Fan CastingWhite Tiger: The Disney+ Series

Description of Ava Ayala:

Hector’s youngest sibling & Angela’s aunt, Ava is still in high school in the beginning of the series, unaware that her brother was the superhero she looked up to when she was growing up. She learns that her niece, who yes is older than her, has taken up the mantle & becomes her biggest supporter and often fantasizes about Angela passing on the mantle to her. (Does get ahold of the Amulets off-and-on, albeit always temporarily, & becomes White Tiger that way, but inevitably gets her own set of Amulets toward the end of the series.)
