I couldn't really decide between Iron Man and Black Widow for Jenny to fight against, so she's going to compete with both.

Avengers Mansion- Training Room

"Well, I can't really decide between Black Widow and Iron Man," said Jenny "How about a sparring match between myself and Black Widow followed by a combat simulation where the one who kills the most simulated opponents wins against Iron Man."

"Very well," said Black Widow, a little surprised at Jenny's choice, but glad that she would have her chance to spar with her. Jenny took up a position on one side of the training room, after acquiring two small energy pistols from the armory. Black Widow was opposite her, using her signature wrist guns. Both sets of weapons had been programmed with non-lethal rounds for training purposes.

"Begin," said Jarvis's computerised voice. Black Widow did not go easy on Jenny, immediately somersaulting and kicking out at Jenny's chest, but Jenny was no longer there, cartwheeling backwards out of Black Widow's reach, she remembered the last time she had done this move, on Messaline. That had been the last time she'd seen the Doctor and Donna. She was jolted back to the present as Black Widow performed a spinning kick to her head. She changed direction mid cartwheel, dodging around Black Widow and crouching into a leg sweep which knocked her to the ground. However, this maneuver caused her to lose her grip on her energy pistols. Black Widow brought her leg around Jenny, knocking her to the ground as she got up. Black Widow aimed her wrist guns at Jenny, and prepared to fire. From her position on the ground, Jenny kicked the guns with one leg and tripped Widow with the other, scrambling to her knees, she got on top of Widow, pinning her in a Deashi Harai judo hold, which pinned her to the ground.

"Round over," said Jarvis.

"Wow," said Clint, summing up what every person in the room bar Jenny was thinking. Jenny stood up and held out her hand to Black Widow. Black Widow took her hand and she helped her up.

"Thank you for the sparring, Jenny," said Natasha "I enjoyed it, although, I wasn't expecting to be beaten."

"It was an honour to spar with you," said Jenny, "Perhaps we should do it again sometime."

"I'd like that," said Natasha, shaking hands with Jenny.

"You ready Tony?" asked Jenny, picking up her energy pistols from the ground. Natasha was panting from the combat, but Jenny didn't even seem out of breath.

"All right, let's do it," said Tony, his helmet visor coming down "Jarvis, start up the marksman program, level 10."

"Starting program, sir," said Jarvis "Would the rest of the Avengers prefer to watch from outside the control room?"

The Avengers filed out. Iron Man looked at Jenny, checking her pistols, getting ready for battle.

"Tony," said a voice. It was Clint "You do realize that you can't keep up with level 10, it's a level even I struggle on."

"Don't worry about it, Cupid," said Iron Man, switching to private comms "I've got it under control."

The simulation started. Iron Man and Jenny were standing on a deserted street. Buildings all around provided many places that snipers could remain hidden. Jenny aimed both her guns at different buildings, covering both since she didn't know which one the enemies were hidden in.

Suddenly, the air around them was filled with laser blasts. Both Jenny and Iron Man had trouble keeping count of each other's score. Iron Man continued to fight, not noticing a robot coming up behind him. Jenny did though, and turned her pistols on the robot, blowing it's head off, but at that point, she had taken her attention away from the enemy she had been shooting at, and would have been hit if Iron Man hadn't flown at her, knocking her to the ground so the beam would pass over them both.

"Back to back?" she asked Iron Man. He nodded. Jenny fired her pistols again and again, defeating countless enemies. She had lost count of how many.

"Test over," said Jarvis, and the street vanished, replaced by the white walls of the training room. On a wall, a single hologram showed the total enemies Iron Man and Jenny had defeated.

"Well done, kid," said Iron Man "I'm proud to count you among the Avengers."

"Thank you," said Jenny

"Go and have a rest," said Jenny "Jarvis will show you to your room."

Jenny left the room, being directed by Jarvis to her room in the mansion.

The rest of the Avengers filed back into the room, Hawkeye staring in disbelief at Jenny's score.

"She was at least on par with you, Natasha," said Clint "I've never seen you beaten in hand to hand combat before, even I can't do it."

"Her style is ruthless," said Steve "She doesn't hold back."

"I'd like to spar with her sometime too," said Black Panther "I think we could all learn something from her."

"She looks like she could match a full team of Avengers and she doesn't even have any powers," remarked Jarvis "I would also recommend any of you to spar with her, there is a lot you could learn from each other."
