Extremely late suggestion, but my favorite: Wolf The Quarrelsome. At the Battle of Clontarf, Brian Boru retired to his command tent, much too old (in his 80's) to take part in the battle. As was the custom in those days, a series of champions from each side strode out into the center of the battlefield and met in single combat. Wolf came out from among the knights of Munster, and Brodir, a Viking pirate chief based in Man, represented the Viking / Leinster enemy. Wolf gave him a thorough thrashing, knocking him to the ground and denting his armor. Only Brodir's fast feet saved him from, literally, losing his head. After the battle, Brodir and Wolf met one last time and Brodir's feet couldn't save him that time. Check out the detailed account of Clontarf in the Orkneyinga Saga; it was written by the Vikings from the Hebrides that fought on the Leinster / Viking side. The thing that Wolf The Quarrelsome has over Cuchullain is that he was a real man and a real warrior.

Slainte! Max
