Note: Thanks for all the favorites and follows, guys.

Once Lorina fixed the plane using nanites, the group was once again able to get in the skies to their next destination. "Wow, how are you even able to do that? Asked Tails with awe at her work. "Something that Starrunner AI are able to do," said Lorina. "Interesting," said Tails. "But anyways, let's continue on with the journey," said Sonic. After he said that, the entire group stepped into their plane which took off.

In the flight, Twilight kept on asking Silver about his psychokinetic powers and about him. "So, you are saying that you are from the future and that you're master was that guy who gave us the Grey Chaos Emerald?" she asked. "Yes," said Silver. "But I do not know why my master was like this in the past," he said. "Another thing that's surprising is that aliens ruled over us all in the past," said Twilight Sparkle. "Yeah, it is," said Silver. While they were talking, Fluttershy looked with wonder on Tails as she had never seen such a creature like him before.

"So what does Station Square look like?" asked Applejack. "It's a very large city and it's inside of a mountain," said Sonic. "Its buildings are very tall," added Tails. "How much longer until we get there?" asked Rainbow Dash impatiently.

But just at that moment, the ship shook very hard. "Not again!" groaned Sonic. "Let's hope it's not that General Dienus guy," said Silver. All of them climbed to the top of the freedom fighter special to find that a massive creature was entangling the ship. It had red eyes, grey exterior, a serpentine body, tendrils, shrimp like legs from its belly and a dinosaur-like head.

It gave a loud roar at all of them and scared Fluttershy back into the plane. "At least it's not General Dienus again," said Finn. "Doesn't look that hard to beat," said Rainbow Dash. "Looks can deceive," said Silver. "Let me guess, mechbeast," said Sonic.

Sonic spindashed through its feelers but they instantly regenerated and struck down Sonic. Silver used his psychokinetic powers but it just lashed out a tendril at Silver and then squeezed the plane harder. "Can't we just have a break!" complained Amy as she jumped and rapidly hammer the mechbeast but it only annoyed it and it grabbed her and it seemed it was about to eat her when, suddenly, a rainbow dashed through the arm and rescued her and it was Rainbow Dash. "Thanks," said Amy.

Shard and the rest of the group threw many attacks at the mechbeast but it only regenerated from the attacks and when Jake tried to stretch to a large size and throw it off, it just bit Jake and continued to cling to the plane.

Then, as Finn was watching this, he had an idea. "Everyone, aim for the mouth," he shouted. "Won't it regenerate?" asked Sonic. "Let's just give it a try," said Finn.

So everyone fired all their attacks into the open mouth of the mechbeast and it exploded into many tiny bits which disintegrated while falling off. "Ha, if this is your idea of stopping us, this is pathetic," taunted Sonic towards the ski. "Um, Xanazor isn't there," pointed out Finn. "I'm just saying as an insult if he hears it right now," said Sonic.

"Uh, guys," said Tails. "What," replied Sonic. "The Freedom Fighter Special once again needs repairs but still, we've arrived at Station Square and it is being invaded," he said with concern.

All of them went to look at the mountain. "So it's inside there," said Rainbow Dash, remembering what they said earlier"That's the last of our problems," said Applejack.

All of them looked to see armies of Kronosians going into some holes drilled into the mountain side and a large creature walking over drilling holes with its laser drill.

"That thing seems to be the source of all the holes in the mountain," said Tails. "Then we should destroy it before we continue with Station Square," said Sonic. All the others nodded in agreement. "But we're going to have to do it on foot," said Tails, "Since the plane was heavily damaged by whatever that things was," "Mechbeast," corrected Finn. "Can't we just get Lorina to fix it?" asked Twilight. "We could but it would take a while and Station Square would be rubble by then," said Tails. "I have a feeling that they invaded it for the Chaos Emerald," said Sonic.

The group including Tails ran up the mountain to confront the mechbeast while also destroying some Kronosians in their path. While climbing, they were sure not to fall into the drilled holes by accident.

When they finally reached the place where the large mechbeast was, they were terrified by its massive size. "Hello, puny worms," it said in a robotic voice. "You can talk?" asked Rainbow Dash, surprised. "Of course, and now you die!" it shouted as it aimed its drill at them and fired but the group scattered before the drill impacted.

"Die!" it shouted as it continued to try and hit them with its laser drill.

"You will not stop me from drilling into this city if that is your intention," it said in its robotic voice.

"Take out the drill," shouted Tails as he was flying to avoid the mechbeast's drill. "On it," said Sonic as he spin-dashed through the drill, partially damaging it, but it still functioned. "Damage all you like but I won't stop drilling until this city is destroyed and the Emerald found," it said and tried to step on them with one of its legs but they dodged and Jake ripped off that leg.

Then he stretched and tried hard to shove the mechbeast off the mountain but it didn't budge and responded by smashing Jake with its laser drill. "Ouch," said Jake as he fell down and fainted from the wound. "Silver, can you push it off or do something to it with your powers?" asked Twilight. "I'm afraid I can't because it'd to large for me to move," said Silver sadly.

Meanwhile, Sonic was spin-dashing against the mechbeast and it kept on trying to blast Sonic with its laser drill when suddenly, Amy Rose jumped up and brought down her hammer on the mechbeast's laser drill so hard that it exploded.

"You damaged my drill!" shouted the mechbeast in an angry voice. "But you'll see my smashing skills," it said. Then it began to randomly hit places in a fury where the group was standing at, forcing them to repeatedly dodge. "Wow, this guy has some issues," commented Rainbow Dash while darting to avoid it. When it was smashing, it injured many of the group and Fluttershy, not willing to stand to watch this stared at the mechbeast. "You stop what you are doing!" she said angrily at it. It obeyed instantly in fear and stopped.

While the mechbeast was busy caught in Fluttershy's stare, it didn't notice that Shard flew to the back of it and found a panel and opened it. He looked with fascination at what he found which were lots of switches and aimed his laser cannon and fired.

Meanwhile, the mechbeast was still smashing but then exploded it many pieces which all fell down. Everyone turned to see that their savior was Shard.

"Wow, thanks and for once, my robot double, you did do very good," complemented Sonic. "Your welcome," said Shard and he flew with the team.

"Now time to save Station Square," said Sonic and they went to the entrance.

A few minutes later, they had gotten inside to Station Square to discover that there were many corpses and civilians all running from Kronosians and Kronosians causing destruction and chaos. "This place would look better if those brutes didn't cause this much damage," commented Rarity on her surroundings. "Now's not the time," said Twilight to Rarity.

At the moment, everyone saw a large red robot gunning down several Kronosians but it was being overwhelmed. At the moment, Twilight shot several blasts at the Kronosians over the robot, destroying them. The robot looked up to see his attackers were gone and Sonic, Amy, Tails, and a few strangers he did not recognize. "Stop it right there, unidentified lifeforms," said the robot as it aimed its guns at them. "Hold on a sec, Omega, these are my friends and we are here for the Chaos Emerald that you have," said Sonic.

Omega lowered his weapons and said, "For what, hedgehog?" "A quest to defeat Xanazor," said Finn. "Who is this 'Xanazor'?" asked Omega. "Long story, but where is the emerald?" asked Finn. "Somewhere in the G.U.N. facility and my fellow agents, Shadow and Rouge are most likely guarding it," said Omega.

"Thanks for the information, Omega, now let's go," said Sonic. "Wanna race there?" asked Rainbow Dash in a competitive tone to Sonic. "You bet," he replied and the two raced with Shard flying after them while the rest ran very hard to keep up.

A few minutes later, by the time the rest of the group had caught up with the three, the three were impatiently waiting and the rest of the group were panting very hard. "It took us a few seconds to get here without breaking a sweat while it took you a few minutes to get here and you are already sweating," mocked Shard. "Whatever, where is the facility?" asked Finn.

Suddenly, as if on cue, there was a loud explosion and a black and red hedgehog got tossed out. "Shadow?!" asked Sonic in shock when he saw him. Shadow got back up and went back into the building. "Let's go," said Sonic and they went in.

When they got in, they found out that Shadow and a bat were fighting off against a cat-like mechbeast and another robot that didn't seem to be Kronosian. "Sally!?" said Sonic, surprised that his roboticized former loved one was here.

Upon hearing it, Mecha Sally said, "Enemy detected, terminate!" in a robotic voice and headed toward Sonic. Sonic responded by spindashed her, throwing her off. "Who is that?" asked Rainbow Dash. "My former love, until she got robotocized," said Sonic. "What is roboticized?" asked Rainbow Dash. "It's when someone gets turned into a robot using a machine and they lose their free will and based on what Lorina said, I think the method Kronosians are created is much worse than roboticization," said Sonic. Rainbow Dash looked a bit grim when she heard that. Amy Rose felt a tiny bit jealous when Sonic mentioned Sally Acorn.

Then, Mecha Sally went to attack the others. Jake stretched into a wall to protect them but quickly receded in pain after many slashes from Mecha Sally's swords. Finn leapt at Mecha Sally but she grabbed his legs and flung him to the floor. Spike spat out a fireball at her but she avoided it and punched Spike out. Applejack galloped to buck her but she avoided and kicked her aside.

When she tried to attack Silver, he just held her in place with his psychokinetic powers and no matter how hard she tried, she couldn't break free. Twilight helped Silver with her magic just in case. Finally, Silver used his powers to turn off Mecha Sally and she fell to the ground, limp. "What should we do with her?" asked Twilight. "Lets leave her here for now," said Silver, before he went to join the battle.

Meanwhile, the group had stepped into the building and they saw the red chaos emerald in a safe at the top and Shadow and Rouge fighting off against a cat mechbeast. "Little help?" asked Rouge as she was helping to fend off against it. "It's about time you showed up," said Shadow.

"Sheesh," said Sonic. "Who are they?" asked Shadow, pointing to the rest of the group. "It's a long story, but we're here to get the Chaos Emerald but since the Kronosians arrived, we're also here to get rid of them," said Sonic, "How did you know the names of these strange invaders," asked Shadow suspiciously. "It's another long story, but we'll help you destroy this mechbeast," said Sonic.

The group all gathered to face the cat mechbeast. Shadow was the first to attack and he tossed a Chaos spear at it but was agile enough to dodge it only to be spindashed into a wall by Sonic.

The mechbeast recovered from Sonic's attack and got back to its feet and leapt at them. Before it could hit them, Jake got in the way and stretched very large and pushed it into the wall.

Then, the sprinted and fired many blasts at them and attacked them at a very fast speed so quickly that they were all taken out. Then, the mechbeast ran up to get to the Emerald safe but got hit in the back and fell down. It got up and saw that its attacker was Shard who then blasted it with his laser cannon and then kicked the mechbeast down.

When Shadow regained consciousness, he found the injured mechbeast lying on the ground and instantly blasted it with a Chaos spear. The mechbeast exploded and the pieces disintegrated.

Shadow looked with wonder at what just happened in front of him and looked at the others, who were just recovering.

"Is it over?" asked Tails. "Yes," replied Shadow. "Anyways, can we have the Red Chaos Emerald?" asked Sonic. "Sure, if it can stop this threat you mention," said Shadow.

"Thanks," said Sonic as he went up to the safe and got the Red Chaos Emerald. "I will also join your quest along with Team Dark," said Shadow. "New members already?" said Finn, surprised. "This is going to be more successful than I think," he said. "It is," agreed Jake.

At the moment, they heard explosions and saw a large group of Kronosians marching to their location. "You can join our team, but first, let's kick some Kronosian butt," said Finn. Then, all of them charged to attack the Kronosians.
