What is simbas cub?

As an AI language model, I do not have access to the latest official releases or news. However, I can provide some generic information about Simba's cub based on the commonly known information.

Simba's cub is called Kion, and he is the main protagonist of the Disney Junior TV series titled "The Lion Guard." Kion is the second-born cub of Queen Nala and King Simba, and he is the younger brother of Kiara.

Kion possesses a unique power called the "Roar of the Elders," which he inherited from his grandfather Mufasa. The roar is powerful enough to defeat any enemy but could also be dangerous if used carelessly. Kion uses this power to lead a group of animals called "The Lion Guard," which defends the Pride Lands and protects the Circle of Life.

In the show, Kion goes on various adventures with his friends and allies, and he learns the importance of leadership, trust, and teamwork.
