I remember that the Masks are not allowed to hold more than one element. My question is are we for example with tahu getting a mask of fire or a Hau?
Mask powers as elements are confirmed
Although I'd like to think that the golden masks would contain abilities relating to their old powers... like, when Tahu gets his gold mask, he gets the power of the "Fire Shield" or something like that...
That would've been really cool, although I'm fine with elements.
Where was it Confirmed?
In the BIONICLE 2015 Legend minimovie from NYCC.
It was also confirmed in the Master's Bios.
What ekorak and nuparu said
I'm just not okay with lewa cuz I still don't know what kind of powers does he have. If it's air powers listed on BIONICLE page or jungle powers which are in his title and they are listed on official web too.
Elemental masks sound cool. I was hoping for the old mask powers though but its ok.
