The group found a lot of Kronosians in front of the Casino Night Zone which was on fire and some of the Kronosians saw the group and attacked them. Luckily, they were prepared and defeated the Kronosians sent to attack them.

Afterwards, all of them ran as fast as they could to the Casino Night Zone and destroyed some Kronosians in their way. When they got in, they saw the bodies of Scratch and Grounder and some other former Badniks lying around.

"Turns out they got here before us and did some serious damage," said Sonic, examining the wreckage. "I think they probably came for that Chaos Emerald," said Twilight Sparkle. "We must get there quickly," said Sonic in an urgent tone, "Who knows how powerful they can become if they get just one," he said. "Didn't you say something about how all seven emeralds combined together that can make a person invincible?" asked Finn. "It might have different rules on different species," added Tails.

But at that moment, Spike shouted, "Something's coming for us." After he said that, the group turned to see several red lasers coming towards them and they left a line as the glided through the air towards them and before it hit their position, they stopped and they all turned to see an aura surrounding them and Silver had his hands out. "Cool," said Rainbow Dash, observing it. Then, Silver destroyed the homing lasers and put his hands down.

"How are you able to do that?" asked Twilight Sparkle to Silver. "A method that my master taught me," said Silver. After saying that, Silver then thought about the fact that the person they were looking for and his master had the same name.

"We have an emerald to find," said Finn as they all headed further inside.

When they got there, the found Mammoth Mogul using his powers to destroy Kronosians and was faring rather well and Finn noticed a Kronosian that stood taller than the others and it wore a long suit and had a gun for a hand.

"Mechbeast," said Lorina, appearing for a short moment.

The mechbeast stopped attacking Mammoth Mogul and turned its attention to Finn, Jake, Twilight Sparkle, Rairty, Rainbow Dash, Fluttershy, Pinkie Pie, Applejack, Spike, Sonic, Amy Rose, Tails, Shard and Silver. It fired several homing shots at them and when they ran, the homing shots followed them. "Well that explains where those shots came from," said Rainbow Dash as she was flying at a fast speed.

Sonic easily dodged the homing shots and jumped at the last moment when he got very close to a Kronosian warrior and it tried to slice him but it missed before it got accidentally destroyed by the homing shot.

Fluttershy tried her best to fly away from the shot that followed her and Shard used his laser cannon to dispel the homing shots coming at him and Silver used his powers to protect the others from the homing shots.

The mechbeast continued to fire more homing shots that sped toward them.

"Doesn't that guy ever take a break?" complained Sonic as he dodged the homing shots. Once again, it was Silver who got rid of them and this only angered the mechbeast and it only fired many more at them. But it was so busy firing that it didn't notice Mammoth Mogul charging up a blast of Ixian Magic and Shard and Silver were preparing their blasts and they all fired at the same time, destroying the mechbeast.

"That was too easy," said Shard, after helping destroy it. "Too easy?! I almost got killed!" shouted Rainbow Dash angrily toward Shard. "Well, the good thing is that we defeated it," said Applejack. "Not quite," pointed out Tails.

Everyone looked and saw several Kronosian warriors and the ceiling of the building tear off and there was a large creature that had eight red eyes, several spikes on its back and four massive spider-like legs.

"What is that?" asked Twilight Sparkle. "It's a Kronosian Behemoth, and they cannot be harmed on the outside," said Lorina. "So how do you kill it?" asked Sonic. "Its weakness is its mouth," said Lorina. "Then let's take it down," said Finn and then everyone focused their attacks on the Behemoth's mouth every time it opened until one of the blasts went deep inside of it and it blew into a million pieces which disintegrated into nothing a short time after landing on the ground.

Then, the group attacked and the remaining Kronosian warriors. Twilight and Rarity used their unicorn magic to blast Kronosians; Shard fired lasers from his laser cannon at the Kronosians, Silver used his pyshokinetic powers, Jake stretched his fist and squashed Kronosian after Kronosian and Sonic spindashed through many while Amy smashed many with her hammer and Spike shot fireballs at the Kronosians and Rainbow Dash charged many of them while Applejack gave strong bucks against any Kronosian that attacked her.

Finally, they destroyed all the Kronosians in the building and went to Mammoth Mogul's counter.

"I'm surprised that even though we both oppose each other, you still helped get rid of those creatures who would have ruined my entire business," said Mammoth Mogul to Sonic after he walked up. "We're not here for that," said Sonic. "Then what have you come here for?" asked Mammoth Mogul inquisitively. "The emerald that you have," said Sonic.

Mammoth Mogul's look dropped as soon as he heard the words "emerald." Then he pondered about it for a moment. "But just this once, and it's only for saving my business," said Mammoth Mogul, reaching from a drawer and pulling out the Grey Chaos Emerald. "Yes, we got another," said Finn. "Hold on a sec, we have to see if its fake or not," said Sonic. "Let me," said Silver as he walked up.

Then, he put an aura around it and sensed. "It is the real emerald," said Silver. "Well, that's good to hear," said Rainbow Dash.

The entire group walked out of the Casino back towards the Freedom Fighter Special. As they were walking, Finn asked Sonic, "So, where is the next Chaos Emerald?" "It's somewhere in Station Square," said Sonic. "What's Station Square?" asked Finn. "The capital of the United Federation which is one of our allies and that's where my ally, Shadow is," said Sonic.
