When Kion gets separated from the rest of the Lion Guard, he finds himself lost in the Outlands where he meets Jasiri, a friendly female hyena, who rescues him and helps face off against Janja and the other hyenas.

The Lion Guard must choose whether to side with the hyenas or the lions when Jasiri, the good hyena, asks for help.

When Jasiri and two hyena cubs are in danger in the Outlands, the Guard enlists the help of Thurston the Zebra to repel a tsetse fly infestation slowing down their rescue efforts.

Jasiri offers to help the Guard battle Scar by forming a Hyena Resistance in the Outlands.

After Kion and Ono are injured in an attempt to defeat Scar in the battle for the Pride Lands, the Lion Guard must embark on a journey to the Tree of Life to help them regain their strength.

After learning that the Pride Lands are threatened, Kion uses the Roar to help the Lion Guard return home as soon as possible.

When the Lion Guard returns to the Pride Lands, they discover Vitani has formed her own Lion Guard in their absence.
