To provide Alexandra with substantially more strength and control once she’s fully transformed into a Bane, a network of artificial muscle fibres is placed over a large majority of her body, over the armour layer. These artificial fibres are fully controlled by Lumina, but when under Alexandra’s control, allow her to achieve far greater strength than a normal human could.
Only activated when really needed, this layer of extremely dense and compressed artificial muscle fibres would allow Alexandra to lift a small car, while still only standing on her needle like en-pointe feet.
The muscle fibres are connected to the armour layer underneath it and after application, this layer is again covered by the same black latex solution.
These artificial muscles eventually become so natural to Alexandra, that they’ve just become of her muscular system, her mind making no difference between the two.
