The recurring character, who will be introduced in the Oct. 10 premiere, “will ally herself with anybody — and employ any tactic — to further her own mysterious agenda,” read the initial casting breakdown. “An emotional chameleon, she can flip from stone-cold to flirtatious as it suits her needs. But the loneliness of her singular quest has taken its toll on her humanity, and she finds herself increasingly lost when it comes to genuine human connection.”

Fonda had a supporting role in 2011’s Real Steel. She also had bit parts on Nikita and How I Met Your Mother.
