Two of the coolest building sets in the Lego Icons lineup are on sale for great prices at Amazon. Transformers fans can add the 1,508-piece Optimus Prime Lego figure to their collection for $157 (was $180). Based on the Autobot’s iconic Generation 1 appearance, Lego Optimus Prime is a 2-in-1 model that can be converted from robot to truck. Lego’s 950-piece Bumblebee figure has the same kind of 2-in-1 functionality, allowing fans to convert the fully assembled build from robot to car with a series of twists and folds. The Bumblebee Lego model is on sale for $72 (was $90), which matches Amazon’s best price yet.
In August, Lego launched a 1,505-piece Soundwave figure, its first Transformers Decepticon 2-in-1 model. Soundwave can convert into a retro cassette player, so it’s rather fitting this is the only one of the three Transformers Lego models with a speaker brick that plays lines of dialogue and sound effects. Soundwave arrived at major retailers in October, and despite selling for its full $190 MSRP, retailers have had a hard time keeping Soundwave on their shelves. Amazon just restocked this set on December 22. At the time of writing, only Amazon and Target have Lego Soundwave in stock; it’s on backorder at the Lego Store and is sold out at Best Buy and Walmart.
All three Transformers Lego sets were designed for adult collectors or experienced builders. You can read more about Optimus Prime, Bumblebee, and Soundwave below. We also included images of the robots converting into their alternate display modes. And if you want to watch Michael Bay’s blockbuster films while building, you can get the newly rereleased Transformers & Bumblebee 6-Film Steelbook 4K Collection for $79. Alternatively, the Transformers 7-Movie 4K Collection, which launched the same day, is available for only $53.

Optimus Prime is a highly detailed model of the Autobot leader’s G1-era design. With 19 points of articulation, you can create an wide range of poses by adjusting his limbs in robot mode. Lego’s detailed scale-model of the G1-era Optimus Prime is essentially a 13.5-inch action figure. You certainly don’t want to be rough with it, but it has more movable components than you’d normally expect with Lego thanks to its 2-in-1 design.
Switching from robot to truck mode and back again is a relatively straightforward process. At first, the switch might take you a couple minutes, but once you have the steps memorized, it’s possible to convert the build in less than a minute.
Beyond its ability to completely transform, Optimus has a suite of interactive features and accessories that make it one of the most dynamic builds in Lego’s lineup of collectible sets for adults. Brick-built replicas of the ion blaster and Energon axe can be attached to his hands. You can easily fasten or remove his jetpack and swap between two different waist panels. The dual windows covering his chest can be swung open to access the Matrix of Leadership artifact. It also comes with an Energon cube and an information plaque to display alongside the model.
Lego makes a ton of vehicle display models, so it’s pretty remarkable that Optimus Prime’s “secondary” truck mode looks good enough that you could mistake it as a vehicle that doesn’t transform into a robot. When displayed as a truck, Optimus is 10.5 x 4.5 x 5.5 inches.
Like many other Lego sets geared toward adults and collectors, Optimus Prime has a more complex build process than the average set. An ample variety of conventional bricks and unique piece types makes it a thoroughly rewarding set to construct. Depending on your experience with Lego sets of this size, it could take you anywhere from three to six hours to complete.

Bumblebee joined the Lego Icons collection in July 2024, and it took over a year before we saw a meaningful discount at a major retailer. While I’m sure Bumblebee fans would have liked a larger figure like Optimus or Soundwave, it’s nice that one of Lego’s 2-in-1 Transformers models is available for under $100. I’d argue it’s one of the coolest Lego sets for adults in its price range.
Bumblebee doesn’t have as many intricate details as the larger Optimus Prime and Soundwave models, but this 950-piece set is a wonderfully designed and authentic recreation of the Autobot’s G1-era look.
The 2-in-1 build can transform from robot to car. Bumblebee’s bright yellow vehicle resembles a Volkswagen Beetle from the 1980s. In car mode, Bumblebee is 8.5 inches long–not much smaller than Optimus in truck mode. Bumblebee’s robot mode measures 9.5 inches tall. He has articulated limbs to create dynamic poses.
Bumblebee’s accessories include a large, detachable ion blaster and jetpack. The display plaque connects to a small buildable stand and lists Bumblebee’s power stats.
$190
Soundwave is a 1,505-piece, 13-inch display model, so it’s roughly the same size as Optimus Prime in height and piece count.
Like the other two Transformers builds, Soundwave is based on his appearance during the G1 era. Instead of transforming into a vehicle, this 2-in-1 build can be converted into a cassette player. You can press Soundwave’s play button to hear dialogue and sound effects. The voice box is powered by three LR44 batteries, which are included with the set. If you want to have extras, a 6-pack of LR44 batteries is only $5 at Amazon.
Another unique aspect here is that there are buildable figures of Ravage and Laserbeak. And just like Soundwave, these smaller figures can transform. After converting Ravage and Laserbeak into cassettes, they can be stored inside Soundwave’s cassette deck.
A brick-built information plaque details Soundwave’s technical specifications (power statistics). A miniature cassette tape sits next to the reference card.
Soundwave launched August 1 as a timed Lego Store exclusive before releasing at major retailers on October 1.
