...in the Percy Jackson series? In the Percy Jackson series, the Roman Gods are more disciplined, warlike, and militaristic than their Greek Counterparts. Ares is already a tempered God of War, would he be any worse as the Roman version, Mars. The angry God of War more serious and willing to battle seems would be pretty bad especially if he hates Percy as he already is.On the other hand would he be more strategic and less angry as he is more disciplined and militaristic. I don't know whether he would be better or worse.
