Blade's companion, who goes by the name Needless, possesses a unique ability known as Doppelganger. This power allows her to transform into other individuals or simply alter specific parts of her body into different objects (such as turning her arm into a drill). Despite her good intentions, she can be impulsive and dim-witted, giving the impression that she is immature. Her ability consumes a significant amount of energy, causing her to frequently drink Super Dero Doro soda, which contains an astonishing 5000 calories per can. Additionally, Needless has a penchant for nicknaming individuals (like addressing Cruz Yamada as "Cruz-san").
