Kion, the second-born cub of Simba and Nala, discovers that he has the ability to channel the roars of the Great Lions of the Past, giving him fierce power just like his great uncle Scar who had the same power before him, but who tragically misused it for evil and lost it forever. At the instructions of Simba and Rafiki, Kion forms a team called the Lion Guard. As Kion goes against tradition and chooses his non-lion friends Bunga the honey badger, Ono the egret, Beshte the hippopotamus and Fuli the cheetah to populate it, Simba scolds him for not taking his new responsibilities seriously. When they save Kion's sister Kiara from a herd of stampeding gazelle and defeat a hyena clan led by Janja and Mzingo the vulture, Simba realizes that Kion has protected the Pride Lands and is indeed ready to lead his new Lion Guard.
