Warrior Nun is a Netflix series 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, fighting for her life, and running into the wild streets of somewhere in Spain. An unfortunate encounter with a truck shows her that she can phase through walls and heal from serious wounds. Then she falls in love with a cute boy.
Ava is now part of the battle of Heaven Versus Hell, the Warrior Nun intended to lead a cadre of the same (though less powerful) in the fight against demons.
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 immortal pagan Roman Emperor hell-bent on revenge against the Catholic Church but the show's Jillian is a morally grey CEO who just wants to open a portal to Heaven so her sick son can live in peace, and 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: Happens with many of Areala's memories of Medieval combat. More than justified by Adriel, who 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.
- 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: Adriel, the being who gifted the Halo to Arela and started the line of Warrior Nuns, only did so to further his own agenda. Everything that happens over the course of the first season is engineered by him through Vincent to free himself from his imprisonment.
- Bolivian Army Ending: The first season ends with the nuns confronting a crowd of people controlled by Adriel's wraith demons in the Vatican, with the last shots being of Mary getting overwhelmed.
- Christianity Is Catholic: Or at least that's what we see in the show. The Order of the Cruciform Sword is a Catholic order.
- Deadly Doctor: Nurse Francis, who took care of Ava at the orphanage, was a pretty awful bitch the whole time. No one was really surprised to learn that she's also 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.
- Death by Flashback: This gets averted when Ava experiences the memories of Areala, who almost died before Adriel put the Halo in her back.
- Demonic Possession: Happens with the wraith-demons, which only the Halo-Bearer can see.
- Double Agent: Turns out Father Vincent was working for Adriel, who certainly isn't the angel the Order claimed.
- Evil All Along: Father Vincent. He murdered Sister Shannon when she discovered what was hidden beneath the Vatican Church. And he is a servant of Adriel, the Fallen Angel behind the Halo's existence.
- Fantastic Catholicism: Well, duh.
- Gender Flip: They flipped the character of Julian Salvius to become Jillian Salvius.
- Good All Along: Jillian Salvius is presented as a potential enemy of the nuns due to her desire to claim Divinium for her portal, but it turns out she only wants to build said portal to save her son, and aids the nuns once they find common ground.
- 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: This seems to be happening to Sister Lilith after she returns from... wherever the Tarask took her. Her hair is changing color, her nails grow out instantaneously, and she has developed the ability to teleport.
- In with the In Crowd: Ava, when she briefly hooks up with JC and his crew.
- Legacy Character: The Halo is passed from one Warrior Nun to the next.
- Meaningful Name: Sister Lilith, 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.
- 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 the power of the bones. At which point, a baffled Duretti asks "what bones?" This has never been a sinister plot for evil for him, merely collecting his political power to win the papal election. He asks Superion who has been saying he's the one behind all this and she falls into Oh, Crap! when she realizes it was always Vincent making Duretti out as the bad guy.
- 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, obviously. The Tarask is corporeal and somewhat resembles a Balrog. 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.
- Our Zombies Are Different: The way some people behave when under the control of wraith-demons is arguably this.
- Power Walk: In "Corinthians 12:4", the group gets one as they infiltrate the Vatican, complete with dramatically removing their robes and Ava's hood - in Father Vincent's case he also removes his priest's collar and undoes the top two buttons on his shirt.
- Pun: Sneaking into the Vatican as, what else, a priest and a group of nuns.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; here she's played by a black actress.
- Raised Catholic: The reason Ava got stuck in a Spanish orphanage run by nuns in the first place.
- 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: Done convincingly with Cardinal Duretti. He is presented from the beginning as the season's potential Big Bad. He is ambitious and clearly wants to be the next Pope. He is quick to replace the main Warrior Nuns with new members who were rejects, because they won't question his orders. And it seems like he is hiding something. Eventually, the Nuns believe he is the one who murdered Sister Shannon. Nope, turns out he was just an ambitious member of the clergy and nothing more. The true traitor in the Vatican and murderer of Sister Shannon is no other than Father Vincent.
- Saintly Church: Double Subverted and zig-zagged. How virtuous the Catholic Church appears varies over time. At first they're very clear-cut as monster-killers, but with Cardinal Duretti scheming and undermining the O.C.S., the main characters begin to suspect the Church has been hiding the angel Adriel's bones so that demons can come to Earth and continue scaring people into faith. As it turns out in the finale, the Church had a very good reason to keep Adriel buried under that much stone.
- Scenery Porn: Episode 6 has a lot of lingering shots of southern Spain. It's fucking gorgeous.
- Sealed Evil in a Can: Turns out that Adriel, the alleged angel who gifted the Halo to the O.C.S., is one of these. He doesn't stay sealed, either.
- Shout-Out: In a somewhat blink and you'll miss it shot, Ava's room at the orphanage has a cool poster of George Orwell.
- Snark-to-Snark Combat: Ava and Mary both love to snark. So when they meet...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.
Vincent: [rolls his eyes]
- Technobabble: Regarding the device and Ava's connection to it. "This is a quantum expression of Newtonian force." This...means fuck all.
- The Crusades: Appears briefly in the Flashback Cut of Areala, the first Warrior Nun.
- 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.
- Wham Episode: Episode 10, the first season finale. In summary, Adriel, the supposed angel who gifted the Halo to Arela and started the line of Warrior Nuns, is actually more of a devil figure who only did so to build himself a loyal army, before he was sealed under the Vatican to imprison him. He gets loose thanks to Ava's unwitting help, at which point it's revealed that Cardinal Duretti, while corrupt, had nothing to do with him — but Father Vincent did, having killed Sister Shannon to start the chain of events leading to Adriel's release. The season then ends with Adriel unleashing a small army of wraith demons to overwhelm the nuns.
- Wham Line: "My Master." Vincent to Adriel.
- Worst Aid: Averted in the first episode. The Divinium shrapnel in her body is the only thing keeping Shannon from healing, but it's also the only thing keeping her from bleeding to death. If they remove it, she dies. If they leave it in, she dies.
