WHAT I'VE DONE

by CROSSOVER KING


So let mercy come and wash away...

Twilight Sparkle was currently experiencing both the most exciting and the most terrifying moments of her entire life. On one hoof, she was afraid beyond belief as the sounds of gunfire and explosions were booming from all directions. Everywhere she looked, she either saw a Decepticon blowing up into pieces and spreading dozens of Energon shards everywhere or a royal guard being shredded into pieces and spilling gallons of blood everywhere. Needless to say, the battlefield as a whole was a truly horrifying sight to behold and Twilight had now realized how naive she was. This was not as bad as she had imagined it to be.

It was worse. Way, way worse.

On the other hoof, though, she was not flying across this extremely violent are at top speed all by herself. In fact, she was accompanied by her new interstellar friend Optimus Prime, who was slicing and dicing every single Decepticon soldier in front of him without hesitation as they traveled towards their main objective:

Retrieving the immensely powerful AllSpark cube from the clutches of the malicious Decepticon leader, Megatron.

No matter how many times she had seen it, Twilight was continuously puzzled by Optimus' complete lack of reluctance to tear his enemies apart no matter how big or small they were, compared to him. He was a soldier through and through. He did not have a slightest indication of fear on his face. He was prepared to do whatever it took to achieve victory. Though she could not explain it, Twilight was certain about sensing an aura of courage emanating from the Autobot leader and it was somehow making her slightly less afraid of the carnage taking place all around her. In fact, her confidence had risen exponentially ever since the battle started nearly twenty minutes ago. While she was utterly horrified by the carnage and was on the verge of completely freaking out at the battle's inception, she was now sending magic blasts at the optics of the Decepticons attempting to attack Optimus from behind or either sides without much reluctance. True, she was still terrified of her brutal surroundings, but she had learned to suppress that fear and she really had to thank Optimus at the end of this battle for inspiring her to do so. That is, if they could actually make it out alive.

As they came near the edge of the battlefield, they encountered a sight most shocking: Twilight's beloved mentor, Princess Celestia, was taking Megatron head on by flying around him and trying to shoot him with her magic while avoiding blasts from his fusion cannon. Although she was succeeding in landing direct hits at Megatron's chassis, her attacks were only causing tiny burns on the armor and Megatron was merely flinching as he was hit. Soon enough, he became so annoyed by this that he screamed in pure rage and clapped his hands hard enough to create a shock wave, which not only stunned Celestia, but also knocked her back a bit. Seizing the opportunity, Megatron sent a blast from her fusion cannon directly at her and though, she tried to deflect it with a sphere-shaped magical shield around her, it was annihilated with a single hit and the impact of its destruction knocked her out of the sky, causing her to plummet to the earth.

While Twilight was gasping with pure terror, Optimus was scowling at Megatron with pure rage. Before they could anything to save Celestia, however, a Destroyer came near them and emitted highly concentrated laser blasts from his gigantic cannon, This made the duo to dodge the attack as quickly as they could and once they were in the clear, Optimus began slicing the Destroyer's legs with his axe. Knowing full well that Optimus could defeat this behemoth on his own, Twilight immediately flew away to save her mentor.

Meanwhile, Megatron was standing on top of a heavily wounded Celestia who was trying extremely hard to get back on her hooves. However, she eventually failed to do so and Megatron exclaimed, "Pathetic! This is all the creature who controls the sun has to offer? Your devotion to insignificant notions like friendship, kindness, and peace has made you so weak that you could not even stand one cycle against me!"

Though she was in agonizing pain from her wounds, Celestia managed to glare at Megatron and said, "Do you think your method is better in any way? If I had tried it, I would've been corrupted by the same evil that once befell on my sister and become a tyrant that every single one of my subjects feared. This is the LAST thing I want to be!"

Upon hearing that, Megatron let out a sadistic chuckle and replied, "Fear is how you control subjects. Fear is how you keep order! FEAR IS HOW YOU CREATE HARMONY! You're either too naive or too foolish to realize this universal truth!"

Right after saying that, he raised his fist up to the air and prepared to crush Celestia with it. Before he could do so, however, a purple magical aura surrounded the princess and dragged her out of the way. A confused Megatron looked at the direction she was headed and saw Twilight using her magic to lift Celestia and flying away as fast as she could. he once again screamed in anger and touched the left side of his head before saying, "Barricade, intercept the two alicorns flying towards the front gates. Barricade? Barricade, do you hear me? This is Megatron!"

When he heard nothing, he became extremely confused. Barricade was one of his most loyal soldiers and he would always answer calls from him, no matter the circumstance. The only logical reason he was not answering at that moment was that he could be... offline.

A sudden surge of concern swept over Megatron and he touched the left side of his head again before frantically saying, "Brawl, do you hear me? Tell me you have a visual on Barricade. Brawl, come in! BRAWL!"

It was at this moment that the Decepticon leader realized that something was terribly wrong. Both of his lieutenants could not possibly be offline. There just had to be another reason for this lack of communication. However, as he gazed upon the battlefield before him, he realized that his original theory could be true after all. Everywhere he looked, he saw his soldiers being blinded by equine weapons and decimating each other in a chaotic manner. The ponies had known about their weak spots all along and had been using that knowledge to their advantage from the very start of the battle. Now, there were only about half a dozen Drones, two brutes, and only one Destroyer remaining, while the number of remaining pony soldiers was well over thirty.

Megatron's facial expression had now turned into pure shock and he just stood there pondering several questions buzzing in his head: Could this actually be possible? Are these tiny insects actually capable of eliminating a huge chunk of the legion while also defeating both Brawl and Barricade? Was it a mistake to underestimate them?

He was so distracted by these questions that he did not see the severed head of a Destroyer flying towards him until it hit him in the chest and caused him to fall to the ground. As he lifted the head off his body and got back up, he saw his mortal enemy Optimus Prime standing beside the now-headless Destroyer and holding his axe with both of his hands, ready for a fight. Deciding to give him what he wished for, Megatron tore the head in half with his bare hands and threw the pieces to Optimus. Right after the Autobot leader sliced both pieces, Megatron shot him in the torso and gleefully watched as the blast sent his opponent flying a dozen feet backwards. He then grabbed his mace from his back and charged at Optimus before viciously attacking him several times with the mace. Luckily, Optimus managed to deflect all of these attacks with his axe and finally, as both weapons struck each other, both combatants were locked in a stalemate.

"Even with all your power, you'll never be able to defeat me by yourself, Prime!", Megatron exclaimed while trying to push forward.

In response, Optimus began pushing back and asked, "Who said I was alone?"

He then quickly dashed to the left and immediately after that, Twilight appeared in his place before shooting Megatron in the left optic. The blast completely destroyed the optic and as Megatron yelled in agony, Optimus seized the opportunity to strike him with his axe so hard that it caused a huge cut on his chassis and sent him flying at least fifty feet backwards.

Twilight bumped his hoof into Optimus' fist and the two heroes started walking towards their defeated enemy, who was grievously wounded and was also leaking half a dozen Energon shards each second. Soon enough they were standing right in front of him and Optimus pointed at him with his axe before declaring, "It's over, Megatron. Your forces are on the verge of defeat. Surrender the AllSpark and I’ll convince the princesses to give you a fair trial."

As soon as he said that, a sudden realization dawned on Megatron. He then let out a dry chuckle and retrieved the cube from his back. As he showed it to them, he replied, "Very well. Victory is yours."

Optimus put his axe to his back and carefully tried to grab the AllSpark. However, only a second before he could touch it, Megatron immediately smashed it into the ground. While the impact did not destroy the cube, it caused it to emanate a blue wave of energy that spread to every corner of the battlefield. What was worse was the fact that the energy was bringing the pieces of the fallen Decepticons together and about half a minute later, the entire legion was back online.

As Optimus and Twilight looked at the sight before them in pure horror, a fully repaired Megatron stood up and shouted, "You should've realized by now! Against the power of this cube, THERE CAN BE NO VICTORY!"
