After having been found guilty in 2 out of 4 charges by a six-person jury, Jonatham Majors has been fired by Disney/Marvel Studios. Majors was found guilty of reckless assault in the third degree and guilty of harassment. He was found not guilty of intentional assault in the third degree and not guilty of aggravated harassment in second degree.
Couple things;
1: Kang was trapped in the quantum realm with nothing. The thing that makes Kang personally dangerous is his technology. This was his “built an iron man suit in a cave” movie.
2: the ants had created a type-2 civilization and, were they hostile to earth, would literally be an avengers level threat on their own.
It took 3 Ant-People, a futuristic army of cyborg ants that can build Dyson spheres, the betrayal of a war machine Kang built, and no small amount of luck (and capitalization on Kang’s arrogance) to win.
I don’t much care if you like the movie - we all have our own preferences - but he was definitely not just a throwaway villain in it. I’m a big Kang fan and they definitely did Kang justice, even if people didn’t like the movie itself.
Plus his whole purpose in the overarching story was to lead into the eventual collapse of timelines, also mentioned in Multiverse of Madness, which is why Kang does what he does.
