Cú Chulainn is the mythical Hero of Ulster, son of the god Lugh of the Long Arm and Dechtire, daughter of Conor, King of the Ulaids of Northern Ireland, around the 1st century BCE.
A warrior known to transform into an uncontrollable mad berserker during battle, his body would revolve in his skin and his face distort with one eye bulging from his face, screaming battle-cries so loud that people would go insane hearing them.
Taught the martial arts by Scáthach, Warrior Queen of Skye, she gifted him a magical spear called the Gáe Bolga – the belly piercer.
