Lie is such an ugly word. I prefer "misdirection".
~ Black Cat after Spider-Man realizes she's been lying and using him all along.
Felicia Hardy, better known as Black Cat, is a major antagonist in the 2018 video game Marvel's Spider-Man and a mentioned antagonist in its 2020 spin-off Marvel's Spider-Man: Miles Morales. She is a professional thief and cat burglar who operates in New York City and a recurring enemy of Spider-Man. This incarnation is also noticeably more villainous than her comic counterpart.
She is unseen in the base game, but makes a voice-over appearance, and makes her first full appearance in the DLC episode trilogy titled The City that Never Sleeps as the secondary antagonist, appearing as the central antagonist of Episode 1: The Heist, as an unseen antagonist in Episode 2: Turf Wars and as a minor yet pivotal anti-villainess in Episode 3: Silver Lining.
She is voiced by Erica Lindbeck, who also voiced Loona and Millie (for the pilot episode) of Helluva Boss, as well as Sumire Kakei on the English version of Boruto: Naruto Next Generations, and Jericho in Seven Deadly Sins.
Black Cat is the daughter of and successor to, a professional cat burglar and thief named Walter Hardy. She followed in his footsteps (against his wishes), as a professional thief and career criminal. During her time stealing, she crossed paths with the superhero Spider-Man and became enamored with him. The attraction was mutual, and for a while Black Cat tried to go straight under Spider-Man's guidance.
But despite Spider-Man's earnest attempts to change her, Black Cat could not fully overcome her addiction to stealing and backslid into her old ways, which ended their relationship. Afterwards, Black Cat left New York City behind and the police acquired her gear (though they were not able to identify her as the criminal they were seeking).
Later, Felicia Hardy returned to New York City, leaving clues around New York City for Spider-Man to find to trick him into thinking she was planning to rob many high-profile targets. In fact, the whole thing was a diversion so that she could steal back her Black Cat costume and gear from police lock-up. When Spider-Man brought all of her cat dolls that she had left at the scenes of her would-be crimes to the NYPD, they created a mass EMP discharge that knocked out security and allowed Felicia to make off with her costume and gear. In "gratitude" for Spider-Man playing his part in her manipulations, Felicia left him a present in the form of a new black and red costume.
Later, after the crisis with the Sinister Six, Black Cat returned ostensibly working for Hammerhead. She was assigned the task of stealing important data drives belonging to each of the main Maggia crime families. When Spider-Man confronted her, Black Cat claimed that she was only working for Hammerhead because he had kidnapped her son and was using him as levrage against her. In reality, this was a lie said by her to manipulate Spider-Man into helping her pull off a heist that was too big for her to pull off on her own. Under the false assumption that Black Cat was being strong-armed, Spider-Man inadvertently helped Black Cat steal the rest of the data drives. Unbeknownst to anyone, Black Cat had been giving Hammerhead fake data drives all along, having been manipulating him and Spider-Man, and planning to keep all of the data drives (and the fortune they granted access to), for herself.
Eventually, Spider-Man realized that Black Cat had been lying to him and using him all along, but nevertheless tried to save her when he realized that Hammerhead had put a tracker on the data-drives she'd stolen and was following her. Unfortunately, Spider-Man was too late to stop Black Cat from returning to her penthouse, which Hammerhead's men had planted a bomb at. The penthouse thus exploded as Black Cat went in through the door, seemingly killing her, though her body was not found.
As it turned out though, Black Cat survived, and laid low for a time (likely to keep Hammerhead from trying again to kill her). She later revealed herself to Spider-Man when she saved him from death at the hands of the now cyborg Hammerhead. She apologized for earlier deceiving him, and gave him a hard-drive containing information on Hammerhead before departing again, noting that now "they were even".
Marvel's Spider-Man: Miles Morales
More than a year after the defeat of Doctor Octopus and the Sinister six, Black Cat is nowhere to be seen or heard from during Tinkerer's campaign against Simon Krieger. In this time, Miles Morales, Peter Parker's superhero apprentice has taken over his role as the sole Spider-Man in New York City while Peter goes to Symkaria with Mary Jane.
Black Cat is mentioned in the database of the Roxxon Energy Corporation, which reveals that she worked for them as a contract agent, and was mentioned in a voice memo as one of the potential villains Krieger wanted to recruit to stop Spider-Man from ruining his plans to destroy Harlem. However, Krieger didn't hire Black Cat due to her redemption (which was sometime between after The City that Never Sleeps and before the spin-off itself), leading him to hire Prowler instead.
