Students
The Detective Club
In General
- Adults Are Useless: The main reason the club has to exist in the first place
- Four-Temperament Ensemble: Colton and Maps are Sanguine, Olive is melancholic, Kyle is phlegmatic, and Pomeline is choleric.
- Freudian Trio: Olive and Pomeline are the superegos, Maps is the id, and Kyle and Colton are the egos.
- Delinquent: All but Kyle frequently disregard the rules. Colton and Olive in particular
- Hidden Depths: Maps might be weird and not usually that bright but she is great with puzzles, Colton is lazy and cocky but very clever, Pomeline isn't as much of the Alpha Bitch as she seems, and Olive is aloof, bored, and the school loner—but also very smart and nicer than she seems
- Kid Detective: All of them are teenagers
- Paranormal Investigation: Their cases frequently revolve around this
- Ragtag Bunch of Misfits: Pomeline seems to be more interested in cults than making friends, Colton is a fireworks-dealer, Maps is the Cloudcuckoolander, and Olive is considered the school freak.
Olive Silverlock
- All of the Other Reindeer: Considered a freak by most of the school.
- Ambiguously Brown: We don't know what her ancestry is, but she appears to be a dark-skinned albino of some kind. Her mother has a much lighter skin tone and blond hair in a picture before turning albino later on while her dad seems to be completely absent, leaving Olive's origins in the dark.
- Amnesiac Hero: Doesn't remember the most recent summer
- Berserk Button: People saying her mom was crazy. Batman and his cohorts also tend to set her off.
- Brilliant, but Lazy: Tutored Heathcliff and is mentioned to have had great grades, but where the story starts she's just gotten so jaded that she doesn't try anymore; rarely paying attention in class and allowing her grades to slide. It is justified, though.
- Butt-Monkey: Often made fun of by the the others and seems to be the one given the worst jobs—if only because she doesn't care enough to argue it.
- The Cynic: Her defining characteristic. You will rarely find a single positive word in any of her lines. Given what she's been through, it's hard to blame her. Apparently, she wasn't always like this, as commentary from the other characters indicated that she was "normal" the year before.Olive: Trouble. This is my life.
- Delinquent: She just doesn't care anymore. She casually skips class and rarely pays attention in class. That said, she's not a horrible student, just apathetic, as she managed to be a tutor to Heathcliff.
- Disappeared Dad: Issue 12 reveals Olive's mother killed her father as Calamity and told Olive he died in a car accident.
- Famed In-Story: Rumors are constantly being spread about her, very few of them flattering.
- Four-Temperament Ensemble: The melancholiac—cynical, focused, depressed, and intelligent.
- Freudian Excuse: Her apathy and occasional jerkiness are excused by how freaking awful her life has been
- Freudian Trio: The superego
- The Hero: As the main character
- I Just Want to Have Friends: Her hidden desire that comes true around the sixth issue when the Detective Club is started.
- It's Personal: The reason she first agreed to join the Detective Club
- Jerk with a Heart of Gold: She's not really a jerk, but her aloofness and depressed "don't-care" attitude lead others to ostracize her and call her "creepshow". However, she's shown a surprising amount of empathy to others who are willing to spend time with her, even risking her life on several occasions for those she cares about.
- Loners Are Freaks: Hit with this trope repeatedly to the point that she openly distances herself from the few people she can call friends.
- Loner-Turned-Friend: To the Detective Club and mainly Maps
- Momma's Girl: She associates with her mother far more than her father (who is never directly mentioned) and she blatantly narrates the fact at the end of the second issue.Olive: After all, I am my mother's daughter.
- We later learn this is because Olive never knew her father because Calamity killed him, presumably while Olive was too young to remember him.
- Only Sane Man: Sees herself as being this in the Detective Club—and she arguably is until Kyle joins, being more logical and grounded than Pomeline, Maps, and Colton.
- Playing with Fire: Implied to have this power in the flashback where she's surrounded by flames.
- Red Eyes, Take Warning: She normally has reddish eyes but they really become disturbing when she's surrounded by fire.
- Red Oni, Blue Oni: The Blue Oni (cynical and melancholic) to Map's Red.
- Secret Legacy: It turns out she's not just the daughter of a pyrokinetic super villain, she's from a long line of pyrokinetic supervillains.
- The Spock: Along with Pomeline. To Maps' The McCoy and Colton's The Kirk.
- The Stoic: Rarely shows emotion.
- Steven Ulysses Perhero: Gee, I wonder what her hair color is?
- Superpowered Evil Side: Calamity seems to be this for the whole Silverlock family.
- Took a Level in Kindness: Becomes much nicer and more open as the series goes on and she starts to get over her trust issues.
- Troubled, but Cute: Seems to be Kyle's opinion of her.
- What the Hell, Hero?:
- Gives one to Pomeline for reading her mom's posthumous letter.
- Ends up on the receiving end of one from Maps for calling the cops on Riko near the end of the Robin War tie-in issue. Maps accused her of doing it because of her Batman hating.
- White-Haired Pretty Girl: It's even in her name.
- You Leave Him Alone!: To Batman when he tries to detain Killer Croc. She sets the entire building on fire with fireworks to make her point.
Mia "Maps" Mizoguchi
See Robin
Pomeline Fritch
- Action Girl: Handy with a crossbow and magical lore.
- Alpha Bitch: One of the cool kids and absolutely hates Olive at first. She gets better with time, even helping Olive on several occasions.
- Brutal Honesty: Has a habit of confronting people, especially Olive, about the thing they would rather not talk about.
- Character Development: Starts out loathing Olive, but later on becomes one of her closest associates (not that she'll admit it). This is best seen when she offers to do an entire project for her after Olive's ordeal with Killer Croc and Batman, when in previous issues she wouldn't give her the time of day.
- Cute Witch: More of a Wannabe, but she has extensive knowledge of all things occult. Like a younger, gender flipped John Constantine.
- Cult: Revealed to be part of a bat-themed cult called the Order of the Bat along with Heathcliff in the third issue.
- Embarrassing Mother: After a failed magic act.
- Four-Temperament Ensemble: The choleric.
- Freudian Trio: The superego
- Goth Girls Know Magic: She has a mildly gothic style, and some magical talent.
- Lovable Alpha Bitch: Becomes one of the heroes after her Character Development, but still keeps her Alpha Bitch traits.
- The Spock: Along with Olive. To Colton's The Kirk and Maps' The McCoy
- Vitriolic Best Buds: Even after they start to become friends Olive and Pom still have a hard time getting along.
Colton Rivera
- Ambiguously Gay: Harbors a secret crush on someone. Many fans suspect that it's towards Kyle, given that he often acts nervous around him. In #12, Colton outright remarks on Kyle's good looks in his absence, and when the latter is in dire need of rescue, Colton performs a Diving Save, which the artist gives loving attention to.Colton: We've got a handsome tennis star to save.
- In the Annual, Pom pretty much calls him out for having a crush on Kyle, made all the more evident when he proceeds to insist Kyle help him catch a campus poisoner. While they're on the case, Kyle nearly figures out what Pom meant before being distracted by a clue.
- He fesses up in issue #3 of Second Semester. To Pom, of course, not Kyle.
- Brilliant, but Lazy: Able to break into anywhere and good at puzzles yet he's also pretty bored and unmotivated.
- Delinquent: Even worse than Olive with his fireworks smuggling and regular defiance of school rules.
- Cool Shades: Wears them everywhere and it's eventually revealed that it's mainly to hide black eyes, given to him by his abusive father.
- Four-Temperament Ensemble: Sanguine
- Freudian Trio: The ego
- It Amused Me: His motivation for almost everything he does.
- The Kirk: To Olive and Pomeline's The Spock and Maps' The McCoy
- The Sneaky Guy: His role on the team
- Stuff Blowing Up: He's a fireworks dealer.
Kyle Mizoguchi
- The Ace: Good-looking and popular with good grades. He's also an excellent tennis player along with being Olive's ex-boyfriend, but he still looks out for her, though.
- Big Brother Instinct: When Olive wants to take a break in their relationship, the only thing Kyle asks is for Olive not to break Maps's heart.
- Charles Atlas Superpower: Not the worst example. He's on the tennis team, but he's apparently strong enough to bust open an iron gate that had a chained metal lock on it with brute force alone.
- Even the Guys Want Him: Specifically Colton.
- Four-Temperament Ensemble: The phlegmatic
- Freudian Trio: The ego
- The Kirk: To Olive and Pomeline's The Spock and Maps' The McCoy.
- Nice Guy: One of the few people to be genuinely nice to Olive, but she always pushes him away due to her own personal issues.
- Oblivious to Love: Just barely failed to infer that Colton likes him.
- Shonen Hair: Cloud level spiky.
- Sixth Ranger: He's the last addition to the team and its least constant member.
Other Students
Lucy
- Jerkass: She doesn't get along with Olive anymore (apparently they were much nicer to each other before the summer break) to the point that she won't even talk to her, just hand her notes. She's also whiny and a crybaby but refuses to acknowledge Olive's showings of concern for her.
- Put on a Bus: At the end of the first story arc, her parents send her to a different private school — specifically, one without ghosts.
Heathcliff
- Book Dumb: Implied since he needed Olive as a tutor.
- Cult: Revealed to be part of some kind of bat-themed cult called the Order of the Bat at the end of the third issue.
- Put on a Bus: Left school to become a roadie for Black Canary's band.
Eric Jorgensen
- Hopeless Suitor: He has a huge crush on Maps, who sees him as nothing other than an occasional friend (he's beyond delighted when she gifts him a homemade action figure of himself), especially since he's unable to tell her how he feels due to his nervousness, jittery behavior and loner nature.
- Nervous Wreck: Jumps at the slightest provocation and is always jittery and afraid.
-
Reclusive Artist: A pretty good one from what little we've seen of him, but he always runs away in terror whenever someone comes to look at it.
Tristan Grey
- Freakiness Shame: Ashamed of his condition, but Olive is quite accommodating as a result of her own social difficulties.
- Half-Human Hybrid: Spliced with a bat gene as a result of the Langstrom Virus (Man-Bat).
- Red Eyes, Take Warning: Subverted. He has them as a result of the virus, but is ultimately a pretty good guy at heart.
- Rescue Romance: Seems to have something of a fling with Olive as a result of him saving her life during the summer. His closeness to Olive leads to jealousy from Kyle which turns into antagonism once Kyle stumbles upon Tristan transforming in the science room.
- Sixth Ranger: An occasional one for the main group.
Katherine Karlo
- Alliterative Name: Katherine Karlo
- Expy: Of Annie from Batman: The Animated Series with a bit of Crona.
- Extreme Doormat: For her father, Clayface.
- Loners Are Freaks
- Shrinking Violet
- Sixth Ranger: Becomes one for the group eventually, helping them out on occasion. It's especially noticeable in that she eventually sticks everywhere Maps goes, as Katherine uses a part of herself to become Maps's hair dec flower. This leads to Katherine saving Pomeline and Colton from Professor Scarlet, as Maps had given them her things just in case.
Amy (Spoilers)
- Alliterative Name: Amity Arkham
- The Corrupter: Has this attitude towards Olive.
- Delinquent: Much more straightforward example than Olive.
- Enemy Within: For Olive.
- Evil Counterpart: Seems to be one for Maps. They're both tomboys, they both like Olive to the point of Ship Tease, they both are interested in mysteries of the Academy. But where Maps is a friend to everyone and simply loves mysteries, Amy is an outright bully and believes Academy secrets will lead her to some sort of treasure. Where Maps just simply wants to be friends with Olive, Amy seems interested in making Olive as bad as herself.
- Expy: Of Tyler Durden.
- Jerkass: Makes Olive break professor Macpherson's window, cuts on old portrait, bullies Eric, steals his maps and inhaler and locks him and Olive in the attic, just because she can.
- Punk
- The Reveal: Amy isn't real, she exists only in Olive's mind, and is in turn possible a manifestation of the vengeful spirit of Amity Arkham.
- Shadow Archetype: In many ways, she is like Olive with positive traits removed and negative ones maxed out. Fitting, since she exists only in Olive's head.
- Superpowered Evil Side: For Olive.
Faculty
Headmaster Collingwood Hammer
- Badass Teacher: Although he's a jerk, he does care about the general well-being of his students and his school and will kick the ass out of anyone who dares try to endanger them. Just ask Scarecrow and the Joker-Venom fueled zombies.
- Jerk with a Heart of Gold: Pretty deep down, but he does care about his students enough to dish out corporal punishment to anyone who tries to hurt them on school grounds.
- In-Series Nickname: Hammerhead by Maps. He's particularly annoyed by it and tells her to refer to him as headmaster.
- One-Man Army: Easily fends off an entire horde of Joker-Venom fueled zombies before hoisting them up in a net while his students discuss Joker stories.
- Reasonable Authority Figure: While he's maintained a reputation that ensures his students don't consider him to be so the reader is able to see that he's actually quite reasonable. For instance he definitely knows Colton stole his beloved car and while he's furious about it he doesn't call the authorities and tries to give Colton a chance to anonymously return the thing. Unfortunately unbeknownst to him the car fell into a sinkhole. With this in mind his decision to expel Colton after he's caught stealing again, in combination with all of the other trouble Colton has gotten into, looks far less unreasonable.
- Sadist Teacher: Enjoys watching students squirm and has a particular bone to pick with the Waynes for an unexplained reason.
- Stern Teacher: When he's not the above, he's this. He expects the rules to be followed to the letter and won't tolerate deviation.
Prof. Isla Macpherson
- Adults Are Useless: One of the only teachers to avert this thus far. She's the only one of Olive's teachers to notice her issues and actually try to counsel her compared to the rest of the apathetic faculty. Her knowledge of Gotham's history and the mythology that surrounded it proved helpful in Damian and Maps' investigation. She's also aware of Tristan's condition and keeps it a secret while helping Langstrom treat him. Eventually she has realized that Olive and her friends get into all sorts of shenanigans, but trusts them to be smart and mature enough to solve things themselves and to ask for help if needed. She also directly keeps in touch with Batman.
- Big Friendly Dog: Has one named Ham who appears to be a Doberman.
- Cool Teacher: Pretty much the only teacher the students actually like, and...
- Hot Teacher: The prettiest teacher Olive has and reasonably endowed as well.
- Random Smoking Scene: Seen smoking without any prior hints to her habit (granted she's a teacher) on the athletics field, where Olive is coincidentally watching Kyle and moping. She's never seen smoking again after this.Macpherson: [sees Damian and Maps holding hands] I should snap a wee photae!
- Ship Tease: Implied to have had a one-night stand with Bruce Wayne.
Prof. A.S Scarlet
- Bookworm: Loves literature to the point of being able to recite entire soliloquies and poems off the top of his head. He's also the head of the drama department.
- Face–Heel Turn: He goes from a kind teacher to rather gleefully trying to kill Pomeline and Colton in order to take the book of Amity Arkham that they had found, so nobody would know he had obtained it.
- Large Ham: When in acting mode, he surprises Olive by reciting the lines of the first apparition from Macbeth.
- Mythology Gag: The below could also be a reference to the fact that Professor Scarlet was an alias for a villain of the week named Bookworm from the 1960s Batman show.
- Palette Swap: Seriously, he looks like a blond haired Riddler wearing brown instead of green minus a question mark. Damian even lampshades it.Damian: These children are right to rebel against the teaching of useless drivel, Scarlet. If that's even your real name.
Dr. Kirk Langstrom
- Adults Are Useless: Langstrom is far from useless, and the kids trust him, but he does tend to get pulled into their plans without considering their safety and might be a little too good at keeping secrets. Maps gleefully leads a "zomibe" to him and he goes right along with the kids musing on just what the Talon's nature might be.
- Berserk Button: Anything that risks the possibility of having Tristan's condition go public as he knows the potential ramifications.Langstrom: [examining an injured Tristan] This is bad. Children, go find Professor Macpherson and tell her what happened.Maps: But wouldn't the nurse be more helpful?Langstrom: [suddenly angry] Do as I tell you!
- Fatherly Scientist: A kind doctor and deeply regretful for Tristan's condition which came as a result of his creation.
- Labcoat of Science and Medicine: He's a doctor and Gotham Academy's new science (unspecified, but most likely biology or biochemistry) teacher.
Prof. Hugo Strange (Spoilers)
- Bald of Evil: Naturally.
- Batman Gambit: Most, if not all, of his Evil Plan hinged on Olive disregarding his advice on sitting out of adventures regarding the truth about her mom and Calamity.
- Evil All Along: He's the reason why Calamity has been showing up even after Sybil Silverlock passed away and tried goading Olive to become Calamity to learn about the things that Sybil refused to tell him regarding the entity. Olive wasn't amused.
- Evil Plan: Knowing more about Olive and her mother than anyone else, he disguised himself as Calamity and caused the fire in the Academy's theater, kidnapped Kyle, and left Olive and the Detective Club with a key to Arkham Asylum, just to get Olive to become Calamity and reveal the secrets that Sybil never told him.
- Four Eyes, Zero Soul: Wears glasses and seeks to manipulate a teenager into becoming a city-destroying supervillain.
- What Happened to the Mouse?: Disappeared when Olive's friends caught up with her.
- Walking Spoiler: Just about anyone who has cursory knowledge of Batman's rogues gallery would be able to guess that Hugo Strange has ulterior motives.
Prof. Achilles Milo
- Eviloutionary Biologist: Transforms Coach Humphreys into a werewolf, and took Tristan Grey's blood and used it to create an army of Man-Bats.
- Mad Scientist
Coach Humphreys
- Our Werewolves Are Different: Was infected with lycanthropy by Prof. Milo. Although he is seeking a cure now with the help of Dr. Langstrom.
Prof. Derek Warren
- Canon Character All Along: Warren is not his last name. His real name is Derek Powers, aka Blight, the Arch-Enemy of Terry McGinnis, the Batman of his era. His goal was to travel through time and kill Terry's father to undo his birth.
- Cool Versus Awesome: A radiation-powered skeleton from the future vs a vampire.
- Evil Gloating: Would probably achieve his plan, if he just killed Warren instead of ranting why he wants to do it in the first place.
- Evil Versus Evil: Definitely a bad guy, but ends up wrestling with a vampire.
- Grandfather Paradox: More or less points out his plan would result in this, but is willing to try anyway.
- Hair-Trigger Temper: It's easy to get him mad.
- Hidden Depths: A sociopathic Corrupt Corporate Executive normally, but in his guise as "Professor Warren" he proves quite competent as a science teacher (likely owing to his situation). Of course, this might just speak to how good he is at deceiving people than anything.
- I Just Want to Be Normal: Resents his condition and is willing to go to the extremes to undo it.
- Large Ham: Once you get him angry.
- Light Is Not Good: In his true form.
- MacGuffin: The clock he uses to travel back in time.
- MacGuffin Melee: The clock contains Gustav Decobra's heart and the two end up fighting over it.
- Make Wrong What Once Went Right: He plans to kill Warren McGuinnis as a child so that his son Terry is never born, never becomes Batman and never causes the events that turned Derek into Blight.
- Maybe Magic, Maybe Mundane: it's never clear if Olive and other students got sick because of vampires draining their blood, or because he was giving everyone radiation poisoning.
- Names to Run Away From: Blight.
- Outside-Context Problem: Time-traveller with radiation-based powers in a story mostly dealing with forgotten mysteries and occasional classic Batman villains.
- Poisonous Person: Walks around the Academy, giving people radiation poisoning.
- The Reveal: He is Blight from Batman Beyond traveling back in time to kill his archenemy's father as a child.
- Shout-Out: He has hidden a still-beating heart under the floor, a clear reference to The Tell-Tale Heart
Outsiders
Gotham City
Silverlock Family
Sybil Silverlock
- Alliterative Name: Sybil Silverlock.
- Ax-Crazy: Implied to be this when she wasn't on her medications.
- Doesn't Trust Those Guys: Tells Olive not to trust anyone in her posthumous letter.
- Good Parents: Olive certainly sees her this way. Olive constantly defends her against insults and is on poor terms with Batman as a result of him putting her away. There are also a number of pictures of the two smiling together.
- Meaningful Funeral: Has this in the eighth issue when it was determined that she could not be resuscitated. Olive and all of her friends attended. Before this, she was:
- Not Quite Dead: Mentioned to be in a coma on life support after the collapse of Arkham Asylum. She has little to no chance of recovery. She was finally put to rest in the funeral mentioned above. She might be dead, but her role in the story is far from over if the strange wraith seen behind Olive and the letter she sent to Olive (mostly likely via Killer Croc since it was found in a lake) is any indication.
- Playing with Fire: Her superpower and a damn effective one at that.
- Posthumous Character: Already in critical condition by the start of the story before being officially declared dead later on.
- Red Eyes, Take Warning: Like her daughter, her eyes seem to glow red when surrounded by fire.
- Tortured Monster: When she has Calamity completely at bay she does not at all care for what Calamity has turned her into, and is mortified to discover she murdered her husband. In one of the last flashbacks shown of her it's revealed that she decided to commit suicide to free herself of Calamity.
Wayne Family
Bruce Wayne
- Badass Normal: He's Batman. Enough said.
- Creepy Good: He's clearly trying to keep Olive safe when they cross paths, but she's so perturbed by him that she won't cooperate.
- Dark Is Not Evil: Absolutely terrifying to the average person, but ultimately trying to reduce crime in Gotham. On the other hand, Olive doesn't buy it.
- The Dreaded: Not only criminals this time, but for Olive as well. She blames him for tearing her family apart and getting her mother thrown into Arkham. For the same reason she defends Killer Croc by setting an entire building ablaze. This has gotten to the point that she has hallucinations of Batman when Bruce Wayne approaches.
- Stealth Hi/Bye: The Trope Namer.
- Wealthy Philanthropist: Provides much of the funding for Gotham Academy and visits the place to give speeches quite frequently in his public identity as Bruce Wayne.
Damian Wayne
- Adaptational Attractiveness: He wasn't ugly (usually) per say in the comics but he was often portrayed with a scrunched up, babyish, round face under Gleason and Morrison to the point of Gonk. Here he very much resembles his father, with a chiseled chin, broad shoulders, striking blue eyes, and a nicely tanned complexion.
- Adaptation Personality Change: He's more chatty and uses his "tt" less often. While still arrogant, he's more empathetic to the thoughts of others and even defends Maps in class. His threats and insults have a lot less bite to them too, being no worse than "Don't make me hurt you." rather than, "I'll kill you."
- Age Lift: Normally, he's around 10 or 11 in the DCU, but in Gotham Academy, he'd have to be in his early teens to be in the same class as Maps.
- Badass in a Nice Suit: Spends the entirety of his appearance in the comic sharply dressed in a blue dress shirt with matching gray blazer and dress pants.
- Badass Normal: Come on, he's Batman's son.
- Blush Sticker: Has this when Ms. Macpherson catches him holding Map's hand and immediately assumes it to be romantic.
- Chained Heat: With Maps. See Sticky Situation.
- Charles Atlas Superpower: A boy who is able to hang onto the ledge with one hand while a girl his age and size hangs on to his other hand, meaning he's lifting more than his own weight with one arm. He's not even sixteen yet! It's a feat that would make every varsity athlete green with envy.
- Covers Always Lie: One cover had him for the seventh issue had him in a jersey while Maps rode on his back. This didn't happen.
- Crazy-Prepared: Brought a bo staff, a grapple gun, and his Batarangs to school. The latter two end up saving him from two nasty predicaments.
- Dare to Be Badass: As Robin, he hands Map a copy of his mask while urging her to go save Olive.
- Grievous Harm with a Body: Used Maps to kick her brother in the gut to incapacitate him (all the other students were under some kind of mind control said to be an avian affliction or curse that rendered them aggressive and incapable of rational thought).
- Insufferable Genius: As usual.Maps: Damian Wayne, oh kid of money. I like your moves, but your attitude's crummy.
- Jerk with a Heart of Gold: During the "Yearbook" arc, he steals Maps' scrapbook...to have her and Olive follow him to find a first edition Serpents & Spells handbook.
- Last-Second Word Swap: Forgets that he's not in costume for a minute at the end and nearly declares his father to be Batman.Damian: Just as I thought. A simple affliction, as my fa- I mean Batman discovered years ago.
- Mythology Gag: His dialogue from the grapple gun scene is ripped straight from the 1989 Batman Movie. Look here
around 2:57. - Nerves of Steel: Comes with his assassin training and being Robin. Even hanging from a window ledge with only one hand free while another girl his age hangs from the other does little to his self-confidence and tactical mind.
- Oh, Crap!: His expression when the headmaster catches him.
- Put on a Bus: Expelled right after his debut chapter.
- The Bus Came Back: Drops by in costume to tell Maps to stay out of the Robin War. He appears in costume again in issue #16 to confiscate Maps' scrapbook...for some reason.
- In an interesting turn of events, the gang runs into him again after they break into Wayne Manor while following a clue, leading him to help them fend off some other intruders with a bo staff and katana from a hidden armory.
- Ship Tease: With Maps. The magic spell that got them into their predicament was written as: Maps Mizoguchi + Damian Wayne.
- Shout-Out: His deductive and tactical mind, his clothes, his skepticism in regards to magic, and most importantly his hairstyle in the seventh issue bring a certain famous Japanese detective to mind...
- Stealth Hi/Bye: It runs in the family.
- Sticky Situation: For almost the entirety of the seventh issue his right's hand was stuck to Map's left hand due to a magic spell she accidentally used by writing with the headmaster's quill pen. He doesn't believe it's actually magic, though, despite fighting magical criminals before and meeting the Justice League.
- Taking the Heat: Ends up doing this for Maps after the headmaster caught her with his quill pen. It gets him expelled (though the headmaster's apparent animosity with the Waynes made things worse).
- Thou Shalt Not Kill: Damian (as Robin) is visibly unnerved when Maps says that Olive is irredeemable and deserves to be put down and begins to try to talk her out of it before being cut off by a massive explosion in the distance.Maps: We need to bring her down before she hurts anyone else. She's beyond saving.Damian: Y'know, I used to think that way until-
- Verbal Tic: Retains his well known "tt" (speculated to be the sound of clicking his tongue) from his home series.
- When He Smiles: Gives his first genuine smile of the comic after bailing Maps out at his own expense. It looks pretty good on him.
Arkham Asylum
Killer Croc
- Adaptational Heroism: Normally portrayed as a misanthropic, cannibalistic creature that's more animal than human, here he's decidedly more kind and nurturing, protecting Olive from the falling debris and giving her safe passage to shore before slinking back into the depths.
- Because You Were Nice to Me: Sybil's mother had her fits, but she was ultimately a calming influence on Croc, leading him to bond with Olive in turn.
- Mutant: His origin story.
- Gentle Giant: To Olive. He's willing to risk harm to protect her and the feelings of companionship are mutual.
- Mythology Gag: Happlly mentions that he threw a rock at Batman once.
- Nigh-Invulnerable: Doesn't even flinch when he's shielding Olive from falling, burning debris.
- Oh, Crap!: Has this when he sees Batman's smoke pellets rolling into the room.
- Super-Strength: As per comic version.
- Took a Level in Kindness: Batman's opinion of him implies that Croc wasn't always as pleasant as he is now. While he's still dangerous enough to kill people if he deems it necessary, he's surprisingly jovial and cordial to Olive and her friends.
Other Outsiders
Gustav Decobra
- The Bus Came Back: Not seen in comics since 1976.
- Classical Movie Vampire
- Cool Versus Awesome\Evil Versus Evil: Gets into a fight with Blight from Batman Beyond
- Killed Off for Real: Ends up being killed by Maps.
- MacGuffin: His heart, which he has hidden in a clock, that somehow turned it into a time portal.
- MacGuffin Melee: Fights with Blight over the clock containing his heart
- Maybe Magic, Maybe Mundane: It's never made clear if he was responsible for Olive and half of the school getting sick by drinking their blood, or it was Blight giving everyone radiation poisoning.
- Our Vampires Are Different: A classical vampire to the t, except for being able to remove his own heart and hide it in a clock.
- Outside-Context Problem: Up until this point the heroes dealing mostly with mysteries and classic Batman villains, a legitimate vampire is something new. Although it didn't stop Pomeline from being prepared anyway.
- Soul Jar: the clock hiding his heart
