The casting of David Jonsson, 32, as the new Black Panther in "Black Panther III" (2028) has sparked a fan theory about how the Marvel Cinematic Universe will handle a major time jump. Jonsson will play T'Challa's son, first introduced as a young boy at the end of "Black Panther: Wakanda Forever", but the character's age doesn't add up unless a significant amount of time passes in the upcoming "Avengers: Doomsday" or "Avengers: Secret Wars" films. This suggests the MCU may be preparing for a dramatic reshaping of its universe, echoing a well-known Marvel comics storyline.

T'Challa's son, known as Toussaint, was around seven years old when introduced in 2022's "Wakanda Forever", meaning he would be roughly 14 by the time "Black Panther III" arrives in 2028. Since Jonsson is clearly not playing a young teenager, the article argues a time jump must occur during "Avengers: Secret Wars" (2027), likely inspired by the 2015 comic series of the same name, in which Doctor Doom remakes the Marvel multiverse into a single new reality called Battleworld. This mirrors how Marvel Comics previously used "Secret Wars" to simplify an overly complex multiverse, suggesting the MCU could use the film for a similar creative reset.
