Jessica Jones

Origin

Jessica Campbell was just about to to speak to her crush, Peter Parker, before being distracted by the spider bite that gave him his powers. While going home, she and her parents are in their family car when it collided to a military truck that is carrying radioactive chemical. Her parents were killed and Jessica slipped into a coma. She was then adopted by the Jones family and she woke up from her coma during the time of the coming of Galactus to earth to feast on the planet. She was enrolled back to Midtown High School, where she was at the receiving end of bullying by Flash Thompson. 

Luke Cage

Peter felt empathy towards Jessica as he grew up without his true parents, but Jessica lashed out to him because she thought that he was pitying her. It was at this time that the exposure from the radioactive chemicals gave her powers. As the superhero Jewel she had a brief career thwarting crime. During one of her adventures, she ran into the mind controlling Purple Man. He took control of her life and used her in many unpleasant ways. He eventually tried to use her to kill Daredevil, but instead she attacked the first person she saw in a red costume, which happened to be the Scarlet Witch. After a fight with the Avengers they helped to free her of the mind control, and even offered her a place on the roster. She declined, quite disturbed by the abuse the Purple Man inflicted upon her.

She started the Alias private detective agency and worked for some interesting clients, including Matt Murdock. During this time she became pregnant by Luke Cage and briefly dated Scott Lang.

Scott Lang

Later, she was offered a job working for the Daily Bugle on the superhero column The Pulse. She ended up arguing with J. Jonah Jameson over his opinions of costumed heroes and quit before the birth of her child. She and Luke Cage have since married.

Civil War

She is on the run from the law with her husband Luke Cage and their baby daughter Danielle. The new family is in hiding with the New Avengers.

It has been speculated that Jessica might be a Skrull because her baby lit her eyes with a green flash. After the New Avengers fought and defeated The Hood's Gang, she feared for her safety and her baby and so she goes to see Iron Man to register.

Secret Invasion

Baby Girl

When a Skrull ship crash landed in the Savage Land, the Avengers goes out to investigate. What is inside of the ship was some of pre-existing heroes, including Jessica in her Jewel costume. When she was later revealed to be a Skrull, she was killed along with the heroes from the Skrull ship. The real Jessica Jones was present in the final battle between earth's heroes and villains fighting together against the invading Skrull empire. After the Skrulls lost, the Skrull that masqueraded as Jarvis kidnapped her child and disappeared.

Powers and Abilities

Jessica has superhuman strength (able to lift at least 2 tons) and durability.  She is also capable of flight although she does not have full control of it. Because of the manipulations of Purple Man, Jean Grey has put psychic barriers in Jessica's mind to provide some protection from mental attacks. She is also a skilled detective and journalist.
