It is not a myth that it is dangerous to wake up a sleepwalker because of the possible injury the sleepwalker may inflict upon themselves or the person waking them up.
Hippolyta, queen of the Amazons, is pretty well known as Wonder Woman’s (princess Diana) mother. Diana’s father however, is a bit more complicated. In George Perez’ reboot of Wonder Woman comics in 1987, he followed parts of the 1942 origin story, including Wonder Woman being sculpted by Hippolyta from clay and brought to life by the gods. In Brian Azzarello’s New 52 run beginning in 2011 however, it was revealed that Zeus is Diana’s father, making her a demigod. Greg Rucka however removed that part from her origin in Rebirth (2016). A year later however, James Robinson rewrote the mythos of Zeus being Wonder Woman’s father into her story.
