Even that one about literal terrorists ends up changing absolutely nothing about society.
One Piece : I gotta post some spoilers to talk about it:::: large plot spoilers The main characters dad is literally based off Che Guevara and is always portrayed as the side of good. His ship is named Granma, same as Che’s. He’s the leader of a force named the revolutionary army. His second in command is named Invankov: queen of the kamabakka kingdom which is an island of gender fluid people who can physically change genders any time they want thanks to Invankovs hormone powers. They go around liberating islands from the world government and freeing slaves.
The main character and his crew embodies freedom and I’d say communist ideals but they never really explicitly say so.
There is an arc where they must dispose of a king who was hoarding doctors for himself. It feels like a metaphor for socializing healthcare.
In most of the arcs after the introductory ones, they team up with natives to force out occupiers who are displacing them, or straight up enslaving them.
One of the first long form arcs they fight what’s basically a world government funded NGO who is trying to coup a king in the Middle East by controlling the resources (water).
They fight the CIA of their world.
There are consistent themes of freeing slaves throughout.
The world government is controlled by disconnected incestuous billionaires that all gave themselves the title of “saint”
There is a villain who is liberal coded, who creates a Disneyfied kingdom using fear.
Another is libertarian coded who occupied a land that he turned into a weapons manufacturing island.
There is an alt right coded villain who also turns the occupied kingdom into a weapons manufacturing island. ::: It’s a big commitment due to length.
I love the absurd art style (aside from every woman looking like the same character and some portrayals I found insensitive or offensive) but a ton of people have a hard time getting past how goofy it looks. Characters can look ridiculous and proportions mean nothing. Humans heights seem to vary between 1ft - 30ft tall.
The absurdist and cartoony nature of it can be off-putting to a lot of people but personally I love it and wish more things were like it.
There are a lot of problematic elements throughout that you’d need to look past and just enjoy the overarching message.
No.6 comes to mind though I recommend reading either the novel or the manga before even glancing at the anime. The author is part of the Japanese Communist Party and though I have some gripes with how the story ended I still think its worth a read. Also yaoi happens
Iron blooded orphans is good
Code Geass never discarded its anticolonialist theming
But it never be anything more than wearing anti-colonialism as a theme though. All the anti-colonialism movements are brain dead backward monarchist and other feudal alliance who got infiltrated by a white savior figure that took over the movement for personal benefits. It even tried to frame Japan as a victim of colonialism and imperialism while having no understanding of how brutal actual colonialism is. Worst of all, at the end of the show it was just two cliques of the world super imperialist power duking it out with nukes to see who’s the world emperor, which the white savior guy decided should be his sister.
The Rose of Versailles. I very much recommend.
