Description
How the build works
Bionicle sets do not work like a typical plate-and-brick model. Hydraxon is assembled around ball joints, axles and connectors, with curved armour pieces clipped onto a poseable frame. At 165 pieces it sits in the mid-range for a single hero figure. You build the limbs and torso as separate units and join them at the end, which means every section can be tested and posed before the figure is finished. It also makes the build feel varied, because you are not stacking layers upwards but growing a skeleton limb by limb.
A dark palette with a touch of blue
The main colours are black, pearl light grey, light bluish grey and blue. Together they give the figure a dark, metallic look, with the blue picking out details against the grey. Pearl light grey has a slight sheen and turned up often in Bionicle sets of this period. If you want to reuse the colours in your own creations, the parts list shows exactly which elements come in which shade. That is especially useful with the greys, which are hard to tell apart at a glance and easy to mix up when sorting.
Many different parts for a small set
Of the 165 pieces, 54 are different parts, which is a high ratio for a set this size. It reflects how specialised Bionicle elements are: claws, joint covers and weapon pieces appear almost exclusively in this range. That makes the parts list handy if you are missing something, because you can look up single elements and see which ones you need to replace without buying the whole set again.
Posing, display and rebuilding
A figure like this works for play, for the shelf and for rebuilding. Joints and axles are compatible with other Bionicle sets of the era, so arms, legs and weapons can be mixed between figures. If you already own a few, the “What can I build?” feature on this page shows which extra models your collected parts allow, and the parts list helps with sorting out what belongs where.
