Crystal Yu is a British-Chinese actor and voice artist now appearing as Lady Beifong in Netflix’s Avatar: The Last Airbender Season 2 – bringing grace, gravity and a little seismic menace to the Earth Kingdom’s most formidable matriarch.
She’s also the voice of Alter, the dimension-hopping chaos agent in Apex Legends. Introduced in Season 21, Alter is a void-wielding Legend with a mysterious past – a thrilling fit for Crystal, whose performances are laced with precision, wit, and danger.
On screen, she’s commanded the high seas as the legendary Pirate Queen Madam Ching in Doctor Who: Legends of the Sea Devils, played the fierce but lovable Dr. Lily Chao in BBC’s long-running Casualty (a firm UK fan favourite), and appeared in beloved universes including Good Omens and The Sandman.
Her game credits span realms both grounded and surreal – from Li Tian Ning, the “Sky Goddess” and military strategist in Skull and Bones, to Mercurial, a razor-sharp speedster hero in Capes. In Duet Night Abyss, she voices Fushu, a gentle, self-sacrificing healer from Hauxu – about as far from Alter’s chaos as a voice can get, and proof Crystal’s range runs from void-cracking menace to quiet tenderness. She’s also lent her voice to Diablo IV, with a few exciting new titles still under wraps.
With Avatar now live and Alter still causing trouble, Crystal is stepping fully into the spotlight of the convention world, ready to connect with fans, share stories, and bring a touch of chaos with her. (Earth-bending and portals not guaranteed.)
