Origin and youth
The demigod Sétanta was born in Mag Muirthelne (modern-day County Louth, Ireland) to Lugh, Celtic god of the sun, and to the mortal druidess Deichtine, the sister of Conchobar mac Nessa, King of Ulster.
During his youth, he lived at Emain Macha (modern-day Armagh, Northern Ireland), where his uncle reigned as king, with Súaltam as step-father. He trained in combat with the Craeb Ruad knights of Emain Macha, and by Scathach, the warrior goddess. He was also tutored by mortal nobles and poets.
At age seven, he killed the hound of the royal smith, Culann, and offered himself as guard in the hound's place until a new one could be trained. That earned him the name Cúchulain ("the Hound of Culann").
Adulthoode
An adult, he became Ulster's guardian and champion, and was notorious for succumbing to the "riastrad", superhuman bouts of battle frenzy. As a great power in Celtic tradition, Cuchulain was under a sacred geis, a taboo. Cuchulain's geis, as the Hound, was to eat of his namesake. At some point, he married Emer.
Queen Medb of Connacht and Prince Lugaid of Munster, both from rival kingdoms, conspired against him, leading him to his death: Cuchulain saw the Washer-woman at the Ford, an apparition haunting the great powers of Ireland in those days, portent of unavoidable death. After it, he ate of a roasted dog, thus breaking his taboo and loosing his powers. Within hours, Lewey, King of Munster, disembowled him with a stroke of his spear.
Godhood
Upon his death, Cúchulain was apotheosized to godhood, and inherited his father's spear, which he called "Slaughter".
Modern Age
Chulain remained in Otherworld, with his spear.
When the Warriors Three inadvertently killed the shapeshifting Giant Holth, his father King Gnives demanded as retribution a list of items (all extremely difficult to acquire), including Slaughter.
Knowing the arrival of the Asgardians, accompanied by Thor, the Leprechaun Froud, and came in league with Chulain in order to steal Mjolnir from them.
As they arrived to Otherworld via a sidhe, a fairy mound in Ireland. There, they were welcomed by Froud who asked them to tell a story to a child that they had stolen (in fact Chulain in disguise) in exchange for the borrowing of the Spear. As the Asgardians decided to return the child and steal the Spear. Arriving back to Ireland, Chulain revealed his true form, swiftly beheaded Volstagg and mortally wounded Thor, before being defeated and forced to fall back by Hogun, who intercepted Slaughter. His victims were quickly resurrected using the healing properties of an Apple of Idunn previously acquired by the group.
When Hercules assembled the Gods of War to battle the new gods of the Uprising Storm, Tiresias proposed Cú Chulainn, but Hercules considered him to blood-thirsty, before recalling he couldn't be too picky. It is unknown if he did try to contact him in the end.
