Bitch in Sheep's Clothing: 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 Dark and Troubled Past probably plays a part into this.
Squishy Wizard: Subject to change as she gains levels, depending on how you develop her.
The Stoic: 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 Heroic BSOD.
Can't Drop the Hero: 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.
Deadpan Snarker: Although not quite to the same level of deadpan or snarkiness as Milly reaches, Ashlynn tends to snark more frequently.
Implied Love Interest: 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.
Magikarp Power - 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.
Jerk with a Heart of Gold: 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.
The Medic: He joins the party knowing Heal and Midheal.
Overrated And Underleveled: 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.
Cutscene Power to the Max: 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.
The Rival: Acts this way towards the Hero for much of the game, which even seems to continue post Heel-Face Turn, if party chats are to be believed.
Hulk Speak: Lizzie *spit*... talk like this often... *slobber*
Magikarp Power: 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.
Mighty Glacier: 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.
Secret Character: Can be recruited by taking Terry to the Arkbolt prison after he is recruited.
One of the Dread Fiends. He is responsible for creating and spreading rumors of utopian paradise, the Isle of Smiles. In reality though, the Isle is a Lotus-Eater Machine where the prisoners are tortured for eternity.
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.
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.
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.
A mysterious, obscenely powerful demon that resides deep within the 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: Nokturnus is the one of the most preeminent superbosses in all of Dragon Quest. Even when he appears in other games, he's generally one of the toughest monsters around.
Curb-Stomp Battle: If you beat him in fewer than 20 rounds, he will singlehandedly take down Mortamor for you. He'll win without even taking any damage.
Evil Is Not a Toy: 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.
