In the film Hanna's year and place of birth are not revealed but in the TV series she is shown in 2003 as a very small baby in a secret facility in Darabani, Romania. In both the film and the series she is 15 years old except in brief flashbacks to her earlier life. Her birth mother was Johanna who died whilst she was rescuing Hanna from the facility with her partner, German former CIA agent Erik Heller. Erik escapes with Hanna and her childhood and early adolescence is spent living alone with him in the forest to hide from the CIA. For the first 15 years of her life Hanna believes Erik to be her birth father, but she later learns he is not. It is revealed that Erik persuaded Johanna not to abort Hanna so the baby could be part of a CIA programme called UTRAX. In the television series it is revealed that Hanna's real father is named Emil Prodna and at the time Emil did not want to have a relationship with Johanna and have Hanna as his daughter. However when Erik takes her at the age of 15 to meet Emil, his current wife, and his other three children, Emil is happy to meet Hanna and offers her a place to stay in safety. Hanna however gives this up for Erik.
Appearance and character
Hanna is 5ft 2in tall with blue eyes. In the film she has blonde hair, but in the TV series it is brown, although in season 2, she dyes her hair blonde. She has pale skin and her build is slim and athletic, partly due to the intense physical exercise that Erik makes her undertake and partly due to the fact that the CIA used UTRAX to enhanced her DNA in order to breed super soldiers. Due to this Hanna is exceptionally strong for a girl her age and build and has great stamina when running. As she lived in the forest she was home schooled by Erik. Whilst not being unlearned at all she has little knowledge of the practicalities of the modern outside world. Erik raised her to be prolific in languages as she speaks at least English, German, Italian and French. Aside from that she excels at hunting and shooting and hand-to-hand combat skills Erik knew she'd need when she left the forest to evade the CIA. Hanna's first friendship is with a 17 year old Polish logger in the forest and her first close friend is an English girl named Sophie who is around her own age. Having been raised alone by her Erik she has nothing but theoretical knowledge of romance. She rejects the advances of boys who like her, except when she drinks some vodka. Not knowing the effect the drink would have on her she kisses a boy in what others see as an unacceptable public display of affection, whilst she knows no better. She later loses her virginity to an English boy called Anton. It is hinted that Sophie is sexually attracted to Hanna and at one stage Sophie kisses her on the mouth, but Hanna just sees this as a normal part of friendship. Her character is summarised on one of the promotional film posters as "Young. Sweet. Innocent. Deadly." When Marissa Wiegler, Hanna and Erik's nemesis, tries to befriend the girl by labelling her "unique" Hanna replies "Unique just means alone". Sophie's mother Rachel comments that Hanna is much like her at her age a "loner".
