First off- the most common question I get before anyone asks is where I got the mask. I had it custom made by another Bionicle fan from DeviantART about two years ago that no longer makes custom masks.
Toa Crypto is my self MOC. I haven't really decided on a power for her yet. I was thinking about going with Void-like powers but still need to consider it more before making it "official".
The left arm is a custom one and is suppose to be fully robotic as my self-MOC lost it in a battle that left her nearly dead and the loss of her arm.
Toa Crypto while not shown on this picture, carries a sniper rifle on her back along with a two hand sword, claws rest on her waist ready to use, the black objects you see on the leg armor can be detached and are actually pistols, she also can have a hidden blade attached underneath her robotic arm. She carries a full arsenal of weapons and is considered more of an "assassin" like Toa than anything given how many weapons she can carry and how agile she is.
I also have a MOC video of her here you guys can check out if you want to see more pictures (I deleted all but this one sorry )
