I’m a huge fan of the Iron Man Hulkbuster armor and when I started to collect Iron Man minifigures I’ve decided to create one to add to the armory.

My first attempt to create a Hulkbuster armor that can be piloted by an Iron Man minifigure is when I got my hands on a Kai’s Fire Mech set from the LEGO Ninjago line. My first attempt consists of just modifying the hands and ditched the gun right hand design. I was already happy with what I came up with but I was not satisfied with my final design.

After looking at the other Hulkbuster builds from other LEGO enthusiasts I’ve decided to rebuild the armor, this time using an additional Fire Mech set and parts from the Iron Man Ultrabuild set.

My challenge now is to create a sleek Hulkbuster Iron Man build using only parts from these 3 sets (2 x Fire Mech, 1 x Iron Man Ultrabuild).

Thanks to the additional parts from the Fire Mech the minifigure is now fully enclosed except for the head. I'm also quite happy that I was able to add more design elements thanks to the Ultrabuild's chest armor and the curved blocks and vents from the mech sets.
