Sailor Doom

Possible plot where she fights Ben when she sees a sailor moon villain and immodestly tries to kill them. A bad end if Doom wins, a good end if they throw the fight. (Cus beating up your partner is bad)

Sailor Doom has nightmares of the hell dimension she came from nearly every night when she first arrives and relies on Ben to calm her nerves when she awakes. Should Ben have to leave early and not be there when she wakes it may sound like this: Limp Bizkit - Break Stuff
Possibly during one of these tares she encounters Minako Aino/Sailor Venus in her Sailor V persona.
