Some initial notes:
This first chapter is basically a prologue to my Keroro Fanfiction. I was just testing grounds, trying to write Keroro's characters mostly in character before going to the main premise, which only really starts in the second chapter.
Aside from the main story itself, there are pictures, usually showing the new designs from each chapter, which can be checked out in my profile. I don't draw very well, but it'll help visualizing the new designs. New pictures are usually uploaded there alongside new chapters.
I welcome any criticism, as well as help if anyone wants to help me checking grammar and oddly worded sentences.
The basic idea for this fanfic came when I saw a pretty good Japanese fanart featuring a girl loosely based on Keroro. I looked at the artist's page and found some comics based on that idea, although they seemed to be AU, changing everything since the beginning. Anyway, for this fic, I decided to expand that basic idea, turning the entire platoon into girls, rather than just Keroro and deviating from a specific point of the anime, rather than just changing everything from the beginning.
Why turn the Keronians into human girls rather than writing some alternate universe fic where they always were girls? Changing Keroro and the four other main Keronians into human girls is already a big enough change from the standard series, if I also eliminated the backstory, it'd be even more distant from it. I'll try to give relevance to the events that happened in the series before this story starts (up to the end of the 5th season, including the 4th movie) and keep everyone in character (well, as in character as possible under these circumstances), not just ignore what is already there.
If this were an AU that changed things since the start, either I'd have to repeat several of the series events, or everything would play out in a really different way. It'd have its appeal, but that's not what I want to do here. The one alteration to the actual setting that I'll use here is that it has been 2 years since Keroro arrived, with everyone 2 years older than in the 1st season, rather than keeping the ages inconsistent like in the tv show, which sometimes hints at time passing and other times completely ignores the idea. Anyway, I hope this will be an enjoyable story.
PROLOGUE
Years ago, invaders from space had appeared. With their superior technology, humanity should have no chance against them. However, more than 2 years had passed… life went on as normal, nothing had changed.
The headquarters of the aliens was located under a seemingly normal house in a seemingly normal city. The Hinata's residence, located in Oku-Tokyo's residential area, was big for a Japanese house owned by a middle class family, including a small yard surrounding the building itself. Besides the size, apparently the only odd sight there was a tent always kept open in the house's back yard.
A young teenager sighed. He sit on a sofa in the living room, his head leaning on the couch as he looked upwards. "The sergeant's plan failed again… but this was tiring." Fuyuki Hinata always dreamed about aliens, ghost and other paranormal creatures, and he ended up finding those in his very home. However, sometimes things got just too dangerous and hard, especially to someone who wasn't good at all at sports and physical activities like him. A wild strand of hair stood like an antenna above his head while his tired eyes looked at the TV. He wore a white shirt and blue pants, a bit drenched in sweat, but nothing out of the ordinary for someone who had ran for a few minutes… although one could say that running around was extraordinary for that boy. In any case, he picked up a remote control and turned on the TV, just passing through various channels without focusing on anything. However the sound of a loud explosion stopped him immediately.
"What is it this time, sergeant…?" Fuyuki slowly went into the old basement, the place that had been used as the little alien's bedroom since they had found him. He opened the door with the star insignia, expecting to see the green alien frog with a giant afro; however he couldn't see the alien sergeant anywhere in the room. Even stranger, there were several girls there. Four of them were just lying on the ground, while one was closer to the door, with green hair, was seemingly sitting still, with her head lowered and her legs bending in uncomfortable way. What had the sergeant done this time?
Fuyuki approached the green haired girl and held her shoulders, shaking her a bit. "Hey! Are you okay?" She was young, around Fuyuki's own age and her face was pretty, with soft features and a smooth, although oily, skin. Although he had never seen her before, there was something strangely familiar about her. Her bright green hair tied in a ponytail and a yellow star shaped ribbon keept it in place. She was wearing a small and short sleeved green jacket over a white t-shirt, a yellow star drawn over the left side of the jacket.
The young Hinata was mesmerized by her looks for a moment, there was just something really exotic about her… like someone from another world, but he quickly shrugged it off. "Is she an alien?" Almost as if answering Fuyuki's question, she opened her large dark eyes.
"Huh…?" She moved her arms forward, holding onto Fuyuki to get up.
"Is that the Keron star?" Fuyuki asked himself while looking at the emblem on the girl's chest, while she slowly stood up, her legs still trembling, barely supporting her own body. Even though she looked frail, she wore green combat boots and knee pads, giving her a vaguely militaristic look, in spite of her small khaki shorts.
"Hi-hi, lord Fuyuki…" The girl said as soon as she opened her eyes while a weak smile was drawn by her lips.
"Lord Fuyuki…? Are you friends of the Sergeant?"
"Gero? What are you talking about, lord Fuyuki?!" The girl raised her hand in a salute, "Don't you recognize me?! I'm …!" She suddenly stopped, her pupils shrinking as she looked at her own nimble hand in disbelief.
"Is there any problem?" Fuyuki asked, slowly stepping away from her.
She quickly ran to a nearby mirror, staring at her own image incredulously. "I'm a Pekoponian?! GEROOO! "
How did everything end up like this? Well, everything started a few hours before those events…
/KeroGirls - Zero: Samama, aim for the top frog! Yes, sir!/
Everything started during another meeting of our aliens, the five members of the Keroro Platoon. In some ways, they fit perfectly the traditional image of the stereotypical alien from humanity's imagination: Small bodies, large heads and eyes, advanced technology that could seem like magic even to modern men, existing beyond a veil of obscurity thanks to a technology called "Anti-Barrier".
However, those were the same creatures completely unable to advance their invasion one bit after spending years on Earth. Even their looks, though, in a way, resembling generic aliens, actually resembled more plush frogs. Their heads and eyes were almost perfectly circular when open, the skin of each one having a unique vivid color. Even though they were all supposed to be soldiers, their only vaguely militaristic detail was their colored hats, with large ear covers covering the sides of their heads.
They were all in the sergeant's room, a small underground bedroom that looked absolutely… normal, if a bit nerdy. A widescreen TV surrounded by complex sound equipment, a metallic stand with some robot and racing car models next to a wall, a small white fridge with a yellow star on the door, a blue sofa and some brown boxes next to the stand. In the center of the room, there was a rectangular purple table, four aliens were sitting in small white chairs there, discussing new strategies to conquer Earth, or, as they called it, Pekopon.
"So, Keroro, what's this new plan of yours?" Corporal Giroro asked impatiently, slamming his red arms against the table in Keroro's room. Just how many times would Keroro play around before doing something to conquer Pekopon? Giroro was the mobile infantry of the platoon, someone always ready for combat. The most serious and experienced member of the platoon, as a scar across his left eye showed… Keroro's lax attitude utterly annoyed him.
"It seems everyone is here already, of course, so let's begin the operation meeting. Understood?" Sergeant Keroro was firmly grinning, crossing his green arms in front of the yellow star on his white belly. Keroro was the leader of the platoon, of course, but often was more interested in plastic models and other human hobbies rather than actually invading anything. However, he had promised to himself that everything would be different that time. Pekopon would be his, and he'd hardly have to do any work.
"Thanks to Kururu's new invention, our victory this time is assured!" Keroro raised his arm excitedly, but the other Keronians didn't show any of his enthusiasm.
"So, it's just another one of Kururu's toys…?" Giroro sighed.
"The corporal is right, sergeant." Tamama agreed, moving his black arms to his back while looking disappointedly at his leader. He was the youngest Keronian in the platoon, the only one who hadn't fully matured physically, still showing a tadpole's tail and a large white area on his face. "It just won't be enough."
"What exactly is this weapon, commander?" Dororo, the blue keronian, showed interest in the subject, unlike the other frogs. He leaned forward in Keroro's direction, somehow speaking clearly through the light blue cloth that covered his mouth. He held onto a small sheathed sword, pulling it the sheath to reveal a small part of its blade "You know I shall absolutely not tolerate any dangerous weapons used against the Pekoponians! Our invasion has to be a peaceful one."
"Heh. This won't hurt anyone." A yellow Keronian wearing huge glasses and headphones interrupted him. That was Sergeant Major Kururu, the platoon's highest ranking member and also a mechanical, biological and digital genius. He was holding his newest creation, a small green gun, patterned with yellow stars and blue circles that looked more like a plastic toy than an actual weapon. "You still remember the "We all live together" gun that we used to try to create an army…?"
"Yes, and it failed completely. Attempting to turn animals into Pekoponians and use them as soldiers was a stupid idea from the beginning. If it were that easy, we could just have used regular Pekoponians! None of the animals we turned into Pekoponians did anything for us. So, what's with this stupid idea again?" Giroro inquired, tapping the table impatiently with his fingers.
"It's a stronger version of that weapon. With this, even one's nature is heavily changed, fitting completely into his new form. Due to its more specific design, the effects are permanent too! Ku! Ku! Ku!" Kururu laughed, characteristically covering his mouth with his hand.
"Humph. I don't see how that'd help the plan. If the animals feel like real Pekoponians, they won't help us!" The Corporal opposed yet again.
"Who said anything about animals, Corporal Giroro? Gero, Gero!" Keroro took the weapon from Kururu's hands. "This is a "You're one of us!" gun, with this, we'll be able to turn humans into Keronians! Understood?"
Silence followed Keroro's announcement, although soon Tamama cheerily leaned forward on the table.
"I know! I know! You'll turn everyone in the planet into keronians, then it'll be ours! The Sergeant is great!" Tamama jumped forward enthusiastically, but Keroro just stepped aside.
"Actually, private second class Tamama, that's wrong too! It'd be impossible anyway… it'd take far too long… and I'm sure the army wouldn't be happy about the result. I have other plans… I'll just use this on a single Pekoponian and recruit that person to our platoon!" Keroro grinned.
"Now, you four wait here, I'll bring the new member of our platoon, got it?" Keroro continued, quickly leaving the room.
"Hm… I don't know if I approve this plan yet. Changing the nature of a living being… warping their mind and will… that's dangerous and vile." Dororo objected.
"Only one person?" Giroro looked at Keroro curiously. "Who could be this Pekoponian?"
"I'm saying it could be dangerous, leader!" Dororo repeated, speaking in an even lower tone. Just to be ignored again.
"I think the answer is easy, Corporal Giroro." Tamama added.
"Huh?" Giroro looked puzzled at Tamama's observation.
"You're all so cruel…" Meanwhile, Dororo had already retreated into his own world, sitting on the wooden floor and falling into a pit of depression after being ignored several times.
"Ku! Ku! Ku! Are you that dense, Giroro?" Kururu grinned. "Think about it. Who's the one who always bests us? Isn't it obvious?"
"Wait… you don't mean…" Various thoughts flew through Giroro's head in an instant. Keroro wouldn't do that right? Not to her?! "I have to stop him!"
"Oh, no, you won't. I press!" Kururu pressed a red button on the middle of a small remote control. Several hidden steel cables broke through the floor, flying and wrapping themselves around the red keronian.
"NATSUMI!" Giroro yelled and contorted his body, trying uselessly to escape from the metallic cables.
Immediately afterwards, the cables grabbed Dororo too. "Eehh!? I hadn't done anything yet!"
"Preventive action." The Sergeant Major turned to Tamama. "So, are you going to do anything too?"
"O-of course not!"
/-
Keroro sneaked around the living room, trying to find the perfect spot to prepare an ambush to Natsumi. He hid behind a sofa and slowly walked backwards. However, he ended up stumbling on something. The green frog turned around, just to see the long legs of a human girl. "Lady Natsumi!?" Although she was only slightly taller than an average 15 years old Japanese girl, that still was enough to tower over the surprised alien, who, for a moment, looked in horror at the girl wearing a reddish vest over a long sleeved white shirt and blue jean shorts.
"What do you think you're doing, eh, stupid frog?" The redhead wondered, grabbing the alien sergeant by his large head, her short but thick twin tails shaking as she shouted at the unlucky frog. However, he just grinned, infuriating her even more. "What is it?! Are you preparing another useless plan to conquer Earth?"
"Actually, Lady Natsumi, this time I thought about asking for your help." The small alien wore an obviously fake smile, with his black pupil contorting into a horizontal line across his large white eyes.
"Eh?" Natsumi took a step back, after noticing Keroro's attitude. She really didn't like when he actually attempted to do something serious and that face seemed to suggest just that. The silence was broken when a small noise came from the lower floor. The girl briefly looked below her, as the noise returned constantly, getting louder and louder.
"NATSUMI!" A wall exploded, and Giroro jumped through the resulting smoke, still attached to the large steel cables.
"Giroro?!" Natsumi released the green frog and jumped backwards, dodging Giroro's rush.
"Chance!" Keroro fired the gun just as he fell on the floor, "Turn into a Keronian, Lady Natsumi!" A ray of light crossed the room, hitting Natsumi's body.
"Wha-what!?" The redhead looked at her own body when it started shinning. "You'll pay for this, stupid frog!" The light engulfed her, quickly stabilizing in the shape of a luminous egg. Afterwards, it started to shrink, although the glow continued.
"Gero, gero! So, new member of the Keroro platoon, come forth to your leader!" Keroro grinned.
"Who's anyone's leader?!" A small figure jumped from the fading light, punching Keroro into the nearby wall.
"Huh?" Giroro stared wide eyed at Natsumi's new, keronian, form. She had light red skin, a pink helmet which resembled vaguely her own hair style, and a keronian "n" on her chest and head. Like most female Keronians, her face was mostly white, with the light red tone only above her eyes, and she had a tadpole's tail. "She's… she's still lovely…"
"What are you looking at?!" The new keronian glared at Giroro. "But… this isn't so bad, I guess…" Natsumi raised her arms, moving them back and forth. She then punched and kicked the air several times.
"So, you're already getting used to your new body, new recruit Natsumi! Now, then, let's start our operation!" Keroro proudly proclaimed, crossing his arms.
"Shut up, stupid frog!" The new red frog punched Keroro's head, sending him straight into the wall again. "Huh… I'm a frog now too… So…that's kind of weird, right?"
"Then, you'll call me Sergeant Keroro!" The green Keronian stood up again, battered, but smilling.
Natsumi just grinned, "Stupid green seems good enough for you, stupid sergeant."
"Gero? That doesn't sound any better."
"By the way", Natsumi continued, smiling to Giroro, who was even redder than usual. "You want to conquer Earth, right? But you always waste time with useless things, that's why you never do it."
"Natsumi? Are you… Are you really Natsumi?" Giroro asked weakly, pushing his body against the wall to stand up.
"Natsumi…? It doesn't sound right for a keronian, does it?" The female keronian smiled to Giroro, pointing confidently at herself. "Anyway, I've decided… Somehow, feel like going along with your stupid plans to conquer Earth this time. And, with my help, we'll win in no time!"
/
"So… this is the plan. We'll sell the Sergeant Keroro CDs and conquer the hearts of the Pekoponians! After we're famous throughout the world, conquering it will be easy!" Keroro loudly announced his plans in the conference room, standing on the stage, in front of 5 other Keronians and Mois, who sit in the audience's chairs.
"You could say, singing to victory?" A tanned girl with died short blond hair added, spinning some cds with her fingers. She was dressed in a school uniform with a white shirt, a sleeveless dark blue vest over it and a gray skirt. She looked completely human, although she was yet another alien.
"That's the spirit, Lady Mois!" Keroro smiled brightly. "So, new recruit Natsumi wil be the group's female idol and will take care of this operation. I'll stay here and manage your activities. Understood, new recruit Natsumi?"
"Useless. Stupid green!" Samama shoved Keroro out of the stage, facing the platoon herself. "One - I'm a keronian now, and 'Natsumi' doesn't even sound like a keronian's name!" She stopped for a brief moment, placing her hands on her torso. "Natsumi…Summer… Sama… Call me Samama from now on!"
"Uncle!" Mois ran to Keroro, hugging him before he could even recover from the impact.
"Sama…ma?" Giroro dreamily admired her, getting some surprised glances from Dororo and Tamama.
"Anyway, now that the stupid green is out of the way, here's my proposal!"
"Wait, right there!" Keroro jumped from Mois' embrace, raising his hand to Samama. "You should just follow my plans, new recruit Natsumi! I'm the leader here!"
"So…? You're still the useless sergeant who hasn't done anything useful in years! Heh! Sergeant Major Kururu, you're smart enough to realize that he's just an obstacle to conquering Ear-… I mean, Pekopon, right?"
"I can't deny it… ku, ku, ku…"
"If that's so, take this useless guy out of here!" Samama ordered.
"What-?!" Keroro froze in place. His plan had completely backfired.
"Ku, ku, ku… I'll release you after we've conquered Pekopon, 'leader'. I press!" Kururu aimed the remote at the stunned Keroro, who immediately disappeared into a previously unseen hole, right under him.
"Sergeant!" Tamama and Mois ran to the hole, but it quickly closed.
"Don't worry about him, the leader is fine, I guess." Kururu laughed. "This is just for his own plan anyway. He's the one who had the idea of recruiting Natsumi. Ku. Ku. Ku…"
"So, now, that I'm the leader here… this is what we'll do!" Samama proclaimed, jumping to the stage.
The new Natsumi quickly explained her plan to the platoon members, who decided to accept her plan after a brief discussion.
"Lady Natsumi… You want to attack the people of this planet. Are you really sure you can do that without hurting anyone?" Dororo asked. He was certain that he just missed some detail. There's no way Natsumi would propose a plant that could hurt people, right?
"Of course… not!"
"What?"
"Kururu, now!" Samama, ordered, pointing at Dororo.
"I press!" Kururu grinned, pressing a button while another hole appeared right under Dororo, quickly closing.
"Now that we've gotten the useless guys out of the way, it's time to start!"
"Did anyone here see Natsumi?" The double doors in front of the meeting room had opened and Fuyuki stood there. He had apparently having just arrived home, still wearing a white jacket with a thick green line crossing it vertically and blue pants. His eyes quickly glued on the new Keronian. "Hey, who is that?"
"So, new leader, should we turn him into a Keronian too?" Kururu asked amusedly.
"Forget it. He'd be as useless as the stupid green. Tamama, Giroro, capture him and keep him out of the way!"
"A-Are you sure?" Giroro wondered for a moment, would she really dismiss her own brother so casually?
"Of course! Do you want to end up like the stupid green!?"
"No, understood! Sorry!" Giroro nervously complied.
"Hey, wait, corporal! What's happening here? Where's the sergeant and Natsumi!?" Fuyuki looked at the new Keronian. "What have you done to them!?"
"I was Natsumi, stupid Pekoponian, but I'm Samama now, new leader of the Keroro Platoon!"
Mois raised a green cell phone and the small object started shinning, the light continued to expand, enveloping her entire body, before quickly disappearing. Replacing the tanned girl, there was a silver haired one, with golden eyes and pale skin. Rather than a traditional Japanese school uniform, she was wearing a strange, but distinctively royal outfit: a purple breast plate, baggy white bloomers and a large purple hat which resembled a crown. Rather than a cell phone, she was holding a golden lance, which ended in one of the points with a crescent moon and in the opposite side with a metallic sculpture resembling a meteor.
Mois threw the Lucifer Spear forward just as she jumped too, grabbing it with one hand and flying across the room in a second. She grabbed Fuyuki with her free hand, quickly flying past the Keronians.
"They escaped." Kururu blankly noted.
"Whatever." Samama shrugged, afterwards drawing a large grin on her round face.
"Let's start the operation… Pekopon's last day!"
/
"What was happening there?!" Fuyuki asked Mois as they flew through the sky on her Lucifer Spear.
"Uncle used a new weapon to turn Natsumi into a Keronian."
"Are you serious? That new Keronian was my sister?!"
"Yes."
"Then, why was she acting like that?!" Fuyuki looked towards his home, confused.
"Uncle used a new weapon which changed her personality alongside with her body. It seems like the personality modification was too… drastic and she took over the platoon and intends to invade Earth… you could say, total make over!" Mois looked with worried eyes at the Hinata residence which quickly disappeared into the scenery as they got away from it. "That's not all… she even captured Uncle."
"Mois… Let's go back." Fuyuki looked at his house with determined eyes, gripping firmly the golden lance, "We've got to stop sis and save her."
"Understood!"
/
"So, this is the best robot that you mentioned before? It has already been adjusted, right?" Samama asked, looking at the giant robot that had gone basically unused up to now. In its stored form, only a giant metallic head similar to Keroro's could be seen.
"Of course!" Kururu replied with what seemed like his enthusiastic tone, raising his hand with a positive sign. "The Machine #2 is almost finished."
"With this thing, the whole city will be vaporized in an instant. As soon as the Pekoponians see their enemies, they'll into despair and give up!" Samama declared, smirking.
"Are you really going through with this, Natsumi?" Giroro asked, looking sternly at the light red Keronian.
"Natsumi! Natsumi! Could you stop that, Giroro?! I'm a Keronian now! I'm Samama! Forget my old life! Soon I'll have Pekopon in my hands, and that's what matters! Aren't you guys invaders?!"
"No one changes that fast! Will you really let some stupid gun control you, Natsumi?" Giroro said, drawing a glare from the artificial Keronian.
"Don't think you'll get some dramatic exit, Corporal!" Samama raised her right hand, pointing at him. "I'm doing this out of my own will. I'm not being controlled or influenced by anything. I just feel like showing how useless you've been all this time."
"Do whatever you want, 'Samama' ". Giroro snarled, walking away from her.
/
An explosion of orange light covered the Hinata residence. A large streak flew from it, crossing the skies like a giant pillar, before suddenly curving itself and going elsewhere.
"Are they leaving already?" Fuyuki wondered, sitting on top of the Lucifer Spear, alongside Mois.
Angol Mois turned the flying spear towards the Hinata residence abruptly. "Uncle, I'll save you!" She held firmly onto the spear. "Fuyuki, get ready! You could say, returning home! " The golden weapon rocketed with an explosion of light, crossing the sky in an instant.
/-
There were high buildings everywhere one looked, and, below them, walking through the streets, were an uncountable number of pedestrians walking back and forth, beside them there were busy streets with cars. Even though one might think so many small components would create chaos, order actually existed in that flow of people. From the skies, a bright yellow sphere suddenly appeared, its tail blazing through the air and crashing into the streets in an instant. The traffic flow suddenly stopped.
The cars were immobile, unable to drive through other vehicles. A few that couldn't stop timely just crashed into others. The people ran in a disorientated pace, forcing themselves against each other while trying to escape in opposite directions.
The blinding light disappeared, revealing a giant metallic robot. Its armor was light red, like Samama's skin, with a red mono-eye above the black mouth plate on its helmet, a red metallic sun stood as the robot's head insignia. Disproportionately large shoulder pads resembling Samama's face damaged buildings as it stood up, revealing its black inner frame through the hands and joints. It seemingly didn't carry weapons, but its mere vision was alien to every human in that city. The mechanical giant towered over smaller buildings and moved unlike anything ever seen by most humans.
Four of the keronians were inside the giant weapon, Samama, Tamama, Giroro and Kururu, in a large collective cockpit, each one surrounded by several control panels and monitors. A large central screen positioned in front of Samama's seat showed the view of the main camera, the confused city below.
"Is everything prepared, Sergeant Major Kururu?" Samama ordered.
"Ku! Ku! Ku! The space-time eraser is ready, new leader." Kururu began tipping furiously, configuring the attack. "Range?"
"Well, then… Destroy the entire city!" Samama grinned. This was just too easy.
Giroro sternly looked at the person formerly known as Natsumi. He could still see her fire burning in that body, but, still, her personality had been warped beyond any recognition. Stupid Keroro, that was his fault, no one else's. "Even if we win like this… Natsumi…"
Tamama just observed the situation silently. Natsumi seemingly would do everything much faster than Keroro. A direct strike with a super weapon, simple but effective. Maybe she should become his new idol? No, he wouldn't just forget his loved sergeant like that! Or would he?
/
The Keronian ninja, Dororo, emerged from a cloud of smoke, quickly followed by his leader. The smoke dissipated, revealing an expansive room, with desks and computers in one side, along with a screen large enough to cover an entire wall behind those. Everything was deactivated, and the two Keronians soon found out that every control had been locked.
"She really learned fast… Lady Natsumi…" The green frog looked down for a moment, uncharacteristically thoughtful. Was he really such a bad leader? Should he just settle down and let Natsumi finish everything?
"Leader, there's someone coming!" Dororo said, while brandishing his small sword. The sound of soft impacts on the metallic floor easily echoed through the vast chambers in their base.
"Is-Is it Samama already?" Keroro's legs were trembling, while he tried vainly to hide himself behind Dororo. The keronian ninja focused on the main door, in the opposite side of the room, which slowly slid open.
"Sergeant?!"
"Uncle!"
Keroro excitedly jumped towards them, using Dororo's head as a springboard. "Lord Fuyuki! Lady Mois!"
"You're alright!" The three said in unison, feeling completely restored for the moment while Keroro hugged them.
"It's good to see everyone is doing fine…" A fifth voice popped up in the room – suddenly, there was a tanned teen with gray hair standing in the middle of the command center. He had a confident smile, while holding a yellow pen, contrasting with his black jacket and brown pants. Smirking confidently, he pointed at Keroro with his pen. "Don't you think there's still a big problem out there?"
/
The robot raised its hand to the sun plate on its head, pointing at it with one finger. "Hyper Beam!" Samama yelled from the cockpit, thrusting forward two control sticks. The robot answered the command, releasing a red beam from its forehead, which expanded as it got further away from the core, engulfing more and more of the city. Everything under the ray of light disappeared immediately, not even dust was left behind, a large wasteland suddenly appearing among the buildings.
Giroro looked at Samama, noticing no hesitation from her. "Natsumi wouldn't have done this… Damn it… But, it's for Pekopon's invasion." The red keronian clenched his hands, glaring at the self proclaimed leader of the platoon.
"Alright, let's finish it!" Samama crossed her arms, "Now, use all time-space beams at once!" The robot mimicked its main pilot, crossing it arms, and soon floated to the sky, standing miles above the ground. "A single shot, and the first step in Pekopon's invasion will be complete!"
The gargantuan robot lowered its hands, the front of its fingers opening to reveal cannons in each one. Simultaneously, the metallic sun and the canons started shinning again. "Fire!"
/
Standing in a large hangar, Keroro carefully inspected what looked like a plastic toy gun. Mois, Fuyuki and Saburo were standing there alongside him.
"Hey, sergeant, that's the weapon that could turn animals into humans?"
"You're correct, lord Fuyuki! This isn't as good as Kururu's new weapon, but we should be able to make Natsumi go back to normal." Keroro suddenly waved the weapon, dropping it, but Fuyuki threw himself at the ground, holding it with a sigh.
"By the way, Keroro, where is the giant robot you had mentioned? This hangar is empty." Saburo wondered
"Don't worry about it! Lance Corporal Dororo is bringing it."
"Dororo is… bringing it…? What do you mean Sergeant?" Fuyuki asked, still holding the weapon in his hand.
A blur appeared out of nowhere, quickly traveling to the middle of the hangar, standing among the group. "Leader, I've arrived. Here they are." Dororo held four objects that resembled small plastic balls, each one divided in white and red sections.
"Very good, Lance Corporal Dororo! Now, let me, Sergeant Keroro, handle this!" Keroro shoved Dororo out of the way, giving each one of the colored balls to the teens standing around him, and keeping one to himself. "With these spheres, we can summon the Kerodeen Z, the robot Kururu built after the incident with Kiruru last Christmas. Because the other members of the platoon aren't here, you'll help me control it this time!"
"Bu-Bu-but… I'm right here, Keroro…"
Saburo glanced at Dororo's negative aura, before quickly focusing on the sphere Keroro had given him. Kururu might be one of the only ones he could genuinely call a "friend", but he just couldn't let him conquer Earth like that. "Ok, Keroro."
"Did you get it? Very well, let's go!" Keroro jumped onto a crate, raising his first towards the ceiling. "Kerodeen Z!" Quickly, the four spheres turned into light, along with the ones holding them. The light flew through the hangar's ceiling, getting to the open sky and combining into a single, brighter sphere.
/-
"A high speed object is quickly approaching!" Tamama yelled, his pupils suddenly contracting almost unnaturally as he stared angrily at the monitor.
"Eh…? The Pekoponians detected us that quickly?" Samama asked innocently, leaning on her chair.
"That's too fast for a Pekoponian airplane… ku, ku, ku…" Kururu grinned. "It seems things will get interesting…"
The object abruptly stopped, and, with a thunderous roar, the clouds surrounding it vanished, revealing its form. It was another giant humanoid robot, this one with dark green armor covering the gray frame. Its face was gray, with yellow eyes and a mouth plate with several openings, smoke coming from those holes. Covering its chest, there was a red star. Extending from its back, there were red metalic devil wings. Its eyes shinned with a yellow light, glaring at its opponent.
"So, New Recruit Samama, do you really think you can defeat me, Sergeant Keroro?" Keroro's face popped up in a window in the main screen of the Invader Machine's cockpit.
"Of course, stupid green." Samama nodded and pushed a handle, firing the Hyper Beam again. The ray just scathed the Kerodeen's left arm, but that was enough to make the arm completely disappear.
"Wha-What?!" Keroro looked at a monitor beside him, noticing the damage.
"The left arm has completely disappeared, but there has been no damage to the other components, you could say, perfect cleaning?" Mois noted.
"Keroro, grab that robot and let me handle this." Mutsumi said, leaving the robot's cockpit.
"Wait! Without four pilots our fighting capability will drop!"
"Just hold on a little longer." Saburo winked, only to vanish through a door no one had noticed before.
"If there's no other way… take this! Keron Punch!" The Kerodeen Z thrust upwards, dodging a second Hyper Beam, meanwhile, its remaining fist detached from the body, flying right into the Invader Machine #2's chest, sending it towards the ground, below the clouds, the Kerodeen soon following it, recombining with the arm.
Fuyuki's hands trembled when he noticed the wasteland lying under him. There were no signs of a city, or even any life, at all. Only dust of a desert extending to the horizon. "Natsumi… Natsumi did this…"
"Now, prepare for my final attack, the Keron Voice!" Keroro yelled loudly while the Kerodeen grabbed the invader machine with its remaining hand, crashing with it on the ground.
"Hit by the stupid green! Kururu, what is this Keron Voice?" Samama punched a control panel, glaring at her yellow Keronian sitting next to her.
Kururu just grinned.
"Quick! They'll probably fire at any moment!"
"Heh." Kururu shrugged, "I have no idea. I didn't install anything like that on the robot."
"A secret weapon?! That Keroro…" Giroro sweated nervously. Why was Keroro always so efficient while trying to save Pekopon but always failed when the matter was actually invading?!
"Alright, here it goes!" Keroro's voice echoed through the speakers, while still trying to hold the Invader Machine #2 with a single arm. "This is… the Keron Voice!"
"Here it comes!" Giroro jumped from his seat, to stand in front of Samama.
"Gi-giroro…?" Samama stuttered for a moment, looking at him perplexedly.
"Sergeant, I don't want to die!" Tamama helplessly burst into tears.
"Keron, keron, keron, iron cyclone!
Keron, keron, keron, iron cyclone!"
A music invaded their speakers and the keronians just listened to it, dumbfounded.
"That's his secret weapon…" Samama twitched. "STUPID FROG, I'll just kill you now!"
"Stupid frog…?" Giroro muttered lowly.
The Invader Machine ripped apart the other arm of the Kerodeen with its own hands, afterwards punching it into the ground, its mono eye glowing with an ominous red light.
"The sergeant asked for it." Tamama noted, while Kururu just laughed.
"Hi, guys, it seems you're having fun, eh?" Saburo entered in the collective cockpit, through a door no one had noticed before. "Is that pink Keronian Natsumi? You look really cute like that."
"Sa-saburo?" Samama turned from the monitors, looking behind her seat, blushing. Her expression quickly changed into anger, when she noticed that Saburo was holding a keronian gun. "You think I'm going to fall for that?!"
"Natsumi, stay still!" Giroro yelled, while grabbing her with all his strength. "That's the 'we all live together' gun, right? Do it!"
"Eh? This was easier than I thought it'd be. Sorry, Kururu, but this is game over." Saburo smiled confidently.
"Whatever." Kururu placed his arms behind his back and leaned on the chair.
"Here it goes, Natsumi!" Saburo raised his weapon, aiming it right at the pink Keronian that desperately tried to break free from Giroro. He shot a white beam, electric sparks flying from the weapon. The projectile instantly hit Samama, showering her under a white light. She seemed surprised in a second, but, in the next one, fell to the floor with empty eyes, still as a Keronian.
Giroro and Saburo looked apprehensively at the unconscious Keronian. "Hey, Kururu, what is this about?! She should have returned to human form, right?!" Giroro yelled.
"Heh- I guess the old weapon just wasn't strong enough to finish the job. Don't worry, she's fine."
"Whe-where is this?" Samama slowly rose up, holding onto a nearby seat to stand up. She looked at her own hands, "I… I remember now…"
"The game's really finished now, too bad. I press!" Kururu pressed a red button, suddenly green sparkles appeared everywhere around the damaged robots. Slowly, people and buildings faded back to reality, as did the Kerodeen's missing arm.
"He did it!" Fuyuki commemorated together with Keroro, jumping around the control room of the robot.
"You could say, happy ending!" Mois exclaimed, smiling brightly this time.
Suddenly, a black blur crashed into the robot's cockpit. The mysterious form rose, assuming a small humanoid shape. With its red eyes overflowing with rage, it said "There won't be any happy ending for you, STUPID FROG!"
Samama suddenly jumped onto the green frog, holding his neck and swinging him back and forth "Give me back my body! I don't want to be a stupid frog forever!"
"Natsumi!" Fuyuki jumped on his sister, hugging her strongly and smiling with a genuinely happy face.
"Fu-Fuyuki?"
"It's great to have you back, Natsumi!"

The birds were singing, and the sun shinning over the Hinata residence… Peace seemed to have returned to Earth, or had it?
"You're kidding, right?" Samama was stretching the skin of Kururu's face "Tell me I'm not really stuck like this?!"
"Heh. It seems there was an unforeseen glitch in the interaction of the two transforming weapons. Don't worry, I'll fix this… someday… Ku, ku, ku…"
"Someday?" Samama outlined a weak smile, which broke quickly.
"Don't worry, Natsumi, living as a keronian isn't bad." Dororo tried to calm her, but just froze when he felt her anger.
"Someday…"
Tamama just ate his snacks, not actually paying much attention to anything.
"Someday… Someday isn't soon enough, STUPID FROG!" The beast with a dark body and flaming eyes jumped towards Keroro again.
"Wa-Wait, Lady Natsumi! I-If you fight here you might break the weapons!"
"Who cares about that useless trash?!" Natsumi shouted angrily, grabbing the green keronian and throwing him right into Kururu.
"GEROOO!" Keroro's body knocked down Kururu, falling over the new transforming gun and crushing it in pieces. Sparks flew from the weapon, which started shinning strongly. The light expanded, covering the entire room with a sphere of light.

Notes:
Kerodeen Z – A new giant robot briefly shown in episode 247 of the anime, although its front side was never shown because Momoka preferred to record Fuyuki rather than the giant robot battle. Its general design and silhouette looked like the titular robot of the anime "Raideen", however its weapons and red wings were seemingly based on the Mazinger Z. The name makes a reference to both.
Samama – Natsumi's Keronian form featured in this chapter, "Samama" is actually an official design, a Keronian based on Natsumi, who appeared in the magazine Keroro Land, as one of the fan drawings chosen to be redesigned by Yoshizaki Mine.
Each Keroro Land features 3 new Keronians, but they're just designs with a little comment from Yoshizaki Mine attached, usually they have no storyline at all. Several Keroro Land original Keronians ended up appearing in the anime later on and getting stories, like Joriri and the entire Shurara Corps, but many also didn't, like Samama.
The annotations in the original fan drawing say that she's created from Natsumi's DNA, but the fan design isn't exactly identical to the official one, name aside. Because she has no official storyline, in neither anime or manga, I just used her in this story as Natsumi's Keronian form.
