!Tenkai Knights

!!Guren Nash[=/=]Tenkai Knight Bravenwolf (Guren Ogami)
->Voiced by: Creator/JohnnyYongBosch (English), Meguru Takahashi (Japanese)

* {{Adorkable}}
* AllLovingHero: Has shades of this, what with being a KindHeartedCatLover and kid who thinks recycling is good for everybody.
* AnimeHair: Guren's hair is red in the front and black in the back.
* BewareTheNiceOnes: Guren is one of the sweetest, most polite, helpful kids around. [[BerserkButton But don't get on his bad side.]]
* ChronicHeroSyndrome
* DatingCatwoman: Downplayed, he a lot nicer to Beni [[spoiler:even after learning she is Venetta]] though that doesn't stop Ceylan from calling her his girlfriend.
* {{Expy}}: That hair of his is VERY similar to [[VideoGame/MegaManZX Atlas]].
* GoodIsNotSoft
* TheHero: He's the real star of this show; he leads the group and the story is generally told from his perspective.
* HeroesPreferSwords: Guren receives a sword when he transforms into Bravenwolf.
* TheIdealist
* MissingMom: She's dead.
* NewTransferStudent: Guren transfers to a new school in the very first episode of the series.
* NiceGuy
* PlayingWithFire: Gets this power with the upgrade in episode 27.
* RedOniBlueOni: While all four boys have red oni and blue oni traits, it's more obvious with him and Ceylan[=/=]Tributon. Although it is color inverted, the red colored Bravenwolf is the blue to blue Tributon's red.
* WhenYouComingHomeDad: His father is frequently busy. There are days where he doesn't even come home at all, even though it's not like he works outside of town. This weighs on Guren, naturally.

!!Ceylan Jones[=/=]Tenkai Knight Tributon (Seiran Washizaki)
->Voiced by: Creator/ToddHaberkorn (English), AkemiKanda (Japanese)

* AnIcePerson: Gets this power with the upgrade in episode 27.
* BookDumb: Ceylan isn't very interested in studying.
* ClassClown: In fact, this is how and why Guren met him and became fast friends with him in the first place. Having said, Ceylan is in fact a very cautious soul, and quick to point out when something doesn't seem entirely kosher to him.
* TheCynic: In contrast to Guren's WideEyedIdealist.
* DeadpanSnarker: Ceylan, definitely. About half of his lines are said in a somewhat sarcastic manner.
* GogglesDoNothing: Wears goggles for style.
* TheLancer: He's the first to meet and become friends with Guren, and therefore he's closest to him. His jokester tendencies also contrast with Guren's more pondered nature.
* SadClown: Ceylan appears to suffer from self worth issues that have made him consider leaving the team on more than one occasion. Nevertheless he's appointed himself the team's "funny-man", trying his best to appear the carefree joker when deep down, he's anything but carefree.
* RedOniBlueOni: Color inverted. Tributon is blue yet is the red to the red Bravenwolf's blue.
* RefusalOfTheCall: Ceylan is at first overwhelmed by the responsibility of the universe hanging over his head and promptly decides to not continue fighting. [[spoiler: [[StatusQuoIsGod He changes his mind by the end of the episode]].]]
* YouGottaHaveBlueHair: Ceylan's a solid blue.

!!Chooki Mason[=/=]Tenkai Knight Lydendor (Chuuki Hachisuka)
->Voiced by: Creator/BrycePapenbrook (English), Creator/RisaTaneda (Japanese)

* TheAce: Still a NiceGuy though.
* BornLucky: Chooki is so mind-bogglingly lucky that it defies logic. He wins every game he plays. Ceylan attributes it to supernatural powers.
* ChildProdigy: In the field of sports.
* GenreSavvy: [[spoiler:Chooki knew trusting Beni too much would be a mistake, and he was right]].
* LovableJock: He's awesome at sports, which he frequently uses as analogy for all sorts of situations.
* ShockAndAwe: Gets this power with the upgrade in episode 27.
* TheSmartGuy
* SmartPeoplePlayChess: One episode shows him beating a much older man at chess.
* SoreLoser: Downplayed. He doesn't behave inelegantly, but he still takes it pretty hard when someone beats him at some sport, and is prone to brooding about it.
* TheStrategist: Chooki often comes up with the battle plans.
* ThrowingYourShieldAlwaysWorks: In his Titan mode, Lydendor's bladed shield becomes his main weapon over his flail.
* WiseBeyondHisYears: Is more level-headed than the other boys.

!!Toxsa Dalton[=/=]Tenkai Knight Valorn (Takusa Kameyama)
->Voiced by: Creator/BenDiskin (English), Maki Mizuma (Japanese)

* AscendedFanboy: Toxsa has always been into video games, so becoming a Tenkai Knight was easier for him to get a handle on.
* BigEater: Not really given much focus, but Toxsa eats a lot.
* TheBigGuy: Valorn is the bulkiest of the Tenkai Knights. Combined with Toxsa's personality, it makes him something of a musclehead. Toxsa, ironically, is the tiniest of the guys.
* BladeOnAStick: Weapon of choice as Valorn.
* BrattyHalfPint: Shortest and most obnoxious of the four.
* CloudCuckoolander: Toxsa is definitely the most ''cooky'' of all the boys.
* DishingOutDirt: Gets this power with the upgrade in episode 27.
* GeekyAnalogy: Often references things he did in a video game to what's happening at the moment.
* HotBlooded: All the boys are a little hot-blooded to a degree. But Toxsa is definitely ''the'' most hot-blooded of them all.
* LeeroyJenkins: At times.
* NonstandardCharacterDesign: Although his smaller size is justified given that he's a year younger than the others, Toxsa's eyes are much larger and rounder while his irises are much smaller.


->Voiced by: Creator/CrispinFreeman (English), YosukeAkimoto (Japanese)

* AllAccordingToPlan: Says it word for word after [[spoiler: his defeat in episode 13]].
* AuthorityEqualsAsskicking: A completely JustifiedTrope.
* BackFromTheDead: [[spoiler:Vilius is resurrected when he dies and proceeds to revive his dead henchmen afterwards.]]
* BigBad: Vilius started the war for Quarton and seeks the Tenkai Dragon. [[spoiler: While Gen had plans to overthrow him, Vilius sees through this and turns the tables against him.]]
* BigNo: When [[spoiler:the Tenkai Knights (plus Gen) defeat him in their new Phoenix Mode]].
* CardCarryingVillain
* TheCorrupter: A rather literal case, he has the ability to turn Corekai into the Corrupted.
* EvilOverlord
* EvilWearsBlack: A common trait found in the Corrupted forces.
* FallenHero: According to the official website, Vilius was once part of the Tenkai Knights himself, a highly respected part of the Corekai, until his greed got the better of him and he was cast out. It was then that he decided to overthrow the Corekai and eventually rule the entire universe.
* GenreSavvy: [[spoiler:Was smart enough to know Dromus might try to take the Tenkai Dragon's power for himself.]]
** Edges into DangerouslyGenreSavvy with his apparent plan to revive himself ''again'', this time using some form of control on the Guardians themselves to make them bring him back for some form of further punishment.

!!Granox (Brinox)
->Voiced by: Creator/SteveBlum (English), Hisao Ogawa (Japanese)

* AnimalMotif: Granox's design is meant to resemble a rhinoceros.
* TheBrute: Not known for his strategic genius.
* DirtyCoward: One thing he and Slyger have in common. When things get ''really'' bad, he gets going.
* EvilSoundsDeep
* GlassCannon: Granox seems invincible at first, but he goes down just as easy as Slyger once he's hit.
* ItHasBeenAnHonor: [[spoiler: Presumably attempts to tell this to Slyger, knowing that they might lose to Chooki and Toksa in their final showdown]]. Slyger was too full of himself to let him finish, though.

->Voiced by: Creator/CrispinFreeman (English), Atsushi Imaruoka (Japanese)

* AnimalMotif: While his speech and mannerisms seem to evoke serpents, Slyger's large claws [[spoiler:and Titan Mode]] goes with a cat/panther motif.
* BloodKnight
* DirtyCoward: Same as Granox.
* FragileSpeedster: He's faster than Granox, but not by much.
* SmugSnake
* WolverineClaws

!!Gen Kurai[=/=]Tenkai Knight Dromus (Gen Inukai)
->Voiced by: Creator/YuriLowenthal (English), MiyukiSawashiro (Japanese)

* BlowYouAway: Gains wind powers from [[spoiler:his Elemental form]].
* TheDragon
* EmoTeen: Gen has the appearance (although not the personality) of this. Lampshaded by Toxsa himself.
* EvilCounterpart: Dromus serves this to Bravenwolf, said same goes to Gen to Guren and in addition to being The Rival.
* {{Expy}}: Gen strongly resembles [[Manga/{{Naruto}} Sasuke]] with the hairstyle, clothing, personality, emo appearance (this is lampshaded by Toxsa himself), and even share the same voice actor, Yuri Lowenthal. He also works with Vilius under the guise of Tenkai Knight Dromus; and serves as TheRival and EvilCounterpart to Guren.
* HeelFaceTurn
* PerpetualFrowner: [[spoiler:Even after he joins the Knights, he does little smiling.]]
* TheQuietOne: Gen doesn't like to socialize with other people. This is because he is working with Vilius and prefers to work alone in secret.
* SixthRanger: [[spoiler:Joins the Tenkai Knights in "A New Knight" when he realizes that destroying both worlds isn't what he really wanted.]]
* TheStarscream: Gen's not even being subtle around Vilius about the fact that he's just using him to get the Tenkai Dragon's power for himself.
* TheStoic: He isn't really that emotional.
* StrawNihilist: [[spoiler:Whatever happened to his family caused Gen to become this and seek to destroy all worlds. Guren calls out how pathetic he is for it and makes Gen start to realize this.]]
* UsedToBeASweetKid: As seen in a flashback, Gen was able to smile once.

!!Beni[=/=]Tenkai Knight Venetta
->Voiced by: Creator/NikaFutterman (English)

* ActionGirl: As Venetta.
* CuteAndPsycho: Beni likes flirting with Guren and planning the utter annihilation of her own species, all in the same sentence.
* DarkActionGirl: Beni becomes one when she is Venetta.
* DarkChick
* FemmeFatale
* LadyOfWar: Venetta certainly is one of these.
* PinkMeansFeminine: Ceylan openly assumes that the newest Tenkai Knight must be a girl due to "Venetta" wearing almost completely pink armor. Chooki calls him out on his bias and tells him not to make assumptions. Turns out, Ceylan was right.
* WomenAreWiser: Seems to have this attitude since many of her insults involve things like "he's just a typical boy".

* CannotTellAJoke: Or trash-talk.

* HonoraryTrueCompanion
