Kybran

The Kanohi Kybran is the Mask of Density Control.

It functions identically to the Kraata power of the same name in that the bearer can use it to increase or decrease their own density to make oneself heavier or lighter, so that they gain increased resistance to physical blows or become able to leap great heights. It differs from the Mask of Gravity in this respect, as wearers of the Garai cannot use its powers on his or herself.

The only known wearer of this mask is Makuta Ferox, who has outfitted his with a breathing apparatus to protect him while conducting experiments involving gaseous substances.
