Crew Patty (パティ·クルー, Patty Crew) is a member of P.A.N.D.R.A.
Patty has a large interest in yaoi pairings, due to Hyoubu just copying how Bullet and Tim were treated during their recovery with somewhat little regard, and her normal taciturn personality will change upon seeing any of the male members of P.A.N.D.R.A. (or even male members of B.A.B.E.L.) in questionable situations. This extends to the omake pages where Patty apparently draws doujinshi with male pairings for a hobby, and visits comic conventions and otaku-related places such as Akihabara.
Patty Crew was originally part of Black Phantom. In a mission with Kaoru, Momiji, Kazura, Kagari, Mio and Momotarō, Patty was the target to be saved from the organization. She was being used to destroy P.A.N.D.R.A. Although Kaoru destroyed the grip on her by Black Phantom, she tried to kill herself because of the mind-control self-destruct program inside her head which activates after a loss. Hyoubu speculates that the Pandra Boost was not a complete success because of this fact; this is likely considering Kaoru realized the power was weaker. In the end of the anime and also in recent manga chapters, Patty has been shown to have joined P.A.N.D.R.A.
Patty Crew is a powerful esper capable of synthesizing a variety of psychic abilities to transform her body into a form of mist.
