Brain Attack is the tenth Hero Factory television episode.
In a remote location in the galaxy, evil brain parasites are stored in green tubes that are loaded onto small single-use rockets. An unknown villain begins talking to himself about his plan and that with his brain army, he will destroy Hero Factory, and without it, there would be nobody left to stop him. Meanwhile, back in Makuhero City, Bulk, Furno, Stormer, Surge, Breez, Evo and Rocka are spending time with the citizens. Bulk takes pictures with children, Furno makes a brief summary of the recent Catch 'Em and Cuff 'Em operation during an interview right after he begins overusing his flamethrower "Hot stuff, hot stuff!" he explained, only to be stopped by Stormer "Cool it hotshot" Stormer joked, badly. Surge and Breez repair a machine and give autographs and Evo plays a quick game of Roboball. Surge mentions to Breez how he thinks that spending time with the citizens is the most boring part of his job.
The brain rockets then hit various parts of the planet. In a jungle, several Ogrum hear several of the rockets crashing into their jungle, but because they never saw it, they ignore it, just before the brains infect them. In a desert, a Brain sneaks up on a Scarox and infects it. In an icy mountain a Frost Beast notices one of its own species being infected and quickly uncovers the rocket in front of him in order to protect itself, but unfortunately the brain sneaks up behind it and infects it. A Pyrox is seen infected in a volcano, coughing up smoke after the transformation, and it follows several other infected Pyrox. Bruizer is seen searching for diamonds, the apparent diet of its species, and when it uncovers a rock to check for more, a brain attacks it, causing a rock to fall on its head after transformation. Next, an Aquagon is spending a regular day in the water when a brain swims up to it and it transforms. The Aquagon then shakes out a fish that ended up inside its head. Lastly, a single brain arrives and crawls into a cave. Plasma volts are then seen, but the creature, Dragon Bolt, lost against the brain.
Back in Makuhero City, Furno, Rocka, and Evo finish taking a picture with several of the citizens. Furno then receives a code red signal and all of the heroes present go to Hero Factory. As soon as they arrive, Zib explains that the infected creatures are heading toward Makuhero City. Surge is excited that they finally get another mission and immediately heads for the Assembly Tower, followed by the others.
Having received swords, shields, visors, core protectors, and other varying equipment, the heroes leave to get to their mission. Upon getting outside to Makuhero City, Furno uses his visor to map out Makuhero City and any beings there. He then commands the Beta, Gamma and Ceta teams to get to areas 6, 9 and the rear of 12 respectively. Next, he tells Evo to get the creatures in the transportation tunnels, and Surge to guard Hero Factory (to his disappointment, as he had been waiting a long time for the mission).
The five remaining heroes (Furno, Stormer, Breez, Bulk, and Rocka) pass a crowd of fleeing citizens and find the creatures coming all at once in a huge mob. Furno wonders why the peaceful creatures had turned feral, and Rocka uses his visor to detect the alien brains.
Daniella Capricorn also flees but is ambushed by a Pyrox, which Bulk attacks. She continues avoiding the monsters while continuing her news report. Suddenly, a brain jumps up at the lens of the camera, and she angrily strikes it with her microphone, then running again at the sight of six more brains crawling towards her.
Underwater, Evo is chased by five Aquagon while giving a status report, and he quickly avoids a sixth one coming from the other side. He then spins his tornado staff and blows the Aquagon away, temporarily stunning them.
The other heroes continue the fight. Breez is caught by the vine attack from an Ogrum, and is knocked down by a Scarox. She quickly regains ground with the blades on her shield, and successfully uses the Ogrum's vines against it. Rocka then suggests that they attack the brains on the heads instead.
Meanwhile, the infected creatures attempt to attack Hero Factory, but Surge holds them off. A brain crawls up his shoulder, and not knowing what it was, Surge does not attack until the brain tries to get on his Hero Core. Luckily, the core protector protects it from doing that, giving Surge time to reach for his weapon and blast the brain with a shock of lightning, though this backfires as he is also affected, making him dance in an attempt to shake the electricity off. However, the brains surround him, and because he had dropped his weapon and his wings are jammed because of the shock, Surge is unable to do anything about it.
Zib tells Furno that he has lost Surge's connection and requests that someone check for him, but Furno replies that there is nobody to send as they still had to battle. Bulk confuses a Bruizer by mentioning a code that appears to be the upgrade name, "ZX-79". Bulk then searches the weakness of the brain with his visor and finds it- the red spikes on the brain. He then frees the Bruizer by smacking the brain spike, and the Bruizer kicks the brain away. The Bruizer then hugs Bulk hard. After the Bruizer lets him go, Bulk tells the others, including Evo, the weakness and Evo quickly frees the six Aquagon. Stormer frees a Pyrox and Breez goes into a quick run of smacking the brains of the creatures with her weapon. Having defeated all the brains, Breez is contempt until she notices Dragon Bolt coming their way. The heroes avoid a crazy wave of lightning fireballs while Dragon Bolt leaves for Hero Factory. Stormer commands the Alpha Team to follow it, tells Evo to group up and orders the other heroes are to stay and take care of the remaining Brains.
Rocka says he will take on Dragon Bolt himself and asks the others to make sure Surge is safe. As the other five enter the Factory, Stormer decides that someone is using the Assembly Tower. A door suddenly opens containing recently made heroes. Furno notes that the eyes of the heroes have the same glow as the infected creatures, and Bulk mentions that even without a Quaza core they can still fight well. Because of the huge number of heroes, Evo concludes that this was an army and that meant there was a leader, just as they find that a brain-controlled Surge was just that. The heroes are forced to fight the army. Stormer goes up forward as Furno ignites his sword and Bulk throws his shield like a boomerang. Bulk pushes his drill through the body of a hero, and says that without a quaza core, the heroes against them are mindless drones. Evo agrees as he grabs one of the drones and throws it across the area. Stormer jumps up and spins, firing an ice beam that freezes three drones. Breez defeats several drones and says they could fight all day and figures they might REALLY fight all day due to the number.
Rocka walks through a corridor and finds a huge hole. Just as he thinks about the fact that Dragon Bolt might be under there, Dragon Bolt attempts to quietly attack him with its tail, but Rocka notices and immediately avoids it. Rocka shows off about his laser shield and plasma sword, and is barely able to block the lightning fireball with his shield, losing his sword. During the next few shots, he drops his shield as well and immediately gets himself inside the vehicle storage without thinking. Rocka ponders what to do as there is no exit around except the front, which is blocked by Dragon Bolt. He then finds an armed flying machine that he decides might solve his problem.
The heroes continue fighting the drones. Bulk jumps up and causes a shockwave that knocks down a third of them. He then says that at this rate they can win, right before firing a flick missile at a drone. Furno asks where Surge is, and Stormer finds him on the corridor above them. Surge walks over to the Assembly Tower controls and Stormer concludes he is making more drones. Furno orders Breez to stop Surge, and she gets to an elevator shortly after fighting down a few drones.
A siren sounds as Dragon Bolt crushes the Furno Bike. Rocka faces him in the machine and begins firing two Plasma Guns attached to it. Using four flick missiles, Rocka gets Dragon Bolt out of Hero Factory, who leaves making Rocka chase it.
Surge is stopped by Breez who throws her shield at him. Surge attacks her and Breez is forced into a battle between her friend.
Rocka fires more flick missiles and plasma shots but Dragon Bolt keeps dodging. He loses Dragon Bolt, but is ambushed from below. Rocka jumps out of the machine and frees Dragon Bolt, who swallows the brain that had infected it.
Breez frees Surge and scolds him, making him stop the drone army. Zib returns and tells the heroes that the other teams have defeated the brains, which have been stored in the Hero Factory prison and the infected creatures have returned home.
Outside, Dragon Bolt has not left yet and the citizens are repairing the damage. Surge helps a citizen get his car back upright, and finds that doing that felt better than being infected.
Meanwhile, two workers go down the hole that Rocka had found earlier, and finds that the bottom is covered in green goo- and countless, perhaps millions of brains.
