Jonathan Majors Cast as Kang the Conqueror in Ant-Man 3
The star of Lovecraft Country Jonathan Majors has reportedly been cast as the Fantastic Four villain Kang the Conqueror. However he is not debuting for a MCU Fantastic Four film. In fact he will be appearing in the upcoming Antman 3. As King the Conqueror is a time travelling villain, it's likely his time travelling will tie into the Quantum Tunnel from the Antman films which the Avengers used to travel into parallel past timelines.
Jonathan Majors being cast as Kang may lead to a certain Fantastic Four member being portrayed by an African American as Kang's real name is in fact Nathaniel Richards. See where we are going with this? Well Nathaniel is believed to be a 31st century descendant of a Dr Reed Richards aka Mr.Fantastic, leader of the Fantastic Four. Nathaniel is also believed to be a descendant of Dr Victor Von Doom... somehow. Not only that Kang has many popular doppelgänger counterparts from other timelines like IronLad and Immortus. So with the introduction of this character it may lead to a build up for the Fantastic Four and possibly introduce a member of the Young Avengers.
