The Inquisitors are led by the Grand Inquisitor, who used to be a Jedi Knight himself before turning to the dark side. He comes from the Pau'an species, which explains his pale skin, sunken eyes, and jagged teeth and nails.
The Grand Inquisitor in "Rebels" also has a long face, yellow eyes, and red markings on his face. However, in the "Obi-Wan Kenobi" trailer, his appearance is more human-like since his eyes don't seem to glow and his markings are more subtle. Also unlike the animated series, which features Jason Isaacs of the Harry Potter series lending his voice to the Grand Inquisitor, Rupert Friend from the 2021 horror film "Separation" will portray him in the live-action series.
