In Greek mythology, Cronus (or Kronos) was a giant

Explanation

He was a Titan, a member of the older generation of gods that preceded the Olympians, and is not described as a giant in the original sources. The actual giants of Greek mythology are the Gigantes, a separate race born from Gaia who fought the Olympians in the Gigantomachy. The image of Titans as giant-sized comes from modern popular culture, and Cronus is also sometimes confused with Chronos, the personification of time, due to their similar names.
