|“||You. Oath-breaker. Do not think I have forgotten.||”|
Styx married the Titan Pallas, with whom she had four children; Zelus (“Zeal”), Nike (“Victory”), Kratos (“Strength”) and Bia (“Force”).Zeus was assembling his allies, Styx and her children traveled to his base, whereupon she immediately swore her allegiance to him. As she was her first ally, Zeus was immensely grateful for this and bestowed high honors upon Styx. He decreed that the name of her river would be the one by which the gods took their solemn oaths, and that her children would live with him and the other gods. memory and forgetfulness, Apollo sees the goddess glaring at him and promises to make him pay for breaking his oath to never fire an arrow or play music until he became a god again.
When Apollo encountered her in his dream, Styx had ebony hair that was wafting in the cold current. Her face appeared delicate and sublime. Her obsidian eyes gleamed with absolute hatred.
Styx's dress billowed around her like volcanic smoke. Her lipstick, eye shadow, and mascara were all expertly done in shades of midnight. In another one of Apollo's dreams, Styx was wearing black silky robes.
According to Apollo, Styx is the strongest child of Oceanus and Tethys, showing some fear of her himself.
- Hydrokinesis: As an Oceanid, Styx possesses a considerable amount of power and control over her river.
- Binder of Oaths: As the river all people, even the gods, swear upon, Styx possesses the power to bind an oath and punish those who break them. However, no Olympian seemed to be directly punished by her, though their demigod children were often punished instead.
- Necromancy: Styx can summon the souls of those who have broken oaths to her aid. Their souls belong to her in death.
- Odikinesis: As the Titaness of Hatred, Styx can sense, insight and remove hated.
- Hypnokinesis: Styx can control and enter to the dreams of others. She was able to speak to and influence the hallucination-like dreams of Apollo.
- Orcus is said to be Styx's ruler in his Roman Self.
