Kori Ong was a male human who was native to a planet covered in swamps. Sometime between the years of 32 ABY and 34 ABY, the droid BB-8 and the pilot Poe Dameron crossed paths with them while they were participating in "The Walkabout," a rite of passage for their tribe. In order to get them off the planet, Ong assisted them in battling a native humanoid species and locating Dameron's starship. Dameron inspired Ong to pursue their aspirations of journeying through the galaxy during their time spent together.
Kori Ong, a male human from a tribe, was native to a planet characterized by its swamps. Ong was put through "The Walkabout" by their tribe between 32 ABY and 34 ABY, a rite of passage that involved living alone in a swamp on the planet for a certain time period. During this rite, Ong rescued pilot Poe Dameron from the Resistance and his droid BB-8 when they were under attack by a swamp creature. The creature ran away after Ong kicked it and threw a rock at it, and the boy warned it not to return. Ong then stated that they had previously witnessed the creature eat and that Dameron and BB-8 were fortunate to have survived the encounter. The boy saw that BB-8 had sustained damage and made an effort to fix him.

Dameron, who the creature had previously knocked out, came to and expressed gratitude to Ong for saving him. Ong welcomed them to stay the night in their tent, where they told Dameron and BB-8 about "The Walkabout" and their ambition to discover the stars. Dameron said he was certain Ong would accomplish their objective. Ong, Dameron, and BB-8 started looking for Dameron's starship, the Black One, which Dameron had previously used to land on the planet, the following day. They were caught in a net by a humanoid species that was native to the world as they were walking. BB-8 used his torch to set the net on fire and free them. Ong scaled a tree and threw rocks at the natives. Dameron joined the battle, and the locals, terrified by Dameron's blaster, ran away. Dameron complimented Ong's bravery after they arrived at the starship and presented them with a pin bearing the Resistance insignia. Dameron also said that Ong might one day join it, which thrilled the boy. Ong waved goodbye as Dameron and BB-8 departed the planet.
Ong possessed light skin, brown hair, and brown eyes. Ong was eager to fix BB-8 after he was hurt, and they later offered Dameron and the droid their assistance. Despite having the option to return to their village, Ong intended to travel the galaxy and eventually return to support their tribe.
Ong had the ability to climb trees and leap from them. They also succeeded in subduing a creature bigger than themselves by employing a weapon that launched rocks. They fought and defeated numerous members of a native species with Dameron's assistance.
Kori Ong made an appearance in the comic story "An Unlikely Friendship," which was released on October 31, 2018, in the fifteenth issue of the Star Wars Adventures comic book series. James Gilarte wrote the comic story, and Alain Mauricet drew it.
