Giants
Γίγαντες
The race of giants Gaia bore in revenge after the Titans were imprisoned.
They were said to be born where the blood of Uranus fell to earth — with one condition attached: no god's hand could kill them.
So Olympus called in a mortal, Heracles — only god and human together could win.
The battle is called the Gigantomachy, and the frieze of the Great Altar of Pergamon is its masterpiece in stone.

Commonly confused
Titans and Giants are different races. English blurs "titan" and "giant" together, so they are constantly confused — but in the myths they belong to different generations and fought different enemies.
