Eurosceptic politician and commentator Daniel Hannan, writing in 2011, criticised the "Captain Euro" literature as possibly "sinister". He described the Dr. D. Vider character as having "a hooked nose and a goatee beard, like some anti-Semitic caricature from the "Völkischer Beobachter"", and stated that D. Vider's real first name, David, and his occupation in finance could also be considered indicators that the villain is meant to be Jewish. Hannan also criticised the general concept of using comic-book characters to promote the EU, writing, "The notion that the government should get at parents through their children is a characteristic of authoritarian states, not liberal democracies."
