When researching more about Wonder Woman depicted in Batman v Superman: Dawn of Justice I found slightly contradictory information about her background in the comics.
On Wiki, it said: Wonder Woman is a warrior princess of the Amazons (which are based on the Amazons of Greek mythology) and is known in her homeland as Princess Diana of Themyscira.
And I just read somewhere: Wonder Woman is the offspring of Zeus and Hippolyta and as such should be at least a demigod.
Which one is true? Or both? If she is the offspring os Zeus, does that make her immortal? What is her background in the DC films released as part of the DC Extended Universe and on what comic origin is it based?
