Simba/ Nala
As cubs, Nala and Simba were best friends and would go on adventures together (including the visit to The Elephant Graveyard). Both cubs were not pleased to learn that they were betrothed to each other, claiming that they could not marry because they were friends. After escaping Zazu, she and Simba argue over whose idea it was and get into a play fight. Nala easily beat Simba after he pounced her by flipping and pinning him, and did so once again when he tried pouncing her a second time, teasing him "pinned ya." While the two were being chased by the hyenas, Nala was nearly kiled by Shenzi, but Simba saved her by scratching Shenzi. Nala, along with the rest of the pride, was devastated when Scar told them that Simba, along with Mufasa, had perished in a wildebeest stampede.
Years later, Nala gets into a fight with a young lion, whom she pins down. The lion recognizes this move and says Nala's name and says that he is Simba, which makes Nala overjoyed that her friend was alive. Eventually, the two friends became lovers, something they thought wouldn't happen when they were cubs. After the two tumble down a hill together, Simba finally pins Nala, and she rewards him with a surprise lick on the cheek and they nuzzle each other lovingly. Nala joins Simba in battling Scar and the hyenas, after learning that Scar was responsible for Mufasa's death and had blamed Simba for it.
