Fire and lightning, thundering around the planet Onin had relocated to after stepping down from the time patrol. Screaming at the top of his lungs he managed to activate Super Saiyan Three after years of being unable to after the fight with Dabura, he moved to this planet because he wanted to learn to control his Saiyan power, being one of the strongest when he tapped into his hidden potential he wanted to capitalise on it. Flying as fast as he could around the planet had become a staple of his training however this time something fishy was going on. A strange blue rift seeming divine in nature opened in front of him absorbing him into it, flying at such a high speed made it hard to concentrate on the ground so Onin was surprised when he slammed head first into a tree taking it down, then another one and another before he finally stopped.

SEVERAL HOURS LATER.

Onin jumped awake on his feet sniffing at the air he could smell, smoke and blood, he burst off flying the way of the smell, he saw the cause of the unpleasant smell a burning town, he saw several ruff looking men some of which were bearing bloody weapons, the sight angered Onin, using Instant Transmission he moved to the men who weren't in direct eyesight of another and gave a swift blow to the head, he was about to strike one when he felt his hand get caught the perpetrator looking at him simply smirked "Naughty, Naughty using such a potent strategy against buffoons, luckily for me I practice Ki as well." Launching Onin with a roundhouse kick to the gut the mysterious fighter flew after him and placed his hands in a well-practiced position "GALICK GUN…" pushing the energy build up forwards towards Onin "FIRE!" he screamed which was met with a purple energy beam hurtling towards Onin who quickly placed his hands in front of him "Kamehameha!" he shouted as he turned around and used the blue beam to propel himself out harm's way he then looked at the mysterious fighter "who are you?" he asked panting the mysterious figure started laughing
"You'll figure it out eventually, short story short I've been sent here to make sure you are as strong as you'll need to be, but now I'm getting excited!" the figure started screaming and lit up in golden rays.

On the ground Chrom with the help of Frederick, Lissa and his new tactician Robin had finished what little bandits had been in the town he was congratulated Robin when Lissa tapped him on the shoulder her mouth agape she muttered "Chrom… Chrom…" over and over until Chrom looked at her and asked her what she wanted she just pointed upwards and said "Look" Chrom did and what he saw utterly scared him,

In the sky were two people fighting.

Onin dodged several rapid punches from the Mysterious Fighter, seizing the moment of distraction Onin sped behind him grabbed the Fighter's arm and threw him at the ground, he proceeded to hurry to the ground where he charged a Ki wave which he fired at the fighter blasting him skywards while also dealing damage to the Mysterious Fighter who responded to this by using Instant Transmission to get back to Onin and attack him which he fired several larger Ki blasts, the burning heat on Onin's back almost made him go unconscious but he fought back the pain and started to centre his Ki and with a shout of "KAIO-KEN" he covered himself in the bright red aura.
Chrom shocked and in disbelief just had his mouth wide open trying to keep up with these fighters yielded nothing but a sore head he had seen nothing like this, snapping out his daze he ordered his small group to evacuate the survivors they all ran off to do so except Robin who was having no problem keeping up with them.

"THIS WILL END IT!" Onin shouted as he put all his momentum into a flying punch to the Mysterious Fighter which had such force behind it that It made the him drop out of Super Saiyan into base form spitting everywhere, he flew into the town, Onin slowly went out of Kaio-ken into base form, lowering himself beside the defeated Fighter who wore a mask and a Gi of questionable origins with A weird looking Symbol that looked like the letter O and V had a baby, kneeling over him Onin simply said "Good fight" he turned around and started to walk away, he walked up the road and saw what was probably the survivors of the attack being consoled by some soldier looking types, what he did notice is that when he came into view the townspeople suddenly shut up.

Onin sighed and walked over, a man with blue hair and a drawn sword walked over to him "stay right there friend," the man said shaking clutching the sword "were you with the bandits?" he grips the sword tighter.

Onin calmly smiling said nothing as he began to get a lock on their Ki's as to see if they were strong none were that notable, "No I was not" he begins "I was walking through then I saw the town on fire and I began to help the town" he looked at his hands "when that guy came out and well I'm going to guess you saw the rest" he sighed

"That seems like a simple answer" Frederick said Chrom started waving his arms at him

"We've seen him fly around and shoot beams of light from his hands! Not only that but someone like him was on the enemy's side what's to say they don't have more!" calming down Chrom turned to Onin "who are you?"

Onin smirked "I am Onin the second Time Hero, Also the last pure-bred Saiyan" Onin smiled

Chrom looked distraught "Saiyan? What's a Saiyan? Is it like a weird cross between some races?"

Onin put a hand to his head "Saiyan's are mystical warriors with various spiritual skills that allow flight and combat."

Frederick frowning "and you expect us to believe you came down from the sky just to help?"

"Actually I ended up here on accident" Onin said frowning. "I was practicing my skills when I hit my head and woke up in the woods." Onin looked at Frederick "You seem armoured up are you with a military or something?"

Frederick looking at the ground mumbled "…something like that yeah"

Chrom walked over to Onin with his sword in sheath "I am the leader of a small group known as the Shepherds If there are people who have skills even remotely similar to yours we will need your help" reaching his hand out "How would you like to Join the Shepherds?." Onin put his hand on his mouth tapping his upper right lip
"Ok I will but before I do, would you like to ask me any questions?" Onin asked
Frederick Stepped forwards "I believe I have a few," he says.

AN:

So uh I haven't written anything in a looong time so I decided one day when I had like 3 hours spare that I'd write some Fanfiction and this is what resulted, the ending isn't the best it was rushed and I don't like how it feels forced when I have at least three chapters out I'll revise the ending
