Siege Colossus Transforming Battle Mecha — 4,002 Piece Mecha Building Set
Siege Colossus Transforming Battle Mecha is a transforming battle mecha designed around accuracy rather than play, and it shows in the part choices. It runs to 4,002 pieces and takes around 18+ hours to complete.
What You're Building
The battle warrior is built with fully detachable armour revealing the core structure beneath, an illuminated chest core and movable joints. The armour converts into a jet configuration.
Inside the Box
4,002 ABS bricks with consistent clutch power, sorted into numbered bags. A printed manual guides the build step by step. Every brick is compatible with the major building systems, so parts from an existing collection drop straight in. If a piece is missing or damaged, our spare-parts guarantee covers the replacement.
The Build
Rated expert, this is a large-scale build suited to dedicated builders ready for an extended, multi-session project. Expect roughly 18+ hours for a first pass at a steady pace. Working through the transforming battle mecha in stages keeps the bench manageable.

Customer Reviews
Overall rating: 4.8 / 5 from 876 reviews.
Muy buen modelo, las instrucciones son claras. Muy contento
Not for the weak-armed. This is a massive build; the hull is over 50 cm long. The instructions are easy to follow, though it is occasionally unclear exactly where pieces should go, as the images don't always show the best angle. The clutch power of the bricks is a bit inconsistent, though generally excellent. One area for improvement, however, is that the instructions for when and where to apply the stickers are located on the very last page of the booklet. This makes accessing certain sections very difficult. Some parts are also extremely fragile—falling off if you so much as look at them the wrong way—so trying to apply stickers often results in everything coming apart at least five times. The final result, however, is truly impressive.
Smaller than a car set but just as detailed, would recommend
Different from the usual cars and it's awesome
Kupiłem synowi, jest zachwycony
Paint/colour looks great under the light, took a pic for you guys
Looks great but some of the stickers were hard to line up. Still happy
Good quality, took longer than I expected. Four stars because shipping was slow
Finished last night. Fit is tight so go easy on the long axles but nothing broke
