Having seen many violent attacks on Jedi, Mar has developed a sense of patience. Rather than just run into a problem head first with his blade at the ready, he will often consider his position in a situation, observe and analyse before acting. Mar would rather teach his fellow Jedi how to combat and effectively dispatch Dark-Siders than run as a Lone Wolf, he would much prefer to lead his fellows into many successful battles. It will inevitably be a long Crusade.

Due to his natural demeanour, his lack of emotion and cold eyes, Mar appears to be consistently judging those around him and those who do not know him would believe that his appearance reflects feelings of disdain towards others.

Since the Invasion of New Tython, Mar has deeply believed that his Force Philosophy is the only true belief system for the Force, Any dark-sider is considered a parasite to the Force as a whole and must be exorcised. Mar would take any Force user and try and turn them to the Light, however were he to sense that they were not "Pure" he would be just as willing to execute them.

People tend to reverently follow Mar Sûl’s lead and look up to him in difficult situations. Whether through inspirational behavior, fear and manipulation, or belief and hope for a better future, they think that Mar Sûl genuinely believes what he does. This is all a clever facade, however, as Mar Sûl is not always as upstanding and respectable as his followers believe. He is no idol, but an opportunist who knows how to manipulate a crowd into bettering his own machinations.

Although more than willing to kill anyone he believes to be evil. Mar is also incredibly aware of the ability to influence the tide of combat through morale - meaning that, should he find a way that he can damage an enemies morale, he will. Thus often resulting in Mar attempting to brutally kill his enemies leaders in-front of their troops. However, in more 'intimate' situations Mar would much rather dispatch of his opponent quickly.

Born with an intractable will and limitless courage, Mar Sûl will stand in the face of insurmountable odds and never retreat. Despite the fact that such acts of heedless bravery are inspiring and will sometimes result in victories worthy of song, just as often they result in his allies getting wounded or killed.
