She Hulk
ennifer Walters is an American lawyer who, after being shot by a mobster, was saved by a blood transfusion from her cousin Bruce Banner (aka the "Hulk"). Banner's gamma-irradiated blood mutated Jennifer Walters into the sensational She-Hulk, and kicked off her adventuring career.

History

 * I never wanted this to happen, but now you have to learn the other part of being a Hulk. The part where the people you fight to protect sometimes fear and hate you. And it's the hardest part because sometimes to protect what you love, you have to walk away from it.

Early Life
Jennifer Walters was born and raised in Los Angeles, California. She was the daughter of Sheriff Morris Walters and Elaine Banner-Walters. Growing up she was meek and mousy and had little confidence. Jen later attended UCLA (University of California, Los Angeles) where she gained her law degree. She began working as a lawyer in Los Angeles.

Jen was also the cousin of Bruce Banner, whose house Jen used to visit during the summers of her childhood. To help him escape from his father's abuse, Jennifer and Bruce would spend hours in a public library, reading books to each other and sometimes hiding at closing time to spend the night.

Blood Transfusion
Agents of Nicholas Trask, a crime boss who had crossed paths with Jen's father, shot and seriously wounded her on a day when her cousin Bruce was in town. She had been defending a gangster who had been double-crossed by Trask and offered to turn state's evidence, which would be sufficient to ruin Trask if the case went to trial. Bruce fended off the attackers and then broke into a doctor's office to treat her. Realizing Jennifer was going to die, Bruce gave her a transfusion of his own blood as there were no other supplies in such an emergency.

After she stabilized, he had her admitted to a local hospital. However, this came to the attention of the police, who considered Bruce a suspect in Jennifer's attack and Bruce changed into the Hulk to flee. Meanwhile, Trask's thugs attempted a second hit on Jennifer, causing the danger to activate gamma radiation particles in the transfused blood, turning her skin green and increasing her size to well over six feet. The goons were taken aback at what happened, and commented "it's some kinda she-hulk". Jennifer's voice boomed out "You called me a She-Hulk, so that's what I'll be," and trapped the thugs for the police to find. With the emergency over, she reverted to her normal size and strength.

She-Hulk
Although Jennifer was at first savage while in her She-Hulk form, she eventually gained the same intelligence that she had as the normal Jennifer Walters. She quickly came to appreciate the confidence and assertiveness that came with being the She-Hulk. For a long time, she felt more comfortable in her She-Hulk form than her human one. Trask paid off a local trucker to keep quiet about a shipment coming in from Stark Industries containing advanced technology. He had the trucker killed as well as the men turning state's evidence, laying the blame on the She-Hulk. He tried to kill Jen again but ended up killing Jill Ridge. The contents of the crates were revealed to be robotic parts to which he built a "She-Hulk Robot," but she was able to destroy it. Trask abducted Sheriff Walters, giving him more advanced weaponry from Stark Industries to kill the She-Hulk, keeping him ignorant that she was his daughter. Trask even rigged it so it would explode killing them both.

She-Hulk spotted the flaw and saved herself and her father. Trask next constructed a massive earth-boring device called the "Silver Serpent" using the Stark tech. He planned to drain Roxxon Oil dry, allowing him to buy out the company. She-Hulk investigated and discovered the machine, but during the fight the drill continued to bore deep and deep in the Earth burying Trask alive.

Avengers
After a brief solo career (during which she met Hellcat),Jen joined the Avengers. This led to her being transported to Battleworld by the Beyonder and her participation in the first Secret Wars, most notable to her for sparking a long-standing rivalry with the newly empowered Titania.

Fantastic Four
She temporarily replaced the Thing in the Fantastic Four after the war on Battleworld. She-Hulk was granted detached membership status with the Avengers upon joining the FF.

During her tenure with the Fantastic Four, the She-Hulk had to prevent a radiation leak in a downed S.H.I.E.L.D. Helicarrier. This radiation exposure apparently mutated Jennifer to the point that she could not transform back into her original form. But this was an agreeable turn of events for her since she preferred her She-Hulk form anyway. Shortly after that, she appeared before the Supreme Court, where she battled Titania.

Rejoining the Avengers
After the Fantastic Four, She-Hulk rejoined the Avengers following the Masters of Evil's attack on the mansion. During this tenure with the team, She-Hulk and the other members were influenced by Doctor Druid and his lover, Nebula, to appoint him chairman of the team. After Druid and Nebula were lost in space-time, She-Hulk and the two remaining members disbanded the team for a time. Jen eventually returned to the group after Captain America restarted the Avengers.

She-Hulk joined the staff of District Attorney Blake Tower, where she met Louise "Weezi" Mason, formerly the Golden Age superheroine called the Blonde Phantom; during this period, she discovered that Mason had manipulated Towers into hiring She-Hulk so that Mason could again star in a comic book and thus avoid dying of old age. Mason's husband, also a former comic book character, had passed away three years ago, but other, more popular characters from the era, such as Captain America and Namor the Sub-Mariner, were still around.

Fantastic Force
She-Hulk was a member of the short lived hero group the Fantastic Force.

Heroes for Hire
Later, while doing some legal work for Heroes for Hire, she also went on a few adventures with them and spent some time dating Luke Cage.

Back With the Avengers
Eventually, Jen returned to the Avengers and remained with the team for some time. On one adventure, the She-Hulk was exposed to fellow Avenger Jack of Hearts' radiation powers, causing Jen to lose control of the savage side of her personality. She injured several Avengers and went berserk in Bone, Idaho, virtually destroying the whole town. With Jen's fear and rage at an all-time high the assembled Avengers couldn't stop her. Only the Hulk himself was able to slow her down until Jack of Hearts was able to use his powers to balance her gamma levels and she regained control over her savage side.

Goodman, Lieber, Kurtzberg, & Holliway
Jennifer's Avengers status eventually conflicted with her work at the DA's office, and Tower let her go. She was hired as a lawyer for the Superhuman Law division of the New York firm of Goodman, Lieber, Kurtzberg & Holliway. While training for a bout against the Elder of the Universe known as the Champion, Jen increased her strength level phenomenally. She took to wearing a modified version of John Jameson's Jupiter Suit to keep her strength under control.

Jen thought she developed enough control to operate without the Jupiter suit, but her worst fear came true when Scarlet Witch went temporarily insane and used her magic to cause Jen to lose control again. This time, she nearly killed Captain America and tore the Vision in half with her bare hands.

Although she had been manipulated, She-Hulk was devastated at her part in the Vision's death and the destruction of the town of Bone, Idaho. Ashamed, She-Hulk quit the Avengers to resume her law career and spend more time as plain Jennifer Walters.

Civil War
During Civil War, she was able to change forms at will again. Jennifer rediscovered she sometimes had wildly different views and opinions in each form, where as the She-Hulk she came out publicly in favor of the Superhuman Registration Act, as Jennifer Walters she understood the views of those against the Act. Before the war really started, Jen and John Jameson, who she met when he was the Wolf-Man, precipitously eloped in Las Vegas. This relationship did not last long as she later learned that Starfox, whose mind had been damaged by his brother Thanos thus affecting his powers, had made Jennifer love John as he loved herwhich led her to seek an annulment.

For a short time the Registration Act was used to have Jennifer be an Agent of S.H.I.E.L.D. and work alongside the Hulkbusters while her cousin Bruce was 'missing'. During this time she was under the command of Clay Quartermain, whom she also slept with, and was ordered to fight the Abomination in Reno. Jennifer also fought a Wendigo alongside Wolverine who she hit on, though he was uninterested as he believed she had slept with Juggernaut. Jennifer and the Hulkbusters went on to capture many of the Hulk's rogues gallery for a S.H.I.E.L.D. operation known as 'Project Achilles', including Zzzax who escaped and began influencing the S.H.I.E.L.D. Helicarrier's systems while Jennifer was in bed with the current director Tony Stark, leading her to fight an army of Nick Fury LMD's in her underwear.

S.P.I.N.
She-Hulk discovered that S.H.I.E.L.D. knew of her cousin's whereabouts after sending him off into space and went to confront Stark, leading to a fight where she compared him to Doctor Doom and he injected her with S.P.I.N. Tech, the second phase of Project Achilles, that inhibited her powers and knocker her out while turning her back into her human form. During World War Hulk, Amadeus Cho temporarily restored her powers and she defeated Doc Samson in battle. Later Tony Stark temporarily restored her powers so she could help evacuate New York City. She tried to convince the Hulk to stop his attack, but she was defeated and held captive with the other heroes at Madison Square Garden, which the Hulk had converted into a gladiatorial arena.

Stark then turned her powers back off. Jennifer then regained her powers after having the nanites in her system removed by Reed Richards, using a device designed to let people from Earth A have their atoms realigned with their superpowered Earth-616 counterparts.

Bounty Hunter
After having her powers returned to her, Walters began operating as She-Hulk again. During this time she was disbarred from her position as a lawyer and began working freelance for Freeman Bonding Inc, a subsidiary of her law firm, as a licensed bounty hunter alongside the daughter of the Super-Skrull Kl'rt known as Jazina. Walters was tasked with bringing in the cousin of the Absorbing Man Carl Creel, Rocky Davis, after he skipped on his bail and had to fight the Absorbing Man who Rocky was hiding out with. During the fight Creel's miniaturised wife Titania slipped into She-Hulk's ear to attack her from the inside while the fight spread to a nearby mall. She-Hulk managed to get the upper hand in the fight again when a blow from Absorbing Man's Ball and Chain knocked Titania out of her ear and She-Hulk was able to defeat Creel with help from Jazinda who was posing as 'Jennifer Walters'.

At this time Jennifer and Jazinda were both living in RV's parked in Dona Little's Trailer Park. After getting paid for bringing in Rocky Davis, She-Hulk went for a drink at a bar where she was approached by Bran Murphy, a man she had never met before who charmed her before detonating a bomb in an office building across the street. She-Hulk and Jazinda tracked the bomber to Cleveland, Ohio. On their way, while driving through the nation park of Allentown, Pennsylvania, they were seemingly attacked by a spaceship though they quickly learned that the occupant, Cazon an alien Froma from the gamma irradiated planet Chize had mistook She-Hulk for one of his people and was seeking their help. She-Hulk did not want to help him as had given up on being an altruistic hero, though she did intervene when Cazon was attacked by a Badoon. Cazon turned out to be a mass murderer who attempted to kill Jazinda after murdering a civilian woman, after a brief battle with the Badoon bounty hunter who was after Cazon, She-Hulk helped him to capture the killer although Jazinda then killed him herself.

She-Hulk and Jazinda carried on their way to Ohio in search of Bran Murphy but had to turn around and go back to Allentown, after Larry Ryan the husband of the woman murdered by Cazon was arrested on suspicion of killing her. She-Hulk hoped to explain the situation and get Larry out of jail but was herself arrested when the Allentown Police Department misunderstood and believed she was breaking him out, after she accidentally damaged his cell. Jennifer called and begged Mallory Book to represent Larry, who she was able to prove to the court was innocent after calling Tony Stark in to testify that Ryan's wife truly had been murdered by an alien.She-Hulk and Jazinda finally tracked Bran down to Cleveland, where she wound up arrested again after confronting Bran at the Cleveland Browns Stadium where Bran was serving as a bodyguard for Arthur Moore, who had a restraining order against She-Hulk and who was the man who got her disbarred and who had been with Bran for the past week when She-Hulk saw him in New York with a different accent and tattoo.

She-Hulk then revealed to her cellmate Monique, a woman who was arrested for beating a man who tried to sell her seven year old daughter heroin, what had led to these events including why she was operating as a bounty hunter rather than a lawyer. She-Hulk had been hired to represent Arthur Moore while working for GLK&B after she regained her powers. Moore had used his talismans to rob first national bank as well as charges for animal cruelty and was suspected of being involved in local cases of missing children. She-Hulk successfully argued Moore out of the charges, after which Moore used his magic to show both She-Hulk and Mallory Book an illusion that he was indeed guilty and had ritualistically sacrificed the local missing children after turning them into animals, as this information was provided to them under attorney/client privilege they were unable to do anything with what they then knew. Moore had been purposefully goading She-Hulk so as to get her to attack him so that he could 'destroy her' by getting her disbarred, which happened after she revealed to reporters who witnessed the fight what she knew of Moore's crimes. The children were then found prisoner in a cabin in upstate New York, Moore having used the illusion solely to provoke She-Hulk.

She-Hulk was released from jail and the charges were dropped against her after Moore was murdered and the District Attorney's office wanted her help, she agreed to help them on the condition that Monique also be released with her charges dropped. She soon learned that Moore's murder was not the only reason she had been released, a giant sized Bran Murphy was also being chased through the city of Cleveland by an enraged Hercules who was a wanted man at the time. She-Hulk learned that Bran had been playing host for Bendigeidfran 'Bran' the Blessed, a Celtic god who Hercules stopped via decapitation. She-Hulk then broke her personal vow to refrain from playing 'sexual pinball' by sleeping with Hercules.

Secret Invasion
Jazinda clued Jennifer in to the fact that Skrulls were hiding on Earth and that their Secret Invasion was imminent, together they began tracking Nogor the Talisman, a Skrull representing the Skrull Gods who was impersonating Longshot, and who Jazinda had sensed the presence of as all Skrulls could. This investigation led them to Detroit, Michigan where the Skrull was travelling with Armando Muñoz, the mutant known as Darwin, who was unaware that his companion was a Skrull and who interfered when Jazinda attempted to apprehend Nogor when he recognised her and tried to run. X-Factor Investigations were headquartered in Detroit at the time and became aware of these events, leading one of their members, Monet St. Croix, to fight Jazinda and She-Hulk.

Monet made an attempt to diffuse the situation and work to understand what was going on, but She-Hulk preferred to fight, partly to allow Jazinda to continue after the disguised Nogor. She-Hulk was able to hold her own against Monet until one of Monet's X-Factor teammates, Guido Carosella, arrived to aid her. While this fight was happening, Jazinda managed to catch up Nogor, whose safety was paramount to the Skrull Army maintaining their moral and belief that their actions were righteous. Darwin attempted to defend Nogor, who he still believed to be Longshot, causing a blast from Jazinda's gun to ricochet off of his body and into her. Meanwhile, She-Hulk had defeated her opponents but was then accosted by Jamie Madrox, who used his duplicating power to give her an entire mob to fight against. While She-Hulk was being kept busy Monet located 'Longshot' and Darwin, telepathically scanning 'Longshot' and finding nothing to suggest he might be a Skrull, though Darwin's powers revealed him moments later.

She-Hulk was able to defeat Madrox and contact Jazinda, whom she learned was still on Nogor's trail. She-Hulk and Jazinda then teamed up with X-Factor to fight the exposed Nogor, who was trying to recruit Darwin to the Skrulls side. While Nogor was distracted by Darwin, She-Hulk was able to hit him which gave Jazinda a chance to place a device on him to nullify his powers. Jazinda and She-Hulk were transporting Nogor through Minneapolis, the two of them wanted to use Nogor to try and stop the Skrulls but were unsure of who they could trust on Earth, while discussing their options they spotted a Skrull ship transporting humans, which She-Hulk took down. After liberating a smaller vessel from the Skrull ship they were met by Jazinda's father Kl'rt the original Super-Skrull who had Jazinda down to kill her as he had promised, unaware that she was travelling with She-Hulk who defended her when Kl'rt attacked. During the ensuing fight, She-Hulk and Kl'rt were thrown from the vehicle while Nogor got free and attacked Jazinda.

During the ensuing battles between the four, the Super-Skrull killed his daughter but decided to prevent Nogor from removing the Gem from her body to prevent her resurrection, after She-Hulk talked some sense into him, before throwing Nogor some distance away and leaving before Jazinda could return to life.

Red Hulk Saga
Jennifer tasked Ben Urich to discover the identity of the Red Hulk. While She-Hulk went M.I.A. following a battle between the Hulk and the Red Hulk, a Red She-Hulk appeared claiming Jennifer Walters was dead. It was later shown in a flashback that Red She-Hulk prevented Jennifer Walters from escaping from AIM custody. During this battle, Red She-Hulk brutally beat Jennifer and snapped her neck with a cable. Though the Red She-Hulk claimed she didn't know her own strength and questioned Doc Samson whether it was the real She-Hulk or a Life-Model Decoy, to which Samson answered "You're here to follow orders, not to ask questions". Lyra later infiltrated the Intelligencia, where she found Jennifer in stasis.

She-Hulks
After the defeat of the Intelligencia, Jennifer took Lyra to live with her in New York. During a charity event, she spotted the newly-rebuilt Vision and promptly sought to make amends with him due to her being driven to her primal Hulk state and tearing him in half as part of one of the times Wanda lost her grip on her sanity and control of her powers. They had a brief conversation, where she expressed her regret for what happened, and Vision forgave her. She then told him not to get mad at Wanda before leaving.

Fearsome Four
During Fear Itself, Jen formed a team called the Fearsome Four with Howard the Duck, Frankenstein's Monster, and Nighthawk to stop the Man-Thing who found himself driven to an uncontrollable rage, caused by the immense levels of fear generated by the Serpent's hammer-wielders across the globe. Facing various alternate universe heroes and the Psycho-Man, brought to Earth by the Man-Thing's connection to the Nexus of All Realities, the four were eventually able to confront their own fears and calm the Man-Thing, bringing an end to his rampage and saving the world before going their separate ways.

Avengers vs. X-Men
Jennifer sided with the Avengers in the conflict against the X-Men and was sent to keep an eye on the Jean Grey School together with Moon Knight and Falcon after some of the school's teachers decided to join Cyclops. A fight soon broke out as Frenzy goaded Moon Knight. Jennifer seriously injured some kids who tried to attacked her which led to the rest of the school's faculty attacking them as well.
