HK-51: The Droid Assassin of Equestria

The room where Charming Thunder and his friends are in was where the pony they are going to talk to before they set off to the mountains. "Hi," Charming Thunder said. "my name is Charming Thunder. Me and my friends were wondering if you knew what this..."robot" looked like so that we can get a good picture of what it is. So can you please tell us?"

"I will," she said. "It...it was 1.8 meters tall, it had some sort of weapon on its back, the color of its metal was silver so shiny that you can see a reflection of yourself, and its head was roundish triangle shaped. Thats all I know."

"You got all that, Twilight?"

"Got it all," Twilight said as she was writing everything the crystal pony said.

"Thank you for your time. And nice meeting you."

"Nice meeting you, too. Come back safely."

"No need to tell me," Cadence said when the group exited the room. "I'm sure that I'll remember everything she said."

"We are going to the mountains now. Im sure it won't take long." Charming Thunder and the rest of the group then left to the castle to walk up the path to the cave that is in the mountains.

Charming Thunder and the mane six have been taking the trail as suggested for hours. Applejack was moving the cart so that they can put the robot in it to carry it back. "How much farther?" Applejack asked Charming Thunder. "My legs are starting to get tired."

"We're close," Charming Thunder replied as the group came to a stop to the entrance of the cave. "Alright. Shall we take a look inside?" Fluttershy then started to get scared and hid behind a nearest rock. "Oh come on, Fluttershy. Its just a cave."

"Yeah I know," Fluttershy said as she peeped her head over the rock. "A dark...scary...cave. Eeep!!" She then hid behind the rock again and got scared even more.

"Rainbow, if you please." Rainbow Dash then flew behind the rock and grabbed Fluttershy as the others started to walk through the cave. As they passed through the cave, they came across an opening and entered the room. There the group came face to face with the robot similar to what the crystal pony described.

"Ok we found it," Fluttershy said. "Now can we go? " She then started to shake due to how dark the way is on the way back.

"Yes. Twilight, Rarity, help me put it in the cart." The three unicorns then carefully levitated the robot to the cart. And they now headed their way back outside and return to the Crystal kingdom to show the princess their discovery.

"New discovery eh?" Shining Armor said. He returned from his duty and is in a discussion with his wife about the situation that has been going on while he was away. "And Twilight and her friends are bringing it here?"

"Yes," Cadence replied. "I believe so. and when they do, I would like to present it to Celestia once I get a reply to the letter I sent her--." A knock was then heard at the door. "Enter." Charming Thunder and the group entered the group with the cart covered with cloth. Twilight then noticed her brother in the room.

"Shining?" Twilight shouted with joy.

"Twiliey!" Shining Armor and Twilight then shared a hug. "I missed you, kid."

"Me too, BBBFF."

"Whats in the cart?"

"The discovery that was hidden in the cave of the Crystal Mountains," Charming Thunder said. "I give you..." He then levitated the cloth off of the cart and revealed the robot. "... the robot."

"Whoa. That's amazing." A squire then entered the room and gave Cadence the letter.

"Its from Celestia." She then unrolled the scroll and read it:

Dear Cadence,

I would love it if you and your brother would bring your discovery to Canterlot. If it is a robot, can you find a way to turn it on before you show me and Luna. See you soon.

Sincerely

Princess Celestia

"We better get ready to go to Canterlot then," Applejack said. "Somehow my back is killing me from carrying this cart with this heavy robot."

"Agreed," the Cutie Mark Crusaders said. Everyone then went to his shuttle and prepared to travel to Canterlot to present the robot and find out if it can be useful.
