Black Cat arrived at her penthouse apartment after a stressful night. Tony Stark was moving something from his tower to The Fantastic Four's Headquarters in the Baxter Building, and the underworld had heard about it. So every professional and some unprofessional criminals had gone after it in one major illegal shell game of a theft. One which Felicia had finally won, without anyone noticing... at the moment.
So as soon as she could, she secured the metallic case the prize was in and then open it. Once opened she could see it was six gemstones, perfectly oval stones made of the same unidentifable materials. Which reminded her of tales Spider had told her. Of gemstones with powers over mind, power, soul, reality, time and space. The same colour as the gems before her. Making who ever held any one of them master of the gem's specialty, wielded all together it would make someone a god.
'So if these are those cosmic gems, then I just have to test it...' she could feel the gem's power react to her mind, as she felt more powerful and more intelligence. Which she took as an proof, but she could use a few tests...
Later...
Felicia was enjoying her 'new' apartment. She had used the space, time and reality stones to create her own personal paradise dimension to replace her penthouse. Also gaining ownership of her building and removing her criminal records from legal and law enforcement. It contained art, furniture, and other properties of great value to her tastes. Filling multiple rooms which shouldn't exist in the outside space. Like her tropical beach room or alpine lodge with ski mountains room.
She was sitting in the tropical beach room, in a black bikini and sun hat as well as her black choker with a silver charm... now studded with six small opal gemstones. Red, green, blue, purple, orange and yellow. Infinity gems had turned her choker into the Infinity Choker! But now that she had decked out her lair, she wanted more. She wanted... company.
'Spider, Peter... I didn't realize till he was gone how great he was. Then he wasn't mine, scooped up by Plain Jane. Except now I can do something on it. Of course, this also means I can try out some other strapping men without anyone learning about it. Or women... heck, even with Spider we could share a harem of ladies. Who can distract him if I try our someone like Captain America or Thor.
So how can my fun begin?' she thought as she decided on what to do next.
