    Keroro Platoon 

Sergeant Keroro

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. Voiced by Mugiwara Yoshi.

Private Tamama

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. Voiced by ThornBrain.

Corporal Giroro

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. Voiced by ThornBrain.

Lance Corporal Dororo

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. Voiced by ThornBrain.

  • 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: Late-Season 2 onward.
  • 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

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. Voiced by InfamousGentleman.

  • 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

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. Voiced by codeblackhayate.


Fuyuki Hinata

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. Voiced by ThornBrain.

Natsumi Hinata

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. Voiced by LillyLivers.

Aki Hinata

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

Koyuki Azumaya

A cheerful ninja girl with a crush on Natsumi. One of Dororo's few real friends (and Natsumi's for that matter). Voiced by Revy Moonshine (Episode 4-18), Thaichestnuts (Episode 22-present).

  • 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

Fuyuki's secret admirer with an extreme split personality. Voiced by Dobuchu.

Paul Moriyama

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. Voiced by BigTUnit1.

  • 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 


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 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. Voiced by BigTUnit1.

  • 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"...

Chief Medic Pururu

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. Voiced by LillyLivers.

  • 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

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. Voiced by ThornBrain.


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. Voiced by BigTUnit1.

  • 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.


The young Ocelot from Metal Gear Solid 3: Snake Eater who started appearing in Season 3. He doesn't have a clearly defined character yet. Voiced by Xcaliborg (Episode 19), BigTUnit1 (Episode 22)
  • Shout-Out: His line in Episode 22 is a quote from one of Jiggly Jacob's Sims 4 videos.


Future Kululu

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. Also voiced by InfamousGentleman.


An unnamed Admiral (now a Captain) 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. Voiced by Jiggly Jacob.

  • 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.
  • 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.

Lieutenant Garuru

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. Voiced by BigTUnit1.

  • 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

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. Voiced by ThornBrain

  • 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

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

  • 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.
  • Crossdressing Voices: Many were surprised when they found out he was voiced by Lilly, who until then had only voiced girly females such as Natsumi.
  • 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

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. Voiced by BigTUnit1.


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 he can be quite mean to his own Corps. Voiced by ThornBrain.

  • Bad Boss: He abuses and intimidates his subordinates, particularly the meek Nuii, and he reveals he kidnapped most of them.
  • Big Bad: For Season 3.
  • Expy: His personality takes many cues from Invader Zim and Handsome Jack.
  • Hidden Depths: Genuinely misses Mekeke after he's killed in action.
  • Jerkass
  • Large Ham
  • 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.
  • Revenge: All we know about his motivations to kill Keroro is that Keroro did something to him in the past. This is par for the course for SFA villains.
  • Schoolyard Bully All Grown Up


A meek doll Keronian and the subject of most of Shurara's abuse. Voiced by King Theo (Reset-Episode 20), Thaichestnuts (Episode 22-on).


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

  • Evil Laugh: Laughs maniacally and frequently once he is properly introduced.
  • Killed Off for Real: Saburo sets him on fire at the climax of Episode 20. Dokuku reveals in the post-credits that Mekeke did not survive.
  • 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!"


The mad artist of the Shurara Corps who can bring his art to life. Voiced by Thorn.


The Shurara Corps's resident ghost who hates his boss. Voiced by ShazMyBot for Episode 20, Jiggly Jacob for Episode 21.

  • 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.


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


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. Serves as the villain for Episode 22.
