What is a LEGO® MOC?

Some of you may be wondering what a LEGO® MOC is. What does MOC mean?

MOC is an acronym for My Own Creation. LEGO® MOC, therefore, means LEGO My Own Creation, and are creations that have been designed and built by LEGO fans, using original LEGO® bricks. These creations or MOCs as we call them, serve as proof that with imagination and a few LEGO® bricks, you can build anything!

As good as most original LEGO® sets are, people will always come up with amazing alternative designs for what they love. LEGO ®encourages and inspires people to use the parts in completely new and different ways. You can use the parts from a LEGO® house set, to build something like the bee here!

These designers also create the custom LEGO® instructions to build their custom kits. These sets come with all LEGO® parts and instructions necessary to be built.

Just like LEGO's own product lines, there are many different MOC categories. We explain some of them in this page.

Popular LEGO® MOC Categories

Technic MOCs

These MOCs are built using LEGO® Technic elements. LEGO® Technic is a line which uses different components to be able to create more complex and functional structures. With rods, axles, gears and mechanical components, you are able to create complex structures such as functioning gearboxes!

Architecture MOCs

The LEGO® architecture theme has a very distinct micro-scale style. The MOCs that fall within this category try to achieve the same style with different builds, such as this Harry Potter universe inspired MOC.

Automaton MOCs

LEGO® Automaton MOCs are one of the most interesting kind of MOCs. They usually mix regular and Technic LEGO® elements, to recreate a "living scene" of some sorts.

The creator TonyFlow76 is a great Automaton MOC designer, and you can view most of his designs on Youtube.
