The head piece comes in the form of an almost solid, round, hard, black enclosure, used to completely remove any of Alexandra’s remaining identifiable features, making her absolutely unrecognizable and anonymous. Solid, with no way to see through it or any other encasement layer that later on covers her, it makes Alexandra fully anonymous and gives her the signature Bane look. The sensors in Alexandra’s artificial eyes aren’t hindered in any way by the encasement over it, still allowing for perfect optical signals and all other signals to pass through the helmet and remaining encasement layers.
The facial section of the helmet functions similarly to the area of the corset armour over Alexandra’s nipples or the genial area. Usually, just a smooth oval shape, it can be controlled and changed by Lumina to mimic facial expressions and movement. This is later on used by Lumina and the many different shells to mimic facial movement and expressions, by manipulating that area. Except for those scenarios, the helmet always has the solid, smooth oval area, leaving no trace of any facial feature on Alexandra.
It also features an attached neck-section, working similarly to the corset armour, which allows for Alexandra’s neck position and head posture to be fully controlled. Once the head shell is in place, any remaining space within it is pumped full of the same solution as the first encasement layer, fully binding it to Alexandra’s new skin layer. Finally, the entire head piece is also covered with the same black latex solution as the rest of the second encasement layer.
