What ethnicity was Zeus?

I'm curious, could you elaborate on the ethnicity of the mythological figure Zeus? Given that he originates from ancient Greek mythology, would it be accurate to say that he represents a specific ethnicity within that cultural context? Or is his identity transcendent of such labels, as he is often depicted as a pan-Hellenic deity? I'm genuinely interested in understanding how his ethnicity, or the lack of it, is portrayed and perceived in the realm of mythology and folklore.
