This is Slayer! A dark hunter whose arm was sliced off by one of the Toa Mangai during the Toa-Dark Hunter war. He got a new arm imbued with ice powers and vowed to never be defeated by a Toa again, especially a Toa of ice. I’m not sure if it fits 2004 Bionicle aesthetic but I’m pleased with how this MOC turned out. The zamor spheres should be orange and the flame thrower thing should be his main weapon but it is very heavy for his arm. Also, those gun-metal pieces by his eyes should probably be black.
On Instagram, I’m captain_subtle as well by the way.
Thanks! Yeah, the build is a bit unpolished. If I ever build him again then I’ll probably change the legs a bit along with some gappy or weirdly textured sections here and there. For the head, I was pleased to discover that way of using Jetrax Antroz’s mask.
