The next morning, we find Sonic and the trio in the dining hall enjoying some breakfast which mainly consisted berries.
While they were eating, Twilight kept sneaking glances at Sonic, only to turn away whenever he looked her direction.
Seeing this, Spike decided to start a conversation.
"So, even though you haven't been here to long, how are you enjoying the castle so far, Sonic?" He asked.
"It's not bad actually." Sonic responded, "The beds are really soft, the interior looks magnificent, and the food is flat-out amazing!"
"I'm glad you enjoy it." Princess Celestia said, "Any guest of canterlot castle is given the best treatment available."
"Speaking of which, I should really thank you for taking me in last night." Sonic said, "If you didn't, then I would of been a goner by now."
""There is no need to thank me, any Pokemon that needs help deserves it." Princess Celestia insisted, "No matter how different they may be.
"Sorry for changing the subject, but we still don't know that much about yourself Sonic." Twilight pointed out, "Sure we may know what Pokemon you are and what type you are, but we don't know what attacks you have and what your ability is."
"Now Twilight, there is no need to rush, we have all day to learn more about Sonic." Princess Celestia said.
"I'm sorry princess, I'm just itching to learn more about him." Twilight apologized.
"Actually, I don't mind." Sonic said, "I haven't had a battle in a while and I was originally going to find someone to battle today before last night's attack."
"Then let's get going already!" Twilight announced as she got off her chair and began to run out of the dining hall.
That was, until Princess Celestia caught her using psychic before placing her back on her seat.
"Before we do that, I believe it's best if we finish out breakfast first." Princess Celestia said, "You can't do any research on a empty stomach, can you?"
Hearing this caused Twilight to blush in embarrassment.
"Oh, right." Twilight nervously said before she and the others finished their breakfast.
A few minutes later, the group of four arrive in the castle's garden where they come across it's training area.
"Excuse me for asking princess, but since I'm going to be demonstrating my attacks I just want to know, who am I going to be battling?" Sonic asked.
After asking that, one of the Arcanine guards had stepped onto the battle field.
"Before we had our breakfast, I asked a few guards to help with your demonstration and that Arcanine was the first to volunteer." Princess Celestia explained.
"Are you sure this is okay?" Sonic asked, "I don't want to risk having one of your guards unavailable in case I accidentally make him badly hurt."
"No need to worry about that, all guards were trained to take large amounts of damage and still be standing." Princess Celestia reassured, "And as you already know, the castle nurses are excellent in treating Pokemon no matter how badly hurt they are."
"If you insist." Sonic said before stepping into the battle field.
Once Sonic and the guard were in position, Twilight quickly opened her pokedex again and turned on record mode.
"Care to take the first move, kid?" Guard asked the Sonic.
"No thanks, you go ahead and go first." Sonic replied.
"If you insist." The guard before charging at Sonic using quick attack.
However, just as the guard was about to hit him, Sonic suddenly vanished.
"What th- AH!" The guard exclaimed as Sonic hit his side with aerial ace.
"You need to be quicker than that!" Sonic said.
"Don't get your confidence up just yet." The guard warned before burrowing underground using dig.
Instead of flying into the air like any flying type would in that situation, Sonic simply stood still before closing his eyes.
In the sidelines, Spike was confused about Sonic's actions.
"Why isn't he moving?" He asked, "He's going to be hit if he doesn't!"
"I don't know Spike, but he seems to be concentrating." Twilight replied.
Back on the battle field, Sonic continued to stay still before suddenly opening his eyes and flew straight into the air, just as the guard came out from under him.
Taking advantage of the situation, Sonic used quick attack and struck the guard midair, causing said guard to crash into the ground. After that, Sonic then began to use rollout and charged at the guard.
This didn't go unnoticed by the guard as he jumped out of the way. Unfortunately for the guard, that didn't stop Sonic from turning around and charging at him again while still using rollout.
This process was repeated a couple of times before the guard saw that he had a clear shot and used flamethrower at Sonic.
But when the flames reached Sonic however, he pierced right through it and was able to strike the guard in the face, causing said guard to be knocked back.
Before the guard could recover from the attack, Sonic continued to strike him all over his body before finally knocking the guard into the air.
With the guard in the air, Sonic stopped using rollout and flew towards him, tying to hit him with aerial ace.
As Sonic got close however, what appeared to be razor-sharp teeth that were made of electricity formed in front of the guard's mouth, signaling that he was using thunder fang.
Sonic saw this but was unable to to pullout in time hand was hit by the electronic type move, before being knocked towards the ground. Fortunately for him, he was able to land on his feet, although he skidded back a little due to the fall.
Once he landed, the guard seemed pleased that he was able to land a super effective move on Sonic until he saw said Pokemon smirking.
Before anything else could happen, everyone noticed that a green aura had formed around Sonic. The aura lingered for a moment before fading away, leaving everyone besides Sonic himself confused about what happened.
Deciding that he didn't what to find out before it was too later, the guard used thunder fang again and charged at Sonic.
As the guard was about to reach him, Sonic used aerial ace and uppercutted the guard, launching him into the air. Sonic then used quick attack and began hitting the guard with a barrage of strikes. Sonic then finished it off by appearing in front of the guard and used mach punch in his face, forcing the guard to crash into the ground, leaving a large dust cloud afterward. Sonic then landed in front of the dust cloud and waited.
Once the dust cleared away, everyone saw that the guard didn't faint but was barely able to stand up.
Believing that she's seen enough, Princess Celestia spoke up, "That's enough the two of you. This battle is over."
After hearing that, the guard said, "It was a pleasure battling you, Sonic."
"It was nice battling with you too." Sonic replied, "And sorry if I was a little too ruff on ya."
"No need to fret, as the princess said, I've been trained to take large amounts of damage. A little rest and I'll be as good as new." The guard reassured before walking off.
After waving goodbye to the guard, Sonic saw the Twilight, Spike, and Princess Celestia were walking up to him with amazed looks on their faces.
"Wow Sonic, that was amazing!" Spike exclaimed, "I've never seen someone battle one of the castle guards with such ease!"
"I'm impressed myself." Princess Celestia said, "For such a small Pokemon, you a have a great amount of strength."
"Thanks." Sonic said as he rubbed the back of his head.
As much as she wanted too, Twilight restrained herself from going up to Sonic's face and bombarding him with how amazing and unique his battle strategy was.
After taking a deep breath, she then calmly asked, "Hey Sonic, if you don't mind me asking, what was that green aura that was around you after you were hit with thunder fang?"
"Oh that. That was my ability, chaos drive."
"Chaos drive?" Spike asked.
"Chaos drive greatly increases all my stats whenever I'm hit with a super effective move." Sonic explained, "It's helped me take out strong opponents that I would normally have trouble dealing with.
"A new Pokemon with a new ability! My life is just getting better and better!" Twilight exclaimed as she finished updating the data for Speedrift, "I can't wait to find out what other surprises you might have!"
"Sorry Twilight, but it's time you started working on your studies again." Princess Celestia said.
"Aww! Do I have to?!" Twilight whined.
Princess Celestia only responded by raising her eyebrow.
After hesitating for a moment, Twilight finally gave in.
"Okay." She said in a glum tone.
As Twilight and Spike were exiting the garden, Sonic spoke up.
"Hey Twilight! How about I come with you and and Spike?" He asked.
"What? Why?" Twilight asked.
"I'm not sure what I can do exactly, but can try and help you guys out in any way I can." Sonic offered.
"Are you sure? My studies can be challenging at times." Twilight warned.
"I'm sure I can take it." Sonic answered, "And if I'm confused about something, I have you guys to help explain it to me."
"If you say so." Twilight said before turning towards Princess Celestia, "I'll talk about my notes as soon as I'm done princess."
"I'll be waiting." Princess Celestia said before teleporting away.
"Well, lead the way." Sonic said to Twilight before they entered that castle.
A few hours later, we find the trio in the castle library as Twilight is focused on a book while Spike is carefully showing Sonic his moves.
Just as Spike was about to show Sonic his dragon breath attack, they heard Twilight call him out.
"Spike! Can get me a quill, a piece of parchment, and some ink?" She called.
"No problem Twilight!" Spike answered as he gathered said things and made his way towards Twilight.
"Here you go Twilight." Spike said as he handed her the items.
"Thanks Spike." Twilight said.
Once she had them, Twilight began to write something down on the parchment before rolling it up and teleporting it away.
"If you don't mind me asking, what did you write and where did it go." Sonic asked.
"I sent it Princess Celestia." Twilight responded, "After doing some research, I found a prophecy that states the return of Nightmare Moon, so I decided to warn the princess about it and how we should be prepared for it."
"Nightmare Moon?" Sonic asked.
"Nightmare Moon is an old threat of the equestria region that Princess Celestia banished to the moon a thousand years ago," Twilight explained, "According to the prophecy, when Nightmare Moon returns she will bring an eternal night upon the entire equestria region."
"Although that is really serious, are you sure that it's even true?" Sonic asked, "For all we know, it could be nothing more than a legend and it would waste the time of a lot of Pokemon if nothing happens in the end."
"Relax, I'm sure she'll believe me due to my loyalty to her and how I'm always honest." Twilight assured.
Not too long after, a piece of parchment appeared in a flash and landed in Sonic's hands.
"Looks like she already responded." Spike said.
"Since you already have it you don't mind reading it, do you Sonic?" Twilight asked.
"Sure no problem." Sonic responded before opening the parchment and reading it's contents to himself, gaining a nervous look as he read.
"Uh Twilight." Sonic nervously said, "I think don't think those precautions you wanted the princess to make are going to happen."
"Why is that?" Twilight asked.
"It's best if you read it yourself." Sonic said as he handed her the parchment.
Once Twilight began to read the letter, she at first felt a great deal of pride when the letter mentioned her loyalty and how the princess would believe her. Unfortunately, things when south when the letter then said that she should go out more. The letter then explained there was more in a young Pokemon's life than studying, so the princess decided to have Twilight supervise the preparations for Summer Sun Celebration in the town of pokeville. The final things the letter mentioned was for Twilight to make some friends and what she would have Sonic come with her so that she could continue observing him.
Aside the observing Sonic part, Twilight wasn't exactly happy once she finished reading the letter.
Spike (who was reading the letter over Twilight's shoulder), spoke up, "Well, she does make a good point."
"This cannot be happening." Twilight grumbled as she sat on a nearby stack of books.
"Twilight, although I've only known the Princess since last night, I can tell she's doing this for your own good." Sonic said, trying to calm her down.
"As much as want say something, I'm a little tired after a day of studying, so I'm going to bed." Twilight said as she made her way out of the library, "Goodnight."
"Goodnight." Sonic and Spike said back.
Once Twilight was out of the library, Sonic asked, "Is she always like this when something doesn't go according to plan?"
"Sometimes." Spike responded, "But she does have good idea, it's best if we sleep now so that we have some energy for tomorrow."
"If you say so." Sonic said as he and Spike begin to make their way out of the library.
"Goodnight Spike." Sonic said once they were out of the library.
"Goodnight Sonic." Spike responded before the two of them separate and head to their rooms.
The next morning, Sonic, Twilight, and Spike were on their way to pokeville with Twilight and Spike on the back of one of the Pedgeot guards while Sonic followed.
"I can't believe I'm doing this." Twilight grumbled.
"Come on Twilight, it can't be that bad." Sonic said as he flew in a little closer.
"And look on the bright side, the princess is having us stay in a library, also think of all the Pokemon you'll get to see." Spike added.
"As much as I like to possibly see some interesting Pokemon, I need to convince the princess about Nightmare Moon's return." Twilight responded, "Which is why we're going to to through the list of what we need to check on as fast as we can, that way, we can get to the library and I can find more information on Nightmare Moon.
"Come on Twilight, you need to learn to put the book down and have some fun for once!" Sonic exclaimed in a playful tone, "Plus the princess did say to make some friends while we're there."
"The fate of the entire region isn't resting on me making friends." Twilight replied.
"Let's just drop this conversation for now." Spike suggested, "Let's not worry about that until we get to pokeville."
"Looks like it won't be long now." Sonic said as he pointed ahead of them.
"We're here." He said as pokeville came into view.
