Make a communist villain/antagonist, but make him/her/them have many good points and have a good amount of sympathetic traits that even the in-universe heroes/protagonists even concede that they have good points, also try not to make said character do a “randomly blows up a hospital for no reason to remind everyone their a villain/antagonist” trope because that’s dumb, just for a bit of a challenge. Also, you can make them like a reflection/allegory of communists as a whole without the demonization capitalist propaganda likes to do.
