Ushari

Ushari (voiced by Christian Slater) was an adult male Egyptian cobra that once lived in the Pride Lands, but moved to the Outlands in Season 2. He is the hidden secondary antagonist of The Lion Guard, a cameo character in The Lion Guard: Return of the Roar, a major character in the first season, and a supporting antagonist in the second season, appearing as the main antagonist of The Lion Guard: The Rise of Scar. He appears as a minor antagonist in Season 3.

Although initially a neutral character, Ushari turned to villainy after being disturbed and injured or run over many times by the Lion Guard, and became one of the three secondary antagonists in Season 2, alongside Janja and Kiburi ahead of Shupavu, Reirei and Mzingo. They were unaware of his treachery until The Scorpion's Sting, where he revealed himself as a member of Scar's army.

In Battle for the Pride Lands, Ushari dies after falling in the lava.
