As a cub, Nala is a bit sassy, spunky, and just as curious, mischievous and ready to get in trouble as Simba is. She is firm about her ideas and beliefs, refusing to let Simba take full credit for her idea to get rid of Zazu.

This carries into her adulthood, where Nala has turned into a sharp-tongued and fearless adult lioness. She fights Simba into submission and isn't afraid to re-inforce to Simba that he is the rightful king no matter how much he denies it, or to tell Scar that they (the lionesses) don't believe he's the rightful king, despite being at a lower rank at the time.

She has been known to press Simba's buttons, blatantly replying, "At least one of us does," to when Simba tells her, "You're starting to sound like my father."
