Yeah, so this is all covered in that video. Spiderman is probably the closest to progressive listed. He's working class, he has trouble with cops, his family is poor. He's reactionary in the literal sense, because he takes action in response to super villains. He doesn't ever do anything proactively to make the world more just, he just responds to people trying to make it worse. Imagine if he robbed a bank and gave it to the poor or broke in to an ICE vehicle depot and disabled all their vehicles so they couldn't raid immigrants. By the standard construction of the genre, he'd automatically become a villain... And that's the point.

Subversions of the genre aside, It can be no better than liberalism. It's like Obama, being a black president who probably did more than any previous president to address mass incarceration while simultaneously ordering drone strikes against civilians, crushing Standing Rock and Occupy, and presiding over the largest transfer of wealth from the poor to the rich in all the history leading up to it. In a lot of ways Obama was the most progressive US president... But liberalism limits the frame of operation. Just like the genre, the best you can do is virtue signaling without ever really challenging the status quo.

The Overton window for the super hero genre goes from (perhaps slightly left of) center to fascist. No matter how many identity labels or progressive situational elements you add, it's still a genre that's literally reactionary and therefore trends politically reactionary.

Again, this is all covered in the video. If you want to challenge your understanding of the world, great. If not, I'm not really going to keep paraphrasing a video that presents these ideas more effectively than I do.
