Robin: Well, I guess this whole experience proves it really is bad to watch too much TV. Starfire: But truthfully, we only prevailed because Beast Boy watches too much the television. Raven: So, there really isn't a lesson here. Cyborg: Yep, it was all completely meaningless. (Everyone laughs)
Aesop Amnesia: Most of Cyborg's episodes revolve around him accepting, again and again, that he's human, though from different perspectives (not being robotic enough, not being human enough, etc).
Affectionate Gesture to the Head: In "Calling All Titans," Jericho reaches down and pats an exhausted Beast Boy on the head after he climbs all the way to the top of the mountain to give Jericho a communicator.
Ambition Is Evil: Jinx's motivations for villainy stem mostly from her desire to "be somebody". Hey, she was born with "bad luck" powers, so she might as well be a bad person so she can do something great (but terrible) with her life. However, there's also an inverted example of the trope; Jinx is far more ambitious than her lazy slacker teammates, so eventually part of the reason she turns good is so that she can work with competent people like Kid Flash instead of teammates who have no ambitions besides petty theft.
Anti-Hero: Robin. He may be the leader of a team of superheroes, but he even admits to himself that he is too dogged in his pursuit of villains, and is not above lying to his friends if it helps his plan.
Apocalypse How: The Season 4 Finale. Planetary/Total Extinction. The world obviously got better.
And we could technically put the-Larry incited Apocalypse as a Class Z. It's just a filler episode though, so no worries.
Are We There Yet?: Raven to Cyborg, in the T-Car she isn't particularly impressed about.
Arm Cannon: Cyborg's sonic cannons, one built into each arm.
Armor-Piercing Question: Shows up in "Forces of Nature." When Thunder begins to question the morality of what he and Lightning are doing, his brother repeatedly assures him that they're "just having fun." Later, when Slade has tricked them into unleashing a monster, Thunder wants to help the Titans, only for Lightning to start fighting him. Lightning has him pinned on the ground and is ready to kill him when Thunder asks him: "Tell me, brother...are we still having fun?"
Bad Future: Starfire accidentally get sent to one where Cyborg has to stay plugged in at Titans Tower since his batteries are dead, Beast Boy is a fat, bald circus performer, and Raven appears to have gone insane from loneliness. But Robin/Nightwing is relatively fine. He's become just like Batman, a loner with nobody to talk to. Thankfully, Starfire returning to her own time seems to fix it.
Jinx. This trope is subverted with Jinx's Heel-Face Turn in one of the final episodes. If anything it seems that she became bad specifically because she thought she had to follow this trope.
Raven, having demonic powers, defies this trope, even during season 4 by blasting her demonic dad.
Badass Normal: Although Robin's the only member of his team without superpowers, he's also the only one who can take on every member of his own team at the same time. Because like Batman, he had special equipment made to take down each of his teammates. That is why Red X is so hard for the Titans to deal with.
Robin does not like being compared to Slade. At all. (Most noticeable in the Apprentice episodes, he manages to get over it but it's still a sensitive issue for him.) However, this is partially true, since he's as obsessive as Slade. Deep down Robin does realize this, but doesn't want it to be point out. This may be why he's so obsessive with Slade, as he made him something he doesn't want to be and always many steps ahead of Robin.
There's also one episode that's all about Beast Boy's Berserk Button taking physical form (it's a long story) and hunting down a jerk that put Raven in a coma. Surprisingly, the romantic overtones were completely unintentional.
Beware the Nice Ones: Starfire is generally the kindest and most naive of the main characters, but if you hurt her or her friends (or if you just happen to be a villain), she'll really kick your butt. Also helps for her that she is a member of a race whose powers are fueled by emotions.
Beware the Silly Ones: Beast Boy usually plays the role of the plucky comic relief with shades of the butt monkey, but in "Titans Together" he proves himself an incredibly capable leader and powerful fighter. When he meets Terra again after nearly being killed by her and seeing how she's trashed the city, he has no qualms about fighting her even when they were basically an official couple.
In a way, Control Freak also is one. He is an avid television and movie junkie. As Raven called him, "a couch potato with a souped-up remote." At the same time, he can make inanimate objects come to life with said remote, make a larger one that has "high-end equipment to break half the laws of physics", uses said remote to escape into the World of TV, use his television knowledge to Take A Level In Badass and learn how to counter both the Teen Titans and Titans East. Is he a large creepy fanboyish villain? Yes. Is he dangerous? Definately.
Big Entrance: "Birthmark" starts off with Dr. Light fighting the Titans. At first he seems to be holding his own, until Raven makes her entrance. She mimics the last time the two of them encountered each other, with scaling up her size a fair bit, Glowing Eyes of Doom, and tentacles made of shadow.
Raven: Remember me? Dr. Light: (Goes Blue with Shock, turns, and raises hands) I'd like to go to jail now, please.
For those who understand Spanish. At least you know what the bloody hell Más Y Menos are talking about. (No English subtitles are provided.) Their catchphrase, "Más y Menos, sí podemos!' literally means "Plus and Minus, yes we can!" Not only is it a straightforward Spanish rhyme, but it is also a pun on the saying "más o menos" ("more or less.") They're also guilty of Getting Crap Past the Radar, shouting at least one curse word in Spanish! The Latin American Spanish dub had to modify this, naturally.
In one of the fights between Robin and a robot version of Slade, large billboards behind them states "Read the comics" in Chinese.
The Movie has a Japanese bonus. People who don't know Japanese have never been on the internet wouldn't catch the joke when a cute girl calls Beast Boy a geek (otaku) and he thought she called him cute, for example. The Cat Girl keeps talking to him during their fight also, which just frustrates him because he has no idea what she ever says.
Also in one scene, one of the signs spells out "Robin" in Katakana.
Bit Part Bad Guys: Mumbo, Control Freak, and Dr. Light started out like this before moving up to better things. Same can't be said for that poor giant scorpion Terra crushed during her Batman Cold Open.
Beast Boy: Hey, check it out! (flash-freezes The Brain)Brain freeze! *Everyone else groans*
Brainwashed: Happens to all the Titans (main, East, and a few reserves) at least once. Beast Boy seems to get it a lot after the team's first run-in with Mad Mod. In "Revolution," also featuring Mad Mod, the entire population of Jump City.
This was Brother Blood's greatest power, and the fact that it didn't work on Cyborg was the reason for his obsession with the boy.
Breaking the Fourth Wall: "Larry" counts. While he is just Batmite, or Robinmite rather, his fifth dimensional tricks break the fourth wall just fine. He's from beyond it, after all.
Brick Joke: In season 1 "Nevermore", Dr. Light causes Raven to lose control to her dark side, growing in height and using shadow tentacles to drag him under her cloak. By the time he's uncovered, he's pale and shaking, muttering about the darkness. In season 4 "Birthmark", the Titans fight Dr. Light again. Raven appears with the same height and shadow tentacles. Dr. Light immediately goes pale and says meekly "I'd like to go to jail now."
Bring It: Robin does this to the H.I.V.E. trio in "Final Exams".
The episode "Troq", is an Anvilicious message about racism. Sadly, it's somewhat undermined because the episode involves them committing genocide against a robotic race, on the word of a known racist. Sure they almost caused some severe Collateral Damage, but you could make an argument that they're trying to protect their species at all costs.
Lampshaded at the end of "Episode 257-494"
Robin: Well, I guess this whole experience proves it really is bad to watch too much TV.
Starfire: But truthfully, we only prevailed because Beast Boy watches too much the television.
The series' version of Gizmo was also adapted into the Comics, as the son of the Dwarfish original.
Cain and Abel: Starfire and Blackfire, who still look like a parallel of Queens Elizabeth and Mary Tudor, even though Glen Murakami admits that they watered down the much more intense rivalry of the original comics into a more kid-friendly, "I Dream of Jeannie/Bewitched kind of way." If you're even slightly familiar with the comics, you'll know what he's talking about◊.
Calling the Old Man Out: Raven did this to her demonic dad in the season 4 finale. While blasting him to oblivion, too.
Raven: Fathers are kind! Fathers protect you! Fathers raise you! I was protected by the monks of Azarath. I was raised by my friends! They are my family. This is my home. And you are not welcome here!
Calling Your Attacks: Cyborg and Beast Boy (and Robin, when it happened) had a habit of nicknaming their teamup moves. In "The Quest", Robin has someone else call his attacks for him.
Captain Obvious: About every time the alarm goes off, one of them says "trouble". Really? I never would have guessed.
Captive Date: Killer Moth threatens the city with destruction unless Robin takes Killer Moth's Bratty Teenage Daughter, Kitten, to the prom. Robin complies, much to his chagrin.
Card-Carrying Villain: Several. Few villains even got origin stories, so most seemed to just be causing havoc for the fun of it.
Cardboard Prison: Usually they do not even bother mentioning an escape. Recurring villains who where caught and jailed simply reappear in later episodes, regardless of how ineffectual or silly they are.
Cerebus Syndrome: Though the show as a whole was more of a Rollercoaster, the individual arcs tend to show this one strongly (except the season four arc, which apart from a brief cold open with Dr. Light, is pretty bleak throughout). The Terra arc in particular is a great example, with plot progression that basically goes: Yay, the Titans have a new friend! Okay, she clearly has trust issues and suffers Power Incontinence when she uses too much power, but hey, none of the team are perfect. Aww, she and Beast Boy are clearly crushing on each other, too. Wait, she works for Slade!? And thanks to her he knows everybody's weaknesses? And now they're taking over the city together? And wow Slade's a Bad Boss. But Terra makes a Heroic Sacrifice and saves the day, and she's apparently frozen in stone forever. Bittersweet Ending, much?
Clap Your Hands If You Believe: Inverted. Recently-deceased villain Slade has returned to beat the living crap out of Robin... or so Robin thinks. Turns out he'd been exposed to a drug that makes him see Slade, and his body to react as if struck. He is able to disbelieve in his opponent just in time to save himself from the killing blow.
Clingy Costume: Terra's final costume was an armored suit that Slade had fused with her nervous system. With Clothing Damage, it's clear that she wears bandages where the suit's parts don't go — an aversion of Stripperific, which without the bandages is what the suit would be.
In "Birthmark", Slade rips off over 85% of Raven's outfit while mind raping her... or perhaps the OTHER kind. Watch closely, her top is being held on by thin shoulder straps. There's absolutely no back.
Rule 34: A surprisingly high quality animation by ZONE-sama does exactly that. And with minimal changes to the original episode's audio track, disturbingly enough.
Terra's outfit in "Aftershock Part 2"; see above.
Robin's outfit got quite a bit torn up in "Haunted" when he was fighting with what he thought was Slade.
Beast Boy's suit near the end of "The Beast Within" gets pretty ripped up... Which raises a lot of questions about how it got ripped up, or where it goes when he changes...
Cold Open: Nearly every episode features a scene before the opening theme.
Color-Coded Characters: Each of the characters who had some form of energy manipulation powers had a distinct color associated with them, observable when they used their powers and also when their eyes glowed. The major ones:
Black with white edges for Raven (red edges for her Superpowered Evil Side and pure white for her "White Raven" form)
In the episode Nevermore, the various parts of her psyche wear different colored robes to match that aspect. Pink is happy, gray is timid, and green is brave.
Green for Starfire
Yellow for Terra
Bright red for Brother Blood
Fiery red-orange for Trigon (and Slade when empowered by Trigon)
Dark purple for Blackfire
Pale pinkish-purple for Jinx
Collapsing Lair: Slade gets this twice in the first two season finales, Brother Blood gets it twice in the third, and the movie starts off with an attack on Titans Tower.
"Deathstroke the Terminator" is simply Slade here.
Averted with Raven, as that is her real name.
Elasti-Girl inverted this with Beast Boy, calling him by his real name once- "Garfield." No one else does this, even after this event.
Starfire is a downplayed version- while her real name is unknown (The comics have it as "Kori'andr", but it's also turned into "Kori Anders" again in the comics), she says that it translates to "Star Fire," so they're sort of calling her by her real name... a little...
Conservation of Ninjutsu: If the Titans are facing a single villain for the episode, they'll most likely be taken down easily. A lone titan tends to have to be capable of quite a lot (i.e. Robin taking down Cinderblock).
Continuity Nod: Also, Dr. Light's instant surrender when he came face to face with Raven, as he recalled the Mook Horror Show she'd subjected him to before. Guess he was still scared of the dark...
Another is in Can I Keep Him where one of the "foods" Starfire offers to Silky is mustard, which she was drinking in The Sum of His Parts.
In "Go!", the bus Cyborg catches from Starfire looks very much like the one he stopped in "Final Exams".
In "The End" Part II, Starfire mentions that she's used Raven's powers once before (in "Switched" when she and Raven switched bodies).
Convection Schmonvection: In "The End", Badass Normals Robin and Slade run around on rocks floating in lava. Later, Cyborg's face is held about a few inches above a lava lake and he's totally fine. Even if his mechanical parts are very heat resistant, the human parts should burn.
Composite Character: Robin is Dick Grayson and has his acrobatic origins, relationship with Starfire and status as Teen Titans leader, Jason Todd's temper and prone to lowering himself to criminal level when he has to, and Tim Drake's Bo Staff skills and Batman-like tendencies.
Cranium Chase: During an episode, Starfire's head and body are separated when Larry messes with reality. She then has to chase it down.
Crazy Cultural Comparison: Starfire has a few strange Tamaranian customs, such as The Pudding Of Sadness and The Poem of Gratitude. Also, Zorka berries which cause mutations in certain organisms, like say Silkies.
This is forgivable, however, seeing as how she had just betrayed him and his dearest friends to their worst enemy after they took her in twice and welcomed her into their group with almost no qualms whatsoever (Raven being the one voice of dissent, which quickly stopped as she came to trust Terra as well)...and for some reason, she still expected him to be OK with that. The only one to blame in that situation was Terra herself.
Dance Battler: Jinx will sometimes look like she's dancing or doing some complex gymnastics while dodging attacks in battle.
Dark Action Girl: Jinx fits this trope to a T (heh heh heh). She's also the leader of the H.I.V.E F.I.V.E, all male, and the only one with ambition. Her Heel-Face Turn was partly triggered by high ranking villains initially dismissing her as useless. She has yet to do real heroics, her motivations seem to be simple revenge (and a crush on Kid Flash). Of course, the phrase "Dark Action Girl" really brings Raven to mind... though she's more an example of another trope.
Dark Is Not Evil: Many thought Raven will make a great villain because of her very dark past. She isn't. In the case of Jinx, she IS a villain at first, but her relationship with Kid Flash convinced her to do a Heel-Face Turn.
You are dark, and darkness is often misunderstood. —Malchior
Darker and Edgier: Season 4: Trigon's Plot is TO FORCE RAVEN TO FULFILL HER DESTINY AS THE ANTICHRIST AND DESTROY THE WORLD! Birthmark alone has a scene where Slade brands Raven in a scene that is uncomfortably creepy. This after the series was sometimes accused of being too kiddie.
Haunted, definitely. It's basically Robin having a PTSD-fueled mental breakdown the whole time, and the final scene sounds as much like rape as Birthmark does.
Raven is a lonely girl with father-angst that develops a close friendship with a sunny and perky girl. Even their powers are foils; Starfire uses her powers through fully embracing her emotions while Raven has to suppress her to keep them under control.
When Raven pulled Dr. Light into some sort of dark vortex within her cloak, and when he came out he was curled up in the fetal position muttering, "S-so dark. Make it stop. Please make it stop."
The episode "Haunted" also ranks up there as one of the creepiest pieces of Western Animation targeted towards kids. They took Slade, a villain who's already creepy in his own right, and left the audience constantly unsure whether he was Back from the Dead and torturing Robin, or whether Robin had gone insane and was mutilating himself. The truth is somewhere in between.
Disney Dog Fight Between Killer Moth and Starfire. The "Dog" in question can't make up his mind so he explodes
The Ditz: Starfire, though she's just naive and unfamiliar with her new environment as opposed to being legitimately stupid. She's demonstrated her intelligence on more than one occasion. She knows exactly how many moles there are in a Kilogram of Oxygen and has explained mathematically (off-screen anyway) how it is possible to travel faster than the speed of light.
Do-Anything Robot: Gizmo's tiny mechanical backpack holds a freaking car in it. Cyborg might qualify as well.
The episode "The Beast Within" seems to resemble a PSA about steroid abuse, especially in the scenes with Beast Boy going into an animalistic rage in the gym. However it has nothing to do with steroids whatsoever.
"Troq" has this brief discussion about Val-Yor's racism against Starfire's kind:
Starfire: You know what it is like to be judged simply by the way you look? Cyborg: Of course I do. I'm part robot.
Dramatic Drop: Terra drops the T-communicator when Robin announces her big secret: that she can't control her powers. She thinks Beast Boy lied to her and told, but Robin once worked for the world's greatest detective and figured it all out on his own, unaware it was a secret.
Emotionless Girl: Invoked by Raven, who has emotions, but is forced to keep them in check by the nature of her powers. ("Fear Itself" provides a pretty good example of what happens when her emotions become too much for her to handle.)
As confirmed by Word of God, this is a trait Slade has. His inability to comprehend Robin's loyalty towards his team and the lengths he would go to keep his friends safe and his not considering any residual loyalties Terra had towards the Titans led to his defeat twice.
Robin in "Apprentice", though he did not do a Face-Heel Turn like his teammates thought he would.
Terra in Aftershock, who wears nothing but a breast plate and underwear, with the rest of her body covered in bandages.
Evil Counterpart: Blackfire. And later, Red-X served as sort of a 'morally ambiguous' counterpart to Robin. Jinx was designed to be a sort of evil counterpart to Raven, both magic users with a "dark" colour theme.
Because PINK is the new black!
Slade acts like a sort of Evil Counterpart to Batman (as he was intended to be in the original comics, complete with Wintergreen, his own Anti-Alfred). So it's no wonder he and Robin are so similar, since Robin takes after his mentor.
Exposition Cut: Probably not the only example of this in the series, but used in the episode "The Beast Within" after the team found Raven in the maw of a feral Beast Boy.
Starfire: Rest. You are safe. He can no longer harm you.
Raven: He didn't hurt me, he saved me.
Starfire: From what? (cue scene transition)
Expository Theme Tune: Not in the traditional sense, but whether the opening credits are the English or the Japanese version of the theme song will let you know if it's a serious or silly episode, respectively.
Robin's mask basically emotes as if it were his eyes, and he never takes it off (except once in the movie, and then he was wearing sunglasses).
Slade's mask also counts, even if there's only one eye.
Red X actually counts, too; in "Revved Up", his reaction to landing on the bus only to discover Raven and Starfire in it is nothing short of hilarious.
Expy: Professor Chang bears a striking resemblance to Hannibal Chew, of Blade Runner: From his distinctive clothing and facial appearance, right down to the frigid environment in which he works. Chang's voice actor? None other than James Hong, who also played the role of Chu.
Starfire is probably one of the most prominent examples. As an alien, she is happy to eat and prepare many Tamaranean delicacies, which disgust the rest of the crew, and has several strange eating habits when it comes to Earth food (such as consuming mustard as a beverage).
Starfire: I suggest a large pizza with pickles, bananas, and mint frosting.
Thanks to a virus, Cyborg goes on a rampage through the town and eats several normally inedible objects in "Crash", such as a stop sign and a little girl's teddy bear.
In "Final Exam", after Jinx, Gizmo, and Mammoth take over Titans Tower, Mammoth is shown consuming the blue, moldy food in the Tower's Fridge.
The Faceless: Slade. Even when his mask gets knocked off in "The End" and his undead face is just a skull. Though at that point in the show, he had been reanimated by Trigon, but not resurrected. Apparently, this means he can't regrow his skin.
The episode Forces Of Nature has Slade disguised as an old man, though this functions as a bit of a Mythology Gag, as his disguise is somewhat similar to his original comics appearance.
Red X fits this as well, considering we only ever see his mask.
And, to a lesser extent, Robin, due to the fact that his eyes are never shown, but this would fit better into The Eyeless trope.
False Innocence Trick: Raven befriends a knight hero in a book by the name of Malchior. He tells her stories of how an evil dragon trapped him there. He teaches her powerful magic and things seem awesome, until she sets Malchior free, only to find out "Malchior" is the name of the evil dragon, not the knight.
Family of Choice: The Titans support each other in all the good ways of a family, but they're also a family in all the worst ways with all the conflicts. Their family-like relationships are used to look deeper into each of the character's back stories and character flaws.
Fandom Specific Plot: There are many fanfics where Terra being a local school girl in one episode is explained. Usually it is that Terra had amnesia after being frozen in lava and started going to school in the city. There is always a Raven/Beast Boy/Terra love triangle. Another extremely common plot is to put them in a High School AU.
Which is odd since the show was almost explicit that Terra was choosing to forget.
Fantastic Racist: Val Yor. Now we know that "Troq" is the intergalactic equivalent of the N-word, used to describe Tamaraneans. Lampshaded by Cyborg:
Starfire: You know how it feels to be judged just because of how you look?
Cyborg: Of course I do... I'm part robot.
Fastball Special: Multiple variants. Of particular note is the "Beast Boy Blitz", where Beast Boy turns into an armadillo and rolls into a ball so that Cyborg can throw him. And then turns into a rhino mid-flight.
Female Gaze: The camera does tend to focus on Robin's butt an awful lot…
The Fifties: The Fifties Fifties version, in a Show Within a Show which Beast Boy lands in for a short while before an eight-foot robot smashes into the suburban paradise home like some demented manifestation of Chandler's Law.
Final Solution: Our heroes go on a trip with Val-Yor and commit genocide on a race of allegedly hostile robots.
fic that resurrects Terra after her Heroic Sacrifice are almost as endemic are those that inflict Die for Our Ship on her. After she actually was resurrected, or something, it changed into fixing what the author didn't like about it. One of them, part of the "Sanza Salazar trilogy", has Terra revived by the actions of a group of villains instead of whatever mysterious circumstance revived her in the original series, mostly so the Titans can get to her before she decides I Just Want to Be Normal like she did originally.
Quite a few fix "Things Change" where Beast Boy is able to successfully convince her to come back to the team.
The HIVE kids were initially a competent villain team and the collective Evil Counterparts of the Titans, sliding into infighting and immaturity only when not "working". Later seasons flanderized them into being all incompetents (except for Jinx) who only won because they got lucky.
Their boss, Brother Blood, was in his first appearance a cool-headed, charismatic leader who only overacted when playing to an audience; later appearances made him a straight Large Ham.
Notably, the Titans themselves and Big Bad Slade inverted this trope; in the first few appearances they were defined by one or two traits (i.e. Robin was serious, Raven was a goth, Beast Boy was an immature jokester, Slade was a Card-Carrying Villain, etc.), but later appearances added a lot more depth to all of them.
Follow the Leader: Try to find an American kids' action cartoon made in the past few years that does not take any cues from this series' success. It's not easy. Teen Titans solidified the trend of Animesque action-comedy kids' shows that run on Rule of Cool.
Forced to Watch: Robin has been subject to this at least twice, and Raven once.
Forgot About His Powers Well, her powers at least. Raven has so many one-off powers she magically forgets about that it get's silly.
For the Evulz: In the first season, Slade's apparent goal is to destroy the city for no reason at all. Subverted in the finale, the destruction of the city turned out to be a diversion and his true goal was to blackmail Robin into becoming his apprentice.
Trigon was easily the most powerful villain of all, seeing as how he destroyed the world approximately 12 seconds after entering our dimension. However, being the "incarnation of evil" doesn't seem to leave much room for a complex or interesting personality. Luckily, every episode with Trigon in it also had Slade around acting as The Dragon.
Most of the villains in the show seemed to be wreaking havoc just 'cuz. Though it doesn't help that the show had a general aversion to origin stories.
Genius Ditz: Starfire may come off as ditzy, but she knows a lot of things, like the secret to travelling faster than the speed of light and knowing the exact number of atoms in a kilogram of oxygen.
Genre Savvy: Control Freak and Beast Boy. Cyborg also has his moments.
Genre-Busting: It's a superhero action cartoon whose animation is often more inspired by Tex Avery or the weirder side ofAnime than anything in U.S. Comic Books, yet often has very dark, dramatic storylines and, on a few occasions, will have an episode focus almost entirely on character interactions, with the obligatory supervillain battle relegated to a minor B-plot.
Gilligan Cut: In "Fear Itself" when no one looks impressed with the horror movie Beast Boy is touting...until they start it.
God Guise: In one episode, Raven crash-lands on a planet inhabited by tiny aliens, and is worshiped as a God simply for being more than three inches tall.
God Save Us from the Queen!: Clearly, Blackfire did not have the best interests of her people in mind when she took over the planet. Fortunately, in their culture, a monarch's rule can be taken away from her via Trial by Combat, which is exactly what Starfire did.
However, although the early episodes portray Raven as straight-up Goth, her personality begins fluctuating later and she is revealed to be more calculating, introverted and antisocial than generically Goth.
Except for Season 5, where all but three episodes (the origin story episode, the Go Karting with Bowser episode, and the final episode) are in some way connected to the fight against the Brotherhood of Evil. And even the final episode mentions how the Titans have just come back from defeating them.
Half-Human Hybrid: Raven is half-demon. A case could be made for Cyborg as a half-robot.
In "Snowblind: Red Star. A supercharged supersoldier from Russia, he willingly locked himself up in a old power plant for years to keep from hurting other people due to his body discharging radiation every few hours and at the end of the episode has Starfire take him into the stratosphere when he goes supernova due to an overload from battle. He returns in the second-to-last episode with no particular explanation.
Robin nearly pulls one of these in the Season 1 finale by blasting himself with the same deadly nanites that were killing the rest of the Titans, gambling on Slade being more willing to let them all live than to let Robin die. He was right, too.
His Own Worst Enemy: Raven is her worst enemy by far. Even her dad, who was the ultimate personification of evil pales in comparison (he was beaten easily after Raven resolved part of her inner conflict). In fact her stoic personality is her way of controlling her dark side.
Hostile Show Takeover: The theme sone of the episode Lightspeed is interupted by the H.I.V.E Five, who claim that the show is theirs now. The Teen Titans don't appear anywhere in the episode, except for Kid Flash. The Teen Titans are back by the next episode though.
Hotter and Sexier: Notably averted and a source of some criticism from those hoping for a more direct adaptation of the comic book. The character designs for the Titans were made more awkward and teen-like than their Comic Book counterparts. Although this can be said for virtually all the characters, Starfire is the obvious poster child for this particular aversion.
How About A Smile: When Killer Moth's daughter Kitten forces Robin to take her to prom in exchange for Killer Moth not releasing his mutant moths, she tries to force him to look like he's enjoying himself.
Human Outside, Alien Inside: Pops up for Starfire from time to time, such things as her allergy to metallic-chromium and strange recipes. Also when she attempts to "bathe" her pet, Silky, by licking it like a mother cat. With a two-foot-long tongue. Apparently, she also has nine stomachs. And let's not get started on her transformation....
Humorless Aliens: Starfire has some trouble understanding why, exactly, Beast Boy's jokes are supposed to be funny. When exposed to "Why are ducks so funny? Because they're always quacking jokes!", she said something like, "Oh, I get it! It is humorous because ducks lack the large brains necessary for the telling of jokes!"
Beast Boy: It's your life Terra, your choice, it's never too late to change.
The show's finale
Terra:Things change, Beast Boy. The girl you want me to be is just a memory.... you're the Teen Titan. That's who you are. That's not me. I'm not a hero. I'm not out to save the world. I'm just a girl with a geometry test next period and I haven't studied.
Robin: You know, Robins, the mask makes me feel cool, too.
It Came from the Fridge: "Final Exam". Later played with, as Mammoth has absolutely no problem scarfing the entire fridge.
I Was Just Passing Through: Completely averted by Red X. In "X", Red X tracks Robin down to Professor Chang's lair Just in Time to snatch Robin out of mid-air before Robin can fall into Chang's disintegrator cannon. When Robin comments on this, Red X doesn't try to claim that he acted for his own reasons.
(after Red X saves Robin's life)Robin: I thought you didn't like to play the hero. Red X: Doesn't mean I don't know how.
Jobber: Dr Light ends most of his appearances in short order as the unfortunate target of Raven's Superpowered Evil Side. After getting one episode where he actually was a threat in season 5, the Grand Finale ended with his attempted bank robbery being responded to by the entire extended Titans team.
Knight of Cerebus: If Slade or Trigon is in an episode, it's pretty much a guarantee it won't be humorous (except for the first few Season One eps with Slade, but even then he wasn't played for laughs, though he also wasn't as creepy as he'd become later on). Also, Terra. You wouldn't think it at first but once all her deep emotional issues and comatose conscience come to light, you get the impression she's not there for fun and games...especially in her second appearance where she tries and succeeds in killing each of the Titans. Apparently anyway.
The Puppet King, villain of the episode Switched, was extremely creepy and tried to destroy the Teen Titans' souls while keeping their bodies as his slaves.
Kuudere: Raven — although occasionally someone manages to push Raven over into using the more aggressive Tsundere tactics.
In the Trapped in TV Land episode "Don't Touch That Dial" Cyborg recognizes the episode of the show they're in as being episode 1 of the fourth season. Feel free to guess what episode and season "Don't Touch That Dial" is.
The same episode (also known as "Episode 257-494", its production number) also has Robin grabbing the camera, declaring that watching television while Control Freak was inside will liquefy your brain. For added comedic value, the show they were interrupting during the scene featured a doctor who had discovered the secret to world peace and was going to share it with the viewers.
It also has a mugshot of Control Freak on a news bulletin, with him holding up a number: 257-325—the production number of "Fear Itself", Control Freak's first appearance.
And to really nail down the ways this episode mutilates the fourth wall, it even goes after the in-show version of it - at the very end of the episode, Cyborg and the red-clad woman from the soap-opera scene are hugging.
Leeroy Jenkins: The Doom Patrol partially due to Mento's Good Is Dumb and Knight Templar tendencies. Robot Man manages to be a particularly egregious example on his own though, getting taken down over two episodes than any of the Titans over the entire course of the series. Even lampshaded by Raven: "You sure he has a brain in there?" Suffice it to say, he'd be a lot worse if he wasn't literally Made of Iron.
Left the Background Music On: In the episode where Mad Mod tries to put all the Titans in detention, an Ear Worm-y song is played during their attempted escape. Right before the "exit" is discovered, Robin turns a switch on a bust of Mad Mod, ending the song.
Lethal Chef: Raven's pancakes — burned like charcoal on the outside, still runny on the inside. Starfire may be a perfectly competent cook by Tamaranian standards but... well, it's called pudding of sadness and is produced by someone who treats mustard as a beverage...
Starfire: Wonderful!! I shall go cultivate the fungus!
Marshmallow Heaven: In "Forces of Nature", Starfire hugs Beast Boy (as a cat) after forgiving him for the motor oil balloon prank, but if you look carefully, Beastie is rubbing his face ON HER BOOBS. Hey, he's a teenage boy, what did you expect?
Happens to none other than RAVEN, after getting back into their bodies at the end of switched Starfire hugs Raven and for split second we can see her head at... a questionable place
Martial Arts Do Not Work That Way: Season 1 Robin being the most frequent offender; fortunately he does clean up his act, and his fights that don't invoke this trope more than make up for the ones that do.
The Mean Brit: Mad Mod, who's mean, but also wacky and entertaining — and appears to be motivated by a need to correct young people's education and grammar.... And also has an aversion to America in general; hence Jump City's makeover in "Revolution" to look more like a mish-mash of English cities.
Which might beg the question, why not show defiance by trying to embody Scotland?
In a similar vein, Cyborg's cover identity when he infiltrates the HIVE Academy: Stone. This is more of a nod towards Cyborg's real name Victor Stone. The fake power more likely came about because of the name, not the other way around.
Monster of the Week: The Titans have a couple of villains who are Monster of the Week (Besides of the ones where the Brotherhood of Evil reunites them). Some villains were lucky to have two appearances.
Mood Whiplash: The show basically had three kinds of episodes: dark and serious ones with occasional comedy, largely serious plotlines but with plenty of wacky hijinks on the side, and completely insane goofy ones. Apart from the multiparters (which were pretty much all the first type) all bets were off as to what the next episode would be like, and it wasn't at all uncommon for something serious to be followed up immediately by something bizarre (or vice-versa).
Raven(In regard to the latter): "Cool! I-I mean, oops."
"The Sum of His Parts" goes back and forth between two storylines. The main one features Cyborg being held prisoner by Fixit, who wants to remove his human parts and turn him into a full robot, and almost having his memories erased in a scene that could rival "Birthmark" for Mind Rape factor. The subplot features the rest of the Titans in their efforts to catch Mumbo Jumbo, who they think is responsible for Cyborg's disappearance, in a chase scene over-the-top with silliness and visual gags.
"Birthmark" starts out with the Titans battling Dr. Light. They joke about his incompetence, and go out for doughnuts, all except for Raven. And then, in a remote location, Slade bursts out of the ground after two seasons of being dead.It gets worse.
More Dakka: Cyborg when Slade's army starts marching to Titan's Tower (The End (Part 1)). Arm cannons? Try two giant arm cannons, MMM-grade missile launchers in the chest and shoulders, a giant cannon on his shoulder, and draining the Tower's power to feed it all. Of course, Slade is left standing, his army rises out of the ground, and Cyborg is completely drained afterwards.
A very unfunny version. In the episode "Haunted", Robin accidentally inhales an unnamed hallucinogen from an old mask of Slade's. Unlike most examples, however, this Mushroom Samba leads to one of the darkest episode of the series - Robin hallucinates that Slade is everywhere and goes on a rampage trying to stop him, even going so far as physically hurting Starfire (his best friend and love interest) and threatening to "take down" his team if they try restraining him. The drug manifests every blow on his body as though he really is battling someone, and so before he realizes that bright light disperses the visions, he's nearly beaten to death... by himself.
Cyborg gets his turn in "Crash", when Beast Boy accidentally gives him a computer virus. He runs around crazily and eats everything in sight, while having strange food-related hallucinations.
In one episode Red X, an alter-ego Robin used, returns, and it's definitely not Robin. On BB's board-o'-theories, a careful viewer can notice "Jason Todd" and Nightwing.
Larry's real name: "Nosyarg Kcid" in "Fractured", Beast Boy being referred to as a "changeling" in Winner Take All. (The first Robin's real name backwards and the name Beast Boy used upon joining the Titans in the comics, respectively.)
When Cyborg infiltrates HIVE, he uses the alias "Stone"; in the comics, his civilian identity is Victor Stone.
In the same episode, Beast Boy shuts up Robot!Cyborg by turning into a starfish and clamping over his face, in a manner very reminiscent of classic DC villain Starro the Conqueror.
A lot of the lines from Terra's episodes are slightly changed from The Judas Contract, such as Terra referring to Raven as a "witch" (she referred to her as that a lot in the comics). Terra being turned to stone and the monologue is also very reminiscent of Terra's burial statue and the monologue during her death.
Beast Boy's infinite movie and T.V. show knowledge. Possibly a reference to the fact that he was at one point a television actor in the comics.
In "Mother Mae-Eye", the titular villain character combs Robin's hair in the style that the original Dick Grayson version of the character wore (y'know, the one without pants), which he eventually shakes out
His hair also slips into this for a few seconds in "Date With Destiny". He's very quick to shake it out.
When Beast Boy dresses up in Robin's costume, he jumps through a screen held by Starfire that proclaims him "The Sensational Character Find of 1965". This is an homage to the title page of Robin's first-ever appearance in Detective Comics, and the date of Beast Boy's first appearance (Robin himself was "The Sensational Character Find of 1940").
In the "The End, Part 1", Beast Boy finds a penny, with the date of 1964 which he then gives to Raven for "good luck". The Teen Titans debuted in The Brave and the Bold #54 (July, 1964).
Right before Robin and Starfire have their Big Damn Kiss in the movie, she tells him to "Stop talking". It's rather minor, but Starfire said variations of this frequently to Dick Grayson in the comics.
Negated Moment of Awesome: During the Titans' first meeting with Hive, after the other four Titans are eliminated from the fight, Robin simply motions for them to Bring It...and then all three attack at once and send him plummeting into the sewers.
Never Say "Die": Played completely straight, even the reason why Slade went by his civilian name rather than his codename in the comics: Deathstroke. The most egregious example would have to be in the season 2 finale where just about every variation of death and kill is used but the actual words: Destroy, annihilate, exterminate, eliminate etc.
Nice Job Breaking It, Hero: Terra could have probably been persuaded from Slade's influence earlier if it wasn't for the fact that Beast Boy pushes her off the edge when he declines her friendship at the very end of "Betrayal". Way to go, hero.
Nice Job Fixing It, Villain: Thanks to Terra going ridiculously overboard in trying to destroy the Titans and the city, and generally prove herself a villain, the Titans manage to put aside any past feelings toward her and kick her butt easily the next time she confronts them by herself. And then Slade does some fixing of his own when he decides to be an asshole to Terra and take physical control of her through her supersuit, which is a big factor in Terra's final Heel-Face Turn.
New Powers as the Plot Demands: Raven. There are possible justifications for it, such as just using new spells or perhaps being afraid to go all out due to her demon nature.
No Sell: Occurs semi-regularly, but a notable example is in "Wavelength" when Cyborg hits Brother Blood with a (small) missile and there isn't even any Clothing Damage when the smoke clears.
But that's nothing compared to "The End: Part One": While trying to stop Slade and his army of fire demons from entering the Tower and taking Raven, Cyborg plugs into the Tower's power supply and unleashes a pair of gigantic shoulder cannons whose payload is implied to be somewhere in the vicinty of a suitcase nuke. When the dust clears, Slade just cracks his neck back into place while the fire demons promptly regenerate.
Not Just A Tournament: In "Winner Take All", a number of teen superbeings are teleported to an unknown location, where the Master of Games invites them to take part in a Tournament of Heroes that will determine which of them is the greatest young hero on Earth. What the competitors don't know is that when they lose, they're trapped within the Master's jewel so he can use their powers.
Not so Above It All: Raven dressing up in Robin's uniform in "The Quest" after Starfire, Beast Boy, and Cyborg urge her to do so.
Raven: You know, Robins, I've gotta admit, the mask makes me feel (Luminescent Blush) ...cool.
Demonstrated terrifyingly effectively in the season 4 finale, when Slade and Robin fight off an army of Trigon's lava monsters, using the exact same moves. As Robin points out though, there is one major fundamental difference between them:
Not-So-Imaginary Friend: Bobby, the giant teddy bear that Melvin created. "Created" as in Melvin's power is to make things she imagines real.
Not This One, That One: In "Betrothed", Starfire returned to her home planet for her Arranged Marriage. When her sister announced Starfire's husband-to-be, a beautiful Tamaranean boy showed up and Starfire was actually looking forward the idea of being his wife. The boy then revealed a hideous-looking alien as the actual husband-to-be, much to Starfire's horror.
Beast Boy. Not only he knows his sci-fi knowledge, he's a manga worshipper. Curiously, despite being one, BB doesn't actually seem to know what it means.
And Control Freak. Can't forget him.
Starfire technically counts in the Titans in Tokyo movie where she quickly mastered playing a combination Guitar Hero/DDR/Whack-a-Mole arcade game, where she gets the attention and praise of everybody in the arcade.
While Starfire's skirt is magic, there have been episodes where the camera is nice enough to give the viewer a view up her skirt in a "blink and you'll miss moment". Sometimes that area is the same color as her skin...
Same goes for Elasti-Girl and Kole. Like Starfire, they were the same color
Pardon My Klingon: Starfire occasionally spouts odd Tamaranian curse words and insults.
Pietŕ Plagiarism: Raven holding an injured Robin in "Birthmark". Added irony for being caused by Trigon and that they are in a church. He returns the favour a bit later once Slade is done with her.
Plot-Induced Stupidity: Raven has a very diverse set of magical powers...that she mainly uses to throw things at people. There's also Cyborg's seldom used detachable limbs and grappling hook hand. Not to mention he can turn his hands into like any tool he can think of.
In the episode "Kole" the entire Titans team ends up falling through a huge hole into a prehistoric world. Despite Beast Boy being able to turn into flying animals, Cyborg's above mentioned grapple hook and Robin owning every swinging rope gadget imaginable. Starfire and Raven on the other hand somehow completely forget they can fly.
Starfire's forgetfulness is particularly bad. One minute she's lifting tons over her head and flying faster than light, and the next she's struggling against badass normals. Justified because her powers are affected by her emotional state.
Robin: Do NOT separate! I repeat! DO NOT SEPARATE! Robin, as heard on the ship's communication:(static) separate! I repeat! (static) SEPARATE! Starfire: As you wish. (The ship separates. Cue the Titans being stranded on an alien planet.)
Race Lift: A possible case for Jinx. In the comics she was Indian (and bald); on the show she's chalk-pale, but most likely Caucasian. However, the comics Jinx had a completely different set of powers concerned with elemental control. There was another Jinx with luck-based powers, but that one was male, in a spandex bodysuit which covered the head.
Slade: No, Robin. I won't stop. Not now, not ever. I am the thing that keeps you up at night. The evil that haunts every dark corner of your mind. I will not rest, and neither will you... I'm very real. Could you have gotten all of those bruises from someone who wasn't there?
It's even worse in Birthmark. Slade rips off a considerable portion of Raven's outfit. He then grabs her by the arms. While she moans in agony. Holy crap.
Mad Mod turned the sky into a huge Union Jack... somehow. To say nothing of all the other unexplained weirdness that happens whenever he shows up. Though Mad Mod is probably more a Master of Illusion than a Reality Warper.
Remembered I Could Fly: Seemingly played straight when Beast Boy wants a moped and Robin reminds him he doesn't need one, because he can fly. Then averted when Beast Boy says he already knew that, but complains that his arms get tired.
Then justified in one chase scene where it's shown that of all the fliers in the group, he's the slowest and weakest. While the others all have modes of transportation (Robin has his motorcycle or being carried by Starfire, Raven can fly, and Cyborg has the T-Car), his animal forms rely on his stamina.... which depending on which animal form he picks, can vary wildly. It even goes into Shown Their Work territory when he does become a cheetah... but quickly runs out of steam, just like in real life.
Revenge Fic: Dakari King Mykan is infamous for only writing that kind of fanfiction in general. Most of which center around him turning the Titans into jerkasses who hurt or kill their friends, because he is unhappy with the fact certain pairings got bombed (to the point that the finale literally gave him PTSD). Thankfully he sucks so much, people who write MSTingsof his work told him to grow up and do worse to the characters than what he thinks is evil.
There's also The End of Ends which is this towards the finale of Teen Titans and doing almost exactly what the above described, with the added bonus of blowing up entire worlds just because one pairing came through while his preferred paring sank.
Also Season 4's mainly dead end way of preoccupying the remaining three protagonists while Robin can play the hero and Slade can set up his anti-villain/hero moment. Additionally a pretty effective way of providing tidbits of backstory and moonlights from one particular previous season.
Shaped Like What It Sells: The balcony of the pizzeria is shaped like a slice of pizza when seen from above. The floor is the cheese and the tables are the pepperoni.
Robin in "Stranded", leading to Starfire being so upset that she is unable to use her powers. He chalks it up to her not understanding what a girlfriend is. She demonstrates that she understands perfectly. They had ridden a Ferris Wheel together as she ate cotton candy (season 1), and she called him "my boy" in the boyfriend sense while angry in "Date With Destiny" (2x06), which was promptly followed by a slowdance after the two were declared King and Queen of Prom. Robin also has several Save the Princess moments in "Betrothed" (3x03), including scaling the side of a massive castle to get to Star. "Stranded" is in Season 4. No wonder Starfire considered them to be in a sort of relationship.
Averted in "Date with Destiny", when Robin yells at Cyborg that Kitten is not his girlfriend. Averted in that Robin did not like Kitten in any way, shape, or form.
Ship Tease: TONS of it between Robin and Starfire before they "officially" got together in The Movie.
Most of "Lightspeed".
Shonen Hair: Robin, probably to invoke an "anime" look more than anything.
Raven when her demonic side first surfaced during the Dr. Light fight in "Nevermore".
Terra also cracked a few of these during "Aftershock Part 1".
Sliding Scale of Silliness Versus Seriousness: The whole show dances a jig up and down this. Take, for example, season three, where you've got an episode that's basically one of the most brutal, drawn out mind rapes ever put to Western Animation, very close in production order to an absurd story about Cyborg accidentally downloading a virus and trying to eat every inanimate object in sight.
One-shot villain Fang, who has a spider for a head!
Spinoff Babies: A similar case to X-Men: Evolution: the original comicbook began with a team of teenagers, but most of the team members in the TV series first appeared as adults.
Squishy Wizard: Raven is not nearly as squishy as she could be, seeing as she has at least some martial arts moves, but she's still the most vulnerable to direct physical attack of anyone on the team, and if her spellcasting is interrupted the effect will usually fizzle (or worse, go haywire).
Step into the Blinding Fight: For Robin in an episode he went on a quest and one of the trials was to fight a blind snake in his own element, a dark cave with zero light. He eventually has to learn to try and stop seeing his enemy and start hearing and feeling where the master is.
Steven Ulysses Perhero: Slade's name is a pretty interesting case. His comic-book name, Deathstroke the Terminator is rejected by the bigwigs at Cartoon Network because saying death is a big no-no and the fact that "Terminator" is still copyright from Governor Arnie. As a result, the producers picked his actual name, Slade Wilson. And the weirdest thing is that it works. Deathstroke sounds like a hitman's name, which works in the original comics because he's a mercenary.
Still Wearing The Old Colors: Beast Boy still wears the outfit of his old group. He ditches the mask after Raven calls it Goofy, but that's about it.
Supposedly Robin is still wearing the uniform from his "old Job".
Stolen Good, Returned Better: The Hive takes over the Titans' (filthy) Tower. By the time the Titans retake it, the Hive have cleaned it up and alphabetized their CDs. The Titans are appalled, since now they can't find anything and they were saving that blue mold. But they did find the remote!
Super Hero Origin: Oddly, not featured until the fourth-to-last episode of the series.
Super Strength: Cyborg. Starfire beats him in this department, though.
Superpower Lottery: Raven, Brother Blood, and Slade while working for Trigon all seem to develop five or six new abilities in every alternate scene. Their typical powers are also pretty damn out-there. It's probably a sign when quite a few of Raven's episodes ("Switched", "Fear Itself", "Bunny Raven", "The End") feature her losing her powers in some way. And of course, her teleport-through-shadows power is only remembered when it suits the plot; if the Teen Titans need to be impeding in escaping a situation, the teleportation ability won't even come up.
Jinx's powers seem to let her do anything as long as its considered "bad luck" for the target, anything. This can be as simple as causing small explosions or electronic mishaps, to telekinetically dismantling the chair they are sitting on, to causing the ground itself to break apart so water mains can just so happen to burst out right into the person's face. Her powers definitely made her stand out among her comrades, who were just a Super Strong Guy and a Techno Wizard.
Surprise Creepy: "Fear Itself". It starts off very light-hearted with Control Freak, one of the goofiest, least threatening villains the series has...and then becomes a horror story about Raven not admitting her fear, causing monsters to run amuck the Tower.
Surrounded by Idiots: In the episode "Lightspeed", Jinx remarks "I don't know why I hang around with you nitwits." By the end of the episode, she's done hanging around with those nitwits.
Swarm of Rats: Occurs as Starfire's "demise" in the episode "Fear Itself".
Swiss Army Hero: Beast Boy. Well, he can be whatever (Animal) you need him to be.
Swiss-Army Weapon: Robin with his discs and Speedy with his arrows. See-More's eye can change into many different kinds of weapons or tools, from a heat laser to bludgeoning projectiles, to x-ray vision and even a blimp... unclear if See-more is more of a case of a weapon or a body part though.
Cyborg's arm can cycle through sonic cannon, blowtorch, and pretty much an entire toolbox.
The Chew Toy: I'll give you a hint, he has pointy ears and green skin like an Orc or a Goblin, eats tofu, is a (Not very good) jokester, and is the official Plucky Comic Relief of the entire series.
Terrible Trio: The HIVE kids. Jinx is the leader, with Gizmo and Mammoth working with her. They're pretty dangerous on their own if they put their minds to it, but generally need a higher-up to scare them into that level of competence — Slade in their first appearance and BrotherBlood later. Ultimately they strike out on their own, but without a Man Behind the Man they become joke villains. And then Jinx finally gets fed up with that and does a Heel-Face Turn.
Theme Tune: "When there's trouble you know who to call, TEEN TITANS! From their tower they can see it all...!" Cyborg sang his own variation at one point. ("When there's trouble you know what to dooooooooooooooo! CALL CYBORG! He can shoot a rocket from his shooooooooooooe! 'CAUSE HE'S CYBORG! Dodadadodo, somethin' like that! Nananana, BIG FLUFFY CAT! That's right!")
The tune was also used as a cue. If Puffy Ami Yumi sing in Japanese, you're getting one of the wacky, goofy episodes. If they sing in English, it's a more serious episode. The only exception to this rule was the first Raven-centric episode, "Nevermore".
In the Movie, not only is a translated to Japanese and back to English version sung by Beast Boy during a Karaoke scene, but also in the credits of said Movie, each of the five main characters sing (or in Raven's case, deadpans in a way that you KNOW she must be trying to look away from everyone) at least two lines.
There Are No Therapists: One wonders how society is okay with a group of teenagers with no parental figures involving themselves in horrific violence every day without any support, except from each other. Also, each Titan has an extremely dark past which quite obviously still affects them and even interferes with their work sometimes, yet they don't try to seek help in any way, and in the case of most of them, simply try to bottle it all up.
Thinking Up Portals: Herald, despite being Slade's son, helps Beast Boy and the other surviving Titans in "Titans Together". He can open up a portals with his trumpet, which he then carries them in a Pocket Dimension while he innocently slips by the Brain's perimeters. He's so harmless looking that the villains just think he's a random person walking through the area. During the ensuing battle, he also randomly helps others out by opening portals for others to jump through or redirect attacks.
Token Minority: The Teen Titans avert this. We have Robin the white guy, Cyborg the black guy, Starfire the orange alien, Raven the gray demonic hybrid, and green Beast Boy. Considering that they have a habit of meeting minority villains and allies, this show averts this trope pretty well.
In the original comics, this is reversed. Starfire's Proud Warrior Race is played up a lot more, with her constantly wanting to hang out with the boys and solve everything through violence. Raven, on the other hand, is The Empath, and is a demure pacifist who cries during nearly every single fight.
Dr. Light, of all people, takes one in "Kole", by virtue of having a better plan than usual, and having veryloose limits on what can be done with "light-based" powers. He loses the level with his inevitable defeat by episode's end, however.
Control Freak takes a level in TV badass (not that it makes him any less dorky in the script) in Don't Touch That Dial, and tops it off with "I Know Karate".
Totally Radical: Beast Boy, Cyborg, and especially Gizmo were the worst offenders.
Town Girls: Starfire is the sweet, naive, girly one (femme), Raven is the level-headed bookworm (neither), and Terra is the tomboyish new girl (butch).
The Ugly Guy's Hot Daughter: Raven to Trigon and Kitten to Killer Moth. They're both powerful evil monstrous beings (Trigon being a large red demon and Killer Moth being an actual large moth), while their daughters are both pretty.
Ugly Guy, Hot Wife: Trigon and Arella, Raven's parents. He's a huge red demon with multiple eyes; while Arella is a beautiful young woman. Kitten and her boyfriend Fang fit also. She's a pretty blonde, with a nasty attitude to boot; while Fang is a human/spider mutant, but he only wants to develop his relationship more with Kitten.
Unexplained Recovery: The show uses this a few times to varying degrees. The most blatant example is the second season finale, "Aftershock", where Terra hunts down and seemingly kills all five Titans. Her methods range from No One Could Survive That deaths to smashing Robin with a boulder at point-blank range, at which point it immediately cuts to her kicking his crest across the floor to Slade, implying that yes, there was even a body, and she pulled it off. And then they all show up underground looking little the worse for wear and ready for round two.
Also, whether the schoolgirl was really Terra in the series finale, and if so, how she lost her memory...or if she really did lose it at all. This is explored somewhat more in an issue of Teen Titans Go!
Also, anytime Slade's mask gets knocked off something happens to make sure we don't see his face (in Apprentice II he managed to cover it with his hand before more than a silhouette could be seen, and in The End II his face was just an undead skull).
In Final Exam, we only hear the final sentence of Robin and Starfire's conversation as they enter the living room:
Starfire: ...and that is the secret to traveling faster than light!
Raven's backstory gets one is "Switched" when she and Starfire have to know about each other's powers.
Raven: I was born in a place called Azarath...
In Haunted, it's revealed that the chemical reagent in Slade's mask that caused Robin's hallucinations didn't activate itself; someone had to have triggered it from outside the tower. We never find out who is behind this.
In Trouble in Tokyo, when Robin needs to ditch his superhero persona because he was framed for a crime, you think you will finally see his eyes, but nope, now he's got big 'ol shades.
Actually, we DO get to see his eyes for a second, when Robin and Star's moment gets interrupted by the rest of the team. Of course, they're only specks because the animation goes haywire, but still.
Red X's identity and how he knew about the suit in the first place.
One of the New Teen Titans shorts lampshades the Wild Mass Guessing on the subject of his identity, and the majority consensus as well. That, Red X is Jason Todd.
Unusual Euphemism: Gizmo works in these like other people work in oils or clay. What the hairball?!
Starfire:(putting a flower on Robin's lapel) I believe on such occasions, it is customary to wear a dead plant?
Vague Age: It goes with the series lack of showing anything of the heroes personal lives.
Values Dissonance: In-universe example. In "Betrothed", Robin is appalled by the idea of Starfire having an arranged marriage, but Raven responds by asking if the Titans have any right to question Tamaranian culture. The issue's rendered moot anyway, since it turns out Starfire was lied to and she didn't have to marry anyone at all. Besides, Robin was complaining for other reasons.
Kitten demands that Robin take her to the prom, or she'll unleash mutant insects on the city. Robin is not happy. Neither is Starfire.
Blackfire also flirts heavily with Robin in her debut appearance; however, this seems to be more about making Starfire angry than an indication of real interest on her part, as she doesn't even interact with Robin at all when she shows up again.
Voices Are Mental: In "Switched", when Raven and Starfire switch bodies, they still have their original voices.
"Fractured" featured some Mind Screwy variant where Beast Boy, Raven and Cyborg briefly spoke in Raven, Cyborg and Starfire's voices, respectively, after snatching the other party's mouths off their faces.
Waif-Fu: Starfire may be cute and beautiful, but she packs super-strength. She even beat Cyborg in terms of sheer strength, showing she was capable of lifting at least FOUR TIMES the weight Cyborg was struggling with, and with ONE ARM.
Wasn't That Fun?: One episode has Raven forced to take three little kids who are potential superheroes to a safe place to stop them from being kidnapped by the Brotherhood of Evil. At one point, she and the kids are trying to escape from Monsieur Mallah by riding in a cable-car, and the wire snaps. They go plummeting down the mountain in the car, which eventually crashes, but the kids land harmlessly in the snow. The two who can talk both promptly sit up and scream, "Again! Again!" Raven's reply? "NO AGAIN."
Wave Motion Gun: In The End: Part 1. As a last resort, Cyborg hooks himself up to the Tower's electricity supply and proceeds to arm a truckload of hidden equipment. This culminates in double blasts from two massive sonic cannons, spiriting several hundred fire demons back to Hell. Probably bumped up the episode's HSQ considerably.
In "Go" it turns out that the Gordanians also have this on their ship.
Robin: (to Starfire) You fight me, you kiss me, but you never stop to mention they have a giant particle weapon!?
What Happened to the Mouse?: At the end of the Trapped in TV Land episode Cyborg has brought a soap opera star back to reality with him. What happens to her is never explained. Then again, how she got there is never explained, either...
In Season 5, what happened to the Doom Patrol in the finale? Their leader was shown to be obsessed with taking down the Brain, you'd think they'd know when the Brain made a move as big as capturing the Titans en masse and they'd do something about it.
Pay close attention to Slade's butler in the pilot, for he is never seen again. (He does make a brief appearance in the comic as a victim of Ravager, but his relationship to Slade is never elaborated on.)
He does exist and have a backstory in the main comics, though- his name is Wintergreen, and he's a relatively minor character. He appeared with the rest of the villains in "Titans Together".
Wondergirl appears on the Wheel in Titans Together, but never appears in the episode (either speaking or not). Due to contract problems, Wonder Woman and her supporting cast isn't allowed to appear in shows she isn't a main character of. No Wonder Woman, no Wonder Girl. This doesn't apply to comics, and they somehow sorted this problem out by the time Young Justice came around.
World Limited to the Plot: With a couple episodes being exceptions, used with full force until Season 5. A good example of this is that despite Robin, Aqualad, Speedy, and Kid Flash being characters, we never even hear the names of their adult counterparts. We also never hear Robin's name, though it's implied a couple of times to be Dick Grayson.
Wrench Wench: Raven, of all people, though its easy to miss. Terra has this aesthetic, but isn't.
Yank the Dog's Chain: Terra's now an official Teen Titan, made friends with her teammates and even had a little romance with Beast Boy. You thought she's going to be a permanant character, right? WRONG. As it turns out, after the debut appearance, she seeks Slade's help, and even give out vital information to him into order for Slade to send his robot minions to attack Titans Tower. For once, we should have actually believed Raven's instincts.
You Didn't Ask: The True Master when Robin asks why she didn't say who she really was.
You Wouldn't Like Me When I'm Angry: Raven is easily the most powerful Titan, but makes it clear that she has to avoid strong emotions or risk losing control of her powers. She proves this by administering a couple good Curb Stomp Battles through the series (see Dr. Light in "Nevermore" and Slade in "Prophecy") when sufficiently angered. Typically this terrifies the crap out of everybody, including herself.
A Continuity Nod in the beginning of "Birthmark" illustrates just how scary Raven was from "Nevermore". Just watch Dr. Light's reaction to seeing Raven for ostensibly only the second time here @ 1:30. She must be pretty scary....
Beast Boy, of all people, is the runner-up in sheer scariness. In "Betrayal", he gets serious and nearly kills Slade while protecting Terra, relenting only after Slade Mind Screws them both. Then there's "The Beast Within," where mystery chemicals and fits of anger turn him into a ridiculously fast and powerful man-beast, showing what can happen when he stops being the Plucky Comic Relief and how much damage he's really capable of doing. In season four's finale, he even manages this transformation willingly. In "Things Change", he beats the living daylights out of Slade for suggesting that Terra wants to forget her past. Of course, it turns out to be Actually a Doombot, but considering the damage taken by Slade...
Starfire is another example, as seen in the episode "Go!". After escaping her captors and fleeing to Earth, she goes on a berserker rampage, nearly destroying the entire city (didn't help there was a language barrier with herself and everyone else at the time). The other four Titans were barely able to stop her, and that was when she STILL had on her ridiculously heavy handcuffs meant to keep her subdued. Just imagine how much damage she could have done if they weren't on. Starfire only stopped when Robin offered to get the cuffs off.
All of the Titans have this to some degree, if they get the right Berserk Button pushed.
Your Mind Makes It Real: "Haunted", when Robin is haunted by hallucinations of Slade, Raven enters his mind and tries to calm him down by showing there is no one there - only for the hallucination to strike again and leaving Raven with a sore jaw.. And "Fear Itself", though in this case, it's just Raven's mind for everyone.
