Origin
Midtown High student Jessica Campbell was present when Peter Parker was bitten by the irradiated spider, which gave him his powers. She had a crush on him, and had just plucked up the courage to speak to him when he was distracted by the bite. She also had a celebrity crush on teen heart-throb Johnny Storm.
Jessica's father received tickets for Disneyland from his boss Tony Stark. On the way home, their car collided with a military convoy carrying radioactive chemicals. Her family was killed, and, after spending several months in a coma, she awoke, stirred by the first coming of Galactus outside her hospital room. She was placed in an orphanage and adopted by the Jones family.
Jessica later discovered that her radiation exposure granted her super strength, limited invulnerability, and flight (which she never fully mastered during her superhero career). The Joneses re-enrolled Jessica at Midtown High, where she was ostracized by her classmates, especially Flash Thompson. Peter Parker (who had since become Spider-Man) sensed in Jessica a kindred spirit—someone who had also lost family due to a tragic circumstance. Jessica mistook his kind attention and lashed out at him, believing he was merely pitying her.
She later witnessed a fight between Spider-Man and the villain Sandman in her own class. This inspired her, in a way she couldn't put into words, to use her abilities in a positive light.
Heroic career
As Jewel, Jones was an upstart heroine with a fairly uneventful career until she intervened in a disturbance at a restaurant involving longtime Daredevil foe Zebediah Killgrave, the Purple Man. Killgrave used his power of mind control to place Jones under his command, psychologically torturing her and forcing her to aid his criminal schemes. After eight months, Jones began to lose the distinction between his will and her own, developing a kind of Stockholm Syndrome.
In the midst of a temper tantrum, the Purple Man sent Jones to kill Daredevil, erroneously directing her to the Avengers Mansion. Jones attacked the first hero she saw there in a red costume, the Scarlet Witch. The mind control began to wear off and Jones attempted to flee, but she was caught and severely injured by the Vision (the Scarlet Witch's then-husband), and Iron Man. She escaped due to the intervention of the only Avenger who actually knew her, Carol Danvers, who took her to safety.
Jones remained in a coma for months, under the care of S.H.I.E.L.D., while also undergoing psychic therapy with Jean Grey of the X-Men. In addition to assisting her emergence from the coma, Grey placed a special mental command in Jones's subconscious that would protect her from further mind control.[9] During this time, Jones developed a doomed romantic relationship with S.H.I.E.L.D. agent Clay Quartermain, who would prove to be a valuable friend and contact for her later in life.
The intensely violating nature of her experience with Killgrave, combined with the fact that no one noticed she had been missing for eight months, forced a demoralized Jones to give up being a costumed superhero.
In the final issue of The Pulse, Jones tried being a superhero one final time before giving up, adopting a darker identity as the Knightress. Intercepting a crime meeting between the Owl and a mafioso, she met up with fellow superhero Luke Cage. After defeating the Owl and his goons, she discovered that one of the thugs had brought his children with him. Jones took off her mask and revealed her identity to the cops so that they would allow her to look after the children for the night. Luke Cage went to her home later that night and the two had a long talk, the first step toward a lasting friendship.
