Note: This story takes place in and altered version after the Future Trunks timeline. The character called Neo is 18 years old.

Cell's shock soon turned into a grin. "It looks like we have another challenger. So what's your name?"

"I'm Neo, and I've come to kill you." I know this guy is evil because he's fighting grandfather, and I'm sure that I have more than enough power to defeat him. Neo powered up and became a super saiyan.

"Another super saiyan. Don't make me laugh. If Goku couldn't beat me what makes you think you can?" Cell's smirk soon disappeared when Neo reached his maximum as a super saiyan; he didn't need to go super saiyan 2.

Vegeta was humbled. This…this kid…his power is amazing. He's even stronger than Kakarot!

Future trunks was confused. What is going on here? Who is this guy and where did he come from? And why didn't I know about him?

Piccolo eyed Neo with suspicion, while Tien, Yamcha, and Krillin tensed up. None of them knew if they could trust him, but they all knew that if he wanted them dead, the were as good as dead.

"This can't be happening! How could he be stronger than me? I am perfect!" Cell powered up to his maximum, but found that he was still significantly weaker than Neo.

Goku landed on the rock where everyone else was standing. "Hey Krillin! Can I have a senzue bean?"

"Sure thing Goku!" Krillin threw a senzue bean at Goku. Goku caught the bean and ate it. "Hey Goku…do you think we can trust this guy?"

"I'm not sure Krillin, but this guy seems to be against Cell."

Cell charged at Neo and attempted to land a punch. Neo ducked swiftly and in one smooth motion jabbed Cell in the gut in a style similar to 17 and 18's. Cell bent over as he stepped back. He had a glob of saliva hanging out of the side of his mouth. After he recovered he let out an angry roar and started punching and kicking rapidly. Neo avoided every attack. Neo saw an opening and tripped Cell. When Cell was down he kicked him in the gut, sending him rolling for a few meters. Neo walked over to Cell and picked him up by the neck. He held him with one hand while charging an attack in his other hand, like a kamehameha wave. After choking Cell for five minutes he threw him into the air and let out his attack. "Spark Canon!" Cell was blown to bits, but Neo still sensed his power level. He saw Cell's core attracting all the bits. He took out his sword and sliced the core into tiny pieces. With his core destroyed Cell was no longer able to regenerate. He was dead.

"Am I dreaming? Did he just destroy Cell?" Krillin became nervous when he realized what happened. "Goku, what should we do?"

Goku smiled calmly. "We should thank him for defeating Cell for us. He doesn't seem bad to me."

"Hey Piccolo." Piccolo turned to look at Gohan. "I think I recognize that sword. It looks like the one you gave me to prepare for the saiyans."

"It looks exactly like it. Did you happen to lose it?"

"No, I always keep it in my room is a secret compartment so my mom doesn't find it. I haven't told anyone where it is yet, not even my dad."

Vegeta gritted his teeth and clenched his fists. How could I let this happen? How did I not sense him before? He has done what I should have done. He reminds me of Kakarot. Always surpassing me! I've got to find out who he is. He's definitely a saiyan.

Neo turned to look at the Z-fighters.

It might be a long time before the next chapter is up. Feedback would be helpful.
