This is Keroro Gunsou movie 3 subbed by Keroro-Fansubs. It's a better version than HKver.
The movie begins with Fuyuki Hinata and the Keroro Platoon exploring an abandoned temple in the mountaintop city of Machu Picchu in Peru. While on the exploration, Keroro accidentally sets off a trap, and by chance they find a hidden chamber with a large blue crystal in the center, on a stand that has a key in it. Keroro leans on the key, causing the room to activate a mysterious machine, this caused the entire temple to shake. As soon as the group realized what was happening, they run out of the room. While running, Keroro accidentally loses his Kero Ball while Fuyuki catches a fleeting glimpse of a glowing young woman as he is running out, and tells Keroro that there was a girl in the room, but he is forced to leave the room before he can say anything else. The group successfully escapes, while the girl (now sprouting a pair of glowing wings) watches them leave - while back in the chamber, something is growing within the crystal...
Our story continues back in the Hinata household, where Natsumi and Koyuki exchange conversations with Fuyuki about Machu Pichu. Natsumi was about to drink a mysterious bottle of fluid, when Keroro saves her at the last minute, telling her that the bottled drink was actually a type of weapon drink called "Nanora", whatever the liquid touches turns into a terrifying weapon of destruction. Fuyuki then reminds Keroro that a new Gunpla has arrived at the toy store, however, Natsumi told him that he still had chores to do. To cheer his friend up, Fuyuki said that he would buy the new Gunpla for Keroro, overjoyed from Fuyuki's kindness, Keroro gives him his wallet to use for Gunpla.
Meanwhile, an unknown group was watching them. The leader was quite disturbed by Keroro's lack of leadership, and decided to relieve him of his duty of invading the planet. At the same time, Momoka called the Keroro Platoon over to have them answer for an unknown installation on her family's super computer. They stated that they weren't responsible, but then, a soldier reported an unknown object coming rapidly towards them.
After Fuyuki was finished buying Keroro's Gunpla, he, as well as everyone living in Tokyo, witnessed an enormous ship appearing out of the sky. The Platoon runs outside the Momoka mansion to meet the invaders. The first was Shivava (Cibaba), a Keronian with a distinctly cocky attitude (as indicated by his self-declared title of Great Sage Surpassing Heaven) that makes Tamama envious. The second to appear was Doruru, the trainer of the first Keron Army that Giroro served with. The two invaders revealed that they weren't working for the Keron Army, but instead were working for another Keroro, this one looked even darker than the original, Dark Keroro. He arrived in a darker and more sinister version of the Keroro Movie Mecha to declare himself the new king of the world. He proceeds in telling the platoon of the current situation, his domination of the world in 2 minutes. During the first minute, he took control of all the economy and super computers on earth, he then proceeds to the market, the military, and so on, that made one minute complete. In the second minute, he sends greeting cards to all the world leaders, and immediately sends his Mini-Keroro robots across the globe, to land and send out hypnotic waves to brainwash all who reside in the area, including Natsumi and Koyuki.
Suddenly, Fuyuki arrived, shocked after seeing everyone in town acting strangely. This was something Dark Keroro didn't think would happen, a regular human, immune to the hypnotic signal? Dark Keroro was surprised, but it wasn't anything to worry about, since he is planning on the Giant Keroro Statue, a weapon said to be the ultimate destroyer. Dark Keroro then jumps into his Dark Keroro Mech, then proceeds into attacking the group, as well as Fuyuki. After the onslaught, Dark Keroro and his followers leave for their ship, without knowing that Keroro is following them by hovership. Meanwhile, Mois, unaffected by the waves, arrives to help Fuyuki take care of the other platoon members, while those who ARE under the waves control are working on parts of the Giant Keroro Statue. Fuyuki then leaves to help Keroro by using another hovership while Mois helps the battle-damaged platoon members, Giroro wakes up in time to hear from Mois what has currently happened, then Dororo arrives to tell them what happened to their friends.
Fuyuki arrives atop of the ship to see a wondrous view of the cities that lie on top, the hovership he was on broke down and was plummeting down, then he was saved from falling by an angel-like woman named Nazca (Masuka), the same woman he saw in Machu Pichu. After Fuyuki and Nasca parted, Fuyuki found a passage inside the ship. Giroro and Dororo were trying to get through to Koyuki and Natsume, who were already under the control of the Mini Keroro's hypnotic waves, but nothing happened, Tamama wondered why they weren't under the wave's control, and Dororo said that it was because they were Keronian, and a Keronian weapon can't effect other Keronians. Mois said that neither her or Fuyuki were under the Mini Keroro's control, thus raising the question as to how that's possible.
Somewhere in Dark Keroro's ship, Keroro and Fuyuki reunited, only to be washed away by the tide of water that goes through the underground hall, Fuyuki and Keroro were then saved by Keroro's hovership, just in time for they're friends to arrive and help. They were then ambushed by Shivava, and then afterwords, imprisoned in the ship's barrier by Miruru, the ship's system operator. Doruru arrives to blow the group out of the sky while Kururu is forced to deal with Miruru. Doruru succeeds in shooting them down, forcing Dororo to catch them all on his shuriken hoverboard - the resulting overload causes him to crash-land in what appears to be a colosseum.
When Fuyuki, Mois, and the Keroro Platoon regain consciousness, they find Koyuki and Natsumi preparing to fight each other, due to being under Dark Keroro's hypnotic weapon's control. Kururu then reports to the platoon that Dark Keroro is a clone of Keroro, grown from a sample of Keroro's DNA off the Kero Ball, enhanced by super carbon and educated in a different way then Keroro was. After the discovery, they witness Koyuki and Natsumi's mindless battle with each other, this forces Giroro and Dororo to fight their friends and try to save them. While the friends were fighting each other, the answer to why Fuyuki and Mois were immune to the hypnotic rays was revealed, Mois's wrist protector which keroro gave her and the wallet that Keroro gave Fuyuki to buy the newest Gunpla, are Keronian items, thus giving the one in possession of the item complete immunity of the hypnosis weapon. Keroro and Fuyuki told Giroro and Dororo about the Keronian items, and told them to place one of their things on Natsumi and Koyuki. Giroro throws his trusty bandolier on Natsumi, while Dororo throws his ninja knife on Koyuki's shoulder pad: these items freed the two girls from the mind control.
The entire group makes a run for it (though Giroro has to be carried away as he is rendered helpless without his bandolier), but were cornered by Dark Keroro and his subordinates. Fuyuki takes a gamble on Dark Keroro's similarity to Keroro, and tries to distract him by throwing Keroro's new Gunpla into the air: the plan falls flat as Keroro himself runs after it. Shivava unwittingly blasts a hole in the ground of the colosseum; Keroro and the others made their escape through the hole, then evade the pursuing Shivava when Fuyuki triggers a convenient trapdoor beneath them.
The kids (Fuyuki, Natsumi, Koyuki and Mois) and the Keroro Platoon rest for the coming battle. Tamama and Giroro in the meantime were wondering if they could defeat Shivava and Doruru, then Mois and Natsumi gave them words of encouragement that gave them hope for their rematches with the two soldiers. At the same time, the everpresent mind-control problem is rectified when Giroro hands Natsumi his bowie knife and takes back his bandolier (and returns to full form as a result), while Dororo simply exchanges knives with Koyuki.
A few hours later, Kururu made an astonishing discovery, apparently, the Keronian weapon Kiruru, the same weapon that threatened the planet twice (it used people's negative emotions against them in Keroro Gunsou the Super Movie, and then possessed Meru in Keroro Gunsou the Super Movie 2) was threatening the planet once again. As it turns out, Dark Keroro is actually the 3rd generation of Kiruru. The first Kiruru was created for enemy alienation, whereas the second was made for destruction, the third and final one was made for one thing, and one thing only, absolute rule.
While the team was planning on how to defeat the third Kiruru (Keroro actually resurrects his rather harebrained scheme from the 2nd movie, involving everyone dressing up as princesses), an army of bracelets attached themselves to each one of them, and with a bright light, they disappeared from each other's sight. The bracelets were revealed to be Dark Keroro's newest weapon, the "Super Anti-Barrier", the wearer can neither hear or see other persons wearing the bracelets. Dark Keroro then separates them, planning on them to lose hope and become lost and alone forever, however, Kuyuki and Dororo don't need to see each other, they have been through events like this before and could easily sense each other's presence. While separated from the others, Fuyuki met with Nazca once again, only to be brought to Dark Keroro's throne room.
In the meantime, the rest of the group were still trying to look for each other, when Giroro wished for a weapon, Natsumi thought of the same thing, as did the rest of them. Nasca was revealed to be Miruru all along in disguise. As Miruru left, Dark Keroro proceeded in inviting Fuyuki to join him as his soldier, but Fuyuki declined. Confused, Dark Keroro threatened Fuyuki to join because he demanded it, causing Fuyuki to state "If that's the only way you can get others to submit to you, then you are not a king!" This angers Dark Keroro even more, so he gives a direct order to Shivava and Doruru to find and kill Fuyuki's friends, but Shivava and Doruru declined the order as well, they even told him to shut up.
Meanwhile, still concentrating on the group's thought of a weapon, Keroro ran straight to his Gundam model in the colosseum, where everyone else came, they all still couldn't see each other, but it didn't matter to them, they knew that they were together, and in celebration of finding each other, they built the Gundam together, forming a complete Mobile Suit action figure. Keroro then proceeded in pouring some of the Nanola on the Gundam, changing it into a giant robot, just like the giant mechs in the Gundam franchise. At the same time, Kururu and Saburo finished work on an entirely new weapon, the Maker Kururus, thousands built with the technology to negate the Mini Keroro's brainwashing waves, and restore the people of earth back to normal, and freeing Momoka and her military squad as well. Keroro pilots his new Gundam robot straight at where Dark Keroro is, at the same time, Miruru uses the ship's defenses to attack the Gundam, blasting whole pieces off of it, until Koyuki and Doruru destroyed the combat system within the ship, causing everything to break and go haywire.
With the Gundam reduced to a mere Core Fighter (the Gundam's cockpit fitted with its own propulsion system, like a minijet), Keroro finally made it into the enemy's throne room. As Fuyuki was trying to get Keroro out of what was left of the Gundam, Dark Keroro tried to convince him that it was pointless to try and save him, however, their bond was too strong for Dark Keroro to understand, and Fuyuki pulled Keroro out of the ship. Just when they started to rejoice, Dark Keroro screamed and summoned his Dark Keroro Mech to destroy both Fuyuki and Keroro. Dark Keroro is now determined to kill Fuyuki, seeing this coming, Keroro places Fuyuki inside the Gundam cockpit, knowing that he should be safe. Dark Keroro then focuses on killing Keroro, but before he could land a punch, something came out of nowhere and punched HIM. It was Keroro's own mech, the original Keroro Mech, remote controlled by Saburo to come straight to Keroro's aid. The two mechs fight each other, leaving Fuyuki concerned about Keroro and what would become of him, as the battle progressed further, Keroro seemed to have the upper hand, until Dark Keroro shot one of his mech's arms off, giving Dark Keroro the perfect opportunity to attack, when suddenly, Fuyuki came in the way of Dark Keroro's deadly attack by ramming the Dark Mech with the Core Fighter.
The Dark Mech crashed and Keroro claimed victory. Dark Keroro called Shivava and Doruru for back-up, but he was rejected again. Dark Keroro then fell into despair, he had no one to help him, and no weapon to use, Keroro wanted to negotiate a cease-fire, but Dark Keroro refused, knowing that no one would obey him, he then set off a switch that made the Super Anti-Barrier glow even brighter, when Fuyuki opened his eyes the first thing that he saw was gunfire, gunfire that came from Keroro's mech and destroyed the Dark Mech completely, he even blew Dark Keroro into pieces. Keroro was speaking like a deranged villain, he even said that he would kill Fuyuki, his friends, and destroy the entire planet; terrifying as it is, Fuyuki wasn't buying it, he knew Keroro wouldn't crave for blood, so Fuyuki uncovered the truth, that wasn't Keroro at all, it was an illusion. The fake Keroro dissolved into nothing as the real Keroro emerged, free of the illusion; the successful resistance to the Super Anti-barrier destroyed the bracelets that were attached to the others.
Dark Keroro couldn't believe that they overcame his Super Anti-barrier's illusion, Keroro and Fuyuki were convinced that Dark Keroro was as rotten as they come, and could never be forgiven. However, Dark Keroro had one more trick behind his sleeve, The Giant Keroro Statue. The Statue parts have gathered together and the group could only watch as it is pieced together piece by enormous piece. However, the ship itself is a piece to, the tipping causes everyone to fall off, including Keroro, Fuyuki tried to save him but it was too late. The others are rescued by Momoka, Kululu and Mutsumi, and they witness the completion and raw power of the Keroro Statue. The kids and the platoon prepare for the final battle, as Giroro and Tamama are confronted by Shivava and Doruru, Koyuki and Dororo deal with the Statue's defences. Dark Keroro and Fuyuki view from the top of the Statue to witness the strength of Fuyuki's friends, Dark Keroro started losing it, he questions Keroro about the bond that he and Fuyuki have, and Keroro told him that there was nothing special, and then Fuyuki said "Caring for friends is something that's shared by all, including humans and invaders." Dark Keroro still couldn't understand, and then, an explosion from one of Momoka's military ships blew off a piece big enough to crush Dark Keroro, but before he could meet his end, Fuyuki and Keroro protected him by shielding him from certain death.
Back in the aerial battle above, Tamama is unable to gain any edge over Shivava, until he snaps into full psycho form and lets loose with all his dirtiest tricks - from farting into Shivava's face to ganging up with Momoka and clobbering him into submission; Giroro defends a battleworn Natsumi by charging at Doruru and risking a barrage from Doruru's own Dendrobium mecha, until Natsumi returns Giroro's bowie knife and he shoves it into Doruru's weapons, allowing Giroro to defeat him.
Dark Keroro finally started to understand Fuyuki and Keroro, and blamed himself for everything that happened, they told him that Kiruru is to blame, not him, so Dark Keroro decided to go alone and stop Kiruru, and then Miruru appeared, it turns out, Miruru is the key to seal away Kiruru, just like Mirara from the First Movie. Miruru warns Dark Keroro that if he does succeed in sealing Kiruru, then Dark Keroro himself will disappear, he didn't care, but Fuyuki did, before Dark Keroro continued, Fuyuki told him that they could be friends, hearing that made him happy enough to save Fuyuki's planet. Dark Keroro seals away Kiruru, and disappears, along with the Keroro Statue, everything fell apart, Fuyuki could only watch as a good friend lost his life for a small planet. The sun rises, and Fuyuki and Keroro stand in the rubble where the Giant Statue used to be, but to their amazement, Dark Keroro was alive and well (his normally red eyes now black, and with an afro to match), it seems that he didn't disappear because the part of him that was a king died, while the other, lived as a friend.
More episodes is coming soon. How's that? Ke-Kero!
