Sirrus is obsessed with unlocking the secrets of the Force, especially as it relates to the Dark Side. He searches for any and all information, scientific and metaphysical, as it pertains to the Jedi and their esoteric orders. He is more of a sorcerer than a warrior, but even more than that he is a scholar and seeker of knowledge.

Before developing his Force sensitivity, Sirrus was an infamous bounty hunter known across the Outer Rim systems. As a consequence, he has many contacts in the underworld, many of whom respect him for his work and even owe him favors. He also, however, has his fair share of enemies who would like revenge on him for crossing them in the past.

Years delving into the secrets of the Sith and the Force had driven Sirrus to the brink of sanity. He has seen and heard unbelievable things, and encountered even more bizarre theories. He sometimes loses his connection to reality, causing him to shut down or become hostile, making him an untrustworthy and fair-weather ally. Sometimes, however, his madness provides him with strange insights.

Sirrus has tended to work alone through his bounty hunter and Jedi careers. Consequently, he tends to be at his best when working on his own, and at a disadvantage when forced to work with others. He has remained dependent on his old allies and been neglectful of cultivating new friends.

As a bounty hunter, Sirrus was a proficient gunslinger and quick-draw artist. He retains his knowledge of using firearms, but he generally no longer carries a blaster due to his reliance on mind manipulation. Due to his going unarmed, he would have to procure a blaster and be in a situation where he would be dependent on a "crude" weapon.

When it comes to Force combat, Sirrus greatly favors manipulating the minds of others. He specializes in Jedi mind tricks and the creation of illusions to spread insanity in his victims, making them see non-existent threats, hear strange voices, and so on. As a consequence, however, he is at a loss when it comes to straightforward combat, such as with a lightsaber.
