Romulus is a master of fitting in and impersonation. There is scarcely a planet in the galaxy where he can't manage to find a way to fit in, be it throwing together a convincing imitation of local guard or pretending to be a regular local. Romulus is so good at such that he may have seemingly lost all sense of personal style and flair, leaving him as always simply the imitator.

While Romulus will see a job through to its conclusion and put forward his best effort, it’s still just a job. Romulus's true loyalties lie to his friends, and through thick and thin,he will stand by them and die for them if needed. This loyalty is reserved for those who have earned Romulus's trust, putting him at odds with other Mercenaries that are only doing a job for the money. This also makes it harder for employers to trust his motives, often times creating extra competition and difficulty finding work. None of it matters to Romulus, though, because loyalty to his friends is not something credits can buy.

While generally laid back and more than happy to offer a quip of sarcasm, Romulus's entire demeanor changes once combat begins. He becomes focused and quiet, with his smile replaced with a look of grim determination.

Killing has never been a problem for Romulus; and he kind of enjoys it now, if he is honest. Killing's what Romulus does, and he likes what he does.

Where most err on the side of caution in a confrontation, Romulus prefers to charge in head-first. While others may skirt a battlefield or keep their careful distance, Romulus rushes in with devastating attacks with seemingly no regard for safety, relying upon instinct and possibly armor to protect him from dismemberment and death during his all-out attacks. Romulus is a force to be feared on the battlefield, leaving a trail of death and destruction. However, Romulus's blood-hungry ways put him in far more danger than the normal combatant, often resulting in needless injury and suffering, trading safety for pure offensive ability.

Romulus wears out his opponents through use of the Force, agility, and evasion. Once he has sufficiently tired his foes through the Force, physical, or mental assault, he quickly tries to find a means of cleanly and swiftly dispatching them - usually resulting in a somewhat risky all-or-nothing attempt at a deathblow.
