AN: Hey everyone, I have a new short story here. So, a bit of context for this crossover. Years ago, I have a crossover between DBZ and RWBY called Just Saiyan. I was simple Yang going though the Z sagas, being trained by different DBZ characters, and learning some cool moves along the way. My intention was to work with that story though all of Z and even Super, but I got writers block on chapter forty and stopped the series. Looking back, it was not one of my better works with a lot of flaws. And unlike Color Theory, I have no intention of reposting it. However, I thought of doing a somewhat spiritual successor in this story. My favorite part of Just Saiyan was having a non-DBZ character learning the moves, so I thought I could expand on it here. This won't be a long story either, maybe only 10 to 15 chapters if even. Also, I am not taking power levels that seriously here (i.e. putting a number to it), but there is a noticeable gap in strength between the series. The tone is also a bit more comedic here, poking fun at both series for this fact. As far as timeline stuff goes here, assume that end of Super timing matched with the last arc of Volume two. That's all I will set up with for this story before chapter one begins. Hope you enjoy this chapter, leave a review with your comments and questions, and have a nice day.

Trained By Saiyans

Chapter 1 – Arrival

Clashing at supersonic speed, Goku and Vegeta sparred over a resort island. Down below, Bulma watched from a lounge chair as she cradled Bulla. Nearby at a table were Whis and Beerus, who shared in a massive chocolate parfait, their eyes glowing at the tastes.

The two saiyans pushed each back before charging, "Ka-me-ha-me-," Goku said as he placed his wrist against each other, blue energy starting to gather.

"Galick Gun," Vegeta said as he pulled his arms back, his body shrouded in a purple aura, "FIRE!" The prince of all saiyans announced as he unleashed his attack.

"HA!" the Saiyan from Earth responded as he unleashed a blue blast. The two beams clashed, illuminating the sky with a mixture of colors.

The shockwave of Ki reached all the way down to the island. The blue haired scientist's chair shook as her daughter cried. The as the God of Destruction was about to enjoy the last bite of the treat, the table wobbled, causing the parfait dish to fall over on the ground, "That's it!" Bulma and Beerus said at the same time before looking at the sky, "Both of you, get down here!" They ordered as Goku and Vegeta had a look of confusion.

The two Saiyans descended as Goku say the food on the floor, "Oops." He said before scratching the back of his head with his right hand, "Sorry about that." The Saiyan from Earth chuckled as Vegeta tried to calm Bulla's cries.

"Will you two ever stop training?" Beerus said as he placed his hands behind his back.

"They are Saiyans, Lord Beerus," Whis said with a smile, some sassy in his tone, "Doing so would be against their nature."

"Still, this is getting ridiculous." Bulma said as she crossed her arms, glaring back at Whis, "Aren't you supposed to be training them?"

"For the moment, I am letting them figure some things out on their own." Whis said before having an idea, "However, maybe it's time for them to do the teaching." The attendant to Beerus said while Goku and Vegeta had a look of confusion. Whis spawned his staff, showing a holographic image of a planet with a shattered moon, "Lord Beerus is meant to destroy this planet, as most of its inhabitants are mindless beasts of destruction created from negative emotions." He said before showing a black furred, bipedal wolf monster with bone armor.

"Wow." Goku said awe, "Are they strong?" He said before the second thought came to his head, "Are they tasty?"

"Let's just say you would have to eat one quickly after killing it," Whis said with a grin, "The more civilized race has been fighting them for a long time. They developed weapons to fight, as well as some interesting abilities." He then looked to Goku and Vegeta, "However, it may help to have you two go to this planet."

"You want to send two Saiyans to liberate a planet of evil?" Vegeta responded as he rocked Bulla in his arms, "That would also be going against Saiyan nature, mine especially."

"I don't want you to do their job for them." Whis responded, "I think it would help if you two trained a few fighters. That's all." He said before looking back at Beerus, "This can tell us if they will be able to retain your teachings." He then looked to Bulma, "And it will force them the to hold back a bit more in practice." Both smiled at Whis' suggestion.

"Excuse me," Vegeta said in slight anger, "Don't we get a say in this?"

"No!" Beerus and Bulma said at the same time. Vegeta did not respond, not knowing which one he feared more at that moment.

"Come on, Vegeta, this sounds fun," Goku responded. Bulla cheering with a smile, causing the prince of all saiyans to sigh. The Saiyan from Earth then looked to Whis, "So, what's this planet called?" He asked with Beerus attendant smirking.

One Whis fast travel later.

The group landed in the middle of a forest with only red leaves. Goku looked around in awe as Vegeta gave Bulla back to his wife, "Huh, must be autumn in this region on the planet." Bulma commented as she looked around. Suddenly, she saw a large monster resembling a black bear with bone spiked back. She took a step back as the creature snarled.

Beerus then looked at the monster, seeing it roar at the God of Destruction, "I'm remembering why I put this planet on my destroy list." Beerus said as he took his right hand from behind his back and pointed at the monster with his index finger. A small purple beam of energy shot of out his finger, connecting with the monster's chest. Abruptly, the monster exploded, the blast taking out four nearby trees. He then turned to his attendee, "What did you say those things were called again."

"Grimm," Whis responded, "Their level of power rangers with each classification of the type." He then turned to Goku and Vegeta, "But none are even close to your level."

"Well, I hope to find some strong students then," Goku said before stretched his shoulders. They then looked around before focusing to the northeast, "I can sense some decent energy in that direction."

"If I remember right, that is towards an academy to train warriors." Whis said with a smile, "Though on this planet, they are referred to as Huntsmen and Huntresses."

"Wait, a school?" Goku responded in slight disarray, "I don't have to teach in one of those lecture halls like Gohan does, do I?" he said before slouching, "And I don't own any coat with elbow pads."

"You don't have to worry. You'll just ask the headmaster if he can let us train a few of his students." Whis said with the Saiyan from Earth before looking to the rest of the group, "I will be watching how Goku preforms. Lord Beerus, keep an eye on Vegeta." He then focused on the blue-haired scientist with a baby, "And Bulma, keep an eye on everyone." Whis said with Bulla, making a cheerful cry.

Whis and Goku began to ascend as the Saiyan from Earth turned back to wave, "Good luck Vegeta." He called, but the prince of all saiyans did not respond, only crossing his arms.

Beerus then walked over to Vegeta, "Well, he is going to have a slight advantage with his students. Seeing as how they are already at a school."

"But they will have the disadvantage of having Kakarot as their mentor." Vegeta responded before smirking, "I am confident my student will surpass whoever he teaches." He said before pointing southwest, "While he was looking for a group, I noticed the power of an individual not too far from here."

"Very well, lead to way," Beerus responded before he and Vegeta began to ascend. Bulma reached into her back pocket, taking out a capsule with a button on top. She tossed it to the ground, cause a smoke cloud to appear. An airship now stood in front of her. She took to the piolet seat after making Bulla was safely secured inside, then took off to follow the two guys.

Meanwhile.

In his head office, Ozpin filled out some paperwork as he sipped from a mug of coffee. Suddenly, he felt a tapping on the glass window behind him. In turning around, he discovered it was Goku doing the tapping, "Hey," the Saiyan from Earth said with a smile, "Can I train some students?"

Ozpin had a look of utter confusion all over his face, "…Sure." He said, assuming this was a hallucination.

"Thanks!" Goku responded before placing his right index and middle finger on his forehead, the popped out of existence. Ozpin started for a second at the empty window before turning his chair back around. He then looked at the coffee mug, wondering if it wasn't filled with coffee after all.

Back on the ground, the members of the Team RWBY walked down the airship landing section, their leader carrying an absurdly overpacked backpack, "Are you sure about this mission?" Weiss asked her leader, "What if we get some weirdo professor?"

"Come on, lighten up," Ruby responded, "I mean, the worst we could get would be Port or Oobleck."

Suddenly, Goku popped right in front of the four girls, "Hi," the Saiyan from earth said as Team RWBY eyes widened in astonishment, "My name's Goku, and I'm gonna be training you four."

"Ahh?" Blake said is confusion, pointing at Goku, "Did you just teleport?"

"Well, it's instant transmission." Goku responded before shrugging, "But yeah." He then turned to see a landing airship, "Oh, I think we can use that to go somewhere better for training." Goku said before boarding the airship.

"Was that his semblance?" Yang inquired to her friends.

"Or his aura?" Blake theorized.

"Maybe it was a new type of dust?" Weiss asked.

"…Is he an alien?" Ruby said with the rest of her team looking at her with skepticism, "Sorry…"

Weiss sighed before walking towards the airship, "Whichever it is, we did get a weirdo after all." She said before the rest of the team followed, each getting on the airship before taking off.

Meanwhile.

At a White Fang hideout, a few grunts were moving crates of supplies when one looked up at the sky. Their eyes widened behind their masks as Vegeta and Beerus hooved to the ground, "Now, which one were you thinking of training?" The God of Destruction said as before the White Fang grunts aimed their rifles at the two newcomers.

"These are all foot soldiers. Only low-level warriors." Vegeta responded with Beerus smirking. Suddenly, the two watched as the White Fang group break into two groups, allowing Adam to approach towards the guests, "This is the one I was sensing."

"Hmmm, compared to the rest, he does feel a bit different," Beerus commented.

"Who are you two?" Adam asked in an unpleased voice, then focused on Vegeta, "You look to be a human." He said before looking at Beerus, "And I have never met a faunus with your…condition."

"I am not human," Vegeta said with a glare, "Making that assumptions would normally cause me to kill you. However, I was going to-" The prince of all saiyans was going to ask until Beerus cut him off.

"Vegeta, what did this man just call me?" Beerus said as his eyes focused on White Fang Leader, "I don't like his tone. We should find someone else more…tame?"

"What did you just say to me!?" Adam said as he drew his red sword, but Beerus remained unimpressed. The God of Destruction's gaze remaining cold and unwavering as the White Fang Leader gritted his teeth, "You dare mock me!" Adam declared before rushing forward, attempting a downward vertical slash.

However, Beerus stopped the red sword with his left pointer and middle finger. Adam gasped as he realized he could not move his blade from his opponent's grip. Suddenly, Beerus glowed with a purple aura, "You raise a weapon against a God of Destruction?" Beerus said as he held his right palm in front of Adam's face, "Hakai." The God of Destruction declared.

Suddenly, Adam's body began to disintegrate into atoms, "AAAAAAAAAAHHH-!" he screamed until his head was gone with the rest of him. All that remained was the red sword, which Beerus pocked with his right index finger, turning it into dust.

The other White Fang members slowly back up in fear, while Vegeta remained unfazed by the last events, "Now, what I was trying to say was-" The prince of all Saiyans was then cut off again as all the grunts screamed in panic. Each ran away from the two who had killed their leader. Within seconds, only Vegeta and Beerus remained at the abandoned camp, "…I scene another above-average power level not too far from here."

"Let's go then," Beerus said as the two ascended, "And hope that this individual is more reasonable." The God of Destruction commented as Vegeta sighed. The two passed Bulma in her airship, who was upset she did not get to meet anyone down there.

AN: There you go, a short prologue to set up for the training in next chapter. As well as the reveal of who will be Vegeta's student here. These chapters will be a little shorter than my average at times, many because I am trying to take it easy this time around writing. Team RWBY is in for some cool stuff in the next chapter that I hope you stick around to read. That is all for now, thanks for reading, and hope to see you in the next chapter.
