She-Hulk episode 1 when a Sakaarian spaceship causes Jennifer Walters to crash her car, setting the entire series into motion.
While Bruce Banner/Hulk has not spoken much about his time on Sakaar, it is reasonable to assume it was not a pleasant experience. Once Thor helped him to return to his form as Bruce Banner, and he realized that he had injured or even killed people purely for entertainment, Hulk was ashamed and angered. While it is not explicitly stated how or why he was kept in his Hulk form on Sakaar, it is explained that time es differently on Sakaar. This means that while in Earth-years he was only on Sakaar for two years, Bruce was the Hulk for thousands of years, as per Sakaar's relative timeline. This could also explain Skaar’s teenage appearance when Hulk introduced him at the end of She-Hulk's finale. The introduction of Skaar clearly shows that more happened to Hulk during his time on Sakaar than audiences previously thought. Within that span of time, Hulk may have also developed a romantic relationship - possibly before Thor helped him transform back into Bruce Banner and escape Sakaar.
Why Hulk Would Go Back To Sakaar After What Happened To Him
When the Sakaarian spaceship appeared in She-Hulk fans theorized that it was connected to Hulk’s time on the planet. When Hulk is next shown, he is on the spaceship heading for an unknown location which was presumed to be Sakaar itself. While it is a possibility that Hulk returned to Sakaar after the events of Ragnarök and before the events of She-Hulk, it is also possible that he hadn't stepped foot on the planet due to the trauma it caused him. Something - or someone - very near and dear to his heart would have to convince him to go back. At the end of She-Hulk episode 9, Hulk states that he knows he has been gone for a while on Sakaar and that’s a story for another time. Then he proceeds to introduce his son, who is dressed similarly to Hulk’s Sakaarian gladiator gear seen in Ragnarök. It is likely that Hulk did not know that Skaar even existed until Skaar himself sent a spaceship to Earth in an attempt to his father.
Didn’t Hulk Say It Would Be "Impossible" For Him To Have Children?
One lingering problem is that in 2015’s Age of Ultron, Hulk discusses the possibility of children with his then-lover Natasha Romanoff. While he had only a short-lived Caiera is Skaar’s mother.
Skaar, Caiera, and the future of World War Hulk
Audiences have been hopeful for a proper Hulk movie soon in a conversation with the AI creation K.E.V.I.N., a metatextual nod to Kevin Feige, when he insisted on keeping Hulk in the finale. To this, She-Hulk laughed, claiming he should “save it for the movie.”
Hulk’s son was one of many surprises in the season finale of She-Hulk and certainly a big one to unpack. It appears that with the introduction of Skaar, there will finally be some clarity about what truly happened during Hulk’s time on Sakaar, further expanding on Hulk's character who has largely remained a mystery, despite his 15 years of involvement in the MCU. While it remains to be seen what Skaar’s involvement in the MCU will be - as well as if or when he will appear in future storylines - the reveal of Skaar was nonetheless an exciting way to end the first season of She-Hulk: Attorney at Law.
All episodes of She-Hulk: Attorney at Law are now streaming on Disney+.
