Heroic Neutral: Asellus just wants to live her life with White Rose. The problem is that, first, Orlouge considers White Rose his personal property, second, Ciato wants Asellus eliminated as a threat to his power, and third, Rastaban wants her made into a Mystic who can overthrow Orlouge. She has a lot of Mystical asses to kick if she wants to be able to do this.
Power Dyes Your Hair- When she uses her Mystic abilities, 'Mystical Change' activates and adds the stats of the absorbed monsters onto her own— this change is signified by some glowing, floating, and her hair turning from green to bright blue.
Jerk Ass- He just sits in his suite on the Cygnus when it's attacked, refusing to help Red because of his name. On his own quest, if swallowed by Tanzer, he ignores the attack by Nomad's fighters against the other passengers, and abandons Fei-On in Tanzer's stomach. He also kills Kylin to take his gift of space magic, even if it meant doing so would cause the destruction of his paradise he made for children (some of his party members even call him out on this).
Broken Bird: Emelia was about to live a happy life with her fiancee, Ren, but that was brutally ripped away from her and was jailed soon after.
Clothes Make the Superman: Being an ex-supermodel, Emelia can get stat boosts in her clothes. Two of her four outfits give a minor benefit in a different skill. More specifically, they swap her "Spark Talent List"—that is, the moves she's most likely to learn, with the other ladies of Gradius.
Pink Tiger outfit boosts her barehanded attacks by swapping her list with Liza's
Bunnygirl outfit was likely meant to boost her magic skills, but has no effect.
Belly Dancer outfit boosts her sword techniques by swapping her list with Annie's
Soldieress outfit was likely meant to boost her gunplay, (possibly by swapping her hidden gun/magic stat (0) with Roufas (6)) but does has no effect.
Wrongly Accused- Accused of murdering her fiance, Ren. Unfortunately for her, Ren was Fuse's best friend, so he had her thrown into Despair with no trial.
The Alcoholic- Not as bad as Gen, but he has shades of this- He's always found in the Pub in Scrap, and during his story, if you do the quest for the Grail Card, finding the card becomes an afterthought to "Free sake!"
All Your Powers Combined - Essence states that his quest was finished last, mainly because he was so busy helping out all the other characters. So they returned the favor and all joined him to finish his quest. All of them. The villain of his story is also revealed to be the Man Behind the Man behind most other villains in the game.
Basement-Dweller- Actually starts off his quest because he's tired of being a burden to his mom (read: he gets kicked out.)
Lazy Bum- Starts as of these, and he's forbidden from going back home until he gets a job. His intro outright calls him "shiftless." In the end he's running Trinity after killing off Mondo and usurping his position. He winds up in hiding back home away from everyone.
Magikarp Power- He starts out with, essentially, no abilities to speak of, but can be developed to any level in any direction, and learns skills unusually quickly.
Magnetic Hero- Always found in the pub in Scrap, gets the other hero to talk about their self, and winds up joining their team. In his own story, he's genuinely friendly to anyone and gets people to join his team easily. In-game, he's got a very high "Charm" stat.
Walking the Earth- He leaves home in search of adventure. Adventure and a decent job.
Rednote Retsu Okonogi
Anime Hair- A few drug users comment on it, calling him "Cactus Head". Also, Doll finds it easy to find him due to his "hip-hop hairdo".
Crutch Character- Alkaiser form. While few non-bosses can stand up to his immense power, ending a battle as Alkaiser voids any stat bonuses that Red would get. Since Red's stats directly influence Alkaiser's, the result can be a very weak superhero.
Emergency Transformation- After nearly being killed by Shuzer, he's turned into a superhero by Alkarl in order to save his life.
Expy- His appearance appears to be based off that of a character named Red in a little-known Square Soft game called Treasure Hunter G. There's also a Blue in that game, although he looks nothing like this one's.
Dead Partner- Ren, Emelia's fiance, was his partner and best friend from way back in their academy days.
Demoted to Extra- Was originally going to be one of the main protagonists, but his quest had to be cut due to disk space.
Jerk Ass- Knocks Red unconscious for talking out of turn, gets Emelia thrown in Despair with little evidence because he doesn't like her, insults Lute a bit... he's not a particularly pleasant individual.
The Alcoholic- A full-blown drunk. Just sits around getting wasted in Scrap and Junk, and both his status screen and victory pose involve him drinking.
Cool Old Guy- Has the personality, and at age 35, he's definitely this to Rose(14) and Thyme(12). To everyone else in-game, he's borderline- none of the protagonists are older than 25 (Lute), and short of Roufas(40) and Capt. Hamilton (48), he's still got 6 years on the next closest character who can join the group.
Drunken Master- A drunken samurai, and possibly the best sword user in-game.
Implausible Fencing Powers- He cuts through a rope by using an iron pipe as a sword, although he later claims he didn't use the pipe to cut it. Lampshaded by T260, who Divides By Zero trying to figure it out.
Cool Shades- Never takes 'em off. Not even while cooking. Not even at a wedding.
Rated M for Manly-When you run into him at Mu's Tomb looking for the Victory Rune. He'll only join human, male characters who answer with a Testosterone Poisoned "YEAH!!" when asked if Victory is the mark of a real man.
Happiness in Slavery - She's quite eager to be Asellus' slave when Asellus comes back to her. Averted with the Lord of the Manor; she's not happy at all when he confines her to his house.
I Owe You My Life- If Asellus goes back to Owmi for her after the Dark Labyrinth, Mesarthim invokes this trope, insisting that she be Asellus' slave. Incidentally, she also feels this way about the Lord of the Manor, but can't stand the constant smell of humans or her confinement in his shower.
The Voiceless- It's rumored that he lost his voice when trying to absorb Tanzer, although Word Of God says he's a natural mute. Under the right circumstances, he'll speak in Red's game near the end, but it's in a scene where the second and third members of the group ask Red-as-Alkaiser about where Red is, so it's likely just an oversight or glitch.
Power Perversion Potential- Invoked in Essence when he uses Time Leap to allow Fuse to feel up Doll. Unfortunately, since the person is outside of time, they can't be affected by anything, and feel as hard as stone. Unfortunately for Fuse, Time Leap's effect doesn't last very long.
Bi the Way: She's attracted to the Charm Lord, whether they're male or female. She was previously Orlouge's princess, and is still somewhat loyal to him, but defected to be with Asellus instead.
Heroic Sacrifice- In the Dark Labyrinth, in order to for anyone to leave, someone has to stay behind. White Rose decides that she deserves it as punishment for disobeying Orlogue, and stays so that Asellus and co. may leave.
Rival Turned Evil- To Dr. Okonogi. They went to college together, but Klein "became obsessed with strange and dangerous experiments for a secret organization [...] and was eventually expelled." Okonogi still considers him a friend, wishing only to stop Klein before he commits any more crimes..
What Happened to the Mouse?: It's unclear what happened to her after her second defeat by Asellus. In the Human and Half-mystic endings,she shows up on a scrapbook card with no context, although it's implied by the Full-Mystic ending that she and Orlouge's other princesses are killed.
Affably Evil-At first, he seems like a genuinely nice guy- In Emelia's quest, he gives her the Angel Broach, and in Lute's game, he gives him a ride out of Yorkland... he's also the head of Trinity, killed Lute's father, and plans to rule the world with a Humongous Mecha.
Evil Cannot Comprehend Good: Orlouge understands power and lust just fine. He doesn't understand that someone as powerful as Asellus might not want to be like him, conquering the universe and taking as many women as she can get her hands on.
Stalker with a Crush- For lack of a better trope, yes. As White Rose puts it, he never lets go of things he has acquired, ever.
Affably Evil: Though he's not a very nice person, he's one of the few mystics in Chateau Aguille who treats Asellus with any kind of respect.
The Chessmaster- Turns out, he's behind a plot to help Asellus overthrow Orlouge. Depending on how Mystical she is, he either gives her some Pluto Armor or fights to absorb her mystical power and be strong enough to fight Orlouge himself.
Luke, I Am Your Father- Although he may just be trying to mess with Red's head, during the battle at his base in Koorong, just before Alkaiser deals the final blow, he claims to have Dr. Okonogi's brain and asks Red/Alkaiser if he could kill his own father.
Rocket Punch- He shoots his hands off when he uses the move "Claw Bit". Once every turn they fly back around and attack a character.
Swiss Army Appendage- While his hands are detached, the rest of his arms can function as a rail gun, machine gun, or flamethrower.
Cool Chair- A golden bat and angel winged throne set atop a massive dragon!
No Celebrities Were Harmed- In Essence, he's also referred to as "Fireworks Lord". The artist based his face on her favorite Visual Kei band vocalist- Atsushi Sakurai. Sakurai's band is named "Buck Tick," which is pronounced "bakuchiku," which translates to "Firecracker."
Living Forever Is Awesome- Quite a few of the scientists remark on having a "disease-free, immortal body", either by offering you one or having one themselves. They don't even seem particularly bothered by the Body Horror that comes with it.
Slave Mooks- Berva's mooks in Shingrow are would-be tomb robbers who've been captured and forced to join.
The Caballero Family
The Mafia- Runs a protection racket in Junk, a factory in Scrap.
IRPOnote Inter-Regional Patrol Organization
Oddly Small Organization- The only patrol officers are Fuse, Ren, Doll, Silence, Cotton and Rabbit. In Essence Suzaku, Engineer Car, and ZEKE are deputized as well. Fuse also deputizes Red in one instance.
Space Police- Although whether the regions are planets or just places is... kind of ill-defined.
