A young girl who declared her plan to conquer the Seven Worlds, because each world has unique beautiful features. And she wants them. She has two special abilities thanks to her title of "Undisputed God" — Peon Rebirth, which forces anyone/anything that likes, loves, adores or worships her into her obedient servants; and Form Change, which transforms her to match a different personality.
100% Adoration Rating: Kind of forced, but she is generally well-liked by her subordinates. Especially Ryuto and the Shampuru. The "Charm-Level" mechanic is partially based on this as well.
A-Cup Angst: Implied, if one of her level-up comments is any evidence.
"I wish my chest would level-up..."
A God Am I: Subverted. Turns out she was the Undisputed God after all.
Amnesiac God: Remembers nothing from before she appeared floating in space. Her memories are a plot point.
Anti-Villain: Type IV. She's not actively evil or malicious, but is conquering the seven worlds and can be a jerk at times.
Crutch Character: Many unique gameplay features are bound to her. Moe-Kill, Peon Ball, Peon Command, Form Change, etc. She can also learn almost every skill in the game, regardless of weapon type or affinity.
Demoted to Extra: Despite that she was the main character in the first game, she falls victim to this In the second game, where she loses her powers and gets shrunk to a tiny chibi version of herself, rendering her useless except to ride on Syrma and command her and explain her powers to her.
Determinator: Will not let anything stop her from conquering the Seven Worlds and everything in them.
Expy: Intentionally designed to be something of a female Laharl, more or less.
Hates Being Alone: She was tired of being alone in space, so she created her own world. She became even lonelier after realizing she was to be a mere observer, not a participant, in her world. Even her bio states she prefers good company over solace.
Take Over the World: Take over Seven Worlds, to be precise. Later declares her ambition to rule the entire universe.
Too Dumb to Live: At the beginning of Z, she ignores Syrma's warning about her coffin being dangerous, takes it from her and, what the heck do you know? It snatches her and she loses her powers and becomes tiny, rendering her useless.
The most mature-looking of Chou-Chou's seven incarnated personalities, and the most sadistic, not to mention with a vocabulary dripping with innuendo, sometimes with a backhanded compliment or veiled insult within.
Chou-Chou's shy personality, who tends to respond to any conversation made with her with a volley of apologies (and that includes the Shampurus). Often she'll jump headfirst into battle... if only to relish in the pain she will invariably receive from it.
The Nicknamer: Though the nicknames are often quite simple yet bizarre, and often longer than the original name. Altis is "Tes-Tes", Ryuto is "Hey-You", Soul is "So-So", Sandy is "San-San", Alys is "Al", Tsukika is "Kiki", Welsh is "Welloony", Sharuru is "Sharurururu", Marina is "Big Sis Rina", Dees is "Deedee", Shirogane is "Old Dude", and Elka is "Pervka".
Altis / Altalt-tistis
"I'm no Angel! I'm a Demon! A vile, wicked Demon!"
An angel who used to be a demon in a past life. Altis is so utterly clumsy that, during her life as a demon, she always ended up doing something good whenever she tried to stir up trouble, for one reason or another. Proving incapable of delivering desired amounts of evil, she was eventually reborn as an angel and booted out of the Netherworld. Not one to be discouraged by such a minor setback, she still spends her days plotting evil schemes in order to be reborn as a demon once more.In Z, she reemerges as "Altalt-tistis", a masked villainess and Kakeru's archnemesis.
Ascended Demon: Although like most examples she was not trying to be this.
Expy: To Artina, on account of both being gunslingers in skimpy outfits, with matching un-angelic behavior and the same English voice actress.
Butt Monkey: An amusing subversion — she thinks she's this by her own standards; to everyone else, she's a blessing.
Evil Overlord: She believes she can become this if she helps take over the world. To bad the universe has other plans.
Femme Fatale: Averted, she wants to be this but failed epically.
Foil: A company-wise version with Flonne, a flat-chested angel who became a demon for technically doing evil while trying to do good, though she doesn't mind the change. Altis is pretty busty, was a demon who became an angel without even intending to, and is annoyed with it.
Chou-Chou's first noteworthy vassal. He is the reincarnation of an interstellar ship, who hoped to wander the universe, but when reality fell short of his aspirations, he met Chou-Chou and instantly fell for her. Since then, he has become her loyal servant and is in charge of her ship's upkeep. He does not mind the labor, so long as he remains close to Chou-Chou.
Always Someone Better: This is his main struggle. Early on, he was the only non-Shampuru servant on the ship, so he was fairly useful as general handyman. But once more people who are as skilled as he is (if not better) start joining, he becomes increasingly useless. Soul outclasses him as a fighter, Elka as a pilot, and once they get enough people, there's little need to have one "sole" mechanic. He desperately wants to be useful to Chou-Chou, but it's difficult for a jack-of-all-trades like him.
Anti-Hero: Type I. Before becoming a peon, anyway. He's this by default.
Anti-Villain: Type IV, considering he'd do anything Chou-Chou told him to. At one point when Altis suggests that they may form an oppressive, tyrannical regime, Ryuto admits he'd still help if that was what Chou-Chou really wanted.
The Hero of Sun World (for a certain value of "hero"), Soul is skilled in both blades and magic. He can be a bit brusque and taciturn, but it is all to keep a level head. He is completely impressed with the "Hero who is me" and usually chooses the archetypical "heroic" way of doing things. In the midst of all that, he takes a special kind of pleasure in dressing his female party members up in swimsuits and forcing them to journey with him like that. For those and other reasons, his strength is recognized worldwide, though citizens also see him as a weirdo and, as such, he is not all that popular.
Celibate Hero: Zigzagged. He seems to care little about women's bodies, but is very quick to fit them in swimsuits. Soul lampshades this himself when Chou-Chou Sadist asked why he isn't getting into it like Sandy.
Disability as an Excuse for Jerkassery: Heroes are actually compelled to break into houses, rummage through strangers' stuff, and smash pottery. Most of the world and heroes view it as a mental affliction; he enjoys it. The only thing he enjoys more is being allowed to parade Sandy around in a bikini.
Hero with Bad Publicity: His power and deeds are revered, but the citizens of Sun World find him creepy, and justifiably so.
Ideal Hero: He believes himself to be this. Not so much in reality. In Mugen Souls Z Nao initially believes him to be one, becoming utterly infatuated with the Soul in her mind, as the group never bothered to get around to mentioning his "one terrible flaw".
Jerk with a Heart of Gold: You'd never know he's a hero with his abrasive, perverse personality. But when push comes to shove he can show that he is not so bad a person after all.
Kleptomaniac Hero: Parodied. Chou-Chou and Altis mistake him for a villain when they see him doing this.
-Princess (and Demon Lord) of Sun World. Until recently, Sandy was almost like a currency exchanged between different monsters looking to kidnap a princess, but she was eventually rescued by Soul. However, she is not allowed to return to her castle and, once rescued, has been forced to travel alongside Soul. Since then, she has been ill-treated by innkeepers, paraded around in revealing swimsuits, and has generally had a rough existence. She is elegant, clean, and obedient — the paragon of a princess. However, when she comes across her "type", her personality does a total 180°.
Damsel in Distress: In her past. Now under Soul's (and eventually Chou-Chou's) tutelage, she's actually learning to be a better fighter.
Fusion Dance: She's only technically a Demon Lord, due to the Sun World's actual Lord having absorbed her shortly before being defeated. That said, she does keep some of the latter's power, as well as the ability to sense other Demon Lords.
Oedipus Complex: She doesn't have anything against her father, but she really wanted her mother to do the same things to her she did to him. She's obsessed with Chou-Chou's Sadist personality because she's so similar to her mother.
The Heroine of Moon World, whose regular job is a miko. Shy and withdrawn, Tsukika does not perform many heroic deeds at all, and the residents of her world are not aware she is even their chosen one. This, together with her delicate frame, make the fact that she houses tremendous power all the more surprising. It is rumored she can even lift small mountains. Although she secretly respects Shirogane, whenever she runs into him, she becomes flustered and nervous, which ends up with his ass being handily beaten... somehow.
Badass Adorable: Managed to hand Shirogane his ass multiple times without even trying to.
Badass Family: In Mugen Souls Z she is effectively part of one with Shirogane and Reu. While initially jealous of the attention Reu was getting from Shirogane the three eventually settle into a family like relationship, a fact that does not go unnoticed by the other characters.
The Big Girl: While lacking in size, she is one of the most physically powerful members of the party.
Cannot Spit It Out: While she's pretty quick to admit it to anyone willing to tease her about it, mainly Altis, she just can not properly tell Shirogane that she likes him.
The Demon Lord of the Moon World, Shirogane is a manly and reliable father-figure for many. However, due to his title, grim appearance, and rough mannerism, those who meet him for the first time believe him to be an uptight, fussy, and all-around bad guy. However, he never preformed any particularly evil deeds and wandered blithely around his world until he met Tsukika. Since then, his life changed dramatically. Now, every time he runs into her, his ass is thoroughly beaten so often he fears this otherwise lithe waif. He no longer wanders around with joy, but creeps around in fear, in an effort to avoid confrontations with Tsukika.
Badass Family: In Mugen Souls Z he is effectively part of one with Tsukika and Reu. While Tsukika was initially jealous of the attention Reu was getting from him the three eventually settle into a family like relationship, a fact that does not go unnoticed by the other characters.
The Demon Lord of the Fire World and a famous idol. Because she is clearly craving for attention, she does her utmost to always be surrounded by adoring fans, which does not help her already low social well-being, and is somewhat of a crybaby. To stand out better, she wears fashionable outfits, but she does want to wear subdued, typical outfits every once in awhile. She is at the age where she is discovering who she truly is. Since her personality can be compared to Chou-Chou's, she sees her as a rival. Chou-Chou fails to think alike.
The Hero of Fire World isn't actually human. He's a demon. And a complete narcissist, at that. Elka is convinced every girls swoons upon seeing his manly charm, yet is anything but manly when faced with threats, fueling rumors that he's a cowardly loser. He has been spending quite some time trying to woo Alys, mostly in vain.
Jailbait Wait: While hanging around with Welsh, he notes that she's the only girl on G Castle that doesn't hate him and hopes that it'd stay that way for the duration of the "proper maturation period".
The Heroine of Water World, who doesn't even care for protecting her world as much as she does for exploring a ruins buried beneath layers of ice. While a skilled mage in her own right, she tends to screw up her spells terribly.
Demon Lord of Tree World and older twin sister to its Heroine, Welsh. As the least threatening of the Demon Lords, Sharuru tries too hard to look the part, only to end up making herself look too cute to be a threat to the world.
The Heroine of Metal World, whose brash personality matches with the dire situation of her home world.
Big Eater: She "eats" electricity, and has managed to blow G-Castle's fuses doing so.
Brick Joke: The "Heroes are compelled to smash vases" thing was more or less seemingly dropped after Moon World. Towards the end of the game she accidentally smashes Elka in the face with a vase she threw, and immediately admits to having no idea why she feels the need to destroy them.
Loving a Shadow: For awhile. She was instantly smitten with Soul, between the descriptions of him given managing to omit his bikini fetish while playing up his otherwise perfect heroic personality and her first encounter with him managing to avoid the fetish coming up as well. She rushes the group along to save him from Supra, but once they finally meet again and she learns the whole fight between Supra and Soul was over a bikini, her opinion drops dramatically, going so far as to stop addressing him as "Sir Soul" and simply call him "that guy".
"I'm not gonna hold back any longer. I'll kill you right here and now!"
The Ultimate God of Scarlet (Leo) World, who appears to be a feral, energetic little girl.
Badass Family: She is effectively part of one with Shirogane and Tsukika. While Tsukika was initially jealous of the attention she was getting from Shirogane, and attempting to keep Shirogane to herself, the three eventually settle into a family like relationship, a fact that does not go unnoticed by the other characters.
Cheerful Child: Whatever the time, place and occasion, she's always seen horsing around.
Expy: of Neptunia V's Peashy. Young adorable girls who are both hyper, always happy, and super strong despite their size.
Overly Long Name: Her actual name is said to be one, and all she can remember are the first three letters of her name, thus "Reu".
