Similar to @Darknova3529’s Artakha, I like the idea of Artakha literally being himself a forge. It harkens back to the early years of Bionicle when everything had a clear part to play in the Great Spirit Robot. In that context, a walking, talking forge actually seems a lot more plausible.
That said, this seems a bit too far outside the realm of plausibility for what Artakha could canonically look like. I still love this as a standalone MOC, but I’m probably not going to be voting for it in this contest.
