Zeus's History
Zeus, also known as Jupiter, was the king of the Old Gods, worshipped by the Amazons, ancient Greeks and Roman civilizations. He is the father of numerous children, which include: the fearsome God of War Ares, the Goddess of Hunt Artemis, as well as the heroic demigods Hercules and Wonder Woman.
When all the other gods were killed by Ares, Zeus fought and was able to defeat and grievously injured Ares, leaving him weakened, before he then used the last of his power to create an island called Themyscira where the Amazons could live hidden from humanity and from Ares, dying in the process.
Despite his death, his legacy lives on both through his daughter Diana, also known as Wonder Woman, and through the powers of the wizard Shazam and his champions, the Shazam family, whom are able to harness Zeus' power for their own use.
Ruling the Old Gods
Zeus ruled over Mount Olympus and his kin, the Old Gods, as the most powerful and eventually fathered Artemis and Ares, among other godly and demigodly children.
Creating Humanity
At some point afterward, according to Hippolyta, Zeus proceeded to create humanity, making them in the Old Gods' likeness, imbuing his creation with many virtues.
It was also said that Zeus cruelly punished the Titan Prometheus for enlightening humankind, as Lex Luthor would recall, millennia later. However, the accuracy of said myth is unclear.
As Zeus' son Ares started corrupting humanity with violence, Zeus with the help of the other Old Gods promptly created a new race in response - the Amazons, a species of women blessed with immortality and superhuman attributes, who were intended to protect humanity from Ares' influence by spreading both love and compassion.
Invasion of Earth
3000 years ago , before the modern day, Zeus led a coalition of humans, Amazons, Atlanteans, at least one Green Lantern, and his Old God children Ares and Artemis against the armies of the New God Darkseid. Zeus killed several Apokoliptian Priests and Parademons , blasted back Darkseid himself with more subsequent divine lightning and split apart the nearly synchronized Unity. Following this, the forces of humans, Amazons and Atlanteans divided the three Mother Boxes and kept them contained for millennia.
War of the Gods and death
As Zeus was preparing to lead the Old Gods to the Amazons' defense to free them from enslavement and stop humanity from destroying one another, Ares, who still viewed humanity with envious disgust, violently rebelled, proceeding to kill the Old Gods one by one for disagreeing with his bloodthirsty and extremist ways. Instead of immediately participating in the war, Zeus decided to father a child with Hippolyta as a contingency weapon that could one day save humanity by defeating Ares once and for all, anticipating the possibility that he and the other Old Gods would die in the war. After Hippolyta was impregnated, Zeus fearlessly engaged his malevolent son in combat. Although Ares's powers had greatly enhanced, Zeus was able to defeat the God of War, banishing Ares from Olympus and grievously wounding him and leaving him badly weakened and much smaller, although he sustained severe wounds in the battle. Knowing that Ares would recover and return to create an endless war, which would destroy both mankind and the Amazon races, Zeus chose to sacrifice himself, using the last of his powers to create the protected island paradise Themyscira for the Amazons to live in safety, hidden from Ares and the dangers of the world and Diana would be safe until the time came for her to defeat Ares, an act of power that caused the King of the Gods to die due to his severe wounds made worse due to his overexertion of his powers.
Legacy
Centuries after his death, his legacy lives on within the Rock of Eternity, the source of all magic. The wizard Shazam later bestowed his vast power upon one champion who he found worthy to carry on his mantle and become one of the overseers of the Rock of Eternity. Teth-Adam and the Shazam Family were granted Zeus' powers.
