[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/mk_hr_rohan.jpg]]

An orphan raised as Cathbad's apprentice before learning he was the long-awaited [[TheChosenOne Chosen One]] Draganta, making him the leader by default. He is the only one who can control Pyre, the Dragon of Dare, whom he summons with the Dragon's Breath Dagger.

** Element: Fire
** Mystic Weapon: [[HeroesPreferSwords The Sword of Kells]], a sword that shoots flames
----
* {{Adorkable}}

[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/mk_hr_angus.jpg]]

Rohan's best friend and roommate. The two grew up on the streets together, and Angus was -- and still is -- the troublemaker. Rohan trusts him unquestionably ([[ThePowerOfFriendship the power of their friendship]] was once enough to free Rohan from a spell), despite his reputation as a {{trickster}} and pickpocket. His skills in that area frequently come in handy.

** Mystic Weapon: [[EpicFlail Terra Mace]], a mace that shoots large boulders and creates earthquakes

[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/mk_hr_deride.jpg]]

The RebelliousPrincess of Kells, who finds herself a habitual blackmail tool. In the finale, it took all of one minute for Maeve to grab her and the knights to sulkily abandon their weapons as if it had become routine, which it had. Fortunately, [[FauxActionGirl no one in her world seemed to notice]], any more than they were bothered by her tendency to pull rank whenever she wanted to get her way. ("That's a royal command.")

* {{Princess}}
* RoyalsWhoActuallyDoSomething
* TheSmurfettePrinciple: Within the Knights.

!!'''[[color:blue:Ivar, Mystic Knight of Water]] (Justin Pierre)'''
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/ivar_mysticknightofwater.jpg]]

A prince who was passing through Kells on the hunt for a thief who stole a priceless chalice from his kingdom. He eventually learned that very chalice was located in Maeve's throne room, since it was Midar's portal between Earth and the Dark Fairy Realm. His dedication to retrieving the chalice almost matched his uncanny ability to track anything and everything.
** Element: Water
** Mystic Weapon: [[ProngsOfPoseidon Barbed Trident]], a trident that shoots streams of blue electricity.
----
* FourTemperamentEnsemble: Phlegmatic (water).
* ItsPersonal: Retrieving the chalice. [[spoiler:It gets even more personal when he learns it was Torc who stole it]].
* MakingASplash
* TheQuietOne
* RoyalsWhoActuallyDoSomething: Like Deirdre he comes form a royal family. Unlike Deirdre, he had to travel to another ''country'' in order to retrieve a magical item taken from his people. Now ''that's'' dedicated royalty.
* TheSmartGuy
* TheStoic
* TokenMinority
* WiseBeyondTheirYears

!!'''[[color:green:Garrett, Mystic Knight of the Forest]]'''
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/mk_hr_garrett.jpg]]

A SixthRanger who came to Kells to carry out his betrothal to Deirdre, who instantly shot him down due to his initial severe superiority complex. After a period of fighting the team after being {{Brainwashed}} by Maeve, Cathbad realized he was destined to be the fifth Mystic Knight. Deirdre firmly refused to go through with the marriage, but she tolerated him as a teammate, even giving him a kiss good-bye when he left almost as quickly as he came to escort a stranded princess home.
** Element: Forest
** Mystic Weapon: [[DualWielding Twin]] [[AnAxeToGrind Timber Axes]], which are supposedly "sharp enough to slice a stone in half," but were usually used to shoot energy blasts.

* EvilLaugh: Had one when he was evil.
* GreenThumb
* HeelFaceTurn
* PutOnABus: But when TheBusCameBack, he brought back A MechByAnyOtherName.

!!The Sentinels

Four guardians created by Mider to prevent the Mystic Armour from being claimed and used against Temra. After their initial defeats at the hands of the Knights they were assembled into a team and sent out to antagonize the heroes.
----
'''Tropes associated with the Sentinels as a group:'''
* BackFromTheDead: All appeared destroyed at the end of their initial appearances yet were resurrected by Mider and sent after the Knights again.
* BadassCape: All four wear long black capes as part of their outfit.
* TheBrute: They're a Brute squad of expendable but powerful muscle, sent out to harass the protagonists when Maeve and Torc are otherwise busy.
* EvilWearsBlack: All of them wear black, with or without another accent colour.
* ObviouslyEvil: All four are blatantly the bad guys, what with their spiked dark armours and ominous names.
* ThePsychoRangers: Each Sentinel is designed to oppose a particular knight. Assembled as a team, they became this.
* QuirkyMinibossSquad: Became this when Mider reassembled them as muscle for Maeve.
* SmugSnake: All four are given the same basic, overconfident, and condescending personality.
* SpikesOfVillainy: Dressed in spiky armour.

!!!The Ice Lord of Temra

The guardian of Rohan's armour, the Ice Lord is a skeletal figure wrapped in purple armour.
----
* AnIcePerson: Highly resistant to cold, he could also lower the temperatures of his sword, freezing those he touched.
* DisneyVillainDeath: His initial defeat leaves him plummeting off a cliff after Rohan melts the ice bridge they are fighting.
* EvilCounterpart: To Rohan, as a swordsman wielding the opposing element to his own.
* GrimUpNorth: The Mountains of the North, where he hides out, certainly evoke this.
* HornsOfVillainy: There are notable horns on his helmet and he's evil.
* MasterSwordsman: Within the confines of the show's ''extremely'' limited choreography budget, he qualifies, easily dominating Rohan, said to be the best swordsman in the show, throughout their initial fight.
* SecondaryColorNemesis: Rohan wears [[PrimaryColorChampion red and gold]], the Ice Lord purple.
* SinisterScimitar: Carries a frozen scimitar that gets colder on command.
* SkeletonsInTheCoatCloset: His armour is decorated with bones, including a ribcage on the breastplate.
* SkullForAHead: Whether it's his actual face or the mask of his helmet is questionable, but either way, the Ice Lord shows a bare skull to the world in place of a face.

!!!The Lightning Bat of Temra

The guardian of Dierdre's armour, the Lightning Bat comes armed with a magical boomerang and grating voice.
----
* EvilCounterpart: To Dierdre, as a sky-associated warrior for the other side.
* MakeMeWannaShout: His piercing shriek serves as his weapon of last resort, forcing Dierdre to her knees.
* WouldHitAGirl: He was up against Dierdre in his first appearance and targeted her afterwards for revenge.

!!!The Sea Serpent of Temra

The guardian of Ivar's armour, the Sea Serpent was a cackling sadist who held a grudge even better than the other Sentinels.
----
* AgonyBeam: The shocks from his whip could act as one at range.
* EvilCounterpart: Like Ivar he's associated with water, and he has the same ability to obsess over defeats.
* ItsPersonal: None of the Sentinels took their first defeat well, but the Sea Serpent seems to have taken his the most personally, returning to harass Ivar as both a member of the Sentinels and independently.
* PsychoElectro: Despite his name, his primary power was not based around water but electricity and he was one of the eviler members of the cast.
* {{Sadist}}: Probably the member of the Sentinels who most enjoyed causing pain.
* TheSavageSouth: Haunts the Southern Shore and is the main reason why it has a bad reputation.
* VillainTeamUp: Not only with the other Sentinels, but with Torc, whom he ganged up on Ivar with in an episode.
* WhipItGood: His primary weapon was his "Serpent's Tongue Whip" which emitted electrical shocks to those it touched.

!!!The Rock Wolf of Temra

The guardian of Angus' armour, the Rock Wolf was stupid, brutish, and completely uninterested in the world around him.
----
* DumbMuscle: None of the four were geniuses but the Rock Wolf was easily the dumbest.
* EvilCounterpart: To Angus, being associated with stone, none-too-bright, and relentlessly lazy.
* EyeBeams: Could fire rays of energy from his eyes.
* LazyBum: When Angus first showed up the Rock Wolf didn't even want to fight him and tried to just bluster him into going away. When Angus pressed the issue, the Rock Wolf settled for driving him off, then promptly retreating to his cave.
* RedAndBlackAndEvilAllOver: Wore black armour with red highlights.
* WolverineClaws: His awkwardly named "Wolf's Tooth Claw" which was fixed to one of his wrists and served as his main weapon.
