Titans were first creations among the god in greek mythology. They were birthed by Mother Earth Gaia and was able to devour the myriads of living creatures. They also had the power to dominate the sky and land.
Titan was a race of beings, and they came in different forms and sizes. There were the thousand-eyed titan, hundred-arms titan, dragon-winged titans...
Each of them would have different abilities, but they were all extremely powerful. In greek mythology, they were the strongest rivals to gods of Mountain Olympus. Countless divine wars have been fought, but the gods had no way to eradicate them completely.
Because, they were the descendants of Mother Earth Gaia, as long as Gaia didn't die, they would be the favorite of heavens and earth, blessed by fortune and luck.
