Lugaid Red-Stripe was a candidate for King of Ireland in the time of Cu Chullain.
According to a story told by Shari, the Stone of Destiny refused to utter the cry that would have confirmed Lugaid's claim to the throne. Cu Chullain, who had supported Lugaid, promptly broke the Stone in half using Gae Bolga. ("Rock & Roll")
Lugaid Red-Stripe was a human male so called due to a stripe of red through his otherwise blond hair.
