Ulster's greatest champion, son of the god Lugh, whose single-handed defense of his province against Queen Medb's army is the centerpiece of the Táin Bó Cúailnge.
Born Setanta, he earned his adult name as a boy after killing the ferocious guard-hound of the smith Culann in self-defense, then offering to take the hound's place and guard duty himself until a replacement could be raised; Cú Chulainn means "Culann's Hound." As a child he also displayed the ríastrad, a battle-frenzy that twisted his body into a monstrous shape and made him unrecognizable and unstoppable in combat.
The Cattle Raid of Cooley
The Táin Bó Cúailnge tells how Queen Medb of Connacht invaded Ulster to seize the Brown Bull of Cooley, timing her attack for a period when Ulster's warriors lay disabled by a curse. Cú Chulainn, immune to the curse because of his youth, held the invading army back almost single-handedly at a series of river fords, invoking his right under Irish custom to fight the army's champions one at a time rather than face them all at once.
The Death of Ferdiad
The Táin's most sorrowful episode has Medb send Ferdiad, Cú Chulainn's foster-brother and closest friend from their shared training under the warrior-woman Scathach, to fight him at the ford. The two duel for days, exchanging gifts and grief each night before resuming combat each morning, until Cú Chulainn is finally forced to kill him with the barbed spear Gae Bulg, a victory he mourns as a tragedy rather than celebrates.
Mortal parent: Deichtine, sister of King Conchobar of Ulster
Conceived when the god Lugh visited Deichtine; some versions of his birth story also name Conchobar's family as fostering him.
