Graham McTavish, fresh from his appearances in Preacher and Outlander, will play Andrew MacGregor, the leader of the most successful Resistance camp in what used to be the western United States. He’s held the camp together through a combination of discipline and charisma but is forced to adjust his plans once Will and Katie Bowman (Josh Holloway and Sarah Wayne Callies) arrive with vital information that could forever change the Resistance’s outlook.
Wayne Brady, whose genre credits include Syfy's Aftermath, will play Everett Kynes, a highly successful tech entrepreneur who has risen in this new world to become the head of the rebuilt Seattle Colony. Kynes’ technology was used – and misused – by the human collaborators before the Arrival, leaving him with a chip on his shoulder… and a unique relationship with the invaders. Kynes is described as both brilliant and has a messianic belief in his own vision for the future.
Waleed Zuaiter from Netflix's cyberpunk hit Altered Carbon will play Vincent, a moral man who finds himself caught in an impossible position while working for a powerful Resistance group. He will ultimately have to choose between supporting the Bowmans and holding on to old loyalties.
