* {{Crossover}}: Between Batman and the IDW incarnation of the Turtles.

* CompositeCharacter: The third crossover is full of these thanks to Krang forcibly merging the Ninja Turtle and Batman multiverses. Bruce Wayne was the child who owned (and named) the pre-mutation turtles, the Turtles wear costumes inspired by the various Robins[[note]]Leo's suit is based off of Nightwing's, Don's is from Red Robin, Raph's is Red Hood, and Mikey's is based off Damian's[[/note]], and Splinter serves his usual role combined with Alfred's. They are shown to oppose the Foot Clan, a fusion of the Foot Clan and Batman's rogues gallery led by a composite of the Joker and the Shredder called the Laughing Man and other members including a fusion of Harley Quinn and Karai as well as a pair of henchmen consisting of the respective combos Bebop/Killer Croc and Clayface/Rocksteady. Characters who aren't merged still have a role in the new universe, like Casey Jones being an honest cop who works with Commissioner Gordon.

* WhamShot: [[spoiler:The penultimate issue of the ''Adventures'' miniseries shows the DCAU incarnation of the Scarecrow drawing sketches depicting how he appeared in ''The New Batman Adventures'', which unfortunately doesn't come up in the final issue in spite of it being indicated to take place during that era of the show's run by Tim Drake becoming Robin and Dick Grayson appearing as Nightwing.]]

The miniseries is six issues long, and ran from December 2015 to May 2016. The sequel has been announced to launch in December 2017 and end in May 2018, telling a story of Donatello trying to establish a portal between Turtles' and DC Universe but accidentally getting stuck in Gotham... while ComicBook/{{Bane}} [[OhCrap got to his world]]. In February 2019, the GrandFinale of the series was announced. It deals with Batman and the Turtles trying to stop Krang from hauling DC Universe-based tech into Dimension X.

* TheEarthPrimeTheory: The third crossover both uses and subverts this. Krang uses the power of the Anti-Monitor to conquer the "prime" versions of the Ninja Turtles universe (the original black-and-white Eastman and Laird comic) and the Batman universe (the mainline DC Comics version) in order to gain power over all the offshoot universes. However, instead of merging them, he merges the IDW Turtles-verse and the universe of the Batman who crossed over with them previously in order to weaken them so they couldn't fight back as effectively, especially since the IDW Turtles had fought and beaten him several times and knew all his tricks.

Meanwhile, there's another crossover series called ''Batman[=/=]TMNT Adventures'', which teams up the Batman from ''WesternAnimation/BatmanTheAnimatedSeries'' with the Turtles from [[WesternAnimation/TeenageMutantNinjaTurtles2012 the 2012 Nickelodeon series.]]

An AnimatedAdaptation called ''WesternAnimation/BatmanVsTheTeenageMutantNinjaTurtles'' was released on May 14 [[note]] digital [[/note]] and June 4 [[note]] DVD [[/note]] 2019.

* BroadStrokes: The first comic series seems to take its inspiration from the IDW comic book series, but since [[spoiler:it ends with Shredder being arrested]], which is never alluded to in that line, it's hard to tell just how faithful it is to that canon. The sequel throws in more divergences, most notably [[spoiler:Baxter Stockman's accidental mutation into a flyman from mutagen exposure]].

* DivideAndConquer: How Batman largely handles the Turtles initially. Using the Batmobile and his gadgets he's able to either keep them from working together, or get them to actively get in each other's way through superior tactics.[[spoiler: When Leo is able to fight Batman one on one, he's able to match Batman skill for skill.]]

-->'''Raphael''': I see right through your dumb cape and cowl, Batman. You want to know what you are? You're just a thrill-seeker. You're some rich guy who puts on a costume and punches bad guys because it seems like fun. You ''chose'' this life. We didn't. We became what we needed to become to survive. We fight Shredder because if we didn't, he'd have us all killed in our sleep. But you don't care about any of that, do you? That's why we failed. If we hadn't listened to you, we could have snuck into that base and gotten home by now. Shut the whole thing down from the other side. We wouldn't be stuck here. We wouldn't have this death sentence over our heads. And for some idiotic reason, ''they'' can't see that. They think you're the hero you pretend to be. But I see the truth. You're just a selfish little rich kid doing all of this for kicks, and that's ''not'' someone I'm going to put my faith in.

* {{Irony}}: In the third crossover, Shredder calls the Laughing Man out for filling his ranks with "garish imbeciles". April smirks and turns to Alfred, remarking "Can't wait until somebody fills him in about Bebop and Rocksteady."

* BroadStrokes: The first comic series seems to take its inspiration from the IDW comic book series, but since [[spoiler:it ends with Shredder being arrested]], which is never alluded to in that line, it's hard to tell just how faithful it is to that canon.

* LetsYouAndHimFight: The first meeting between the Turtles and Batman results in a fight, mostly due to Raphael. There's also the inevitable showdown between Batman and Shredder.
