Hera

Hera is the Queen of the Gods, and the wife of Zeus from Disney's 1997 film Hercules.

Origin
In Greek mythology, Hera was known as the Queen of the Gods, wife and sister of Zeus, the King of the Gods. Hera was the goddess of marriage and women. Hera was Hercules's step-mother and his enemy. When Hercules was born, she sent 2 serpents to kill him, but he was found instead playing with them as if they were toys. She also is involved in the origins of the Milky Way when Zeus tricked her into nursing Hercules and she tore him away from her once she recognized who the baby was, severely wounding her.

Hercules
In the 1997 film Hercules, Hera is portrayed as the mother of Hercules. In actual mythology, Hercules' mother was a mortal woman (Zeus, despite being married, had children with numerous other women), and the jealous Hera acted as an antagonist to Hercules (much like Hades in this version).

In contrast to this, the Disney version portrays Hera as a loving and kind mother to Hercules. She appears to be somewhat overprotective of him, as evidenced when she objects to her Husband Zeus letting the newborn Hercules play with his thunderbolts. She is voiced by Samantha Eggar. Hera does not seem to be as unfriendly to Hades as the other gods in the series, as shown when she persuaded Zeus to attend Hades' pool party.
