Kratos risked calling himself Dominus, according to one of the developers who were then part of the Sony Santa Monica development team.
Kratos, the protagonist of the God of War series, risked calling himself Dominus. It was Stig Asmussen, currently at Respawn Entertainment, who told this to IGN, but at the time was engaged with Sony Santa Monica.
According to his words, the name Dominus was used for months to refer to the protagonist of the first God of War, but it soon became clear that the name did not fit the character well. What liked was the assonance with the English verb to dominate, which well expresses a part of the character of Kratos, but the meaning of the word Dominus and the difficulty of tying it to the Spartan’s mission of revenge has made us desist from using it.
The marketing department would have asked for a more appropriate name for the character, given the difficulty of selling the other. It is at this point that someone from the study proposed Kratos. The rest, as they say, is history.
