The X-Files Lego set is a wonderful bit of 90s sci-fi nostalgia

Millennials get a lot of flak for being overly nostalgic, but I don't think that's fair. When the modern-day world has nothing to offer us but AI slop, shrinkflation and a sad acceptance that we can't be bothered to do anything about global warming. It's easy to see why we yearn for the days of Pogs, the Backstreet Boys, and Saved by the Bell.

One area that we definitely had it good in the 90s was sci-fi, when legendary shows like Star Trek: The Next Generation, Stargate SG-1, and — of course — The X-Files ruled our TV screens long before the age of streaming services. You can relive those glory days of alien conspiracies, spooky happenings and cell phones the size of a brick with the Lego Ideas The X-Files set.

This 1478 piece set is essentially two dioramas crammed into a single display piece. The top of the model depicts a spinning UFO floating above one of those iconic coniferous forests that dominated 90s sci-fi. Why? Because — thanks to some generous tax credits — it was cheaper to shoot in Vancouver, so that's where they all flocked.

Beneath the woodland scene, though, is the real star of the show: Mulder's office, squirrelled away in the basement of the FBI's J. Edgar Hoover Building in Washington, D.C. This dingy little office is where Scully meets "Spooky Mulder", kicking off a glorious sci-fi odyssey that would last for eleven seasons (and two movies).

Mulder's dingy little base of operations has been stunningly recreated here, with both overt references and subtle nods that X-Files fans will appreciate. The iconic "I want to believe" poster adorns the wall, alongside photographs of crop circles and a newspaper clipping from a paper called "The Lone Brickman" — a nice nod to "The Lone Gunmen". There's even an actual X-File sitting on the desk, and a cute Lego spoof of the "Face on Mars", with a photo on the wall that shows a Lego head on the moon.

It's been a hot minute since I watched The X-Files (that DVD box set beside my TV is calling to me), but even so, I had a blast building my way down memory lane, remembering episodes as I assembled the diorama. I love the little touches, like the display cabinets filled with artifacts, the VHS tapes scattered around the office and the black oil spillage on the floor.

As with most Lego sets, the minifigures are half the joy. You get Mulder and Scully, obviously, with the dynamic duo of FBI agents both rocking flashlights (no smartphones with built-in lights back in the 90s). Mulder is wearing dark blue, while Scully is rocking an orangey brown suit, with both of them sporting an FBI badge.

Outside of the principal pair, you also get Skinner, Mr X, and the Cigarette Smoking Man. Mulder's partner-turned-nemesis Alex Krycek also gets a suitably devious-looking minifig. It's the gloves, they just make him look like a bad man (which, to be fair, he is). Finally, to ramp up the paranormal scale, we also get a pair of monster minifigs: a grey alien and Flukeman minifigures. The grey alien was a must-have, especially given the UFO floating atop this display piece, but the one-off monster of the week, Flukeman, felt like a weird choice.

Also, this John Doggett erasure will not stand. Sure, he could never replace Mulder, but Robert Patrick's seasons eight and nine run was excellent and he deserved a spot here.

And while I'm voicing minor gripes, the usual Lego FOMO tricks were in force with this set; if you pre-ordered, you got an exclusive gift set — Scully's Lab — free of charge. This extra little diorama isn't necessary, but it does feel like the collection is incomplete without it and it's not for sale separately, so you'll have to try your luck with eBay scalpers if you want it.

Speaking of Scully, Gillian Anderson has stated that after season 11 wrapped in 2018, she was done with the role. That wasn't entirely accurate, though, as she donned the lab gloves one more time for the Lego X-Files set advert. It's a short bit of fan service, but a nice touch, and, once again, it sparks those 90s neurons.

All these delicious Member Berries come at a price, though, and that's the price. This blast from the past will set you back $199 (£179 in the UK). That's no small chunk of change. But then again, anyone who wants this set is in their thirties or forties and can probably afford that outlay for the nostalgia trip. And look at it this way: when The X-Files debuted back in 1993, the price would only have been about $86.

I had a great time building the Lego X-Files set and if you're a fan of the series, you will too. Nostalgia often feels like a cheat code to our hearts, but there's nothing wrong with that. We deserve to remember the good times and the truth is that The X-Files was about as good as it ever got for sci-fi fans.

You can buy the Lego X-Files set now, available for $199/£179 from the Lego store.

Best space and sci-fi themed Halloween costumes for 2026

Are you stuck for an outfit this spooky season? We've got you covered with our round-up of the best space themed Halloween costumes. Let's face it, even if there aren't any haunted spaceships out there, the vastness of the void is enough to give us the chills.

From Aliens to Star Wars, these costumes are sure to make you stand out, get the conversation flowing and maybe even raise a chuckle or two. And if you're a regular convention-goer, many of these costumes can double as cosplay outfits.

If you're still struggling for inspiration, or want to put your own costume together from scratch, you can always check out the best lightsabers, best streaming services or the best Lego Star Wars and Lego Marvel sets for ideas.

The quick list

The best space and sci-fi themed Halloween costumes we recommend in 2026

The best overall

Aliens chestbuster crew costume

A wonderfully gruesome Halloween costume that's instantly recognizable

Price: $79.99 | Materials: Cotton/poly/latex | Available sizes: Small to XL | Color options: One color

Realistic
Officially licensed memorabilia
Just the t-shirt is enough
Trousers are not movie-accurate
Not suitable for those with a latex allergy

As sci-fi horror goes, it doesn't get more disturbing than Alien's infamous chestburster scene and now you can cosplay as one of the Nostromo's unfortunate crewmembers, complete with an alien emerging from your torso.

Admittedly, no one in the movie actually wore beige pants, so there's an inaccuracy there, which is odd given this is an officially licensed Alien costume. But the 3D chestburster, a wonderfully gruesome latex model attached to the outfit's t-shirt, more than makes up for that.

In fact, if you're in a hurry, you can forget about the rest of the costume and just slip on the t-shirt; between the creature on your chest and the Nostromo badge on your shoulder, there'll be no mistaking your outfit. And if you're looking for a couples costume, you can snag this Ellen Ripley jumpsuit.

The best for Star Wars fans

A Star Wars Jedi Outfit with and without hood and cloak.
Amazon

Jedi robes

A great Halloween and cosplay outfit for fans of the Star Wars saga.

Price: $74.99 to $89.99 | Materials: Cotton | Available sizes: Medium to 3XL, gender neutral design and fit | Color options: Brown/beige, white/beige, black

Cosplay outfit
Detailed design
Gender neutral fit
Expensive for a Halloween costume

This outfit may not bear the official Star Wars name but any fan of the saga will recognize it as the iconic robes of a Jedi, as worn by Obi-Wan Kenobi and virtually every light side wielder of the Force.

This cotton costume has plenty of detail and comes with a set of faux leather pouches, and they're unisex, so you can cosplay as whichever pre-Order 66 Jedi you want. Just add one of the best lightsabers.

But what's especially cool about this outfit is that it can be worn in a variety of ways. The tunic, trousers and cloak are all separate pieces, so you can leap into battle or slip the cloak over your head and lurk in a corner, looking all mysterious.

Those who've purchased this outfit praise its quality, in particular the thickness of the fabric. And if you lean more towards the Dark Side, there's a black Sith version as well.

The best for nostalgia

Captain Kirk shirt

For anyone with a soft spot for Star Trek: The Original Series.

Price: $49.80 - $58.59 | Materials : Polyester | Available sizes: Small to X-Large, men's only | Color options: Gold

Nostalgic
Simple and fuss-free
Create the whole crew
Embroidery could be better
Sizing can be tricky
Hand wash only

I used to love watching the Original Series with my Grandad on a weekend. I have no idea how old I was but I have fond memories of those times and the many hours spent trying to learn how to do the Vulcan salute. If you're a fan of the Original Series like me, or just the original of anything Sci-Fi, this might be the Halloween costume for you.

Captain Kirk's shirt is a super simple and fuss-free Halloween costume. People will instantly recognize the striking color and design as being that of Captain Kirk. Combining it with a pair of dark pants will really set this costume off.

One great thing about this item is that it's not only a great Halloween costume choice but also an officially licensed product, meaning it's trademarked and authentic — ideal for true Star Trek fans as an item they can keep and wear again and again. Plus, there is the option of creating the full crew with family or friends, with the women's Starfleet dresses also being available.

It's important to note that the product listing advises customers to look at the sizing chart, rather than ordering based on your known sizes. Some people found the fit to be right, while others had to return it and order another size. To avoid this, it's best to consult the size chart. Reviewers also mentioned that the embroidery can be hit and miss, especially around the emblem.

Regardless of this, I think, for the money, this is a decent Halloween costume that will spark memories for those who grew up with the Original Series.

The best for women

Princess Leia

One for the women — become a powerful princess for a day.

Price: $45.99 (with wig) | Materials: Cloth and PU leather | Available sizes: Small to 3X-large, women only | Color options: White

Full costume
Machine washable
Versatile costume
Cannot tumble dry
No reviews

This Princess Leia costume is a great option for any Halloween parties you might be attending this year. Whether you're a Star Wars fan or not, this outfit is a classic and allows you to feel like a powerful princess while you're wearing it. You can purchase it with and without the wig — if you buy the wig, there will be no mistaking who you are. It's a simple outfit yet one that everyone will recognize. The attention to detail is good, with it mimicking the outfit worn in the films pretty accurately. So, even if you don't purchase the wig, most people will probably guess who you are dressed up as.

Made from cloth and synthetic leather, this costume can be worn by vegans too, so there are no exclusions there. It comes with the belt and, apparently, true-to-size sizing. However, there are no customer reviews for us to be sure whether this is the case or not. It may be a good idea to use the measurements provided to get the right size for you.

The best thing about dressing up as Princess Leia on Halloween? You have a fancy dress outfit ready for other parties, too. Plus, if you're into cosplay, you have your next outfit sorted. And, while some fancy dress outfits are a pain to clean, this costume is machine washable so there's no faff with hand washing. The only thing to be aware of is that it's not suitable for the tumble dryer.

Overall, this is a recognizable and classic choice for Halloween this year. However, if this doesn't feel like the right costume choice for you, you could consider other options in this guide.

The best comedy

Inflatable Spaceship Costume

A brilliantly silly costume that's sure to grab everyone's attention

Price: $41.99 | Materials: Polyester | Available sizes: Adult | Color options: None

Looks excellent
Sure to make people laugh
Auto-inflates
Requires batteries or powerbank
May need help putting it on

This inflatable spaceship costume takes the famously cheesy fake leg outfit and updates it to the space age. Put it on, let it inflate and everyone will think you're literally flying around the room!

Okay, maybe they won't be entirely convinced, but this ridiculous costume, with its dangling inflatable 'legs', will get you plenty of laughs and attention. Why not combine it with the kid-friendly rocket costume to create a family costume?

It inflates and stays inflated via the use of a battery pack, though some purchasers report you can also use a power bank. Its Amazon reviews are mostly positive, with the only real gripe being that you may need help to put it on.

The best villain

Darth Vader

A classic villain costume that kids will love to show off.

Price: $29.99 | Materials: Poly jersey and plastic | Available sizes: X-Small to Large, children's only | Color options: One color, black

Instantly recognisable
Full costume at a bargain price
Good quality
Sizing runs small
Chest padding received mixed reviews
Only available in children's sizes

Another recognisable costume that needs no introduction. What child doesn't love dressing up as the bad guy? And you can't get more iconic than Darth Vader.

This Darth Vader outfit comes with the helmet, cape, boots and gloves, so there's no need for further shopping with your little one to complete their outfit. Should they find the helmet uncomfortable to wear, for example, an added benefit is that the helmet, gloves and cape are detachable should your child decide they prefer to wear it without.

The reviews note it's good quality and durable, with many children enjoying wearing this costume. Durability is definitely something you need for little ones so this gets a thumbs up. One review noted that, although the material was good quality, it was thin, so this might be something to bear in mind if you live in a colder climate. Some reviews stated that the costume was large in places, such as the gloves and cape, whereas others say the sizing was spot on, or even on the smaller side. This may be down to personal preference but it seems getting the right size might prove difficult.

While being a pretty cool Halloween choice for kids, it's also an officially licensed product from Marvel. There's some jealousy that this isn't available in adult sizes...

Altogether, this is a great kid's costume for Halloween that's beyond reasonably priced. You can't go wrong.

The best for young kids

Rocket costume

The perfect space-themed costume for your little ones.

Price: $32.99 | Materials: Polyester | Available sizes: Small to X-Large, children's only | Color options: One color

Simple to put on
Quirky and cute
Lightweight material
Need to source silver shirt
Slightly pricey

This rocket costume will light up your child's Halloween. Whether you've got a girl or a boy, this costume is unisex in sizing and design, so it can be enjoyed by any little one. It's super simple to get your little one ready for Halloween — the rocket slides over their clothes. That's it. However, something to note is that it doesn't come with the silver shirt, so you would need to source this yourself if you want to match the rocket. That's the same for the bottoms — you would need to source orange bottoms to match the flames, if that's what you wanted to do.

Users note the material is good quality and that it's lightweight, meaning it doesn't interrupt playtime. One reviewer noted that it arrived crinkled after being in the packaging and advised removing it and letting it hang for a while before wearing. Another reviewer noted they bought it for their older child but the sizing was tight. Therefore, it seems this is a costume best suited to younger children, probably toddlers or up to five or six years old.

One of the benefits of buying a space-themed Halloween costume is that it's not only relevant at Halloween. Your child can enjoy this costume throughout the year or even use it during playtime with friends. There are multiple uses for it and that somewhat counteracts the slightly higher price for effectively an incomplete outfit (as you have to source the top and trousers yourself).

Overall, this is a quirky and cute alternative to Halloween for your little ones to enjoy, especially if they are interested in space.

Alongside the usual interstellar shenanigans, Marvel's Guardians of the Galaxy Vol. 3 revealed the origin story of Rocket Raccoon.
