Hi guys! I'm a little embarrassed since this is my first fan fiction ever. Yeah...I know it's sad T^T. But I finally have the courage to officially post this, since Bwen have been driving me crazy lately! Maybe because Omniverse is not at all providing any Bwen moments (TT_TT). Like they're perfect for each other, but Man of Action just had to make them cousin so the plot could flow better! Originally Gwen was supposed to be a friend from Ben's class, however it wouldn't have made any sense why she would be traveling with Ben and his Grandpa for summer vacation. But I don't know... the whole cousin and taboo relationship thing creates a forbidden+psychological element = enrich plot and drama contents for me! I love writing about tragic heroes and their inevitable downfall! I also like to explore the psychological aspects of the human mind. This got me wondering what if in an AU Ben lost Gwen in "Ben 10:The Secret of the Omnitrix" how would he react after the battle was over and be confronted with Gwen's death? How is Ben's mental state in all this chaos? Anyways, enough with my rambling and onwards with the story!

P.S. In real life I'm all against incest considering I have siblings and no, it's just wrong. But this is a fandom so why can't I express my love for these two perfect couple? Also be warn there will be grammatical mistakes and OOCness! C:

His Life.

Prologue

On that day, 10 year old Benjamin Kirby Tennyson lost something crucial that made him change. Not something, rather someone… He lost his cousin Gwendolyn Tennyson all because of his selfishness. All due to his naïveté that nothing could possibly harm or pose a danger to his gallant self, seeing as everything that goes wrong (usually by his mess up) would somehow work itself in the end. He would come out untouched…superior in all his heroic glory!

This time it didn't.He lost her… lost Gwen all due to his foolishness.

Others would say he was pretty lucky, emerging out alive with the Omnitrix not blowing up in his face with half the galaxy in the process. Ben however, suffered a great loss. He never felt this… empty? Useless? Completely Defeated? How was he supposed to break it to his Grandpa? Sorry Grandpa, but Gwen die protecting stupid old me like always. Yeah… that would definitely go well! What is he supposed to do then? His thoughts were in a jumble mess now that the battle with Vilgax was over… Nothing to occupy his mind to the inevitable confrontation with death.

The death of his cousin was the only thing consuming his entire being. The overpowering factor that was overriding him with great anguish and torture.

Gwen…Gwen…Gwen! Both of his hands turned into pale fists as his eyelids squeezed tightly. He was trying his hardest to push down the anger, frustration and pain. It was excruciating! There was this dark inkiness swirling in his mind, making him fall… deeper into the depth of insanity.

Because all of this was his fault.

"Gluto!" Ben heard Tetrax yelled in surprise.

Ben's head whiplashed in delight because if that snot wasn't dead maybe…just maybe Gwen was…

He knew he shouldn't be too hopeful or it would crush him harder than witnessing Gwen being taken against his will because he was useless to stop it.

What sort of hero was he when he couldn't save her? Her of all people!

Then an idea struck him.

Just maybe the universe had enough of harassing him—making this into a huge joke so that he would be taught another lesson… she would then jump out of nowhere to surprise him! That must be it! Gwen would appear in front of him announcing to the whole universe she was alive! Alive and together with him! Everything would be right again!

However, the ideal hope, fantasies—delusions, which he had stunning elude himself into believing were astounding vaporized, because he saw just… Gluto.

No, he won't believe she's gone. His eyes were just tricking him. They must be lying to him! He was going to end this sick joke—nightmare immediately!

"Gluto!" He shoved Tetrax out of the way practically slamming into the Protost. "Gwen! Where is Gwen?!" His emerald eyes were large and frantic as he shook the blob like creature in a crazed daze.

The alien called Gluto only shook its head in sadness. The alien didn't even meet his eyes! Ben's body tremble as he hugged himself losing all form of motor control as he swayed back and forth. He didn't know what was becoming of him. Losing Gwen, accepting her death… felt so impossible!But for some peculiar reason he started laughing. He couldn't stop! What a terrible joke Gwen was playing on him!

His world wasn't crumbling! He will not allow it to! She wasn't dead!The universe would crash and burn if she was. He'll make sure of it.

Ben's laugher was bursting with a malice like cruelty, every second his pitch increasingly twisted to a level of insanity. Sounding more sinister than any monster and villain combined. It was a laugh consumed with utter madness.

Without his knowledge the Aliens surrounding Ben started to instinctively step back. They knew that his cousin's death brought a huge emotional impact on the young earthling. Humans tend to develop an unconditional affection to certain others of their kind after a prolong period of social interactions, thus forming certain degrees of affection in each relationship. In rare cases, high level of affection brings about undesirable results. This aspect was the only special characteristics that made humans unique from other life forms. However, they never expected for the boy to react like this.

They didn't understand his psychological state. In this way fear creeps in. Their instincts told them he was dangerous, an uncontrollable variable. Making this the very first time they truly felt fear from the small boy. A human youth who is the weakest of all species in the universe and the weakest of his kind. But, aliens as strong as Tetrax who has faced unimaginable dangers, believed this moment to be the most dangerous. Certainly they were in peril when faced with an unstable boy, holding the most dangerous weapon of the universe at his disposal. If they don't do anything soon and fast… Things could go bad to catastrophic! The universe may suffer more than half the galaxy being destroy…

"G-G-wen a-ali-ve." Gluto announced suddenly too scared that if he doesn't tell the boy, he could be confronted with another threat.

At that moment everything became extremely silent. The laugher stopped. Everything froze as if time clogged in its function.

"What?! Tell me now." Ben had an expression of absolute calm glaring the blob down. He would not raise his hope this time. He learned his lesson.

Everyone noticed Ben's sudden change in demeanor. Even to them, not fully understanding the human emotions knew it was strange how the boy could change his emotions so effortlessly. From deranged madness to eerily calm.

A person shouldn't be able to alter their mental state like a switch so easily, Azmuth noted but doesn't say. This boy who was possessing his greatest of creations had pipe his interest in the shortest amount of time as he battles his antagonists both physically and mentally. Disregarding the dangers to himself and the rest of the universe, only diving between madness and his own sanity or what is left of it... Azmuth mused.

Azmuth recognizes the Omnitrix being in the wrong hands could be disastrous, especially in this boy's disposition. This could be the greatest evil he had intentionally created, but at the same time be an evolutionary leap for the entire universe! Oh, the purpose! He could stop this now. End it all and take back the Omnitrix. However, knowing how insignificant he cared for the universe compared to his curiosity, it was barely a hard decision to dissect. He would leave his device with the boy. He was quite intrigue with the outcome.

"G-Gwen ca-st a ssp-ell and th-en hu-ge diss-ruptio-n hap-pen-ed dis-s-app-ear-ing into-o a bblue por-tal bee-fore I cc-ould ssa-ave h-err." Gluto told the group while being super aware of the emerald eyes piercing into him like daggers.

"Gwen… is alive." The boy whispered to himself in a tone the aliens around him couldn't comprehend. His eyes became a brighter green than the darker shade he was emitting previously.

"What are we waiting for? Guys lets go find her!" Ben's voice spoke in a cheerful manner entirely different from his cold exterior earlier. His whole demeanor brightening.

"Boy, I don't think she's that easy to locate now that we know she was transported somewhere in the universe!" Myaxx finally spoke judging it was safe.

However, she quickly regretted it. The boy was pressuring her to say that again. Daring her to unleash his fury. Well, she will! She had enough of his tantrum. Anyways, she was only stating the obvious, completely disregarding her earlier fear of the boy. She was a species more superior to his kind so it took her a moment to surpass the fear because she couldn't comprehend her concept of fear.

"Now, now don't need to fight amongst ourselves when this problem could easily be solve with one of my inventions." Azmuth announced, ignoring the tense pressure emitting from the two as he took out a small circular device. He then threw it up and all of a sudden the group was entrapped by a massive virtual map containing the whole universe. Ben was more annoyed to be amazed.

"Let's see… Huh, this is certainly extraordinary." The creator of the Omnitrix questioned in curiosity. Usually nothing should surprise him anymore.

"Well, what?! Come on!" The human shouted in irritation.

"Seems like she doesn't exist in this universe."

"What." Ben's voice took on a darker tone. "Then where the hell is she?" His tone a clear demand.

"Ben I think you should mind your manners to the creator of the Omnitrix. I don't think it will help you in your quest to finding your cousin." Tetrax tried to provide a piece of advice from his past experiences. It won't do yourself any good to be giving attitude to others helping you. He knows, because in his case it always ended badly.

"If he is useful, then I will." Ben spoke condescendingly.

"Azmuth let's go! I have enough of this boy's childish tantrum!" Myaxx shouted in frustration.

"Boy, if I wasn't curious in nature I would have forsaken you by now. What I stated was that she wasn't in this universe. Now do you apprehend what I'm getting at?" The Galvan spoke with absolute authority.

"Then what other universes is she on?!" The boy uncrossed his arms and flung them in the air. It was clear to Azmuth that the boy evidently did not comprehend the nature of the situation. Neither did the other aliens, except Myaxx.

"Azmuth! Don't tell me the human girl was involved in a dimensional wormhole?! That's fundamentally impossible with her current situation! Not to mention her body mass and the pressure it would place on her physique…plus—" Myaxx cut herself off noticing the boy's fury just on the edge of erupting. It was not good to be talking about the human girl's survival rate in front of the miniature, unstable monster in front of her.

"I think it would be better to explain it in a way we could all understand." Tetrax quickly inputted. Myaxx inwardly thanked him.

"Right now what I need is for everyone to remain silent. I'm currently searching the other dimensions." Azmuth commanded. Feeling annoyed for the first time in a long time. How he wished he could be left alone to fully be absorb with his inventions.

"Other dimensions…?" Ben said hollowly.

"Why bother? The human girl wouldn't be able to survive—" Myaxx stopped herself. It's better just to stay quiet as she saw the demon green eyes' death glare.

"This won't work. There are too many numerous dimensions out there... even alternative ones. This device doesn't contain that much information on those cosmos. Even if by a miracle I find her…there are also the laws of intersecting parallel universes or crossing to one… as well as the necessary procedures and technologies to even manage dimensional transport... There are too many unknowns." Azmuth stopped himself and stared at the boy.

"Boy, you must know—" The Galvan started, preparing to enlighten the boy on dimensional travel and their theories before he was interrupted.

"It doesn't matter how long it takes or whatever I have to do. I will find her." Ben stated with new found resolution. It doesn't matter as long as there was a chance that Gwen might have survived!

Azmuth nodded in approval of his answer. Myaxx only sighed in frustration, but didn't argue against it. By this point she knew the outcome, knowing it would be fruitless to argue. But, Tetrax disagreed.

"Ben… What about your grandfather? Shouldn't you return to Earth and—" Tetrax reasoned, but was interrupted with a firm, "No. I'll return to Earth with Gwen."

Tetrax was downcast. What was he going to do when he reports this to Max? Knowing the Plumber… Max would no doubt take actions, knowing full well of the threats his grandchildren were submerging into alone. The great universe was far too dangerous for two human 10 year old to travel. He had to somehow convince Ben to return home. Bringing one back was better than none. Tetrax never experienced Max's wrath. From what he heard, it wasn't pretty…

"Tetrax don't worry dude! Tell my Grandpa I'll have my cousin back before dinner!" Ben tried to lighten up the mood. Even he knew this would take a while and he didn't want to waste a second more if he can discover her sooner. He knew if he were to return home, he would never be given a chance like this again! He would be confronted with reality; a funeral, then enforced under house arrest while involuntary be forced into normalcy with his Omnitrix banded, never to battle aliens again. But, eventually he will have to accept her death. Then his most unwanted fear of forgetting her would crawl under his skin like a parasite, spreading like a cancer! The person who sacrifice herself for him and he goes off living his life! To others they would have taken it, captivated to take the easy way out. But he won't.

Ben closes his eyes, his resolve firmly set in stone. It's better searching for her his entire life than forgetting her! It's worth sacrificing his whole life for her. After all, he was only repaying his debt; it was her life that saved his. Now he has to return the favour.

His life, for her life.

Thanks for reading the prologue if you ever got this far...I would like to thanks everyone for reading my first fan fiction :)
