    Keroro Platoon 

Sergeant Keroro

Voiced by Mugiwara Yoshi

In the Abridged series, Keroro is a useless, self-absorbed Jerk Ass who can't accomplish anything (big shocker, right?). He occasionally makes an effort to come up with an invasion plan, but sadly his plans wouldn't make sense to a two-year old. Has a fear of being useful, is in a relationship with subordinate Tamama, and is apparently Hispanic. The entire series revolves around his friends and peers wanting to kill him because they hate him so much.
  • Ambiguously Gay: Averted in the early episodes. As soon as he makes a pass at Tamama when the character is introduced, he outright says "I'm gay! The end!". Also inverted, because he seems to have an attraction to women but won't come forward about it like he will his attraction to Tamama. Subverted by Episode 11, where he comes to grips with his sexuality and decides he is Bi. Doesn't stop his relationship with Tamama from getting any worse.
  • Gratuitous Spanish: Due to his voice actor being Dominican.
  • Jerk Ass: Up to Eleven and exaggerated in many ways. Keroro is a terrible person who treats people horribly for his own amusement, is afraid of being useful in any capacity, and sees all of his life's problems as being Never My Fault. The Myth Arc of the series is people hating and wanting to kill him either for this or his uselessness. The end of Season 2 through Season 3 is based around pulling him out of this state into someone who is capable of thinking of others.
  • Lovable Sex Maniac
  • Idiot Hero
  • Mike Nelson, Destroyer of Worlds: Despite being an invader by (failed) profession, his only real successful destruction of life was an accident.
  • The Neidermeyer: His platoon might hate him even more than the original series' counterparts.
  • Politically Incorrect Hero: Played With, depending on the situation.
  • The Protagonist: He's the lead character and goes through development throughout the series, though it doesn't always make him better.
  • Small Name, Big Ego: Whereas his original series counterpart is at least a celebrity on Keron, everyone hates this Keroro, yet his ego is still enormous.
  • Unsympathetic Comedy Protagonist

Private Tamama

Voiced by ThornBrain

Tamama is Keroro's adorable boyfriend, until he is revealed to be a "she" at the end of Season 1. Tends to act stupid like the rest of the platoon, but occasionally exhibits rational thought.

Corporal Giroro

Voiced by ThornBrain

Giroro is Keroro and Dororo's lifelong friend, though he is less than pleased with Keroro's failures and would like their platoon to successfully invade Earth. Had a transparent crush on Natsumi until getting together with and eventually marrying Dororo, and is a transvestite. After the wedding, Giroro no longer wants to invade Earth, and instead just wants to live a peaceful life.

Lance Corporal Dororo

Voiced by ThornBrain

After being stranded in the forest with a broken leg, the lonely, depressed, mentally damaged, socially awkward, unpopular rich kid Dororo became a ninja. He appears to have a form of Stockholm Syndrome in relation to Keroro and Giroro, but his only true friends may indeed by Giroro and Koyuki; nobody else seems to care about him. By Season 2, heaps of Character Development has led him to not take Keroro's crap so much anymore and settle into a happy relationship with Giroro.

  • BFS: His Giant Ninja Fuck-You Star, which he had to meditate for two episodes to learn how to use. The first two times he uses it fail catastrophically. The third time, while he's in a combat high, works like a charm.
  • Breakout Character: Even Yoshi didn't care about him until they finally introduced him. He almost immediately became a fan and creator favourite, and he was voted Travis, Yoshi and Thorn's favourite and best-developed character at the end of the second season.
  • British Accents: Has a slight British tint to mirror his posh upbringing and to differentiate him from Thorn's other voices.
  • Butt Monkey: His role as forgotten Butt Monkey in the original is replaced with that of a directly/emotionally-abused punching bag.
  • Catch Phrase: "I'm lonely" and "(X) makes me lonely". Doesn't speak it directly much after Season 1, though it has been referenced in places.
  • Cloud Cuckoolander: Perhaps downright mentally disturbed.
  • Country Matters: Uses the c-word in his character song "The Lonely Dance".
  • Deuteragonist: Develops the most out of all the cast, and is nearly as much the focus as Keroro.
  • Happily Married: He and Giroro as of Episode 15.
  • Hilariously Abusive Childhood: And like any good Abridged Series, it's taken Up to Eleven and beyond.
  • Ill Boy: Taken to a ridiculous extreme come Episode 11. According to Pururu, Dororo has every virus, germ, parasite, cancer, and other diseases in his body, some of which are female-exclusive. They're all dormant, completely benign, and non-contagious. Of course, come the next few episodes, it's pretty clear they're not fully dormant or non-contagious, but they also don't function like normal diseases.
  • Malicious Misnaming: The longest running gag of the series. Characters often switch his name with something starting with D (Doorknob, Dorito) or something completely random (Laryngitis, Hangnail).
  • Momma's Boy: Suggested in flashback episodes of Season 1 but subverted in Episode 10, where he reveals resentment towards his mother. He is very uneasy about seeing her again in Episode 19.
  • Oblivious to Love: Koyuki sees him as a good friend, but for the most part he seems oblivious and just wants his platoon to be his friends (which he actually did accomplish with Giroro; then they kept going).
  • Straight Gay: Ask GiroDoro SFA confirms him as the only conclusively gay character.
  • Straight Man: After getting over his family and friendship issues, and settling into a happy relationship with Giroro, he develops into this from late-Season 2 onward.
  • Took a Level in Badass: While always physically capable thanks to the instincts he developed by Keroro and Giroro's childhood abuse, most of the series is written at his expense. He is finally able to put his skills to use and come into his own as a powerful hero in Season 3, namely against Robobo.
  • Worthy Opponent: Pururu sets him up as being indestructible, and Zoruru challenges him to a fight to prove it wrong. In his own weird way, Dororo proves himself to be this.

Sergeant Major Kululu

Voiced by InfamousGentleman

The biggest personality reversal from the original Keroro Gunsou. Kululu isn't the transparently scheming, constantly-giggling Token Evil Teammate like his counterpart, but is rather an understated, keeps-to-himself, sarcastic, apathetic Jerk Ass.

  • Brilliant, but Lazy: Kululu has the skills and resources to build large mechs for the platoon's use or to tape a whole planet back together, but he rarely ever does anything. It takes him three hours to build a drill when he had thirty minutes, yet it takes him mere minutes to cannibalize Shurara's mech for the platoon's own personal Gundam. After the events of Season 1, the platoon are mostly glad that Kululu keeps to himself and stays out of the way.
  • Cloud Cuckoolander: And aware of it.
  • Jerk Ass
  • Start of Darkness: Discussed in Episode 12, as the team are in fear of him turning into Future Kululu. Ultimately averted, as he turns out to be pretty mellow about the team.
  • Token Evil Teammate: Subverted. Throughout the first season he's about as blatant as his main series counterpart. However it was mostly his future doppelganger. The real Kululu returns at the beginning of Season 2, and he mellows out considerably.
  • Troll: He once trolled a leading economic power and the leaders of the world at once, and he collapsed all of Uganda with porn.
  • Un Evil Laugh: Has switched out to the much less menacing, much more nasally "HEGH!"

Angol Mois

Voiced by codeblackhayate

Mois is a sweet alien girl with a big crush on her longtime family friend Keroro. As opposed to the original Mois, this character accomplished her mission to destroy the world. She now just hangs out with the platoon and doesn't do much of anything.

    Humans 

Fuyuki Hinata

Voiced by ThornBrain

The scatterbrained and fairly stupid brother of Natsumi and son of Aki. Keroro may be his only friend, and by the end of Season 2 he is definitely Keroro's only friend.

Natsumi Hinata

Voiced by LillyLivers

The girl of the house who is less than amused by the Keronians, and one of the more capable and sane members of the cast. She is the center of attention at her school by all of the females, and she wishes she could just have a friend instead of an admirer.

Aki Hinata

Voiced by LillyLivers

The mom. She is a manga editor who is so desperate for ideas that she will take anything.

Koyuki Azumaya

Voiced by Revy Moonshine (Episode 4-18), Thaichestnuts (Episode 22-present)

A cheerful ninja girl with a crush on Natsumi. One of Dororo's few real friends (and Natsumi's for that matter).

  • Action Girl
  • Cloud Cuckoolander
  • The Cutie: Emphasized more starting with Episode 10
  • Dogged Nice Girl: Her to Natsumi in Seasons 1 and 2. Natsumi only wants her as a friend. They finally start a relationship in the Season 2 finale.
  • School Girl Lesbians: Subverted, as Natsumi has no interest in being anything other than friends. Double Subverted in the Season 2 finale: Natsumi finally says they should go for it.

Momoka Nishizawa

Voiced by Dobuchu

Fuyuki's secret admirer with an extreme split personality.

Paul Moriyama

Voiced by BigTUnit1

Momoka's butler and enabler of the impossible. He can do anything without trying, regardless of the laws of physics, though the most he does is cause explosions by moving.

  • Expy: Paul is the equivalent of the Chuck Norris meme. His voice is also based on Patrick Stewart's, and Travis gets into the voice by saying "Commander Worf's head looks like a fanny".
  • Memetic Badass: Invoked a'la the Chuck Norris meme.
    "Hello, Karate Butler Paul at your service. Would you like a cup of tea? I can brew it with my bare hands. Or maybe you’d rather a slice of cake? I can bake a cake just by looking at it."
  • Stuff Blowing Up: His powers mostly manifest in causing things to explode, just by moving his body.
  • Suspiciously Similar Substitute: Parodied with Paul's Puppet Momoka, which he uses after her death to keep people from knowing she's dead so that he can keep his job.
  • Take That: His Puppet Momoka actively mocks Momoka's angry personality.

Mutsumi Saburo

Natsumi's secret crush. He has a radio show, despite being mute, or at least unable to say a single word without being interrupted.

    Other Recurring Characters 

Narrator/ThornBrain

Writer ThornBrain occasionally acts as the disembodied voice that details the setting of a scene and makes sarcastic remarks. His role as narrator is considerably smaller than the Sgt. Frog counterpart, and he rarely shows up after Season 1.

Viper

Voiced by BigTUnit1

Viper is a half-snake, half-humanoid space pirate whose Tangled Family Tree serves as a major plot driver for most of the series. His initial appearance in Episode 4 suggests he has a history with the Keroro Platoon, and Episode 7 reveals that he's Dororo's dad; Dororo's multitude of issues can be traced back to Viper. Episode 18 reveals that he is also Keroro's father, and many of his issues can also be traced to Viper. After Season 2, Viper takes the effort to connect with his sons more.

  • Heel-Face Turn: Appears in Episode 4 as a villain and kidnaps Dororo and Koyuki. By Episode 18 he's on friendly terms with the platoon.
  • Luke, I Am Your Father:
    • Averted at first with Dororo. The characters just seem to know Viper's Dororo's father already.
    • Subverted after Season 1, as Dororo isn't sure if Viper is his biological father when he grows up. Double subverted by the end of the second season where, despite the father debate never being settled, Dororo is at least well-adjusted enough to not be burdened by the issue any longer. As such, Viper is simply accepted as his father.
    • An additional subversion occurs in the Season 2 finale: he is revealed to also be Keroro's father, and both Viper and Dororo know this. However Keroro, despite laying out all of the hints himself, is too stupid to put all of the pieces together, so there is never a big reveal until Keroro appears in the Q&A blog.
  • Really Gets Around: The list of his children is constantly growing.
  • Tangled Family Tree: It seems straightforward at first: Viper, his father, his wife, their sons. But then in Episode 19 we meet his "Mom-Son" and "Dad-Train"...

Future Kululu

Voiced by InfamousGentleman

Kululu's future self. He is apparently the Kululu seen from Episode 6 through Episode 10, and the present-day Kululu is trapped in a box labelled "HAMDINGERS" in the meantime. Kululu turns into him at the end of Season 2, then back to normal in Reset.

HQ

Voiced by Jiggly Jacob

An unnamed Admiral (demoted to Captain in Season 3) in the Keron Army with a lethal loathing of the Keroro Platoon. He dumps the platoon on Earth to get rid of them, only to send people and weapons after them to kill them. Generally speaks in a bored monotone.

  • The Antagonist: For all of Seasons 1 and 2, and returns to this spot for Episode 23.
  • Bad Boss
  • Big Bad: For all of Seasons 1 and 2.
  • Driven to Suicide: In Episode 16, Kilili hits HQ with all of his stored negative energy, severely depressing him. Everyone in the universe commits suicide shortly after. The suicide is undone in Reset.
  • Dull Surprise: His usual speaking voice. You get the sense that he's not crazy about his job. He gets more energy from constant coffee drinking for his return in Episode 22.
  • Jerkass: He dumped the platoon on Earth with the implication that he just wanted them out of the way. He never made clear that they still had an invasion mission, and now he's trying to kill them for wasting time doing nothing.
  • Must Have Caffeine: Drinking coffee is part of his job description, but it's not very good coffee. Keroro teaches him how to make good coffee in SFA: Reset, and the next time we see him he's drunk so much of it that he's been awake for four straight months, been demoted from Admiral to Captain, and talks to his empty coffee cups like they're his subordinates.
  • The Voice: Until Episode 22, he's never seen; only heard over intercoms, answering machines, or while having a monologue to a black screen.

Chief Medic Pururu

Voiced by LillyLivers

A childhood friend of Keroro, Giroro and Dororo with something of a loony streak. Arrives out of nowhere to give the platoon checkups, which is just a cover for her to find out the platoon's weaknesses.

  • A Degree in Useless: Word Of God says she got her medical degree in the Keron equivalent of Coney Island, which her voice actor LillyLivers describes as the "most backwards fucking place in the world". Her completely wrong diagnoses of the platoon confirm that in-universe.
  • American Accents: Sports a Brooklyn accent.
  • Cloud Cuckoolander: Most obvious as a kid. She seems fairly focused as an adult, but still has moments where her warped mind is noticeable.
  • Cute and Psycho: Attractive and pleasant; secretly harvesting organs for cash.
  • Distaff Counterpart: To Keroro in many ways, including having a casual approach to sex and sexuality, being pretty rubbish at her job, and having her own "Serious Pururu" moment (as in "I'm so serious, even the jokes I tell are serious" Pururu).
  • The Ditz: As a child, she doesn't seem aware of her surroundings or make clear conversation.
  • Hilariously Abusive Childhood
    "When my mommy drinks juice, nobody's happy."
  • The Mole: She's really there to learn the platoon's weaknesses and relay them to Garuru.
  • Sticky Fingers: She reveals in her Season 2 finale reappearance that she's been pickpocketing the time-locked populace and shoplifting stores. In the audio blog, Giroro and Dororo reveal that she also stole a house.

Solid Snake

Voiced by ThornBrain

The main character of the Metal Gear games makes recurring cameos to reference said series. He mostly appeared as a recurring One-Liner gag, but became an actual in-universe entity in Episode 7.

Raiden

Voiced by BigTUnit1

The fellow main character of the Metal Gear games has also started appearing in Season 2. He does not reference MGS so much as act like a walking metrosexual Facebook/Twitter feed.

  • The Ditz
  • Duel to the Death: With Snake in the series finale. According to the credits, both lost. They're both back to life in Reset.
  • Small Name, Big Ego: He thinks he rocks. Almost no characters are aware of his presence.

Ocelot

MGS3 Young Ocelot - Voiced by Xcaliborg (Episode 19), BigTUnit1 (Episode 22)

MGSV Revolver Ocelot - Voiced by Jiggly Jacob (Episode 24)

Ocelot starts appearing in Season 3, at first as his Metal Gear Solid 3: Snake Eater version, and then getting progressively older. Starting with Episode 22 he quotes various strange things Jiggly Jacob has said.

  • Shout-Out: His lines in Episodes 22 and 24 are quotes from one of Jiggly Jacob's Sims 4 videos.

    Garuru Platoon 

Lieutenant Garuru

Voiced by BigTUnit1

The ridiculously friendly, yet surprisingly dangerous, commanding officer of the Garuru Platoon and the older brother of Giroro. He is under the illusion that Keroro is a military genius when he's really a complete idiot, and thus anything Keroro does is mistaken for a brilliant strategy. He and his platoon are sent to Earth to finish off the Keroro Platoon in the event that the Kiruru from Episode 16 did not kill them all.

  • The Ace
  • Affably Evil: Up to Eleven. He's so nice, it drives Giroro insane. Ultimately subverted: he was overly polite in regards to Giroro because he didn't want to make his brother feel bad about all of his faults.
    "You have a lot of them".
  • Arc Villain
  • The Comically Serious: The one time he says anything remotely silly (E.G. "Well that was wacky"), he's completely deadpan.
  • Defeat Means Friendship: Implied at the end of Episode 18, and Word Of God states this was the intention.
  • Dropped a Bridge on Him: His ship unceremoniously explodes. This is undone in Reset.
  • Evil Counterpart: To Giroro, though mostly as a result of Protagonist-Centered Morality.
  • Knight of Cerebus: The mood and dialogue take a much darker turn when he and his platoon arrive.
  • Large Ham: Garuru loves the sound of his own voice, which is almost always oozing drama.
  • Nice Guy: Or as his brother puts it:
    Giroro: "Warm-hearted bastard!"
  • So Proud of You: To Giroro, but mostly for mundane things from years back such as teaching him how to read. He is also aware that Giroro is a failed soldier, but he is convinced that his brother has survived thus far because of whatever skills he learned anyway. Reset also shows that, despite his niceness being exaggerated for the sake of Giroro's self esteem, his pride in Giroro is completely genuine.
  • Villainous Breakdown: He mistakes everything Keroro does as a genius maneuver, causing him to have a few mental battles with himself over it (and lose). By the end he finally snaps and just orders his platoon to attack.
  • Worthy Opponent: To Giroro. Seems to think Keroro is this when he's really a complete idiot.

Lance Corporal Zoruru

Voiced by ThornBrain

The Garuru Platoon's half-cyborg assassin who kills by using a blade hidden in his robotic arm and speaks in a sneering whisper through a speaker. Being the cold-blooded opposite of Dororo, he is convinced that everyone wants to be his friend and that no one will leave him alone. He has heard rumours that Dororo is indestructible and wishes to prove them wrong.

  • Ax-Crazy
  • Cloud Cuckoolander: Is paranoid that everyone wants to be his friend.
  • Defeat Equals Friendship: Played with. He never fights Dororo, but Dororo mistaking him for Robocop is enough to convince Zoruru that someone out there doesn't know about him. He leaves very happy, and as with Garuru, it is implied that he is on good terms with the Keroro Platoon afterward.
  • Dropped a Bridge on Him: His ship unceremoniously explodes. This is undone in Reset.
  • Evil Counterpart: To Dororo, even in personality: where Dororo used to feel lonely despite often being with friends, Zoruru is paranoid that people won't leave him alone and all want to befriend him, despite him usually working alone.
  • Evil Laugh: Gives a low, quiet one before killing Saburo.
  • Harmless Villain: His introduction marks the first aversion of this trope in the series.
  • Knight of Cerebus: He kills Koyuki after his very first line. Practically every paranoia-drenched scene after subverts this.
  • The Lancer: To Garuru.
  • No Mouth: Talks through a speaker.
  • Worthy Opponent: Wishes to prove that Dororo is not this. In his own weird way, it turns out he was.

Private Taruru

Voiced by LillyLivers

The Garuru Platoon's frontline soldier who went to boot camp with Tamama and apparently drove her crazy.

  • Cheerful Child: Despite looking physically matured, he is played as a child.
  • Cloud Cuckoolander: Blissfully unaware that Tamama is very much not his "mentor" and was actively trying to kill him to get rid of him.
  • Dropped a Bridge on Him: His ship unceremoniously explodes. This is undone in Reset.
  • Eye Beams: His one-time method of attack.
  • Harmless Villain: The only reason he defeated Tamama was because Tamama defeated herself, and she redirects that power properly the next time they meet. The one time he does an attack, he apparently hurts himself.

Recruit Tororo

Voiced by BigTUnit1

The hyperactive techie of the Garuru Platoon, Kululu's son, and a big fan of Mint's Hints. He spends his time hacking Kululu's system and laughing maniacally for no reason.

    Shurara Corps 

Shurara

Voiced by ThornBrain

Leader and namesake of the Shurara Corps, and yet another person with a big grudge on Keroro. He has a flair for drama, a very literal mind, and is highly abusive of his own Corps. He is revealed to be yet another child of Viper, his mother is Joriri, and a lifetime of taking Joriri's advice and being ignored by Joriri drove him insane. He and Keroro reconcile at the end of the series.

  • Art Shift: Underneath his helmet is a realistic snake head.
  • Bad Boss: He abuses and intimidates his subordinates, particularly the meek Nuii, and he reveals he kidnapped most of them.
  • Berserk Button: Don't talk about how bad your life is, especially if you're Keroro. Shurara will respond with a furious rant and a relentless pummeling.
  • Big Bad: For Season 3.
  • Captain Ersatz: His personality takes many cues from Invader Zim, Handsome Jack and Dr. Squid.
  • Chewing the Scenery: A large amount for a man with his head always in a helmet. Shurara is one of the most dramatic characters in the series who speaks with lots of enunciation and, as his Villainous Breakdown takes hold, righteous, furious screaming. Once his helmet comes off, he's completely calm and collected.
  • Cold Ham: Much of his hammy Jerk Ass behaviour early on is spoken with complete calm.
  • Easily Forgiven: Due to Keroro seeing all of his own bad traits in Shurara, he lets Shurara off with "only two or three hard feelings", and they both agree to come out of the ordeal for the better.
  • Evil Is Hammy
  • Evil Laugh: Lets one out in Episode 25 before immediately saying to "Stop laughing!!!" As the episode progresses, his laughter changes from a signal of villainy to a gauge of his Villainous Breakdown.
  • Freudian Excuse: His father is Viper, who left him to his mother, Joriri. This, taking Joriri's advice his whole life, and Joriri leaving him alone to go hang out with Keroro, made him go insane. He now sees Keroro as the root of all of his misery.
  • Giant Mecha: Uses a revived Big Robobo called Shurobobo as his personal mecha when fighting the Keroro Platoon.
  • Hearing Voices: The advice of his mother Joriri continues to swirl around in his head, influencing his actions a'la Norman Bates and his mother from Psycho.
  • Hidden Depths: Genuinely misses Mekeke after he's killed in action.
  • Inferiority Superiority Complex: Acts proud and mighty, while underneath he's drowning in self-loathing.
  • Jerkass
  • Killed Off for Real: A special aversion in the Shurara Corps, alongside Kagege. Most other members either died during the course of the season (E.G.: Putata, Mekeke, Nuii) or were dead and resurrected in their backstories (E.G.: Dokuku, Giruru, Robobo). Shurara survives the whole season.
  • Large Ham
  • Laughing Mad: The more cacophonous his laughter, the more insane he's becoming.
  • Literal-Minded: Stock phrases such as "give them no quarter", "I assume you are the one behind this", and "shower me in your reverence" take on different meanings in Shurara's mind.
  • Not So Different: Keroro realizes that Shurara's faults are the same as his, and the real cause of all of his problems is simply being a terrible person. This makes Shurara transform into a being of pure self-loathing, but the platoon rescue him, and they reconcile at the end, both agreeing to come out of the ordeal for the better.
  • Revenge: He sees Keroro as the root of his life of misery. His mother, Joriri, gave him obscure advice his whole life which, after being abandoned by Joriri to go hang out with Keroro, he interpreted as a mission to kill Keroro. This was compounded with Viper reconnecting with Keroro but continuing to not know or care about Shurara.
  • Pre Ass Kicking One Liner: "Mother's orders."
  • Schoolyard Bully All Grown Up: Much of his abuse of Nuii is childish, hinting back to her being his doll in his childhood.
  • Spikes of Villainy: Has a javelin for a hand and a helmet with horns and side axe blades.
  • Suddenly Shouting: One of his intimidation tactics used on his corps.
    Gyororo: "Sir! Something weird's going on with the platoon now. There's some kind of power struggle with one of their captains."
    Shurara: "Well then good thing you're here! 'Cause if you weren't I could actually SEE IT! GO!"
  • Tranquil Fury: While he spends most of his fight yelling in anger, he drops to an eerie calm as he hears Joriri tell him to kill Keroro, delivering the final blow.
  • "Well Done, Son!" Guy: He is angry that Joriri left him to spend time with Keroro, and that Viper was happy to reconnect with Keroro in adulthood but continued to not know or care about Shurara.
  • Villainous Breakdown: Becomes increasingly furious and unhinged as the season progresses and more of his Corps die to the Keroro platoon. When he becomes directly involved in Episode 25, he drops all pretense of being cool and threatening, instead letting out all of his hatred and madness in the platoon's direction.

Nuii

Voiced by King Theo (Reset-Episode 20), Thaichestnuts (Episode 22-Episode 24)

A meek Keronian-shaped doll who can transform herself and anyone around her into teddies. She was Shurara's doll as a child, and she is the subject of most of his abuse.

  • Anti-Villain: Doesn't want to hurt anyone, but is forced to out of both fear and loyalty to Shurara.
  • Apologetic Attacker: Shurara forces her to take out the platoon, and she apologizes profusely while doing so.
  • Apologizes a Lot: Shurara's abuse makes her instinctively apologize for anything that could be seen as a mistake.
  • Baleful Polymorph: Her special power is to transform living people into teddy bear versions of themselves.
  • Because You Were Nice to Me: Natsumi's kindness convinces her to turn on Shurara and stop Gyororo.
  • Becoming the Mask: She pretends to be Natsumi's teddy bear, and Natsumi's love and kindness reminds her of Shurara's childhood love. She implies her feelings of wishing to stay with Natsumi while still in disguise.
  • Dropped a Bridge on Him: Episode 24 ends with her flying directly into Todd Sirkowski's hot air balloon and exploding, right after a heartfelt goodbye with Natsumi.
  • Freudian Excuse: Despite Shurara's constant abuse of her, she stays with him because she was his favorite toy when he was a child.
  • Heel-Face Turn: Natsumi convinces her to defy Shurara, and she helps stop Gyororo.
  • Living Toys: Shurara's childhood doll, which he brought to life when he assembled his corps.
  • Tragic Villain: Loyal to her former owner who no longer treats her kindly, wishes she could stay with Natsumi but acknowledges it would be wrong, and gets blown up by Todd while saying goodbye.
  • Voluntary Shapeshifting: Is able to transform into the exact appearance of Natsumi's childhood teddy bear in order to infiltrate the Hinata house.

Mekeke

Voiced by Vorhias

The puppeteer and mind-controller of the Shurara Corps, and Shurara's Yes-Man.

  • Dropped a Bridge on Him: Saburo sets him on fire at the climax of Episode 20. Dokuku reveals in the post-credits that Mekeke did not survive.
  • Evil Laugh: Laughs maniacally and frequently once he is properly introduced.
  • Marionette Master
  • Mind Control: He can possess the minds of the people he strings up.
  • People Puppets: His method of controlling people is to string them up from above.
  • Yes-Man
    Shurara: "It gave me goosebumps!"
    Mekeke: "My goose was thoroughly bumped!"

Putata

Voiced by Thorn

The Mad Artist of the Shurara Corps who can bring his art to life. Speaks in a Totally Radical Non Sequitur cavalcade.

Dokuku

Voiced by ShazMyBot (Episode 20), Jiggly Jacob (Episode 21)

The Shurara Corps's resident ghost who hates his boss.

  • An Offer You Can't Refuse: Shurara killed Dokuku and forced him to work for him by making him a ghost and claiming that Dokuku is now bound to him. Giruru points out that Dokuku couldn't leave Shurara's side if that were the case, and Dokuku promptly leaves.
  • Anti-Villain: He's only after Keroro so that Shurara will finally free him.
  • Deadpan Snarker
  • Our Ghosts Are Different: Ours is made of steam and has a scythe for a hand.
  • Red Right Hand: His scythe arm.
  • Take a Third Option: His job is to kill Keroro, and it's either do that or return to Shurara. When he finds his brother, Giruru, he instead opts to hide out in the platoon's vaults until Shurara's gone.

Giruru

Voiced by Jiggly Jacob

A gel Keronian and Dokuku's brother who was locked in the Keroro Platoon's vaults.

Robobo

Voiced by Thorn

A robot Keronian programmed to make friends, kill said friends, and party. He has magnetic powers utilized by his magnet hands, and he can fuse people with nearby machinery. He comes in two forms: a normal Keronian-sized body and a giant mecha. He later comes back in a new giant mecha body, Shurobobo, piloted directly by Shurara. Kululu cannibalizes this body when Shurara isn't looking to create Kerobobo, a more charismatic Gundam for the platoon's use.

  • Baleful Polymorph: One of his abilities is combining people with nearby machinery.
  • Brain Uploading: He was once a living Keronian soldier who exploded after Keroro called him a nerd. Unlike other Shurara Corps members, who were resurrected in new forms to become part of the team, he was instead uploaded into a robot.
  • Captain Ersatz: His speaking mannerisms are based on Robot from The Audio Logs Of Dr Squid, who was also voiced by Thorn in a constant yell through a ring modulator.
  • Death Is a Slap on the Wrist: Defeated in both forms by Dororo in Episode 22, two of Dororo's few Bad Ass moments in the entire series, but being a robot, Shurara easily brings him back in Episode 25. He survives this time, even after getting torn apart by Kululu to become the Keroro Platoon's new giant mech.
  • Heel-Face Turn: He becomes the Keroro Platoon's new giant mech after Kululu tears him apart to make Kerobobo.
  • Humongous Mecha: His second, third and fourth forms.
  • Killer Robot
  • Large Ham: After becoming Kerobobo, he speaks with more flair, charisma and bravado.
    "May your sinuses forever be quenched!"
  • Let's Get Dangerous: After becoming Kerobobo:
    "What this party needs is an ass kicking!"
  • Life of the Party: How he views himself.
    "What this party needs is a love machine!"
  • No Indoor Voice: His principal voice is a constant yell. He is able to speak at a normal volume as Kerobobo, but he's still usually yelling.
  • Obliviously Evil: He is programmed to view the platoon as his new friends, and he is eager to show them love. Unfortunately he shows it with murder.
    "I have been programmed to show love inefficiently. By the orders of Shurara, you are my new friends. ADD ME!"

Gyororo

Voiced by LillyLivers

A young Keronian covered in eyes and has invisibility and laser powers. He acts as Shurara's eyes while spying on the platoon. He is only helping Shurara because he is endlessly entertained by Shurara's insanity.

  • Eye Beams: Has laser eye abilities, but only ever uses them once.
  • Extra Eyes
  • Faceless Eye: When he is invisible, one single radiating eye can still be seen.
  • Invisibility: Can disappear into the walls, but one single radiating eye is left visible. Dororo is the only person who can detect him in this form.
  • It Amused Me: He is a peculiar version of a voyeur: he likes to watch insane people because it entertains him. Thus, he is only helping Shurara because he gets to watch Shurara be completely nuts.
    "Seriously, if he wasn't around, I'd be watching [the Keroro Platoon] permanently. You're horrible people, but he's cracked!"
  • Killed Off for Real: One of the few aversions of the Shurara Corps. He survives his episode and is simply locked in the vaults after getting captured in a bubble.
  • Mr. Exposition: Once Dororo outs him, he explains his and Nuii's relationships with Shurara.

Yukiki

Voiced by Omahdon

A snowman Keronian with snow and ice powers. When Mekeke dies, he takes over as Shurara's right hand man. He was Keroro's commanding sergeant during a battle on Planet Fukitsculdere, but a toilet balloon landed on him. Keroro stole his sergeant's star and left him to die in the frozen tundra.

  • An Ice Person
  • Anti-Villain: Sees Keroro as a murderer and ruiner of innocent lives, and he wants to see Keroro's reign of destruction brought to an end.
  • Dropped a Bridge on Him: After a few minutes of threatening the platoon, Kululu simply blasts him with a burning hot laser, melting him into a puddle.
  • Harmless Villain: Despite trying his damnedest and at best taking out Giroro's gun, he proves to be no threat to the platoon.
  • Large Ham: Is very theatrical when he takes on the platoon himself.
    "Master of ice and snow! Freezer-off-er of your butt! I am Yukikiiiii!"
  • Revenge: He has a personal vendetta against Keroro for taking his job and leaving him to die.
  • Snowlems
  • Tragic Villain: Had both his career and life taken from him in one night.

Kagege

Voiced by BigTUnit1

A mysterious, faceless Keronian with the ability to bring shadows to life. Keroro called him a wiener in front of his mom, and now he seeks revenge.

  • Anti-Climax: Invoked with his crying. Travis gave him a deep wheeze followed by a pitiful grunt as a joke about people who dramatically build up a sneeze, but the sneeze itself is small.
  • Casting a Shadow: His ability is to bring people's shadows to life, which have roughly the same abilities as the original person.
  • Killed Off for Real: A special aversion in the Shurara Corps, alongside Shurara himself. All of the other subordinates either died during the course of the season (E.G.: Putata, Mekeke, Nuii) or were dead before and resurrected by Shurara in their backstories (E.G.: Dokuku, Giruru, Robobo). Kagege was always alive priornote  and he survives the whole season.
  • Inelegant Blubbering: His sobbing is a loud wheeze followed by a pitiful grunt.
  • No Mouth
  • Pragmatic Villain: He knows that fighting the platoon himself would be hopeless due to their track record of killing his colleagues, so he uses the Keroro Platoon's shadows against them as an equal fight instead.
  • Revenge: Keroro called him a wiener in front of his mom. This had as big an impact on him as Yukiki being left to die.
  • Something We Forgot: The platoon defeat him and tie him up halfway through the episode. At the very end, he's still lying there sobbing.
