Big Mac (gaelic: Mhor Martbhorgaire) was an Irish warrior, born in Munster, who valiantly fought alongside Brian Boru from 997-1014. While ironically small in stature, Big Mac's battlefield exploits were larger than life and ultimately helped propel Brian Boru into the High Kingship of Ireland. In one renowned Viking raid Mac broke his famed sword "Perseus" but Mac, ever resilient, fought on ultimately beating 47 Vikings to death with the use of a stolen Viking Helmet.
