Jorko was a Myykian youngling of the male variety. He resided on At Attin with his family – his father, mother, brother Neel, sister Tuloo, and his twin brother, Jobo during the time of the New Republic Era.
During the New Republic Era, Jorko, a male Myykian youngling, made his home on At Attin. Living there with him was his family, which included his mother Nooma, his father Nol, an older brother named Neel, a younger sister named Tuloo, and his twin brother named Jobo.
Prior to 9 ABY, Jorko once pilfered Neel's protractor. This led to Neel pursuing him throughout their dwelling, culminating in Jorko leaping onto Neel's head. This caused Neel to collide with the credenza, resulting in a trunk sprain. During 9 ABY, after Neel missed his Career Assessment Test, a human named Wim visited Jorko's home in search of Neel. At the time, Jorko, Jobo, and Tuloo were enjoying a hologram of a circus performance.
Jorko's physical characteristics included blue skin, black eyes, and hair of a blue hue.
Jorko's initial appearance was in "This Could Be a Real Adventure," the premiere episode of the 2024 series Star Wars: Skeleton Crew. The subtitles in English on Disney+ indicated the spelling of the character's name as "Jorko." However, his entry on the StarWars.com Databank initially displayed the name as "Jorka," but was later corrected to "Jorko" to align with the subtitles.
