Planet Earth, this world is home to the Z-Fighters. This world has experienced a lot of threats that wished to destroy it, the Saiyans, Frieza, Cell, Majin Buu, and many more; but the Z-Fighters have managed to overcome those foes. Currently, Earth is at a time of peace; most people have been relaxing during this time of peace while there are still some people who continued to train even during a time of peace. But peace is something that never lasts.

Somewhere by a lake, energy began to build up until a bright light appeared until taking shape of a person; slowly the light began to die down which displayed the features of that person, that person was the Saiytonian hero Y/N. The hybrid looked up at the blue sky seeing the beauty of the land around him, he was amazed by it.

Y/N: "Finally, I'm out of that wretched place." Y/N took a breath of the fresh air and sighed in content. "Too bad I can't enjoy it... Really sad though, the only entertainment I ever had was the books I read and the training. Well time to get going." He spoke in a nonchalant manner.

Y/N began to float upwards as he took off into the sky trying to find the Saiyan called Goku, luckily he learned how to sense energy otherwise it would be like finding a needle in a haystack. He sensed a lot of incredible energy signatures, so he flew to the closest one. He saw a city to which he looked at it with curiosity but he kept flying until he made it to a building that said, Capsule Corp.

He sensed some strong power levels behind the building, so he quickly lands in front of the building but before he thought of going to the back of the building, he looked up towards the sky again feeling so much warmth from the sun. He closed his eyes in bliss from a wonderful feeling from the sun on his skin, it was like he could feel a new surge of energy within him.

Y/N: "That feeling, that's the sun I presume... Thankfully I had a book about it, It's pretty, love the color." He admired the star that shines it's light down upon the planet Earth, the hybrid admired the planet's beauty. "It's a shame my universe never survived, I wonder what the Earth would be like in my universe?"

Y/N pondered on the thought for a bit until he was shaken from his thoughts as his mind was back on the matter at hand. He looked towards the Capsule Corp building and his facial expression changed from a curious expression to a serious one.

Y/N: "I sense multiple power levels behind this building, I noticed that a few of them are pretty high." Y/N spoke with a serious tone as well. "I hope that Saiyan is here otherwise this was a waste of my time."

Slowly he floats up in the air as he went behind the building to see a group of people sitting at tables talking amongst each other. But quickly a couple of people spot him to which he immediately lands on the ground to see everyone look at him with confusion.

???: "Who are you?!"

One of them demanded the hybrid to speak, this causes him to hold his hands up showing that he wasn't a threat.

Y/N: "Don't worry I'm not a threat." He spoke followed by a light chuckle. "I'm here on a mission actually."

One of the males who had spiky hair stood up and walked over to Y/N to get a good look at him, the hybrid just had a calm expression. That's when he spoke up to the hybrid.

Spiky Haired Man: "Man, am I sensing some crazy power from you." He chuckled lightly.

Y/N: "I can sense some strong power from a couple of people here, where are my manners my name is F/N L/N."

Goku: "Nice to meet you, my name is Son Goku." He smiled.

That's when another person shorter than Goku walked over to Y/N and saw he had a tail, Y/N's tail was wrapped around his waist.

Short Man: "Kakarot! You idiot, this boy is clearly another Saiyan." He scoffed after speaking.

Goku: "Yeah, you're right Vegeta. How come I didn't notice it right away?" He scratched the top of his head while softly chuckling.

Y/N: "Uh... I'm not fully a Saiyan. One time I heard the old man say I was a mix of a Saiyan and Kryptonian, he dubbed it a Saiytonian."

Vegeta: "Never heard anything about a race called Kryptonians, none the less it why are you here? Clearly, you're not here to settle down on Earth." He glares at Y/N while crossing her arms.

Y/N: Um... Right! Sorry for not stating the reason why I'm here... I'm here because I need training, you see the Omniverse is in danger, I'm not from this universe as you see my universe was erased without a trace left..." Y/N clenched his fists, his body started to tense up. "My... Real family is gone..." The hybrid couldn't finish as a tear dropped to the ground.

Goku: "Wow... I'm sorry to hear that Y/N, of course, you're welcomed to train with us!"

The people sitting at the table walked over to join in the conversation.

Bulma: "Sorry to hear about your universe. My name is Bulma."

???: "How do we know you're telling the truth? For all we know you could be saying that to get us to let our defenses down so you can slaughter us!" A pig-like person spoke with worry in his voice.

That's when Bulma smacked the pigman on the back of his head, this caused him to hold the spot where she hit him while groaning in pain.

Bulma: "You can't just assume everyone is a villain just by looking at them Oolong!"

Y/N: "I'm not planning to kill anyone here, I just need to get stronger and I'll leave you all alone." Y/N said with sorrow. "I give you my word I'm not here to harm anyone."

Y/N was confused about there being a talking pig, but he didn't want to continue that thought as he was more focused on getting stronger.

Goku: "Do you want to start training now? I know a perfect spot to train."

Vegeta: "Hold on Kakarot, I know you're going to train with him so you can one-up me! No way! I'm training with you two!" Vegeta shouted.

Goku: "Okay Vegeta, we'll both train with him. I wanted to see how strong he is for myself." He scratched his head once more while chuckling.

Y/N: "Umm... Okay..." He looked at both Saiyans with confusion.

Bulma: "You'll get used to it." She smiled at Y/N.

Y/N: "Umm... Alright... So quick question, where is this training place?" He had a confused expression once more.

Goku: "You'll see, grab onto my back."

Goku places his index and middle fingers on his forehead, Y/N puts his hand on Goku's back while Vegeta reluctantly puts his hand also on Goku's back. Then in an instant, Goku, Vegeta, and Y/N all vanished without a trace left.

Oolong: "This whole universe thing is getting confusing."

Bulma: "Strange though that something powerful like that is coming to destroy us, but what Y/N is saying is true then we have a huge problem coming." She thought about the situation.

Meanwhile...

Goku, Y/N, and Vegeta all appeared at the place called the lookout, Y/N looked around the area with utter confusion until he was approached by an alien that is called a Namekian.

Dende: "Hello, you must've been that large power level that just arrived. My name is Dende, I am the current guardian of Earth." He smiled at Y/N knowing he had no ill intentions.

Y/N: "Hello Dende, my name is Y/N. I come here to receive training from Goku and Vegeta, they've agreed to train me." Y/N greeted. "You see the Omniverse is in grave danger, I've lost my universe due to this situation and I've been living outside of the Omniverse. I've trained in a realm that has gravity more intense than the gravity here all my life, but yet I'm still not strong enough." He sighed.

???: "Oh dear, that does sound serious."

Dende: "That does sound serious, Mr. Popo, and I need to discuss something can you wait here a moment." He and Mr. Popo walked away.

Goku: "This is only a pitstop, I have to get something you may need in your journey." Goku flew away from the three as he flew down the lookout.

Y/N: "Umm... Alright... So... Vegeta, tell me where is this special training spot?" He crossed his arms while speaking in a very confused tone.

Vegeta: "Kakarot and I trained on a planet that is home to the God of Destruction Lord Beerus. We both achieved Super Saiyan Blue while we were training with Whis, I'm sure that's the place Kakarot is talking about." Vegeta also crossed his arms.

Y/N: "What's Super Saiyan Blue?" Y/N's right eyebrow rose, he tried to understand what was this Super Saiyan Blue.

Vegeta: "Super Saiyan Blue is a form that combines the power of a Super Saiyan God and the Super Saiyan form. I assume you don't even know how to transform into a Super Saiyan." Vegeta closed both his eyes.

Suddenly Vegeta's energy began to rise at a rapid rate, Y/N's eyes widen with shock as he sensed the huge power level. The floor beneath them began to shake, Vegeta's hair flickered from blond to his normal hair color multiple times. With an explosion of energy, Vegeta's aura erupted as he yelled out, his hair color changed to blond and his eyes were now emerald green.

Y/N's was frozen in place, he was simply bewildered by this display of power; the moment he sensed Vegeta's energy, it was greater than before.

Y/N: "This power... This is what you call a Super Saiyan?!" His voice was shaky as he was taken aback by this.

Vegeta: "This isn't the only state a Super Saiyan can achieve, you can go beyond this form." Vegeta smirked. He reverts back to his normal state as he crossed his arms. "But for now, you'll have to learn how to reach this state before you can even think about going beyond Super Saiyan. You can achieve this form, even if you aren't a full Saiyan."

Y/N: "Man... The fact that I've never even reached that level of power just shows my training wasn't enough..." Y/N's head hung low as he had a sense of dissatisfaction.

Vegeta: "Grrgh, if you're going to doubt yourself, maybe you aren't ready to protect the Omniverse! You have Saiyan blood in you, show some pride!"

Goku flew back up and lands close to Vegeta and Y/N, he had a mysterious bag in his hand. He looks over to see Y/N was in a gloomy state while Vegeta had an angry look on his face.

Goku: "Vegeta, what happened? Also, why did you power up?" Goku had a look of confusion on his face.

Vegeta: "Because Kakarot, this boy didn't even know about a Super Saiyan. He has Saiyan blood in him but he acts like what he did doesn't matter, us Saiyans always break our limits, but he thinks he wasted his time training." Vegeta glares at Goku.

Goku: "I understand Vegeta, but he is still learning. Once we head to Beerus' world, Whis will help us train him if we get him and Beerus something tasty to eat."

Y/N: "Honestly, it's okay. That's why I'm here... I'm here to get stronger." Y/N's posture was normal again.

Goku then tosses Y/N a bag that was full, the hybrid caught the bag with his right hand. He did not know what was in that bag.

Goku: "This is for you when you leave, you're going to need it." He smiled for a brief moment. "Now everyone, once again grab onto me. Whis might be here again soon so we have to get there quickly." Goku places his index and middle fingers on his forehead once more.

Everyone once again grabs onto Goku and they all are instantly transported to Capsule Corp again, they made just in time as a new person was there that Y/N didn't recognize. Well, he didn't really get a chance to meet everyone there, but he was curious as to why he can't sense that person's energy.

Goku: "We made it!" Goku shouted excitedly. "Hey Whis!"

Goku and Vegeta flew over to the angel Whis, the angel looked at both of them with a smile.

Whis: "Ah, Goku and Vegeta, have you two been keeping up with your training?" He questioned the two.

Vegeta: "Don't know about this clown, but I've definitely been keeping up with my training." He said pridefully.

Goku: "I have been keeping up with it as well, hey me and Vegeta were wondering if we can train on Lord Beerus' planet."

Whis: "Well, we could but you know how Beerus gets when he doesn't get something delicious in return."

Y/N just looked at the angel with the same confused look as he did when he saw Bulma, he's never seen an angel or a woman. Whis did take notice of Y/N to which he flew over to him, his left hand was behind his back while he carried his staff with his right hand.

Whis: "Odd, you have a Saiyan tail but your energy is different from a normal Saiyan, it's not God ki but it's something I've never seen before." He examined Y/N.

Y/N: "Actually, I'm not from this universe. My universe was destroyed a long time ago, that may be the reason as to why you say that. My name is Y/N, I'm not fully a Saiyan, I'm also part Kryptonian. You see Whis, I'm on a critical mission as everything here is at stake." He politely said.

Whis: "Everything you say? This does sound rather serious, I should inform Lord Beerus about this." Whis had a look of concern.

Y/N: "Is this Lord Beerus guy gonna let us train on his world?" He had one eyebrow raised.

Whis: "Under normal circumstances, he'd be pretty grumpy if we disturbed him without any delicious cuisines to give him. I did come here for a delectable treat, tell me, who sent you here, Y/N?" He questioned the hybrid.

Y/N: "He never told me his name, but he is the current guardian of the Omniverse."

Whis: "Oh dear, so you come from outside of the Omniverse, so that means he's grown weak."

Goku: "How do you know this Whis?" Goku looked in confusion.

Whis: "Before you were born there were multiple guardians protecting a designated Omniverse, an Omniverse is a container of everything that exists. Each Omniverse is given a guardian to protect it from threats that wish to destroy it, the guardian of our Omniverse, had given Grand Zeno a visit. He had informed Grand Zeno that the guardians were killed from a being of unfathomable power." He points to Y/N. "He said that he is growing weaker, soon he wouldn't be able to defend the Multi-Omniverse, he had given this position to this young hybrid here. Y/N is the now the new guardian of the Multi-Omniverse."

Goku: "No way! You mean that Y/N is gonna be the next guardian, that's mean that old dude saw some serious potential in him." Goku was a little bit excited.

Vegeta: "So you're telling me this boy is gonna be even more powerful than the Omni-King himself?!"

Whis: "Precisely Vegeta, once his training is over, I assume the guardian will bestow his power onto Y/N. Meaning that you'll be given a big responsibility Y/N."

Y/N: "I got some really big shoes to fill then huh?" Y/N had a nervous tone in his voice.
