Continuity Nod in this franchise.

Comic Books

  • Animal Man: Issue #88 from the Jerry Prosser run shows Annie has the mask of B'Wana Beast, last seen on Tom Veitch's run, hanged on her bedroom. It's one of the few references the Vertigo run has to the main DC canon.
  • America vs. the Justice Society: Too many to count, such as Batman recalling his Early-Installment Weirdness of using a gun.
  • Amethyst, Princess of Gemworld: When Amethyst learns how to form shields with her magic she compares it to Wonder Woman's bracelets. Makes sense with how there's a very prominent poster of the Amazon Princess on her bedroom wall at home.
  • Angel and the Ape: The Green Glob (which played a major role in the Phil Foglio miniseries) was a running feature in DC's Tales of the Unexpected back in the 1960s. Really!
  • Aztek:
    • In issue 7, there's a promotional poster of a boxing match between Bibbo Bibbowski and Ted Grant.
    • In the final issue of Aztek, it is revealed that the JLA has a ceremony of sorts for new members, which involves the costume of the Crimson Avenger, "the first of [their] kind".
  • Batgirl:
    • Batgirl (2009)
      • When trying to dissuade Stephanie from continuing as a costumed crimefighter, Barbara points out that her history is so bad that she actually used Stephanie as an example of why other teenage girls should not become vigilantes, including presenting photographs from her faked autopsy. This occurred in the first volume of Birds of Prey, where the teenage runaway Charlotte Gage-Radcliffe used a homemade costume to fight crime as Batgirl.
      • Issue #19 partially deals with Barbara's life and plans now that Oracle is dead. That storyline concluded in Birds of Prey (Vol. 2) #10, which was released the same day and included Batgirl as a character.
      • Grant Morrison worked with Bryan Q. Miller to line-up Batgirl with his Batman Inc. series. Morrison planned to write an issue which saw Stephanie head to England to infiltrate a boarding school for teenaged assassins, so Miller wrote an issue of this series which featured Batgirl traveling to London. However, the planned issues of Batman, Inc. were not published until after the cancellation of Batgirl and were released as a non-canon oversized one-shot.
    • Batgirl (2011)
      • The first issue of the series includes recreations of several panels from The Killing Joke, where Barbara was shot and paralyzed by The Joker.
      • Issue #7 has graffiti on a sewer wall that reads DARK VENGEANCE, which was the catchphrase of the teenage superhero (and onetime, unofficial Batgirl) Misfit. Barbara had mentored Misfit in the pre-reboot Birds of Prey. She shows up in the flesh in Issue 34, shouting her catchphrase during a fight.
      • The #0 origin issue closed with a recreation of a panel from The Killing Joke where Barbara was about to be shot by the Joker.
      • When Ragdoll makes a guest appearance, he's seen talking to someone on his cell phone regarding their employer. He finishes the conversation with "Give my love to your wives." It is blatantly implied he was talking to Scandal Savage as Gail's way of stating that Scandal's marriage to Knockout and Liana Kerzner is still canon.
      • After getting thrashed by Batwoman (in a case of Let's You and Him Fight), Batwoman offers Batgirl a handkerchief to clean her bloody nose. Babs is incredulous that Batwoman would carry such a thing in her utility belt. Over twenty issues later, however, Batgirl has started carrying one as well, as she offers it to Huntress after beating her up in an almost identical situation.
  • Batman:
    • Writers and artists often use scenes set in the Batcave's trophy room to give a nod to previous stories. Traditionally included are the giant penny from a 1947 fight with The Penny Plunderer, a T-Rex from a 1946 adventure on Dinosaur Island, and a memorial to Jason Todd, first seen in The Dark Knight Returns.
    • A Death in the Family was possibly the first 'mainline' comic to acknowledge the events of The Killing Joke, noting the superhero community and especially Jason are furious with the Joker for what he did to Barbara. Later, the wheelchair-bound Barbara is seen attending Jason's funeral.
      • Prior to his (not quite) final confrontation with the Joker, Batman briefly recalls the events from Batman: The Cult, admitting to himself that he still hasn't fully gotten back in shape yet after his confrontation with Deacon Blackfire.
    • Also, Batman once investigated murders at a movie set, where the movie being shot was a WWI flying action/drama. The misunderstood Villain Protagonist of said film was Hans von Hammer, in our world the main character of DC Comics' Enemy Ace series.
    • All-Star Batman & Robin, the Boy Wonder: There are several to other Dark Knight Universe stories.
      • DKR's Battank being built in the Batcave.
      • The Batcave is full of these. Besides the aforementioned Bat-Tank, there are:
      • The Bat-Glider from Batman: Year One,
      • The Bat-Copter from The Dark Knight Returns,
      • The Bat-Shield Batmobile,
      • The 60s Show Batmobile,
      • And the Batwing from the 'Hush' storyline, also penciled by Jim Lee.
      • Joker's henchgirl Bruno and Batman saying the We have to be Criminals line.
      • Also, Batman's character is identical to Frank Miller's in Batman: The Dark Knight Returns, save for him being 20-30 years younger. When TDKR came out, the story seemed to imply it was the decades of superheroing that turned Batman into this sour, cynical person. This story retcons that into Batman having started out as more of a jerkass than in TDKR and growing more noble, responsible and humane as he grew old, probably thanks to Dick Grayson's influence. This is a bit ironic if you consider that Grayson is revealed to be a complete psychopath in TDKSA. During their climatic battle, he implies that Bruce's negligence and lack of affection drove him insane. Miller's Batman predictably scoffs and pushes him into hot lava.
      • A subtle one is on the cover of the first issue, with Batman swinging over Gotham. His face is blacked out with only his eyes visible, similar to the covers for The Dark Knight Returns collected editions.
      • Gordon's story about taking a baseball bat to Flass occurs in Batman: Year One, though not the way he makes it sound.
    • Batman and Robin (2009): Gordon remarks that he hates Pyg's hideout. It's because it's implied to be the same amusement park where the Joker kidnapped him and tried to torture him in The Killing Joke.
    • Batman Beyond (2016): When the Batsuit is rendered unusable, Tim uses "Rookie", the Mini-Mecha that Jim Gordon used during his time as Batman to fight Brother Eye during the events of Batman Superheavy.
    • Batman (2016)
      • Batman (James Tynion IV): Nightwing mentions that Batman had considered Ghost-Maker as a possible candidate for Batman Inc., which he eventually becomes the leader for.
      • Batman (Joshua Williamson):
      • Bruce's isolation, as a result of many of the people he regularly talks to not being around. These events themselves are in other series.
      • When Bruce reflects on his past with Lex, he recalls Forever Evil, Justice League (2011) and Justice League (2018). It's also made clear that, despite the Soft Reboot of Infinite Frontier and the ending of Grayson, Lex still retains his knowledge of Bruce's identity as Batman and Dick Grayson's identity as Nightwingnote 
      • Batman (Chip Zdarsky): Tim still does not like the idea of being considered crazy at believing the idea of Batman not being dead, something he went through badly during the post-Final Crisis era and Red Robin.
    • Batman Eternal
      • Cross-continuity, that is. Upon the reveal of Blackfire as a major villain, the death of said villain in Batman: The Cult is gone over by Vicki Vale's newspaper in summary for new readers.
      • There is mention of Nightwing's "death" from Forever Evil when Batgirl talks to Red Hood.
      • When fighting Mister Freeze, Batman utilizes heat gauntlets like the ones he had when fighting him in his first New 52 issue or Arkham Origins.
      • During a conversation with Harvey Bullock in issue #37, Maggie Sawyer remarks that she no longer has anyone "warm and redheaded" to wake up next to, a reference to she and Kate Kane breaking up in Batwoman #34.
      • In Issue 46, several of the other "Batmen" are shown, including the older Bruce from the Kingdom Come universe and various successors Terry Mcginnis, Damian Wayne, and Dick Grayson.
      • Among the future Batmen Bruce sees, in the bottom left of the page is one from the 75th anniversary issue, recognizable by their distinctive orange Tron Lines.
    • Batman: Hush: Being a Loeb story, it's a cavalcade of continuity references, a good deal of them to The Long Halloween and Dark Victory.
      • The Falcone penthouse shows up in #613.
      • Dent mentions that the Joker broke into Dent's home and beat him up. This was in The Long Halloween #4.
      • Scarecrow talks in nursery rhymes again.
      • Whole-Plot Reference to the above stories: A mysterious new villain shows up with a new scheme, in the process testing the Batman’s resolve while he deals with his existing Rogues.
      • Much of the arc is an Internal Homage to the most iconic Batman stories. Batman gets into a fight with Superman (Batman: The Dark Knight Returns), is dealt a seriously debilitating injury (Knightfall), deals with a seemingly resurrected Jason Todd (A Death in the Family), gets into a swordfight with Ra's al Ghul in a desert in the Middle East (the famous O'Neil/Adams run), and contemplates killing the Joker after he crosses the line one too many times (The Killing Joke).
    • Batman: Last Knight on Earth: While the Black Label encourages and promotes out-of-canon imaginary stories, Last Knight on Earth features many Call Backs to the various plot threads Scott Snyder set in stone during his run. Most notable is the plot point of a machine the original Bruce Wayne invented to create a new Batman for each succeeding generation as a contingent for his eventual passing.
    • Batman: The Last Halloween: In issue #2, the Mad Hatter is Bruce's initial suspect for James Jr.'s kidnapping. The reason is because Tetch had previously kidnapped a young Barbara Gordon on Halloween (which had occurred in Loeb and Sale's second Batman Halloween Special in 1994).
    • During Nightwing and Batgirl's conversation in Forever Evil (2013) #1, Babs references the recent Death of the Family crossover and the Bat Family's currently strained relationship with Bruce.
  • In Issue #2 of Red Hood and the Outlaws, Red Hood gets an air hostess' number. They met in Batman #426, 20 years ago. She still remembers his drink order, although in modern continuity, they probably met 2-3 years ago. And he mentions 'A Death in the Family', although that is a Shout-Out. Her name is Isabel Ardila, by the way.
    • In issue #6, it's revealed that Red Hood's costume is actually one of Nightwing's old costumes. Though in-universe information is lacking thanks to the recent reboot, it seems to be based on Nightwing's Renegade costume.
    • The Night of the Owls tie-in nods to the revelation in Batman that Haley's Circus (of which Nightwing was a performer) was a recruitment service for the Court of Owls. It may also be a reference to Red Hood's pre-Crisis history as a circus performer.
    • The Death of the Family tie-in has the Joker forcing Jason to relive the circumstances of his death in the original A Death in the Family arc.
  • The Sandman (1989):
    • In The Sandman: Endless Nights story, "The Heart of A Star"— Superman's ultimate origin is revealed to be a conversation between Krypton's sun and the first personification of Despair on the nature of beauty. This story also features a character called Killalla of the Glow, who is implied to be one of the first aliens to master the energy later marshaled by the Green Lantern Corps.
    • It's never directly stated, but there are enough hints to figure out that Matthew the raven was Matthew Cable, from Swamp Thing, before he died.
  • Supergirl:
  • Superman
  • Teen Titans
  • Young Justice (1998):
    • Issue #2 features Impulse asking Ali Ben Styn for a spaceship as a reward for saving him from Rip Roar in a seemingly throwaway joke. Issue #25 features him finally getting it as they need it to bring Doiby Dickles to Myrg.
    • Issue #1,000,000 features a statue of a young Lobo in the headquarters of the Young Justice Legion T. #54 features Slobo being transported to the future by Darkseid's Omega Beams, revealing the statue is actually Slobo's petrified body since he was dying of clone degration.

Film

  • Batman Film Series:
  • Batman: Assault on Arkham
    • The Joker mentions having worked with Deadshot before.
    • The Iceberg Lounge is shown, including the walkway balcony from which the Penguin will end up shooting at Batman a few years later.
    • Bane is, again, dispatched by being dumped into the Gotham Bay. Likewise, Poison Ivy creates a giant flower and brainwashes a large number of the Arkham staff. And once the situation is under control, Batman leaves via Batwing to deal with another criminal that has escaped to Gotham.
    • Several of the rooms seen in the game are identical to how they appear in Arkham Asylum (Without the obvious damage the game's event causes on them). In particular, the room containing the Joker's cell (Circular room lined with high security cell, electrifyable floor and a tower in the middle - in the game it is where Batman captures Harley Quinn), and the underground ruin room where the team re-joins Killer Frost and the Riddler.
    • Some of the things Batman does refer to the Arkham games:
      • In particular using his cloak to strike an opponent when facing a knife wielding mook, which is how the player deals with blade-enemies in the game.
      • He also uses explosive gel, an Arkham mainstay, by shooting some in Bane's face and detonating it.
      • The entire fight against Waller's team in the opening is very similar to the games' Freeflow combat system in its execution to the point where as mentioned above, some of the moves are lifted straight up from the games. Batman moving from foe to foe, vaulting over some, attacking them all - with the occasional gadget, till they are all down is very familiar to anyone who has played the games.
      • Batman uses electric knuckle dusters, similar to the gauntlets he got off Electrocutioner's body in Arkham Origins.
      • Batman rides the back of Bane for a moment, as he stumbles and strikes things and inmates blindly. Batman pulls this move against most large enemies in the games, including yes, at one point, Bane himself.
      • He briefly uses a version of Detective Vision, which lets him see who is riding away from Arkham in the Helicopter. Unlike the games' it doesn't give him the outline of their skeletons, but does show their pulse and makes his eyes glow when he uses it like in the game.
      • And of course, Batman uses his grapple gun to get to the Batwing, which is how he gets in it every time in Origins when it is not landed.
  • Batman Beyond: Return of the Joker
    • Commissioner Jim Gordon, Dick Grayson/Nightwing and Leslie Thompkins are mentioned, but they are not seen. Also, in the uncut version, Bruce is practicing his batarang-throwing against replica statues of some of his old Rogues Gallery.
    • When Bruce is comparing audio files to determine if the Joker that appeared at the party is the same as the one he fought, the first sample he examines is from a threat video Joker made back in the episode "Holiday Knights".
    • In the original version of the flashback sequence, Batgirl questions her informants from the TNBA episode "The Ultimate Thrill". (cut from the bowdlerized version, presumably because they appear to be hookers.)
    • The Joker's plot ultimately relies upon stolen microchips that brainwash his victims into both doing his bidding and overwriting their DNA with his own. Joker mentions that he stole the basis for this technology from various places over the years, with the first instance coming from the BTAS episode "Make 'Em Laugh", where he steals mind control chips from Mad Hatter.
  • Batman: Hush (2019): Lex Luthor mentions how he saved the Justice League from Cyborg Superman, a reference to the events of Reign of the Supermen.
  • Batman: Mask of the Phantasm: The socialite angry at Bruce for dumping her had previously appeared in the episode "Joker's Wild", wearing the same hairstyle, evening dress, High-Class Gloves, and fur wrap.
  • Batman: Mystery of the Batwoman: At one point, it's mentioned that a faction of the Kaznian military is attempting to purchase weaponry from the Penguin and Bane. Kaznia was first mentioned in Superman: The Animated Series and later played a crucial role in several episodes of Justice League.
  • Batman: Return of the Caped Crusaders: Dick Grayson claims that their greatest foes have RE-united. Nodding to the first time they united in the 1966 movie.
    • The credits reference the famous "Some days you just can't get rid of a bomb" scene and the Batusi.
  • ''Batman: Under the Red Hood'
    • Names such as the Penguin, Harvey Dent and the Scarecrow are bandied about by Jason, and he also references "friends [Joker] has crippled". The Joker's quip about the camera could also be a veiled reference to the events of The Killing Joke.
    • When Batman has the flashback of him cornering the Red Hood that would become the Joker at the chemical plant, the Red Hood pleads that he's not a criminal and that he was forced into the job. This could indicate that this version of the Joker has the same backstory as the one from The Killing Joke.
    • The powers that Amazo uses (super strength, flight, laser eyes) were most likely absorbed from Superman.
    • Black Mask rubs his neck nervously staring at a burning piece of black wood. His face became like it is due to a black wooden mask being burned into it.
  • Batman Unlimited: Monster Mayhem: Batman still has Ace, the robotic wolf with the motorcycle form that he acquired from Penguin in Batman Unlimited: Animal Instincts. Red Robin's glider is a robotic bat from the film as well.
  • DC Showcase: Catwoman: The art style is identical to that used for the Batman: Year One animated film, although the setting is more modern. The end of the film demonstrates that Selina has the same shaved haircut and Holly Robinson appears in her Year One design.
  • Green Lantern: Emerald Knights: Laira's Transformation Sequence when she first puts on the ring is the same as Hal's from First Flight.
  • Justice League Dark: While trying to dissuade Batman's Arbitrary Skepticism Wonder Woman mentions Shazam and Trigon.
  • Justice League vs. The Fatal Five
    • Word of God refers to Mr. Terrific as one of the three smartest men in the world (but not the smartest) and the smartest man in the Justice League, which almost clears up what Batman said to Amanda Waller in "Panic in the Sky" (indirectly saying that Lex Luthor was the smartest man in the world). The identity of the second smartest man in the world in the DCAU has yet to be revealed.
    • Persuader cleaving Jessica's ring recalls when Hro Talak did the same to John in "Starcrossed".
    • All Arkham inmates have been moved to a more modern, secure facility, as Barbara stated to have happened during the flashback sequence in Batman Beyond: Return of the Joker.
  • Wonder Woman: Bloodlines: Diana's now-ended romance with Superman, her meeting the president, and the battle against Darkseid are mentioned.

Live-Action TV

  • The Penguin (2024): As part of the Viral Marketing for this show, a group of the Riddler's "fanclub" brought The Riddler's site back online. Three of the users — Cl0ckbreak3r, xxREIGNITINxx, and HOLDTHELINE81 could be seen commenting during Gil Colson's explosive livestream, while the fourth user — DETERMINATOR — left a comment on the Riddler's last video.

Video Games

  • Batman: Rise of Sin Tzu: The four villains from Batman: Vengeance (Joker, Harley, Ivy and Freeze) are seen in the same cells at Arkham that they were placed in at the end of that game. The novel explains they've been turned into living trophies by Sin Tzu.

Western Animation

  • Batman: The Brave and the Bold: Even Sherlock Holmes gets one, as one of his first lines in his episode references the events of Arthur Conan Doyle's story The Adventure of the Empty House.
  • Creature Commandos (2024)
    • In the first episode, Amanda Waller mentions that Rick Flag's son was killed during a mission in Corto Maltese, as seen in The Suicide Squad.
    • A major plot point is that Waller has been forced to use non-human prisoners after Task Force X was revealed to the public by her daughter Leota during the first season finale of Peacemaker. Likewise, John Economos is shown using a crutch due to the injury he sustained while helping fight off the Butterfly aliens in the Peacemaker finale.
  • The DC Animated Universe had tons of Continuity Nods throughout its run.
    • Justice League:
      • In "Hereafter", the trunk of the car Superman is driving has a box of the energy bars Flash was hawking in "Eclipsed", and Deadshot smuggled a gun into the watchtower by hiding the parts in wrappers of the same bars in "Task Force X." "Flash and Substance" featured a cardboard cutout of him in his apartment, still advertising the same energy bars, which is destroyed when it startles Orion.

      Flash: [Bummed out] Dude, that was my last standee.

      • In "Clash", Superman brings up deodorant advertisement deals in his lecture to Captain Marvel—the way Flash covers his face indicates that he takes this as a dig against his energy bar commercials.
      • In "Hearts and Minds", Katma Tui brings up that John Stewart sent Green Lantern Kyle Rayner to Oa for training after receiving his ring, accounting for his absence since his introduction in "In Brightest Day..." in Superman: The Animated Series.
      • In "Question Authority", Huntress uses Jimmy Olsen's signal watch to call Superman; the watch first appeared in "Superman's Pal" in Superman: The Animated Series.
      • Another reference appears in "Only a Dream" when, during his nightmare, Superman calls Jimmy "my pal."
      • In part two of "The Once and Future Thing," Green Lantern alludes to a past team-up with Static. This references "Fallen Hero", an episode of Static Shock that Green Lantern guest-starred in.
      • Lex Luthor has cancer from manipulating kryptonite for years. The first mention of the disease was in Superman: The Animated Series, when the Joker stole a jade dragon statue. Every past owner fell ill and died, because it actually was made of kryptonite.
      • The entire Cadmus Arc from Unlimited is essentially based off of the last episode from Superman: The Animated Series, and indeed, its conclusion refers to events as far back as the middle of the show's second season.
    • A classic from Batman: The Animated Series; in the episode "Pretty Poison", Pamela Isley, (a.k.a. Poison Ivy), is dating Harvey Dent (the future Two-Face), intending to kill him for destroying a nature preserve to build "Stone Gate" prison. Later in "Almost Got 'Im", Poison Ivy and Two-Face meet in a Bad Guy Bar and start trading insults. Ivy then turns to Joker, Penguin, and Killer Croc and explains, "We used to date." (There's a bit of dramatic irony here in that Joker, Penguin, and Croc all respond with a casual "Ah....", probably thinking something along the lines of "she must have been a total bitch to him." They don't even realize that she almost murdered him!) Then again, considering the kind of relationship the Joker has with his girlfriend...
      • When the inmates of Arkham Asylum puts Batman on trial, it's one big nod to the first appearances of each of the villains who "testify" against him.
      • In the Batman: The Animated Series episode "The Clock King", the paper Bruce was reading has a photograph of someone who seems like Maven, Selina Kyle's assistant, with a cat that seems like Isis, both from the episode "The Cat and the Claw". The header says: "Kolus cat saved".
    • Batman Beyond:
      • The Batcave is filled with relics from Bruce Wayne's crimefighting career, in the original Batman: The Animated Series. This merges with Chekhov's Gun when Bruce uses Mr. Freeze's cryogenic gun to subdue a villain when she invades the cave. In another episode he dons the goggles and hat of the Grey Ghost, his childhood hero, to mask his identity.
      • In the same show, there is an odd example of a Mythology Gag becoming a sort of retroactive Continuity Nod: the elderly Bruce Wayne's pet Great Dane is named Ace, which was also the name of the Bat-Hound, Batman's pet dog who appeared in his comics during the 1950s and '60s. In a later episode, though, we learn about one of his later adventures as Batman, and the name of "Ace" takes on a whole new meaning: Namely, the suggestion that Ace is named after Ace of the Royal Flush Gang, whom Batman stayed with as she slowly died in the Justice League episode "Epilogue".
      • And that episode was also filled to the brim with Continuity Nods, considering it was intended to be a Grand Finale. A visual that referenced the first episode of Batman: The Animated Series, connecting a Joker plot in Justice League to the Batman Beyond movie, the random appearance of a villain we haven't seen or heard from in over a decade, the list goes on.
      • Terry McGinnis goes to Hamilton Hill High School, named after Gotham's mayor in Batman: The Animated Series.
      • One of these relics actually makes a pretty good explanation for the unexpected reappearance of a certain character at the end of Return of the Joker. Even though said reappearance was a last minute decision. When Inque infiltrates the Batcave during the series, Harley Quinn's costume can be seen among the trophies. Even though not stated directly by the writer, it created the idea among fans that Barbara might have lied to Terry about Harley Quinn's end. That she either didn't fall into the chasm, Batgirl managed to pull her up, or that they actually checked for her body and found her alive and covered up her survival to prevent Tim from taking revenge on her. This could also be seen as unintentional continuity nod.
    • The Splicers, people who use LEGO Genetics as a form of body-art akin to tattoos & body piercing use technology descended from that used to create Man-Bat, as well as the various cat monsters in "Tyger, Tyger".
      • A very nice touch is the fact that the relic given pride of place in the cave (apart from the suit rack) isn't a trophy from a case, it's the costume of The Gray Ghost, Bruce Wayne's in-universe inspiration for his vigilante career.
  • Teen Titans (2003) has several of these, including the baby moth monster that Beast Boy keeps as a pet and Starfire drinking mustard as if it were a normal drink.
    • The New Teen Titans shorts do this in the short "Blackfire's Babysitter" by not only referencing Blackfire's marriage, but revealing that she got saddled with four kids.note 
  • Young Justice (2010)
    • "Denial" shows that Kid Flash actually has a room full of shelves where he keeps the 'souvenirs' he picks up every episode. The shelf reappears in many following episodes, each time with more and more souvenirs. In Season 2, Beast Boy continues this tradition.
    • Artemis is placed in danger of drowning in the episodes "Homefront," "Alpha Male" and "Revelation," which each aired one week after the other. In each near-drowning she complains at how frequently it occurs, finally revealing that she now carries artificial gills because of what has happened.
    • In "Revelation" The Helm of Nabu is used as a last resort in the battle against the Injustice League to allow Aqualad to become Dr. Fate. Kid Flash worried that Nabu would not let Aqualad free, as he had earlier threatened to do to Kid Flash in "Denial". Later, in "Misplaced" the Helm of Nabu is used again in another desperate situation, ultimately resulting in Giovanni Zatara becoming the new Dr. Fate permanently to spare his daughter Zatanna.
    • In "Schooled", each of the Team's members were given motorcycles as part of an undercover mission, and Conner eventually abandoned his after gaining the Super-Cycle in "Disordered". Conner's motorcycle reappeared in "Secrets", where it was used by Zatanna.
    • In "Schooled", Superboy says "I hate monkeys" when fighting robot ones. He repeats this when encountering all kinds of simians, including the villainous Monsieur Mallah and Ultra-Humanite and a normal pet monkey. In season 2 Superboy fights alongside Beast Boy, who shape-shifts into a gorilla (and whose default form is a monkey-boy), softening his stance toward monkeys.
    • In "Misplaced," Kid Flash explains to Artemis that Dr. Fate previously defeated Klarion the Witch Boy by attacking Teek'l, his cat familiar ("Denial").
    • During a mission, Kid Flash suffers a broken arm and the cast does not come off until several episodes later.
    • The South Rhelasian Prime Minister from Season 1 has become Secretary-General of the United Nations in Season 2.
    • In "Alienated", just before J'onn leaves to stand trial, he asks M'gann to water his plants while he's gone. In "Cornered", when M'gann disguises herself as her uncle and moves into his apartment, the first thing she does is water the plants.
    • Beast Boy is revealed to be dating Queen Perdita, the young girl Wally West saved from Count Vertigo in the Season 1 episode “Coldhearted”. When pressed for details, Beast Boy explains that they met at Wally’s funeral following his death in the Season 2 finale.
    • Beast Boy also transforms into the alien bird-creature he met on Rann at the beginning of Season 2 when he wants a form with speed and agility.
    • Superboy says that "[he] feels naked, and not in the fun way", borrowing Artemis's words from Season 1.
    • Superman, of all people, has started using "aster" and "whelmed" when talking. It's not limited to The Team anymore.
    • Rocket's living room contains a photograph of the original 8 members of the Team in winter clothing circa the end of Season 1.
