LEGO Set 10358-1 Transformers: Soundwave Alternate Builds – 3 Creative MOCs to Try

LEGO Set 10358-1 Transformers: Soundwave is already a display piece with serious personality—clean shaping, bold color blocking, and that unmistakable “retro-tech meets character model” vibe. But what really makes a set like this special is how well it invites experimentation. The moment you finish the official build, you start noticing all the reusable geometry: panels that can become hull plating, layered slopes that naturally suggest vehicle contours, and those distinctive accent colors that pop beautifully when you flip the design language into something new. It’s the kind of parts selection that can swing between “robotic” and “mechanical” with just a few structural choices—perfect for alternate builds.

With the right MOCs, 10358-1 becomes more than one iconic model. You can turn it into a compact sci-fi craft, push it into an upgraded character variant, or build an accessory-style display companion that feels like it belongs right next to the main set. Some builds are true alternate builds using only the parts in the box, while others are modifications that keep most of the set intact and add a small number of extra parts for details or stability. Either way, the result is the same: you get more shelf presence, more variety, and more reasons to keep this set on your desk instead of back in the box.
