If you’re deciding which LEGO Icons Transformers set to buy first, this page is here to save you from a raw marketplace search and give you a collector-first answer. GeekSerious adds the context that a vendor feed does not: which set is the classic G1 centerpiece, which one is the shortest build, and which one makes the most sense only after you already have the first two. If you want to keep going after this comparison, our Transformers tag page and Generation 1 Transformers checklist are the best next stops.

LEGO 10302 Optimus Prime

Pick this if: you want the classic G1 Autobot leader as your first LEGO Transformers centerpiece.
Optimus Prime is the obvious starting point because it is the icon most collectors picture first. LEGO’s official product page says the 1,508-piece set converts between robot and truck modes without rebuilding, and the robot stands over 13.5 inches tall. It also comes with a display plaque, so it works as a shelf model even if you never switch modes often.
For a first purchase, Optimus gives you the strongest “this is Transformers” payoff. It is the set that best anchors a LEGO Icons Transformers display, and it pairs naturally with a G1-focused collection. If you are building out that era, GeekSerious also keeps a Generation 1 Transformers checklist that helps place the character in context.
The tradeoff is simple: this is the biggest of the three by piece count, so it is not the lightest entry point if you want the quickest shelf win. But if you want the classic leader first, this is the one to open.
LEGO 10338 Bumblebee

Pick this if: you want the shortest build of the three.
Bumblebee is the cleanest first build if your main goal is a satisfying display piece without committing to the largest box. LEGO’s page says the 950-piece set converts “from Autobot to vehicle mode,” the robot stands over 9.5 inches tall, and it includes a display plaque. That lower piece count makes it the shortest build here.
LEGO also describes Bumblebee as built “maintaining the same scale as the LEGO TRANSFORMERS Optimus Prime set,” which is useful if you want the two Autobots to sit together as a matched pair. The practical reason to start here is still the same: at 950 pieces it is the shortest build of the three.
It is still an 18+ display model, so this is not a kid-oriented starter set. But for an adult fan who wants the shortest first build in the line, Bumblebee is the pick.
LEGO 10358 Soundwave

Pick this if: you already own Optimus Prime and Bumblebee and want the Decepticon that completes the trio.
Soundwave is the set for the fan who is past the “which one first?” stage and is filling the obvious gap in the lineup. LEGO’s official page lists 1,505 pieces, a robot height of over 13 inches, a display plaque, and the cassette companions Ravage and Laserbeak, which convert into cassettes that fit in Soundwave’s chest. That makes it the most collection-specific pick here.
The key difference is that Soundwave is not the same kind of first build as the other two. It is the payoff set for someone who wants a Decepticon opposite the two Autobots, and it adds more display story through the cassette-bay gimmick. If your shelf already has Optimus and Bumblebee, Soundwave is the natural next move.
It is also the most specialized choice for a first-time buyer. If you only want one LEGO Transformers set right now, the other two are better starting points. Soundwave makes the most sense when you are building a trio, not a solo shelf.
Buyer questions
Do they convert between robot and vehicle modes?
Optimus Prime converts between robot and truck modes without rebuilding, and Bumblebee converts “from Autobot to vehicle mode.” Soundwave’s Ravage and Laserbeak convert into cassettes that fit in his chest.
How do they look displayed together?
All three are LEGO Icons Transformers sets rated 18+, and each includes a display plaque. Bumblebee is also described by LEGO as maintaining the same scale as the LEGO TRANSFORMERS Optimus Prime set, which helps explain why those two read well together on a shelf.
Which is the longest build?
Optimus and Soundwave are the longer builds.
Is any of them a good gift for a younger fan?
LEGO rates all three 18+.
Which to buy
If you want the best first LEGO Icons Transformers set, start with Optimus Prime. It is the classic G1 centerpiece, it has the strongest “Transformers on your shelf” presence, and it gives you the most obvious anchor for the line.
Choose Bumblebee first if you care more about the shortest build than about the biggest icon. Choose Soundwave only if you are already planning a trio and want the Decepticon that completes the display. For most buyers, the order is clear: Optimus first, Bumblebee second, Soundwave last. Open the Amazon listing for the one that matches your shelf goal and build from there.
