Red Bricks are the cosmetic collectibles worth hunting in LEGO Batman: Legacy of the Dark Knight. There are 18 total: 12 hidden across story missions, and 6 purchasable from Bat-Mite's shop in the Batcave. Each one you collect unlocks a new color scheme for all your suits and vehicles, applied any time through the cosmetic menu. None of them affect gameplay stats, but completionists and trophy hunters will want every single one.
What are Red Bricks and how do you use them?
Red Bricks (also called Modifier Bricks) are purely cosmetic collectibles. Collecting one unlocks a new color palette applied to suits and vehicles. To activate a brick you've collected, open the character menu, select your character, choose Suit Options, pick the suit you want to recolor, then select Red Brick Options and choose your preferred palette.
The mission-based bricks each require solving a small puzzle. The shop bricks just need studs. Both types end up in the same menu.
Red Bricks from Bat-Mite's shop rotate randomly, but only cycle to the next item after you purchase the current one. Some bricks won't appear in the shop until after you finish the main campaign and unlock all companions.
All mission Red Brick locations
Below is a full reference table, followed by detailed puzzle walkthroughs for every mission brick.
Ninja Red Brick (Infiltration mission)
After building the giant crossbow to cross the cliff gap, walk the rope and shimmy along the building until you pull a ninja off the edge. Instead of climbing up to continue the main path, keep shimmying right and follow the gold studs. Drop down to a lower castle wall and crawl through the entryway.
Inside, you'll find four pressure plates and two large ninja statues. Press all four plates simultaneously to raise the torches. Grab the two stacks of books in the room and place them on two of the plates. Stand Bruce on a third plate and Talia will take the fourth. The Ninja Red Brick pops up between the statues. Color scheme: light grey with green accents.
Nautical Red Brick (New Beginnings / Docks mission)
Play through almost to the end. When you hit the "Build something to reach Flass" objective, look left of the warehouse where Flass is hiding. There's a small grey building with caution signage. Grapple up to the gold studs and drop through the open skylight. The Nautical Red Brick is sitting in the corner of the room. Color scheme: white with light and dark blue accents.

Filthy Rich Red Brick (Carmine Falcone / Iceberg Lounge mission)
After crossing the dance floor and completing the "Speak to Flass" objective, head to the back room with the window overlooking the dance floor. You'll see a vault with the brick floating behind the bars and a tumbler with three number slots. The middle number (9) is fixed.
To find the two-digit code: flip over the white LEGO brick on the red couch (it reads "X96", so the right digit is 6). Then check the side room that opens after talking to Flass. A brick on the floor reads "59X", confirming the left digit is 5. Enter 596 into the tumblers to open the vault and collect the Filthy Rich Red Brick. Color scheme: green with dark green accents.
The two code bricks are placed face-down. You need to interact with each one to flip it over and read the number. Easy to walk right past them.
Toxic Waste Red Brick (The Red Hood Gang / ACE Chemicals mission)
Progress until the "Follow the bears" objective, then continue until you reach a hallway with red ooze pipes on the right and blue ooze pipes on the left. Don't use the door. Instead, find a crawl tunnel on the right side of the room.
On the other side, a clear pipe holds the brick in the center with an ooze blockage. Use Batman to pull the hatch off the wall on the right, then use Gordon's goo gun to plug the green ooze leak left of the brick. This pushes the brick right to the next stoppage and creates another leak. Plug that one too, then grapple through the hatch. The Toxic Waste Red Brick sits on a grate on the other side. Color scheme: yellow with light and dark green accents.
Feline Red Brick (Mimes / Shreck's Department Store mission)
At the "Find a way past the doors" objective, you'll be in a store courtyard with a red Schrecks sign, a blue Pets sign, and a green Gadgets sign. Head to the Gadgets section.
Interact with the wire on the ground and plug it into the TV to activate a maze mini-game. You appear as a green cat in the top left. Navigate the cat to the red dot at the bottom (avoid the orange dog, collect blue studs for bonus cash). Reaching the end causes the TV to explode, dropping the Feline Red Brick. Color scheme: off-white with dark grey accents.
Gothic Red Brick (The Penguin / Arctic World mission)
After crawling through a duct early in the level, you'll reach a room with a Batmobile ride and a Duck vehicle schematic on the wall. Throw a Batarang at the collectible yellow duck above the Penguin poster, then crawl through the grate with Batman and Catwoman.
The brick sits behind a cage. Use Catwoman to cut the glass protecting the red umbrella, grab it, and swap it into the machine in the middle of the room (replacing the yellow umbrella). Whip the coil on the right side until the umbrella tip points at the brick (matching the floor paint diagram), then jump on the left button to blow the cage open. Collect the Gothic Red Brick. Color scheme: light purple with dark purple and yellow accents.
Artist Red Brick (Flugelheim / The Party Man mission)
Progress to the "Disable the security gate" objective and head down the right hallway to get the bust. Summon Catwoman's cat and enter the grate as normal, press the security button, but don't leave. As the cat, look for a climbable path upward above the security guard's computer. Follow the gold studs up and through a hatch. The Artist Red Brick is right there. Collect it as the cat and return to Catwoman. Color scheme: red with blue and yellow accents.
Showbiz Red Brick (Joker / The Big Dukeroo mission)
This is a sandbox level. The target building sits between the jungle float (2nd) and the castle float (3rd), with a yellow flowerbed on its window and Joker vans parked below on the right side of the street. Grapple up with Catwoman and cut the window open.
Inside, summon Catwoman's cat and jump onto the table on the right, then onto the TV. Swap to Batman and move the TV over to the bookcase. Swap back to Catwoman and jump the cat across to the bookshelf, then through the cat door. The Showbiz Red Brick is on a shelf on the other side. Color scheme: light yellow with yellow and white accents.
Clown Red Brick (Two-Face / Haly's Circus mission)
After defeating all enemies on the tent floor during the Robin training section, the objective switches to "Find a way to reach the bomb." Jump onto the strength test machine on the floor. Three targets appear. Hit all three with Robin's Birdarang and the Clown Red Brick pops out. Color scheme: white with blue and red accents.
Power Plant Red Brick (Kite Man / Power Plants mission)
This is another sandbox level and you can grab the brick immediately. Swap to Robin and find the walkway near the killer plant that leads to a door he can pry open. Inside, shoot Robin's crossbow at the fuse on the fan and the generator on the wall to power them up.
Swap to Batman and have him jump into the fan (he'll float mid-air). Swap back to Robin and use his stick in the left-side machine to close the grate door, letting Batman float above it, then re-open it. Batman lands in front of the Power Plant Red Brick. Color scheme: blue with dark blue and yellow accents.
Flower Power Red Brick (Poison Ivy / Botanical Gardens mission)
At the "Find Dr. Isley's lab" objective, reach the end of the room full of explosive plants. A small greenhouse sits right next to the door to the rest of the mission. Destroy the junk blocking it and go inside.
The room has a machine that grows hybrid plants using two inputs on either side of the brick. Place the green fern on the left and the red rose on the right. The plant grows in the middle, the plastic bubble releases, and you collect the Flower Power Red Brick. Color scheme: green with pink and dark green accents.
Fire Breather Red Brick (Firefly / Knight at the Museum mission)
After Firefly escapes through a door, look right and enter the planetarium. A large globe sits in the center with lights shining on it, and planet displays line the walls. Mars is the only planet with a gold border.
Change all four lights shining on the globe to Mars. Once all four sides are red, the globe opens and drops the Fire Breather Red Brick. Color scheme: orange with red accents.

All Bat-Mite shop Red Bricks
Bat-Mite's shop unlocks early in the game inside the Batcave. The podium near the entrance sells specialty suits and Red Bricks. The bricks rotate randomly but only cycle after you purchase the current item on the podium. Some bricks are locked behind post-game companion unlocks.
The shop bricks won't all appear at once. You need to buy out the costumes on that podium to cycle through to the next brick. Budget your studs accordingly if you want all six without grinding.
If you need to farm studs efficiently before hitting the shop, check out the full LEGO Batman: Legacy of the Dark Knight strategy guides for stud farming tips and other collectible guides.
Are Red Bricks tied to trophies or achievements?
If you're going for full completion, Red Bricks are part of the collectible checklist. For a complete breakdown of what counts toward 100% and the Platinum, see the LEGO Batman: The Dark Knight trophy list and achievements guide. Collecting all Red Bricks is likely required for full completion, so treat the mission bricks as must-grab items on your first playthrough whenever the level allows it.
For players deciding whether to go for everything in one run, the main campaign takes around 15 hours, but full completion pushes well past that. Check the how long to beat LEGO Batman: Legacy of the Dark Knight guide to plan your time before committing to a completionist run.
