We recently found out that Esai Morales had joined that cast of Titans season 2 as Slade Wilson/Deathstroke, and now DC Universe has officially announced that up-and-comer Chella Man will play Joseph Wilson, aka Jericho.
This take on the DC Comics character is described as being "mute after his father failed to rescue him from having his vocal cords severed by assassins, Jericho has the unique ability to possess anyone just by making eye contact. This gentle natured yet proud hero has proven himself a formidable Titan."
Man, who is "deaf, Genderqueer, Chinese, and Jewish", made a name for himself with his popular YouTube channel and has also done some modelling, but this will be his first major acting role.
Deathstroke's daughter, Ravager, is also expected top be cast. She's been portrayed as both an antagonist and member of The Titans, so there's a decent chance the show will follow suit in that regard.
