"You're going down, Vortex," Jimmy told the blonde girl standing a few feet away from him.

"I heavily doubt that, Nerdtron," Cindy shot back as she took up a fighting stance.

Jimmy ran forward and jumped towards Cindy. He tried to kick her, but she rolled out of the way. Cindy tried to use that opportunity to hit Jimmy, but he got back to his feet and resumed his stance.

Jimmy dodged the two blows that Cindy sent flying at his face. He smiled as he jumped and spun around in the air, kicking her backwards. Cindy hit the ground and rolled backwards. She did a back flip and landed on her feet.

Jimmy and Cindy closed the gap between them. Both let loose several punches at the other, all of which were blocked. Jimmy grabbed a hold of her wrist and twisted it. Cindy jumped up into the air and rolled in the same direction, sending a kick towards Jimmy's head as she did so.

Jimmy did a backbend as the foot narrowly missed his face. He proceeded to do a backwards somersault, grabbing Cindy's leg with his at the same time. Cindy was surprised and helpless as Jimmy flung her into a wall as he continued moving backwards.

Cindy hit the wall and slid to the ground. The look of concern on Jimmy's face quickly faded as Cindy got back up, this time holding a nunchaku (nunchucks) in her right hand. She grinned as she began spinning it. She moved towards Jimmy and lashed the weapon at his legs, which he dodged by jumping into the air. Cindy swung it at his head, which he managed to avoid by rolling backwards.

Jimmy grabbed a bo (a long wooden staff) off of a rack on his wall and smiled at Cindy. He swung it at her head, which caused her to duck. He then quickly swung it again at her feet, successfully knocking her to the floor. She dropped her nunchaku, which she tried to reach for. Jimmy slammed the end of his bo against the nunchaku's stretched chain. He slid it away from Cindy.

Jimmy put the bo down and helped Cindy up. They both bowed at each other.

"You were amazing!" Cindy told him as they headed to the lounge in his lab.

"You weren't too bad yourself. You're really good with the nunchaku," he told her as he took a seat and turned on the TV.

Cindy grabbed a glass of water and joined him on the couch. "You're amazing with that bo. All of your training is really working. And you learned all of this without a teacher?" Cindy asked incredulously.

"Hey, that's what the internet and instructional videos are for," Jimmy said as he took a sip from Cindy's water.

"John is going to be no match against the two of us," Cindy happily said as she wrapped her arms around Jimmy.

"Yeah, he won't be as lucky as he was last time," Jimmy said as he thought back to the brutal beating John had given him two years before. He fingered the scar on his leg from when he had fallen down the stairs.

"Remember how puny you were back in fifth grade? You had to build those stupid nano-bots to protect you from Butch," she teased him.

"Yeah. Those were the days," he said as he looked off into space, remembering how carefree he had been back then. Now he had the whole world to save.

"So, you up for a movie?" Cindy asked him.

"Yeah, why not. You want to ask the rest of the gang to come? We haven't seen them in days," he lamented.

"Sure, let's just get out of this hot lab and into the air-conditioned movie theater. Why don't you have air-conditioning in here again?" she questioned.

"So sorry. Next time we'll train in your lab," he said sarcastically as he grabbed Cindy's hand and walked out of the lab.
