Mythology Gag / Expy: To Bartz. They are both Idiot Heroes who happen to look similar and even dress somewhat similar except Sol wears read and Bartz wears blue as Freelancers.
Right Handed Mirror: To Nacht. Both are orphans chosen by the Crystal and both choose to be heroes, but Sol is the leader of the Warriors of Light and nearly Nacht's total opposite in personality and appearance.
Totally Radical: Sol uses modern slang awkwardly, such as commenting on "one epic airship."
The hero of the Kingdom of Lux, and Diana's older brother. Glaive and Sol are his apprentices. He expects to be recruited by the Imperial forces for his skills.
Meaningful Name: "Aigis" means benevolent protection. The character starts with the Cover ability, which causes him to jump in front of characters with low hit points and take the hit for him. He is also the hero of Lux, and implied to protect the area from threats.
Meaningful Name: Dusk is halfway between day and night, indicating his history with Nacht and Alba, Warriors of the Dark, and his current status as a Light Warrior. It also doubles as Theme Naming with his Polar Opposite Twin Alba, whose name means "sunrise".
The Mole: To the Empire. Revealed early on, although who he is a mole for remains a mystery for some time.
The Stoic: Nacht is described in his introduction as emotionless. He doesn't react too much. Doesn't talk much, either. Even when faced with dirty magazines, he does little more than blink at them. The most he ever seems to emote is when the subject of his homeland, Falgabard is at hand. And even then, it's mostly expressed with a slightly different sort of silence.
"An emperor must be the absolute symbol of the land, feared by one and all. The position exists beyond the realm of age and death, like a god among mortals. My people have always been ruled by an emperor since time immemorial. But I hungered for more than temporal power. I wanted the strength of the Crystals to defy death itself and reign until the very end of days!"
A self-proclaimed wandering prophet. He's looking for the rising of the Light Warriors, so he can help and protect them.He is actually the Emperor, and he seeks to use the power of the crystals to become a god and cheat death. The crystals themselves sense this and attempt to keep him from gaining them all, and by game's end he is almost successful...that is, until he loses his control over the Nil and is absorbed, becoming ChaosElgo.
A God Am I: Wants to become a living, immortal god by claiming all of the Crystals, and will even resort to fighting the heroes himself for that very reason.
Expy: He's quite similar to Exdeath as the Emperor, no? Right down to using something similar to the Void, and even being taken over by it. Being turned into an unholy, hideous Eldritch Abomination in the process (and therefore the Final Boss) helps, too.
Heroic Sacrifice: Twice. First he jumps in front of an attack that would have finished the party, taking 9999 damage. Then he somehow gets up and grabs the helm of the out-of-control airship, giving the party time to escape before finally dying in the fiery crash.
A world-famous bard from the port town of Rusalka. He has fallen in love with a mermaid.
Interspecies Romance: At least, that's what you're meant to think. She's actually his mother, and they both know it.
Involuntary Shapeshifting: Not once, but twice. When we first meet him he's been transformed into a frog, but in his backstory he is a merman transformed into a human to save him from a childhood disease.
Heel-Face Turn: Thanks to her memory loss, she becomes an ally of the party and comes to view Sol and Sarah as surrogate parents.
Hello, Insert Name Here: As she has no memory of her real name, Sol and Sarah decide to give her a new one for the time being. There actually is no default name. The Warriors refer to her as that name for the rest of the game, while Dr. Lugae continues to use the name "Argy".
Jack of All Trades: As a Memorist, she can replace all her battle commands with a random selection chosen from those she already knows. She can also equip all weapons and all armor.
Magic Knight / Combat Medic: As a paladin, he fights with a sword and gets holy sword techniques. He also gets access to White Magic up to level 4.
Meaningful Name: Gawain was the greatest of the Knights of the Round table, was portrayed as a brash warrior who was fiercely loyal to his king and country, and was known as the Maiden's Knight. That describes this Gawain to a T, especially his vow to protect Princess Sarah.
Sole Survivor: At least, so he thinks. He's overjoyed to find Sarah survived, too.
Hello, Insert Name Here: Unlike most of the guests. When he joins the party, he doesn't remember his own name, so the party (and thus the player) comes up with a temporary name to refer to him by. "Gramps" is the default.
Heroic Sacrifice: He jumps in front of Asmodai's magic blast to save his wife and son, and then uses a suicide attack to take down his barrier so the Dark Warriors can finish him.
Cast from Hit Points: Darkness and Onyx Wave consume one third of his max HP to use. Last Resort is sort of a roundabout form of this: it massively improves his stats, at the cost of killing at the count of 10.
Empathic Weapon: He is one. The suit of armor being an empty shell controlled by the sword. Even after losing command of the armor, the sword can still speak, remains with Nacht, and acts as a fifth member of the party, albeit no longer controllable as a party member.
Heroic Sacrifice: Kind of. He loses control of Sigurd's armor as a result of the massive amount of damage he takes on protecting the party from Baugauvan. The sword he's possessing still exists, however.
Defector from Decadence: Upon learning his clan sided with the Avalon Empire, and realizing how far from their values they've derailed with the attack on the kingdom of Burtgang, he's remained in hiding since rebelling against his clan's unethical choices.
Dual Wielding: In the flashback to the attack on Burtgang, he has Dual Wield ability. In the present day, he can't exactly do that, due to having only one arm.
Handicapped Badass: He lost his right arm after Gawain injured him in Burtgang, but has "mastered swordsmanship", to the point that he now deals more damage with one arm than most of the party can deal with any of their swords.
Left-Handed Mirror: To Tobikage. Both are adopted sons of the Elder, but while Jinnai defected after learning his clan was working for the Empire, Tobikage stayed and embraced their new ideology. Interestingly, this split happened right after Jinnai lost his right arm, forcing him to become left handed.
Shows up to save Edna from Styx in the nick of time.
And then again to save Glaive from being killed by Imperial soldiers.
And again to save all four Dark Warriors from Cocytus.
Heroic Sacrifice: Three times. First, he defends the Warriors of Darkness from Cocytus, then he performs what appears to be a self-sacrificing move in order to restore health to the Warriors as they fight Chaos Elgo, and then his spirit helps to hold back the tide of light from the exploding Nil.
Literal Split Personality: The Mask is Elgo's self-doubt and morality made manifest, and was split from him when the Crystal shattered the world in two.
Tin Tyrant: His armor calls Exdeath to mind, among others. However, you never fight him in the armor. The party attacks an empty suit of armor they are led to believe contains the Emperor. When they face the Emperor for real, he is wearing the same Red Mage outfit he always has been.
A Magitek scientist working for the Empire. He is the creator of Argy.
The Cavalry: Comes back from the "dead" to save the party in his airship in the nick of time.
Disney Death: Chooses to stay aboard his sinking ship because he refuses to leave his "daughter's" body. The ship sinks beneath the waves and everyone believes him to be dead... Until it rises up again as an airship later in the same chapter.
Meaningful Name: Asmodai is a powerful demon in Christian mythology. He is said to be a king among demons and punish adulterous men. The character disguises himself as King Feyr, and his treatment of the real King Feyr, a Handsome Lech, could be seen as a kind of punishment.
Meaningful Name: Styx is a river that borders Hades. Any oath sworn on the Goddess Styx had to be honored, and usually led to the death of a loved one in most myths. This character is associated with the water element and twists her promises to make things worse for the petitioner.
Meaningful Name: In Dante's Divine Comedy, Cocytus is the innermost circle of Hell and is a frozen lake. It's home to three sections: Caina for traitors to family, Antenora for traitors to country, and Ptolomea for traitors to guests. Very appropriate, seeing as how all three happen in the arc she's introduced in.
Imperio of the Light
One of the four divine generals, with the power of light. He seems to have the position of the Emperor's right hand.
Affably Evil: to contrast with the violent Shango or icy Cocytus, he is very polite, and treats the Warriors like "honored guests" when they approach Avalon Castle. He even asks politely for them to offer the Crystals to the empire before defaulting to battle when they refuse.
Light 'em Up: Wields the power of light in battle, obviously.
Light Is Not Good: He is endowed with the power of light, but he is firmly on the side of the Empire.
Meaningful Name: "Imperio" is Spanish for "empire". A fitting name for the man who acts as the de-facto leader of the empire when the Emperor is too busy.
Superpowered Evil Side: When the battle begins to go poorly for him, he transforms into Gehenna of the Darkness. More of a differently superpowerd, more evil side, really.
Memorists can use all abilities known by the character, but there is a catch. Using the Memorandum ability replaces all of a character's battle commands with those randomly chosen from commands they know.
Jack of All Trades: A Memorist can use any ability in the game, provided you've learned them. They can also equip any weapon or armor.
Magikarp Power: In order to get full utility out of this class you'll need to level other jobs first.
