Likely yes. So far he has only shown up for a very brief scene in the final She-Hulk episode.Damn I gotta catch up on the MCU.
Bruce has a son in the MCU!? Is his story at all similar to his son in the comics?
About mid-way through the season, Bruce leaves in a spaceship for an at-the-time unknown reason. I don't recall if it's stated that he's going to Sakaar or not. And in the final episode, at a family dinner, he shows up again with son in tow. I don't think the lad in question has any lines.
I'd add that I think the idea of Hulk having a son from his time on Sakaar in the MCU is significantly creepier than in the comics. In the original Planet Hulk story, the "Green Scar" incarnation of Hulk is fairly intelligent. I'm not sure if he's Banner-smart, but he's definitely at least on the Joe Fixit level. And as the Green Scar, he falls in love with an alien lady and gets her pregnant before she's blown up by a malfunction in the spaceship that brought him there, but unbeknownst to the Hulk the child survives in some form of cocoon.
But the Hulk we see in Thor Ragnarok is mentally still a child. The reason this version of the Hulk is not quite as mindless as the one in the Avengers is that he's been Hulk constantly for several years, and has been developing mentally through this time – but he's still not an adult mentally. So either Sakaar is the result of genetic engineering, or someone took advantage of the Hulk in a reduced mental state.
