Summary Now that The Acolyte episode 5 is streaming on Disney +, several questions about the show's new Sith Lord have been answered. This has only brought an entirely new set of questions to mind, all the while offering little clues that could help to reveal more about this character known as The Stranger. One major reveal over the course of the episode is that the man behind the mask was no other than Qimir himself, pulling the strings on the training of Mae Aniseya from both near and far.
Though based on Sol's reaction, this seems to be true, The Stranger knows exactly what he is doing by pitting the girls against the Jedi. He goes a step further at the end of the episode when finding an unconscious Osha lying in the grass, covering her up in an act that could be construed as caring. It is possible that as the series continues, Osha could become his new Acolyte, and it would entirely be due to The Stranger's powerful manipulation tactics.
It is a unique style, as it involves turning one's lightsaber on and off during combat in an effort to confuse an opponent. He then creates a unique poison using bunta, a plant native to Mae and Osha's home planet of Brendok. This poison is capable of killing Master Torbin in a matter of moments in what looks to be a quick and possibly even painless death. By showing he is capable of creating such strong poisons, The Stranger has proven that his abilities far exceed what the Force can offer him.
However, it seems that in the event of an attack from a Sith Lord, her stun weapon isn't much use either. After directly hitting him with a stun blast, he isn't even fazed. He shrugs it off and continues to pursue her and the Jedi as if nothing had happened, showing either that his armor is capable of even more than deactivating lightsabers, or he is so physically strong that he is immune to stun weapons.
This ability is actually shown in episode 3, when Mother Aniseya uses the Force to possess Master Torbin. This is likely because he is masking his presence from them. Darth Sidious did the same thing when he posed as Chancellor Palpatine, manipulating those around him into thinking that he was in the Senate for the greater good. It was this ability that allowed him to reveal himself at the right time in Star Wars: Episode III - Revenge of the Sith, and it was this ability that allowed The Stranger to hide from the Jedi as Qimir.
