Lurker is said to be a dark hunter, who after joining picked upgrades including 2 kanohi, which he put on shoulders to look like a winner. However both of them bear an appearance of Hau Nuva/Aki Nuva. Both of which didn't even exist at that time, so my question is: What are those masks?
I see several options:
1) These masks are Masks of Charisma in different form than we see on Trinuma.
2) These are other masks we see (or not) in canon, that as Mask of Charisma coincidentally bear an appearance of some form of Hau Nuva, but then which ones?
3) These are compeletely different masks only resmbling this shape, but then what mask do they resemble?
4) Lurker's appearance simply isn't canon.
