A saiyan in Equestria?

"What makes you think that saiyan can be redeemed?"questioned Twilight

"I don't think he's evil at heart! He's been a murder slave for 16 years! Besides, he spared me! Isn't that some kind of sign?" countered Dash

"Fine, we'll try tommorow. I'll go with you, just for safety measures." Twilight said Reluctantly

"Yes!" said Rainbow Dash triumphantly

And so they went that afternoon to where Ato was camping out in the mountains alone.

"Hey so can I, um help you, alien guy?" asked Dash

"Piss off."

"Maybe we should head out, c'mon Rainbow Dash let's go." said Twilight

"No, not yet." said Dash, determined

"Hey, take this." Dash tossed a piece of bread to Ato and he caught it in midair, and then they left and repeated the process for a week, every day Ato became slightly less hostile, and each day, the bread from the previous day was gone.

And then there was monday

By monday, the whole process of Dash throwing the bread over to Ato was routine, but this time it was different.

"Listen, I have to train for... something, so you might as well keep this."

That response wouldn't seem like much, but Twilight and Dash saw a glimpse of a breakthrough, and though they walked away silently, they were beaming with hope and pride on the inside.
