarly to an N.O. channel. The latter also means that a hit from a guitar does not knock the evil out of them like with Canti.
