Author's Saving Throw: Al Ewing in the Immortal She-Hulk one shot basically summed up all of the current issues Jen's having in Avengers with her still reeling from the implications of her own immortality, and sorting out her emotions over the circumstances of Bruce's death as well as Carol causing Civil War II from completely misunderstanding her words before her death... In short, Al Ewing explained that nothing she's been doing as Jennifer Walters OR as She-Hulk has been in her right mind, meaning it's just a bump in the road and anything Jason Aaron does holds no weight for her character.
During Civil War II, Jennifer's death. Made even more raging because it was done by an attack that she has survived before (and her reaction to being hit is borderline Narm). The whole scene has been argued back and forth (alongside Rhodey's death) as an example of Stuffed in the Fridge in order to make Carol's (and Tony's) Well-Intentioned Extremist (and Took a Level in Jerkass) bent more sympathetic than it was on the first Civil War. Thankfully, She-Hulk is alive as of Civil War II #4, although she's understandably not happy...
And then there's the reveal (thanks to pre-order advertisement) that the trauma of being killed/put into a coma and all the crap that happened on Civil War II because of Carol (apparently) misunderstanding her "last words" made her so traumatized that she has devolved into a pure rage-filled, grey Hulk (the relaunch of her series even ditched the "She-" from the title), with the series' creators telling that the thing will be an exploration of how Jennifer is now more like Bruce, seen as a monster and yet still being heroic and her struggles with said trauma... The fact that people love her because she's Fun Personified have taken this quite badly and denounce it as yet another example of Marvel shitting on a character (ex. "Superior Spider-Man" or Robbie Baldwin/Speedball/Penance) for the sake of shock value. However, while Civil War II was savaged by critics and fans, the first two issues of the Hulk series by Mariko Tamaki were actually fairly well received.
Jen losing the "trauma angst Grey Hulk" angle and even getting a power boost to boot... But the trade-off is that now Jen loses some intelligence when she is in Hulk mode, even occasionally using Hulk Speak in a non-joking fashion because that's how "articulate" her form has become. Mention this in a forum and stand back because the fireworks will be nuclear.
The green "Hulk" form, a Brawn Hilda She-Hulk more in line with She-Thing in terms of physical appearance (dubbed by some readers as "The Hulk with Boobs"), that Jen developed as a result of the aforementioned "Gray Savage Hulk" storyline is a highly contentious angle. It has its hardcore defenders, often rallying around the idea that She-Hulk's original design was sexist, but also a large and vocal opposers, whose complaints range from disapproval of the design to those who argue that it's inconsistent with continuitynote The in-universe justification was that Hulk is Bruce's inner monster, embodying his repressed anger and sorrow while She-Hulk was conceived of as Jennifer's inner bombshell, the confident, sexual and fearless woman she always wanted to be. . Aaron himself hit back at his critics in Avengers #20 in an attempt to justify the change in her character. However, Al Ewing's writing of this take on the character has earned a somewhat more positive response thanks to being closer to her more common portrayals, with some lamenting over how he has to stick to Aaron's writing in Avengers instead of being able to fully bring the character back to her roots.
Complete Monster: "Ceremony" (October & November 1989): Carlton Beatrice is the CEO of Carlton Industries who tries to purchase Apache sacred land, Keewazi Reservation, for business purposes. Learning about the Apache people's religious ceremony, Beatrice masters the art of soul stealing. Learning that he lacks the beneficient energy produced by women, he killed an Apache woman who tried to stop him. Learning that the mystic basket that could expand his powers was in the possession of She-Hulk, Beatrice attempts to persuade her, and when his assistant hurts She-Hulk with his spirits, Beatrice punishes him by ripping his soul apart—not because of any standards, but because he needed She-Hulk to give the basket to him to harness its power. To this end, he ripped out her fiancé's soul and used it as a bargain to retrieve the basket. After retrieving the basket, Beatrice performs a ritual to consume all of the souls in Earth to gain more power.
Many people have called the "Grey Trauma Rage" era that she went through in the aftermath of Civil War II this (look up on Broken Base for specifics). Though some see it more favorably than her "Hulk" era and some saw Tamaki's run as an interesting story about trauma, though debate on whether or not it should have been done with Jen.
The "Hulk" era that she entered afterward under Jason Aaron, if considered separate from the above at all, is regarded just as poorly with some fans. Gwenpool Strikes Back briefly lampshades about this direction, with Gwen asking out-of-the-loop readers not to ask why Jen is suddenly depicted with a brutish look than usual.
Foe Yay: Titania is obsessed with defeating She-Hulk. Her husband left her because she was too focused on beating Jen, and she didn't even notice. A Watcher has commented on it. Doc Samson even suggests that her fixation on She-Hulk might be sexual (though this was more to distract her during a fight rather than a serious diagnosis). Even Jen has called her out on it, asking why Titania cares so much.
In She-Hulk Volume #2 Issue #4 of Dan Slott's run, Jennifer declares Bruce Banner has never killed anyone during his Hulk rampages, because if he had he would have committed suicide to keep it from ever happening again. Seven years later in The Avengers film Bruce claims that he can't kill himself, even though he's tried... which was then doubled-down on and made canon to the comics with Immortal Hulk.
In Ultimate Marvel, readers are dealt a Shocking Swerve when that universe's version of Shulkie turns out to be Betsy Ross, rather than Jennifer Walters. Then, in mainstream continuity, we get the The Reveal for Red Shulkie's identity. Guess who again?
My Real Daddy: John Byrne's take on She-Hulk is considered by many to be the definitive run on the character. Dan Slott and Peter David are also viewed as the best She-Hulk writers.
Older Than They Think: Jennifer undergoing a monstrous change in her She-Hulk persona, usually during times of mental stress or physical empowerment, isn't a modern or rare plot point in her history:
Sensational She-Hulk #14 and #15: While teaming up with Howard the Duck for a rescue mission the strange "Baloney-verse", She-Hulk was forcefully changed back into Jennifer after passing through their initial entry point. The next issue has the two attacked, and Jen uncontrollably transformed into The Grey She-Hulk - a very brawny and savage version of herself that talks in Hulk Speak and hates "punny Jen". When The Watcher brought She-Hulk, Howard, and the rescued scientist out from that place, Jen reverted back to normal due to the sunlight but in issue #16, she would transform back into The Grey She-Hulk when it became night. The residual gamma radiation in the hot springs would turn her back into her customary self, but with a grey skin tone instead of her usual green.
40 issues later in the same Sensational She-Hulk run, Jennifer was revived after succumbing to the fatal powers of Rumbler. When Rumbler tried to kill her father, Jennifer intercepted and hulked out further, undergoing a bulkier and harden savage◊ look once more. Though she was still green and spoke intelligibly, her behavior was far more abrasive and reckless.
Tough Act to Follow: The Marvel Now! series follows on the much-praised Dan Slott run, and shares more than a few elements with it in terms of story. Unfortunately many found that it lacked the humour, art and action that made that series a success.
