The is no Mask of Nothing...
Bionicle Mask of Light.
Bionicle: The mask of light.
Bionicle set No. 6620, also known as the "Matoro" set, includes various pieces that allow for the construction of the character Matoro from the Bionicle universe. The set typically features a combination of Technic elements, including a body frame, limbs, and a mask representing Matoro's Kanohi mask. Additionally, it may include various connectors and armor pieces that enhance the character's design and functionality.
I think so.
There is no website where you can make your own Bionicle mask.
Gelu doesn't have a mask. He wears a helmet.
There is no BIONICLE movie in 2001. You probably mean the movie from 2003 (BIONICLE: Mask of Light)
A Kanohi is the name of a mask in Bionicle. In the Bionicle story, the Matoran name of a mask is 'kanohi'. Each Kanohi has another name (eg.: Toa Tahu's mask: The Kanohi Hau).
BIONICLE: Mask of light, BIONICLE 2 : Legends of metru nui, BIONICLE 3 : Web of shadows, and the newest one BIONICLE 4 : the legend reborn.
I think you mean Nektann, but he is a skakdi, and he doesn't wear a mask!
If you have Bio-codes (you will find Bio-codes on the back of Bionicle sets), you can put these codes on the Bionicle website. If you have a few of these codes, you get your kanohi mask badge.
