The Miserix Revamp has no reason to be canon, no matter if it’s the original creator or not. It’s still a revamp - not the model that was canonized. Same as if MisterN was to redraw Helryx now, that redrawing would not be canon, and rather irrelevant to mention on BS01. The BS01 article is not for following the creator’s career.
No, the post was mistaken.
Actually, according to this post the story came from the creator, not from Greg. With the entries, the MOCists had to send in an essay on their creation. This is why we can fully blame Krakua for the Mask of Telepathy and the element of Sonics, they were chosen by the creator.
