Just to name a few important ones:
Powerful, sneaky, and flirtatious.

Powerful - He is the king of the Greek gods making him powerful.
There are some downside characteristics, however. He is sneaky and flirtatious, which are two different things.
Sneaky - Take the Illiad for example, he cheated the "game" and constantly helped the Trojans. He is always finding a loophole in the game of life.
Flirtatious - Although married to Hera, Zeus often goes around flirting with not only other gods, but mortals and nymphs. Just to name a few:
-Aphrodite, a goddess
-Io, a nymph
-Danae, a mortal
