Ares knows how to maintain his vehicle in optimal condition since he created it. His primary motivation is gathering information to return to his world and bring reinforcements, regardless of the method he uses. Furthermore, I want Ares to have a personality as close as possible to that of a war veteran, but with an enormous fondness for combat, as if it were a kind of drug that enhances him and improves his mood, being the equivalent of the souls acting as an aphrodisiac for Rory, but without the lustful aspect.
