Revolutionary heroes ranging from John Brown to Kim Il-Sung are isekai'd to a fantasy world that parodies shows like 'the rising of the shield hero' to break the chains of slavery in all forms once more and liberate the fantasy workers and the peasants from the yoke of feudal oppression while hunting down so-called "heroes" summoned by the feudal lords who intend to use them as tools to preserve their power and the economic base of their feudalistic slave economy.
I've wanted to make a comic like this (though without any specific historical figure, I think an everyman protagonist would work better for reaching libs) but I've never quite managed to write a version that felt right.
