Jennifer Walters: Maslany gives a "witty, humble, and conflicted" performance. 4th wall breaks start out as subtle, but by the end literally change the conclusion of the series. The scene in question consists of She-Hulk "bursting" out of the screen and rewriting the episode with the help of Kevin Fiege. "Plenty of the jokes landed, but some fel
kinda low brow. Sometimes it feels like Harvey Birdman and other times it feels like typical MCU humor."
Bruce Banner: Bruce shows up as a post credit scene in episode one and then disappears until they address how Jennifer obtained her abilities. There is an entire origin episode late in the season, which is where the clip from the Disney+ day is pulled from. Mark is fully Hulked out for the season, besides a short car ride sequence. His performance feels similar to that of Prof Hulk in Endgame. Hulk's son, Skaar, is revealed towards the end of the season.
Emil Blonsky: Tim Roth kills as Emil. He spends the majority of his time in human form as he is up for parole and under surveillance at the Raft. Jen has been assigned to her case and they befriend each other so he can get out and start a retreat in the mountains for various low tier villains and other side characters. Tim is quite comedic. "The ending I saw felt like a bit of a placeholder for Emil as they did not really address what came of him. So, there may be multiple scenes floating around at various stages of the process."
Titania: She is an influencer of sorts. At one point she tries to sue Jen for the use of "She-Hulk".
Matt Murdock: Daredevil is in two episodes. Jennifer takes a case against a superhero tailor, and Matt is the defense attorney for him. Murdock totally schools Jen and they go for drinks, hit it off, and he offers Jen a spot in Hell's Kitchen with his firm. They later fight due to a mixup but wind up teaming up and eventually sleeping together. There is a scene where they are making love on a couch and Wong portals in for help. He is very much the same Matt Murdock from the Netflix series. He is wearing a yellow and red suit; the yellow is darker and more subdued than the comic version. They are setting up Daredevil as a MAJOR player. He will be in both Moon Knight and Echo, and from what our source understands he will also be in Iron Heart and Armor Wars.
Jessica Jones: Jessica Jones does not appear in She-Hulk, unless they are keeping it tightly lipped
Thunderbolts: Heavy Thunderbolts references and Red Hulk teases. William Hurt was on set and filmed some scenes.
Intelligenica: Group of "women-hating incels" who have synthesized the Hulk gene and injects it into their leader. He is a knockoff Hulk with awkward proportions.
Jim Carrey: Jim Carrey was on set and filmed something. Our source originally thought it was MODOK and there is a chance he was originally and they change actors. However, Carrey filmed heavily in mocap for multiple projects. His part from She-Hulk could have been cut
Various Cameos: Man-Bull, Baron Blood, and Porcupine are all at Emil's mountainside retreat. Mr. Immortal is a client of Jen's firm handling multiple divorce settlements. Wong shows up in court to defend Emil at one point. Wong has a decent sized role in the show
Fun Fact: It is learned the Steve Rogers lost his virginity to a USO girl back in the 40s. Most episodes have post-credit scenes. Some are silly, like Wong watching The Sopranos, and others are huge cliffhangers, like Bruce flying off in a spaceship
