Fergus mac Róich
Bricriu followed Fergus mac Róich into exile in Connacht following the Deirdre affair. While he was a guest at Cruachan he caused a lot of trouble for Fergus and another lover of his, Flidais, which culminated at the "Táin Bó Flidhais". In the "Echtra Nerai", Bricriu mocks the singing of Fergus, comparing it to a bull-calf's bellowing. Fergus strikes him with 5 "fidchell" pieces, injuring him severely. Later, Bricriu recovered but died at Cruachan at the end of the "Táin Bó Cuailnge" (Cattle Raid of Cooley), trampled to death by the two bulls as they fought.
