Annie The Assassin

Annie The Assassin is a world-renowned assassin and a member of the The Gang Of Five alongside her husband Robert The Rat, and close friends Michael Mouse, Jean the Genocidal Genet and the current fifth member of the Gang of Five. She has been on Unsociable Planet's 100 Most Dangerous Things List since its inception. She is almost certainly the best assassin in the world currently, and a strong candidate for the best assassin ever, with perhaps her most high-profile target being Kruschinov.

Before the Gang of Five
Little is known of Annie's life before joining the gang. It has been claimed by some that she grew up a street orphan, learning to fend for herself; and by others that she was brought up in a strict household, trained from infancy to be a killer; before at some stage before the age of 10 she wound up in Mrs. Pereditory's Home For Criminally Insane Children, where she stayed until the age of 21, being a top student and winning the Pereditory Star For The Most Evil Student in her 5th, 6th and 11th years at the school. She graduated with a Ph.D. in Assassination and Masters Degrees in Homicide, Poisoning and a Bachelor of Arts in Concealment and Infiltration.

Gang Of Five
Approximately eighteen months after graduating, Annie joined with four of her classmates, Michael, Jean, Robert and Peter the Pyromaniac to form the Gang of Five. The gang perpetuated numerous atrocities and heinous crimes throughout the next decades, including Annie's assassination of Kruschinov. During this period, Annie married Robert The Rat.

This ended with Operation Twelvetree, which killed Peter and lead to the dissolution of the gang. After this Annie lived with Robert in a (relatively) quiet life, until the gang was reformed. Since then the Gang of Five has returned to being one of the deadliest groups in the world.
