|Portrayed by||Stephen Lang|
Waldo is a former Regent and currently an advisor to the Widow.
Sunny asks Waldo what it is like to escape outside the Badlands, but he tells him that it is full of stories and even though he lets his birds out, they always come back at night. He also reminds him if he tried to escape, Quinn would hunt him down.
Sunny takes M.K. to see Waldo, with whom Sunny trained as a Colt. Sunny orders M.K. to fight Waldo, even though he is bound to his wheelchair. M.K. throws the first punch, but Waldo deflects it and flips him onto his back. M.K. continues to attack, but Waldo uses one hand to block his moves and the other to maneuver his wheelchair. When M.K. surrenders, Waldo warns him not to underestimate his enemy.
Sunny visits Waldo’s shack. Sunny tells him that he is serious about wanting to leave the Badlands. Waldo offers him a toy soldier to offer to the River King, who is the only man capable of getting Sunny out of the Badlands.
Waldo is visited by Ryder, who reminisces about how Waldo saved him from Nomads when he was younger and asks if he’d still have Waldo’s support "if things changed around here." Waldo says he’s "on the side that wins." He says, however, that Ryder should choose his allies with care. Ryder shows M.K.’s pendant to Waldo, who suggests reacquainting with his grandfather to learn more.
Waldo breaks Sunny out of his cell, so he can make it to the River King’s boat and warns him that The Widow is making a move against Quinn and Jacobee. Waldo says he should have saved Sunny "from this life" then passes him a pendant, identical to M.K.’s, he says he found it around Sunny’s neck when he found him. Waldo tells him the ambush is happening at the Dollhouse, but warns him to "be smart" and to forget about M.K.
