Author's Note:

Final chapter for Ultimate A! I'm thinking of writing a sequel for this story called Ultimate Machine but I'm basing making a second one off you guys, if you want one just say so and I'll continue.

Also if I do end up making a sequel the same OCs you saw in this story will also be reappearing in the second and two more spots are opening up for two new ones, and sorry to you guys who already sent one in for Ultimate A, I'm only allowing one per person excluding myself.

There will be some blood in this chapter.

Enjoy!

She peers up at the mid-day sun squinting against its heated glare, glancing at the red car beside her she crosses her arms over her pink armored chest, "Are you sure is where he'll be?" she questions the vehicle.

"Positive, last time I checked his microchip informed me that he was going 220 and heading southeast, thus landing himself here," the car says firmly making the Chipette raise an eyebrow at it's smart tone, "Microchip?" she echoes.

"Yes a small computer device usually put in dogs to let humans know where they are or where they belong. The scientists got this idea after Ultimate ripped his tag out, of course he can have the chip removed but it is as small as a gain of sand and requires a laser," the car explains, she purses her lips remembering seeing a cut in his left ear.

"Oh so that's where the cut came from," she says out loud grinning at her discovery, "Oh good job," the car replies sarcastically, narrowing her eyes she opens her mouth to reply with a smart retort but a strong gust of wind nearly sends her tumbling into the desert sand.

Whirling around her arm whips forward suddenly nearly colliding with his nose, his fist coils around her's and he smiles at the stunned expression on his counterpart's face.

"I didn't do that!" she exclaims waving her free arm around wildly trying to gain her balance as he carefully releases her paw, "I know the armor enhances your reflexes," he informs her as the car's door swings open and it's metal arms snake out holding a red armored suit similar to Brittany's except it has a yellow 'A' spray painted on the front and it looks thicker and heavier.

"Thanks Cal," the russet furred chipmunk chirps allowing the arms to slip the futuristic armor over his head and arms, "You are welcome sir," the car replies cheerfully.

Brittany huffs and crosses her arms over her chest, "You two are buddies huh?" she questions resisting the urge to ram her new boots into the car's side.

"Yeah he was created and programmed just for me, he's a robot that can transform into any device, weather it's a car, or even a calculator," Alvin explains tapping Cal's hood as the arms place a red helmet over his head.

"No fair," Brittany grumbles glaring at the car that simply seems to snort in her direction, if that's even possible.

Alvin doesn't say anything, his eyes are fixed on the horizon his mouth set in a firm line, Brittany slowly uncrosses her arms and curiously follows his gaze, her heart begins to race and a horrid feeling inches over her spine sending her fur into a frenzy under the armor.

A dark silhouette rises over a crest of a sand dune, the sun shines brightly over head casting the figure in a dark shadow, Brittany shifts behind her counterpart's stiff body placing a paw on his arm she peers up at his expressionless face.

"Is that your dad?" she whispers her voice hushed.

"Yeah, Ultimate Beast," Alvin answers practically spitting the name out, Brittany returns her gaze back to Beast, she screams and stumbles back as dark golden eyes pierce her's.

"Aw why doesn't she like me?" the older chipmunk whines staring with mock hurt at Brittany's trembling form behind Alvin, "It's ok little one," he purrs reaching out to touch her, Alvin's paw flies up blocking the black furred chipmunk's sharp clawed paw.

"Don't, she's only here to help me," Alvin growls protectively his eyes taking on a dangerous gleam of red, " Oh you're Linked, I see," Beast straightens up studying his son's armor curiously.

" I see you've heard of my abilities," Beast muses narrowing his eyes in Cal's direction as if he were blaming the car, "So?" Alvin grumbles irritably.

Brittany peeks around Alvin's arm bravely, studying the dark furred chipmunk standing in front of him, he has a dangerous air about him that sends her mind into a whirlwind, Beast catches a glimpse of her bright electric blue eyes and grins flashing needle sharp teeth, "Now two against one isn't really fair," Beast mumbles pouting.

"She's not fighting," Alvin, snaps, Brittany frowns peering up at her counterpart in confusion, "Then why am I dressed like this?" she demands bravely stepping out from behind him to narrow her eyes at him.

In a blur of black and russet Brittany is shoved backwards and into the front seat of Cal, the car slams the door closed and wraps the seatbelt twice around Brittany before hitting the gas and speeding out of there.

"Hey! What's going on?" Brittany cries struggling to get free, "He's protecting you," the car answers, "Then why did he bring me?"

"To break the Link in case he dies,"

Alvin is a monster, yes, but Beast gives monster its true definition.

His body is a cross between a gorilla and a horse, his chest begins to expand to the size and strength of the large ape, his black fur becomes short and crisp ending at his waist where thin moss green fur covers his flanks. Rhino like ears crown the top of his head and the skin behind them splits open allowing large white horns to break through, the gold melts from his eyes turning a dark inky black that completely consumes the white. His muzzle twists and lengths taking on the shape of wolf's, a hawk beak takes the place of a large wet nose, his muzzle fills with sharp teeth his canines lengthening until they completely hang down pas this mouth resembling a saber tooth tiger's.

His arms lengthen each one a mix-match of different animals, grizzly brown fur sprouts out from his skin starting at his shoulder and ending near his elbow, his forearm is covered in a hard exoskeleton of an Emperor Scorpion; his hand resembles a gorillas except it's covered in the exoskeleton and short sharp claws extend from his fingers and thumb. His left arm starting at the shoulder and ending at his elbow becomes covered in rough skin reminding Alvin of a rhino and for extra measures a horn extends from his elbow, below short dark brown hairs cover his skin looking that the hair found on a large tarantula and his hand looks like an owl's.

His hind legs bend and twist forming to look like a dog's hind legs, the right leg from hip to knee is covered in thick shaggy black fur, from the knee to ankle joint the skin fades to resemble a armadillo's hard thick plates, feathers covert into an orangutan hand. Cheetah fur covers the top half of his left leg fading to centipede skin at the knee, then an artic fish, followed by the slick feather of a penguin and his hand is similar to a chameleon's. Anaconda skin covers a long snaking tail, at the very tip it forms and folds into a triangular shape as hard as bone and as sharp as a glass.

Alvin's tail whips back and forth behind him giving away his nervousness as Beast towers five stories over him, "You truly are a monster," he sneers as bat wings slip out just behind Beast's shoulder blades, "I'm glad you approve," Beast hisses his voice deep and demonic changing pitches at certain places, sounding like an angry man one second and a haunting child the next.

Alvin had shifted as his dad did, his body only increases to the size of a large dog and the red armor seeps to melt into his skin, he looks just like he did when he killed Peter.

"To the death, that is part of our deal," Beast reminds the small cat like form of his son crouching before him, "I'm surprised you remembered," Alvin snickers darting forward like a bullet from the barrel of a gun.

Beast's large body slows him down allowing Alvin to deliver the first blow, he propels himself upwards raking his claws straight down Beast's mighty chest leaving behind gaping wounds, the monster roars in discomfort and lashes out with a giant hand, Alvin uses Beast's massive chest as a back board. He pushes himself backwards and into a back flip barely dodging the sharp tips of Beast's claws.

Beast staggers slightly caught off guard by the power coiled inside the mutated chipmunk, he curses inside his head when he remembers one thing that the scientists failed to add to his abilities and that's to heal quickly.

Thinking quickly Beast shrinks his body in a matter of seconds becoming roughly the size of a horse, he suddenly charges expanding his wings out he swerves to the side and disappears, Alvin's eyes widen as he whips around trying to pinpoint his dad.

The air ripples right behind Alvin's left ear, it twitches catching the sound of the air vibrating but it's too late, Beast strikes out catching Alvin's entire left side with a hidden stinger in his wrist, the massive sharp object easily slices open the armor and even the top layer of Alvin's skin.

Reacting quickly Alvin whips his tail around coiling it quickly around Beast's entire right arm he jerks his tail and his entire body to the side snapping all the bones in the monster's arm and breaking off the stringer.

Beast roars in rage and races forward ramming his horns between two of Alvin's ribs easily breaking them, Alvin hisses at the fresh dose of pain but merely pushes it to the back of his head, a spider leg jams itself into Beast's left eye.

"AGH!" Beast stumbles back clutching his throbbing eye, blinking rapidly his ears pick up on the shifting of sand, out of the corner of his eye he catches sight of his broken stinger, grinning crookedly he snatches it up and twists around ramming the pointed tip right through left shoulder blade, the sound of crunching bone fills their ears as Beast twists the sharp weapon through and through the armor and bone.

"DUCK!" out of no where a large bat descends on Beast's head clawing wildly at his eyes, Alvin tips onto his front paws ignoring the pain he kicks backwards like an bucking horse slamming his powerful hind paws right into Beast's unprotected belly.

The impact sends the horse-sized monster flying through the air before crashing into the desert sand, Beast staggers quickly to all fours, "Quick keep him in place!" Nathan cries from the air.

Alvin presses a button on the arm of his armor spikes shoot out of the back of the armor, Alvin races forward his paws kicking up sand as he dead out sprints across the sand, ducking between Beast's front legs Alvin arches upwards ramming the 20 inch spikes deep into the monster's belly and chest.

Beast roars his pain up into the mid-day sky, suddenly a putrid liquid is dumped all over him, some of it leaks onto Alvin, "RUN MAN!" Alvin quickly ducks to the side snapping the spikes off in Beast's flesh at the sound of Max's voice from above.

Stripes lights a match and drops it onto the gasoline-covered monster, his entire form bursts into bright orange flames, Max grins and touches knuckles with Stripes, "Gasoline always works," she chirps settling black tinted sun glasses onto her nose as Stripes rainbow colored eyes reflect the dancing fire.

Beast stumbles forward roars of immense pain escaping his dripping melting muzzle, his eyes are wide behind the wall of flames and he can still see, Alvin backs away a small grin playing on his face as he watches the monster burn.

He turns ready to head back home when he feels the heat of the flames at his back, "LOOK OUT!" Stripes screams, Alvin whirls around his golden eyes widening in horror as Beast rams a large saber tooth straight through his chest.

In the blink of an eye Beast's entire body turns to ash, smoke rises from them and a few stray flames flicker and dance over the black thick powder, Alvin's body shrinks collapsing in on itself until he's back as a chipmunk standing on shaking legs blood leaking from a corner of his mouth, a huge gaping hole fills his chest, blood spills down the red metal of his armor.

Nathan flies over landing right beside the wide-eyed russet furred chipmunk; "H-he's dead, haha he's dead," Alvin chuckles resting a paw just below the huge hole, "Ugh, that's going to hurt in the morning," he groans shaking his head, trying to keep the pain at bay.

Nathan stares at the chipmunk in shock, "I was supposed to kill you, my enhancements were to help me kill you," Alvin turns with narrowed eyes a curious expression on his face.

"Why didn't you?"

Nathan expands a wing, images of Alvin's family appears on the membrane of the bat's wing, "You have so much to live for," he explains folding his wing back into place.

"ALVIN YOU IDIOT!" Brittany rams right into Nathan's back and falls flat onto her butt, the bat gives her an annoyed look over his shoulder, "Why did you do that!" Brittany yanks her helmet off the screen that protected her eyes was completely black like someone colored it in with a sharpie.

She squints against the glare of the sun, her gaze travels from Nathan to her counterpart, horror quickly washes over her face and the helmet falls from her paws, frowning Nathan follows her gaze just as Alvin's body crumples to the ground.

"Alvin!" Brittany falls to her knees rolling him over onto his back quickly, "Max! Stripes we need a first aid kit fast!" the two Chipettes quickly scramble off in search of Cal as Nathan turns back to the shaking chipmunk.

"My arm and leg, I ca-can-t," blood foams at Alvin's mouth as his right paw clings onto the exposed flesh of his left arm, his body convulses wildly and a scream rips out of his throat at the insane paralyzing burning racing through his body.

"Make it stop!" Brittany demands yanking the chest plate off she rips the sleeves of her dress off and desperately begins to try and stop the sudden profuse bleeding, "Stay with us Alvin," Nathan demands ripping at his orange jumper and tying up the wounds quickly.

A weak chuckle comes out of Alvin's mouth, "Y-you used my name," he mumbles as he reaches out weakly to grasp Brittany's paw in his right one, Brittany fights back tears as she uses her free paw to apply pressure to his wounds, Alvin's mouth opens slightly and he swallows roughly trying to tell her something.

"Don't cry over me," he hisses as the fire in his golden eyes fades, his paw tightens for a moment then falls limp, the sand drinks up his blood eagerly.

Nathan gasps in shock and looks up at Brittany, the Chipette stares blankly at Alvin's closed eyes and lax face, the bat slowly stands his paws soaked red as Max and Stripes slow to a stop the first aid kit clutched firmly in Max's paws.

Nathan shakes his head and turns away just as tears spill from Brittany's eyes.

Ultimate A, is dead.
