The MCU wanted Kang the Conqueror to be the next Thanos, but I'm still not convinced he killed Thor as he said he did. Originally, Marvel's Multiverse Saga was centered around Kang as its main villain. When it was first announced, Avengers: Doomsday was titled The Kang Dynasty, but several factors led to Marvel pivoting to Doctor Doom. Ant-Man and the Wasp: Quantumania underperformed with audiences, hinting that viewers weren't invested in Marvel's Kang storyline. Jonathan Majors' legal troubles also left the studio in a challenging position about what to do with the character.
