The princesses have no idea that there are dinosaurs in Equestria or that they even came to Equestria. But, that's all about to change.
It is night in Canterlot and mostly everybody's asleep, except the royal guards and Princess Luna.
Normally, Princess Luna watched over Canterlot at night and Princess Celestia would be asleep, but strangely, Princess Celestia couldn't sleep.
No matter how hard she tried, she just couldn't. "What is up with me not going to sleep?" she asked herself.
So, she decided to go and get a drink of water. She walked through the halls of the castle before she reached the cafeteria.
She walked across the kitchen to the sink.
She rinsed out a glass and pored cold, fresh water into the glass from the sink faucet.
Immediately, she drank the whole thing in one gulp. But, she was still thirsty. So, she filled up again and drank it all down in another gulp.
She had five glasses before her thirst was clenched. She wiped her mouth with her hoof, swiping the water around her lips away.
"Ah, there's nothing like a cool, refreshing drink of water" she said to herself. Then, she headed back to her room.
Outside the castle walls of Canterlot, something was stirring.
Through the Everfree Forest, trees were moving, breaking, and snapping and large foot steps could be heard.
Then, bursting through the tree line was a large, carnivorous dinosaur. It was huge, being 40 feet long and 12 feet tall at the hip.
This...was Tyrannosaurus Rex, the king of the dinosaurs. It lived during the Cretaceous Period, 68-65 million years ago.
It was the greatest predator ever to walk the Earth and also the last.
Tyrannosaurus died when the giant meteor struck the Gulf of Mexico, along with all the other giant dinosaurs of the Cretaceous that lived around the same time as T-Rex.
Now, your probably wondering how and why Tyrannosaurus was the top and most feared predator of its day when it had tiny arms as long as a person's arms that are completely useless with only two claws on them.
Well, the answer is...its mouth. It's mouth was 5 feet long and has over 60 teeth that were between 9-12 inches in length.
They were perfectly designed for eating everything on a creature, from meat to bone.
Not only that, T-Rex has the strongest bite force of any animal ever, next to sharks and crocodiles.
It had a bite force of over 12000 pounds per square inch. That's equivalent to 6 tons.
This T-Rex is a male. Normally, males are smaller than the females, but this guy is as large as the average female, an extremely rare occurrence.
He looked across the landscape for prey, but nothing interested him. Then, he saw Canterlot. Canterlot, to him, was a large, lit object.
The lights seemed to attract him. So, he headed to Canterlot to check it out.
An hour has passed, and he finally reached the walls of Canterlot. He sniffed the wall and it was like any other barrier.
The lights were on the other side and he immediately knew what to do. Using his full body strength, he smashed into the wall.
He did it again and again until the wall burst open. He stepped through hole in the wall and into Canterlot.
Celestia was in her room reading a book when she heard the wall crash and break open. She ran to her balcony and looked.
There was a hole in the wall on the east of the city. She looked and Luna strangely hadn't noticed. So, she decided to investigate.
When she arrived to the wall, she noticed a dark silhouette entering into the city. So, she decided to follow it silently.
She had never seen anything like it before, but still couldn't make it out in the darkness. The T-Rex had no idea Celestia was following him.
He rounded a corner and into the light of a lamp post. Finally, Celestia could see what it was, but she was in for a shock.
It was like nothing she had seen before. She at first thought it was a dragon, but no dragon looked like that.
The T-Rex sniffed the air, then sniffed the ground. Celestia grew nervous, thinking it would detect her. So, she quickly flew on top of a building.
The T-Rex looked where Celestia was, but since she wasn't there anymore, he shrugged it off and moved on. Celestia watched him as he continued on.
But then, he picked up the scent of something. He followed it until he came to an alleyway.
He looked down the alleyway and two ponies came into view at the end of the alleyway. T-Rex have a keen sense of smell and excellent eyesight.
So, they can track prey and see it before it sees them. The T-Rex, seeing the ponies as food, silently crept down the alley way.
Celestia followed the T-Rex and landed on the buildings above the alleyway, the T-Rex, and the ponies.
The T-Rex arrived at the end of the alleyway and watched as the ponies passed by. The darkness concealed his large size.
He was about to sneak out when one pony, a mare, spotted him and screamed. The T-Rex looked where she was and let out a thunderous roar at her.
The roar was so loud that Celestia had to cover her ears. He got up from his crouched stance and chased after her.
The roar was so loud that it echoed throughout Canterlot, waking everypony up and putting the guards and Princess Luna on alert.
Celestia knew what to do. She had to stop the T-Rex and get it out of the city. So, she flew after it. The mare ran for her life as the T-Rex chased after her.
As she ran, ponies came out of there houses and watched as the T-Rex and mare ran through. Then, she quickly turned and ran into a tight alleyway.
The T-Rex lunged at her with open jaws but missed. Then, he followed her into the alleyway, but only his head could fit through.
Knowing he couldn't fit, he roared after her as she continued down the alleyway. He then freed his head from the alleyway.
Then, all of a sudden, a bright light flashed on him.
He looked where the light was coming from and there was a whole legion of guards, spears held right at the T-Rex.
The unicorn guards flashed their bright lights from their horns on the T-Rex, while some had there horns ready to fire.
He slowly backed up and growled at the guards. Then, Princess Luna landed in front of the legion and stepped forward, her wings spread out.
"Hath it there, foul beast. You come into our city and threaten our ponies, we're going to have to ask you to leave" Luna said.
But, dinosaurs aren't really good listeners. The T-Rex, instead, let out a thunderous roar at them and that triggered them.
"HOW DARE YOU DEFY ME, UNGRATEFUL CREATURE! ATTACK!" Luna shouted and the guards ran forward, spears forward.
But, little did they know was that T-Rex were natural born killers. The T-Rex let out another roar and charged.
He smacked a guard aside with his tail and stomped on another with his foot, killing him.
A guard stabbed him in the thigh and he reached around and snatched him in his jaw. Using all his bite force, he crushed the guard in his mouth, even the armor.
The guard screamed as he felt his bones being crushed. When the guard was dead, the T-Rex swallowed him whole. Then, he spat out the armor.
It landed in front of the others and their expressions were completely blank. "That thing can crush armor!?" a guard said in utter shock.
"RETREAT!" Another shouted and they immediately ran back for the castle. "Get back here, cowards!" Luna shouted after them.
Then, a drop of saliva fell on her head. She slowly turned around to see the T-Rex looking at her with an angry, evil expression.
She immediately fired her lightning-like laser beam in its face, stunning it momentarily. When it recovered, it let out a thunderous roar at Luna.
Luna knew she couldn't take it on by herself, so she retreated as well. But, the T-Rex was now on her tail.
She flew as fast as she could after the guards, but the T-Rex was gaining. Soon, she caught up with the guards.
The T-Rex caught up with them shortly after Luna caught up and roared at the legion and they screamed in response.
But then, a guard tripped and fell on the road. But then, he looked back as the T-Rex closed in. He screamed as the T-Rex stepped on him, crushing him.
He was caught on the T-Rex's foot for 3 more steps before falling off the T-Rex's foot. He was left as a smashed and crushed mess on the road.
Celestia, meanwhile, was following the T-Rex. She finally caught up with it.
Seeing that it was chasing her sister and the royal guards and that they were heading for the castle, she had to act now.
She flew down and fired a beam shot at the T-Rex. It landed on the T-Rex's neck. The T-Rex stopped and roared in pain as it had scorched the T-Rex's neck.
Then, he turned back towards Celestia. "Over here you big reptile!" Celestia shouted at the T-Rex. The T-Rex responded with a roar.
She then lit her horn and that seemed to attract the T-Rex. She waved her horn back and forth and the T-Rex followed it.
Then, she immediately turned around and ran. The T-Rex roared again before chasing after her.
"Celestia!?" Luna shouted, seeing her sister dealing with the T-Rex.
"Take the guards and go back to the castle. I'll take care of this guy" Celestia shouted back to her as she ran away.
Now that Celestia had the T-Rex focused on her, all she had to do was get it out of the city.
She ran as fast as she could, but the T-Rex was slowly gaining. She saw a sign ahead and she quickly ducked underneath it.
The T-Rex smashed through the sign, still on Celestia's tail. Now, the T-Rex was getting closer.
She saw a cart and she leaped over it, but the T-Rex smashed into it, causing it to roll after Celestia.
Luckily, it stopped rolling shortly after and the T-Rex destroyed it by stepping on it. Celestia saw the smashed wall ahead.
She immediately switched to flight and flew as fast as she could.
But then, as soon as she was about to go through the hole in the wall, the T-Rex unknowingly gained up on her, roared, and smashed his head into her, knocking her aside.
She crashed onto the ground hard, almost knocking her subconscious. She opened her eyes to see the T-Rex stomping slowly towards her.
When the T-Rex was over her, she knew it was over. The T-Rex roared and she covered her eyes as he lowered his jaws upon her.
But then, she felt a tickling on her face. She opened her eyes to discover the T-Rex was licking her on the face.
"Huh, your not a monster after all" she said to herself. She got up and patted the T-Rex on the side of the face.
Then, Luna came from out of nowhere. "Celestia!?" Luna screamed, seeing the T-Rex licking Celestia on the face.
"Don't worry, sister. He's nice" Celestia assured Luna. Luna sighed in relief. The T-Rex turned towards Luna and walked over to her.
He slowly bent down and nudged her in the face. A smile formed on Luna's face as the T-Rex nudged her.
She responded to the T-Rex's gesture of kindness by patting him on the side of the face. "Well, your nice after all" Luna said and the T-Rex let out a soft purr.
Now that they've befriended this creature, Luna and Celestia wondered what to do with it. "What do we do with him?" Luna asked.
"We don't even know what he is" Celestia replied. Celestia looked at the T-Rex. "I think we should keep him" Celestia said.
"Sister, are you crazy!? We can't just keep a creature where we don't know about it or its origin" Luna said.
"Well, if we let it go, we won't know more about it" Celestia said. Luna hesitated for a second, but Celestia was right.
"Alright, we'll keep him" Luna said. "Excellent! I already thought of a name for him" Celestia said.
"Oh, and what would that be?" Luna asked curiously. "Rex" Celestia said and the T-Rex roared in agreement to the name. "Well, he seems to like it" Luna said.
Celestia smiled and the T-Rex smiled back to Celestia. Then, the 3 headed back for the castle.
Next Time: The Mane 6 will head to Canterlot to discuss with the Princesses about the Dinosaurs.
