Because he had asserted himself against the Great King of Hatti, and allied himself with the Great King of Ahhiyawa, his characterization in the Hittite archives is that of "troublemaker", "adventurer", "freebooter", or "mercenary"; from his own point of view he may have considered himself merely to be asserting his own rightful (hereditary?) status. The salience of his exploits in the record, together with his name and claim, render dynastic parameters plausible, but still entirely speculative.
