The Ozrelanso represented a sentient species located within the confines of the galaxy. A defining characteristic of the males of this species was the presence of lekku, which were growths situated on the sides of their heads.
In the era known as the High Republic Era, an Ozrelanso named Ratko took on the role of a bodyguard for Tia Toon, a Senator hailing from Sullustan. Ratko's imposing physical stature made his true occupation quite apparent, even though Senator Toon insisted that Ratko was simply her secretary.
Leading up to the destruction of Kijimi, during the time of the First Order-Resistance War, Plesko Marno, who had previously worked as a clerk for the Bureau of Ships and Services, made an appearance at the Spice Runners' Den.
