Here's my self-MOC:
This is actually my third (some might say fourth) MOC using the same torso and arms. First it was a Hero with a bunch of weapons (known as Ultimate Hero). Ultimate Hero went through several revamps. Then when Bionicle 2015 came out, I changed him to a Toa named Unnamed Toa (because I have a hard time coming up with names). Then I made him The Monster (on the boards for those who want to check it out) for a few Halloween MOC competitions. Now I changed it to this, which is basically Unnamed with a Volitak.
