Nuka is the secondary antagonist of The Lion King II: Simba's Pride. He is the son of Zira, and the older brother of Kovu and Vitani.
- Thin and lanky
- Takes after his fellow Outsiders in appearance, though he's in worse condition than most. Standing side-by-side with his young adult sister, he isn't much taller than her despite being considerably older.
- With little access to food or water, his body is malnourished, a condition which manifests itself in the slightness of his frame.
- He is dirty and scruffy
- plagued by termites in his teenage years, and generally disheveled in appearance.
- Lack of physical prowess,
- Lithe and strong, able to temporarily restrain a grown Simba despite his young age and keep at the head of the pride with Vitani and Zira when a chase ensues.
- Fur is colored grayish-brown with noticeable tinges of reddish-brown
- Muzzle, paws, and underbelly are all dark brownish-gray in color.
- His mane is dusty black.
- His eyeshades are dark, but he has dark scarlet eyes
- Nuka's mane is thin and very scruffy, reaching past his forelegs but not quite filling out the way those of other lions do.
- Both his mane and his tail tip are ragged, and he bears tufts of fur on the backsides of his elbows and a small beard on his chin.
As an adolescent, Nuka is shown to be an unappreciated bully whose only concern is to be loved and recognized by his mother. Rejection seems to take a heavy toll on the young lion, making him resentful of his brother for being the chosen one and downgrading of his mother behind her back. Perhaps because his accomplishments go unrecognized, Nuka feels the need to be powerful, taking great pleasure in bullying his younger siblings and boasting about his own capabilities to their faces.
Despite his arrogance, Nuka is irresponsible and detached from his siblings, leaving Kovu to brave the Outlands alone despite the cub being Nuka's responsibility. Nuka is also shown to be spastic and easily angered, losing his temper over a simple bout of termite itching. His judgment can understandably be called into question when he grows into a young adult, as he initially accuses Kovu of being a traitor without waiting for his mother's explanation. His inner motive, to gain his mother's appreciation and love, often fogs his common sense.
