Harry Potter Character of the Issue - Bellatrix Lestrange

Born in 1951 Bellatrix Lestrange was born to her parents Cygnus Black III and Druella Black. Her parents raised her to be proud of her pure blood ancestry.  She was the oldest daughter of the black clan and also sister to Andromeda and Narcissa Black. However, she broke off speaking terms with Andromeda after she married a muggle.

Bellatrix Lestrange was given the best that money can buy. She was put into the Slytherin house at Hogwarts School of Witchcraft and Wizardry. Afterwards, she soon married Rodolphus Lestrange, who was also a wealthy pure blood Slytherin. Bellatrix showed no sign of affection for her husband unlike her sisters.

Bellatrix and her husband soon joined a few members in a group and became Death Eaters for the Dark Lord. She always showered him with affection unlike her husband but she always believed He-Who-Must-Not-Be-Named was her one true love but he would never be able to return the favor.

She remained loyal to him through the wars and was loyal even when Harry Potter defeated him. She and a few other members that were loyal to He-Who-Must-Not-Be-Named together kidnapped Alice and Frank Longbottom who just had a son together. They tortured them to gather information on He-Who-Must-Not-Be-Named's location. But they never gave the information and the memory left them leaving them to spend their days in a hospital unknowing of their son. 

Between the wars, Bellatrix was sentenced to life in Azkaban with no chance of release. In 1995 when He-Who-Must-Not-Be-Named returned to power she broke free from Azkaban with ten other inner circle Death Eaters.

Later that year she was involved in yet another war where He-Who-Must-Not-Be-Named worked hard to defeat the department of mysteries. She had found Neville Longbottom and tortured him just like she did to his parents. Bellatrix saw her niece and battled and defeated her and then moved on to Sirius, defeating and killing him.

In 1996 she oversaw the making of the Unbreakable vow between her sister Narcissa Malfoy and fellow Death Eater Severus Snape, in an attempt to protect Narcissa's son Draco from harm.
