Origin

Teresa Parker is the daughter of CIA agents, Richard and Mary Parker. She is also the long-lost sister of Peter Parker, aka Spider-Man. Despite being active field agents, Richad and Mary desperately wanted to start a family. They had Peter, who spent much of his time in Queens with his aunt and uncle, while his parents were away on missions. During these missions, Mary got pregnant. She kept it a secret from the CIA, going as far to pitch an undercover mission where she would fake being pregnant to infiltrate a biolab posing as a hospital. The data they recovered would be responsible for SHIELD's life model decoy program. Unfortunately, Richard and Mary died on a mission before she could introduce Teresa to her brother, uncle, and aunt. She grew up never knowing her family and educated by a school that trained orphans for a future in spycraft.

Teresa Parker was created by Mark Waid, James Robinson, and Gabriele Dell'Otto and first appeared in the Amazing Spider-Man: Family Business - Original Graphic Novel (2014).

Family Business

Between missions, Teresa used her CIA resources to locate her parents, but her birth records were buried well. It wasn’t until an investigation into an international criminal conspiracy turned up a connection to “the son of Richard Parker.” Her background check on Peter finally turned up her birth records, finally revealing her name, parents, and the brother she never knew she had. She traveled to New York City just in time to save Peter from a team of enforcers and brought him to Europe to help her investigation, even though he was skeptical of her claims of kinship.

They tracked down Emile Chigaru, a former handler for Richard and Mary, to ask why Peter was so important. Emile told a story of the Parkers taking down a Hydra sect guarding a cache a Nazi gold with a Sleeper robot in Cairo. After defeating the sect, the Parkers disarmed the Sleeper with a series of biometrics that Peter, as the spitting image of his dad, could unlock. They decide to get to the robot before anyone else can, but they are attacked on their way. Peter ends up revealing himself as Spider-Man to her.

With a new black suit made by the CIA, Teresa and Peter break into a Cairo tomb only to find Kingpin and his task force Fisk had been using a psychic mutant, Mentallo, to manipulate Teresa’s memories and mask him from Spidey’s spider-sense so that he can get to the Nazi gold. With Teresa’s life on the line, Spidey unlocks the Sleeper and then takes it on by himself. Teresa stays behind and gets into a firefight with Fisk and his men. Mentallo, who gets sick of being abused by Fisk, uses his powers to wipe Fisk and Teresa’s memories of Peter and his identity as Spider-Man.

Most Wanted

After her adventure with Spider-Man, Teresa quit the CIA and got a job with a SHIELD offshoot called The Gray Blade. She felt like it was noble work until she discovered Project Twilight, an exhaustive plan to take down all superhumans, heroes and villains alike. She wiped the memory but first created a copy of the data as nanofluids that she injected into her own bloodstream. She tried to take the files to SHIELD proper, but the Gray Blade already put a shoot to kill order on her. She went to Peter Parker, who she eventually remembered, proving Mentallo’s brain blast was only temporary. She never divulged their relationship to her employers. Despite not actually being siblings, she trusts him and needed a place to stay.

At the same time, Peter was investigating untraceable phones flooding New York’s criminal networks, thanks to Kingpin. He and Human Torch were going to confront Fisk, and Teresa refused to stay behind. To keep her safe, Spidey had her outfitted with a super suit with folding wings and a pair of high-tech pistols thanks to Hophni Mason. Their lead on Kingpin was a dead-end, and Fisk implied his reveal that Teresa and Peter weren’t really related was a double bluff. Unfortunately, while they were staking out Kingpin on the roof, someone caught a picture of them. It was submitted to the media describing Teresa as a fugitive working with Spider-Man.

They now needed to find a better place for Teresa to lay low. With the FBI and multiple superhumans on their tail, Spidey left Teresa with Hophni, who promised to get her a blood transfusion to secure the nanofluid data. Unfortunately, Hophni revealed himself to be The Tinkerer, who had gathered the anti-superhuman data by working on their upgrades. Spidey and the superhumans teamed up to take out Tinkerer and his goons, revealing his connection to The Grey Blade.

Amazing Fantasy

Tinkerer proved to be responsible for the untraceable phones. He was using them to mimic an A.I. population and get the attention of the A,I. alien race, The Vedomi. Project: Twilight was to disarm the superhumans against the robots thinking he would be accepted by them. Tinkerer found a way to disarm them, but the records were destroyed in a warehouse fire years ago. Spidey would come up with a plan using Dr. Doom’s time platform to go back in time and get the records. Teresa and Jameson would join him.

While Spidey and Jameson worked with their younger selves, Teresa got a meeting with her former boss, Nick Fury, during a time when they hadn’t met yet. She couldn’t help but ask about Richad and Mary Parker. Fury showed her a CIA safe house the Parkers used. Fury mentioned a mission where Mary went undercover as a pregnant woman, and Teresa found a picture of Mary holding her.

Unfortunately, their time in this alternate timeline has been effecting change. For one, Tinkerer committed one of his crimes early. Jonah and Teresa were forced to track him alone to a warehouse district. Spidey was busy with Green Goblin who learned of Peter’s identity and kidnapped this timeline’s May and Peter. When Tinkerer defended himself, he started the warehouse fire, but Teresa secured the records despite this.

Ready to go home, Teresa first proved to Peter that they were really siblings. After a brief stint in the wrong present, they finally made it back to their time and reality, where they use the secret weapon to defeat the Vedomi.

Chameleon Conspiracy

When Teresa got a distress signal on an old SHIELD line from her ex-boyfriend spy, David Albricht, she enlisted Spider-Man’s help to track him down. Unfortunately, they found him dead in an old AIM lab being used by The Chameleon. Chameleon had tortured David to death, extracting the location of SHIELD assets from his head. They managed to track him down after he planned an assassination attempt on Doctor Doom on behalf of a deposed leader of Symkaria. After he was arrested, he gave up his client list, which Teresa and Spider-Man started going through to recover SHIELD tech.

When Spidey explained that Chameleon once used LMDs of their parents to manipulate Peter, Teresa secretly feared that she was also an LMD. She covertly broke into The Hiding Place, the secret prison Chameleon was being kept in. He brought her to a cell where The Finisher, the supposed real killer of the Parkers, could talk to them with his holoprojectors. He used them to reveal the secret history between him and Chameleon. This included showing her the school she was educated in and proving he wasn’t the real killer of her parents. Chameleon also implied he took Nick Fury’s place and planted the evidence that convinced Teresa of her parentage.

Finisher promised to tell her the whole truth if she would steal The Clairvoyant, a device that uses a probability algorithm to predict the future, from Spider-Man. She refused, accepting that she was the real Teresa Parker and vowed to hunt down her parents’ real killer.

Janus Directory

Teresa was tricked into attacking Wolverine by a mysterious foe named Dreadshadow. Dreadshadow had his hands on the "Janus Directory," a cache of records on every covert agent in history. She was fed a doctored video feed of her parents' death which included herself as a baby on the plane that crashed as well as Wolverine, who was made to look like the killer. She tracked him down in New York City and shot him in the chest out of anger.

Wolverine was working with Spider-Man at the time. The same footage was used to turn them Spidey and Logan against each other. Despite Spidey's anger, he chose to work with Logan until Dreadshadow and his team of their rogues was stopped. Dreadshadow teleported to their location to gloat, but when he tried to teleport away, his damaged teleporter exploded seemingly killing him.

Using resources at Rand Enterprises, Peter Parker was able to clean up the doctored footage. He played it for Logan and Teresa. It proved that Logan was sent by SHIELD to protect the Parkers, but he failed. Baby Teresa was nowhere to be seen, and the Parkers last words to each other were only about Peter. This led Teresa to believe that the Chameleon was right about her not being a Parker.
