I would never dreamed that an animation inspired by the legendary El Eternauta would appeared on this community.
While the modern liberals cheers and cherish this work of art, little known from outside Argentina its darkest inspiration and metaphor to the comis itself. Capitalism. Its father, Héctor Oesterheld was a socialist guerilla fighter were kidnapped and murdered during the darkest era of South America, Dirty War, started by the bloody coup in Argentina funded by American liberals and capitalists. Most of HGO family including him were murdered during the resistance against fascism.
Every element and event in El Eternauta refers to the real life's metaphor. Capitalism, colonialism, imperialism, class warfare, socialism and nihilism. HGO concept of "group hero", was from socialism's value of mutual aid. The alien invasion was referred to Argentina's darkest coups in their history during the Dirty War. Another main theme of El Eternauta is class struggle. Class struggle or class warfare, is socialism's oldest principal on capitalism and society.
HGO left El Eternauta as a reminder for the darkness that haunted and took his life. But El Eternauta also serves as an important piece of socialism agitprop to educate people and unite them against one single thing: capitalism. The one thing that killing people, killing you and I silently.
