>>46532970Seems to be an addition Sugimori made in the new FRLG artwork. Old art/anime screencaps show no side appendages. The closest I can find is some promotional anime artwork that KIND OF resembles the side spikes, but is more likely just the dress folds in a manner of perspective.
I wonder if the Jynx controversy (MUH BLACK WOOMAN) made them want to add features that were more unhuman-like.
