Farrelly soon developed his wrestling character by drawing on Celtic mythology. Wanting to move away from limiting Irish stereotypes of lucky charms, leprechauns and alcoholism, he instead wanted to portray an Irish warrior. Going to a Gaelscoil, Farelly grew up aware of the four cycles of Irish mythology and, inspired by the artwork of Jim Fitzpatrick, incorporated the sword and axe-wielding imagery into his gimmick. This included the design of his own pendant, the crossos, which combines the Celtic cross with a Celtic War sword to illustrate his character's "indigenous origins with a hybrid of warrior strength matched with a strong ethical centre."
