Over 50 Easter Eggs and secrets you missed in LEGO Batman: Legacy of the Dark Knight

If you miss the days of playing Rocksteady's Batman: Arkham franchise and searching for any potential Easter eggs or secrets, then we have good news, because LEGO Batman: Legacy of the Dark Knight just replicated that same magic in perhaps a bigger fashion. TT Games' latest title is a love letter to the Caped Crusader's entire history across comic book pages, TV series, movies, and video games. As such, it has no shortage of references for players to find (believe me, there are truly a lot).

Some of the game's Easter eggs are a little more obvious than others. At some point in the campaign, we even hear Matt Reeves' The Batman main theme, as well as that haunting Batman: Arkham Asylum jingle. However, instead of focusing our attention on those details that are easy to catch, we're about to break down secrets that players might have missed the first time around. So without further ado, here are over 50 cleverly hidden Easter eggs in LEGO Batman: Legacy of the Dark Knight.

The Court of Owls is always watching

In the comic book world, the Court of Owls is a highly secretive criminal organization comprising Gotham's most powerful and wealthiest citizens. They run the entire city from the shadows, manipulating politicians and getting rid of anyone who stands in their way.

Well, wouldn't you know it, their influence is so big that they even watch your every movement in LEGO Batman: Legacy of the Dark Knight.

Throughout the game's world, you can see graffiti that directly mentions the Court of Owls. Furthermore, you can also see some cryptic imagery that references the court, such as a flyer in a high-fashion store that reads "Your secret friend, whoo?" with a picture of an owl (as seen above).

Perhaps the creepiest Court of Owls Easter egg comes in the form of collectible trophies hidden around Gotham shaped like the members of the court themselves (as seen above). It wouldn't be surprising if there were even more hidden references to this criminal organization, especially since they are watching from every corner of the city.

Lex Luthor makes an appearance, and there are other Superman references

One of the biggest surprises in Batman: Arkham Knight was discovering Lex Luthor's voicemail on Bruce Wayne's office phone. Well, the villain's ego is so big that he wasn't satisfied with stealing the spotlight in Rocksteady's title, so he just had to do the same in LEGO Batman: Legacy of the Dark Knight. As you can see in the image above, the iconic DC antagonist appears in a picture inside an apartment.

That isn't the only Superman reference in TT Games' latest title. When you visit a museum as part of the main campaign, you'll see a green crystal on display. When you approach it, Batman will say, "What a beautiful crystal. Something about it is so... alien."

Fortunately, the Man of Steel isn't there to be weakened by this piece of Kryptonite. And speaking of steel...

On the streets of Gotham City, you'll also find a "Metrosteel" factory, which is short for... Metropolis Steel. It seems this version of the DC Universe is filled with tons of heroes. However, that means there is no shortage of bad guys to keep the good guys entertained.

Speaking of which...

Many Batman villains who don't appear in the game are referenced

LEGO Batman: Legacy of the Dark Knight features the appearance of over 25 iconic and popular Batman villains. While that number is absolutely stunning, renowned bad guys were still left out of the adventure. Fortunately, TT Games still found a way to reference them in some capacity. One of them is Hugo Strange, who is the face of many billboards across the city, as seen in the image above.

Similarly, The Ventriloquist and Scarface also have billboards promoting their upcoming show. These artworks can even be set as the background of the Batcomputer in the Batcave, which is a pretty neat detail.

Another man (or bat?) looking to make a name for himself is Kirk Langstrom. That's right, the Man-Bat himself paid to promote his upcoming musical in Gotham City.

Thomas Elliot has yet to act as the main antagonist of a Batman film or video game. While LEGO Batman: Legacy of the Dark Knight doesn't change that, we can still see references to his alter ego, Hush, hidden across the city.

Similarly, we can spot graffiti that references another iconic DC villain, Gentleman Ghost, who has appeared in adaptations such as Batman: The Brave and the Bold.

The Batcave is a key location in LEGO Batman: Legacy of the Dark Knight. In it, you can unlock many different props to personalize Bruce Wayne's lair. Well, one of these props seems to feature Clayface himself. But in case that illustration isn't enough to convince you that TT Games is paying homage to Basil Karlo....

Then maybe this poster featuring Basil Karlo will do the trick. The iconic actor is the star of a movie called "The Terror", which is very fitting.

While gliding through the streets of Gotham, players can spot a huge pool hall called "QBall". In the comic book world, Q-Ball is a small-time supervillain who acts as the leader of The Pool Hall Gang.

In the source material, Dragoncat is a small-time DC villain who works as a karate instructor and looks to recruit students for his gang. It seems he's up to no good in LEGO Batman: Legacy of the Dark Knight, either, as players can spot marketing material for his dojo.

Phantasm is perhaps best known for being the main antagonist of the 1993 animated film Batman: Mask of the Phantasm. Unfortunately for the Dark Knight, the villain didn't stay buried, as there are many nods to her in LEGO Batman: Legacy of the Dark Knight.

That includes a haunting nod to fictional musical The Phantasm of the Opera. We would pay to see that on stage!

Last, but certainly not least, you can see posters promoting Cosmo Krank Toys, a company owned by the supervillain Toymaker in the 2004 animated series The Batman. A neat little nod to an overlooked part of the Caped Crusader's iconic history.

You can find the Mad Hatter's hideout

There's a story mission in LEGO Batman: Legacy of the Dark Knight where you have to venture inside Ace Chemicals, and there's something very interesting awaiting you there. There are two hidden areas in this location; the first one is locked behind a puzzle, which is completely optional. If you're successfully able to access it, you can see a red table with a teapot and two teacups on top (as seen in the image above).

The second hidden area in the level features many teddy bears having a tea party. Funnily enough, Batman can also participate in this event. Putting these two locations together, it's clear that the infamous Batman villain, the Mad Hatter, was using the Ace Chemicals building as his personal hideout. Furthermore, an unlockable Batcave prop also references Jervis Tetch.

Other iconic DC landmarks, such as Keystone, Smallville, and Blüdhaven, are mentioned

LEGO Batman: Legacy of the Dark Knight takes place entirely within Gotham City. However, that's not to say there aren't any references to other iconic DC locations. As seen in the image above, you can find a factory named "Keystone Industries". Well, Keystone City is better known for being the home of the Flash.

Similarly, you can find a billboard that mentions Superman's childhood town, Smallville. Interestingly enough, this particular artwork also appears to reference the live-action Smallville series due to the mention of "Gough & Millar's". After all, Alfred Gough and Miles Millar were the series' original showrunners.

When Batman and Nightwing are busy keeping the streets of Gotham City safe, the Dark Knight gives an interesting suggestion to his apprentice, "Have you thought about patrolling Blüdhaven? I'm sure they'd appreciate the help." In the comic book world, Nightwing acts as Blüdhaven's protector, so it seems this iteration of the character will eventually follow the same path.

You can find SpongeBob's house and a UFO in Carmine Falcone's hideout

Leave it to a kid-friendly game to reference a kid-friendly cartoon. When you're exploring Carmine Falcone's hideout in LEGO Batman: Legacy of the Dark Knight, you'll find yourself in an underwater area that hides many Easter eggs (some of which we'll discuss later in this post). One of these hidden secrets is the appearance of SpongeBob and Squidward's houses, made entirely with LEGO (as seen in the video above).

Interestingly, a UFO also lies hidden underwater. Could this be our very first indication that Darkseid or Starro are coming to invade us? Perhaps a future DLC could give us an answer.

There are multiple nods to the Batman: Arkham franchise

LEGO Batman: Legacy of the Dark Knight features an entire section dedicated to paying homage to Batman: Arkham Asylum. However, outside of that (amazing) sequence, there are also plenty of references to Rocksteady's acclaimed saga. One of these nods (pictured above) is the appearance of those creepy Joker figures with TVs for heads. Furthermore, the screen displays the Arkham logo when the player interacts with the figure.

The biggest Easter egg in Batman: Arkham Asylum was a hidden room that featured blueprints for Batman: Arkham City, the second entry in Rocksteady's franchise. Well, that very same blueprint can also be seen in LEGO Batman: Legacy of the Dark Knight.

Players are also able to decorate the Batcave with a huge diorama of Arkham Asylum, as seen in the 2009 video game.

Constantine and Madame Xanadu make their presence felt

Remember how we mentioned Carmine Falcone's hideout features a SpongeBob Easter egg? Well, the fun didn't stop there. There's an area where the path divides into three. One of them goes straight to Carmine's office. Another one leads to Club Constantine, which is a clear reference to DC's iconic antihero John Constantine.

The third and final path takes you to Xanadu's Inn, a hotel meant to reference DC's sorceress Madame Xanadu. Unfortunately, players aren't able to access either Club Constantine or Xanadu's Inn, but these were some neat Easter eggs nonetheless.

Iconic DC heroes like Black Canary, Green Arrow, Zatara, and Mister Terrific are here... kind of

Black Canary's powers make her the ideal candidate to be the frontwoman of a band, and that's exactly what happened in the comic book world. To commemorate this comic book run, players can see a reference to the heroine's band thanks to posters pasted on walls all around Gotham.

While we're on the note of references to other big DC heroes, we need to talk about Michael Holt. While Mister Terrific doesn't have a poster like Black Canary, a nod to his name can be spotted in multiple graffiti scattered around the City.

Another superhero referenced in LEGO Batman: Legacy of the Dark Knight is Zatara, whose billboards promote an upcoming magic show.

As for the Green Arrow himself, we actually get to see him in a billboard for his company, Q-Corp (which likely stands for Queen Corporation).

Many real-life movies are referenced with iconic illustrations

Let's switch things up a bit and take a quick break from the DC Easter eggs (just for a moment). LEGO Batman: Legacy of the Dark Knight contains many posters that reference real-life movies. The image above is meant to depict Dune, except it has a slightly different name to avoid copyright issues.

But that font and poster are instantly recognizable! Speaking of which...

Jack Nicholson portrayed the Joker in Tim Burton's Batman, so it's only fitting that one of the movie posters depicts another of the actor's movies, The Shining. And perhaps its new title - The Smiling - is a nod to the Clown Prince of Crime.

The Iron Giant is also referenced, courtesy of this "The Metallic Giant" poster.

Outside of Gotham's theater, players will spot a poster meant to represent Indiana Jones, and another that references Police Academy.

Perhaps one of my personal favorites, a billboard in Gotham City promotes a musical called "Les Minifigures", which is a nod to Les Misérables.

Players can spot the Flintstones' iconic car during one of the game's main missions, which takes place inside a museum.

Law & Order? More like Lawn Order, according to LEGO Batman: Legacy of the Dark Knight.

Last, but certainly not least, we can also see a poster of the Jonah Hex movie inside Gotham's museum.

There are references to other iconic video games, like Resident Evil and Five Nights at Freddy's

When you enter Bat-Mite's shop, there's a chance that he'll say a very interesting (and funny) line in a low, raspy voice, "What are you buying?" Immediately after, he returns to his normal voice and says, "Phew, that one's hard on the vocal cords! No idea how he does it". By "he", Bat-Mite is referring to The Merchant in Resident Evil 4.

Who would have thought a LEGO game would have nods to a Resident Evil title?

While we're on the subject of video games (in this large video game article), it's also worth noting that players can find a reference to Five Nights at Freddy's during one of the main missions, as seen in the video above.

Interestingly enough, there is also graffiti that reads "Gotham Knights", which could be a nod to the Gotham Knights video game released in 2022. Let's also not forget The CW's Gotham Knights TV series that was also released during the same year.

Poking fun at some DCEU projects like Black Adam and Suicide Squad

The DCEU was Warner Bros.' first attempt to build an interconnected universe featuring some of the world's most iconic superheroes. Unfortunately, things didn't go according to plan, and a new, rebooted universe was born under James Gunn's DCU. So now that the dust has settled, it's the perfect opportunity to look back and poke a little bit of fun at some previous projects. Case in point, LEGO Batman: Legacy of the Dark Knight makes a joke about the Joker's look in 2016's Suicide Squad, as seen in the video above.

Furthermore, whenever Batman sits on a throne, there's a chance he'll say, "The hierarchy of power in Gotham is about to change," which is a nod to the phrase Dwayne Johnson used to promote his Black Adam DCEU movie.

Locations from Matt Reeves' The Batman and Christopher Nolan's The Dark Knight trilogy are brought to life

There was a time when movie tie-in video games were a thing. These titles aimed to recreate the events of a theatrical film while allowing players to explore the landmarks seen on the big screen. Those days may be long gone now, but LEGO Batman: Legacy of the Dark Knight still lets us explore iconic landmarks from Batman movies. As seen in the image above, players can find the La Couronne Hotel, which is where Oz Cobb makes his new home in the finale of The Penguin HBO Max miniseries.

There's also a Wayne Enterprises building that heavily resembles the one seen in Christopher Nolan's Batman Begins, even featuring the train that runs through it.

If this hospital seems familiar, it's because it is a recreation of the one featured in The Dark Knight. You know the iconic one that Heath Ledger's Joker blew up in one of the 2008 movie's most memorable moments.

A "44 Below" sign is also visible in one of the game's main missions, which is a reference to Carmine Falcone's Club in Matt Reeves' The Batman.

Now, I know this isn't a "location" per se, but since we've been talking about The Batman, it's important to note that you can find posters nodding to Peter Sarsgaard's character, the corrupt district attorney Gil Colson.

An iconic moment from Batman (1966) is recreated, and actors are paid homage

Batman 1966 is very whimsical and even funny for an adaptation of the Caped Crusader. Perhaps one of the most iconic moments of the movie is when Batman uses Shark Repellent Bat-Spray to defeat a shark. So, of course, LEGO Batman: Legacy of the Dark Knight had to recreate such a sequence, as seen in the image above.

While we're on the subject of Batman 1966, it's worth pointing out that there's a store in TT Games' title called "Romero Grocery: Shopping with a smile." This is a reference to Cesar Romero, who portrayed the Joker in the movie and the 1966 series.

A touching tribute to Kevin Conroy

When talking about Batman, it's impossible not to think of Kevin Conroy. The legendary actor was known for lending his voice to DC's most popular hero across a multitude of projects. In fact, it is unanimously agreed that his portrayal of the character is one of the most iconic ever, as he defined what Batman should sound like.

Unfortunately, Conroy passed away in 2022. So, to honor him, LEGO Batman: Legacy of the Dark Knight includes a touching tribute that reads: "After hours with Conroy, the voice of Gotham's Night." Years later, the beloved actor is still recognized as the voice of Gotham's Knight, and it's a joy to see.

The many companies and buildings scattered across Gotham City

This rendition of Gotham City is absolutely massive, so it was bound to be filled with buildings that reference some of DC's most iconic companies, characters, and comic book writers. Case in point: the image above shows a "Meyer + Hayes" factory. This is a reference to Meyer and Hayes, a structural engineering company in the Gotham (2014) live-action show that employed Jeremiah Valeska.

Frank Miller and Alan Moore are two of the most popular and beloved DC comic book writers, which is why their names can be seen on the building above.

In the DCU, Alex Sartorius was the owner of Sartorius Labs, the very same place where he became Doctor Phosphorus after being unwillingly placed in a nuclear chamber. In LEGO Batman: Legacy of the Dark Knight, we see a similar facility, except it is called Sartorius Co.

Zucco Finance is a nod to Tony Zucco, the same man who was responsible for the death of Dick Grayson's parents in the comic book world.

Everett Oils is a reference to Will Everett, who's better known as the superhero Amazing-Man.

NygmaTech is the name of the company founded by Jim Carrey's Riddler in Batman Forever.

Q-Corp could be a reference to Queen Industries, the company run by Green Arrow. The logo's green color palette supports this theory, as does the target symbol inside the letter Q. Furthermore, we also have what appears to be a look at Oliver Queen himself.

S.T.A.R. Labs is a prominent location in the DC comic book universe and is also known as the headquarters of Barry Allen in The Flash TV series.

In the source material, Kord Industries was founded by Ted Kord, better known as the second iteration of the Blue Beetle.

Batman's creation date is hidden in the game model

You'll have to look very hard for this one. LEGO Batman: Legacy of the Dark Knight is filled with an immense amount of detail. Case in point, you can see what appears to be a serial number on the Dark Knight's arm. The number printed, however, is no coincidence.

Batman's first-ever comic book appearance took place in Detective Comics No. 27, which was released in 1939. Funnily enough, the hero's "serial number" in LEGO Batman: Legacy of the Dark Knight is 19-39.

The Gray Ghost recreates iconic Batman moments

We, as audiences, are often times inspired by the actions of superheroes like Batman. Similarly, a young Bruce Wayne looked up to the Gray Ghost, a fictional hero who appeared in TV shows. The opening sequence of LEGO Batman: Legacy of the Dark Knight sees Bruce dressing up as the Gray Ghost (as seen above), reminding us how much the character means to him. However, this isn't the only time we ever see this fictional hero throughout the game.

Scattered through Gotham City are many references to The Gray Ghost. The image above showcases him in a painting recreating the first-ever Batman Comic book, Detective Comics No. 27, playing with the idea that he and Batman represent the exact same thing. Similarly, we can also see his name in newspapers.

There's also a mural where The Gray Ghost recreates that one iconic The Dark Knight poster, where a building in the background has a flaming Batsymbol. Additionally, there are Gray Ghost posters that depict him sitting on a gargoyle, mimicking a classic Batman pose - perhaps even a nod to the Arkham City poster in which Batman is doing that exact pose.

The many comic book nods hidden in the game

As was to be expected, there are multiple comic book references hidden in LEGO Batman: Legacy of the Dark Knight. One of Gotham's most iconic reporters and journalists, Vicki Vale, can be seen in multiple billboards across the city, as shown in the image above. Furthermore, there's also the mention of Alexander Knox, who is a reporter aiding Vicki in the Batman (1989) movie.

While you unfortunately can't visit the Blackgate prison in LEGO Batman: Legacy of the Dark Knight, you can still see references to this penitentiary in the game, as shown above.

LEGO Batman: Legacy of the Dark Knight features a level that takes place inside the museum, where you're able to, quite literally, press a button and appreciate art pieces. Well, one of these pieces is none other than the recreation of Frank Miller's The Dark Knight Returns comic book cover, except it's made with LEGO bricks. Truly, the epitome of art.

This may be a bit of a reach, but I'd like to think that TT Games wanted to reference DC's Absolute Universe with the billboard showcased above.

There are many flyers of a band called Great Frog in LEGO Batman: Legacy of the Dark Knight. If this name sounds familiar, it is because this band was created by Teen Titans member, Roy Harper (AKA Speedy), in the comic book world.

Last, but certainly not least, you can also spot nods to the circus Dick Grayson and his parents performed in before tragedy struck.

Before we close things out with the very last section of Easter eggs and secrets, it's important to note that there will be some minor spoilers for LEGO Batman: Legacy of the Dark Knight ahead. If you don't want any surprise supervillain appearances ruined for you, it's best to turn away now.

Still here? Great, then let's discuss how the game foreshadowed the involvement of key antagonistic players during its main campaign well ahead of time.

LEGO Batman: Legacy of the Dark Knight foreshadows the appearance of many of its villains ahead of time

LEGO Batman: Legacy of the Dark Knight features the surprise appearance of many villains during its main campaign. However, some of these surprises can be spoiled ahead of time thanks to the many pieces of graffiti found within the game. In the image above, we can see Killer Croc's design, even before his side quest begins.

Scarecrow can be seen on an in-game poster, which features the villain's classic mask design. Of course, that is also sitting right beside posters that feature "Why So Serious?" - the iconic catchphrase of Heath Ledger's Joker in The Dark Knight.

Newspapers spoil the appearance of Clock King, who makes a brief cameo in the game.

Poison Ivy's involvement in the story is teased ahead of time, thanks again to the newspapers scattered across the city.

Despite not having a major role in the game, players can spot nods to Solomon Grundy before his quick cameo.

There were many Easter eggs featuring Calendar Man in the Batman: Arkham franchise, so it's only fair that it happens here as well.

LEGO Batman: Legacy of the Dark Knight is a huge game, so we most certainly missed some Easter eggs and secrets. Did you spot anything else out of the ordinary? Let us know on our social media pages on Bluesky, Instagram, and Twitter.

LEGO Batman: Legacy of the Dark Knight is out now on PlayStation 5, Xbox Series X|S, and PC.
