She-Hulk: Explains How The Hulk Got His Arm Back

As UCM fans will remember, Gamma radiation was what allowed the huge green-skinned avenger to survive after being able to use the power of the Infinity Stones, although this left him with serious, apparently irreversible consequences. For this reason, Ruffalo’s reappearance in the series starring his cousin, Tatiana Maslany’s Jennifer Walters, in his human form has been a surprise to the fandom. Even more surprising, however, was seeing him with his arm completely healed after using the Infinity Gauntlet in the battle against Thanos. The last time Marvel fans saw Banner was during his brief cameo in Shang-Chi and The Legend of the Ten Rings, where he was wearing a sling on his right arm.

Of course, the question that arises now is: How was this possible, if he could not leave his state as the Hulk with an injury that, at the time, seemed permanent? The answer to this intriguing question has been completely resolved in She-Hulk Episode 1. At the beginning of the episode, Banner tells Jennifer that the jamming device on his wrist is an invention of his own making that allows him to maintain his human form and transform into the Hulk. Being now two completely separate entities, he discovered that, in that state, unlike his hulking counterpart, his wounds did heal, which would explain why the character appeared in Shang Chi as Bruce Banner and not as the Hulk ready.

And while it’s true that her device might have sped up her healing process, what ended up completely healing her arm was Jennifer’s DNA after her cousin’s blood intermingled with hers. In fact, after transforming into She-Hulk for the first time, she discovers that they both share a unique combination of genetic factors that allow them to assimilate gamma radiation.

However, they seem to do it differently. For that reason, Bruce begins to investigate how the radiation in her blood has affected her genetic structure and thus be able to find out how to help Jennifer after she unintentionally becomes a Hulk it is thanks to his findings that Banner manages to heal his arm injury. Of course, even though the chapter does not show how he does it, nor does it offer more details about it, the most plausible explanation is that he took a sample of his cousin’s blood, which seems to have a high healing factor and the will use on himself to fully recover from his injury.
