It was afternoon. Black Cat was training to get used for her newfound strength in the gym.. She was beating a sandbag for like two hours, without taking a break. And she didn't even feel tired. She was so fast and agile, while her punches and kicks were strong enough to make a foe fall down with one strike.

But that was enough to her. She was in need to try her power against a real challenge. And she knew who would it be. Who could be a better challenge than a pile of muscles?

The Kingpin

In the darkness in the midnight a black figure was swinging among the skyscrapers. Her aim was the longest of them; The Kingpins Tower.

She carefully sneaked into the summit of the building and began to spy inside. There he is!: Kingpin was sitting before his gigantic table, hitting his fingers to each other or making kind of music by hitting them to the table. There was no guards or something but she knew he was a huge challenge by himself alone.

She gave a whistle while she sneaking inside.

''Bored, fatty? What would you say to getting beaten? I guess you will be the best sandbag I've ever used!'' The Feline Felon made fun of him to taunt him.

''Hmm. Guess a little cat lost her way. They say black cat's bring bad luck'' Kingpin said as he stands down and coming before Felicia.

''But what if that bad luck turns to you?'' He charged to Feline Felon but she just stepped aside it. He lost his footing and fell down. Black Cat began to assault him with an unnatural speed and strength. But that was just not enough to made him feel pain.

''Naarggh!'' Kingpin moaned as he got to his feet and swung a punch to Felicia, she again dodged it and hit him from his belly. Kingpin moaned as Felicia kept targeting his belly, like she found a point of weakness. Kingpin yelled in pain and pushed Felicia, which caused her to almost lose her footing but she stood still. He grabbed Felicia with his one hand and throw her to the edge of the room. Felicia shouted a web from her wrist with a survival instinct and pulled herself to the wall at the next edge of the room.

''Ooo, looks like this cat has some spider abilities too. I missed fighting with that tiny spider'' Kingpin laughed. Felicia instinctively caught him with webs and attacked him with punchs and kicks.

Finally, the legendary Crime Leader, the man with unnatural strength fall before her. She immobilized him to the ground and left a note:

''Guess New York missed her Black Cat''

…

''Well now, looks like our dear little cat has something to explain for'' Peter said as he stood before Felicia, his six arms crossed. They were in the house of Peter, Felicia's head bowed.

''I don't know how did you hear it and I don't care.'' Felicia said. ''My destiny is fighting against crime and protect Manhattan. So I thought I need to do something to prove myself to you''

''That's ok. But I followed you last night and saw how you fought against The Kingpin. I know you have athletic abilites since your childhood. But that fight performance wasn't normal and I saw that you shot webs like me.. It was like something you boosted yourself with something you shouldn't meddle. And I need to know what you have done'' Peter asked. There was an anger in his eyes.

''I will confess it if you wont be mad'' Felicia whispered.

''Oh, here comes the bad thing. '' Peter said. 'Go on''

''I've stolen a serum from my Mother's lab. Created with a purpose of giving whoever uses it unnatural strength and agility.''

''WHAT?!'' Peter exclaimed. But he realizes he didn't have to. He always knew his darling loves to do crazy things.

''Well, Guess it wouldn't do any harm. But I personally hate the serum stuff. I hope it won't cause any trouble, my dear'' Peter said.

Author Note: Now this is a short chapter for just showing that serum had instant effects over Felicia.
