Author's note: There is no specific generation/incarnation for the transformers in this story. Use your imagination. If you like the movie versions, then that's the version they are. If you prefer the cartoon versions, then…you get the idea. Also note that I only rated it T for safety reasons, there are no "adult themes" and no language. I do not own Transformers or Frozen. But I do own my OCs

Prologue

A lone robot stood hunched over a computer. She was slender and her chassis was dark brown. On her there was a decepticon symbol that was scratched up to the point that it was unrecognizable, and a crude autobot symbol etched on her arm. She frantically pressed buttons in rapid succession, constantly looking over her shoulder.

"I have finally found her. Jazz and the others will be here soon. I can send the hologram directly to him. Yes, I can save her. There is still time. Oh I'm so proud of her. She has made a fine Queen. I have failed her….But Optimus prime will not. "

Before she could continue, an explosion was heard directly behind her. A three decepticons marched through the makeshift door they created.

"Hand over the disk to me and you may live to see us triumph" The one in the middle demanded.

"Ah Starscream, I see you came with your little posse. No I will never give you the file. You will have to take it." She declared.

"You will pay for your treachery Nudi! Starscream shot a round at Nudi but she anticipated his move and dodged the shot and fired her own gun at starscream. Unlike the sneaky decepticon, she did not miss. Starscream fell to the ground and the two minions flanking him pulled out their guns, and pointed took aim at her. She pulled out her energon whip and cracked it, silently daring the two lackeys to continue. She cast her weapon and she hit the minion on the right, relieving him of his weapon. The one on the left fired a shot and missed. The renegade autobot closed in on him and finished him off with a metal crushing hook to his optics.

"One down two more to" her thoughts were interrupted when a fourth decepticon walked through the hole.

"Nudi, you are weak, just like the defects you fight for!" The challenger bellowed.

"I will never give you the data Megatron! No matter what happens, I will never surrender the one I swore to protect!" Before she could continue, she was rushed by Megatron. She threw a punch towards his face but he effortlessly sidestepped it and grabbed her. In one motion he stomped his foot on her knee joint, breaking it instantly.

"No matter what you do, I will always be with her, and so will Optimus Prime! I cannot believe that I once called you master. I would rather die than serve you! Long live the autobots! Long live Optimus Prime!" She decreed, knowing that those would be her last words. She reached over and pushed the button, beaming the hologram, and whatever else the decepticons were after to the autobots.

"Such heroic nonsense" Megatron scoffed, before aiming his fusion cannon at a helpless Nudi. He fired his legendary weapon and she was completely blown apart.

Optimus prime gazed over the horizon of Cybertron with his piercing blue eyes. The land remained war torn and the autobots and decepticons fought on. The war was lost. But he had bigger problems at hand.

A smaller autobot named Jazz has just returned along with his strike team which included, Cliff-Jumper, Blue-Streak, and Wheel Jack. They carried with them, the latest decepticon plans.

"Optimus, I read the files but I don't get it. What's with this human and why is Megatron so obsessed with this human in particular?" Jazz turned on a hologram. It was a three dimensional image of a slender young woman, early twenties, with platinum blond hair, pale skin and blue eyes.

"Now is not the time to ask. Our mission is to protect anyone Megatron puts in harm's way. However, at some point it would be wise to investigate her value to the decepticon cause and quite possibly our own." Optimus replied.

"When should we do that?" Wheel-Jack inquired.

"When she is safe and ready to willingly reveal to us whatever information she possesses, if any." Prime concluded. Jazz walked to Optimus to hand him a small disk. The minute it contacted Prime's hand, the message played.

"If you are playing this message, then I have probably been terminated. There is not much time left. This is a private message for Optimus Prime" Nudi's voice stated. Optimus signaled the other autobots to leave and they obeyed.

"Continue" Prime commanded.

"I assume Jazz gave you the hologram of the human girl. Her name is Elsa, Queen Elsa to be exact. She is blessed with a beautiful gift. But Megatron intends to enslave her and abuse her powers for his selfish ambitions. As an autobot, I have sent Jazz the decepticon codes. They will grant you access to their database. As a friend, I ask that you protect Elsa from Megatron's clutches. As a friend, I ask you to watch over her. She is just barely an adult and yet she has an entire kingdom on her shoulders. In part because of her parents, she is emotionally unstable. Her younger sister has helped her overcome much of her inferiority complex but she is still without a mother or father to guide her. You are the last prime, please guide her, and nurture her, be the leader she deserves." With that the message and the recorder evaporated.
