* PetTheDog: He remains a jackass for most of the series but he appears to have a genuine heart to heart with Keroro in ''Reset'', even admitting to enjoying their conversation a little bit and give the Platoon a second chance at invading earth. This... ''doesn't'' go over well when he gets demoted and returns four months later to find that they're ''still'' dicking around and making no progress.

The main character of the ''Franchise/MetalGear'' games makes recurring cameos to reference said series. He mostly appeared as a recurring OneLiner gag, but became an actual InUniverse entity in Episode 7.

* ReferenceOverdosed: To ''Franchise/MetalGear'', specifically the first few ''VideoGame/MetalGearSolid'' games.

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

* {{Expy}}: His voice and mannerisms are taken directly from Thorn's versions of Franchise/SonicTheHedgehog and Davis from ''WebVideo/TamersAbridged''.

* NoMouth

The main character of the ''Franchise/MetalGear'' games makes recurring cameos to reference said series. He mostly appeared as a recurring OneLiner gag, but became an actual {{in-universe}} entity in Episode 7.

* DeathIsASlapOnTheWrist: Defeated in both forms by Dororo in Episode 22, two of Dororo's few BadAss 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.

* ButtMonkey: His role as forgotten ButtMonkey in [[Manga/KeroroGunsou the original]] is replaced with that of a directly/emotionally-abused punching bag.

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

* BritishAccents: Has a slight British tint to mirror his posh upbringing [[OohMeAccentsSlipping and to differentiate him from Thorn's other voices]].

* UsefulNotes/AmericanAccents: Sports a Brooklyn accent.

* TheAce
* AffablyEvil: UpToEleven. He's so nice, it drives Giroro insane. [[spoiler: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.]]

* ArcVillain
* TheComicallySerious: The one time he says anything remotely silly (E.G. "Well that was wacky"), he's completely deadpan.

* AxCrazy

* KnightOfCerebus: [[spoiler:He kills Koyuki after his [[PreMortemOneLiner very first line]]. Practically every paranoia-drenched scene after subverts this.]]
* TheLancer: To Garuru.

* CheerfulChild: Despite looking physically matured, he is played as a child.

* HarmlessVillain: 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.

* EvilLaugh: A big, maniacal one.

* TheHyena

* MarionetteMaster

* YesMan

* ArtInitiatesLife

* BoomHeadshot

* {{Expy}}: His voice and mannerisms are taken directly from Thorn's versions of Davis from ''Tamers Abridged'' and Franchise/SonicTheHedgehog.

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.

* KillerRobot

-->"What this party needs is a '''love machine'''!"

* ExtraEyes

* AnIcePerson

* HarmlessVillain: Despite trying his damnedest and at best taking out Giroro's gun, he proves to be no threat to the platoon.

* {{Snowlems}}
* TragicVillain: Had both his career and life taken from him in one night.

* SomethingWeForgot: [[spoiler:The platoon defeat him and tie him up halfway through the episode. At the very end, he's still lying there sobbing.]]

!!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.

* ADegreeInUseless: WordOfGod 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 [[EntertaininglyWrong completely wrong]] diagnoses of the platoon confirm that in-universe.
* UsefulNotes/AmericanAccents: Sports a Brooklyn accent.
* CloudCuckoolander: Most obvious as a kid. She seems fairly focused as an adult, but still has moments where her warped mind is noticeable.
* CuteAndPsycho: Attractive and pleasant; secretly harvesting organs for cash.
* DistaffCounterpart: 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).
* TheDitz: As a child, she doesn't seem aware of her surroundings or make clear conversation.
* HilariouslyAbusiveChildhood
-->"When [[TheAlcoholic my mommy drinks juice]], nobody's happy."
* TheMole: She's really there to learn the platoon's weaknesses and relay them to Garuru.
* StickyFingers: 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''.

* DuelToTheDeath: With Raiden in the Season 2 finale. According to the credits, both lost. They're both back to life in ''Reset''.
* ReferenceOverdosed: To ''Franchise/MetalGear'', specifically the first few ''VideoGame/MetalGearSolid'' games.

!!Raiden
!!!Voiced by [=BigTUnit1=]
The fellow main character of the ''Franchise/MetalGear'' games has also started appearing in Season 2. He does not reference [=MGS=] so much as act like a walking metrosexual Facebook/Twitter feed.

* TheDitz
* DuelToTheDeath: With Snake in the series finale. According to the credits, both lost. They're both back to life in ''Reset''.
* SmallNameBigEgo: He thinks he rocks. Almost no characters are aware of his presence.

!!Ocelot

!!!''[[VideoGame/MetalGearSolidVThePhantomPain MGSV]]'' Revolver Ocelot - Voiced by Jiggly Jacob (Episode 24)
Ocelot starts appearing in Season 3, at first as his ''VideoGame/MetalGearSolid3SnakeEater'' version, and then getting progressively older. Starting with Episode 22 he quotes various strange things Jiggly Jacob has said.

* ShoutOut: His lines in Episodes 22 and 24 are quotes from one of Jiggly Jacob's ''Sims 4'' videos.

!!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 [[Series/MysteryScienceTheater3000 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''.

* TheAntagonist: For the first season.
* BeardOfEvil: Has a pencil mustache, [[ShoutOut as inspired by Ron Mael of]] Music/{{Sparks}}.
* EvilLaughter: He alternates between the "HEGH" laugh and an actual evil cackle.
* KnightTemplar: [[spoiler:He's trying to kill Keroro]] so that the mission to invade Earth actually gets accomplished.

!!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.

* TheAntagonist: For all of Seasons 1 and 2, and returns to this spot for Episode 23.
* BadBoss
* BigBad: For all of Seasons 1 and 2.
* DrivenToSuicide: In Episode 16, Kilili hits HQ with all of his stored negative energy, severely depressing him. [[SuicideAsComedy Everyone in the universe commits suicide shortly after]]. The suicide is undone in ''Reset''.
* DullSurprise: 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.
* MustHaveCaffeine: 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.
* TheVoice: Until Episode 22, he's never seen; only heard over intercoms, answering machines, or while having a monologue to a black screen.

* KilledOffForReal: [[spoiler: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 (E.G.: Dokuku, Giruru, Robobo). Shurara survives the whole season.]]

* SpikesOfVillainy

* WellDoneSonGuy: He is angry that [[spoiler:Viper was happy to reconnect with Keroro in adulthood but continued to not know or care about Shurara]].

* KilledOffForReal: [[spoiler: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 (E.G.: Dokuku, Giruru, Robobo). Kagege was always alive prior[[note]]He was presumed dead in the past but he was simply in hiding[[/note]] and he survives the whole season.]]

* Snowlems

* SchoolyardBullyAllGrownUp

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

* DroppedABridgeOnHim: [[spoiler:Episode 24 ends with her flying directly into Todd Sirkowski's hot air balloon and exploding, directly after a [[BlackComedy heartfelt goodbye with Natsumi]]]].

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.

* {{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.

* BlobMonster

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.

* HumongousMecha: His second form.
* KilledOffForReal: [[spoiler:Defeated in both forms by Dororo, two of Dororo's few BadAss moments in the entire series]].

* FacelessEye: When he is invisible, one single radiating can still be seen.

* ItAmusedMe: He as 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.

A snowman Keronian with snow and ice powers. When [[spoiler:Mekeke dies]], he takes over as Shurara's right hand man.

A mysterious, faceless Keronian with the ability to bring shadows to life.

'''Warning''': Unmarked spoilers ahead for Season 1 and 2.

In the Abridged series, Keroro is a useless, self-absorbed JerkAss 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 [[GratuitousSpanish Hispanic]]. The entire series revolves around his friends and peers wanting to kill him because they hate him so much. Voiced by Mugiwara Yoshi.

* JerkAss: [[UpToEleven Funimation couldn't make Keroro]] [[ExaggeratedTrope this awful a person]].

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=].

* StaticCharacter: Despite showing moments of HiddenDepths throughout the series, Tamama never changes much beyond her CloudCuckoolander characterization. Writer Travis admits that he would like to develop Tamama's character more beyond this. Her appearances in ''Podcast/AskGiroDoroSFA'' made the effort to emphasize her sarcastic side and her tenuous relationship with Keroro.

* NotAllowedToGrowUp: WordOfGod says Tamama is the [[OlderThanTheyLook Keronian age-equivalent of a 20-year old]], except she has Keronian dwarfism.

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=].

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 CharacterDevelopment has led him to not take Keroro's crap so much anymore and settle into a happy relationship with Giroro. Voiced by [=ThornBrain=].

* StraightMan: Late-Season 2 onward.

The biggest personality reversal from the original ''Keroro Gunsou''. Kululu isn't the transparently scheming, constantly-giggling TokenEvilTeammate like his counterpart, but is rather an understated, keeps-to-himself, sarcastic, apathetic JerkAss. Voiced by [=InfamousGentleman=].

Mois is a sweet alien girl with a big crush on her longtime family friend Keroro. As opposed to the [[Manga/SgtFrog 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.

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=].

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=].

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

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).

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

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=].

Viper is a half-snake, half-humanoid space pirate whose TangledFamilyTree 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 [[spoiler: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=].

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=].

* DullSurprise: His usual speaking voice. You get the sense that he's not crazy about his job.

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 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=]

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

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=].

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 YesMan. Voiced by Vorhias.

* KilledOffForReal: [[spoiler:Saburo sets him on fire at the climax of Episode 20. Dokuku reveals in the post-credits that Mekeke did not survive.]]

The mad artist of the Shurara Corps who can bring his art to life. 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. Serves as the villain for Episode 22.

* MikeNelsonDestroyerOfWorlds: Despite being an invader by [[spoiler:(failed)]] profession, his only real successful destruction of life was an accident.

* AmbiguouslyGay: Averted. One of his nicknames is "fagmuffin". Becomes subverted when he ends up being straight only because he is a "she".

* [[spoiler:HappilyMarried: He and Dororo as of Episode 15]].

* {{Only Sane Man}}/{{Straight Man}}: To the rest of his platoon. Usually.

By Season 2, heaps of CharacterDevelopment has led him to not take Keroro's crap so much anymore [[spoiler:and settle into a happy relationship with Giroro]]. Voiced by [=ThornBrain=].

* TheChewToy: [[CrossesTheLineTwice Especially as a kid.]]

* [[spoiler:HappilyMarried: He and Giroro as of Episode 15]].

* [[IllGirl 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. The kicker? [[CrossesTheLineTwice He got them all because he wanted to make friends.]]
** Of course, come the next few episodes, it's pretty clear they're not fully dormant or non-contagious.
** Dororo releases his diseases into the wilderness like wild animals in the series finale. It is unknown if he does the same following ''Reset''.

* ObliviousToLove: 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; [[spoiler:[[TheyDo then they kept going]]]]).

* StartOfDarkness: The team was in fear of this due to [[spoiler:Future Kululu wanting to kill them all, which is taken seriously in Episode 12. He actually seems pretty mellow about the team]].
* TokenEvilTeammate: Subverted. Throughout the first season he's about as blatant as his [[Manga/SgtFrog main series counterpart]]. However [[spoiler: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 collapsed all of Uganda with porn.

* [[OnlySaneMan Only Sane Woman]]/[[StraightMan Straight Woman]]

* [[DoggedNiceGuy Dogged Nice Girl]]: Her to Natsumi in Seasons 1 and 2. Natsumi only wants her as a friend.

** An additional subversion occurs in the Season 2 finale: he is revealed to also be [[spoiler:Keroro's]] father, and both he and Dororo know this. However [[spoiler:Keroro]], [[IdiotHero 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 [[spoiler:[[Podcast/AskGiroDoroSFA until Keroro appears in the Q&A blog]].]]

* TheDitz: As a child.

The fellow main character of the Franchise/MetalGear 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=].

* DefeatMeansFriendship: Implied, and WordOfGod states this was the intention.

* DefeatEqualsFriendship: [[spoiler: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.]]

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=].

* BadBoss: He abuses and intimidates his subordinates, particularly the meek Nuii.

* {{Its Personal}}/{{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.

* [[spoiler:KilledOffForReal: Saburo sets him on fire at the climax of Episode 20. Dokuku reveals in the post-credits that Mekeke did not survive.]]

** [[spoiler:BoomHeadshot]]
** [[spoiler:WhyDontYouJustShootHim]]

* TakeAThirdOption: 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 their vaults until Shurara's gone.

* SuspiciouslySimilarSubstitute: Parodied with Paul's Puppet Momoka, which he uses [[spoiler:after her death to keep people from knowing she's dead so that he can keep his job]].
* RevolvingDoorCasting: She was voiced in Episode [=2R=] by [=LillyLivers=] as a backup, following many failed attempts to find and hold down a voice actor for her before she ever debuted. She finally found a stable VA in Narusasu [[spoiler:before the character was killed off]]. This trope is the reason she was removed from most of Season 1 out of spite.

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 Travis.

* SuspiciouslySimilarSubstitute: Parodied with Paul's Puppet Momoka, which he uses [[spoiler:after her death to keep people from knowing she's dead so that he can keep his job]].

* NewPowersAsThePlotDemands: His magic pen was never addressed in the series, and he doesn't speak so he can't explain anything. Thus comes Episode 17 when he rescues the Hinatas with a drawing of a shield, and Episode 20 when he suddenly gains explosive powers and [[MakesJustAsMuchSenseInContext incendiary spraypaint]].
* [[spoiler:SuddenlyVoiced: Albeit briefly, by fellow voice-based running gag [=MrFailGame=] in the series finale.]]

* AuthorAvatar: The ''Podcast/AskGiroDoroSFA'' audio blog revealed that it and SFA reach the real world via transmission from Thorn.

!!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[[spoiler:, which is just a cover for her to find out the platoon's weaknesses.]] Voiced by [=LillyLivers=].

* CuteAndPsycho: Attractive and pleasant; [[spoiler:secretly harvesting organs for cash]].

* [[spoiler:TheMole: She's really there to learn the platoon's weaknesses and relay them to Garuru.]]

* [[spoiler:DuelToTheDeath: With Raiden in the Season 2 finale. According to the credits, both lost. They're both back to life in ''Reset''.]]

* [[spoiler:DuelToTheDeath: With Snake in the series finale. According to the credits, both lost. They're both back to life in ''Reset''.]]

!!Viper

Viper is a half-snake, half-humanoid space pirate with an apparent history with the Keroro Platoon, (he's Dororo's dad). After capturing Dororo and Koyuki in Episode 4, he is relegated to an occasional cameo, usually voice-only. Voiced by [=BigTUnit1=].

* LukeIAmYourFather: Averted. The characters just seem to know this already.
** Then subverted, 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: [[spoiler:he is revealed to also be Keroro's father, and both he and Dororo know this. However Keroro, [[IdiotHero 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 [[Podcast/AskGiroDoroSFA until Keroro appears in the Q&A blog]].]]
* TangledFamilyTree: It seems straightforward at first: Viper, his father, his wife, their kids. But then in Episode 19 we meet his "Mom-Son" and "[[ItMakesSenseInContext Dad-Train]]"...


!!Future Kululu

Kululu's future self. [[spoiler:He is apparently the Kululu seen from Episode 6 through Episode 10, and the present-day Kululu [[Series/MysteryScienceTheater3000 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 Jpace92.
----

An unnamed Admiral 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.

* [[spoiler:TheAntagonist: For all of Seasons 1 and 2.]]
** [[spoiler:BigBad]]

* [[spoiler:DrivenToSuicide: In Episode 16. The suicide is undone in ''Reset''.]]

* TheVoice: Never seen; only heard over intercoms, answering machines, or while having a monologue to a black screen.

* [[spoiler:DroppedABridgeOnHim: His ship unceremoniously explodes. This is undone in ''Reset''.]]

* [[spoiler:DroppedABridgeOnHim: His ship unceremoniously explodes. This is undone in ''Reset''.]]

* [[spoiler:DroppedABridgeOnHim: His ship unceremoniously explodes. This is undone in ''Reset''.]]

* [[spoiler:DroppedABridgeOnHim: His ship unceremoniously explodes. This is undone in ''Reset''.]]

* {{The Antagonist}}/{{Big Bad}}: For Season 3.
* BadBoss: His introduction involves him intimidating his subordinate, Nuii.
** SchoolyardBullyAllGrownUp
* {{Expy}}: His personality takes many cues from ''WesternAnimation/InvaderZim''.
* {{Its Personal}}/{{Revenge}}: All we know about his motivations to kill Keroro.

* LiteralMinded: Stock phrases such as "give them no quarter" or "I ''ass''ume you are the one behind this" take on different meanings in Shurara's mind.

* {{Mind Control}}/{{People Puppets}}: He can possess the minds of the people he strings up.

* BlackComedy: Buried in the piles of {{non sequitur}}s that he says are mentions of being molested as a child by his uncle and hating his father. [[spoiler:[[BoomHeadshot His death is darkly comical as well]].]]

* AmericanAccents: Sports a Brooklyn accent.

Kululu's future self. [[spoiler:He is apparently the Kululu seen from Episode 6 through Episode 10, and the present-day Kululu is trapped somewhere in the meantime. Kululu turns into him at the end of Season 2, then back to normal in ''Reset'']]. Also voiced by Jpace92.
