Disclaimer: Inspired by HVuples Ben 10 Omake stories! I liked the idea of Tarl Zaralka of having Ben with the same abilities as Alucard, but he will still have the Omnitrix (It will be more of a side weapon if things get ugly) and he will still have the things that make him Ben. I just wanted to write my own version of the Ben 10/ Hellsing crossover. This is just a Omake. Idea belongs to Tarl Zaralka.

Disclaimer pt 2: Ben 10 and Hellsing belong to Man of Action/Cartoon Network and Kouta Hirano. Original characters belong to me (I'll try my best to make them believable).

Warning: Dark! Vampire! Ben and this is just a prototype and not the real deal, but if you want to try this out, be my guest.

Crossover: Unnamed Ben 10/Hellsing crossover

Chapter 1

Benjamin Hellsing Tennyson

We come upon a black figure of someone, clearly male, he had dark brown shoulder length hair, red crimson eyes, and wore a long red coat, it was Benjamin Hellsing Tennyson. Suddenly a voice spoke.

"Benjamin! Are you there?" The female voice asked in his ear piece, it was Sir Integra Hellsing, "Do you copy?"

"Yeah, Yeah." Ben said with a bored tone in his voice, Integra was annoyed by his answer.

"Report." Integra said.

"Nothing yet, just a lot of trees and junk..." Ben said still bored out of his mind, "I'll keep you posted."

"Stay alert!" Integra said as she and with that she left. Ben began to look in his surroundings.

'So boring...' Ben complained. He started to walk and began to remember things.

Ben had lost everything, his family and friends. It was the day that Vilgax finally took away everything he had (He killed Vilgax with rage that no one has ever seen before). He still blamed himself for their deaths and left his home of Bellwood, but then everything changed.

He was taken in by Sir Integra and she taught him everything she knew. Including vampires and Ghouls, which are zombies of non-virgins who are bitten by vampires. And also...how to kill them. At first he was against it, but realized it was for the greater good (They were already dead, so it wasn't a bad thing. They could finally rest). He finally had a family again, but he still missed them dearly.

'Gwen, Kevin, Rook, Mom, Dad, Ester...Grandpa.' Ben thought with a saddened expression on his face. He began to walk to his destination.

Meanwhile in an unknown location

A vampire of some sort had a woman in his arms who was struggling to get free from his strong grip. The vampire was male, he had black hair, and dark red eyes. He also had an evil grin plastered on his face.

"You'll make a great slave for me, my dear." The vampire said as he licked his lips hungrily. The poor woman was frightened to death.

"NOO!" She cried. The vampire was about to bite her until.

"Hey, ass-hole!" A voice yelled, The vampire turned to see Ben holding his gun over his shoulder.

"Who the hell are you supposed to be?" The vampire asked rudely "You are interrupting my fun!"

"The name's Ben Hellsing Tennyson! Let the girl go or get your ass kicked!" Ben yelled. The vampire began to laugh and the woman ran for dear life while he was distracted by the new comer.

"You think you are a match for me?" The vampire asked arrogantly, "I'm going to kill you!"

The vampire came in high speed at Ben, but Ben moved out of the way which shocked the vampire.

'I-Impossible!' The vampire yelled in his head.

"Too slow!" Ben said as he slammed his fist in the vampires face sending him flying and hit a wall. The vampire was shocked by this.

"W-What the hell are you?" The vampire asked still in complete shock the this young man's speed.

"I'm from Hellsing and I'm here to eliminate you." Ben said as he activated the Omnitrix and transformed into a ghost like creature with one red eye, red tinted skin with black lines on his body, red colored chains all over him, and a blood red hour glass symbol on his chest. It was Ghostfreak.

"Now lets end this." He said with an eerie tone in his voice as he floated toward the vampire, who had complete fear on his face.

"No! Stay back!" The vampire pleaded, "Have mercy!"

"I'm out of mercy..." Ben/Ghostfreak said darkly as he tore off his second skin, in the distance we hear the vampire scream in complete terror.

Hellsing Manor

Ben had finally arrived back to the Hellsing manor and met up with Sir Integra.

"I see the it went smoothly, correct?" Integra spoke. Ben nodded.

"Yep, mission accomplished." Ben said as he sat on the chair. "I heard you got another job for me, right?"

"I need you to go to Bellwood, USA and investigate any vampire activity." Integra said as she turned to face the young man, Ben had a shocked face.

"What?" Ben said with complete outrage then turned to sadness. "I-I can't..."

"I know it's hard, but it's all in the past now." Integra comforted him (Which was strange for her), Ben closed his eyes to think about it.

"I'll do it." Ben said as he got up and began to walk back to his room, but Integra threw him a blood packet which he caught with ease.

"Seras will accompany you there for your mission, be sure to wake up early to catch your flight." Integra advised him, Ben nodded and started walking to his room. Ben really didn't really want a partner again, after that fateful day, but he agreed none the less. As Ben finally made it to his room he drank out of the blood packet and tasted every last drop. Ben did miss Chilly Fries and Smoothies since they taste like paper to him now, but this was his life, so he just have to live with it.

Beside, not every day you have a really hot girl as your partner. Right?

AN: That's it for this One-shot, but if I get enough positive feedback, I might expand it, but it might be a while though. I had this idea in my head for so long and just wanted to write it out, I just started watching Hellsing Ultimate and I love the series. Also, the winner in the poll is Erza Scarlet for the Ultimate Ladies! But I'll might not write it right away, because I have other girls I want to write as well, but you'll see her very soon.

See ya and be sure to tell me your thoughts!
