Zeus is the God of lighting, God of all Gods and ruler of Olympus. In Greek Mythology, Zeus is the one who defeated Cronus. He is the youngest brother of Hades and Poseidon, and married to Hera. Zeus is described as being cheeky, bossy and overly sensitive, which causes his temper to rise. He cares dearly about his brothers, and although he teases them a lot, he is also a source of reason. Zeus is a member of the 6 Traitors Dynasty. 

Zeus is a cheeky man, not afraid to make remarks and wisecracks at the expense of his brothers. However, he can be very sensitive and ill-tempered or how Hades' describes it "Only Child Syndrome", but he will do anything for the happiness of his brothers. Zeus is a very stubborn man especially when it comes to Hera, and he'll often say and do things to spite her. He can also behave inappropriately with women, grabbing women's rears without permission, which usually results in a punch to his face. He also expresses what is recognized as misogynistic opinions, the prime example being how he treats the possibility of Apollo raping Persephone.
