After years went by, Nala grew up to be a fine lioness. When Sora, Donald and Goofy first visit their world, they saved her from a bunch of Heartless that were chasing her. She then asked them to help defeat Scar. But after asking advice from Rafiki, they were cut out of the job.
When Nala tells Sora about Simba's existence, Sora tells her that he is well and alive. Together, they go off to find him.
They reunite with Simba at the oasis and go back to the Pride Lands to face his uncle. Simba fights Scar and wins, and becomes the new king of the Pride Lands.
Upon Sora's second visit, Nala has become Simba's wife and is carrying their child.
