I do not own Mega Man X or Dragon Ball Z

Trunks lead the group through the halls of the building to bulma's lab. Zero was impressed by what he saw in the lab, 'This looks like Douglas's shop' He thought. Bulma looked up from her project, "Hey Krillin, what brings you here?" she asked. Krillin scratched the back of his head, "Uh, to tell you the truth I need a favor"
"Depends on the favor"
"Um, well first of all let me tell you what is going on..."
Tuning out the discussion, X walked over to the table and saw what she was working on, a motor that was close to a land chasers engine. X loved his Land chaser; he even knew how to fix it and customized his. He became aware of the conversation as Krillin had finished explanation and Bulma sighed, "For once the problem can't destroy the planet" She said. Zero was confused, "And how many times has this planet faced oblivion?" he asked. Vegeta walked in; "With me alive, everyday" he smirked. Zero looked at the saiyin, "Hmm, yea you got enough power, but I doubt you would" Zero said appraisingly. Vegeta nodded "Why blow up a good home?" Vegeta asked.
"Don't know the reason, but some people do anyway"
Vegeta laughed, "Your OK, for a human"
"I am not human"
Vegeta raised an eyebrow, "Than what are you?"
"A robot"
"Not much better"
Zero laughed "But still better"
"This is true. Do you know how to fight?" Vegeta said with a grin.
"It is my job, but I can't hurt humans"
"Problem solved, I'm not human either"
"Lead the way"
Krillin said a prayer under his breath for Zero. Few have ever come out of the gravity room in one piece; Even Vegeta sometimes had to be carried out. "Well, I hope your friend can take a lot of punishment, He is one of the top five fighters in the universe" Bulma said. X paled, "That's a joke, right? How can he be that strong?" He asked. "Follow them and find out. Just hope that Vegeta doesn't go all out or he is toast" Bulma said. X just nodded and ran down the hall after them. He tried to stop Zero for a second but he was too late, The door shut before he could stop it.
"Ok, listen up Zero. This is a gravity room, this one can go up to 500 times earth's gravity. If you can't handle that much tell me now before I turn it up to full. As for the rule, there are none" Vegeta explained. Zero gave a grin, "I can handle it, But no rules? This ought to be fun" zero said drawing his saber. Vegeta raised an eyebrow, "An energy weapon? Do you have another?" he asked. Zero nodded and tossed one to Vegeta. The saiyin pressed the button and the room became heavy. The two sabers gave off a hum as they were swung through the air. Vegeta was almost too fast for zero, Zero may be able to survive the extreme gravity but he was slowed down. Zero chose to use more 'special' fighting styles. Vegeta was surprised by a flaming sword nearly giving him a hair cut. He retaliated with an energy blast that missed by only an inch. Zero wasn't expecting that. Here was a being throwing around energy, "How did you do that? I thought only reploids could throw energy around like that" Zero said. Vegeta smirked, "I can throw around more than that!" Vegeta said. Zero dashed to the side as Vegeta let loose the massive blast. 'I've got to stay alert or else he'll kill me. That would have vaporized me. Guess I have to step up on the attack' Zero thought. Zero and Vegeta fought for another thirty minutes and both were exhausted. X stared in shock as his friend fought this being who could wipe him off the face of the planet. The girls watched with mixed emotions; Iris watched in horror as Zero fought this. monster as losing, Alia thought it was a great show, and Bulma was bored of watching Vegeta fight. Vegeta stood up straight up, "You have been a worthy opponent my friend, few have ever lasted this long. I'll give you this chance to leave now, or else I'll crush you like a bug" Vegeta said calling forth his Super saiyin powers. Zero could see that Vegeta got stronger and did the one thing he could, he called for his armor and backup, "X, give me a hand here, will ya" Zero yelled. X gulped, his friend needed his help against this "saiyin" thing and he was too scared to help. "Uh, you sure you need my help? You seem to be doing fine on your own" X said. The door to the GR opened, Zero saw someone he did not expect. "You need help?" Iris asked. Vegeta was rolling on the floor with laughter, "You ask your friend for help and all you get is your.mate comes to your rescue, HAHAHAHAHAHAHA" he said while laughing. They say hell hath no fury like a woman scorn, well they never met Iris in a bad mood. Zero blushed and paled at the same time, He paled because Iris was mad. He blushed for the 'mate' comment. "That was the wrong thing to say about me mister" Iris said. That was the last thing Vegeta would hear for the rest of the day.
