They live 10,000 years in the future in a post-apocalyptic world. After many years of Twilight being a princess many foes have come and gone but one villain made robots from monsters and mixed them with forbidden magic. He tried to rule Equestira, soon he was able to make the monsters multiply (with magic) even after he was defeated. Twilight made a spell to destroy them all at once but it failed and disrupted the natural order of the universe or at least their whole world. So the world is kinda like a game, monster and anypony (even if not a robot) can level up. Twilight knew her friends needed to stay alive for a long time to help ponies everywhere so she turned them all in to part robot and they could all use magic in different ways. But for some reason it turned her into a robot too, Celestia is no where to be found and Luna is the master of the world right now (she went kinda crazy) but she is still a good leader and the only one they have. Right now they are in Ponyville but it's also Canterlot as well, it is the biggest safe zone in all of Equestira and they need to protect it with their lives and also do stuff for Luna.

“SPIKE!!!! NOOOOO!” Yelled Twilight.
“Twilight we both know this was the only way for you and the girls to live! I had a good life but, I know it's time for me to save everyone, good bye Twilight,” Spike jump into the super monkey wizard (level 47) and used the bomb that he had to blow the mother bucker to the shadow realm. But nothing happened; I guess it wasn't very effective.
“Spike you idiot, monkey wizards that are above level 30 are not affected by bomb and puppies. That's why I told you to stop!” sighed Twilight while putting her hoof on her face.
“So what do we do now?” Rarity questioned, “We can't possibly defeat this boss we need to flee, gather more potions and robot stuff because we obviously are robots I mean didn’t we mention that before?”
“No!!” yelled Twilight, “We need to combine to become super mega mage 2. Then we can use are super special awesome laser beam thing that's nothing like the k wave.”
“Do you think it will work?” Rarity frantically asked. ”It will work because WE HAVE MOTHER BUCKING MAGIC ROBOT POWERS!” Twilight yelled in response while she grabbed rarity and they combined to make super mega mage 2.
“Soon you will be dead monkey,” said Rarity Sparkle. (the name when the robots combined) But, it was only till now she realized that the monkey got bored of this crappy story and left.
“...........WE DID IT!” yelled the combined girls. They changed back to normal.
“Now where were we?” Twilight asked creepily as she looked at rarity.
“I don’t know! The real question here is where we were!?” Rarity responded confusingly.
And then they had pie and forgot about the dragon slave that died due to crappy awesome writing.
