Before Askari was the leader of the first Lion Guard, the Pride Lands in his time were about to be taken over by a group of evil lions that almost destroyed the kingdom. To stop them, the good lions of the Pride Lands formed a powerful force where the worthiest in the kingdom would be chosen to stop them, giving rise to Askari being the leader of the Pride Lands' first Lion Guard.
During one of his many adventures as leader of the first Lion Guard in the Pride Lands, he and his team made a peace pact between the elephants and the lions, believing that both creatures are wise enough to work together in harmony. He also led a group of animals to Mizimu Grove, though for what reason has yet to be told.
Askari was mentioned several times when the Lion Guard and Makini went deep into the lair in order to find the secret of defeating great evil. Askari and his Lion Guard left many hints as to what sort of dangers they would encounter along the way, making sure that only the worthiest of lions would ever find the Chamber of the Lion Guard and, along with it, the secret to defeating great evil.
