As Ravager, Zhang will be in the ranks of the Wilson family, who famously provide both friend and foe to the Teen Titans in the pages of DC Comics since 1980. Esai Morales will portray the patriarch, Slade Wilson, aka Deathstroke, frequently billed as the most accomplished assassin in DC mythology and the arch enemy of Titans leader Dick Grayson (Brenton Thwaites). Chella Man was recently cast as Joseph Wilson, aka Jericho, the mute son of Slade and brother of Rose.
The character bio for Ravager: “Daughter of the deadly assassin, Deathstroke, Rose Wilson was forced to undergo the same procedure that granted her father nearly superhuman abilities, becoming a weapon known as Ravager. Ever resentful, she seeks out the Titans not only for their protection but to get back at her father. Knowing how dangerous it is to be the offspring of their deadliest foe, the Titans take her in but that doesn’t necessarily mean they trust her.”
