Disclaimer: I do not own Ben10. If I did, do you honestly think I'll be writing fanfictions.

Me: Hi, everyone. This is a rewrite of my first fanfiction. This is also the start of the fanfiction series I've been during for the past one year. You'll have to read this story to read the other ones so you can understand very well of the story. This story is also based after the eleven year old Ben 10 from Ben 10: Omniverse, though there is a slight change in it. Due to the fact that I wrote the original of this story before Ben 10: Omniverse was out, Ben's parents will know about Ben and the Omnitrix. Ben never gave up the Omnitrix either. Now that I;ve cleared those up, read and enjoy.

Chapter 1: The adventure starts

It's been two years since Ben Tennyson defeated the alien warlord Vilgax and things have gone well for Ben, Gwen and Grandpa. They kicked aliens and evil mastermind's plans over the years before things started to get normal. There were still the occasional villains returning to get revenge on Ben and Gwen, but it had begun to cease.

However, on their way to school, they were ambushed by Charmcaster.

Gwen got into a fighting stance, her fists powering pink like orbs, "Can't you take a break from the whole trying to kill me routine. It's getting very old."

Charmcaster stood before them, glaring at the duo, "Not until I see you and your cousin dead." Her hands powered up pink like orbs like Charmcaster as she got ready to cast a spell, "Snora bent chota."

Suddenly, plant like vines sprouted from the ground, trapping the duo Tennyson. Gwen got ready to fight them when suddenly there was a flash of green light. When the light died down, standing in Ben's place was a semi-velociraptor with black balls under his feet, a helmet with a visor on his face and a tail.

"XLR8!" The alien shouted. Immediately, he ran straight at Charmcaster as a fast blur, avoiding the vines from attacking her. Some of the vines tried attacking him, but they weren't fast enough to catch him. XLR8 drew closer to Charmcaster, but before he could hit her she flew up to the air. Charmcaster motioned her hands down at Ben, causing the road to melt and trap XLR8 wheel like legs.

She then waved her hands at a few vines, motioning them to Ben. The vines did as commanded and began wrapping itself around XLR8. However, Charmcaster was too distracted that she didn't notice until Gwen delivered a fly kick to her face. She was knocked to the ground, allowing Gwen the chance to run to hern cousin.

"Amora denshaa!" Gwen shouted, casting another spell. The vine bonds holding Ben instantly unwrapped from his body, freeing him. The sticky road was also cemented back to normal and Ben ran to his cousin's side. Gwen turned to her side, seeing her cousin and smirked, "Are you ok, Ben?"

"Always." Ben answered. He turned to face the herds of mutant vines heading to them and smirked within his helmet, "Now let's take her down."

Hovering above them, Charmcaster casted an angry glare down at them, "I don't think so! Both of you have embarrassed me for too long and I've had enough of it!" She pushed her hands forward, commanding the mutant vines to grow longer and larger.

Gwen and Ben got ready to fight, seeing that another fight was coming. Instantly, Charmcaster clutched her fist tightly and the mutant vines charged at the Tennyson duo. Gwen fought back, throwing mana blasts at the vines and using her karate skills to dodge the attacks. Ben used his enhanced speed to dodge most of the vines and then cutting them with his scissors like hands.

However, the number of vines was increasing despite Gwen and Ben's effort. The duo found themselves trapped in a circle with the vines furiously attacking them. Ben continued to cut them down with his scissor like hands, but even his speed couldn't keep up for long.

Suddenly, a familiar sound of a car horn brought hope for the cousin. They looked at the direction the sound came from and saw the Rust Bucket driving to their way. On top of the vehicle, two alien tech guns fired at any surrounding vines, allowing the vehicle to pass through easily. The Rust Bucket stopped before them and the door flung open to reveal their Grandpa, Max.

The old man looked straight at them with a serious look, "Get in!" He urgently said. Gwen quickly obeyed, running into the car. She ran into the vechile when she noticed someone was missing. She turned back to the field of mutant vines.

"Ben, get in here quick!" Gwen shouted to her cousin. Ben ignored her and continued cutting through the mutant vines. He was too determined to cutting them that he didn't notice the Omnitrix symbol beeping. With a final beep, he was engulfed in a flash of light that changed him back to his normal form.

The moment he was human, Ben took a look at himself, surprise that he changed back. He quickly began to the Rust Bucket, "I'm coming." But then a group of vines surrounded him, blocking his path to the vehicle. Seeing his grandson in trouble, Max focused the laser guns at the vines and fired. However, the vines grew, delivering him to Charmcaster.

"Look who tried to escape." Charmcaster smirked. She looked away from Ben and then motioned her vines at the Rustbucket. The vehicle, however created an electric force field that surrounded it. Any vines that tried to attack the Rustbucket were immediately electrified to dust.

Watching her attack fail, Charmcaster grew very angry that her eyes glowed bright pink, "No! I WILL NOT FAIL!"

"Then don't bet your luck, Charmcaster." Gwen shouted, standing at the open door of the Rustbucket. She got into a stance, pulling her hand backwards as he hand glowed pink. She took her short time to calculate her throw and then swiftly threw it out of the vehicle. Her pink blast sawed through the vines like a boomerang, heading to Ben. It cut through the vines holding Ben, freeing him and letting him to fall to the ground.

With nothing holding him, Ben began to fall, screaming. Before he hit the ground, a pink platform appeared underneath him, saving him. It then flew Ben to the Rustbucket with Ben clinging on to it with safety. Luckily, the force field surrounding the RustBucket allowed the platform to phase through. As Ben got inside, he saw Gwen with pink eyes and hands pulling him inside.

Ben got back to his feet as the platform. He met the angry glare of Gwen and smiled sheepishly to her. Grandpa Max quickly told his grand children to get seat before driving off. As soon as Ben and Gwen did as he instructed, with Ben sitting at the passenger seat, he drove the car out of the field of mutant vines.

Just as the Tennysons left, dozen Plumber aircrafts flew above the field of mutant vines and began spraying gas substances. Gwen loked through her window and smiled, seeing the mutant vines dying. But then a panic look formed on her face as she saw Charmcaster burst through the dying vines and heading straight to them.

"Grandpa, Charmcaster at 6 O' clock!" She shouting, alerting her cousin and grandfather.

Charmcaster was able to catch up to them, forming a pink blast in her hands. She then shot the blast at the RustBucket, destroying the force field surrounding it. Max quickly reacted quickly, pressing a few buttons at the driver's seat. Two laser guns pop from the top of the vehicle and began firing Charmcaster. However, she created a pink square shield, avoiding the lasers. She put the shield down and shot to mana blasts at the guns, destroying them.

She wasn't done as she shot the tire of the Rustbucket, causing it to spin before coming to a halt. Max, Gwen and Ben looked through the window, seeing Charmcaster charging up her fists.

"What do we do now?" Gwen asked.

Before Max could utter a word, Ben spoke up as he activated the Omnitrix, "Going hero!" He found the alien of his choice and slammed the watch. His entire body was engulfed in green light. When the light died down, a ghost-like alien, with claw like hands sat in Ben's place. He had grey skin with black lines running all over him.

"Fourarms!" He shouted in a ghostly voice. Realizing the tone of his voice, Ben glanced at himself and sighed, "Sometimes I really hate this watch." Before Max could stop him, Ben pashed through the ceiling.

Charmcaster saw Ghostfreak floating before her and smug, "Stay out of the way, Tennyson. This is between me and your stupid cousin."

"Yeah, that's not going to happen." Ben said and became invisible, "Besides you have me to fight." The smug look on Charmcaster's face grew into a smirk as she knew exactly what to do. Her eyes brightened a flash of pink light before it died down. She looked around her and saw Ghostfreak behind her, preparing to throw a punch, "I see you." Before Ben could react, she fired a Mana blast and it sent him crashing to the ground.

Ghostfreak groaned, getting off the ground, "How could you see me?" He tried becoming invisible, but couldn't. No matter how much he tried to become invisible he stayed visible.

"It's simple, twerp."Charmcaster flew lower to him, "I shot a spell that immbolizes you powers, so that means…." She forwards her right hand straight him, "I can do this." She then fired a mana blast at Ben. Even though Ben was like a ghost, he could feel every part of the pain on him. He let out a scream as Charmcaster increased her power level.

"Hey, leave him alone!" A voice interrupted him. Charmcaster stopped her attack, her smug turning to a grin. Just as she turned behind her, a mana blast hit her that put her to sleep. Ben let out a moan as the watch timed out and returned him back to normal. He got off from the ground, feeling better than before.

"Thanks for the help, Gwen." Ben smirked, "But I already had her where I wanted."

Gwen gave him an angry look and slaps him at the back of his head, "You're such a doofus! You nearly got yourself killed!"

"She's right, Ben." Max stepped in, "Charmcaster was ready for everything. I thought you learned your lesson about team work three years ago, but I guess it was short lived. We'll talk about your punishment with your parents. I've called the police so they can arrest Charmcaster. They should be here before she wakes up." Ben didn't say anything, other than bowing his down with a frown. Max led them to the Rustbucket and they drove off.

Meanwhile, in the dark and green area of a dimension called the Ghost Zone, a giant and magnificent castle stood on a floating island. Within the many rooms, a figure dressed entirely in a dark cloaked watched the entire fight the Tennysons went through. He remained silent throughout the entire battle before it went off and he sat on a throne like seat.

"Exactly as I expected, Ben Tennyson is weaker. I shall final be able to take over the Multiverse without his interference. But I will not underestimate him…again."
