A saiyan in Equestria?

"Why are you helping me?" Asked Rainbow Dash curiously

"I already told you, you're strong, so there's actually something going for you in life." said Ato philosophically

"Are you saying the weak have no point in living?!?!" said Dash horrified

"Yeah, pretty much. If you don't agree with my ideals, then fine, but stay out of my way." he said half-heartedly

"Stay out of your way? What kind of wacked out scheme are you planning?!" said Rainbow Dash

"My original plan was to collect resources, destroy the planet, find another planet, rinse and repeat, but if there are other people as strong as you on this planet, I'll keep it around to find to find even stronger foes." said Ato

"You just don't get it! Life doesn't revolve around fighting! Everypony has someone they care about right? Don't you?" said Rainbow Dash

The only response she got back was a look of confusion than a shrug.

"Love and care isn't what I've been exposed to, kid. For most of my life, I've been used to killing everyday joes who have the bad luck to stumble upon me. Do you think that being a slave taught to murder is going to teach you things like regret and pity? Look at your surroundings, so friendly and inviting, and then look at mine! I have seen SLAUGHTERS, so don't lecture to me about not showing kindness. Life may be all clouds n' sunshine for you but mine SUCKS!"  said Ato angrily

"I- I'm sorry, I had no idea." Dash whimpered

"Nobody does, kid." said Ato, who flew back off into the mountains.

Dash quickly returned to Twilight's house to report the new information, and that she was alive.

"Rainbow Dash, your back!" said Twilight relieved

"So how did the fight go? Lucky for that weird alien critter, none of the family got hurt, but I'm still peeved at it for blowin' up Sweet Apple Acres."

Rainbow Dash than explained how the fight ended in a draw, and how he spared her life.

"Girls, I may have some info as to the mysterious alien's identity, well more like his species." Immedietly after saying this Twilight had five shocked pairs of eyes looking at her.

"I think he may be part of race called the saiyans. According to some notes a wise scientist took, they're a very barbaric group of aliens who practically live off of violence, they were practically monkeys until another group of aliens traded them some advanced technology like armor and other crazy gadgets. They transform into giant apes under full moons unless their tail is cut off, and it's best not to get them angry or else. In the last hundred years they've been enslaved and near extinct thanks to a galactic tyrant. Lucky for them, that same emperor was killed by a saiyan just a year ago, ironic isn't it?"

Twilight took a breath after her long explanation and the rest of the mane six were practically roaring with laughter.

"Oh that was a good one Twilight! Tell us another one!" Pinkie said choking on her own giggles

"Twilight have you been feeling OK? Because I think you just jumped in the wrong haystack or something!" said Applejack chuckling

"Oh my word Twilight! That's ridiculous!" said Rarity

The only ones not laughing in the room besides Twilight were Fluttershy, who was scared of the possibility of having a bloodthirsty monster in her home, and Dash who thought the theory was plausible because it matched the description of Ato.

After everyone else left, Dash stayed behind to talk to Twilight.

"Twilight, I have to talk to you." said Rainbow Dash concerned

"Sure Dash, what's up?" said Twilight

"About the alien, I think he can be redeemed..." said Dash not expecting a pleasant response

"What!?! The saiyans are crazy!" said Twilight apalled and shocked
