Most Accurate Build
SerialBuilder's Thunderjaw is so close to the in-game machine that you'd be mistaken for thinking it was an actual scale model. Highly detailed and posable for an iconic display that'll be sure to stand out as part of your collection.
Weapon Systems
The iconic disc launcher and head canons are accurately designed making the Thunderjaw unmistakeable at a glance.

Mechanical Realism
Advanced building techniques create the appearance of complex mechanical systems beneath the armour, giving the model depth and complexity that really make it come to life.
Articulating Jaw
The Thunderjaw is highly posable with many points of articulation allowing for the desired look

Our thoughts on the design
The Thunderjaw is one of SerialBuilder's most iconic builds since it looks so accurate and commands an imposing presence in any display. All the elements of the beast including its weapons systems and radar are there as well as the gattling guns along the neck. It's a fun build and certainly the best version that's out there. We wish it was more self-standing or had an integrated base like the other big beasts to prop it up instead of the stand, but for a design like the Thunderjaw, the physics are a little hazy. As for the build, some panels can be a bit tighter or have a few extra studs for connection, but overall a really solid build that just looks as menacing as the one in-game.

Fixes we've made
Redesigned the neck panels for improved stability
For the original design, the neck panels were using single-stud attachments in some places which made them fairly fragile and would fall off from accidental knocks. We redesigned them completely to be sturdier whilst still keeping true to the original design as much as possible.
Severity: Medium
Added extra stability to the jaw elements
We improved the connection of the jaw elements as it original had a single stud attachment and would fall off it held from that part.
Severity: Low
Improved leg panels
Some leg panels featured too few attachment points which meant that they would more easily fall off if moving the model. We made a small update to make them a little sturdier and able to attach with more clutch power to the skeleton.
Severity: Low
Removed the stand
This is not quite a fix, since we don't recommend the model to be displayed in this way, but we updated the design to allow for the stand to be removed after the build has been completed.

A brilliant experience and a feast for the eyes
Another really fun set to build! It’s amazing just how detailed the set is.
Most Surprising Thing
You can adjust the position yourself. This makes the set less static and better suited to the space where I want to put it.
What Can We Do Better?
Perhaps an attractive base plate and slightly more visible ‘eyes’.
Massive and impressive build, with some small issues
Overall this is a great build and looks amazing when finished, although I did have a few small problems. Some steps are quite hard to do properly (Attaching the gear mechanism for the legs, for instance) and quite a few are a bit unclear (like attaching the armor plates to the neck). The only real problem I faced was getting the ammo belts(?) to the head assembled, as the flexible hose piece seem just slightly too thick. Despite those small problems, I'd absolutely still recommend this build, especially when considering the price.
Most Surprising Thing
How much technic there is to support the model, which makes it very sturdy. The amount of posability was also suprising
What Can We Do Better?
clarify instructions when mounting the armour pieces (Maybe highlighting the exact hole that should be used?), and slightly easier to assemble ammo be...
What comes after lightning? THUNDERJAW!!
Had a wonderful time building this bad boy and putting him on the shelf with the others. Absolutely love the size of him.
FIRST build complete
Took a while but after 3 months with long breaks I manager to build the Thunderjaw with my 6yr old son. Great experience and family time. Build is great overall, some parts imo should get a better support (Fall off to easily during adjustments, ie: neck armor but its great for fun when playing lego horizon stories with my Son so I do not consider this a big issue :). The hardest step was 1072/1075 as the parts do not slide in easily, also the small gears in step 1059/1069 tend to stick out a bit and block the rotation of the turrets) Some parts are different color than in instruction but its just cosmetics. Can't wait for next builds!
Most Surprising Thing
Its complex but easy to build. 80% of the build was done solo by my 6yr old.
What Can We Do Better?
Printed instructions would be great (maybe as an option) Additional internal box packaging for different builds would add a better premium feel instea...
