Blackjack, aka. 'The Security Mare' (Given name: Go Fish)
The main protagonist of Project Horizons, Blackjack is a security pony in Stable 99 where Free-Love Future rules and the stallions are used as breeding tools. Upon discovering the EC-1101 in the Stable's systems, Blackjack flees out into the Wasteland to uncover its secrets, facing the horrors of Hoofington. Becoming known as the Security Mare, Blackjack considers herself Book Dumb, will charge into a situation recklessly, and believes she is at her best when drunk. Her greatest strength and weakness is her Chronic Hero Syndrome, and she wishes to help everyone in the Hoof, or die trying.
Action Bomb: Following an encounter with Killing Joke. Not as awesome as you'd think, since it only goes off when it's "funny."
Something of a subversion, since Blackjack herself doesn't explode. Anything she touches (the ground, a ruined vehicle, an elevator car, Rampage) explodes instead.
Back from the Dead: Following the total failure of her heart and respiratory system, Blackjack is clinically dead for several hours. Her brain and body only survive because Rampage is used as a willing life-support machine until BJ can be implanted with synthetic organs.
Handicapped Badass: From Chapter 27 onwards, eventually escalating to an insane degree. As of Chapter 33, she's missing both eyes and all four legs, and still manages to kill one of her attackers while nailed to the floor.
Came Back Strong: Temporarily lost use of her magic, but gained an augmented cybernetic body.
Casual Kink: Blackjack has masochistic tendencies, though it's unclear whether she always had them or if they developed subconsciously from her early guilt and desire to be punished. She gradually becomes more open about them, both with herself and her friends, and enjoys having Glory rough her up in bed.
Chronic Hero Syndrome: Blackjack is a life-long sufferer, with an unfortunate tendency to act without considering the consequences. A likely candidate for BJ's Fatal Flaw. She's so focused on helping others that she ends up saddled with crippling guilt when things inevitably go wrong, to the point of almost completely disregarding her own health. She becomes overwhelmed with guilt whenever she is forced to harm noncombatants herself, and normally can't bring herself to kill in cold blood.
Cosmic Plaything: Blackjack has good intentions, but things rarely turn out as she hopes and her attempts to help often make things worse. This trope may be literal, if Big Daddy and/or the zebras are to be believed.
Extreme Omnivore: The lesser variety. Blackjack's bizarre sense of taste says that the rancid-orange-juice flavor of Rad-Away is "tangy" and a raw-egg-and-chili-powder hangover cure is "not bad". Said hangover cure made Rampage vomit. She happily eats Glory's cooking. After upgrades, she adds metal and rocks to her diet and becomes the greater variety of Extreme Omnivore.
From Nobody to Nightmare: Blackjack starts out as the most incompetent security mare in Stable 99. Within weeks of leaving, she accumulates a kill count in the hundreds, including innocents and children.
Good Scars, Evil Scars/Beauty Is Never Tarnished: Averted. Blackjack becomes increasingly disfigured over time, accumulating significant laser scars and partly-healed bullet wounds on her face and torso, along with a large 'Y' shaped scar over her missing eye. Eventually, her taint contamination starts to manifest in the form of hideous tumors and does awful, unseen things to her legs.
Played Straight and Justified, at least in the long term, once she becomes a cyberpony - her healing talisman regenerates superficial wounds, so long as she's mostly intact.
Hallucinations: What she believes Dealer to be, but also sees others while in strong magical fields or suffering from sleep deprivation.
Healing Factor: Inbuilt healing and repair talismans grant her this following her augmentation, but she needs to fuel the repairs by eating raw materials.
Hero with an F in Good: She means well, but Blackjack's attempts at heroism or redemption generally wind up resulting in massacres, dead foals, permanent physical or psychological damage for herself and her friends, or any combination of the above. The Ragtag Band of Misfits only stays together and follows her because they're all more or less equally broken.
Legacy Character: Blackjack is revealed to be a direct descendant of Twilight Sparkle and Big Macintosh. During the war, Twilight became pregnant but her cousin Marigold acts as a surrogant mother, adopting Twilight's child and named her Tarot. Tarot was eventually taken into Stable 99, and many years later, Blackjack was born.
Made of Iron: Blackjack can soak up a ridiculous amount of punishment, and she knows it.
Blackjack: I’ve had cyberponies blast me with artillery! I’ve been shot in the back by zebra snipers and taken an armor piercing round through my skull! I’ve had my face attacked by almost every single pony I call a close and personal friend! I’ve had boats dropped on me! Don’t you tell me what will and won’t kill me!
Rasputinian Death: A combination of cancer, mutation, multiple limb amputation, blood loss, pneumonia and finally, heart failure.
Really Gets Around: A heroic variant and major character flaw, stemming from her upbringing in Stable 99. Even after realising that 99 was a very poor example of how healthy sex and relationships work, BJ remains naive and is very easily seduced.
Red Eyes, Take Warning: Her standard eye colour. Becomes more pronounced after she becomes a cyborg. And again more apparent after being further augmented.
Sanity Slippage: Has moments of this, particularly when the stress, guilt, chem abuse, brain damage and taint contamination start piling up on her. She suffers recurring hallucinations and nightmares involving a stallion she calls the Dealer, due to his association with cryptic playing card-related metaphors, and in one case threatens him only to find that she's actually pointing her gun at Glory's head.
Spin-Offspring: Evidence seems to suggest that Blackjack is distantly descended from one of the Mane Six; Silver Stripe suspects Twilight Sparkle.
As of chapter 34 we know it is most probably not Twilight Sparkle as she was not able to open the door in Tenpony Tower. The most probable candidate aside from Twilight seems to be Rarity, as Fluttershy only ever had one daughter, Applejack never had a child before Stable 2, Rainbow Dash is rumored to be lesbian in-universe and Pinkie Pie is... well, not an option at all.
This is later revealed to be a ploy by her friends to keep her out of the Twilight Society's hands. She really IS Twilight's descendant.
Skilled, but Naive: Being from a Stable leaves her with no wasteland experience. She quickly adapts.
Super Drowning Skills: Having grown up underground, BJ is naturally a weak swimmer. Later Justified even further; her extensive cybernetics weigh her down enough that she immediately sinks. In chapter 36, she almost drowns in a (large, but relatively shallow) pool of blood.
Your Days Are Numbered: Twice. Once due to terminal illness, averted by her cyborg conversion, and again thanks to a soul-draining spell cast on her by Snips.
The oldest stallion in Stable 99, P-21 is used as a breeding tool and sex toy by the mares. Facing his inevitable "retirement", P-21 takes the opportunity to flee with Blackjack out into the Wasteland. A grumpy and deeply traumatised buck, P-21 is The One Guy in the team and keeps to himself, and Hates Being Touched. Later revealed to be Scotch Tape's dad.
Dark and Troubled Past: Spent his entire life as 'breeding equipment' in Stable 99, desperately trying to educate himself and find a way to escape before his 'retirement'.
Death Seeker: After the massacre of Stable 99, but Priest talks him out of it. Priest's death sends him right back over the edge, but taking responsibility for his daughter helps level him out again.
Doesn't Like Guns: P-21 outright refuses to use projectile weapons, even in desperate situations (though he takes to a Grenade Launcher after a little convincing). He restricts himself to weapons that require care and planning because he's afraid that his repressed hatred of Stable 99's mares might make him shoot Blackjack on impulse. Discovering that she once raped him and later beat his lover to death makes this a lot easier to understand.
Driven to Suicide: P-21 takes Blackjack's suicide attempt very badly, and shares a measure of her guilt over Stable 99. Fortunately, she manages to avert this trope at the last minute. He falls into Death Seeker mode after Priest is killed, but gradually gets better.
A pegasus who is a surviving member of the Volunteer Corps, Morning Glory joins Blackjack and P-21 shortly after their arrival in the Wasteland. An idealistic Combat Medic, Glory becomes Blackjack's marefriend and morality chain. She suffers a lot in the story.
Glory's relationship with Blackjack, which starts out as a Security Clingnote no pun intended on Glory's part, eventually develops to the point of involving rough BDSM, with Glory as the dominant partner.
Break the Cutie: Repeatedly. She loses her friends, her confidence, her innocence, her cutie mark, her family, her lover, the same lover again, her wing, her bodynote Though the transformation restores her wing, at least., and possibly a measure of her intelligence. Her mother is revealed to be a monster, and puts her father on life support indefinitely.
Gatling Good: After accidentally breaking Leo's AER-14 rifle, Glory buys a gatling laser, and later uses its barrel assembly to repair and upgrade the AER-14. Cue Beam Spam.
Lethal Chef: Only Blackjack can stand her cooking, due to BJ's bizarre sense of taste. After BJ's upgrades, Glory considers gemstones and metal to be valid ingredients.
That Pony is Dead: Changes her name to Fallen Glory shortly after her branding, claiming that things will be better for everyone if the Enclave believe her old self is dead. The name doesn't stick for long though, and most characters simply refer to her as Glory.
The Medic: Glory is an Enclave medical technician.
Hidden Depths: Glory is much more competent with medicine than she initially lets on, and performs a number of life-saving surgeries over the course of the story. This includes spinal surgery, skin grafts, tumor excision and lung and eye transplantsnote With the assistance of a priceless medical robot. She also assists Professor Zodiac and Rover in jury-rigging a life support system from Rampage's body and rebuilding Blackjack as a cyberpony, but the extent of her involvement in these procedures is unclear.
Parental Abandonment: Glory's mother Dawn left the Enclave when Glory was young. She eventually shows up in Chapel, looking for EC-1101.
A deeply troubled but powerful and immortal Reaper, Rampage is a daring and adventurous mare who likes to charge headlong into battle and is The Big Guy of Blackjack's team. She is in fact the end result of a soul-absorbing talisman made by Rarity, that contains several personalities of dead ponies and other creatures. This leads to a lot of mental problems for her, and has caused numerous tragedies for her in the past.
Anti-Hero: Type IV, with occasional lapses into Type V. Even at her most sane, she still displays some psychopathic tendencies.
Death by Origin Story: At least half a dozen ponies, including Twist, died in the process of creating Rampage. More recently, Rampage (presumably under control of the Angel of Death) killed her own daughter.
From a Single Cell: A small talisman in Rampage's chest can regenerate her entire body, even after she's disintegrated.
I Am A Humanitarian: Implied. Just where does Rampage's 'high-protien diet' come from? In the bar scene following the Battle of Flank (in which she single-handedly fought off the Pecos gang in a drug-induced frenzy), she vomits meat.
Would Hurt a Child: One of her personalities has a tendency to murder them, and is insane enough to believe that it's doing them a favor.
An alicorn and a member of the Goddess' Unity. She was asked by the Goddess to join Blackjack's group for the Unity's well-being. She is a quiet and reserved person, and wears a black lace dress to hide her alicorn form when in public and is skilled with a minigun.
Elephant in the Living Room: As with Fawkes in Fallout 3, nopony seems to pay much attention to the enormous, minigun-wielding alicorn following Blackjack around. Somewhat justified in that Lacunae makes an effort to conceal her wings.
Lacunae: One advantage to being a giant unicorn is that few bother you with why you are a giant unicorn.
Expy: Of Legion. Unique, friendly member of a Hive Mind race commonly seen as villains? Check. The Smart Guy? Check. Proficient with a sniper rifle? Check. Has trouble fitting in with others due to limited social understanding? Check. Disseminates herself so that her kind can live as whole individuals? Check.
Foregone Conclusion: The Goddess is going to die. How this will affect Lacunae remains to be seen.
Chapter 58 confirmed this trope with the Goddess' death. Lacunae survived the destruction of Maripony, only to willingly destroy herself to allow all of the removed memories to return to their rightful owners. Twilight Sparkle then takes over the body, saving Littlepip in Fallout Equestria.
Gatling Good: Spends several chapters carrying a minigun, but is eventually forced to leave it behind.
Meaningful Name: Discussed and Invoked. 'Lacunae' typically refers to something that is missing or omitted. Lacunae herself is a living repository for all the regretful memories that the rest of the Hive Mind would rather not dwell on.
Only Sane Mare: Lacunae is the only member of the party not to suffer from long term physical, psychological or sexual trauma. Naturally, this is often lampshaded but is, most likely, a temporary state.
Red-Headed Stepchild: Fulfills this role among alicorns, as in addition to being disconnected from their Hive Mind and her being sent to Hoofington (a place where the Goddess can't send any alicorns due to the constant psychic screaming that the city emits being harmful to them), she's also used as the dumping ground for all of the memories that the Goddess doesn't want to think about, whether they're Trixie's or Twilight's.
The Smart Guy: While P-21 and Glory are also contenders for this one, Lacunae has by far the greatest magical ability.
Woman in Black: Typically wears a mourners' gown to conceal her wings.
A filly who lives in Stable 99 and fixes the Stable's plumbing. She is taken outside by Blackjack and P-21 following the events in their home, and makes it her mission to find her talent to avoiding getting a toilet Cutie Mark. P-21's daughter.
Sole Survivor: Of Stable 99 (Not counting BJ and P-21, as they left voluntarily some time beforehand).
Took a Level in Badass: During the melee in Chapter 31, Blackjack asks her for help rebooting some Steel Rangers' disabled power armor. All Scotch can do is cower in fear inside a wagon. Shortly afterwards, just as Blackjack and Lacunae are about to be overwhelmed, the Rangers come to their rescue. Turns out that Scotchnote Who, notably, is a relatively small child with almost no combat experience managed to overcome her fear of the Rangers and assist them - right in the middle of a chaotic and bloody battlefield.
Baby Talk: As of chapter 62b, she can now say "Bwackjack".
Blank Slate: A rather extreme example, having no ability to do anything except eat food that's offered to her, sleep when she's tired, and hide from danger. She may be smarter than she appears, however, as she briefly manages to use a gun to protect (and shoot) Blackjack during a battle.
Kick the Dog: When Sanguine clones Blackjack for tissue to replace the skin damaged by pink cloud, he doesn't even bother to euthanise or (implicitly) sedate the clone first - essentially, he flays 'Blackjack' alive.
Pet the Dog: According to Psychoshy, Sanguine is her adoptive father and the only pony to ever treat her well. Cruellysubverted when he reveals that he was simply using her to gain access to Project Chimera.
Villainous Breakdown: Degenerates into a ranting, desperate mess as his attempts to get EC-1101 are foiled. He finally snaps and wipes out several towns just to get Blackjack's attention, then kills Priest when the negotiations turn ugly.
A pegasus who bears a striking resemblance to Fluttershy. She is a cruel and sarcastic Combat Pragmatist who has a thing for Sanguine. She is actually the child of Fluttershy and Goldenblood, believed to have died in premature childbirth, but was saved by Sanguine for his own plans.
A large group of raiders who dominate Hoofington, the Reapers were designed to fight off against other gangs in the wasteland and make it a better place. The Reapers are led by Big Daddy. They operate out the Hoofington Dome and often have gladiator battles. Rampage, Deus and Gorgon are all members of the Reapers.
An Enclave member who represents the pegasi community known as Thunderhead. A well-intentioned soldier, he wants to ensure Thunderhead survives against all odds, going to extreme lengths to achieve his goal.
Affably Evil: Lighthooves remains polite and well-composed most of the time and is quite willing to negotiate when convenient.
Enemy Mine: He rescues Blackjack and Glory from Chapter 29's Literal Cliffhanger and establishes a mutually beneficial arrangement to preserve Thunderhead against the Enclave proper.
May I rant a little? I think that, since you’ve seen fit to give me the role of a villain, I’m entitled to give a little explanation?
Playing with Syringes: Afraid that the Enclave military at large is planning to attack Thunderhead, his goal is to adapt the raider virus to infect pegasi, presenting a more direct threat for them to focus their attention on. Chapter 42 reveals that he has succeeded, and that his agents used Neighvarro pegasi as test subjects.
Well-Intentioned Extremist: In Chapter 30, he explains in his Motive Rant that everything he's done has been to protect Thunderhead in hopes of sustainable surface contact in the future. Granted, the details include a fair amount of genocide, but still, it's enough to convince Blackjack to call a truce.
Star Paladin Steel Rain
A cruel Steel Ranger who is working for Cognitum and the Harbingers. He is a powerful opponent and becomes a recurring enemy for Blackjack.
BFG: Carries a pair of anti-dragon autocannons on his armor. Apparently they can vaporize a pony from two miles with near-perfect accuracy. See Gun Porn.
Gun Porn: Goes into exquisite detail explaining the capabilities of his BFGs.
Steel Rain: Do you really think a gun like this should be left in a weapons locker to collect dust?
Hero Killer: From his first appearance, Blackjack is noticeably intimidated by him. After cornering her on the HMS Celestia, he cripples her with a single shot and comes very close to killing her outright; she pulls a Taking You with Me, which he survives.
Implacable Man: In their first encounter, BJ blows off his helmet and barely slows him down. In the second, he shrugs off anti-material rounds and proves a match for Rampage in close combat.
Kick the Dog: Daisy breaks P-21's leg for no particular reason in the first chapter. Later, Daisy makes Blackjack eat Rampage's heart to maintain her raider disguise despite knowing who she is, and the Overmare rapes P-21.
An enigmatic figure from the war, Goldenblood was director of the Office of Interministry Affairs (or O.I.A.) and aided joint projects between the Ministries. He was a survivor of the Littlehorn Massacre, but was infected with Pink Cloud and spoke is a raspy voice and was deathly ill. Had a doomed relationship with Fluttershy. He was a master of manipulation and very secretive.
Freak Out!: According to Sanguine, Goldenblood completely lost it after being arrested for treason.
From Nobody to Nightmare: Over the course of the war, Goldenblood changed from the obscure bastard son of Prince Blueblood, to a geology and history professor, to one of the most influential and subversive govenment officials in Equestria.
Manipulative Bastard: Oh yes. For reasons not yet known, Goldenblood had a significant influence on Luna's government reforms and the formation of the ministries. He is also known to have wiped Twilight's memories of creating the Gardens of Equestria, and blackmailed Rarity over her posession of the Black Book.
Offing the Offspring: Subverted. Calling out another mare's name while intimate with a pregnant Fluttershy caused her to go into premature labor. Both Goldenblood and Fluttershy were lead to believe that the resulting birth was a miscarriage, and mourned as such. In fact, Trueblood (later Sanguine) actually kept the infant Whisper (later Psychoshy) in secret to further his own ends.
Posthumous Character: Maybe. So far all we've seen of him has been in pre-apocalypse memory orbs and recordings.
A mysterious skeletal pony who wears a battered hat and coat, the Dealer materialises shortly after Blackjack downloads EC-1101 into her PipBuck and has a flipflopping view on her efforts to do good. Blackjack assumes he is death incarnate but learns he is a pre-wasteland spirit attached to EC-1101 to ensure it reaches its proper destinations.
The Atoner: As Echo, he believes he stood by and did nothing as his team disintegrated around him, and he had a very miserable life.
A group of various individuals who work for Professor Zodiac. While they are introduced as antagonists targeting Blackjack, they are good people at heart. Each member is named after a star sign of the western zodiac.
The kindly leader of the small settlement named Chapel, Priest created a safe haven town for refugees and others who he refers to as "Pilgrims". He works as a priest for Princess Celestia and Luna, restoring the town's chapel to its pre-war state. He tries to dissuade Pilgrims from taking "The Journey" but will not stop them if they decide to do it.
Big Fancy House: Priest gives his old house, Star House, to Blackjack to live in. Twilight Sparkle's cousin Marigold once lived in the house.
Driven to Suicide: Priest tries to convince Pilgrims from not partaking in the Journey, but will not force them to stop if they decide to go through with it. The Journey itself involves the Pilgrims walking across the bridge leading to Hoofington's Core, where the deadly disintegration weapons will instantly kill the Pilgrims.
Due to the Dead: Built a graveyard in Chapel for those who take the Journey.
The Vicar: Fills this role in the Fallout Equestria world. He is a priest of Celestia and Luna, founded the town and built it around the chapel that it is named after, has the colours of a vicar's uniform, and his Cutie Mark is a silhouette of Celestia raising the sun.
A civilized faction living in Hoofington, the Society believe themselves to be the rightful and future leaders of Equestria. They are led by the elderly King Awesome and most are descendants of pre-war Equestria's aristocracy. Awesome has three children.
Affably Evil: Beyond the slavery, the Society are probably one of the nicer factions that Blackjack meets. They want to restore Equestria, share the Fluttershy Medical Centre with the Collegiate, and grow fresh fruit to trade with other factions including the Enclave.
Bratty Half-Pint: Princess Charm. A bratty self-centered filly who believes she should be King Awesome's successor because she just should. She even kidnaps Scotch in an attempt to make Blackjack pick her, but Blackjack easily defeats her and lets Rampage and Scotch torture her.
Servant Race: The Society started off as slavers, but thanks to King Awesome, their methods were altered so the slaves would be known as serfs. They had better priviledges but were still slaves, and wore bomb collars.
Sheltered Aristocrat: Subverted. Most members of the Society are well aware of the harsh conditions of the Wasteland but do their best to just live out their lives normally.
Unexpected Inheritance: After King Awesome dies, he deliberately makes Blackjack queen of the Society, so she can sort out the troubles of the faction and to fairly decide which of his children should ascend the throne. She picks Grace.
A special squad consisting of all three species of pony, designed for the purpose of special ops and combat. Led by Big Macintosh, the group formed a family-like unit over the course of the war. However, tragedy ended up destroying the squad following Big Macintosh's death at Shattered Hoof Ridge. The rest of the squad either died or suffered horrible fates, some appearing two-hundred years later in the Equestrian Wasteland.
Doomed by Canon: Like most of the pre-Wasteland cast, the Marauders all suffer terrible fates that leave them either dead, insane, emotionally broken or are mutated into alternate forms. See Posthumous Character below.
Fallen Hero: Most of them eventually become examples of this.
Posthumous Character: As Macintosh's Marauders existed during the Great War, all of Blackjack's encounters with them are through memory orbs and apocalyptic logs. Though many of them are actually still alive, the intervening time has changed them to a point where they are no longer recognisable.
By the start of the story, Big Macintosh (took a bullet for Princess Celestia) and Vanity (stabbed by his brother Blueblood) are both dead; Jetstream went nuts and sent off by Garnet to bomb the zebra capital as part of a "rescue mission"; and those who were still alive in numerous forms, Applesnack (Fallout Equestria's Steelhooves), Doof (Deus), Twist (part of Rampage), Psalm (Lacunae), Stonewing (Gorgon), and Echo (The Dealer).
Leader of the Macintosh's Marauders, Big Macintosh is an intelligent, strong and respected sergeant of little words. He is big brother of Applejack and Apple Bloom. He was the heart of the squad and the others idolised him. However, he infamously died defending Princess Celestia at the botched Shattered Hoof Ridge peace talks, leading to the destruction of the squad.
Breaking the Fellowship: Echo explains to Blackjack that shortly after the creation of the Marauders, they went to a funfair and met a zebra fortune teller. He told them that they would become famous and help win the war, as long as they remained true to one another and kept their fellowship together. However, he forewarned that if the fellowship was broken, the first to break it would die a peaceful death while the others would suffer unimaginable fates. It was first believed Stonewing broke the fellowship with his "death", but it turns out Big Macintosh was responsible with his plans to retire. He died in the most painless death of the squad via a bullet to the head.
Heroic Sacrifice: Said to have died like this during the battle at Shattered Hoof. Turns out this is actually half-true. Big Macintosh defended Princess Celestia from zebra assassins, only to end up taking a bullet fired by Psalm, who thought a dead Celestia was better than a captured Celestia.
Big Macintosh's lieutenant, Applesnack is a cynical, gruff and moody earth pony who is openly racist towards zebras. He dated Applejack during the war. Would later become the first Steel Ranger and used the alias Steelhooves.
BFG: Owns a few, before and after becoming Steelhooves.
The youngest member of the Marauders, Twist is an old friend of Apple Bloom and had a lifelong crush on her. She spoke with a speech impediment and wore glasses, but got rid of both to not be a liability to her team. Dated a Proditor zebra named Shuuja.
New Meat: She was the youngest member of the team.
Posthumous Character: Shuuja was killed by a racist mare during a mission to meet a tribe of zebras hoping to allegedly join Equestria's forces. Twist was also shot and close to death, only for Shuuja to rip out the regenerative Phoenix Talisman and give it to Twist, dying herself. Twist later died at Miramare Air Station on the Last Day, and her soul along with the talisman, ended up in Rampage, actually her daughter Peppermint.
Rape as Drama: Thanks to Doof's own stupidity and Brass' manipulation, Twist was unintentionally raped by Doof, leading to Doof's incarceration and Twist's fear of her former best friend.
Sweet Tooth: Often munched on peppermint sticks and mint-als. She owned a candy store in Hoofington with Doof before it was burnt down.
A large, simple-minded stallion who was friends with Twist and Psalm. He acted as the Dumb Muscle of the team, and had a crush on Twist. Following Big Macintosh's death, Doof was tricked by Brass into raping Twist, was imprisoned in Hightower Prison, and then was used as a guinea pig in Project Steelpony, becoming Deus Ex Machina.
All Love Is Unrequited: Doof loved Twist, even though she only saw him as a friend and repeatedly rejected his feelings. Unfortunately, Doof's limited intelligence led him into being manipulated by Brass into raping Twist.
Big Bad: For the first arc of Project Horizons. He returns with his mind programmed into a tank, though thanks to Blackjack seeing him as a pony, he has a Heel-Face Turn.
From Nobody to Nightmare: After raping Twist, poor Doof was imprisoned in Hightower Prison to rot. He pleaded with Vanity to let him see Twist for beg for forgiveness, but was denied. This led to him becoming a monster, believing all mare were "cunts" including Twist, and he was put in solitary confinement to prevent him from harming anyone. He was then selected for Project Steelpony, becoming the deadly Reaper known as Deus.
A quiet unicorn who acts as a sniper for the Marauders. Psalm is old friends with Twist, and is a very religious mare, worshipping Princess Luna mostly and always begs for forgiveness whenever she kills or harms someone.
Apologetic Attacker: Psalm prays to Celestia and Luna for forgiveness whenever she takes a life.
The Atoner: Really wants to become this but believes Luna will never forgive her.
Faith Heel Turn: Psalm has a Despair Event Horizon and breaks emotionally after killing Big Macintosh. The day after, she abandons the rest of her team and becomes an emotionless sniper following the orders of Luna, carrying out Project Partypooper.
Karmic Transformation: Psalm is forced into Unity by the Goddess, earning her "forgiveness", and becomes the building block for what would become Lacunae.
Kill 'em All: Psalm carries out Project Partypooper, designed to eliminate those who are meant to wield the EC-1101. She learns the order was issued by Garnet, but after shooting Garnet and leaving her to die, Psalm goes to Maripony to kill Twilight on a suicide mission.
One of the Marauders' two pegasus members, Stonewing and Jetstream acted as aerial support and were a perfect tag team. He lost his voice when he took a bullet to the throat, and then his life when blindsided in a later battle. He actually survived and was used by Sanguine as the first test subject in Project Chimera, fused with a cockatrice and became Gorgon.
Cruel and Unusual Death: As Gorgon, Blackjack forces him through a rock grinder. She later finds a farewell letter from Stonewing thanking whoever killed him.
Oblivious to Love: Stonewing idolised Rainbow Dash, and remained oblivious to Jetstream's love for a long time. However, he realised when she started resting her head on his shoulder. When she confesses, he rejects as gently as possible.
All Love Is Unrequited: Jetstream loved Stonewing since she first met him, but he was oblivious to her affections since he was focused on Rainbow Dash.
Broken Bird: Loses her true love and has her memories erased of him, Big Macintosh dies, and she has a mental and emotional breakdown.
Laser-Guided Amnesia: Jetstream was so distraught by Stonewing's death that she asked Vanity to remove the memories of him. Vanity reluctantly agreed, but this only led to Jetstream's mental breakdown.
Love Triangle: Jetstream loves Stonewing who loves Rainbow Dash, while Vanity loves Jetstream.
Put on a Bus: While in the Happyhorn Gardens, Jetstream is approached by Garnet who lies to her that Stonewing and Big Macintosh are imprisoned in a zebra prisoner war camp and sends her off to fly off and "rescue" them. After Jetstream leaves, Garnet implies Jetstream is doomed since the Last Day occurs in four days time.
Sanity Slippage: She slowly went insane following Stonewing's and Big Macintosh's deaths. Much to Vanity and Echo's regret, she was eventually put in the Happyhorn Gardens mental hospital where she believed she was still on duty with all of her teammates alive.
Goldenblood's uncle and Prince Blueblood's brother. Vanity is a royal aristocrat who becomes the moral officer of the Marauders. While proud, he is a very kind and generous unicorn in comparison to his snobbish brother.
Officer and a Gentleman: Incredibly curteous, polite and kind. He defends his friends against Blueblood's pompous insults, and aids his servants and a group of fillies in fighting off an angry mob during the Last Day.
Screw This, I'm Outta Here!: After Big Macintosh's death, Jetstream's breakdown, and Twist being raped by Doof, Vanity just quit the team out of emotional exhaustion, though he kept in contact with his teammates.
Shut Up, Hannibal!: Wrote an unsent a resignation letter to Mr. Horse, telling him to get to hell for screwing over tons of ponies with Project Redoubt.
Secret Keeper: Claims to know most of the Marauders' darkest secrets but did nothing to bring them to light to help his friends. Eventually he was hired by Goldenblood as his assistant, learning many of the O.I.A.'s secret projects including that Stonewing was alive.
Soul Jar: His spirit was attached to EC-1101 by Goldenblood.
And I Must Scream: Discord is at the heart of Project Chimera, being used as the source for the Bio-Magical Flux.
Break the Cutie: Fluttershy. A moment of indiscretion from Goldenblood destroyed their relationship and cost them their unborn daughter.
Cyborg: Rover, the red-vested diamond dog leader who once kidnapped Rarity, has survived the apocalypse and two centuries in the wasteland thanks to his augments. He's pretty much the only surviving Friendship is Magic character seen in either the main story or Project Horizons to be more or less still himself, instead of becoming a ghoul, alicorn drone, computerprogram, tree, or Rampage.
Facial Horror: Silver Spoon and Prince Blueblood have both become ghouls. Silver Spoon is a Glowing One whose glasses have been melted onto her face. Blueblood's facial decay has left him with a permanent, ear-to-ear Glasgow Grin.
Not Quite Dead: Octavia. While Blackjack finds her skeleton, her contrabass is actually her Soul Jar. After realising this, Blackjack gives the instrument to the Crusaders so that Octavia will always have someone to look after her.
Snips, likely thanks to the Black Book, has managed to cheat death, and picked up not only a pair of huge shears that do exactly what you think they would do to flesh, but also a repertoire of Black Magic.
