It all started with the basics. The King of Monsters had mated and produced three children, two of which died. The last child was seemingly destroyed mid-hatch by a new weapon the humans have made. However, the hatchling wasn't dead. She was instead turned into a pony millions of years into the future, and that pony was Twilight Sparkle.
She was raised with no idea of her true past, and was taught by her adoptive family and friends, as well as Celestia. She grew to be successful, and was even crowned a princess. However, everything changed when Godzilla showed up. When he found out that Twilight was indeed his daughter, he immediately took her miles away from Equestria.
However, that didn't stop her friends from coming for her need. Heck, they even went to the ends of the earth to bring her back to Equestria to stop another powerful threat. Twilight had to accept her past some time or another, and during the climax of the fight, she did just in the nick of time, and achieved a hybridized form. While her new form was based around her alicorn self, there were some Godzillalike features like a long tail, mouth full of fangs, fully functional hands and feet covered in black scutes, and oviparity. Don't ask how they discovered that last one.
Despite her new features, Twilight was accepted back into Equestria, she accepted her new form, and everything was going so well. It's been three months since the incident happened, and life in Equestria pretty much went back to normal. Well, as normal as it would when one of your rulers is the offspring of the King of Monsters.
Twilight Sparkle opened her eyes to see nothing but the open ocean. "Wha?" Twilight said. Ever since her transformation happened, she was no longer connected to the dream web, and her dreams operated without magical influence, which made them more random and sometimes, she doesn't even know she was dreaming. Twilight looked around to see more water around the raft she awoke to. "Is this another dream?" Twilight asked to no one.
Suddenly, the ground below began to shake, causing the waves to form and her raft to thrown about by the sea like it was a cork in a bathtub. Suddenly, a spire of rock stuck out of the water, piercing her raft and forcing the hybridized pony to propel herself into the air with her wings. As the spires went out of the water, it became more clear that those spires were the tops of mountains. Twilight watched as the mountains rose, with vegetation already on it. "I have to tell Celestia about this!" Twilight said when she saw the water receded away from the valley, revealing a Greek-looking city laying right in the middle, unscathed by the water, yet was covered in vines.
She flew as fast as she could before she remembered she could teleport. Charging her horn, she teleported to Canterlot to alert Celestia. When she came, however, she saw that Equestria was sinking. "No!" Twilight said as she tried to open the castle's door, which was already locked. When she looked into the window, Twilight saw that the whole castle was flooded in water. "No! It can't end like this..." Twilight said as she tried to claw the windows open with her front claws.
"IT CANNOT END LIKE THIS!" Twilight said, bolting out of her castle bed before breathing deeply. "It was just a dream." she thought aloud before looking out her bedroom window. The sun had just rose, and her little brother, Spike, was fast asleep in his bed. "Thank goodness..." she said as she looked at the alarm clock. Groaning, Twilight stretched her arms and wings to her sides before getting out of bed before getting out of it, using her magic to hands to pull the covers back into place, which was common because of the new way her sleep operates, and ever since she took that form, she didn't feel the need to do magic as much as she did when she was a pony.
She walked towards the kitchen, ready to cook some breakfast. Opening the fridge, Twilight pulled out some materials needed for her and Spike's breakfast. Spike got his usual gemstones, but Twilight's new body had led to changes in her diet, like the need to eat meat as well as plant matter. Thankfully, that wasn't much of an issue. Twilight's current breakfast consisted of blueberry pancakes with maple syrup. She was flipping the pancakes when a familiar purple dragon came in, already done with his molt three days ago. "Morning, Twilight." the little, drowsy dragon said with a yawn.
"Good morning Spike. How many gems do you want?" Twilight asked. Just about when Spike was ready to start, Twilight beat him to it. "Oh, who am I kidding. I know how you like it." the princess said as she put in just the right amount of gemstones for the growing drake.
"Twilight, what have you been thinking about for these last three months?" Spike asked as he looked towards the lavender hybrid pony, who had just finished baking her pancakes.
"I have been thinking about what happened three months ago. I knew these humans tried to destroy me when I was about to hatch, but think of all the technology they had. But unfortunately, and somewhat fortunately, the last of it is nothing but fossils, now." the Princess exclaimed as she sat down on the table. "Imagine that we could see some intact pieces of their tech, even if it is just for a little bit."
"Yeah, it would be nice to see it." Spike said as Twilight took a bite from some of her pancakes.
"Not that I'm getting ahead of myself or anything, these adventures are fun and all, but I had enough for a year." Twilight said, wrapping an arm around her little brother, who let out green flames, revealing two tickets to the year's Grand Galloping Gala.
"Would you look at that, tickets to this year's gala." Spike exclaimed as grabbed them and handed one to Twilight, who smiled sadly in response. "Don't worry about the nobles, Twilight. They're not much of a threat to you or your title."
"Oh, them." Twilight said. Ever since she arrived back, the more corrupt nobles were trying to remove her title, and there were a few families even going as far as to steal files and make false records. Those families weren't very smart to begin with, and were caught easily and stripped of their titles. "I know they aren't going to bother me, but I just remembered the craziest dream I had last night."
"Tell me about it."
Meanwhile, in the tropical jungles south of the Dragon's Lair, a lone hermit lived in a cave. Said hermit was mostly griffon in structure, but he some diamond dog (dogfolk) in his roots, hence the grey, shaggy fur and the dogfolk's signature spiked club on the end of his tail, though it was slightly darker than the rest of the tail. He had light grey feathers covering his head, and his beak and claws were dark grey rather than the normal yellow.
"Alright, I think I have it." the hermit griffon said as he drew on the map, painting a red X on his destination. "It shouldn't be too far from here. Here goes nothing, Matthew. Pretty soon, you'll find out what it is..." the griffon said, rolling the map up and putting it in an old vase where he keeps all his maps. He then turned his attention to his journal and began to write.
