Baylan Skoll (Ray Stevenson) and Shin Hati (Ivanna Sakhno)
A former Jedi who somehow survived Order 66, Baylan Skoll lost his faith in the Force and became a mercenary. He now works alongside Thrawn and is shown dueling with Ahsoka. Sadly, this will be one of the final roles of Ray Stevenson, who suddenly died in May.
Shin Hati is Skoll's apprentice, shown invading the bridge of a ship and, like him, wields an orange lightsaber. Her origins are currently unknown.
On top of all that, Hayden Christensen will appear, although it's unsure whether it's as Anakin or Vader in flashbacks.
With all these and some new characters as well, Ahsoka is set to rock the Star Wars universe and be a great ride.
Ahsoka debuts August 23 on Disney+.
