!Maskmen
[[folder:Takeru/Red Mask]]
!!Takeru/[[red:Red Mask]] | [-Actor: Ryosuke Kaizu-]
[[quoteright:242:https://static.tvtropes.org/pmwiki/pub/images/redmask_8141.jpg]]
The leader of the Maskmen, the first to be spotted by Commander Sugata. Expert in Karate and is a UsefulNotes/FormulaOne race driver. He met and fell in love with a girl named Mio, and even when she is revealed as Princess Iyal, he still clings to be reunited, giving him strength to push on. Used to be an extremely bratty kid, but after meeting his grown-up self, he matured up. Though he's basically TheHero, he's much more temperamental.
----
* TheAce: He is actually one, but in the past, he's anything but. [[OldShame He would still hide that non-Ace past because it is embarrassing]].
* BadassDriver: He's a UsefulNotes/FormulaOne racer, thus instantly qualifies him as one.
* BareFistedMonk: Like the rest of his team, he's specialized in hand-to-hand combat.
* BrattyHalfPint: When he was a kid.
* CoolSword: Masky Blade
* {{Determinator}}: This is his main quality, which is why Sugata got him as a Maskman.
* {{Expy}}: Closer to the ShoutOut to the ''Robot Romance Trilogy'', Takeru draws similarities with [[{{Anime/Daimos}} Kazuya Ryuuzaki]] the most, since he is the male StarCrossedLovers, runs on ThePowerOfLove, and is a karateka.
* FinishingMove: ''[[DiagonalCut Masky Crash]]''
** Episode 6 has him utilizing the all powerful ''[[LimitBreak God Hand]]'' technique.
* GetAHoldOfYourselfMan: Is the one who'd do this to his friends who needs it.
* TheHero: While the other team members get focus, Takeru is TheLeader of the team and the one driving the plot.
%%* HotBlooded
* IKnowKarate: As a karate practitioner, he naturally incorporates some of it into his fighting style.
* LawOfChromaticSuperiority: Gets his own buggy (Spin Cruiser) and has two powerful {{Finishing Move}}s he can use on his own, plus he is Jet Cannon's designated pilot.
* TheLeader: Designated as such by Sugata.
* MyFutureSelfAndMe: It's only after meeting his future Maskman self that little Takeru stopped being a brat.
* OldShame: An in-universe example. His BrattyHalfPint past is something he didn't want to reveal to his friends, so he hid the facts about his bratty self.
* SignatureMove: ''[[ImpaledWithExtremePrejudice Laser Arrow]]''
* StarCrossedLovers: With Mio/Iyal. [[spoiler:He spends most of the show chasing after her, and once Zeba is defeated they end having to part ways again. Despite this, Takeru encourages Ial to go back to her kingdom to rule and rebuild it rather than stay with him, content with the time they spent together, however brief it was.]]

* CasanovaWannabe: He tries, but he just can't get a girl.
* CowardlyLion: Was turned into one at a point, but he gets better.
* EpicFlail: One part of Masky Rod.

* SuperStrength: Shown in ep 13 where in his civilian identity throws around the other Maskmen like ragdolls [[spoiler: of course the Maskmen were faking the fight to draw out a spy, but it was still impressive]]
* TheSmartGuy: A skilled mechanic.

[[folder:Akira/Blue Mask]]
!!Akira/[[blue:Blue Mask]] | [-Actor: Issei Hirota-]
[[quoteright:241:https://static.tvtropes.org/pmwiki/pub/images/bluemask_3806.jpg]]
The youngest of the team, Chinese Boxing and swordplaying expert and the one to crack jokes, most of the time. He left his mother to train (actually was drafted to the Maskman force) and strives to make his mother proud by training hard.
----
* BrainwashedAndCrazy: [[spoiler: At one point, he is possessed by a monster, turning him into the fencer Unas and proceeds to OWN the Maskmen, HARD. He gets better, of course.]]
* ChildProdigy: Was recognized by Sugata as one in the ways of martial arts, which is why he was chosen for Maskman.
* HeroesPreferSwords: He is an expert at [[MasterSwordsman swordplay]]...but his individual weapon is tonfa.
* JustAKid: He really does not like being treated as a kid at first, even if he is only sixteen.
* {{Keet}}: He is the youngest of the team and also the most bubbly.
* KidAppealCharacter: He is the youngest of the team and most expressive with his emotions.

[[folder:Haruka/Yellow Mask]]
!!Haruka/[[gold:Yellow Mask]] | [-Actress: Yuki Nagata-]
[[quoteright:243:https://static.tvtropes.org/pmwiki/pub/images/yellowmask_3254.jpg]]
A {{Ninja}} (and damn proud of it). Ever since she's a child, she's raised without enjoying girly things (like dolls). As such, she has a hidden sensitive spot for girly things. She's best buds with Momoko.
----
* BattleTops: Masky Rotor.
* TheBigGirl: The more obvious ActionGirl, that is.
* BoyishShortHair: Has short hair, befitting her tomboyish personality.
* CutenessProximity: Raised as a ninja, Haruka was forbidden to enjoy anything cute or girly, thus explaining her soft spot on cute things despite her tomboyish exterior.
* DoppelgangerAttack: ''Yellow Mask Kage Bunshin''[[note]]Shadow Clone[[/note]]
* {{Expy}}: She's basically a GenderFlip version of [[Series/KagakuSentaiDynaman Ryu Hoshikawa]] since both of them came from the line of ninjas.
** Besides her ninja background, Haruka is the Sentai equivalent of [[Anime/VoltesV Megumi Oka]] for having the same color scheme.
* KillerYoYo: Again, Masky Rotor.
* {{Ninja}}: Is often counted as one in later team-ups, such as Chou Super Hero Taisen and Strongest Battle.
%%* PowerHair
* [[ProudWarriorRaceGuy Proud Ninja Girl]]: Is prideful of her ninja lineage.
%%* {{Shorttank}}
* TomboyAndGirlyGirl: Tomboy to Momoko's Girly Girl.

A gentle hearted girl who is really kind to children and teaches martial arts in her free time. She's an expert in Tai Chi Quan and tends to get very emotional in things she does. Best buds with Haruka.
----
* FlowersOfFemininity: Her status as GirlyGirl couple with her dear "Carol Love" flowers.
* FriendToAllChildren
* TheHeart: Less 'chick' than most others, since this is Maskman, Sentai of CharlesAtlasSuperpower, [[ActionGirl she can be as strong as you can get]].
* HeroicRROD: In the episode where she fought against a monster untransformed for so long, it drained her fatigue that after firing the Shot Bomber, she collapsed, reverts back to human form and rendered unconscious.
** {{Determinator}}: All because she made a promise about teaching her students about making the impossible possible as long as one pushes their efforts to their limits, she ''absolutely'' refuses to transform and to her credit, she actually punches a hole through the MonsterOfTheWeek's chest untransformed and even after she transformed, she still wrecks the monster hard enough so it can be shot with Shot Bomber. However...
** UnwittingPawn: That is exactly what Anagmas was counting on her, resulting the fall of Great Five. To her comfort, she still saved her students and their spirits.
* LadyOfWar: It's Tai Chi Quan, the martial arts for LadyOfWar.
* MythologyGag: Is the Pink Ranger, uses Ribbon as her weapon, and part of her name is 'Momo'. [[Series/DaiSentaiGoggleFive We've had this concept before.]]
* TomboyAndGirlyGirl: Girly Girl to Haruka's Tomboy.

----

* RebelliousPrincess: Turned against Tube after falling in love with Takeru.
* RoyalBlood: Princess of the Tube Empire.

[[/folder]]

!Underground Empire Tube
[[folder:In General]]
A vast civilization from the underground. Though once pacifist, after the rise of Emperor Zeba, Tube began building up its forces for an invasion of the surface world.
----
* ArmiesAreEvil: Zeba's rise as ruler of Tube saw the Tube embracing militarism in preparation for invading the surface world.
* ContrastingSequelAntagonist: The Reconstructive Experiment Empire Mess in ''Series/ChoushinseiFlashman'' were AlienInvaders, while the Tube are an imperialist army from the underground seeking to conquer the surface. Mess was founded purely to fulfill their ruler's megalomaniacal intentions, while Tube was originally a peaceful kingdom that was [[TyrantTakesTheHelm hijacked]] by a despot seeking to conquer the surface world. The Mess created all of their generals through genetic engineering, while Tube recruits most of their generals from the various tribes that make up their empire.
* TheEmpire: A militaristic power seeking to dominate more land. Notably, they have a lot of the trappings of a traditional empire, being a union of various tribes under a single authority.
* EvilIsDeathlyCold: Tube is stated to be a very cold place, on account of being deep underground.
* EvilIsNotWellLit: Justified, as they live underground and thus don't have as much need for light as surface dwellers.
* MonsterOfTheWeek: The Doggler Beasts, which are thawed out from a frozen cave to fight the Maskmen. A few of the early ones were actually two monsters in one, which were composed of an "Underground Doggler" and a "parasite" that would grant it power.
* {{Mooks}}: The Ungler Soldiers, essentially your standard Sentai FacelessGoons.
* StandardEvilOrganizationSquad: Zeba's inner circle, who command the forces of Tube in battle.

[[folder:Emperor Zeba]]
!!Emperor Zeba[[spoiler:/Lethal Doggler II]] | [-Actor: Creator/SeizoKato (voice), Hideaki Kusaka (suit)-]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/zeba_ep1.jpg]]
The mysterious ruler of Tube. He seized control of the empire from its original rulers, the Igam family, in a coup and is now set on conquering the Earth so he can rule both the underground ''and'' the surface.
----
* AlienBlood: A variant. He ''sweats'' green ooze.
* AmbiguouslyHuman: From the beginning it's not clear whether Zeba is an underground human like Igam or Baraba, or something more alien. [[spoiler:He eventually turns out to be an Earth Beast, albeit one that worked its way up the food chain.]]
* BadBoss: Even by the standards of Sentai villains, Zeba is an abysmal boss. Just about every episode has him zapping his subordinates with lightning because they did something to displease him.
* BigBad: Zeba is responsible for the transformation on the once peaceful Tube empire into a dark militaristic kingdom in order to invade the surface world.
* CannibalismSuperpower: [[spoiler: Cannibalized his own parent to absorb its power for himself.]]
* CoolMask: Wears an ornate blue mask that covers his face, leaving only his eyes visible.
* TheEmperor: His title as ruler of the underground. Unlike most other Emperors in the franchise however, he actually has a claim to the title given how similar Tube is to a traditional empire.
* EvenEvilHasStandards: Even he was against reviving Lethal Doggler, the beast which once terrorized the underground. [[spoiler:Subverted later. Zeba wasn't worried about Lethal Doggler returning, he was worried about being ''caught''.]]
* EvilOverlord: Plays just about every Evil Overlord trope unabashedly straight, up to and including stealing his domain from the rightful rulers.
* FakeKing: Stole the position from the real king.
* GloriousLeader: As the head of Tube's military dictatorship, his subordinates have constructed a CultOfPersonality around him revering him as a great and wise leader.
* LightIsNotGood: His appearance is shiny and sparkly, but at heart he's a cruel and cold dictator.
* MakeMyMonsterGrow: [[spoiler:In the finale he absorbs the energy of the Maskmen's FinishingMove to enlarge himself.]]
* MolotovTruck: [[spoiler:In the finale he does this with his own headquarters, jampacking with Evil Particles and sending it to the surface so he can blow it up and scatter the particles all across Earth's atmosphere, corrupting it to be like Tube's underground environment.]]
* MookPromotion: [[spoiler:He's basically a MonsterOfTheWeek that worked his way up to BigBad.]]
* OneWingedAngel: In the final battle, [[spoiler:Zeba assumes his true form as Lethal Doggler II after being exposed by Ial and Igam.]]
* OrcusOnHisThrone: Despite his immense power, and the fact that he can take on all five Maskmen with ease, Zeba never takes to the field for most of the series and instead uses his powers to punish his subordinates for failing to defeat the Maskmen.
* TheStoic: Even when he's furious, Zeba rarely raises his voice.
** NotSoStoic: The prospect of Lethal Doggler being revived makes him visibly unnerved.
* SuperiorSuccessor: [[spoiler:The first Lethal Doggler tried to take over the underground and was slain. Zeba, the second Lethal Doggler, succeeded in taking over the underground and defeating the Igam family.]]
* TakeOverTheWorld: Aims to bring both the surface and underground under his control.
* TechnicolorDeath: [[spoiler:Bleeds red energy like other Ground Beasts then melts into energy which forms into a face which float up in the sky and explodes four times.]]
* ToCreateAPlaygroundForEvil: Seeks to terraform Earth's surface to be cold and dark like Tube.
* TyrantTakesTheHelm: After overthrowing the Tube royal family in a coup, Zeba turned Tube from a pacifist kingdom into a militaristic empire.
* VillainousBreakdown: Whenever a clue to the Lethal Doggler emerges, he desperately aims for that hint to be destroyed at all costs. This comes into the forefront in the endgame when [[spoiler:a ball delivered by the Igam Dragon reveals that he is Lethal Doggler's son.]]
* VillainousLegacy: [[spoiler:He turns out to be the spawn of an earlier Imperial Beast, Lethal Doggler, destroyed by the ''original'' Tube royal family. Driven both by hatred against humans on both sides of the crust as well as his ancestor's lust for domination, he wiped out all of the Tube royal family save Ial and Igam, whom he used as his pawns.]]
* YouHaveOutlivedYourUsefulness: [[spoiler:In the finale he sacrifices Igam, Fu-Min, Oyo-bu and even his own SupervillainLair in a final bid to conquer the surface.]]

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/earth_imperial_commander_baraba.jpg]]
A powerful warrior of the Baluga Tribe who serves as supreme commander of the Tube Empire's armies.
----
* TheBrute: He's both a powerful warrior and skilled swordsmen, in addition to being Tube's military commander.
* CoDragons: Starts off on equal footing with Igam, though his failures eventually lead to him falling out of favor with Zeba.
* CoolSword: His MidSeasonUpgrade gives him one.
* EvenBadMenLoveTheirMamas: He's a very bad man, but Baraba genuinely loves his mama. [[spoiler:When his mother gets killed by a MonsterOfTheWeek, it allowed him to gain enough courage to slay the monster and gain his own MidSeasonUpgrade.]]
* LastVillainStand: [[spoiler:After Zeba marks him for death for his continued failures, he's allowed a final chance to defeat Red Mask. He ends up getting slain by Takeru in a duel, after having been tricked by Kiros into giving him Ial.]]
* UnwittingPawn: Gets tricked by Kiros into taking Ial out to use as a hostage against Takeru, allowing Kiros to swoop in and claim her.

The crown prince of the original Tube royal family, he serves under Zeba in the hopes of succeeding him and restoring his family's rule. [[spoiler:Is actually female, having had to disguise herself as a man in order to inherit the throne of Tube.]]
----
%%* ActionGirl
* TheAtoner: [[spoiler:In the finale, she's repented of all the bad things she's done by becoming a [[HeelFaithTurn Buddhist nun]].]]
* BastardUnderstudy: Igam's goal is to grow close to Zeba in order to succeed him and take back the throne for the Tube royal family.
%%* {{Bifauxnen}}
* BlingOfWar: His suit has gold highlights.
* CainAndAbel: Seeks to murder Ial to restore his family's honor after she fell in love with a surface dweller.
* CombatStilettos: They're there, but more for making Igam taller than to be sexy.
* CrosscastRole: Is played by the female Mina Asami despite being male. [[spoiler:Subverted when it turns out she was really a woman in disguise, making it more just a case of heavy-handed {{Foreshadowing}}.]]
* DarkActionGirl: [[spoiler:The reveal she's a woman does nothing to make her any less of an effective fighter.]]
* DragonKnight: Igam's armor has a draconic motif.
* TheDragon: Igam is Zeba's second-in-command and the lead enforcer of Tube.
* DragonWithAnAgenda: Namely, retaking the throne and getting revenge on Takeru for wooing Ial and apparently disgracing their family name.
* EvenEvilHasLovedOnes: Genuinely cares for and appreciates his loyal bodyguard Fumin.
* EvenTheGirlsWantHer: The movie has Igam wooing a mermaid into helping Tube with their plans. [[spoiler:Given the reveal about ''her'' true gender...]]
* TheEvilPrince: As a counterpart to Iyal's desire for peace.
* EvilWearsBlack: Wears a mostly black outfit, though he's comparatively less evil than the likes of Zeba or Baraba.
* {{Expy}}: Considering the ShoutOut to ''Anime/RobotRomanceTrilogy'', Igam is basically the [[Anime/{{Daimos}} Richter]] for Ial's Erika, although there are elements of [[Anime/VoltesV Prince Heinel]] (being outcasts of the fallen royal family who wants to rise through the ranks of their kingdoms to prove themselves and restore family honor) and [[spoiler:[[Anime/GodSigma Teral]] (High-ranking female general who convincingly disguised herself as a man)]]
* HeelFaceTurn: [[spoiler:After much convincing from the Maskman and Ial and the reveal of Zeba's true intentions, she helps the Maskman unmask Zeba's ruse.]]
* KnightTemplar: Does everything he does in the name of restoring his family to power, though he was down with Zeba's invasion of the surface world and was even willing to murder his own sister.
%%* LadyOfWar
* MeaningfulName: His name is Filipino for "Weapon".
* TheQuisling: Despite being of the original royal family that Zeba wiped out, he serves Zeba in hopes of succeeding him and restoring his family name.
* RaisedAsTheOppositeGender: [[spoiler:Was raised as male so she could claim the throne of Tube, as Tube tradition dictates only a man can take the throne. She keeps it up under Zeba so she can be named his successor.]]
* TheRival: Of Takeru, who he seeks to kill to restore his family's honor after Ial fell in love with him.
* RoyalBlood: Is a member of the original Tube royal family, before Zeba usurped them.
* SheIsTheKing: [[spoiler:Is actually a woman, something not even her own sister knows.]]
* SignificantDoubleCasting: Is played by Mina Asami, who also plays his sister Ial.
* SweetPollyOliver: [[spoiler:Is not a prince but actually a princess]].

A ninja from the Buyon Tribe who serves Baraba as his lieutenant.

* LightningBruiser: Known for his speed and is one of top generals of Tube.
* {{Ninja}}: An underground Ninja for Tube.
* NobleDemon: Though he is a fervent supporter of Tube and Zeba, Oyobu abides by something akin to a code of honor, to the point of refusing to aid Baraba in dealing with the Maskman as Baraba promised he would do so ''by himself''.
* TheReasonYouSuckSpeech: Gives a particularly scathing one to Baraba when he asks for his help in fighting Red Mask.
-->'''Oyobu''': I wanted to give you, the Earth Imperial Commander and hero of the Baluga Clan, the chance to have a final fight. However, you are nothing more than a coward.
* SuperSpeed: Noting for being able to run at lightspeed-like velocities.
* UndyingLoyalty: To Tube, to the point where [[spoiler:he willingly gives his life to ensure Zeba's plan to raise the underground castle succeeds]].

----
* AlasPoorVillain: [[spoiler:She dies protecting Igam, confirming that she's still loyal to her, despite hiding her true gender and attempting to overthrow Zeba]].
* AntiVillain: [[SlidingScaleOfAntiVillains Type I]]. Fu-Min's loyalty to Igam is extreme, but genuine that she sometimes showed even compassion to the frozen Ial. She also pretty much [[spoiler:[[HeroicSacrifice sacrificed]] her life so Igam can live and redeem herself]].
* DarkActionGirl: A skilled ninja and one of the top warriors of Tube.
* EvilCounterpart: To Haruka, both being female ninjas.
* {{Ninja}}: Like Oyo-bu she is an underground ninja.

----
* BatOutOfHell: Resembles an overweight bat.
* EvilGenius: He is incredibly wise and has a vast knowledge of Tube's history, having served even prior to Zeba's HostileTakeover.
* FatBastard: Is a noticeably portly fellow and is shown to be a massive supremacist who willingly aided Zeba's plans, including [[spoiler:keeping the truth of him being a mere Doggler Beast hidden]].
* HypercompetentSidekick: Is a gifted orator, a wise historian, and a skilled warrior when necessary. Notably, Zeba treats him a lot better than most of his other subordinates, never giving him the same BadBoss treatment he does Baraba or Igam, and seems to trust him the most out of all his minions.
* KilledOffForReal: In the penultimate episode he's felled by Galaxy Robo after doing his best to keep Zeba's secret hidden.
* MyCountryRightOrWrong: He seems to be loyal to whoever sits on the throne of Tube, even if they aren't of the Tube royal family and are an usurper like Zeba. Notably, he was even involved in the conspiracy to keep [[spoiler:Zeba's true identity]] a secret.
* NonStandardCharacterDesign: While his more animalistic design wouldn't look out of place for a MonsterOfTheWeek, it certainly stands out among the, mostly humanoid, generals of Tube.

----
* KarmicDeath: [[spoiler:Not the death itself, but the last thing he sees before dying is an unfrozen Ial - the woman he gave up everything to go after - embracing her lover Takeru.]]
* KnightInShiningArmor: Subverted. While he does save girls like one occasionally, his motto is "I always get what I want", which horribly clashes with the meaning of the trope.
* MurderTheHypotenuse: His desire for Ial brings him to blows with Takeru.
* TheRival: Of Takeru for Ial's affections.
* SealedEvilInACan: He was trapped inside of a "whirling Hell" before freeing himself.
