When Godzilla defeated Biollante, her spores went into the sky for one final time. A human girl's face could be seen by at least one man before he was shot. But that wasn't about the man. Some of Biollante's spores were unknowingly carried to the sky by Mothra and were sucked into a black hole, with the cells of the three merging with crystalline organisms and energy from supernovae, slowly evolving over thousands of years into a new creature. It was similar to Godzilla, but was blue, had a crown on its head, and had two large crystals on its shoulders. A new creature was born and emerged from a white hole somewhere in the galaxy.
The new mind its first goal: to take over a world that it never knew about. Its crystals enlarged and propelled it into space, causing it to fly towards a set location. It will take thousands of years for it to get there, and it will get there, at least it thought it.
--<Present Day>--
A small, purple alicorn walked into the library and began to read one of her books in front of a fireplace. Twilight wasn't born an alicorn to begin with. She was born as a unicorn up in Canterlot to Twilight Velvet and Nightlight, and got her cutie mark and unlocked her raw magical potential thanks to the sonic rainboom that Rainbow Dash preformed a long time ago. She is still in her teens and she is already so successful, even ascending to alicornhood and becoming the Princess of Friendship. So many challenges were beat, so many obstacles were overcome, and now, she even has her own castle. It was a long ride and look where she is now.
But suddenly, a there was a knock on the door. Twilight opened it to see a couple of Royal Guards standing outside. They bore expressions of tiredness and of fear.
"Princess Twilight, we have bad news from Manehattan. It was destroyed..." one of the guards said. Twilight dropped the book and stood up. She was afraid, yet spoke.
"What was it destroyed by?" Twilight asked.
"Well, for starters, it was bigger than the largest Ursa Major. It was a giant, bipedal, wingless dragon with grey scales and abnormally large spines on its back. The thing tanked our magic like it was nothing." another one of the guards said.
"Where is it heading?" Twilight asked.
Godzilla marched through the plains, thinking about what he had seen. These new insects, they threw everything they could at him, yet they were even less suited to deal with stuff like him than the humans. Technology-wise, they lacked electronics and cars, and trains are the only automated source of transportation. Planes weren't invented, and Zeppelins were the dominant air transport. Such a backwater land when compared to what he had seen, mainly because of their dependence on magic.
Sure, Godzilla knew very well of magic but he thought it was just an old fairy tale. Nonetheless, he was impressed by the fact that it turned out to be real, even though he was immune to it. But what he was unimpressed by was what these insects used it to do. They rigged nature itself. He saw them bump into clouds, zapping lightning at him. He hoped that it was nothing more than a form of security used against giants like him. The electricity had no effect on him, nor did rain nor wind.
Pitiful. To him, it was just pitiful. This race probably didn't face anything like him. As he marched forward, he stepped on something that almost made him scream. He lifted his foot to see what remained of a small town and some blood. Gross, insect remains. Ignoring the remains of the insects and the town, he marched forward and decided to march alongside a mountain range.
Some time later, he came across a giant bear with purple starry fur. Sure, it was big when compared to the bears he saw, but it only came up to his chest, even when in bipedal position. He had to admit, he was kinda hungry. So he pounced upon his kill without a second though. It fought him, but it was no match for the King of Monsters. Even without his atomic breath, Godzilla could still take on and beat this giant bear. He normally ate fish, but this thing really filled his belly.
Godzilla continued moving forward, marching along the mountains until he sees another settlement to take his anger out on.
"Oh dear." Twilight said. She knew exactly where it was heading. If it continued across the Crystal Mountains, then the Crystal Empire is its next stomping grounds. If her brother and sister-in-law were to be killed by that monster, she would not know what she would be able to do. It has to be stopped, but it cannot be stopped, it just can't.
But then she remembered something. When her magic was stolen by Tirek, she thought it was over, but then, she remembered everything she went through. She had her friends with her, and together, they unlocked the secrets of the Rainbow Power and defeated their magic-stealing foe, gaining her castle in the process. Friendship helped her revert Nightmare Moon back to Luna, defeat and reform Discord, stop King Sombra from taking over the Crystal Empire, and it gave her the means to defeat Tirek and return all the magic that he stole from the ponies. She reformed Starlight Glimmer, who is now her student.
If it worked on all these foes, then it must work on this new one.
"Call the girls. Whatever odds we face, we beat them together, and I'm certain that we'll be able to beat whatever that thing is." Twilight said. The Rainbow of Light is the only option that she could think of.
"Shining, Cadence, Flurry Heart, please be okay. We're coming to save you..." Twilight said as she walked towards the throne with her friends. If they can't defeat it, then Equestria shall be lost, but they have not lost before, and she was confident that they will not lose against the newest threat to Equestria.
