ALL I COULDN'T GIVE

Summery: Twenty years is a long time to be holding a grudge. As Devlin found out when Kevin escaped the Null Void for his revenge. Without his adopted father or Kenny to rely on, how is he going to save the world?

Rated M, takes place in the future.


CHAPTER ONE: THEIF

"Nice to see you again, Kevin."

Kevin got up from his chair, or more like throne of corpses. He turned around and stepped over the bodies of various aliens that were slain by his hand. The Aufnehman look at the man who approached him, "Ah Owen. Come to visit me again? Now what do I owe this visit too?"

An adult Owen stood before Kevin, like he did at least every other week. The Ex-Necrofriggian was the only person who bothered to see if he was even still alive. Kevin watched the man like a hawk. He had changed so much while he was locked away. The boy had grown up. He was tall now, slender, but with a well-toned muscular body. He had grown out his hair, it was long and shaggy, complete with a light five-o'clock shadow over the lower part of his face, thicker at his chin. His green eyes glared into Kevin's soul. He hated it every time he looked at him. Those eyes were exactly like his fathers…

…Exactly like the real Ben…

"I came to see if you were still living in this hell hole." Owen muttered, looking around at the dismal surroundings of the Null Void.

"And yet you never let me out." Kevin grumbled.

Owen shook his head. There was no way he was going to let Kevin out. Just looking at the other man almost gave him the shivers. The Kevin he knew, the one that went out of his way to protect his friend, was long gone. In his place was this long haired, leather-clad monster seeking only revenge. "I can't do that Kevin. You'll only cause trouble."

Kevin stepped towards Owen with an angry determination. The other did not budge, he knew Kevin would not hurt him. He was the only shred of humanity Kevin had left, the closest thing to a friend. Even though, Kevin marched right up to him and looked him in the eyes. Owen held his gaze, giving the taller man a mocking smile.

"All I want is to kill that impostor and have his hide stretched on my floor and his head mounted on my wall." Kevin growled. Owen continued to hold his gaze, and those cursed green eyes of his finally got to Kevin. He withdrew, stepping away from the other.

Owen folded his arms, looking over at some alien eat another one, "No matter how much I want to agree with you, its not possible. Even though Ben 10,000 is an impostor, he is currently the only Ben. At least he's using his powers to help people. The world needs him, whether we like it or not."

Kevin wanted to strike Owen, but he couldn't muster up the courage. He turned away from him, "I don't care! I will get out of here! And I will get my revenge!"

"And how do you plan to do that?" Owen snapped, "Come on Kevin! As long as you keep up that attitude, you'll be in here forever!"

"Leave!" Kevin bellowed,

"Kevin." Owen growled,

"LEAVE!"

Owen sighed, "Fine. I'll see you later." He turned and walked away, leaving Kevin waiting within his coffin of corpses.

"Tennyson!"

A brown haired, green-eyed boy flinched as two larger boys walked up behind him. He was small, only a child. He wore a white shirt, with a black scarf tied around his neck, and baggy cargo pants. He clenched the straps of his black and red backpack tighter as they approached.

"You weren't in the designated 'meeting spot' this morning." One smirked, slamming one fist into his other palm menacingly,

The boy flinched and turned around, "Uh…hi guys. I um…really need my lunch money today, so could you please cut me some slack?"

The two looked at each other and laughed. One stepped forward, grabbing the front of the boy's shirt and lifting him into the air, "What do we have here Phil?"

"I think we have a wise-guy Doug." The other sneered,

Doug raised his fist into the air above the boy's head, "I don't like wise guys."

"W-wait!" The boy gasped, "I-I-I'll give it to you! Just don't…"

"Just don't hurt me." Phil mocked in a girly tone.

Doug punched the boy in the face and threw him against the lockers, "Well Tennyson, cough up the cash."

The boy dug hurriedly into his pocket and pulled out a five dollar bill, holding it out.

Doug grabbed the bill and kicked the boy in the ribs, "That's for holding out on us."

Phil kicked him again, "Yeah! See you at the meeting place tomorrow."

Doug laughed as he walked away, "For someone with the last name Tennyson, he really doesn't live up to that name."

The boy gasped out in pain as he lay on the ground holding his side. He barely saw the brightly colored feet of a girl walk up to him.

"Gee. You should have just gone to the far wall of the school like always."

"Oh…hey Lydia." He huffed, leaning up.

A girl with bright red hair and a face full of freckles looked down at him through the rims of thick glasses. She smiled and helped him to his feet.

"Forgetting about me already?"

Lydia and the boy looked over as a tall, lanky, skinny boy walked over to them. He wore an oversized backpack and shoes that were much too large for him. He matched that with tight jeans and a neon-pink shirt.

"Joel, give Kalvin a break." Lydia snapped,

"Hey!" Joel replied, flipping open a compact mirror and looking at his reflection in the glass, "Its his fault for not going to the meeting spot."

Kalvin rolled his eyes, "Come on…we're late for class."

"TENNYSON!"

Kalvin sighed as he walked into his classroom. The homeroom teacher stood angrily at the chalkboard, glaring at Kalvin as if he could strangle him with looks.

"You are late. AGAIN!" He snapped, "Take your seat and prepare for detention."

Kalvin did not try to argue, or get out of it by telling him he was late because he was busy being beat up. He tried that before, and arguing only extended the detentions, and tattling only got the beatings worse.

This was just typical life for him - and all because his last name was Tennyson. It wasn't fair. He thought bitterly, "You'd think everyone would love me because of my last name, not bully me."

~ * ~

Kalvin waited by the front of the school. It had nearly been an hour now, and yet again, his dad was late. His older sister stood next to him, not a care in the world. He wished he could be like that, pretty, popular…and have powers.

He looked over at his sister, Tessa. Tessa was beautiful, she had long brown hair that when let down, flowed down her back, and striking yellow eyes. Today, her hair was up in a pony tail, and she wore a mix of black skirt, red top, and black vest, with matching boots and stockings. At only nine years old, she was nearly the queen of their elementary school. Even the old kids liked her.

But it was her powers that made her extra special. Unlike him, Tessa took after their father, who was finally arriving now in their car. At least it was a nice car, a beautiful red mustang…with several dents in it.

Owen smiled as he looked over at them, "Hey kids! Sorry I'm late! I had some business to take care of."

Kalvin rolled his eyes, "Yeah. Like ALL the time."

Owen frowned, "Hard day at school?"

Kalvin opened the door and climbed into the back seat, "What gave that away?"

"Someone pee in your grapefruit or something?" Tessa laughed.

Kalvin cringed. Sort of…but he wasn't going to tell them that.

"Daddy guess what I learned today?" Tessa gasped, digging into her backpack,

"What is it sweetheart?" Owen smiled, pulling away from that cursed school,

"I learned that Kenny Tennyson, you know, Ben 10,000 son, his birthday is next week! He's turning ten and his parents are throwing him a huge party!"

"That's nice honey." Owen replied, trying to keep his tone indifferent, but his fingers tightened their grip on the steering wheel.

"Well, my tenth birthday is coming up soon." She grinned, "And I want a big party too!"

"Nothing too big. You know your mother's not doing so well."

Kalvin shrunk down into his seat, folding his arms tighter. Right, their mother was not doing so well. She is very sick. Dad wouldn't tell him what was wrong with her, only that we should keep up hope. But even Kalvin had to admit it, after she was hospitalized and nearly unconscious for over a month now, he was starting to think she was never going to get better.

Dad also went downhill after she got sick. He used to look so suave, his hair nicely kept, always nicely shaven…but now, it looked as if he hadn't shaved in days. It disturbed him, especially since his favorite saying was always, "Cleanliness is important no matter who or where you are." Kalvin closed his eyes, and that was why the dishes hadn't been done, the laundry was piling up, and the house smelled like stale coffee and medicine.

Kalvin suddenly wished for a time when their Mom would always pick them up after school on time, make them bag lunches to avoid the bullies, and their Dad would give him shoulder rides around the house…

"I know things have been harsh since your mother became ill, but I promise you, I will do my best to make things right." Owen said, turning off the highway and into a residential area.

"That's what you always say." Kalvin sighed, as Owen slammed on the breaks.

Kalvin gasped as he was thrown from his seat, slamming his head against the seat in front of him. "Not as bad as having it slammed against a locker." He thought bitterly before looking up to see why they stopped.

A woman stood before the car, she looked shocked as Owen climbed from the car.

"Haven't you heard of crosswalks? Jay-Walking is illegal!" He snapped. Kalvin mentally gulped, good old Dad…a small town policeman to the heart.

The woman blinked, "I'm sorry…wait…you look familiar…"

"Daddy look!" Tessa gasped, "Its Gwendolyn! It's the real Gwendolyn! Ben 10,000 cousin!"

The colour completely drained from Owen's face.

"Owen?" Gwendolyn gasped, "Is that really you?"

Owen sighed, "Its been awhile Gwen."

"What happened to Aunt…" She stopped herself when she saw the look Owen gave her, "Anyway, I go by Gwendolyn now. It got too confusing between me and Gwyn."

"And I'm guessing Gwyn is short for Gwyneth?" Owen asked,

"Yes. You should see her. She's grown into quite a lovely young woman." Gwendolyn nodded, "So, are you going to show me where you're staying, or stare at me dumbfounded?"

Owen just pointed to the car. Tessa gleefully hopped to the back seat to let Gwendolyn have the front. She pushed Kalvin over roughly.

Great. Owen sighed, twenty years of hiding in this backwater town, pretending that he's here for the 'Good of a Small Town' for nothing. For twenty long years he had hid from Ben and Gwen because now he wanted nothing to do with them. If he saw Ben, his resolve that Ben was still doing the world some good would probably disappear. Even now, he was having a hard time controlling himself when the person who betrayed his father, and believed the impostor was sitting next to him.

"This is so cool!" Tessa squealed, "Daddy! You never told me you knew Gwendolyn!"

Gwendolyn looked back at Tessa and smiled.

Tessa grinned from ear to ear, "I'm a huge fan! Oh! And guess what? I have…"

"Theresa." Owen warned. She fell silent.

Finally, the car rolled into the driveway of their small home. Owen put the car into park, looking back at Kalvin in the rear-view mirror, "Kal, don't be like that. I promise you, soon I will start working twice as hard to be the perfect father. I will do my job, and your mother's as well."

"Yeah right." Kalvin pouted, hopping out of the car. He did not even bother to open the door. He started off down the road, shoving his hands in his pockets.

Owen watched him go and almost felt his heart break all over again. He sighed and picked up Kalvin's bag.

"Ignore Kal, Daddy." Tessa huffed, "He's just a dweeb." She grabbed Gwendolyn's hand happily, "Come on! I want to show you my room!"

Gwendolyn was instantly reminded of how she treated Ben when they were kids and had to smile. At least 'Dweeb' was better then 'Mega-Dweeb'.

Owen's home was small, or, at least small to her standards, a cozy little four bedroom home with a dinning room, kitchen, and living room. One of the rooms stood off of the living room.

"That's Daddy's office. We're not allowed in there." Tessa smiled, "My room is down the hall."

Owen waited until Gwendolyn and Tessa were away, before walking over to his office and unlocking the door. He stepped inside and closed the door behind him. There, inside the room, was Tena's Omnitrix. It had taken Owen a long time to remove it from her corpse, but it was worth it to make sure it did not fall into the wrong hands. He looked at it for a few seconds, as soon as he got it from her wrist, it had reverted to its first form, and probably its first settings.

Owen sighed. This was not right. It did not feel like a coincidence that the 'Mana-Tracking' Anodite just happened to be crossing the street near his home, only a week before Kenny's birthday? He gritted his teeth and shook his head. No, Aunt Gwen was never like that…it must just be a coincidence…

A scream outside his house caught his attention. He turned and bolted from the room, doubling back to lock the door, he crammed the key into his pocked…and failed to realize when it fell out. He knew that scream - that was Kalvin's scream!

He ran out the front door just as some kid threw Kalvin to the ground. The boy quickly kneed the larger man in the groin and rolled him off of him. Another boy punched him in the side of the head. Owen watched in terror as Kalvin hit the ground hard. The older boy was about to hit him again when Owen finally reached them, pulling the kids apart.

It took everything he had not to beat the living shit out of the boys, "What is this?"

"Mr. Tennyson!" The boy who punched Kalvin gasped, "Man! I'm out of here!"

He turned and bolted, his friend on the ground pushed himself up and ran as well. Owen bent down and looked at Kalvin's swelling cheek, "Are you alright?"

"Do I look alright?" Kalvin snapped,

"Kal…" Owen whispered, brushing his hair out of his face, "What happened?"

"I apparently looked at them funny." Kalvin rolled his eyes, pushing his father away from him, "But what do you care?"

"Kalvin." Owen repeated, but the boy just pushed him away again.

"If you cared, you'd let me try out for karate, or judo…or something! If you cared, you'd let me try out for sports or something!" Kalvin shouted, walking back into the house,

"Kal!" Owen sighed, "Those are all too dangerous…the thought of something happening too you…"

"Would be a relief." Kalvin muttered, dusting some of the dirt off of his shirt as he walked inside.

Just as Gwendolyn was walking outside, "Well…it looks like your having some problems…I should go."

Owen straightened up and looked at her in suspicion, "No. It's fine."

"No…I've got a mission on Zoroaster." Gwendolyn replied, "I was on my way to get some last minute supplies when I ran into you…so I should go."

Owen folded his arms, "Nice seeing you again."

"Don't say that so coldly." Gwendolyn rolled her eyes, "Goodbye…Owen."

She turned and strutted off back down the road. Owen waited until she was out of sight before walking back inside. He stopped in his tracks…the door to his office was open.

"Um…Daddy?" Tessa asked, folding her arms.

"Not now!" Owen snapped, he instantly regretted it with the look of pain that crossed her face. But now wasn't the time. He ran into his office and nearly felt his heart stop…

…the Omnitrix was gone.

"That thief!" Owen screamed.

~ * ~

"Mind dropping this garbage into the Null Void Chamber, Grandpa?" Ben asked, handing a Null Void Pod to an elderly man with a robotic arm.

The man nodded and walked off with the pod. Ben watched him go with a smile.

"It's our danger alert!" A boy with maroon hair, and dark skin said proudly, his hands on his hips, his friends watching him in awe. "A call comes in, and my Dad takes off to…you know, save the world."

Today, Kenny Tennyson turned ten years old, and to celebrate his first decade birthday, he finally convinced his father to let his friends come to their headquarters for a party. It had nearly taken him a year to get his father to cave. But it was worth it. He was proud of his father, and what his father did. He wanted his friends to know just how cool his Dad was.

"Wow!" A scaly hippopotamus-like alien gasped, "And my Dad's just a boring old dentist."

"And someday, I'll be right beside him!" Kenny said with a large grin, closing his eyes as he imagined it.

Ben felt pride well up inside him as he heard his son talk about him like that. It made this hero business just that much more bearable. He watched as a hologram of Gwendolyn appeared. He smiled and thanked any holy power that might be out there that she got that second Omnitrix for him to give to Kenny for his birthday. This year, he was going to make all Kenny's dreams come true.

"Aunt Gwendolyn!" Kenny gasped,

"Actually, your first doufus cousin, once removed." Ben smirked, walking up to her.

"Aren't you ever going to grow up?" Gwendolyn replied. "Sorry I'm missing the party. I'm still stuck here on Zoroaster, tracking down the red dragon from the Eight Pit of Novato."

Kenny looked downcast, Gwendolyn felt a pain in her chest. He really looked upset that she wasn't there. She held back her feelings as she opened a portal, hoping this would cheer him up, "But I got you this in the mean time." A clay puppy launched out of the portal, knocking Kenny over. Kenny laughed as it licked his face, and Gwendolyn disappeared.

Grandpa Max rolled in a cake, and everyone cheered, "HAPPY BIRTHDAY KENNY!"

And then it was time for presents. Ben waited patiently as Kenny opened everyone's gifts, and then finally, it was his turn.

"Now you know I haven't been to psyched on letting you into the hero business…" Ben said calmly,

"Really?" Kenny pouted, folding his arms, "I hadn't noticed."

"Fighting Aliens is not kids stuff Kenny." Ben stated. Grandpa Max coughed. Ben sighed and looked over at him, before continuing, "But…since I got the Omnitrix when I was your age," His voice sounded forced as he tried to cover up the lie, "I thought you should have this."

He held out a pod towards Kenny, and the boy hesitated before reaching up and grabbing the large metal sphere. It opened up to reveal an Omnitrix, and Kenny grinned in excitement before it jumped onto his wrist.

"Yes!" He smiled, "My own Omnitrix!"

~ * ~

"A-are you sure Dad?" A young black haired boy asked, as he stood in front of a hologram of his father from the Null Void,

"Yes son…I have a plan to get out of here…but I need your help." Kevin grinned darkly, "This is what I need you to do…"

Devlin listened to his father intently. He had missed him so much, and he wanted nothing more then to get his father free so he could be with him once more.

"Now go…and Devlin…don't fail me." Kevin growled,

"I won't Dad! You can count on me!" Devlin cheered.

~ * ~

Blind rage consumed Kevin, from the second he saw Ditto, all he wanted to do was rip its head off. He completely forgot about restraining himself, forgot who he was, or that Devlin was there. All he cared about was seeking revenge.

"Y-Your Kevin's son?" Ditto coughed.

"He's a real chip off the old block…isn't he…'Benji'." Kevin spat his old nickname for Ben as if it was acid. The rage grew until he no longer control it.

"That's not Ben! That's his son, Kenny!" Devlin corrected.

"Do you know what you've done?" Ditty gasped.

Devlin felt the guilt grow within him, "Dad…we'd better get out of here."

"Wait." Kevin said through his teeth, "Now what's the best way to take revenge on my good buddy Benji?" He rubbed his chin, looking down at Devlin, but barely even seeing the boy through a haze of red, "Hey, I know…TRASH HIS SON!"

A look of sheer terror crossed Ditto's face, and he backed up, "D-Devlin…you don't have to be a part of this. You made a mistake…ok! But you can fix it." The clay puppy ran out from behind Ditto and attacked Kevin.

The Aufnehman looked amused. He stomped down, barely using an ounce of his strength, and the clay puppy shattered. He moved too fast for Ditto to process, picking him up and holding him in the air as the Omnitrix timed out, turning him back into Kenny.

The sound of the Omnitrix timing out sparked something in Kevin's mind. Something almost came forth…a memory…some humanity…

"You're making this easy for me, aren't you." He grinned. He tightened his grip on the boy's shoulders. But the red haze was dimming. He started to see the boy a little more clearly, and he no longer wanted to kill him. Anger flared up again at his own weakness.

A beam hit him in the side, and Kevin went flying across the room, dropping Kenny to the ground. Kevin gritted his teeth against the anguish and looked up as Grandpa Max hit the alarm. Kevin moved with the speed of a Kineceleran, and grabbed the old man's robot arm, breaking it within his grasp.

He went forward to kill them both, but the urge to kill had dimmed. He bit his lip, "I have a better idea."

~ * ~

"Grandpa? Kenny?" XLR8 gasped as he zoomed into the Null Void Chamber.

Devlin jumped down from behind, disguised in his monster form. Ben quickly turned into Four Arms, "Not much of a trap. Was I supposed to think my family tied themselves up?"

"Oh Ben. You always were too smart for me. Or was that the other way around?" Kevin said, mostly as a pun reflecting on the fact that Kevin knew that this 'Ben' was an impostor. He knew it was a bad pun, but it was the first thing that came to his mind, and just the sight of the impostor sent his rage into the red again. The red haze was back, and the only thoughts crossing his mind were those with the need to kill Ben. The mere sight of him sent him into a frenzy.

He was in such a rage, he had no idea what happened for the rest of the fight. By the time he finally came too, he was back in the Null Void. He screamed out in rage and pounded his fist through the nearest rock formation.

Curse him! Curse that impostor! Curse his family! Curse anything that relates to him! Kevin screamed as loud as he could, destroying everything he could see. He was going to get his revenge…one way or another.


Sorry for the recap there, I thought it was necessary to show Kevin's side, and what the Impostor thought…after writing All I Have To Give…watching the Ken 10 and the Ben 10,000 episodes are a little hard now.

Too Many OC's? Don't worry. With what I have planned…without OC's…Devlin would be screwed.
