Two moments from the original Lion King that both involve Sarabi:
Her marching in through the crowd of hyenas when Scar bellows for her with her head held high and a perfect sideye of disdain at the hyena snapping at her.
Then later, after Simba forces Scar to confess to Mufasa's murder, it cuts briefly to a shot of Nala and Sarabi. Nala immediately leaps snarling into the fight, while Sarabi has this look of pure rage before going after her: "You killed my husband, let me think my son was dead, destroyed the pridelands, and messed with my son's head so that he'd run away and I missed him growing up?! I will fucking end you."
