LEGO.com has officially unveiled one of the most anticipated droids in a brick-built format—the LEGO Star Wars K2SO (75434) set.
Announced during Star Wars Celebration Tokyo, this stunning large-scale display set pays tribute to the snarky yet loyal droid that stole the show in Rogue One and will return in Andor Season 2.
This impressive droid will be landing at LEGO.com and LEGO Stores starting August 1, 2025, for $89.99 USD / £79.99 GBP / €89.99 EUR. With 845 pieces, this buildable LEGO Star Wars K2SO promises to bring sass, scale, and Star Wars nostalgia all in one package.
What You Need to Know About the LEGO Star Wars K2SO Set
Who Is K-2SO and Why Is This Set a Big Deal?
If you’re newer to the galaxy far, far away, K-2SO (voiced by Alan Tudyk) is a reprogrammed Imperial security droid turned Rebel ally. He quickly became a fan favorite thanks to his dry humor, no-nonsense attitude, and ultimate act of sacrifice in Rogue One: A Star Wars Story.
This is not the first time that we have had a LEGO Star Wars K2SO set – he was last seen in minifig form in 2016’s Krennic’s Imperial Shuttle set. But this version is a full-on, large-scale collectible perfect for fans who want a serious centerpiece.
What’s in the Box of the LEGO Star Wars K2SO Set? Buildable Details You’ll Love
LEGO Star Wars 75434 K2SO is more than just a model—it’s a fully articulated poseable display figure designed with collectors in mind.
Here’s what you get:
- A large-scale brick-built LEGO Star Wars K2SO featuring posable arms and head to help you recreate his signature stance or mix it up for dynamic displays.
- A sleek display stand with an information plaque, giving it that UCS-style presentation fans love.
- A bonus standard LEGO Star Wars K2SO minifigure, great for play or to complement your existing minifig collection.
At just under 850 pieces, the build strikes a nice balance between detail and accessibility. It’s rated 10+, making it a great choice for both younger fans and older builders looking for a satisfying weekend project.
Design Notes – True to the Source
From the angular chest plate to the elongated limbs, this LEGO Star Wars K2SO model nails the mechanical proportions seen in the live-action series. The color scheme—mostly black and dark gray with subtle highlights—faithfully reflects his onscreen appearance. The design team clearly worked to preserve the character’s unique silhouette, making it easily recognizable on any display shelf.
While the model doesn’t talk (sorry, no sarcastic one-liners), the included minifig and plaque help tell his story, making it feel like a small slice of Andor or Rogue One in your LEGO room.
Where It Fits in the LEGO Star Wars Lineup
Following the success of similar droid models like R2-D2 (75308) and BD-1 (75335), the LEGO Star Wars K2SO’s addition feels like a natural—and long overdue—move. He’s part of a growing trend toward large, UCS-adjacent display sets that emphasize character likeness and poseability over play features.
If you already own the UCS-style R2 or buildable droids like D-O or the Probe Droid, K2SO is the next logical addition. And at $89.99, it’s one of the more affordable display builds of its scale.
