We're sure we don't need to tell you that LEGOs are the best toys ever made. From epic pirate battles on the high seas to giant cityscapes, to knight castles—there's really no limit to what you can build with them. Recently, LEGO has branched out into the wonderful world of cartoons (with astounding success we might add). Ninjago, Chima and Nexo Knights take the world of LEGO and turn it into a compelling visual experience by making it a television show. These costumes? Well, they sort of take experience into the real world by transforming your child into one of their favorite LEGO characters from the show. 

Of course you can't forget about The LEGO Batman Movie where DC superheroes and villains became transformed into the LEGO men and women we all love! We now offer a LEGO Batman costume along with his sidekicks and the outlaws trying to cause havoc in Gotham City.

Let's also not forget that Emmet became the LEGO hero that we needed in The LEGO Movie, and Emmett and Lucy save the LEGO universe again in The LEGO Movie 2: The Second Part. Everything is awesome if you find your favorite LEGO Movie costumes for Halloween!

We carry a large selection of costumes and accessories based on your kid's favorite LEGO shows. With styles based on all of the Ninjago characters, as well as the Nexo Knights and the animals of Chima, and even as Batman and Joker! Whichever LEGO cartoon is your child's favorite, we'll make sure they're able to dress up as their favorite LEGO character for Halloween. Of course, you can't let them have all the fun by themselves. We even have adult LEGO costumes for you! It can become a whole family affair!

LEGO Costume Ideas

Remember the countless hours you used to spend playing with LEGOs? Gosh, there were so many different ways to play. Were you the type to ally with the Blacktron, or did you valiantly protect outer space as the Space Police? Did you favor the Forestmen, or did you build the great Black Knights Castle to extend your rule over the land? Did you sail the seas as the scoundrel pirate, Captain Redbeard? It’s easy to see how the LEGO name has stayed around as one of the best toy brands around. Of course, these days Ninjago and Nexo Knights are leading the charge and kids nowadays are just as excited about the new age of LEGO toys as adults were about the bricks of old! Being the costume experts that we are, we decided to delve into the costuming side of LEGO! We vigorously assembled set after set. We watched hours of Ninjago: Masters of Spinjitsu and we even tried building our own double-decker couch in preparation for our research into LEGO costume ideas. We came up with some great ideas to help your child get into the groove of their favorite LEGO mini-figures. Let’s begin by entering the mysterious land of Ninjago, where the classic building block toy meets the world of ninjas! Let’s explore all the great options there are for a very LEGO Halloween in this handy guide to LEGO costumes for kids.

LEGO Ninjago Costumes

Oh yeah, ninjas and LEGOs? Sign us up for that! In fact, sign everyone up for that. It’s one of the things that LEGO fans have wanted for years and Ninjago combines those two things into one awesome package. Each ninja has their own special powers and talents, so make sure to choose wisely when dressing your kid up as one of the heroic ninja masters. From the epic Green Ninja, Lloyd, to feisty master of water, Nya, so we’ll make sure to go through some of the best options below in our list of LEGO Ninjago costumes.

Boys Lloyd Ninjago Costume

Boys Lloyd Ninjago Costume

Tasked with restoring balance to the world, the Green Ninja is of legendary status! All the original ninjas were trying to prove themselves worthy of the mantle, but it turned out that Lloyd, the evil kid turned good, was the one for the job. It might take some pretty serious training to get your child fully versed with the Art of Spinjitsu, so you’d better be ready to take on the role of a wise sensei. Of course, you also better get him dressed up in this boy’s LEGO costume, which will have your child playing the role of the Green Ninja in no time.

Boys Ninjago Jay Costume

Boys Ninjago Jay Costume

If your child likes flashy moves, then Jay Walker is your guy! He’s the Elemental Master of Lightning, so when he heads into the fray, you can expect a lot of fireworks. His favorite weapon is tried and true nunchucks, so make sure you equip your child with a set of our toy nunchucks when you gear him up in this Jay blue Ninjago costume. You also might want to make sure you teach him a few sweet moves, since he may have to fight off the likes of Samukai, or even Master Chen.

Girls Ninjago Nya Costume

Girls Ninjago Nya Costume

Nya’s a girl who just can’t stand by while the bad guys wreak havoc. Even before she discovered her true potential as an Elemental Master of Water, she was masquerading as Samurai X to help the Ninjago crew out whenever her friends were in danger. Now, she’s mastered the ninja arts and she’s even got a brand new set of katanas to ward off any evil doers. If your girl is ready to be just like Nya, then it’s time to gear her up in this LEGO Ninjago costume, along with a set of our toy katanas. She’ll be ready to cut through villainy in no time!

Boys Kai Ninjago Costume

The resident hothead of the group, Kai not only acts impulsively, but he also actually wields the power of fire! That’s right, Kai is the Elemental Master of Fire and he has no problems using it to properly toast the baddies. If that sounds a little like your kid, then he might want to head out wearing this Kai Ninjago costume for kids. It’s based on his appearance from the TV series and will have him feeling fiery enough to take on a whole platoon of Skulkin warriors!

The mask has a blocky look and a bright red color scheme that perfectly reflects Kai’s go get ‘em attitude.

Every good ninja needs a ninja weapon! There are so many to choose from, so where do you even start?

Talk about ninja value!
