At the NEST base in Washington DC, a strange golden chariot with a wooden crate in it, stands before the main entrance.
"Any idea what it could be?" a guard said.
"Maybe Prime knows." The other guard mentioned. "I will call him immedeatley!"
In the base, the autobots were just relaxing.
"I am bored Prime."
"Me too Sideswipe, but there is way nor reason to return to Cybertron, it practically doesent exist anymore, and building a spaceship is just to expensive for the human government." Optimus relpied.
"And the decepticons are all destroyed." Ratchet mentioned.
"Optimus Prime, sir, do you read?"
"Loud and clear, soldier!"
"Someone delivered a golden chariot outside of the base, care to check it out?"
"Affermative, I am on my way!"
When Optimus got there, he decided to open the crate and found a letter on the inside
"Take good care of these princesses" Prime read outloud.
When he took a second look, he found two foals(baby horses, or in this case, ponies) sleeping under a soft blanket.
"Hey, i know those ponies!" a soldier said to Prime "They are the goddesses of the day and night, Celestia and Luna."
"How do you know that?" another soldier asked
"I am a brony, google it if you want to know what it means."
"I will take care of these princesses, since i have nothing better to do." Prime declared.
"Affermative, sir."
When Prime reentered the base with the two sleeping ponies, everyone looked suprised at him.
"What are those?" Ratchet asked.
"These are my new daughters, Ratchet, Celestia and Luna."
"What?" Ratchet said suprised
"Someone left them outside of the base, so i decided to take care of them, since the decepticons are gone and i want to do something constructive."
Prime left to his quarters, and saw the first princess open her eyes and looked at him. "I see you are awake Celestia, i am Optimus Prime, your new father."
Celestia had no problem with her new father, Luna didnt either.
