She is a lioness cub who is part of the Pridelander pride led by King Simba and Queen Nala. She along with Tiifu, serves as a friend of Simba and Nala's daughter Kiara.
Zuri is as sassy, easily upset, melodramatic, and sensitive, despite being a predator, she doesn't like to hunt, preferring others to hunt for her. She has a considerably poor memory. Zuri has also displayed a complimentary and appreciative side after being saved by Kion. However, she also was snobby and ungrateful when, in an alternate ending of the comic, "The Day of the Crocodiles", Kion saved her but got mud all over her fur.
Zuri first appears when she gets her claws stuck in a log (as she was sharpening them, which she did to every tree she passed to keep them shiny), but is freed by Timon and Pumbaa, but ends up being knocked off the log by Bunga (which results in Zuri wounding her paw and breaking a claw) and uncovers a lair of bugs, to the delight of Timon and Pumbaa. Zuri is grossed out by the bugs but is comforted by Kiara and Tiifu. She along with Kiara, Tiifu, Kion, Timon and Pumbaa dance to Bunga's song "Zuka Zama". Afterward, Kiara sends Zuri back to Pride Rock to rest up.
Zuri and Tiifu acted as Kiara's "advisers" during her temporary queenship forcing others to acknowledge Kiara as Queen. They later fail on the job when they let Kiara go to a meeting with Janja by herself.
Zuri along with Tiifu joins Kiara in being trained how to track by Nala. Unlike the others, Zuri is uninterested in hunting (which she considers overrated) and when Tiifu becomes jealous of Fuli hunting next Kiara, Zuri replies that they should let Fuli hunt for them.
After the training is over, Zuri leaves with Nala, Kiara, and Tiifu.
Zuri and Tiifu try to make Kiara look her best for the Royal Buffalo Wallow, which she is to open on Simba and Nala's behalf. However, the trio end up stranded on a island when a flood strikes the Pride Lands. With the help of the Lion Guard, the trio get off the island and go to the wallow.
Zuri is the third lioness in The Lion King films to have blue eyes. The first being Nala (though her eyes are green/blue in the first, blue in the second film and green in the third film) and the second is Vitani.
The parents of Zuri and Tiifu have yet to be revealed, on account of Simba and Nala being the only adult Pridelander lions shown so far in the The Lion Guard. It can be assumed that Zuri and Tiifu's fathers are either rogues or leaders of their own prides elsewhere and that two unnamed adult Pridelander lionesses are Zuri and Tiifu's mothers.
