Balor

In Irish mythology, Balor or Balar was a leader of the Fomorians, a group of malevolent supernatural beings, and considered the most formidable. He is often described as a giant with a large eye that wreaks destruction when opened. Balor takes part in the Battle of Mag Tuired, and is primarily known from the tale in which he is killed by his grandson Lugh of the Tuatha Dé Danann, son of Cian. He has been interpreted as a personification of the scorching sun, and has also been likened to figures from other mythologies, such as the Welsh Ysbaddaden and the Greek Cyclops.
