The Book of Enoch is the source of the fallen angels rebelling and fighting against the angels of God story, and the source of the modern Luciferian Legend.
The book of Enoch is non canonical in either Hebrew or Christian literature is apocryphal, but was cited in the book of Hebrews and in the Epistle of St. Jude so it was known to early Christian communities.
Summary:
The name of the leader of the fallen angles is Samyaza, later changed to Samael, (Not Lucifer). Another rebellious Angel Azazel taught warcraft, weaponry, war, and sorcery to humans. The reason for their rebellion was to fornicate with hot earth women. They had babies called the Nephilim who were Giants. God destroyed them and cast them into a lake of fire and pit of darkness, and killed all of their offspring in the Noachian flood.

This story was later confabulated into the story of the Fall of Lucifer
https://en.wikipedia.org/wiki/Lucifer
But it's best known from is from the Theogony the war between the Olympian Gods led by usurper Zeus against his father Cronus.
https://en.wikipedia.org/wiki/Titan_(mythology)
"Greeks of the classical age knew several poems about the war between the Olympians and Titans. The dominant one, and the only one that has survived, was in the Theogony attributed to Hesiod....The classical Greek myths of the Titanomachy fall into a class of similar myths throughout Europe and the Near East concerning a war in heaven, where one generation or group of gods largely opposes the dominant one. Sometimes the elders are supplanted, and sometimes the rebels lose and are either cast out of power entirely or incorporated into the pantheon. Other examples might include the wars of the Æsir with the Vanir in Scandinavian mythology, the Babylonian epic Enuma Elish, the Hittite "Kingship in Heaven" narrative, the obscure generational conflict in Ugaritic fragments, Virabhadra's conquest of the early Vedic Gods, and the rebellion of Lucifer in Christianity. The Titanomachy lasted for ten years.[2] The Titans were imprisoned in Tartarus after the war had ended. Tartarus is said to be the deepest part of the Underworld and the place where the evilest beings are tortured for all eternity. "

"youngest child Zeus, by tricking Cronus into swallowing a rock wrapped in a blanket instead. Rhea brought Zeus to a cave in Crete, where he was raised by Amalthea. Upon reaching adulthood, he masqueraded as Cronus' cupbearer. Once Zeus had been established as a servant of Cronus, Metis gave him a mixture of mustard and wine which would cause Cronus to vomit up his swallowed children. After freeing his siblings, Zeus led them in rebellion against the Titans."
This story is literally the clash of the titans, with an alternate ending where the rebels win in the Titanomachy, but lose in the book of Enoch.
