Warrior Nun is a Netflix series that is based on the comic book Warrior Nun Areala. During a terrible battle in a morgue between warrior nuns and demon-haunted mercenaries, dead nineteen year old quadriplegic girl Ava is implanted with a mystical halo. She quickly finds herself Back from the Dead and fighting for her life, before escaping into the Spanish streets.
Confused by what's happening to her, she has to juggle whether to grasp the opportunity to be a normal teen or become the Warrior Nun, a leader of the forces for good in the ancient battle between Heaven Versus Hell.
In August 2020, the series was renewed for a second season.
- Adaptational Heroism: Technically happens in translation as the Julian Salvius of the comic books was a much darker figure than the show's version, Jillian, who is a morally grey CEO. Julian was a immortal pagan Roman Emperor hell-bent on revenge against the Catholic Church while Jillian just wants to open a portal to Heaven so her sick son can live in peace; she is actually pretty chill (well, most of the time) towards Ava and the nuns once they find common ground.
- Adaptational Modesty: Compared to the original comic where the nuns were more Naughty Nuns, the OCS members here all wear more traditional attire that is far more modest and allows them to walk around in public without getting too much attention from others.
- Annoying Arrows: In many of Areala's memories of medieval combat, she'll pull arrows out of her body without even slowing down. Adriel goes one better and pulls an arrow out of his head when he fights the nuns due to the fact that he's basically a demon/extraterrestrial/inter-dimensional being/whatever.
- Back from the Dead: Ava is implanted with the halo after having died and is brought back to life. Lilith also returns after being gut-stabbed and dragged to Hell by a Tarask. This finally gives the pair some common ground after their previous strife.
- Badass Preacher: Father Vincent looks pretty bookish, but does very well for himself whenever he needs to fight. Being a former cartel enforcer will do that.
- Big Bad: The nuns spend the series working hard to bring down Cardinal Duretti's before he can achieve his goal. While they can't stop his career plans, they're determined to stop his more secret ones. They're therefore completely blindsided when they discover that the Big Bad is actually Adriel, the being who gifted the Halo to Areala and whom the resulting Warrior Nuns believed was a hero and an angel. He's a thief with his own agenda and the events of the first season, including the framing of Duretti, is engineered by his servant, Father Vincint, for the purpose of freeing him.
- Bolivian Army Cliffhanger: The first season ends with a stand off between the heroes and the villains. The nuns confront a crowd of people in the Vatican that are controlled by Adriel's wraith demons. The final shot is of Mary being overwhelmed.
- Christianity Is Catholic: The Order of the Cruciform Sword is a Catholic order. Everything revolves around the Catholic Church, it's history and the Vatican's internal politics. No other form of Christianity is mentioned, even though other non-Christian religions are very briefly acknowledged.
- Deadly Doctor: Nurse Francis, who took care of Ava at the orphanage, was a pretty awful bitch who wasn't sorry when Ava died on her watch. She's a serial killer who murdered a large number of orphans in her care (including Ava) as they aged out of the orphanage. She claimed it as an act of mercy, that those orphans would have had no chance to survive outside her care.
- Demonic Possession: Wraith demons have the ability to possess humans and force them to do whatever they want. Outside the body, they exist as red smoke that can form demonic shapes. Only the Halo-Bearer can see them; it's her job to direct the rest the of the nuns in battle by acting as their eyes.
- Double Agent: The only thing the nuns are sure of is that Sister Shannon was assassinated and that it had to be an inside job. The first season consists of them struggling to figure out who the agent is and what Cardinal Duretti stands to gain from her murder. The double-agent, and Shannon's murderer, turns out to be Father Vincint, who is working for Adriel, a being that is very far removed from the angel the Order believes him to be.
- Evil All Along: After being warned by the dying Shannon to trust no-one, Mary spends the first season hunting for the insider who is responsible for her death. It turns out to be Father Vincint, who murdered Shannon because she discovered what was hidden beneath the Vatican Church and what it meant for the origin of the Order.
- Fantastic Catholicism: There is a secret order of fighting nuns who protect the halo of an angel, which gives their the power to see and fight the demons of Hell. Holy Relics have real power and the Catholic Church is sitting on thousands of years of knowledge regarding the supernatural battles with Hell for humanity's soul.
- Gender Flip: Originally male in the comics, Julian Salvius becomes a female CEO called Jillian in the show; one of her issues with the Catholic Church is the dominance of men holding back science and feminism.
- Good All Along: Jillian Salvius is a potential enemy of the nuns because she she is collecting Divinium to create a portal and desperately wants Ava for her ability to activate the metal. She's actually trying to save the live of her terminally son; once she and the nuns find common ground, she becomes extremely helpful.
- Good Is Not Nice: The nuns are fully willing to beat the crap out of Ava to teach her a lesson. Or shoot a dude in the face and throw him off a cliff once they have all the info they need from him.
- Gratuitous Greek: Arq Tech. The 'T' is a 'T' overlaid with a Greek psi. Meaning it's Arq Ps-Tech.
- Idiosyncratic Episode Naming: Each episode is named after a Bible verse, which relates to a subject relevant to that episode.
- Involuntary Shapeshifting: One human who undergoes a life-altering experience finds themselves beginning to transform without even wanting to. It terrifies them even more than it does the nuns. Sister Lilith is impaled and dragged away from Earth by a Tarask. When she returns, her hands begin manifesting claws without her consent, and her hair rapidly begins changing colour.
- In with the In Crowd: JC's group are fun-loving party-goers who live in the fast lane and go to all the coolest joints in town. Ava is thrilled when she hooks up with them, finally experiencing the life she was previously denied while trapped in the orphanage.
- Legacy Character: The Halo is passed from one Warrior Nun to the next. At some point, the current Warrior Nun will always meet the previous one in a vision.
- Meaningful Name: Lilith is named after a demon in Jewish folklore who was originally made from the same material as Adam and left the Garden of Eden due to her pride. She constantly chastised by the nuns for being driven by pride, which makes it almost impossible for her and Ava to get along. She eventually acknowledges that pride is a real problem for her.
- And just like the Biblical Lilith, she seems to have consorted with demons, or at least been healed and sent back by them.
- Mundane Utility: Mary has a dagger made out of Divinium. It can kill demons. She uses it to hold a bird she cooked over a campfire while she pulls the meat off it.
- One Dialogue, Two Conversations: In the first season finale, Mother Superion confronts Duretti on everything he's done from killing Shannon to Vatican secret he's trying to steal for himself. Duretti is completely baffled; he's only been consolidating his political power to win the papal election. It's only when he asks Superion who is behind her accusations that the Awful Truth dawns on her — the real villain is Father Vincent, who directed the nuns to mistrust Duretti so that he could succeed in his plans.
- The Order: The series revolves around the Order of the Cruciform Sword, a secret Catholic sect of nuns trained to fight demons, led by a lineage of those chosen to wield an angelic Halo.
- Our Demons Are Different: The Tarask and wraith-demons. The Tarask is capable of taking physical form and has a more traditional demonic, minotaur-esque form. Wraiths are insubstantial and invisible to normal people, able to act only through the humans they possess. Both can be defeated by the Warrior Nun with a Divinium weapon.
- Power Walk: In "Corinthians 12:4", the heroes have a slow-motion walk to dramatic music as they rip off their demure clerical garb to reveal their fighting outfits underneath. This includes Father Vincent discarding his collar and unbuttoning the top two buttons of her shirt.
- Pun: Sneaking into the Vatican as a priest and group of nuns leads to Ava making increasingly terrible puns about their infiltration. By the time they're into the catacombs, she's graduated to making so many dead jokes that Beatrice starts joining in — much to Ava's delight.Beatrice: Don't fidget. Nuns don't fidget.
Ava: Sorry. Bad habit. [grin]
Mary: I should shoot you for that.
- Race Lift: In the original comic, Shotgun Mary is white; in the show, she's played by a black actress.
- Reassigned to Antarctica: During his takeover of the order, Duretti has the most loyal members transferred. Sister Beatrice is ordered to Malaysia (where the OCS has no presence), and Father Vincent to Florida.
- Red Herring: The nuns find themselves dealing with several people who don't turn out be quite the people they initially thought they were. The most significant is Cardinal Duretti, who is politically ambitious, knows about the secret Order and actively sabotages it by reassigning its most competent, but independent, members while bring in rejected candidates who are loyal to him. The nuns send the season working out what he's up to and how to stop him achieving his dastardly goal... until it turns out that he was only interested in the political situation and was being set-up by the real villain, Father Vincent.
- Saintly Church: How virtuous the Catholic Church appears varies over time, based on what various characters know or feel. They're initially introduced as monster-killers who have some deadly serious internal politics. The nuns end up uncovering a vast supernatural conspiracy at the heart of the Vatican centred on hiding the resting place of the angel Adriel's bones, which keeps demons attacking earth and therefore ensures the Church stays relevant in the eyes of the fearful. And then the season one finale reveals the real reason why the Church has been keeping Adriel buried beneath all that stone...
- Sealed Evil in a Can: One method for dealing with evil involves sealing it away forever so that it can't do any damage. The reason reason Adriel has been entombed underneath the Vatican is because he is not dead and he is not the angel the Order's texts portray him to be. He's evil, he controls demons, and the entire first season is the unfolding of his plan to escape his prison.
- Shout-Out: Ava's room at the orphanage has a cool poster of George Orwell on the wall above her bed.
- Snark-to-Snark Combat: Ava has a sarcastic quip to make about absolutely anyone and anything. She meets her match in Mary.Father Vincent: Ah, Ava, good, come on in. Let me introduce you to Sister —
Mary: Shotgun Mary.
Ava: Cool name. Why do they call you that?
Camera: [lingering shot of Mary, clearly showing a shotgun on either hip.]
Mary: I drink a lot.
- Technobabble: When Ava decides to get the Halo's power scientifically assessed, Jillian declares "This is a quantum expression of Newtonian force", which means... fuck all.
- Training from Hell: Ava's very first training session involves getting beaten with a baton to try and get her to activate her Halo powers.
- Worst Aid: Discussed in the first episode. Mary wants the Divinium shrapnel taken out of Shannon's body before it kills her as its presence in her body prevents the Halo from healing her. However, it's pointed out that the location of it is also the only thing keeping Shannon from bleeding to death. If they remove it, she dies. If they leave it in, she dies.
