Halloween Horrors

A Ben 10 Fanfiction


I'm taking a new approach with Ben 10, like I did with some of my other stories.

After the long summer of fighting aliens...Ben can't wait to use the Omnitrix for trick-or-treating on Halloween. And he makes a huge mistake and uses...Ghostfreak.

And, now, Ben can't return to human form.

I DO NOT OWN Ben 10!!


Prologue: Four Years, Thirty Lives

So it has been four years since the summer that changed young Benjamin Tennyson's life. Now, at fifteen years of age, he has become a bit more mature with the Omnitrix, as well as already unlocking the Master Code and a few other aliens. He still keeps his careless attitude, and his carefree attitude, not listening to anyone about anything.

The aliens he has acquired over the years has been gradual, nothing compared to his first year with the Omnitrix. Now, at a total of thirty aliens, nothing can face him. The future of Ben 10,000 is growing closer, but none yet know who he is...

He has, indeed, become quite the hero.

But even heroes make costly mistakes, ones that always change their lives.

Ben sighed and turned off the computer. His grandfather, for Christmas of 2009, had given him a special laptop—courtesy of the Plumbers. He had enlisted the assistance of several original Plumbers to give him info on the aliens on the Omnitrix—thus, the Omnitrix Alien Log was created.

That first school year with the Omnitrix was hell. He found it hard to balance school work and hero duties. He had informed his parents about his newfound powers the day he was returned, and they agreed to help him. Max helped by making them Plumbers, and also restarting the 'nonexistent' Plumber's business.

It was getting to be like the future Ben and Gwen had seen. A recent clash with Charmcaster and a teenage Hex left Gwen in charge of the newly resurrected Charms of Bezel, like her future form Gwendolyn. She wore them on a belt, always hidden under a shirt.

No one normal knew of the Omnitrix yet, though. Ben would tell the world when he knew the time was right.


Ben just sat on the ground, watching his cousin destroy self-made targets with magical energy bursts. The field was the perfect place for her to train magic, and she even tried to use Ben as a target—if he was an alien.

"Ben, c'mon!" he heard her shout. "Go XLR8! I wanna see if I can hit you!"

Ben just sighed, and with a flick of his thoughts, turned into XLR8. "Why are you using me as a target?"

"You're no fun anymore," Gwen scoffed. "Ever since you reactivated the Master Code on that thing, you've just become...boring."

"Good," Ben/XLR8 said. "Then we're the same."

He smirked as she murmured an incantation and bursts of flame shot out at him. Dodging them with ease, he yawned.

"Is that the best you got?" he asked.

Gwen frowned. With a flash of green light, Ben became the alien known as Spitter he had seen in the future. He had acquired it not too long ago. Taking a deep breath, he spat out, drenching Gwen in the yellow spit.

"EWW!" she screeched, waving her arms to throw the stuff off. "You're gonna pay for that, dweeb!"

Ben/Spitter grinned. Then, in a gurgly voice, said, "I have no money, ma'am. Would you like that in a check?"

Gwen yelled and ran at him straight on. He grinned once again and became Mudpuppy. He raised a purplish mud arm, the shadow of it covering Gwen's body.

She got the hint and backed off. "Fine, you win."

"I always do," Ben/Mudpuppy said.

He suddenly blinked. He had heard...a voice. It said something, but he couldn't understand him.

His cousin's voice brought him out of his thoughts, "...is coming up. What are you gonna be?"

"For Halloween?" Ben/Mudpuppy asked.

"Duh! I'm going as a witch. What about you?"

With a green flash, Ben turned back into his human form. He looked to the horizon and said, "Ghostfreak."


I am Benjamin Tennyson. And this is the story of the worst mistake I ever made.


Damn, this was on a tight schedule. I wanted him to have thirty aliens at the age of fifteen, so I used some of the aliens from Ben 10K, and some other people and I made up.

I own Dragonfire, Razorblade, and Tempus. Zfish9 owns Waterpump. Thank you for letting me use him! And the TV . com user DbzOrDie owns Kamekalion.

Yes, I guessed on some of the aliens' home worlds and species, like Benmummy and Ditto. And I made up a few, and grabbed some of the known aliens—like Gluto—and did the same.

And the date may be a bit sketchy. I am assuming it is the year 2007 in the summer he got the Omnitrix, so I took it from there.

Sorry if Ben and Gwen seemed OOC!

Enjoy!
