The masks resemble the bone-like coverings on the faces of the Grimm. Several different masks are seen throughout the series. However, they all share an overall gray or white coloration and the intimidating appearance that conceals the identity of the wearer. According to Blake Belladonna, the White Fang's use of the Grimm masks are a response to humanity seeking to make Faunus into monsters.
- Recruits - These Grimm masks are worn by new recruits of the White Fang, as seen at the White Fang Faction Meeting in "Painting the Town...". They feature two pairs of eyeslits and sport an angular shape, pointing downwards, covering the nose and a portion of the cheekbone.
- Soldiers - Worn by White Fang's soldiers, this variant of Grimm mask is more rounded, covering the wearer's cheeks and featuring a pair of fang-like points around the mouth area.
- Officers - Higher ranking White Fang members, like Adam Taurus and the White Fang Lieutenant, seem to possess custom masks. These masks differ from their counterparts owned by the underlings for their red markings, whiter color, and can even possess completely unique designs.
- Adam Taurus - Adam's Grimm mask resembles the recruit mask. However, it is distinguished by its whiter color and intricate red markings.
- White Fang Lieutenant - The Lieutenant's Grimm mask has a unique design, similar in color to Adam's and likewise detailed with red markings, but covering his entire face and possessing only one pair of eyeslits.
- Ilia Amitola - Ilia's mask sports a more triangular and reptilian design. It has two pairs of eye slits, two small horns, and possesses the coloration and red markings similar to that of the other officers. The mask is destroyed when Ilia headbutts Sun Wukong as he tried to subdue her.
- Raven Branwen - Raven's Grimm mask has a fearsome design and shares some similar design elements to its counterparts in the White Fang, including the red markings. Her mask covers her entire face and has two pairs of eyeslits through which her eyes are visible. Its overall shape is more rounded and tapers to a sharp point, somewhat resembling a bird's skull.
