Zeus

"Greetings there, young man! Look, your father's always been rather difficult, and he's not so much as called in quite some time. You'll have a better home where you belong, here on Olympus! And to help you on your journey, have my blessing." Zeus is the god of the sky and thunder, and the ruler of the Olympian Gods. He offers boons to Zagreus which give his abilities chain lightning or lightning strikes.

Zeus boons excel at dealing damage to groups of enemies, as chain lightning effects bounce between enemies, and lightning strikes can hit multiple enemies.

His signature Status Curse is Jolted, which causes enemies to inflict damage to themselves when they attack, consuming the Curse.

Zeus is one of four Olympian gods (the other three being Artemis, Demeter and Aphrodite) who will not appear in the very first run of a save.

If given Nectar, Zeus will give you the Thunder Signet.

Zeus' affinity gauge is maxed out at 7 hearts.

History
Knowing his brother had an interest in Persephone and feeling sorry that Hades had gotten stuck with overseeing The Underworld, Zeus kidnapped the daughter of Demeter as a "consolation prize" for his brother. An act his brother had never asked/hinted/wanted him to do. While Persephone was happy for any reason to leave Olympus (a fact Zeus was aware of) & went with him willingly, she notes that even if she didn't want to go, Zeus still would have taken her.

This act led to his & Hades estrangement as apart from his disgust at Persephone being treated as an object, this "gift" put Hades in a difficult position; Demeter would be enraged over her daughter's kidnapping but since Persephone didn't WANT to return to Olympus he couldn't send her back.

As a result, if the olympian gods were to find out the truth, war would break out between Olympian gods, themselves and the Chthonic gods of the underworld. Already at the limit of tolerance for Zeus's selfish antics and since there were numerous other options Zeus could have done to get Hades and Persephone together WITHOUT putting the world in danger, Hades cut Zeus & the rest of Olympus out of his life.

Personality
On the surface Zeus appears gregarious, affable and fatherly especially in contrast to his brusk brother. But while his brother Hades is kind & fair underneath his exterior, Zeus is the opposite; at his core Zeus is a selfish god who does whatever he wants without consideration of the feelings of others or the possible consequences of his actions. Even his acts of "kindness" are rooted in selfishness. If not done for his own self interest, they are based on what HE feels is kind, not what others want and will even realtiate on those who spurn his gifts.

What's more he never accepts responsibility for his actions even seeming incapable of RECOGNIZING that he plays a part in them.

Case in point:

He stole Persephone as a gift for Hades setting up the world for a war among the gods. While Hades had an interest in the daughter of the goddess Demeter, he never asked for his brother's help in getting her attention, much less kidnapping her and he certainly didn't see her as a "gift" that could be given away like an object.

This puts his discussions with Zagreus in a new light as it's clear he can't fathom WHY Hades hasn't contacted him or even that he, Zeus, could have done something to make him mad.

Favor
Zeus' favor involves hearing the other Gods' opinions of him, as well as seeing Zeus express a desire to reconnect with Hades, along with Hades' response.

Mechanics
Zeus boons mostly revolve around two main effects. The first is chain-lightning. Chain-lightning effects will bounce between enemies, dealing damage to each enemy they bounce to. Additionally, Zeus also can grant lightning bolt effects, which cause a lightning bolt to strike an enemy, dealing damage in an area around it. These are both considered "lightning effects" and can be improved or amplified by other Zeus boons, such as Static Discharge, which adds the Jolted effect to all of your lightning effects.
