Introduced as a supervillain opposing Captain America, Falcon, Power Man, Iron Fist, and Black Panther, she is later reformed, becoming the superhero Nighthawk and joining the Avengers in 2017.

Gabrielle Dennis portrayed Tilda Johnson in the second season of the Marvel Cinematic Universe (MCU) / Netflix series Luke Cage.

Tilda Johnson first appeared in Captain America and the Falcon #164 (August 1973), created by Steve Englehart and Alan Lee Weiss.

She received assistance from the Yellow Claw in developing a way to change normal humans so that they became compliant creatures similar to werewolves, and attempted to transform convicts into a werewolf army, but Captain America and S.H.I.E.L.D.

After she pointed out a mistake by one of the doctors, she was fired immediately and contemplated suicide, until MODOK contacted her and hired her for the heist.

The three of them were the only villains to remain loyal to MODOK and get their cash (with a bonus); they appear to be sticking together, and she has offered to help Puma with his legal defense.

[12] During the Shadowland storyline, Nightshade organized Flashmob, a group of former Luke Cage enemies, in order to take on the new Power Man, Victor Alvarez.

[14] A reformed Nightshade later allies with the Nighthawk of Earth-31916, helping him defend Chicago from a group of white nationalists called the True Patriots, and the Revelator.

[15] Sometime later, they help Hawkeye and Red Wolf after they find barrels of epidurium, a synthetic skin used to build Life-Model Decoys, on a truck that was hijacked.

Hawkeye calls Wheels Wolinski to help fix the van until it is revealed that some of the residents are Skrulls, who are being hunted down by mysterious men.

Nightshade apparently secretes chemical pheromones from her body that affect the will of certain animals, including werewolves, making them obedient to her commands.

[20] Logan Lewis is younger Tilda Johnson's cousin, who followed her legacy by adopting Nightshade codename for heroism.
