- Foe Yay:Vampire!Joker: Batsy You complete me.
- Inferred Holocaust: Vampire Joker and Batman have a brawl in a blood bank, Joker drinking gallons of it and even more being spilled in the process. Considering blood supplies are in short enough supply in the real world, that means hundreds, if not thousands, died because of lack of transfusions.
- Hilarious in Hindsight:
- This wouldn't be the last time the Joker told Batman "You complete me."
- It also wouldn't be the last time Batman gives some of his own blood to Joker in order to cure him of a type of virus. Something very similar to that happens in the Batman: Europa comic and Batman: Arkham City.
- In this film, Peter Stormare voices Dracula, and one of his main goals is to resurrect his dead bride Carmilla. Stormare would later play yet another vampire character named Godbrand in the animated series Castlevania (2017); in which he is (ironically) not only a high-ranking minion serving under Dracula, but is also attracted to another vampiress named Carmilla.
- Narm: The "reveal" that Alucard spelled backwards is DRACULA!
- Older Than They Think: Much, much older. One of the earliest ever Batman villains was actually a vampire called "The Monk", whose debut and storyline was in 1939, soon after Batman's debut, and nearly a year before even The Joker's debut.
- What Do You Mean, It's for Kids?: While still made for general audiences, the movie is considerably darker and bloodier than the The Batman series its based on. Toonami even mistakenly gave it a TV-Y7 rating during its first airing and only later upgraded it to a (much better fitting) TV-PG. I mean, we see Penguin bleeding on Draculas shrivelled-up body for crying out loud...
YMMV / The Batman vs. Dracula
