Omni-Piece

A Ben 10/One Piece crossover; I woke up this morning with this on my mind, and I had to share it with you all! I hope you enjoy.

It's going to be a task I hope you'll enjoy

NOTE; Vote's are in: Rex won't be joining the Straw Hat Pirates, Rex will ally himself with Luffy though.

NOTE #2; Ben won't always win; he's strong but untrained in the ways of the One Piece world. Just keep that in mind during this chapter.

Rain poured down onto the cobblestone path of Loguetown as Luffy's crew battled against Buggy's crew and the Navy, behind the Straw hat Crew, was Rex and Ben who were knocking out the Navy who were trying to sneak up on Luffy.

"Thanks, Ben!" Luffy says smiling as he knocks out a Navy officer with his fist. Behind Luffy; Zoro and un-named swordswomen were locked in battle as Sanji shouts at Zoro. Usopp was dodging bullets followed by Nami who was screaming at Luffy.

"Get to the ship!" Nami screams dodging a sword swing from a Navy officer. Zoro knocks out the woman with the hilt of his sword, Zoro then runs towards the ship followed by Nami and Sanji. Usopp trails behind dodging bullets.

"GET DOWN!" Rex's voice shouts out; Ben drops to the cobblestone as a smoke covered fist smashes into the wall of a building.

"Kid, why are you wanted?" the smoke-covered fist shifts to show the muscled man with twin cigars in his mouth. His coat soaked with the patter of rain, his glare sent towards Ben who stood back up with his coat arm pulled up to show off his Merge-Model Omnitrix.

"No clue, did my bounty appear one day on your desk?" Ben says sending a smile towards the marine with the twin cigars in his mouth. The man in question was Marine Captain Smoker. Who after getting the snail call was worried and ready to take in the kid before him.

=FLASHBACK=

{BURA BURA BURA}

"Smoker." the man says into a snail; he's pulled out from his coat.

{SMOKER! I have new bounties for you! Why didn't you pick up at your office?}

"Uhuh, new bounties. What about them." Smoker says with an annoyed look on his face.

{Well for one it's a doozie, apparently one arrived on our desk just out of thin air. It's a Kill on sight bounty! For some kid in a green coat!}

"WHAT!" Smoker shouts cutting off the snail call.

"That kid. he's a Kill on Sight. What the heck did he do?" Smoker asks with a vein throbbing on his forehead.

{BURA BURA BURA}

"WHAT!" Smoker says shouting into the snail.

{It's another bounty, this time from Marine branch 16, from that Mouse guy. It's about a Straw Hat kid.}

"The what hat kid?" Smoker asks with a confused look at the snail.

{Apparntly he and that Green coat kid killed Arlong; good riddance I say... bounties are in your office.}

"Him too?" Smoker asks as the snail call ends with a click.

=FLASHBACK END=

"So you and Straw Hat killed Arlong?" Buggy says sneering at Luffy and Ben.

"Nope, just Ben." Luffy says tilting his hat down; Rex looks at Ben who nods. Rex leaves Ben and Luffy to help the rest of the crew with any stragglers.

"Well then, Green coat. Join my crew!" Buggy says looking into Ben's eyes.

"No!" Ben says with a calm voice, Luffy looks towards Ben and then towards the Marine Officer Smoker.

"Fine, then die FLASHILY!" Buggy shouts out sending his fist towards Ben; Ben looks at Buggy and with a sigh slams his hand down onto the faceplate of the Omnitrix; a flash of red and green light blinds everyone but Luffy.

In Ben's place was an armoured-like creature with steam-like pipes that began at the creature's arms that lead towards a helmet that had two horn-like spikes ontop; around the creature's legs was more steam-like pipes that led towards a belt that sat on the creature's waist, on the belt was the Omnitrix's faceplate.

"ARMODRILLO!" the new creature shouts out flexing its arms.

=ALIEN BIO=

Armodrillo, an Armadillo-like alien form from the planet: Terraexcava, Armodrillo's species spend their day's under the planet drilling tunnels that lead towards the core of the planet; luckily for these creatures their planet is always shifting and changing, making more and more ground for the Armodrillo race to tunnel into.

Unlike most Armodrillo who have armour to protect themselves from the harsh heat from their home world's core Ben's Armodrillo form no longer has that armour. Ben's Armodrillo form now has armoured-like skin. Tougher and more flexible.

The pipes that lead towards the armoured helmet regulate the Armodrillo's inner temperature of 800 celsius. The pipes also help the Armodrillo form to tunnel endlessly for days on end.

Unlike Ben's original Armodrillo form, this one has spikes that lead up from its tail.

=ALIEN BIO END=

"Whoa, new form!" Luffy says with small stars in his eyes; around him rest the knocked out Navy crew of Smoker; Smoker's cigars drop out his mouth and Buggy holds his bruised hand.

"OW. OW. OW! That hurt you flashy bastard!" Buggy says rubbing his fist. Alvida looks on with a strange look in her eye.

"Get lost Buggy!" Armodrillo says; his eyes flash from under his helmet.

"I guess I have no chance... CHOP CHOP BULLET!" Buggy shouts out sending his fist off from his wrist towards Armodrillo, who blocks it with his arm.

"OW... OW!" Buggy says bringing his hand back to attach it back to his body.

"Crew... RUN!" Buggy adds; his crew follows leaving behind Alvida; who gives a final look towards Armodrillo/Ben and then walks calmly back towards Buggy's ship.

"AWWW, I wanted to see what you could do." Luffy says with a pout as Ben returns back to normal.

"Straw Hat!" Smoker says; his smoke covered hand grabbing at Luffy's neck.

"Gah! Hey, what did I do?" Luffy chokes out as Ben reaches his hand towards the Omnitrix.

"You're a Pirate, scum of the world and I'm bringing you in." Smoker says throwing Luffy towards the ground; as he does so he grabs his Jutte from his back, he pins Luffy in the chest with it.

"Oh... Ughh I feel ill." Luffy says feeling all of his strength leave him.

"You would it's sea-stone. You and your crew are coming in. Dead or Alive." Smoker says as, behind him, a green and red flash fills the waterlogged streets of Loguetown.

A green-ish hand lands on Smoker's shoulder, Smoker turns to tell the Green Coat kid off; only to not see him standing there; instead in his place was a green-ish crystal creature.

=ALIEN BIO=

Being a silicon-based life form, Diamondhead's body is composed of durable pale green crystals.

He sports four crystal shards on his back and has a sharp head.

Unlike Ben's original form; this Diamondhead has red-tipped crystals and spiked cuffs that surround Diamondhead's wrists.

=ALIEN BIO END=

"Who are you now?" Smoker asks, only to receive a fist in his gut, that sends him back slightly.

'He hit me... that form must be like sea-stone.' Smoker thinks as the new creature helps Luffy up.

"Whoa, new form... wait is this pure crystal?" Luffy asks with a tilt of his head.

"Yes, we don't tell Nami about this form correct!" Diamondhead says locking eyes with Smoker.

"Why?" Luffy asks scratching the back of his neck.

"Do you trust me?" Diamondhead asks.

"Of course." Luffy says with his signature grin.

"Then don't tell Nami. Not until she's not as greedy as she is." Diamondhead says resting his hands on Luffy's shoulder. Luffy nods and just in the nick of time; because Smoker was charging at Luffy with his Jutte raised, ready to knock Luffy out.

"You do not charge at a man when his back is turned." Diamondhead says bringing his fist down onto the Jutte, Smoker watches in shock. Not only di this creature hit him, but it can touch sea-stone and not be harmed by its effect.

"Damn you. WHITE BLOW!" Smoker shouts sending his smoke covered fists into battle with the crystal-like creature who dodges.

"HEY!" Luffy shouts out joining in the fight, only to be knocked back by a smoke covered arm.

"Stay down Straw-Hat!" Smoker says, his eyes locked on Ben's new form; Diamondhead.

"You know I think I'll hit you with this fist." Diamondhead says curling his fingers into a fist, only to miss Smoker as he vanishes like smoke.

"Ha, you missed!" Smoker says blinding Diamondhead with his smoke-like body.

"WHITE WHITE Bullets!" Smoker adds punching Diamondhead with his smoke covered fists; Diamondhead groans as he feels every punch.

"Hey, get off Ben!" Luffy says struggling to get a hit in.

"Hey, Smoker..." Diamondhead says from inside the smoke-like cyclone that is Smoker.

"You should Chill out!" Diamondhead adds vanishing in a flash of green and red.

Standing where Diamondhead stood was a cloak covered creature, its red eyes glow from under the hood and with a shout it unfurls it's cloak; to become two see-through wings.

"BIG CHILL!" The new creature says with an eerie voice.

=ALIEN BIO=

Big Chill is a Necrofriggian from the planet: Kylmyy, they spend their days feasting on the iron that rests in the mines of the planet and causing blizzards that blanket the planet.

Unlike Ben's original Necrofriggian form; this one has see-through wings that wrap around the entire moth-like creature's body to create a cloak that covers the entirty of the alien's form, from head to toe.

The noticeable difference in Big Chill's eyes, are that they are red and no longer green.

Also due to an error during the Omnitrix's merge; Big Chill no longer has an Ultimate form.

=ALIEN BIO END=

"Now Chill out Smoker!" Big Chill says as it turns invisible and escapers from Smoker's vortex trap.

'How the heck does he keep changing!' Smoker thinks to himself as he looks around for the moth-like alien.

"WHOA So cool." Luffy says; Luffy feels a hand on his shoulder and he slightly shivers.

"I agree captain I am so cool." Big Chill says as he becomes visible once again.

"WHITE WHIP!" Smoker screams out striking Ben/Big Chill into a building that collapsed on top of Big Chill

"Ben." Luffy shouts out only to be knocked to the floor with the Jutte once again.

"Your coming in Straw Hat, at least that kid is gone now." Smoker says only to stop as he sees the flash of green and red come from inside the ruins of the building he sent Ben into.

Appearing from the rubble was a creature made of moving rock; that glowed with fire, sitting ontop the creature's body was a floating skull that was on fire; around the creature's wrists was cracked stones that made make-shift handcuffs that seemed to glow with the same fire that flowed through this new creature's form.

"HEATBLAST!" The new creature shouts out as heat travels towards Smoker that knocks him off Luffy.

=ALIEN BIO=

Heatblast is a plasma-based life-form whose body is composed of a super hot inner plasma body covered by a dark red stone's, around the wrists of Heatblast are basalt handcuffs that are just for show.

Unlike most Heatblast kind, their head is always connected to their body; Ben's Heatblast form is not like most, maybe because of the Merge but this new Heatblast form has its head separate from its body; it floats above the body without any trouble.

=ALIEN BIO END=

"WHAT THE HELL ARE YOU!" Smoker asks as he picks himself up from the ground.

"I'm Ben Tennyson, Don't you forget it!" Heatblast says as he shoots fire towards Smoker; as he does so he turns back to Ben with a flash of just red, He grabs Luffy by his vest.

"Run!" Ben adds making Luffy shake himself into action as they escape as Smoker is blinded by the fire.

As fire clears Smoker pulls out the snail from inside his coat.

{BURA BURA BURA}

"I've got a name for the Green coat kid, and a nickname also." Smoker says into the snail with a vain on his forehead.

"We escaped..." Luffy says as he, Zoro, Sanji, Usopp, Nami and Ben sail away from Lougetown; with a grin Luffy leaps up from the deck of his ship, he then walks with vigour towards the hold; and in a couple of seconds, he returns with a barrel of Sake that he places onto the deck of his ship.

"Here today we make our first steps into the Grand Line. We must make a sworn vow, that we will see our dreams come true." Luffy adds sounding mature for once.

Luffy places his foot ontop the barrel of Sake.

"I sware to become King of the Pirates." Luffy says with a grin.

"I sware to become the greatest Swordsman ever!" Zoro adds placing his foot onto the barrel.

"I...I sware to become a brave man of the sea's." Usopp says placing his shaking foot ontop the barrel.

"I sware to draw a map of the world." Nami adds placing her foot ontop, she looks towards Sanji who's trying to get a peak of her panties; she punches him on the back of his head.

"I swear to find the All Blue!" Sanji says with a lump on the back of his head.

"Ben?" Luffy asks looking towards Ben whos sitting on the railing of the Going Merry.

"Oh... I don't have a dream right now, but when I do. I sware to never fail!" Ben says, andfeeling thats enough for now Luffy returns the nod, and with all of his crew together they smash the barrel into the deck of the ship as a promise to follow their dreams.

No matter what!
