Makuu makes a brief appearance in this film when Bunga jumps onto his head. Makuu lifts himself out of the water in annoyance and growls at Kion who is following suit.

The Lion Guard
As shown in the teaser clip to the show's first episode The Rise of Makuu, Makuu is seen fighting the leader of the crocodiles whilst being watched on by a crowd of animals including Kion, Bunga, Beshte, Fuli, Kiara, Simba, Nala, Tiifu and Zuri. He wins the battle and becomes the new leader of the crocodiles whilst the former leader leaves (as in tradition if the leader is defeated, they are banished from the group).
