As usual for a LEGO Adaptation Game, references to other continuities are prevalent, but this game seems especially dedicated to doing so.
- Deadshot's idle animation includes him putting on a top hat, which his original costume included.
- One of the challenges in the open world is to find and destroy a number of chattering teeth.
- An obligatory one from the background chatter in Smallville:"You know, back in the noughties, this place was in a very famous TV show." (Which may double as a Shout-Out to BoJack Horseman, of all things.)
- At the beginning of the second level, the Riddler asks the riddle "when is a jet stream like a daffodil?", which is one that he also asked in the '60s TV series. Like in the series, the answer is not given.
- One achievement involves taking a selfie with Batman while playing as Joker and is titled "The Enemy Within".
- One of Riddler's combat quotes references a scene from Batman Forever.Riddler: How did that advice go again? "Ball up the fist, reach way back, and assert yourself." Got it.
- Another reference to Batman Forever is a trophy earned from visiting the Batcave as Two-Face and the Riddler.
- One of Joker's combat quotes is, "Looks like these guys want to see a magic trick!''
- On Apokalips, Joker is running around like a tourist with a familiar old film camera.
- King Shark's bio, alongside his Catchphrase, helpfully inform you that he is a shark.
- Black Manta implies that King Shark has a history of friendship with Harley and Ivy during the mission with Ivy, Shark, and Manta.
- A text you can receive asks, "How do you track Deadshot in the snow?" The answer: "Look for the Fresh Prints."
- One of Green Arrow's quotes upon collecting a gold brick is, "Can't accuse me of failing any cities today!"
- Kanto taunts Flash about being too fast to get a date.
- The inmate in Arkham who became Hugo Strange's test subject was a man that the Joker apparently knew named Bob.
- In the Young Justice DLC level, during a lengthy fight between Aqualad and Black Manta, Lobo complains that the fight is taking so long he might have to wait six years to see what happens next. This is a reference to the lengthy hiatus between the second and third seasons of Young Justice.
- In "They Think It's Owl Over", during the boss fight with Ultraman, he says:
- When breaking Joker out of Arkham, Lex tells him to change the security monitor to "Channel 52"
- Psycho-Pirate's unlock quest involves him searching in Smallville for some "friends" who scattered around there and need to be "convinced" to go back to working for him. This is a heavily Lighter and Softer reference to Blackest Night, during which a Black Lantern-possessed Psycho-Pirate did some... worse things to the population of Smallville.
- When faced with a puzzle he can't solve, movie!Aquaman will start complaining, perform an Ahem, then exclaim how "outrageous" it is he can't solve it.
