Cell is absorbing people all over Tokyo and has finally reached his second form, causing fear all over the planet. In the search for 18 Cell runs into some plumbers.
"Who are you?" Asked Cell with a grin.
"We are the plumbers. Space cops and you sir, are going to jail." Says the lead plumber.
"I would like to see you try to take me in." Cell says, laughing at the people.
Plumbers pull out there laser rifles.
"Well if you want it that way!" The plumbers shout.
The plumbers fire a warning shot at Cell who just rounds up to the leader of the plumbers squad and absorbs him.
The other plumbers looked in horror to see their friend die right in front of them. They all charge at him at full speed, but this monster was too fast for them. One by one Cell started to absorb them. But before that, on their last dying breath they gave out a SOS to Ben Tennyson to come and stop the monster. Gwen, Ben's cousin got the message first at the plumber headquarters. She runs to go find Ben and give him the bad news.
"Ben you need to hurry and listen to this!" Gwen says with worry in her voice.
Ben listens to the message and gets a serious look on his face.
"Gwen you think you can help me find what did this to the plumbers?" Ben asks with a very serious look on his face.
"Yeah, I just need to get to the plumbers bodies Gwen said.
"Ok let's get going." Ben said with anger in his voice.
"Where are you two going?" Asked Kevin.
Ben replies "We're going to go look for the thing that killed all those plumbers."
After ten hours of flying to Japan and the three lands, they arrive at the site of the killings. Gwen walks up to the bodies and scans them with mana.
"I found it. It's in a nearby forest. Ben be careful, this monster is strong!" Gwen yells at Ben to make share he gets the point.
Ben hearing that, transforms into Fast tracks and dashes toward the monster Cell. Ben seeing Cell, transforms back to normal and confronts him.
"I will defeat you…umm what's your name?" asks Ben in confusion.
"My name is Cell. I am made of the DNA of some of earth's heroes and an Android.
"Oh really? So your powers are based on DNA too." Ben looks at cell in anger.
"Too? What do you mean too?" Cell questions.
Ben answers, "Well my watch has the DNA of many powerful aliens."
"I have some powerful alien DNA too!" Cell yells.
"Ok that's enough talk, time to fight. I am going to make you pay!" Ben yells, anger in his voice.
Cell says "Ok then, you can have the first hit." Ben touches his new omnitrix and transforms into Heat blast. Ben first starts to make his body hotter and hotter and blasts a big blast of fire at Cell, blowing half the forest away.
Cell with one arm blasted off, says "Not bad boy, you have some power. Now it's my turn." then Cell runs up to Heat blast and a wave of ki energy blasts right in Heat blast's chest. Ben gets up holding his chest and screaming in pain. Ben transforms again and turns into Jet ray. Jet ray flies at Cell at high speeds and blasts Cell right in the face with his nero shock beams coming from his eyes. Cell gets mad at the hero and does an attack called spirit ball on the Jet ray making him crash into the trees and forming a massive crater.
Ben sees that his enemy can do energy attacks and he quickly taps the ominitrix symbol on his chest and turned into the alien Chromostone.
"So is this one more of your famous strong aliens? What is his name?" Cell asks.
"I call this one Chromostone. How about you do some more of those energy attacks and I'll show you what I can do in this form."
Cell being curious to see what this alien can do does a kamahamaha. Sending the attack toward Chromostone.
Chromostone puts one hand up and absorbs the attack and with the other hand he blasts cell right through the stomach.
"Sorry I had to blow a hole in you Cell. I'll get you some help then off to the null void with you."
Ben says what he did though it was over and transformed back to human form.
But Cell gets up, telling Ben this is not over so he hits the omnitrix and turns into Four arms and does a shockwave clap sending Cell back. But Cell did the same sending Four arms flying into trees. Cell flew behind Ben, kicking him into the air keeping him in pain. Ben feeling over powered tried to transform again but could not move. Cell was waiting in the air for Ben to get high enough charges up a big bang attack that sends Ben crashing to the ground. Cell was ready to absorb Ben and the omnitrix when he was hit by Goku and Kevin right in the gut, sending Cell rolling back into some trees. Then Gwen teleported them all out of there to Kamai's look out.
Goku had then healed Ben and he awoke to find himself at an unknown place. He looks around to be surprise hug from his cousin Gwen.
"Are you ok?" Gwen asked her cousin.
"Yeah I'm good. And that Cell guy is crazy strong! What happened to him?" says Ben.
"This guy Goku and Kevin sent him hurtling across the forest before he could absorb you."
"We met him at the ship when you left us and he explained the whole story." Says Kevin.
"Cell reminds me of my race osmaian." Kevin says in a worried tone.
"So your race absorbs stuff?" Goku asks Kevin.
Kevin replies, "Well yeah. We absorb energy but it's illegal for us to do it we go crazy. We can be very dangerous if you absorb too much power."
"I know. I did it before twice and I went evil, but that's a story for some other time." Kevin says to Goku.
"My watch is acting weird. It's pullin me toward you, Goku." Ben says.
Then the omnitrix scans Goku.
Ben the asks, "Are you an alien, Goku?"
Goku answers, "Well, yes me and Vegeta are from a race called the Sayains, a strong race of alien warriors."
"Cool and why are we here?" asks Ben looking around, trying to figure out his location.
Goku answers again. "We are here to train for the Cell games."
"The Cell games? What's that?" asks Ben in confusion.
Goku says "It's a tournament in which we fight to defeat Cell. We have five days till the tournament. We need to win this or Cell wins and destroys the planet."
"Ok, the let's train!" Ben says.
