A battle cry was heard outside of the palace gates. Elsa, Optimus, and Anna went to find megatron standing alone in the courtyard.

"Ah the overblown records clerk, the circuses reject and the spare have come to greet me." Megatron snarled. Optimus was about to speak but Elsa beat him to it.

"It's my turn Optimus" Elsa declared she rushed megatron but slammed into a wall of ice . Elsa did not remember making that wall of ice. It hit her like a sack of bricks; Megatron stole her powers.

"The snow Queens's gift is now mine! No one will stop me." Megatron cackled before shooting ice at the three. Elsa leapt in front of them and the ice hit her heart. She realized that she did not have enough strength to absorb it and she froze to a statue.

"You destroy everything you touch Megatron!" Optimus yelled while summoning an energon ax.

"Because everything I touch is food for my hunger, my hunger for power!" Megatron cackled while pulling out his mace. Optimus rushed him and knocked him to the ground.

"You will pay for this megatron" Optimus said as he punched Megatron in the stomach. Megatron sent a blast of wind to send Optimus reeling off of him. Optimus used a shield to block the ice but the shield shattered and megatron continued his furry.

Elsa heard a voice deep inside of her.

"You have shown your bravery as your sister has. Your journey is just beginning but you have proven your readiness for it. You will melt, you will fight, and you must win. "The voice said. She saw a vision of Her, her sister, Kristoff, Olaf, and Rosetta alongside hundreds of other humans slaving away in the death camps made by the decepticons.

"That is what will happen if you fail." The voice concluded. As a statue, Elsa could only watch in horror as megatron impaled Optimus Prime. All of a sudden, Elsa was forced to fight megatron…alone.

"Optimus loved me like I was his own daughter….I need to do this…I have to win, for my sister, Anna, my daughter Rosetta and my father…Optimus Prime" Elsa declared and then remembered that shielding them was an act of true love. So she melted. She felt her power surge and she formed an ice ax.

"Megatron! Stop this madness." Elsa pleaded.

"Why would I when victory is mine." Megatron said before blasting ice at Elsa. He then realized that it was no use as she effortlessly shrugged it off and sot her own ice back.

"So that's it then. We cannot kill each other and so we will be locked in eternal winter." Megatron deadpanned. To his surprise and anger Elsa laughed.

"Let me ask you something. You have your cards where you want them. How on earth will you control yourself when things are not going your way. You cannot kill Optimus because I stand in your way. Your victory has been denied." Elsa cooly told Megatron. She had her own emotions in check but Megatron was getting frustrated. Soon ice was shooting without him willing.

"I can't control it. These powers are tied to my emotions. Under normal circumstances I would not care if other are destroyed but It is no use-" Megatron was cut off by Elsa.

"The only one you're fooling is yourself. The reason that it bothers you is you need to be in control. If you're not in control…then you break down. Love is the answer Megatron. Love, I can help you!" Elsa extended her arm to Megatron. She did not want another to suffer as she did even megatron. Megatron smacked her hand away.

"No, no NO, I will not be denied!" Megatron said, beginning to panic. Elsa tried to calm Megatron down but he was enveloped in a swirl of panic. Megatron was shooting ice everywhere until he accidently struck himself in the chest. He regained his focus. He immediately realized all that Elsa said was true. But it was too late. Megatron had no love within his spark…But he knew someone who did. He knew who could save cybertron.

"Optimus Prime, take care of the rest. I give you the decepticon army to do with as you please. Optimus, Elsa, rebuild cybertron." Megatron said with his last breath before freezing solid. A cool breath escaped his mouth piece.

"Megatron….willingly surrendered to Optimus?" Jazz asked from the sidelines. Megatron began to melt as Elsa did.

"I don't understand. Why…." Elsa put her hand on Megatron.

"You were willing to let go of your pride. You surrendered to your mortal enemy because you thought it would save your home and people. You put the needs of others before your own, Megatron." Elsa said with a smile. Megatron's ice powers left him and Elsa felt them return.

"It's ok Megatron. They were just not meant for you." Elsa added. Megatron said nothing but nodded in understanding. Seeing that he was no longer wanted, Megatron flew off.

"So love will thaw?" Megatron said to himself before disappearing beyond the horizon.

After Optimus was repaired they boarded the Graveyard. The decepticons and autobots shook hands and bid each other farewell. Elsa had a melancholy look on her face. She curtsied to Optimus and said something she never wanted to say again.

"Do you have to go?" Elsa asked.

"You'll be fine Elsa." Optimus said before handing her and her sister a small device.

'What's this?" Anna asked

"It was a hologram device for sending three dimensional messages" Optimus replied.

"That belonged to Nudi" Skyfire added.

"Nudi?" Elsa asked confused.

"Oh that was her nickname. She was one of the few female autobots. She was a human once. The computer had a glitch when recording her name. It got it backwards. Her real name was Idun." Blustreak continued.

"M-mother?" Elsa stuttered in shock.

"She sent us to protect you." Optimus said. Elsa and Anna were fighting back tears.

"M-mother is still alive?" Anna asked with hope.

"She fought valiantly. But she was overrun by the decepticons" Prowl said sadly.

"Oh….." Elsa put her head down.

"But she wanted us to tell you that she was proud of you for finding the secret to controlling your powers and proud of you for being her daughter as well" Ratchet said. Anna gave up on not crying and she had her sister in a hug. Elsa was trying, and failing miserably to hold back the tears. Optimus bid them goodbye and the ship took off for cybertron.

The end

Please review. This was only meant to be a short story. Maybe I will re do it in a longer version when I have the chance. I had the entire story in my head from the minute I started typing the first chapter, including the sequel. I promise the sequel will be much better. But It won't be a crossover. Just a frozen fan fiction, ironically I am more eager to write the sequel than I was with this. You will definitely see more energy in my second one. When I finish I may come back and try to improve this one if you guys didn't like it.
