Academy of Evil: The HIVE. Jade is actually surprised at how much like a regular school it is.
Affably Evil: Gadjo is psychotic, but when he's not trying to kill you, he seems like a pretty fun guy.
Alternate Universe: The Titans universe is this to the JCA universe. The point is hammered home when Jade realizes the Jump City is the counterpart to San Francisco, with Titans Tower revealed to be where Alcatraz is supposed to be.
Another major difference is that in the TT universe, chi magic died out a couple centuries prior to the modern day.
Another Dimension: The pocket dimension Jade ends up in in the prologue — it consists solely of a small island floating in a multicolored void.
We finally get a glimpse of the shadow realm when Jade flees there after getting hit with an onion. It appears to consist of islands, covered in mountains and jungles, floating in shadows that seem to shift between air and liquid composition. And it appears to be toxic to non-Shadowkhan, whom the shadows burn (while at the same time granting Shadowkhan increased power and a Healing Factor).
Anti-Villain: Jade is a definite Type IV. She'd very much like to not be a villain at all, but circumstances forced her into the role, and have been keeping her in it.
Baleful Polymorph: The Cackler forcibly transforms Jade back into her Shadowkhan form (although she still has her normal mindset).
She also gets turned into a monkey by Mumbo (to serve as his assistant), but that is undone rather quickly.
Be Careful What You Wish For: Jade thinks this whole situation is the universe saying this to her in regards to her wish for an exciting life.
Berserk Button: Jade suddenly seems to have a whole bunch of them. Her transformation and the stress of her situation seems to have given her a seriously short fuse. Naturally, this doesn't help her situation with the Titans any.
Big Bad: Brother Blood seems to fulfilling this role for the time being.
Bigger Bad: The Cackler, possibly. It's not very clear at this point.
Black and White Morality: Robin's viewpoint, as Raven lampshades during the tournament. Subverted with Raven herself, as she understands that there are villains with standards out there, and not all villains are all bad (like Jade), and that you generalize like Robin does at your own risk.
Machete is also extremely violent (fittingly, she's assigned to be Gadjo's partner), to the point she'll attack her fellow HIVE students if they get in the way of her attacking someone else.
The Brute: Mammoth and Gadjo. Also Susano, to an extent. And while we haven't seen much of Machete, from what little we have seen, she appears to be a rare female example.
Bullying a Dragon: The hot dog guy Jade met was really rude to her over five cents, leading to her accidentally blowing up his cart with the Dragon talisman, not to mention the random residents of the city.
Kitten, after having been stopped nearly effortlessly by Jade in the Tournament of Villainesses (Jade used heat vision to blast away Kitten's energy whip and then picked her up with the Rooster Talisman), proceeds to insulther! The evil teen insulted Jade's outfit and appearance (the appearance part in multiple ways), her power set, and was starting to say that Jade was so ugly that that was why she wan't in her original dimension, they had kicked her out (she didn't finish, but it's clear what she was saying), before Jade's Berserk Buttons were fully pressed and she unleashed a Dragon Talisman blast that nearly killed Kitten, giving Jade a My God, What Have I Done? moment (as, unlike the others Jade had met, the evil blonde was notMade of Iron). And this was AFTER Jade had offered Kitten a chance to surrender!
The Cameo: Zatanna shows up in the Tournament of Villainesses chapter when Robin asks for her help in finding Raven.
Georgia, another contestant of that same event, is the daughter of Captain Marvel's Arch-Enemy.
Clingy MacGuffin: Jade had the Rooster, Dragon, and Pig talismans on her when she was sent across dimensions, and after the Cackler's interference, they end up fused into her body.
Machete's suit is apparently another example, as Robin mentions that they cannot remove it.
Clothing Damage: During Jade's first fight with the Titans, Robin hits one of the Talismans (presumably the Dragon), which causes an explosive release of energy that — among other things — fries most of her clothes.
This leads Jade to make sure her new costume is fire retardant and otherwise durable, to avoid any repeats of such an event.
Combat Sadomasochist/Too Kinky to Torture: Gadjo. He gets electrocuted by Susano during the entrance exam fight, and laughs through it, and when he's later thrown into the Pit for a week, Mammoth comments that the only reason he probably doesn't break out early is because whatever goes on in there, he probably enjoys it.
Continuity Nod: When Jade realizes she's been accidentally banished in the process of banishing a demon, she's upset that it's happened again, a reference to the time she was banished to the Netherworld along with Bai Tza.
When she first tells Jinx she knows magic, she mentioned the chi zapper she made from a flower to battle the Earth Demon.
She's also not happy when she gets turned into a monkey by Mumbo, remembering the last time it happened (the original Monkey talisman episode).
At another point, she lists all the spells she's learned and used over the course of the show.
Jade also mentally compares and contrasts the shadow realm of the TT world and the Demon Netherworld.
The Queen compares herself to Tiger (Jackie's dark half brought to life by the Tiger talisman) when trying to convince Jade she's not so bad.
During the chapter that introduces the Master of Games, Jade briefly compares him to the Monkey King.
Crossover: Obviously. But in addition to crossing over JCA and TT, it also partially crosses over with another story by the same author — the evil adult Jade who appears in the "Destiny" interlude is (or is based on) the Cult-leading adult version of Jade who appeared in the oneshot "When I Grow Up".
In Jewel Of Darkness, some of Susano's comments in regards to the Missing Episode of that story implies that the Susano from that story and this one are the same individual (he mentions a gypsy and an "Oni spawn", which likely refers to Gadjo and Jade, respectively).
Cryptic Conversation: As noted in the summary, the Cackler monologues one of these to himself when confronting Jade in the prologue.
Also most of the "Destiny" interlude, as we have no real idea what's going on there.
Cutting the Knot: During one Physical Feats class, Jade is presented with the task of traversing a Death Trap-ridden obstacle course and ringing a bell. Upon noticing that the course is circular, she just turns around and rings the bell that's a few feet behind her.
HIVE student: Can she do that?
Dark Is Not Evil/Light Is Not Good: Jade's villain persona (a Shadowkhan dressed in black and red) is contrasted with Brother Blood, who wears gold and white (Jinx comments at one point that rather than the traditional light and purity, Blood's colors seem to represent greed and death).
The two adult Jades who appear in the Mind Screwy "Destiny" interlude are a similar contrast. The good (or at least, non-psychotic) Jade is in all black, while the outright villainous Jade wears white.
When Jade regresses into herself in the Master of Games' medallion and meets the Queen, the Queen invokes this in order to convince Jade to merge with her (even bringing up Jackie's dark half released by the Tiger talisman as a comparison).
Raven is recruited for the Tournament of Villainesses, and constantly complains about it (though her demon side does briefly take over).
Dating Catwoman: Gizmo and Mammoth mock Jade after she declares Beast Boy her Arch-Enemy by bringing up how often this trope occurs. Jinx assures her that it's a myth.
Mammoth: You know what they say. First comes aggression, then hatred. Then comes wary respect for skills. Followed by surprising common ground on an issue. Then more hatred and aggression. Then a reboot of mutual respect with one side throwing away a win. Then a romantic rendezvous, and one comes back to the city years later, and a literal custody battle ensues over a wide-eyed bastard.
Gizmo: Would your love child be bluish green, or greenish blue?
The Dreaded: Gadjo has quickly earned this reputation among the other HIVE students — they're all scared stiff of him.
Eldritch Location: There are a couple of these. First, there was that pocked dimension with the twisting, multicolored sky (which caused a Brown Note reaction in Jade, making her nauseous). Then there's the shadow realm of the TT world, with floating islands, some covered in forests and mountains, filled with twisting shadows that seem to switch between a liquid-like and an air-like state.
Enemy Civil War: At the beginning of the story, the HIVE is recovering from one, wherein Blood overthrew the previous Headmistress and ended up having to wipe out the Russian branch of the HIVE.
Enemy Mine: Jinx briefly teams up with the Titans after Mumbo captures both Jade and Starfire and forces them to be his "assistants". Jinx describes it as "sharing a mutual problem", and as soon as Mumbo is defeated she grabs Jade and runs off.
The possible Bad Future glimpsed in the "Destiny" interlude has another apparent example: whatever "Omega" is, it's so bad that the Demon Sorcerers and the Eight Immortals (or a version of them, anyway) team up with each other and Good!Jade to stop Evil!Jade from releasing it.
Jade and Raven teaming up against the Master of Games.
Even Evil Has Loved Ones: Killer Moth dearly loves his daughter, and is distraught when Jade nearly kills her (accidentally) in the Tournament and he swears revenge.
Even Evil Has Standards: From Raven's perspective, Jade, who never actively causes trouble, seeks peaceful alternatives, and doesn't take advantage of Raven being unconscious to hurt her, saying it wouldn't be right.
For a straighter example, when Jade and Blackfire face each other in the tournament, Blackfire is willing to let Jade surrender, as she doesn't want to fight a child. Though when Jade doesn't give up, it doesn't stop her from trying to pummel her.
Also, even the other HIVE villains find the Ax-Crazy Gadjo a bit disturbing.
Even Gadjo has standards, believe it or not, as he thinks fighting is about fighting, not big speeches or special effects, like Susano was doing in the HIVE entrance exam.
Evil Costume Switch: Naturally, Jade is forced to take on a new outfit when she's recruited by the HIVE (and after the above mentioned Clothing Damage, it becomes necessary). She ends up with a mildly complex ensemble composed of a cloak over a robe over a karate gi, selling the fact that she's a magic user who can also fight hand-to-hand.
Evil Laugh: The HIVE actually has a seminar on this, and whether or not it's worth it. Captain Hollywood did this in class once, leading Jade to swear never to do it.
Extreme Omnivore: It seems that as a Shadowkhan, Jade is capable of eating just about anything, in addition to her natural Big Eater tendencies having been increased. In fact, it becomes the subject of a Running Gag via Jinx repeatedly asking if she's part goat or something.
Face Palm: Raven does this after hearing Gadjo's "explanation" for how relationships work.
Fantastic Racism: Much like another story by the same author, there's a lot of subtle (and not so subtle) hate directed towards Metas and other non-humans. This ends up contributing to Jade being pushed towards the HIVE.
Played for laughs when Jade accuses Beast Boy of doing racial profiling after he comments that she and Mumbo have a lot in common (them both being blue-skinned magic users).
Susano appears to hate Jade based solely on him being partially divine and her being part Oni.
Susano also called Gadjo "Gaijin", a word meaning "alien", with great contempt, showing that his racism isn't just towards mystical beings (though since he seems to be in a team with a demon and a ghost, it may partly be because he's a Jerkass and just uses it as an excuse to demean others).
And Gadjo seems to really hate zombies.
Jade lampshades the inconsistency at one point, asking why blue skin was such a big deal while grey skin was fine.
Faux Affably Evil: Brother Blood, who — like in canon — pretends to be a charming old fellow, but really, really isn't.
Within minutes of finding out that the HIVE is a school for villains, she realizes that there has to be a large force of heroes that justifies such a school.
She also realizes that crossing Brother Blood would NOT be a good idea (he's the headmaster of a school for SUPERVILLAINS, after all, and you would have to be dangerous to get a position like that), which is a major part of the reason she hasn't left the HIVE yet.
She also realizes that while failure at the HIVE would not end well, A-listing would probably not be very good either.
At one point, while the Titans are busy with Gadjo, she just goes and gets the thing they were supposed to steal.
She's also pretty much the only one (save Raven to a somewhat lesser degree) who feels that something is up with the Master of Games' tournament (but she still goes along with it, since she wants to return home and hoped the prize would help her).
Girls with Moustaches: When Jade tries to use a potion to try and regrow her eyebrows after a failed spell fried them off, she gets one. When Jinx laughs, Jade throws the potion in her face, causing the bad luck witch to get one nearly reaching her shoulders!
Going to Give It More Energy: Raven does this to defeat Jade in the Tournament — she uses her shields to force Jade to overdose on shadows in the shadow realm, causing her to fall asleep.
Gratuitous Japanese: Jade tends to slip into this when under duress. Presumably, this is due to the influence of her Shadowkhan side, seeing as she herself is Chinese.
Grievous Harm with a Body: When the Titans are watching footage of Gadjo fighting zombies, it mentioned at one point that he's apparently "whaling on zombies with a zombie".
Groin Attack: Jade suggests this to Starfire when they're pummeling Mumbo.
And she does it to the Master of Games later on.
Guile Hero: Jade, just like in canon, is intelligent and cunning, just look at the Cutting the Knot, Genre Savvy, and Summon Bigger Fish tropes on this page. At one point, when Gadjo (who had no plan, only wanting to fight the Titans), is telling them about the way he thinks relationships work, she just goes and steals the artifact.
Hammerspace: Jade mentally lampshades this in regards to Suzano's staff, even using the word hammerspace.
Hero with Bad Publicity: Due to her short temper during her interactions with the Titans and the random Jerk Ass civilians of Jump City, Jade ends up being labeled a public threat. And matters aren't helped any by her having to pretend to be a villain so that the HIVE doesn't kill her.
Insane Troll Logic: Gadjo's "explanation" for how romantic relationship "really" work, which basically boils down to women using sex to force men to take out the garbage so civilization doesn't collapse. When he gives this speech to the Titans, they are all left dumbfounded... except Beast Boy, to whom it somehow makes sense!
Irony: Jade lampshades the irony of her being sent to steal the Jadeite Panda.
Jerkass Has a Point: After the Journey to the Center of the Mind mentioned below, Jade is forced to admit that the Queen has a point or two in regards to how much she's changed (like eating metal and wood, preferring less light, etc.), and decides to step up her game (as she refuses to accept the changes the Queen has in mind, even if she admits to them).
Journey to the Center of the Mind: When Jade is absorbed by the Master of Games' medallion, she ends up inside her mind, where she meets the Queen (her Enemy Within), who tries to present herself as a necessary part of Jade's mind, and tries to convince her to let them fuse together.
Kung-Fu Wizard: Jade. Her villain outfit is to sell the fact that she uses martial arts and magic, and she herself says that between magic, martial arts, and her other abilities (i.e. the Talismans), she'll choose all of the above.
Kryptonite Factor: Beast Boy and Jade argue (in the middle of a fight, mind you) whether or not Jade's Shadowkhan-induced weakness to onions qualifies.
Lame Pun Reaction: At one point Jade makes a bet with Gizmo about what kind of pun the Titans will open the fight with (and she guessed correctly).
Laser-Guided Karma: Jade thinks that gaining the Shadowkhan weakness to onions (and actually experiencing the pain it causes) is this to her for enjoying doing it to Tarakudo. Though she's quick to point out that unlike her, he had it coming.
Leaning on the Fourth Wall: The HIVE has a seminar called F.W.A., which appears to mean "Fourth Wall Awareness". The instructor is completely nuts, and no one takes it seriously — it's just used as a form of hazing for the newer students.
Licking the Blade: Done by the Master of Games with Machete's blade during his fight with Raven.
Loss of Identity: Jade fears that she's becoming less and less like her old self. This only gets worse when she speaks with the Queen, who points out how comfortable she's become with some of the changes she's undergone.
Made of Iron: After accidentally hitting Jinx and her team with a full energy attack during a fight with the Titans only for them to end up only slightly hurt, Jade comments that people in this world are pretty tough.
Subverted and lampshaded with Kitty. Jade gives her a full blast from the Dragon talisman and nearly kills her; afterwards, she comments how most people she'd encountered so far would have walked away from that.
Mind Screw: The interlude chapter "Destiny" features two adult versions of Jade — one evil and one good (apparently) — fighting each other. It borders on being a Bizarro Episode, except it's implied that it actually will be important later on.
Mundane Utility: Jade has used her eye beams to heat up a potion at least once.
Mythology Gag: Jinx says she would never fall for some jerky hero who's always getting in her way. In the show, she did end up in a relationship with Kid Flash after he spent his whole introductionary episode getting in her way and messing with her.
More subtly, the Master of Games abducted Raven, a Dark Is Not Evilheroine, for his "Tournament of Villainesses", like how he summoned Gizmo, a villain, for his "Tournament of Heroes" in canon.
Ominous Message from the Future: After Starfire's trip into the Bad Future depicted in the "How Long Is Forever?" episode, Nightwing sends her back with a letter to the present-day Robin, warning of some unspecified incident involving Jade that caused the Titans (already unstable following Starfire's disappearance) to fall apart completely. While the letter doesn't give details, Nightwing does imply that there's a moral quandary involved, and implores Robin to do the right thing.
Original Flavor: It's been commented on that both Jade and the TT characters are kept very much in character.
Politically Incorrect Villain: Subtle example, but Mumbo does seem to have a tendency to force women into being his "assistants". When he magically places Jinx in a rather revealing outfit, she comments on it being harassment.
Psycho for Hire: Gadjo was apparently a freelance mercenary before even before being recruited by the HIVE. As for the "psycho" part, well, just look at some of the other tropes on this page.
Psychic Block Defense: According to Word of God, Jade, being a higher-level Shadowkhan, has a natural resistance to mental powers that, combined with her willpower and a third factor (that he won't identify), make Blood's Mind Control nearly a No Sell on her.
"Yeah, because you stack the deck. And brag about beating up a girl who has already fought hard while you sit on the sidelines. I know real badasses, and you don't even come close to the list," Zhu Chan taunted.
"Enough of your impudence!" he commanded, firing a starbolt at her. She burst it with an optic blast.
"Sloppy. You may have a lot of power, but you didn't earn it. They may not have been smart, but at least they know their own power, idiot," Jade shook her head.
Red Eyes, Take Warning: At one point, Jade discusses this trope with Beast Boy, and whether or not it necessarily makes someone evil.
Played straight, of course, when Raven's dark side briefly takes out when she's fighting Machete in the Tournament.
Running Gag: There's apparently an offscreen one about Jade's potions exploding.
During the Tournament of Villainesses, Raven reminding people that she isn't a villain.
Also, Jinx has asked Jade multiple times if she's part goat (because of her Extreme Omnivore tendencies).
Screw This, I'm Outta Here: Susano and his team try to corner Jade for a beating at one point, only for Gadjo to show up and curbstomp one of them. The other teammate runs off, and Susano wisely leaves too after a few parting insults.
For a more comedic example, when Jinx and Jade are attending a seminar on minion management, there's a video of Gadjo killing a previous employer for threatening his pies. Around the time he rips off the guy's head and throws it at the camera, the girls decide to ditch out on the rest of the seminar.
Secret Identity: Jade takes on the name Zhu Chan ("Bad Omen") as her villain persona. Notably, this is the only name any character in the Titans universe know her by, even the villains, and most seem to think it's her real one. Meanwhile, the narration switches back and forth on which to refer to her as, depending on the situation.
Jade's conversation with the Queen is based on a similar scene in Kage, another JCA crossover fic.
When Jade is sent into herself in the tournament, her dark side says to be careful not to hit the mirror frame on the way out, a reference to "Through the Looking Glass".
The Queen's goal to be free to act on her desires, but with Jade's cunning is similar to the Jackie Chan Adventures fanfiction Queen of All Oni (by the same author), in which this DOES occur.
Slasher Smile: Due to her now pointy teeth, Jade tends to do this by default. Raven wonders if she's even aware of it.
Spit Take: When told over breakfast that she's being teamed up with Gadjo, Jade spits her miso into Jinx's face. The latter is not amused.
Split Personality Merge: The Queen suggests that this is naturally occurring between her and Jade, due to a combination of Jade's transformation the loss of her Morality Chain (her family), and that the combined being will have her desire to do whatever she wants, but with Jade's cunning (which the Queen herself lacked last time).
Squishy Wizard: Averted. Jade's costume is to sell the fact that she uses magic and martial arts, and she once mentally commented that between martial arts, the Talisman powers, and magic, her first choice will be all of the above.
Stealth Hi/Bye: Jade, naturally, now with the added help of her ability to hide in shadows.
She actually ends up on the receiving end herself a few times, usually from Gadjo and Jinx.
Summon Bigger Fish: When Jade is sent to break Machete out of prison, only for it to turn into a fight with Raven and Starfire, Jade lets Cinderblock out of his cell in order to keep the Titan girls busy.
Tomboy and Girly Girl: Jade and Jinx, respectively. Jade is tomboyish, hating girly stuff, while Jinx is more feminine, and wears dresses (and apparently likes unicorns, according to canon).
Villainous Breakdown: When Raven beats Jade out of his pendant, and during Jade's "The Reason You Suck" Speech to him, Master of Games loses his composure briefly for the only time in the chapter (save his defeat), though he manages to catch himself quickly.
What Happened to the Mouse?: Including the prologue and interlude there's been 9 chapters, and Jackie and the rest of the JCA gang haven't been seen (except in the interlude, where we see El Toro and the Demon Sorcerers along with the Immortals) at all, and have only been mentioned in passing.
Why Did It Have to Be Snakes?: There's an odd variation here, in that Jade was apparently traumatized by the experience the last time she was turned into a monkey, so she's understandably freaked out when it happens again.
Word of God: According to the author, Jade is hightly resistant to Blood's mental control. Firstly, because of her nature as a higher Shadowkhan rendering her resistant to mental powers. Secondly, because of her strong will. The third factor he won't identify.
Worthy Opponent: Gadjo apparently views Jade as one, and she can't decide whether that means he wants to be her friend or if he wants to kill her.
You Exclamation: Jade's reaction to Beast Boy the first time she runs into him after he hit her with an onion.
