!!!The Main Character

* TheAce: Like most Dragon Quest heroes, he grows into this as the game goes on.
* AnimeHair
* BashBrothers: Carver's party chats with him seem to suggest this kind of relationship between the two.
* CantDropTheHero
* ChickMagnet: Plenty of ladies show interest him throughout both worlds.
* CombatMedic
* {{Expy}}: Looks like a palette swapped [[DragonBall Gohan]].
* HelloInsertNameHere
* HeroicMime
* TheHero
* JackOfAllStats: Although his early acces to the Hero class makes him become a LightningBruiser towards the end of the game.
* MrFanservice: Shows more skin than any other Dragon Quest Hero, and is clearly quite well-toned.
* PrecisionGuidedBoomerang: Is able to wield boomerangs at the beginning of the game.
* [[spoiler:RoyalsWhoActuallyDoSomething]]
* ShipTease: Some with both Tania and Ashlynn. [[spoiler:He gets even more with Ashlynn in the ending.]]
* [[spoiler:StarCrossedLovers]]: [[spoiler:Seems to become this with Ashlynn during the ending.]]
* YouGottaHaveBlueHair

!!!Carver

* BareFistedMonk: Seems to be geared towards the Fighter class initially, though the player can mess around with this somewhat.
* BashBrothers: His party chats with the Hero imply that they're this.
* TheBigGuy
* BookDumb: Tends to have a somewhat blue collar take on higher learning.
* BoisterousBruiser
* DubNameChange: Hassan became Carver.
* DumbMuscle: He is not stupid, but he can be slow to catch on sometimes.
* FamilyBusiness: Ran away from being a carpenter to be a wandering martial artist. [[spoiler:Retires in the end to take up his father's trade.]]
* FireForgedFriends: Initially the Hero's rival for the title of guardsmen, the two of them put aside their differences and team up and become inseparable from there on out.
* GentleGiant
* HeelFaceTurn: While not ever a villain, he goes from a bully to an ally in the early parts of the game.
* JerkWithAHeartOfGold: Initially kind of a dick to the Hero, once they join forces he becomes his best friend and an all around nice guy to be around.
* MightyGlacier: Excellent HP and strength, but rather slow.
* UndyingLoyalty: Towards the Hero, which really shows in his late game party chats.
* YouGottaHaveBlueHair: It's pink, actually.

!!!Milly

* ActionGirl
* BitchInSheepsClothing: Somewhat. While Milly is a nice person, she tends to be quite snarky around some of the more obnoxious characters the party works with and also appears to be the one most willing to go to extremes to accomplish goals. Her DarkAndTroubledPast probably plays a part into this.
* TheChick
* CoolBigSis: Functions as one to the entire party. [[spoiler:Is actually one to Terry]].
* DarkAndTroubledPast
* DeadpanSnarker: She has plenty of this if you pay attention to her party chats, generally in the form of back-handed compliments.
* DubNameChange: Mireyu became Milly. She was Milayou in [[VideoGame/DragonQuestMonsters Dragon Warrior Monsters]].
* {{Expy}}: Looks more than a little like [[DragonBall Android 18]].
* FortuneTeller
* GreenEyes
* GuestStarPartyMember: At first. She soon joins the party for good.
* AnIcePerson: She learns ice spells naturally.
* [[MarthDebutedInSuperSmashBrothers Milly Debuted in Dragon Warrior Monsters]]
* TheMedic: She joins the party already knowing healing and buffing spells.
* [[spoiler:ParentalAbandonment]]
* SpellMyNameWithAnS: Mireyu/Mireille/Muriel/etc... The localization went for 'Milly'.
* SquishyWizard: Subject to change as she gains levels, depending on how you develop her.
* TheStoic: Tends to keep a pleasant calm through most situations, making her both a great Team Mom and Deadpan Snarker. This goes away if you take her to Felonia, where she gets thrown into a mini HeroicBSOD.
* TeamMom: Implied through party chats.
* [[spoiler:YouCanSeeMe: She is able to see the hero and Carver when they arrive in the dark realm.]]

!!!Ashlynn

* ActionGirl
* BigEater: An informed ability, since we only hear this through party chat.
* [[spoiler:ButNowIMustGo]]
* CantDropTheHero: Strangely, this applies to Ashlynn as well as the Hero, despite the fact that all events involving her are optional, and, like even the Hero, it is optional to have her in the main party of four.
* DeadpanSnarker: Although not quite to the same level of deadpan or snarkiness as Milly reaches, Ashlynn tends to snark more frequently.
* DubNameChange: "Barbara" in the Japanese version.
* {{Expy}}: Bears quite a resemblance to [[ChronoTrigger Marle]], and by proxy [[DragonBall Bulma]]. She's also similar in design and attitude to [[{{Slayers}} Lina Inverse]].
* FieryRedhead
* GenkiGirl
* GrayEyes: At least in her artwork.
* HairColorDissonance: Her hair sometimes looks more blonde than red.
* ImpliedLoveInterest: Due to the game's lack of complex character interaction and the Hero's lack of any dialogue, the most romance she has with the Hero comes in the form of several flirty party chats.
* TheLancer
* MagikarpPower - Ashlynn is extremely weak at first, especially if you make her first vocation a Mage, but with enough work and patience to make her a Sage (and possibly Armamentalist), she becomes the best spellcaster in the game, with devastating offensive spells and healing spells on par with (or possibly even exceeding) Nevan.
* MiniDressOfPower
* PlayingWithFire: She learns fire spells naturally.
* PurpleEyes: In-game at least.
* QuestForIdentity
* RedHeadedHero
* ShipTease: With the Hero. [[spoiler:They become StarCrossedLovers in the ending.]]
* SpiritedYoungLady
* SquishyWizard: At first. She can be made into a much better fighter later.
* [[spoiler:StarCrossedLovers]]: [[spoiler:Seems to become this with the Hero during the ending.]]
* {{Tsundere}}: Mostly dere dere around the Hero and the rest of the party, but gets tsun tsun around annoying people i.e. Terry.
* ValleyGirl: Talks like one relatively frequently.
* WhipItGood
* YouCanSeeMe: When you first meet her.

!!!Nevan

* {{Adorkable}}: After traveling with the party for a while and becoming nicer, Nevan's naivety quickly puts him into this territory.
* BaldOfAwesome: Without his hat on.
* BlowYouAway: He learns wind spells naturally, like a priest.
* BrattyHalfPint: Initially at least. He gets better after spending some time with the party.
* ChildMage
* ChildProdigy: Apparently, he's the young prodigy of Ghent Village, but it is never explained in what sense this is in.
* DubNameChange: From Chamoro to Nevan.
* JerkWithAHeartOfGold: At first, he and the Elder blow off King Somnius's request to aid the party, with more than a hint of arrogance. Then he gets a message from a higher power and immediately changes his tune, spending the rest of the game as a humble and and kind person.
* TheMedic: He joins the party knowing Heal and Midheal.
* NiceHat
* OracularUrchin
* ParentalAbandonment
* RaisedByGrandparents: It's never really explained what happened to his parents.
* ShorterMeansSmarter: The shortest party member is also The Smart Guy.
* TheSmartGuy
* SquishyWizard: Only at first. Later that can be changed.

!!!Amos

* BornUnlucky: [[spoiler:Cursed to turn into a monster when you first meet him and it only gets worse from there.]]
* ButtMonkey: Party Chats with him imply that he has terrible luck, and he tends to be the butt of the other party member's jokes.
* ChivalrousPervert: Old Amos likes the bunny girls and frequently laments his single status.
* DumbMuscle: Shown to be pretty dense, but still a strong fighter.
* [[spoiler:InvoluntaryShapeshifter]]: His problem when you first see him.
* MightyGlacier: Quite similar to Carver in this regard, although he trades power for a wider equipment pool.
** [[spoiler:VoluntaryShapeshifter]]: What happens after you help him out.
* OptionalPartyMember
* ThirdPersonPerson: Old Amos refers to himself this way a lot.
* YouALLLookFamiliar: In a similar case as [[VideoGame/DragonQuestV Tuppence]], he looks like a generic NPC blue warrior in the original game. The remake gives him an updated, though still similar sprite.

!!!Terry

* AntiHero
* AntiVillain: Before his HeelFaceTurn at least. Then he becomes an AntiHero.
* ArrogantKungFuGuy: Has shades of this.
* {{Bishonen}}: Easily the prettiest boy in the game, although looking in a mirror as him reveals him to have preferred to have been a rugged manly man as opposed to a slender pretty boy.
* ChickMagnet: Girls all over the world are pining for him. [[spoiler:Even dragons, apparently]].
* DarkAndTroubledPast
* DeadpanSnarker: Unlike Milly, who tends to snark through witty back-handed compliments, Terry's snarking is blunt and biting. [[spoiler:Snarking must be a family thing.]]
* [[spoiler:DealWithTheDevil]]
* DefeatMeansFriendship: Only joins the party after getting defeated by them, and is the only party member to do so.
* {{Expy}}: Is literally [[DragonBall Trunks]] in a hat.
* HeelFaceTurn
* HiddenDepths: Party chats imply him to be a SupremeChef.
* JackOfAllStats: His stats are pretty similar to the Hero's, though he lacks early access to the Hero class.
* JerkAss
* ImprobableWeaponUser: Orihalcum Fangs.
* IneffectualLoner: Terry subverts this, as he's actually a talented swordsman who can stand on his own. [[spoiler:Eventually, however, he winds up playing this straight following his deal with the devil.]]
* [[MarthDebutedInSuperSmashBrothers Terry Debuted in Dragon Warrior Monsters]]
* MasterSwordsman
* OverratedAndUnderleveled: Terry suffers from this; while stated to have defeated several guards that you took down as a party and was shown to easily beat a very strong monster by himself, by the time he joins, he is more or less an average party member with an advanced job and strong weapon.
** CutscenePowerToTheMax: He uses Dragon Slash to end his fight with the monster in Wayfarer's Pass, but later joins you as a beginning Gladiator who doesn't yet have that skill.
* TheRival: Acts this way towards the Hero for much of the game, which even seems to continue post HeelFaceTurn, if party chats are to be believed.
* TheSixthRanger: Fits this trope perfectly, from starting as the IneffectualLoner rival of The Hero to becoming a RivalTurnedEvil to joining the party through DefeatMeansFriendship.
* UsedToBeASweetKid: Life was certainly not kind to him growing up.

!!!Lizzie

* AllAmazonsWantHercules: Develops an interest in Terry after he defeats her, and becomes his loyal follower from there on out.
* AnAxeToGrind
* [[spoiler:BackFromTheDead]]: [[UnexplainedRecovery Never really explained]], and it freaks out the guards.
* BreathWeapon: Learns the fire-breathing attacks by default, and starts off in the vocation that teaches these types of attacks.
* DinosaursAreDragons: She's a Hackasaurus who has a default class of Dragon.
* DumbMuscle: Implied by her Party Chat, though her Wisdom is actually fairly high.
* [[spoiler:HeelFaceTurn / IFightForTheStrongestSide]]: She was originally [[spoiler:the Hackasaurus that terrorized Arkbolt]], but it's implied she was impressed by Terry's skills and wanted to accompany him.
* HulkSpeak: Lizzie *spit*... talk like this often... *slobber*
* MagikarpPower: Inverted. Lizzie's stats when she joins at level 5 are on par with characters 25-30 levels higher than her, but she levels up '''very''' slowly and gets paltry stat upgrades until she breaks level 46 and up.
* MightyGlacier: The strongest and toughest party member around, even beating out Carver. Her Agility isn't even that bad, though it's still her weakest stat, and her HP and Resistance stats are the strongest in the game, with an impressive array of monster resistances and immunities on top of that.
* SecretCharacter: Can be recruited [[spoiler:by taking Terry to the Arkbolt prison after he is recruited]].
* StalkerWithACrush: Some party chats imply that she's one of these towards Terry.
* UndyingLoyalty: Towards Terry, whether he likes it or not. This thankfully extends to the rest of the party while he's with them.

!!!Murdaw

The Dread Fiend responsible for the monster hordes ravaging the world. [[spoiler:In reality, he is an agent of Archfiend Mortamor, sent to extend his reign from the Dread Realm into the human and dream worlds.]]

* BalefulPolymorph: [[spoiler:Turns the queen of Somnia into an amnesiac, insomniac version of the king and turns the real king of Somnia into a decoy of himself.]]
* BigBad: [[spoiler:NOT!]]
* [[spoiler:DiscOneFinalBoss]]
* [[spoiler:TheDragon]]
* TurnsRed

!!!Jamirus

One of the Dread Fiends. [[spoiler:He is responsible for creating and spreading rumors of utopian paradise, the Isle of Smiles. In reality though, the Isle is a LotusEaterMachine where the prisoners are tortured for eternity.]]

* DarkChick
* LightningBruiser
* [[spoiler:LotusEaterMachine]]
* WakeUpCallBoss

!!!Gracos

An aquatic Dread Fiend that sows chaos in the human world's oceans.

* TheBrute
* ProngsOfPoseidon

!!!Dhuran

The final and most powerful of the Dread Fiends. Using the floating fortress Stormsgate Citadel, he plans to succeed where his colleagues failed to subjugate the world. Despite this, he is oddly polite and courteous.

* AffablyEvil: He'll even heal you before his fight.
* [[spoiler:DealWithTheDevil: Gives Terry "ultimate power" in exchange for his service.]]
* EvilGenius
* [[spoiler:GracefulLoser]]
* NobleDemon

!!!Blackmar

The warden of Gallows Moor, the Dread Realm's infamous prison. When one of the Archfiend's subjects refuses to break under his tortures, they are sent to Gallows Moor, where Blackmar and his minions subject them to horrific tortures and inhumane treatments before finally mass executing them.

* TortureTechnician

!!!Archfiend Mortamor

[[spoiler:The master of the Dread Realm, and the true villain of the game. He is responsible for the crimes of the Four Dread Fiends, and created the 'link' between the human and dream worlds in order to conquer them both. His ultimate plan is to utterly remove hope from the hearts of everyone, transforming all three worlds into a bleak, soulless haven for despair and death.]]

* [[spoiler:BigBad]]
* [[spoiler:EvilOldFolks: His first form]].
* [[spoiler: FinalBoss]]
* [[spoiler:OneWingedAngel: Two of them.]]

!!!Nokturnus

A mysterious, obscenely powerful demon that resides deep within the [[BonusDungeon Fungeon]]. He respects only the strong, and if summoned, he will perform one wish for the summoner if they pass muster. If they don't... bad things happen.

* BadAss: [[spoiler:If you beat him in fewer than 20 rounds, he will singlehandedly take down Mortamor for you.]]
* BloodKnight
* BonusBoss: ''The'' BonusBoss of the VideoGame/DragonQuest series. He has all the strongest attacks in the game and more HP than all of [[spoiler: Mortamor's]] forms combined.
* CurbStompBattle: [[spoiler: His fight with Mortamor, he'll win without even taking any damage.]]
* EvilIsNotAToy: [[spoiler:In the backstory, a king summoned him in an attempt to stop Mortamor. The fact that, when you find that kingdom, it's a blasted, ruined wasteland full of poisonous swamps should tell you how well things went.]]
* WildCard
