Lastly, regarding Zola's work on war machines during the Spanish Civil War, it seems like there might be some confusion. Émile Zola was a French writer who passed away in 1902, long before the Spanish Civil War (1936-1939). Therefore, it's unlikely that he created advanced war machines or worked with HYDRA during that time.
