The She-Hulk: Attorney at Law finale had so much going on, that the surprise introduction of a major character at the very end almost did not pack much of a punch, perhaps because it has been rumored for quite some time. Still, the brief introduction of a new character likely has major implications for the Marvel Cinematic Universe going forward.
At the end of the She-Hulk finale, Bruce does eventually show back up (granted, he was axed from the messy climax after Jen went to clear things up with Marvel Studios). At the Walters’ family picnic, however, Bruce arrives with someone else in tow: his son, Skaar. For those unfamiliar with Skaar from the comics, this could be a wild twist. In general, it is a major inclusion in the MCU that will surely carry a lot with it. So, first, who is Skaar? And second, what does his presence mean for the MCU now?
In the comics, Skaar comes from a relationship the Hulk has while on Sakaar. He conceived a son with Caiera the Oldstrong, but after a ship explosion that killed Caieria, the Hulk believed that Skaar had died in the womb. Obviously, Skaar did in fact survive and was raised by his mother’s Shadow People on what was left of Sakaar. Eventually, he was exiled to Earth. And when he arrived, all he wanted to do was kill Bruce.
In live-action, it is not hard to imagine that something similar happened and our MCU Hulk fathered a child on Sakaar. We have a lot less information on who Skaar’s mother might be, the state of Sakaar, or why Skaar has come to Earth, however. The way his arrival was set up in She-Hulk, it almost came across as though Bruce went to Sakaar knowing that he had some sort of responsibility—maybe Skaar. It is also very likely he was not aware of Skaar before his return to the planet. In any event, he definitely brought his son with him and they seem chummy enough.
The most obvious prediction for how Skaar will factor into Phases 5 or 6 is as part of the rumored ‘World War Hulks’ project. She-Hulk seemed to tease that it could be part of the setup for that project or overarching storyline, given the Hulk blood fascination. The series did not end up going that route, but the implication is very clear: the MCU is about to get more hulks. What happens when the MCU gets a bunch of hulks?—probably some type of World War Hulk iteration. Skaar plays a significant role in that story, but the theories on how Marvel Studios might adapt it so far are endless since we are seemingly at an early stage of that process. However, given the casting of Tim Blake Nelson as The Leader in Captain America: New World Order, that movie might be a solid place to start.
