In the latest episode of She-Hulk, we again got a glimpse of Smart Hulk. He was talking to Jen about Emil Blonsky aka Abomination and how he got a letter from Blonsky apologizing for his actions with a heartfelt haiku. He also makes a funny joke about how he is not the same person he was when he fought the abomination, quite literally. This joke is referring to the fact that Bruce Banner was re-casted from Edward Norton to Mark Ruffalo. Suddenly the phone call gets disconnected. This is because the Hulk is in outer space. He is aboard the Sakaaran courier craft that we had seen before. It seems like Marvel is planning to have Hulk cameos in every episode. So what is the bigger picture here? Let us explore the possible storyline MCU is setting up for the big green guy.
As seen in the second episode, Bruce is headed to Sakaar. Now, comic book fans will know about Hulk’s relations in Sakaar. He actually had a son with Caiera the Oldstrong known as Skaar. The Sakaaran courier craft could be sending Hulk a message about the birth of his son. In fact, in the comics Skaar hates his father and wants to kill him for abandoning him on planet Sakaar.
Another connected possibility is that the MCU is setting up the storyline for World War Hulk. This storyline follows Hulk as he is exiled from Earth by the Illuminati and spends time on Sakaar, getting stronger and preparing to take his revenge on the Illuminati. Basically, he sought for vengeance on the Illuminati as he blamed them for the death of his wife and child. He eventually returned to Earth and wreaked havoc, fighting his friends and allies as well. Hercules was also a part of this storyline. As a result, MCU could also bring back Hercules after his brief appearance in Thor: Love and Thunder. Moreover, Marvel Studios is most likely in the process of getting back the rights to Hulk. This might very well be a sequel project. Mark Ruffalo has also openly expressed his readiness and excitement for whenever MCU decides to go ahead with it.
