We’ve seen Great masks turn into Noble masks when Toa turn into Turaga, but can the opposite occur when Matoran with Noble masks turn into Toa?
I hope the answer is yes, as this happens in a fanfic I’m writing
Greg has answered this on another platform, where he answered yes, if it is worn by a Matoran who is transformed into a Toa, it transforms into a Great mask. It remains a Noble mask if someone who already is a Toa puts it on, as seen with the Toa Mata in 2001.
