The whole Kang thing is so strange. First of all, he's a lot better villain than Thanos but they really dropped the ball on him. Kang can switch bodies and switch his appearance so he could have been the bad guy in years worth of movies before they revealed it was the same guy.

but if you can switch appearances, why stick with a black guy? If you're a villain wouldn't you want to look like someone that doesn't commit crimes? Everyone's going to suspect him right away.

Case in point- the actor playing him

and if you can travel through time and get their knowledge and tech like Kang can, why not maybe stop niggers from being the bottom of the barrel in every era and every timeline?
