LEGO is steadily assembling its Transformers roster, adding the first Decepticon to its line-up with a G1 Transformers Soundwave set due out on 4 August, which can not only transform into a cassette player, but also comes with the character’s miniature transformable companions, Ravage and Laserbeak.



Marking the third Transformers build of its kind, following 2022’s LEGO Optimus Prime and last year’s LEGO Bumblebee, the LEGO Soundwave (set 10358) marks multiple firsts for the brand, as not only is it the first Decepticon set, it is also the first to feature companions, and the first to include voice playback, with an included “play” button on the model’s chest that recites Soundwave’s iconic lines when pressed.
Much like the previous two builds, the set will be targeted at adult collectors, comprising 1,505 pieces and measuring 13 inches (33cm) tall in robot mode, making it almost the same height as the LEGO Optimus Prime build. The main Soundwave figure, alongside the two companions, will all be transformable into their respective cassette player and cassette tape modes without needing to be disassembled and rebuilt.

The build will also feature additional accessories like cassettes, a rocket pod, alongside a laser blaster and a dart. The aforementioned sound brick piece also recites five different catchphrases and sound effects when activated, including Soundwave’s iconic lines like “Soundwave superior” and “Danger, Autobots detected”.
As a package, the LEGO Soundwave set presents perhaps the most comprehensive package in the line-up to date, as buyers are essentially getting three Transformers figures in one. The look of the build is also bound to delight fans of the now-retro G1 robot designs, offering an almost one-to-one replica of how the character appeared in 1986’s The Transformers: The Movie. The build will also feature knee articulation this time around, a feature sorely missing in the previous two sets, enabling collectors to display the figure in more dynamic poses.
The LEGO Transformers Soundwave set will launch on 4 August 2025 exclusively on the LEGO Store, and will be priced at S$259.90.
