Hollow Yves (pronounced "Hollow Eve") is the skull-bow around Alice Liddell's waist. His appearance differs depending on Alice's Wonderland and Otherland dresses. Although Alice's bows are all different shapes and sizes, they are all undoubtedly Hollow Yves. In Madness Returns, Hollow Yves appears during weapon upgrades. It is implied that he is sentient and has the ability to speak to Alice, but his voice is unheard.
