The three new main characters in Force: Thoma Avenir, Lily-Strosek and Isis Egret. Due to accident, the three of them meet in Ruwella, with Thoma saving Lily in a science facility and Isis meeting them in a town. The trio are refuging from the TSAB because Thoma and Lily are framed as criminals, but they are captured by the Hückebein family and eventually rescued by Special Duty Section 6. As a condition to be protected by this section, they have to join in.Now being new recruits and being part of the Forwards, the three heroes train together with the five fellow Forwardsnote Ginga and Subaru Nakajima, Teana Lanster, Erio Mondial and Caro Ru Lushe under Captain Nanoha Takamachi and Vice-Captain Vita's supervision, and they assist their section to solve the Bible of the Silver Cross Incident.The recruit trio includes members of different "races". Thoma is an Eclipse Driver, Lily is a Reactor Plug, and Isis is a human mage.
Tropes common to the three:
The Apprentices: Like the other Forwards, they are the new students of Nanoha and Vita. They have also other mentors, e.g. Signum being Thoma's swordsman teacher and Reinforce Zwei being Lily's Fusion Dance teacher.
Badass Crew: The trio is already badass, but when they are in a team with their seniors, they are even a better crew.
BFG: Like the other Special Duty Section 6 combatants, they have Strike Cannons. Unfortunately, since they are BFG, Thoma cannot wield one with a single hand like Nanoha and Lily cannot even lift hers.
Custom Uniform: The three recruits wear light blue uniforms for some reason instead of wearing the marine blue Dimensional Navy uniforms like most other section members. Furthermore, their training outfit have white t-shirts in contrast to their five senpais and Vita with their dark blue t-shirts.
Power Trio: They are portrayed as the new main characters of the series, similar like the Forwards were in StrikerS, meaning that they always spend together as a trio. Not only they had a journey together before joining Special Duty Section 6, they are now living in the same room, despite two of them are girls and only one of them is a guy.
Senpai Kohai: They are the kohais of the other members of Special Duty Section 6. Their direct senpais are the other five Forward members.
Sixth Ranger: They join Special Duty Section 6 in chapter 17 and 18, and they are the three new Forward members.
Training from Hell: They have it harder than their five seniors, since the trio have to catch up very quickly so they won't pull down the others. Their first training session began with a very tiring 40 minutes long warm-up, and even Caro did it much better than them.
A boy who, while traveling in search of clues about the people who destroyed his home town, finds a girl named Lily in a research lab. He rescues her, gaining the powerful Divider-996 and becoming a fugitive from the TSAB in the process. Before these events, he is the Sole Survivor from the mysterious destruction of his entire town seven years ago. He later met Subaru Nakajima who helped him to find a new home, and he's nearly adopted by the Nakajima family, but he decided to travel around the world to find a hint to the destruction of his hometown, until the Bible of the Silver Cross Incident. Now being an Eclipse Driver, he is also the carrier of the Zero Gene and is now the target of the Hückebein family that tries to recruit him. Thoma joins together with Lily and Isis the Special Duty Section 6 of the TSAB that protects him from the criminals and trains him in combat.Thoma is currently the only known character with two Reactors: the Bible of the Silver Cross and his Reactor Plug Lily-Strosek.
A.I. Is a Crapshoot: The Bible Of The Silver Cross messed with Thoma's sight and hearing, hijacked his body and attacked anyone it considered a threat (which was pretty much anybody), and was close to ending the lives of numerous people in its several chapter-long rampage. All because it was its duty to protect its Driver. It'd be an understatement to say this was a faulty defense program.
All-Loving Hero: He is very friendly towards the Hückebein family and the Grendel family. The TSAB officers forbid him and Lily to make any contact with Hades because of his attitude.
Angst Nuke: The Divide Zero "Eclipse" gets fired like this the first time in the Hückebein's Warship when Thoma briefly flips out.
Beware the Nice Ones: After accidentally triggering Divide Zero "Eclipse" the first time and nearly killed two ships worth of people, Thoma threatened Fortis he would use it again unless they let his friends and the Special Duty Section 6 members incapacitated on board go.
Blood Knight: Averted, both among the cast and infectees. Thoma would rather avoid combat as much as possible if he can and only uses his Eclipse abilities to help. If his interactions with Signum were anything, he isn't one for sparring either.
Break the Cutie: A flashback in Chapter 5 showed he suffered one in the past that lasted from the destruction of his hometown all the way till his first meeting with Subaru. He noted that his meeting with her family was the first time he smiled since the destruction of his town.
Bungled Suicide: Attempted to end his life by jumping off the Hückebein's ship and fall to his death because he believed the Eclipse was too out of control and he'd rather be dead than turn into a mass-murdering killer. Unfortunately for him, the Bible of the Silver Cross took over mid-fall in response to Nanoha and a few people along with a few Hückebein started making a B-line towards him to intercept that.
Cloudcuckoolander: Seems to be overly-friendly to the point of best friends to the Hückebeins and doesn't seem to take the warnings given to him in stride. However, he hasn't actually demonstrated any actions that would back this up, such as letting the Hücks go or helping them in any way.
Contrasting Sequel Main Character: He is an opposite to Nanoha herself in many ways. While Nanoha is as female magical ace who is very sure of what she is doing and is clad in white with a slight enthusiasm for combat, Thoma is a normal male with a story-breaking anti-magic ability, dressed in black attire when reacted, and doesn't have the same desire for combat like most of the cast.
Cool Big Sis: Thoma seems to have complex of viewing many female characters, who are not related to him, as big sister figures. Those include the six Nakajima sisters who are ready to adopt him, Alto, Signum, and possibly Teana and even Caro. Hopefully not the Hückebein babes.
Crutch Character: Zigzagged. Thoma's main reason for being on the team is that the equipment isn't exactly perfected yet and have to resort to using someone like him given his powers are handy. He has only recently undergone some training, however, and hasn't really been able to demonstrate his abilities yet. He has been successful as part of a team, though.
The Ditz: Sorta. Most of it is due to not getting the hang of the military style the cast goes by. He comes across as someone who isn't probably cut out for military service, and yet he's been forced into it, so it ends up making him look like this.
Doomed Hometown: Two people destroyed his entire home, apparently killing everyone except him. He's looking for them.
Dull Eyes of Unhappiness: Chapter 5 showed he sported a pair of such eyes in the past. He had them all the time when he's going crazy in his Kurokishi Mode and fought everyone the Bible detected as a threat.
Hey, You!: The number of Eclipse infectees who don't refer to him as "Zero Boy" or variants can be counted on a single hand.
Hidden Depths: Earlier chapters showed he had rather deep resentments concerning the incident of the two murderers involved in the Vaizen Mines. In Chapter 4, he actually attacks Veyron first on the implications that he was one of the culprits in the event just by seeing the familiar blue wing marks.
Honor Before Reason: Noted by several characters that he feels a debt towards the Hückebein for receiving help from them despite the fact they're wanted criminals.
Horrible Judge of Character: Kinda bad in this regard about the Hückebein in general. Although this can be partially explained because he understands what the virus does to you, and thus he has empathy.
Isis later mocks him for it, saying it would be a bad idea to let him get close to Hades.
How Do I Shot Web?: Since Section 6 cannot exactly teach him how to use his Eclipse powers, he doesn't really know how to utilize his Story Breaker Power to the fullest effect. Most of the information on how to use them has been mostly through Hückebein members like Cypha and Fortis.
I Am a Monster: Has this opinion on himself when the Eclipse starts going out of control on the Hückebein's Warship and decided the best option was jumping off the ship to end his life. After Nanoha's stalling and Lily jumping in to help, he has since gotten better.
I Just Want to Be Normal: Implied, since he is more than happy to be one of the first few Eclipse infectees Shamal and the rest of the medical team can study if it means getting cured of his virus.
Ill Boy: When you consider he is technically infected with the still-incurable Eclipse, he is technically this to a degree. He also suffered some illness symptoms just after fighting Veyron for the first time too.
In-Series Nickname: The Bible of the Silver Cross is just shortened as Silver Cross ("Ginjuuji").
Informed Ability: During his fight with Nanoha, the latter notes that his fighting style is unlike anything she's seen before. The artwork of the chapter this is brought up in depicts him... slashing with his sword, hardly anything a veteran combat trainer would be surprised by in this setting.
It should be noted that the fight above was when he was under the Book's control, meaning it was essentially auto-pilot. This trope is stronger when he is in control of himself since he seems to be a terrible battler in spite of Nanoha's claims of his potential and the training received. However, Nanoha herself was once untrained, too, and yet had natural untapped talent, so he is following in her footsteps as a typical shounen hero.
Innocent Cohabitation: Shares a dorm room with Lily and Isis, sleeping in the same bed with the former. It's mostly platonic.
Kaleidoscope Eyes: In his Kurokishi Mode, he has different vision modes with different eye colors. Red Eyes, Take Warning fits where he can nearly see (or hear) anything clear except data, purple is Energy Mode which allows him to see more details and some data, and green is Normal Mode. Thoma's natural eye color is blue.
Life Drain: The Divide Zero "Eclipse" is implied to be this given some of the people being hit commented on feeling drained.
Like Brother and Sister: With Subaru. Chapter four confirms that she's the "Su-chan" he's previously described as being like an older sister to him, and was planning on making him part of her family.
Of course, he has this kind of relationship with the other Nakajima sisters.
Limit Break: Divide Zero 'Eclipse' in The Gears of Destiny, which deals 55% basic damage, that is the third strongest Full Drive Burst after Shamal and Precia's.
Literal-Minded: Not for him, but the Bible of the Silver Cross doesn't seem to understand figurative speech. At one point, he told the Bible of the Silver Cross to "pick a better atmosphere" when surprising him with messages. The book responds by literally analyzing the air for toxins.
Living Macguffin: The Hückebein desire him for his ability and potential to be a member, but Nanoha and company are making sure to prevent that.
The Load: For someone who has a highly coveted Story Breaker Power, he is practically the worst combat performer of the three, especially given Lily is starting to remember her duties as a Reactor Plug and take lessons from Reinforce Zwei while Isis has been profiting immensely from the training sessions.
Mage Killer: Thanks to the Eclipse. Since he is a good guy and almost all the bad guys in this story are Eclipse infectees, he is more of a Mage KillerKiller.
Meaningful Name: His Divider is numbered 996. Like the Dividers used by Cypha (944) and Veyron (928), each is named after a different model of Porsche. In Thoma's case, 996 refers to the 996-series Porsche 911, the first series of 911s to use water-cooled engines rather than air-cooled engines, just as Thoma is the first male main character in a possible heterosexual relationship within the entire series.
Mighty Glacier: In The Gears of Destiny, Thoma is a strong, but slow in close range combat. He's decent in middle range combat, but his moves are not made for long range combat. And his Limit Break is the third strongest in the game.
Morality Chain: Managed to talk Cypha into sparing Quinn, mainly because the Hückebein are still trying to leave a good impression with him.
My Hero Zero: He has the number associated with him due to the Zero Gene / Zero Effect.
Naïve Newcomer: With a rather unnerving emphasis on "naive" at times. Even Mariya refers to him as "naive boy".
Next Tier Power-Up: When Thoma reacted for the first time, his Reacted Mode had a red cape, his pants had free places, his waist cape was red on the inside, and he had one marking only on his face. He gained more marking on his body when he transformed a second time, and since his third time, his Combat Protective Clothing changed to the Kurokishi Mode ("Black Knight Mode"); it's more armored, the armor part on the left arm is completely different, the Divider-996 is much bigger and looks more dangerous and crazier, the pants are different, the red cape disappeared and the waist cape is black on the inside now, there are much more markings on Thoma's body, and the Bible of the Silver Cross in accompaning him. After Thoma gained the ability to control his Eclipse powers, he doesn't get red eyes anymore, but either green or purple.
Nice Guy: Arguably too nice. He gave a "Good luck" to both SignumandCypha before letting them battle, and the latter is one of the enemies who hacked apart the former (who happens to be his mentor) with a smile on her face. He doesn't seem to have an idea what kind of people the Hückebein are. Or perhaps he knows better than the rest of the cast.
Poisonous Person: Thanks to the Bible of the Silver Cross treating anything alive around him as a threat. In chapter ten, just him walking near Isis is enough to make her cough up a huge torrent of blood. Poor guy doesn't even want to fight anybody. Fortunately, Lily is able to suppress these effects.
There Is Only One Bed: There are two beds in their room, but he and Lily sleep in the same bed while Isis sleeps in the other bed.
Thou Shalt Not Kill: He is the only Eclipse infectee who has yet to truly kill someone and is trying to make an effort to keep it that way. In fact, he was willing to jump to his death out of belief it would assure he won't take any lives with the Eclipse getting out of control in his body.
Took a Level in Dumbass: He was a lot more aware of things around him and even held his own against Veyron at one point early in Force. Recently, he seems to either space out and make bad judgments or get nearly killed by people such as Kurt. To make it more clear, while he has been worse of a performer, his other two friends are going in the opposite direction to varying degrees. This could be explained that he is used to being on his own, and is having trouble incorporating in a military unit and assimilating military training. Any civilian would have issues in such a circumstance.
Unwitting Instigator of Doom: When one really thinks about it, Thoma's rescue of Lily ended up snowballing from a simple rescue to forcing the heroes to respond more quickly and hastily, triggered the Hückebein's response and the eventual meeting of both sides, and eventually causing a lot of damage in the long-run.
Useless Useful Zero Gene: The Zero Gene is essentially too dangerous to his friends and allies (and enemies) for him to actually use it.
Walking the Earth: Was doing this prior to the story beginning in the hopes of finding a sense of peace with himself.
What the Hell, Hero?: So far downplayed. His over-friendly behavior to other Eclipse infected, only ends up being scolded several times by Reinforce Zwei and Isis.
The Worf Effect: Outside of a few fights, he seems to be on the losing end in fights despite having the Zero Gene. It should be noted that the zero effect is essentially a WMD which will hit friend and foe alike, thus explaining why he hasn't used it yet.
Wrecked Weapon: His Divider-996 has been destroyed on several occasions, but seems to be able to repair itself.
The fourth Reactor Plug of the Strosek series, who was the subject of an experiment related to the Bible of the Silver Cross. Thoma rescues her from a research lab. Later after the first big battle with the Hückebein family, she, Thoma and Isis join the TSAB to assist in the Bible of the Silver Cross Incident. She's Thoma's Reactor Plug, and her main role is to suppress the Eclipse Virus within him and to support him in combat.
Tropes related to Lily:
All-Loving Hero: Similar to Thoma, she has no grudge against neither the Hückebein nor the Grendel and cares for them, especially the latter family. Also, she makes friends with the Raptors, who have a Hive Mind, but she gives them individual names.
Break the Cutie: Was forced to watch masses of people die in front of her in the lab she was contained to the point she became mute.
Bridal Carry: Often by Thoma; it's even on the cover of the first volume. Also by Fate when the Special Duty Section 6 rescued her and Isis from the Hückebein.
Captain Ersatz: To Reinforce Eins. Both are Artificial Humans who can fuse with someone and have books as their weapons. Like Reinforce's curse, Lily's virus killed many people in the past, and she could not do anything to prvent those, but both of them found a person (Hayate and Thoma, respectively), who saved them from their miseries. And her Engage Suit looks very similar to Reinforce's Knight Clothing. Additionally, Reinforce Zwei happens to be Lily's Big Sister Mentor.
The Chick: She's mainly the supporter of the trio. In battles, she's inside Thoma's body most of the time.
Cute Mute: Communicates entirely via telepathy. This makes her unable to communicate with Steed since he lacks the ability to receive telepathic signals. She eventually relearns to speak.
Deflector Shield: She can cast an own magic shield to protect herself and others.
Long Hair Is Feminine: She's definitely more feminine than Isis. However, since Isis never let her hair down (and we know how long Teana's hair is when she lets her Girlish Pigtails down), it's not known how much the difference of their hair lengths really is.
Poisonous Person: Before she met Thoma, The Virus inside her killed anyone who touched her almost immediately. Due to the scientists' desire to collect more data, that number was at least 70 people, probably a lot more. And they all died by mutating into blobs of flesh. No wonder she repressed those memories.
Took a Level in Badass: After being trained by Nanoha, Vita and Reinforce Zwei, she became much more useful in battle, unlike her Driver.
Trauma-Induced Amnesia: Lily's amnesia was due to the trauma of her life as a lab experiment, which caused her memory to deteriorate as she tried to escape her grim reality by retreating into the Happy Place of her mind.
True Blue Femininity: Her casual outfit has a blue skirt, blue boots and a blue ribbon in contrast to Isis's black and red outfit. And Lily is definitely more feminine than Isis.
A girl who sells clothes to Thoma and Lily, later helping them escape from the police and joining to their journey. She actually is the only daughter and youngest child of the Egret family, managers of Egret Security Services, a company which guards important people; her birth place is Rigate, a place on Mid-Childa. After the first battle with the Hückebein, she, Thoma and Lily join the TSAB to assist them in the Bible of the Silver Cross Incident. Isis' main role is that of a bodyguard to Thoma and Lily. Her Device is called Perfume Glove, or "Perfy" for short.
Tropes related to Isis:
A-Cup Angst: She hates being teased by her small chest size.
The Ace: Despite Thoma being an Eclipse Driver with the overpowered Zero Gene, Isis is the most competent fighter of the trio. This might be justified, as she was trained as a bodyguard, while Thoma had little training before the Bible of the Silver Cross Incident.
Animal Motif: Fitting to her name, most of her attacks are named after birds or are associated with them.
Badass Adorable: Surprisingly competent on the battlefield and looks adorable in her more happy moments.
Badass Normal: Not exactly normal, as she still uses magic, but only a little in contrast to most other mages. Isis has a crazy physical constitution, and uses an arsenal of real explosives made by chemicals, having a "not-exactly-magic-like" fighting style from the start.
Bodyguard Babe: To Thoma and Lily. Her family members are also bodyguards.
But Not Too Foreign: In-universe; she looks like that she's from Ruwella, the world where she met Thoma and Lily, but actually she's from Mid-Childa.
Cleavage Window: Her Armor Jacket, due to her vest and her Underboobs underwear. However, the window is very small, and she hasn't much cleavage either.
Cloudcuckoolander's Minder: She acts as this to Thoma in regards to the latter's bad habit of making the repeat mistake of being too friendly to other infectees. She reminds Thoma not to get close to Hades because he might end up convincing him.
Crazy-Prepared: Have pockets and a bag with various useful stuff as also a wide variety of perfume spells for various situations including one specifically designed to scramble the direction system of any guided projectile which proven to be very effective against ArnageofHückebein.
Crouching Moron, Hidden Badass: The cheerful and funny shopkeeper girl turns out to be an extraordinarily strong aerial mage who combines chemicals and magic to create flying bombs.
Damsel out of Distress: She's captured by the Hückebein, but once Arnage left her alone and the Hückebein had to fight Special Duty Section 6, Isis took the chance and freed herself.
Embarrassing Nickname: She does not like the Hückebeins referring to her as "Flatty" or "Washboard" every time they contact Thoma.
Hidden Depths: She seemed like a carefree Genki Girl traveller. However, there were hints that she's hiding something - she secretly worries about being deported by the TSAB, she can fly, she has an Armor Jacket and a pair of Devices, and can break steel manacles with her bare hands, not to mention still fight after getting her neck broken with an axe. But see Red Herring below.
Jumped at the Call: Quite willing to help Thoma after hearing that he's on the run from the TSAB. She later has second thoughts after considering what Hückebein and the TSAB would do to them, but decides that it's worth it to be with friends her age.
Made of Iron: Isis' reaction to having her neck (supposedly) broken by an Eclipse-powered axe? Shrug it off and get back into the fight a couple minutes later. Never mind that said axe blow was supposed to decapitate her...
Token Human: Is the only human among the trio, with Thoma being an Eclipse Driver and Lily being his Reactor Plug. She's also one of the only five human mages in Special Duty Section 6note Nanoha, Hayate, Teana and Caro. There are also the four other humans Shario, Alto, Lucino and Mariel..
Tomboyish Ponytail: She sports a short ponytail on the left side of her head, similar like Nanoha. This is a small contrast to Lily who wears her hair straight, as Isis is more of an Action Girl than her.
Took a Level in Badass: She was a very capable fighter as she was, but she has been improving her skills on the battlefield thanks to the training provided by Nanoha, Vita, and Signum. The Grendel incident has shown this, where she was practically able to stop Mariya on her own while Thoma's performance was rather forgettable to say the least.
True Companions: Despite knowing Thoma and Lily only for a short period of time, she sees them as her important friends and tries to help them, no matter what.
Underboobs: Not her vest, but the underwear of her Armor Jacket.
You Monster!: She doesn't adress her directly, but Isis calls Nanoha a demon instructor. She is rather grateful for the training though.
The Hückebein Family
The antagonists of Force. A group of infamous killers that are known for slaughtering whole settlements, leaving no one alive. They are not actually related, but are all infected with the Eclipse virus. Widely believed to be invincible, they are now after Thoma in the hope that he will join their family.
Tropes common to the Hückebein:
Animal Motif: Very minor, but their family name can mean "evil bird" (as evident when Quinn was referring to Cypha as "fowl" in Chapter 23) and they share the same wing-like marking on their bodies. They don't really show anything of this trope past this, though.
Anti-Magic: They take this Up to Eleven, especially in Reacted Mode, where conventional Devices shatter upon contact with their bodies.
Card-Carrying Villain: The Hückebein don't hide that they're criminals and openly admits their crimes. This is a huge contrast to Hades Vandein, who pretends to be an innocent civilian despite being Obviously Evil.
Cool Starship: The Esquad, which is implied to be an over-sized Divider.
Their tendency to No Sell everything has made this power somewhat redundant, however. It's only actually been used twice so far.
As of Chapter 29, Special Duty Section Six now has a mean to nullify this to a degree with bullets that inject antibiotics.
Hey, You!: To drive in how arrogant they are, they almost never call any of the cast by their actual names (aside from Thoma). They usually call Isis "Flatty/Washboard" for amusement and any of the Section 6 members "Public Servant" as a derogatory name.
No Sell: Almost EVERYTHING! If Chapter 19 and 23 are anything, even other infectees don't fair any better, unless that infectee is Thoma possessed by the Bible of the Silver Cross or Hades Vandein.
Not So Invincible After All: As of later chapters, this trope has been slowly creeping in since Cypha's defeat in Chapter 24. In Chapter 29, Teana has shown their chances at studying the Eclipse by nullifying their Healing Factor with bullets filled with antibiotics. Compounding with the improvements done to the Anti-EC equipment, Section Six are now capable of doing reliable damage to infectees. Even Veyron acknowledges that they no longer have a one-sided advantage anymore.
Power High: They enjoy their Eclipse powers a bit too much.
Power Tattoo: Every one of them has the same kind of markings, implying to be the result of the Eclipse.
Sigil Spam: All of them do share one marking pattern: A stylized design of a wing.
Arnage and Veyron attack the two other Eclipse-infected because the Hückebein don't attack innocents willy-nilly and their doing so brings unnecessary attention on the Hücks, who are convenient to misblame.
This also extends to their behavior around Thoma. They make the effort to avoid harming the people he loves to avoid causing disfavor with someone they want to join them. Arnage is the only one who seems sincere on her feelings with wanting him to join though.
Psychopathic Manchildren: Although one of them is an actual kid. They don't seem to give much concern about anything unless it is them and indulge in rather hedonistic activities when they aren't doing an errand or job.
Shameful Strip: When the Hückebein capture Thoma's group, they proceed to strip them of all the equipment they can remove. Unsurprisingly, while Thoma is able to keep the Instant Armor that comes with his Kurokishi Mode, Lily and Isis are left completely naked while their enemies interrogate them. However, the Hückebein have enough dignity to cover the girls with towels and let them being interrogated by Arnage and Cypha, while Thoma is interrogated by Fortis and DeVille.
Spell My Name with an S: Most fans don't have an Ü on their keyboard, that's why they incorrectly spell the Hückebein as "Huckebein" which is wrong. To avoid this problem, "Hueckebein" should be fine (Ü=Ue). This is also the fault of the fan translators that's why most fans are sticking with the incorrect spellingnote Not the group "Girls in Boxes" who did it right.
Too Powerful to Live: Type 1 - They are overpowered as hell and are easily the most dangerous characters around, but they didn't disappear quickly and as a consequence they're dominating the story for now.
Unskilled, but Strong: With the exception of Veyron (who can't react) and a few others, a large majority of the Hückebein are very over-reliant on the powers of the Eclipse virus and their Dividers. The only thing mitigating this is how broken their power is.
Woobie, Destroyer of Worlds: They seem to become this. Sure, they have to try to find a way so they could control their Eclipse disease. But their unsympathetic actions, like slaughtering villages and communities, massacring the innocent people who had nothing to do with their affair is not a justifications for their reason to survive. Emphasize more on "Destroyer of Worlds" rather than "Woobie", due their personality.
You Can't Fight Fate: Their general reaction to Section 6 trying to save Thoma and finding a cure to the Eclipse in general is mostly this.
The leader and founder of the Hückebein family. She gathers several Eclipse infectees to her family and she wants to adopt Thoma, too. Curren is one of the first generation of the Eclipse infectees.
Tropes related to Curren:
Badass: As smug as she is, one can't deny that she demonstrated the legitimacy of her badass credentials by one-shotting three of the most powerful current characters with a normal sword and not even bothering to activate her Eclipse powers.
Badass Adorable: She makes cute faces very often. Her Teenage Mode is even more adorable, and it lacks her evil expressions.
Berserk Button: She does not take kindly whenever her family is deceived or screwed over in anyway. She also was less than pleased when Hades suggested her selling out Thoma to him for informaiton on the Seed Of Origin.
Big Bad: The official leader of the Hückebein Family.
Big Damn Heroes: Inverted in the villain-saving-villain sense. When Hayate is casting the Heimdall spell to bring an iceberg on the Hückebein ship, it looks like Cypha can't carve it up in time until Curren shanks the former, causing the iceberg to break.
Bitch in Sheep's Clothing: Her laid-back and child-like behavior has a habit of giving way to her ruthless and more unhinged side rather often.
Cat Smile: Sports something similar to this in Chapter 13 after stabbing Hayate.
Combat Pragmatist: If her behavior in Chapter 13 and 29 are anything to go by, Curren is not the type to play fair and screw around with her opponents too much.
Curb-Stomp Battle: Defeats Vita and Erio with ease despite both being armed with Strike Cannons, she even managed to destroy both AEC weapons with a sword that wasn't even a Divider.
Come Chapter 28 and she ends up on the receiving end along with Veyron thanks to Hades.
Cloudcuckoolander: A villainous example, and not meant to be endearing. To add some perspective, fellow Hückebeins Cypha, Fortis and Arnage are more closer to reality than she is. For example, she mentioned she has finally made her debut in Chapter 13 with a pseudo Cat Smile and acted like the battle was a stage. In another, when she is contacting Thoma via his book, she is multi-tasking and nonchalantly discussing a meeting even though Section Six might be listening in. Finally, if Vandein's lines are anything, she doesn't seem to take the infection as seriously as most.
Deadpan Snarker: When she is really condescending, she tends to indulge in belittling in her foes.
Disproportionate Retribution: After realizing that she and other fellow Hückebeins become scapegoats by Vandein, she retaliates by demolishing the Fourth Factory and sending her family after Vandein's agents.
Faux Affably Evil: The silly mannerisms and the laid back way she acts to Thoma hides the fact she is just as vicious and ruthless as the rest of the Hückebein. Lampshaded by Reinforce Zwei when she warns Thoma to not forget she is acting like that to appeal to him.
Foil: Arguably, to Hayate. Both are revered among their peers and are their leaders, own powerful books, and possess great ability to lead. As for differences, Hayate is one of the strongest mages who sucks in melee and was highly mature even as a child, while Curren is one of the strongest Eclipse infectees, a monster in close combat and is downright immature even as an adult. Or as teenager.
She also is a foil to Thoma and Lily. Like them, she has stronger-than-normal Eclipse power, a book user, and has a slightly childish outlook on life. Unlike them, she knows how to utilize her powers fully.
In an odd way, she is also one to Vivio. She also has the ability change her body age, but unlike Vivio, she is lacking in maturity and is a Jerkass while Vivio is Wise Beyond Their Years and is a Nice Girl. Their transformation magic work in opposite ways: Vivio transforms to become physically older, while Curren transforms to become physically younger. Also, while Vivio is a protagonist of her own series, Curren is an antagonist (or Villain Protagonist, depending how you look it) of this one.
She, like Isis, knows well enough that it would be a bad idea if Thoma was to ever get in contact with Hades Vandein. Although it was less poor choice of judgment and more of concern Hades would get his hands on the Zero Gene and replicate it.
Giggling Villain: Typically, characters who speak with musical notes use it in a somewhat endearing manner. Curren does not.
Green Thumb: A lot of her book's powers involves plants.
Hey, You!: Actually averted in chapter 29, where she asks for and calls Fate by her last name. This is after Fate and Erio land a combo attack on her, so it could mean she's willing to show some respect now.
Hope Bringer: To the rest of the Hückebein family. Demonstrated when she appeared and stabbed Hayate In the Back dispelling the HEIMDALL spell which had been putting the Hücks on a tight spot, upon seeing her all the Hückebein rejoiced which was followed by Curren's speech. Say what you want about the woman and her horrible crimes and smugeness but you must admit she's a born leader with a great charisma.
Katanas Are Just Better: Played with. Her sword breaks after destroying Vita's and Erio's Strike Cannons, yes. But she was also using a completely mundane weapon with no magical ability at all when she destroyed them.
Benevolent Boss: Moodiness aside, she is rather respectful to her own family members and wasn't keen on selling Thoma over to Hades, even using her abilities to assure their safety while fighting with them.
Wounded Gazelle Gambit: Although she's not injured badly, she's pulling this by suggesting Fate and other Section 6 members to arrest Hades, then she's reverts to her teenage form and retreat alongside with her fellow Hückebein.
Younger Alter Ego: Just like Vivio, Einhart, Rio and Fabia in ViVid, she can change her age whatever she wants. As seen in Chapter 29, she has a Teenage Mode which is rarely or never seen even among the Hückebein members.
Veyron of Hückebein
The first introduced antagonist, who was seeking Lily and Thoma's Divider. Veyron is the only member of the Hückebein without a personal Reactor. He's one of the first generation of Eclipse infectees. The Divider-928 is his favorite weapon.
Badass: He is one of the few Hückebein who have shown legitimate credentials of this trope by virtue of his fighting skills and inability to fall on an ability to react. Fortis even mentioned the idea of getting him a better Divider in order to react, but Veyron's response was that he was good enough as he is. Curren even has high regards for him as a competent battler.
But for Me, It Was Tuesday: In earlier chapters, it was heavily implied that he was one of the two who attacked the Vaizen Mines that caused Thoma years of hell before running into Subaru, but he doesn't seem to recall the details or even care for that matter.
Dark and Troubled Past: Implied. In chapter 19, a brief shot of his memories shows a long-haired, ill-looking girl with the same hair color and the same two Idiot Hairs as him.
The Dragon: Curren seems to have special attention to him more than the others in their group, implying he may be this in spite of lacking an ability to React.
Establishing Character Moment: Thoma and co. first encounter him in a Church full of slain nuns. Not only this establishes him as a nonchalant killer, but does it to the Hückebein and most Eclipse infectees as a whole.
Face Palm of Doom: Gets this done to him by Diego, but it doesn't take. Returns the favour more permanently shortly afterwards.
Honor Before Reason / Too Dumb to Live: Tries to insist he can fight well despite being unable to react, even though it is clear there are times where he cannot catch up to the others well. Even with Rosalia there to prevent the Eclipse Dominant from keeping him bedridden, he doesn't want her as his Reactor Plug out of belief he will get weaken (when it means being able to React) and is annoyed Curren is willing to freeze him for the safety of the group.
Huge Guy, Tiny Girl: The huge guy to Rosalia who is very small. Veyron is almost as tall as DeVille.
Only Sane Man: While his mind isn't any more intact than Cypha or Arnage, he seems to be the only one in general to be aware of Thoma's general uselessness and doesn't think he is worth recruiting due to being a liability more than anything. Even though others insist, Veyron's point is still correct.
Power Fist: Along with his Divider, he uses this to make up for being unable to react.
Weak, but Skilled: He can't React, but that hasn't stopped him from holding his own against RF 6 or defeating a Reacted enemy Eclipse infectee in direct combat.
Not-So-Harmless Villain: He's only weaker in comparison with his fellow Hückebeins. He still has very high endurance(as shown when he withstood a direct shot from a Strike Cannon and continued to fight despite bleeding) and his Claw Grab equipment has easily put him on par with other Reacted EC-Drivers. He has also showed himself to be even stronger than Subaru. Coupled with his Determinator qualities and cool head, he is quite the dangerous opponent.
Overshadowed by Awesome: The Reacted EC-Drivers he had fought on-screen were implied to have had an infection that wasn't the real thing. When he fights an infectee who won on the higher tier of the lottery, such as Vandein, he ends up getting thrashed.
Worthy Opponent: He was surprised at how well Thoma was holding up in their initial fight, even impressed at how he got some damage and was disappointed to run out of ammo.
Cypha of Hückebein
One of the main combatants of the Hückebein. She becomes Signum's rival since their first battle. She owns the Divider-944 and the Reactor König-09.
Tropes related to Cypha:
The Ace: She likes to describe herself as this. How true that is, however, is yet to be confirmed.
Blood Knight: Her previous stoicism is replaced by bloodthirsty enthusiasm once Signum starts putting up a good fight. And, as the following events show, she will do anything to win.
Boobs of Steel: Just beats out Reinforce for the largest bust in the series, and is the most physically-oriented fighter of the female Huckebein.
But for Me, It Was Tuesday: It took her a few minutes to remember exactly which colony Signum was accusing her of slaughtering, in spite of the fact that she personally murdered every single one of the nearly eighty inhabitants.
Curb-Stomp Battle: Against Quinn Garland of the Grendel Family. Cypha overpowers her at first, then Quinn reveals she was only using the basic form of her Divider and promptly reacts. Cypha quickly trashes her anyway.
Evil Gloating: To Signum, about slaughtering a world's entire population.
Evil Mentor: Tries to play as one to Thoma whenever she meets up with him. In Chapter 23, she shows him a few basic tricks provided by the Eclipse virus to become a better fighter. This is probably because she wants him skilled enough by the time he is in their family.
Mood-Swinger: She can be either stoic or psychotic, depending on the situation.
Not So Stoic: She's a very serious woman in contrast to Curren and Arnage, but Cypha has a very sadistic personality and shows it in combat.
Oh Crap: She... underestimated Signum, to put it lightly.
Paper Tiger: An understated example. Despite having a threatening appearance and personality, so far Cypha has gotten smacked around by Signum with a handicap (admittedly before reacting), not proven to be a great challenge for Fate without one, knocked unconscious by Thoma with Divider Zero "Eclipse", failed to impede Heimdall when it was about to destroy the Esquad, and now been defeated and forced to flee by Signum, with an arguably worse handicap this time.
Smug Snake: Several examples since her introduction but special mention goes to Ch. 24. When Signum finally returns with an AEC-Equipement and challenge Cypha to a re-match, Cypha's reaction was to fight Signum with a Divider taken from an enemy she just trashed shortly before (see Curb-Stomp Battle above for details) instead of using her own, furtherly mocking Signum's low-level threat to her eye. And that utterly bit her back in the ass.
Token Wholesome: Unlike the other two adult female Eclipse Drvers of the Hückebein, Cypha's normal outfit is a fully-covering bodysuit. But Pure Is Not Good, and despite her conservative clothing she's the most outwardly vicious of the lot.
Underestimating Badassery: While she does have the Eclipse virus giving her a bit of help, Cypha really should not be underestimating Signum.
Villainous Breakdown: She was keeping calm in her rematch with Signum until the former surprised her with a few alloy needles from her shield. After that, her combat performance went downhill.
BFGs: Biggest example of this in Nanoha, which is really saying something.
Big Eater: Implied to be one of the reasons the Hückebein restore their food stocks rather frequently.
Blood Knight: Unlike Cypha, she sees the notion of fighting Special Duty Section Six with pure enthusiasm rather than immense sadism.
Boisterous Bruiser: Villainous example. She is brash, loud, and energetic compared to most of the group. She also emphasizes the 'bruiser' with sheer firepower.
The Brute: Put bluntly, Arnage is not one for strategy or subtlety. First of all, she'd rather just blast down anything with the sheer power of her Reacted Divider. Second, it didn't take long for Arnage to get frustrated in her skirmish with Isis precisely because her typical tactics of resorting to overwhelming firepower does not work.
Crippling Overspecialization: Until DeVille interfered, Arnage was practically unable to do anything to Isis. Needless to say, Isis practically made her look like an idiot.
Cool Big Sis: Her introductory scene has her hanging out with Stella and she seems to act laid back around most of her group when she isn't being batshit insane. She was also very open to the idea of adopting Rosalia into the group while Veyron was aloof. In addition, her comments to Thoma were that she wants to help him out, meaning she legitimately cares for him.
Cowgirl: Dones this kind of dress with a cowboy hat included in her appearance in Chapter 18 and 19. She drops this outfit by her next appearance though.
Dark Action Girl: A lighter example in comparison to Cypha and Curren due to Arnage rather funny character. Nevertheless, she has the same Eclipse powers as the other Hückebein.
The Nicknamer: Mostly towards Isis in regards to her cup-size. A number of the Hückebein adopt those names when referring to her when talking to Thoma.
Oh Crap: Freaks out when seeing Thoma's Hundred Million attack. And she also underestimated Isis "Flatty" Egret and her chemicals.
Perky Female Minion: Her character is not as dark as the others, but she has a cheerful personality and is actually the funniest of them.
Person of Mass Destruction: Fortis does not want her to engage in combat inside the Esquad. After seeing her react, it was clear she would have probably caused a lot of damage to the ship by accident due to her personality. Needless to say, she likely has the most offense potential of the Hückebein.
The Rival: Not shown as such, but she gives off this vibe towards Isis like how Cypha is to Signum and how Veyron was to Thoma.
Superpower Lottery: She is the only known Eclipse infectee so far with two different Reacted Modes.
Trigger Happy: She opted to do the trope mentioned above as a solution towards the "Hundred Million" attack instead of fleeing, and it worked. In addition, her main approach is essentially "react and shoot first".
Violent Glaswegian: It sounds like she is from the fantasy equivalent of Scotland/Ireland given she says things with an accent ('ey, 'ell, etc), has the red hair associated, and has a bit of a temper to match.
Evil Genius: Mentioned to be the brains of the group in his Force Analyzer profile.
Informed Ability: The only things he's done so far in the story are exposit information and stand in the bridge doing absolutely nothing in the middle of an attack. It seems like this intelligence doesn't extend to actual fighting, ironically. Then there was the fact he was doing the opposite of winning Thoma over by discussing unsavory things like murder.
It Gets Easier: His attitude on killing, which is necessary for him to survive. Thoma does not seem to agree.
The Medic: Acts as the doctor for the Hückebeins, as show in Chapter 30. However, it's mentioned that medicine is not his speciality.
Mission Control: He was directing the rest of his family and providing information away from everyone else during one of their raids on one of Vandein's factories. He was also spending most of his time with Stella on the Esquad when Section 6 was chasing them.
Mr. Exposition: He was this in-universe for Thoma by being the first person to explain some of the details of how the nature of the virus works for him. He never got around to explaining details on the "zero effect".
Non-Action Guy: We have yet to see him do anything outside of being Mission Control while the other male Hückebeins have displayed their abilities.
He also underestimated Thoma's mental condition and felt it was safe to simply tie him up. Cue to getting hit with the Divide Zero "Eclipse" and being threatened by Thoma with another blast if he didn't let Special Duty Section 6 and his friends go.
A few chapters later, he is watching Nanoha battle Thoma with the Fortress and remarks that he isn't impressed with their Anti-EC equipment. He likely has a different opinion now that Cypha got her ass handed to her by Signum and Curren got skewered by Fate and Erio.
Cute Mute: She typically communicates solely through facial expressions and pantomime that the other Hückebeins translate into complete sentences... somehow. She becomes capable of speech only after merging with the Hückebein's ship.
She later speaks even without Reacting, though.
Cute and Psycho: Imagine someone like Vivio infected with the Eclipse virus.
Glowing Eyes of Doom: The Force true colored manga shows that her eyes glow all the time when she's piloting the Esquad Hückebein.
Moral Myopia: Refers to the TSAB Forces intruding on their ship as "bugs" and argues that the TSAB shouldn't be coming after them for their killings since they do them on non-administrated worlds. Could be justified due to her young age.
Spaceship Girl: She seems to have the power to control the Hückebein Family's spaceship fortress by merging her consciousness with it. She can even enhance the ship's powers and repair damage it's taken.
The Hückebein "Fortune Teller" who meets up with Cypha in Chapter 25 . She is their irreplacable informant and interrogator.
Tropes related to Sonica:
Berserk Button: Isn't fond of doing things for free, especially if they were nothing.
Brilliant, but Lazy: According to Fortis, if she wanted to bother, she can get all information out of her targets. Of course, she doesn't want to do it.
Bunny-Ears Lawyer: Chapter 26 reveals she has an amazing talent at extracting information/"data" off the people she touches and is essentially a downright irreplacable informant or interrogator. Unfortunately, Fortis notes she beats to her own drum, is never on time, and charges her clients an exorbitant fee, even with a discount. Sonica notes the 800K cost isn't so bad considering those will pay for her services tenfold.
Chained by Fashion: Downplayed. She wears some chains around her hip with her belt and at the shoes, but that seems to be in.
Cry Cute: When Veyron is lying in her arms without his heart.
Deadpan Snarker: Gives off this vibe in regards to the people she is working with, with the first time towards Cypha in regards to getting thrashed and nearly captured due to pride.
The Smart Girl: Is actually better than Fortis at this because of her ability to extract information.
The Team Normal: In Chapter 28, when she along with Curren and Veyron got trapped in binds, the latter two instantly broke out while she was still tied up. This would hinting at the Fortune Teller being possibly the only non-infected member and can explain why there is no visible markings on Sonica at all and staying close to Curren. It then gets further emphasis on Chapter 29 where Curren and Veyron are focused on keeping her safe since they know she cannot take a hit. And Chapter 30 reveals that she's not very familiar with the Hückebeins' extreme regeneration abilities; she knew they can regenerate their limbs, but when Veyron loses his heart, she freaks out in that situation.
The former Reactor Plug of the infectee Diego until he's killed by Veyron. She's taken by Veyron and Arnage to the Hückebein family, and it seems she's about to become Veyron's Reactor. Rosalia is the 5th Strosek of the Strosek series.
Tropes associated with Rosalia:
Anti-Villain: She's actually a neutral character who just happens to be on the side of the villains.
Peek-a-Bangs: A rare occassion, though the eye that was shown was closed.
When we finally see her eyes open, both eyes are shown to have a rose in them.
Break the Cutie: Diego's was a really abusive Driver to her. And think about that she's a Strosek like Lily and what kind of experiments Lily had to suffer.
Dark and Troubled Past: The only thing we know is a flashback and the fact her former Driver was a colossal, abusive asshole. Then there is the implications she might have been experimented on as well.
Does Not Like Shoes: Though, it's more like a lack of normal clothes, as Diego doesn't give a crap for her unlike Thoma to Lily, and the Hückebein haven't give her proper clothes, yet.
Fusion Dance: With Diego. It's possible she will be able to properly react with Veyron, too.
Huge Guy, Tiny Girl: The tiny girl to Veyron. Even though Rosalia's biological age is 14 years and seven months, she's very small compared to the other females.
Neutral Counterpart: To Lily. Both have similar backstories, but Rosalia had a really big Jerkass as her Driver unlike Lily. Now that Rosalia is now adopted to the Hückebein family, she supports Veyron in similar way like Lily does to Thoma.
Shrinking Violet: Possibly due to all the abusive treatment she got from Diego. And/or from the experiments.
Eviler than Thou: While Curren has shown some somewhat humanizing traits (at least only towards her family members), Hades Vandein has shown nothing but a heavy air of evil since his appearance. He has such a massive Killing Intent that the cast in the area see hallucinations of it. It's hard to say if it was illusion powers or if he is that evil.
Fake Kill Scare: Chapter 26 shows the Special Duty Section 6 about to arrest Hades but we see Teana hacked apart immediately by him. Next panel shows she is alright and that everyone in area saw the same hallucination.
Faux Affably Evil: For a man who has a charismatic smile and having a well-meaning goal, there is a heavy air of evil around him.
No Sell: The first person to pull this on Curren and Veyron by shrugging off their abilities easily. That says a lot. It turns out that thanks to being directly infected by the Seed of Origin, he has the Eclipse Dominant which lets him shut down other infectees. Yikes.
Obviously Evil: So much that it isn't even funny. The other characters don't buy his "innocence" anyway, but he still pretends to be one and tells unbelievable lies. He claims fighting the Hückebeins with his Divider as justified self-defense, and after he rips off Veyron's heart, he justs tells the TSAB, a careless criminal just droped it... Yeah, they don't buy it.
Plaguemaster: Most of the Hückebein personally believe he has had a hand in initiating the Eclipse outbreaks. Whether or not this theory is true has yet to be confirmed.
Mostly confirmed in Chapter 28 where he knows of the source, the Seed Of Origin, and likely has that power.
Story Breaker Power: Not only his powers relate to the Seed Of Origin, but he curb-stomped Curren and Veyron.
Chapter 30 adds a spotlight to put more focus. Specifically, he was infected by the Seed of Origin directly and has the ability of Eclipse Dominant, which lets him screw over any other infectees that lack a Strosek Reactor Plug. He can basically cripple any of the Hückebein.
Superpower Lottery: Possibly more broken than Thoma's Zero Gene given the Seed Of Origin is the source of the Eclipse virus and allowed him to fight evenly with Curren and Veyron without trying. Chapter 30 goes further because by being directly infected by the Seed of Origin, he has a massive edge over most other infectees thanks to Eclipse Dominant.
Villain Takes an Interest: Just like many members of the cast, he is attracted to Thoma for his potential due to the Zero Gene. In addition, he is also interested in anyone with unique abilities, such as Sonica's Mind Probe abilities and Curren.
Villain with Good Publicity: Until the cast was able to get a confession out the Grendels (who had explosives set in their brains), they were having extreme difficulty getting a warrant for his arrest.
Well-Intentioned Extremist: He is conducting illegal experiments of the Eclipse virus by infecting people and sending them out onto low-key worlds because he is seeking to find an alternate source of energy from utilizing it.
The Grendel Family
Another set of Eclipse infectees. They were hired by Hades Vandein to steal the Raptors from Special Duty Section 6, but they ended up arrested by them. The four members are Kurt Grendel, Mariya Ranevskaya, Quinn Garland and Lolo Endive.
Butt Monkeys: As time goes on, it has been shown that these children did not win the Superpower Lottery. It really says something when they have a virus brimmed with most of the series' Nightmare Fuel and yet are not treated even remotely seriously.
When they get shot down by Nanoha in Chapter 27 in their failed escape attempt, she addresses the four as if they were misbehaving children more than high-security prisoners.
Crouching Moron, Hidden Badass: They might come off as disorganized teenagers, but Thoma learns the hard way not to underestimate them when Kurt shatters the blade of his Divider with ease as well as nearly strangling the boy.
Defeat Means Friendship: Subverted. Section Six shut them down, Thoma looked like he was becoming friends with Kurt, and they seem to not mind their new conditions. Then comes their next appearances, and the four are trying to escape their prison. However, the officer who stops them from their escape and shoots them down is Nanoha...
Diminishing Villain Threat: They went from somewhat intimidating and dangerous to being used for humor so far. And they're infected with a virus in a series that is the darkest in the Nanoha franchise to date.
Explosive Leash: Oddly enough, Kurt was actually aware of the fact they were installed with explosives in their brains unlike Marty.
Improbable Weapon User: Mariya uses bullets without using a gun. Lolo also gets a mention for using tasers, but both are justified for presumably being their Dividers.
Ineffectual Sympathetic Villain: While they are still dangerous opponents, they are nowhere near as effective as the Hückebein in skill and power. As time goes on, the ineffectual part plays more and more.
Jerkass: As expected of Eclipse infectees, but it is noted they aren't as severe as the Hückebein.
Benevolent Boss: Kurt was willing to die in the middle of an interrogation from an implanted explosive if it would mean his friends would come out free and unharmed. That makes him one of the more noble people infected with the Eclipse.
Smarter Than You Look: For someone whose nickname is "dumbass" among his friends, Kurt has a habit of displaying his leadership skills among the Grendel and is much more competent than Thoma.
Space Master:Kurt can warp his posessions, and his friends' too if they are touching him, without any effort. On the downside, he could can only retrieve items considered "his" or his friends if they are in contact with him. The range seems to be wide given Kurt was able to take back Quinn's Divider, which was stolen by the Hückebein.
One of the requirements for his ability is for the item he wants to retrieve to be in the same dimension as he is. Thus the only way to keep Kurt from getting back "his" possessions is to place them in another dimension.
Take Over the City: Kurt's original plan, which surprised Thoma at how small-scaled it was.
Super Strength: Kurt nearly strangled Thoma to death after effortlessly destroying his Divider, but Erio and Caro could save him.
White Hair, Black Heart: Subverted. He has silver hair but it quickly turns out that Kurt is not an extremeJerkass like a large majority of other infectees and has some humanizing traits. He is still has issues due to the virus, but he is merely a gangster at best when it comes to being evil.
The sniper of the Grendel family and Kurt's right hand.
Good Thing You Can Heal/Gory Discretion Shot: In order to apprehend Mariya, Isis has to "destroy her lower extremities". In other words, she uses one of her perfumes to dissolve/burn away everything from her hips down. We are only shown the perfume creeping up on Mariya, Perfy reporting success, and a much later shot where Mariya's legs appear normal but her socks and boots are gone.
Hair-Trigger Temper: She is easily becomes angry. It does not help she is the sanest one in the group.
Hypercompetent Sidekick: All three of the girls are more competent than Kurt, but Mariya stands out. Due to being (mostly) sane compared to the others, she caused the most damage of the four by sniping Thoma and the Raptors into submission without any effort. Kurt is aware of this and actually intended for her to take over in the event of his death because of it.
