Who is King Stark's son?

The term "King Stark" doesn't refer to any character in the official Marvel Comics canon, but it might be a reference to the Stark family, particularly Tony Stark (Iron Man), in alternate realities or stories. If you're asking about a son of Tony Stark in a specific storyline or universe, there are a few possibilities to consider, especially when we look at alternate realities or non-canon stories.

1. Tony Stark’s Son in the Comics:

In the Marvel Comics universe, Tony Stark has not had any permanent biological children in the main continuity (Earth-616). However, there have been alternate timelines and universes where Tony Stark has had a son or a child figure:

• Iron Man 2020 (Arno Stark): One of Tony Stark's relatives is Arno Stark, who appears in the alternate timeline of Earth-8410 (Iron Man 2020). While Arno is often considered a cousin or distant relative rather than a direct son, he plays a significant role as a Stark heir, though his character is far more villainous in many storylines.

• Riri Williams (Ironheart): While Riri Williams is not Tony Stark’s biological daughter, she is often considered a spiritual heir to Stark. Riri is a young genius who builds her own version of the Iron Man suit, and in some stories, she is seen as the successor to Tony Stark's mantle as Ironheart. In a sense, you could say that she is a daughter figure to Tony Stark in terms of legacy, though not his biological child.

2. Tony Stark's Son in the Marvel Cinematic Universe (MCU):

In the MCU, Tony Stark does have a daughter, Morgan Stark, who appears in Avengers: Endgame (2019). Morgan is the daughter of Tony Stark and Pepper Potts. However, Tony does not have a son in the MCU as of now. Morgan Stark represents the closest thing to a "Stark heir" in the MCU.

3. The Future and Alternate Realities:

• Marvel's "What If" Series: In some alternate realities explored in Marvel's "What If" series or other multiverse stories, different versions of Tony Stark have children, and their legacies sometimes take different forms. These stories allow for the possibility of a son in a reality where Tony might have had a son instead of a daughter.

• King Stark in the Comics (Alternate Realities): In some storylines, especially in the Ultimate Universe (Earth-1610) or other alternate timelines, Tony Stark's legacy is explored through different versions of his family. In one particular storyline from the Ultimate Marvel universe, a son of Tony Stark, Tony Stark Jr., plays a role in the narrative. However, this version is not directly labeled "King Stark" or a kingly figure.

Conclusion:

While there is no canonical "King Stark" or a biological son of Tony Stark in the main Marvel continuity, there are many alternate realities and timelines where Tony has relatives or heirs. In the MCU, Tony Stark's daughter, Morgan Stark, is the closest we have to his child.
