Rayna Boyanov is the secondary antagonist of Spy.
She is portrayed by Rose Byrne.
Rayna is an arms dealer as well as murderer who is responsible for deaths of the spies whom she knows their identities, including Susan's crush and former partner Bradley Fine. It drove Susan Copper to go on her first undercover assignment to get revenge on Rayna and prevent the Global disaster and Fine's death (the latter turned out to be a ruse). She shares many traits as a psychopath. Showing little to no emotions, having no empathy for anybody or anything, and willing to murder on a whim without thought and/or emotion.
Susan ends up Rayna's life three times, and although at the end of the film Susan has to take her into custody, the two have become genuine friends.
