Riksent City Square is a large area in the middle of the kingdom's city. It has a large fountain and has many shops in it. Usually, many people will be walking around here visiting the shops.

However, an unexpected event occurred at the city square. The citizens walking there noticed a purplish portal emerging above it. Much to their shock, monsters began to rain down from the portal and attack the city square itself. The monsters were humanoid in shape and clad in white biomechanical armor. Each of them was armed with claws and had yellow bone-like protrusions as well as a central core on their bodies.

As people ran away in panic, some were unlucky to be caught in the monsters' path and got injured. Soldiers soon came in to fight the monsters and take the injured to safety. In the midst of the chaos, Sanger, Elias and Geoffrey arrived at the scene.

"These monsters…" Sanger looked slightly surprised. "I know them. They're Einsts!"

"You know these monsters?" Elias said and he Geoffrey took their weapons out.

"They were aliens which I and my friends have fought before. But, they were supposed to have been destroyed,"

"Know them or not, we better get moving, mates!" stated Geoffrey. With that, Sanger and his companions rushed into battle. Soon, the Einsts had their attention focused on Sanger, Elias and Geoffrey. The battle became intense as the Einsts moved around swiftly.

"They're fast!" Elias swung his sword towards an Einst, only for it to dodge his attack.

"Aim for their cores!" Sanger shouted as he killed an Einst with his katana. "It's their weak spot!"

"Brace yourselves, mates!" Geoffrey said while swinging his rod around. "This is going to be a rough ride!"

"We're nearing the city square," Nicole informed the Freedom Fighters. The Sky Patrol is en route to the Riksent City Square. Accompanying the ship is the Soulgain, piloted by Axel. Earlier, Tetsuya arranged for Axel to accompany the Sky Patrol to the city square. Tetsuya also told the SRX Team, Ibis, Sleigh, Tsugumi, Glacies, Joshua, Cliana and Alfimi to head to the palace and guard Princess Shine upon arriving at Riksent's harbor.

"I know this is not the right time to say this but, that robot accompanying us looks pretty cool," Rotor stated.

"Isn't it?" said Sonic.

"Admirations aside, is everyone ready?" Sally asked.

"We're good to go," Rotor said as he and Tails held up their blasters. T-Pup barked to show that it is ready for combat.

"Alright, then," Sally said. "Freedom Fighters, move out!"

Back at the city square, the battle is not at Sanger and his company's favor. Sanger, Elias and Geoffrey are currently being surrounded by a massive horde of Einsts. The soldiers from earlier are standing at one side of the square watching the fight. They are doing so not because of cowardice but because Sanger had told them not to participate as he did not want any unnecessary casualties.

"Sanger, this is bad. Although your idea of not getting the soldiers involved in this fight is noble, it's proven to be ineffective for this situation. I think we really need their help-"

"I understand your concerns," Sanger interrupted Elias's words. "However, these enemies are far more than what the soldiers can handle," Sanger gripped his katana tightly. "But, even when we're outnumbered, so long as our souls do not waver, we will surely be able to win this fight!"

"You sure have guts, mate," said Geoffrey. Soon, the trio saw that Einsts are getting ready to attack.

"Here they come!" Elias said as he and his companions readied themselves. The Einsts dashed towards the trio from all directions and attacked them aggressively. In the midst of this, Elias held his sword out and it switched to a crossbow-like form. He then fired red lasers out of the crossbow's multiple barrels towards a few Einsts. But, the Einsts dodged the laser blasts. As the fight continued, the trio continuously received blows from their foes while defending themselves. Things clearly looked bad for them.

"This is bad!" Elias exclaimed. "At this rate, we'll be defeated!"

"Do not falter!" Sanger slashed an Einst with his katana. "Endure their attacks until we find an opportunity to counterattack!" While the fight went on, Sanger, Elias and Geoffrey saw the soldiers talking amongst each other.

"What is that?" one soldier said while pointing towards the sky. Soon, the soldiers as well as Sanger, Elias and Geoffrey were looking at two objects in the sky. They were none other than the Sky Patrol and the Soulgain. Upon arriving at the city square, the Sky Patrol stopped and floated mid-air. Out of it came the Freedom Fighters who descended down to the ground using their Extreme Gear.

"Wh-What are those things?!" exclaimed another soldier as he and his companions looked at the descending Mobians. As the Freedom Fighters descended, Sonic jumped off his Extreme Gear.

"Freedom Fighters…" Sonic performed a Spin Dash and launched himself towards an Einst. "…have arrived!" Sonic finished his words as he smashed into the Einst's core, destroying it. Sonic then landed in front of Sanger, Elias and Geoffrey.

"Hey, you guys alright?" Sonic turned towards the trio and smiled at them. As his teammates joined him, the Freedom Fighters were surprised to see Elias and Geoffrey. "Wait a second, why are you two here?" Sonic said to the duo.

"We'll explain later! Right now, we need to defeat the enemies!" said Elias.

"That aside, looks like we got more company, mates," Geoffrey pointed towards the Soulgain which had just landed on the ground. The robot's cockpit opened and out of it came Axel, armed with his trusty Mizuchi arm blade, along with Blaze and her group!

"Sanger!" Axel shouted as he and his company ran towards Sanger's group and the Freedom Fighters. "We're here to help!" As the Freedom Fighters saw Axel's group running towards them, the former were surprised to see the Bride of the Conquering Storm, Lightning Lynx and Honey the Cat among the latter.

"Conquering Storm and Lightning Lynx are here too?!" Sally exclaimed.

"Even Miss Blaze is here!" said Cream.

"And Honey's here as well! What's going on?!" Tails said. Soon, Axel's group reached the Freedom Fighters and Sanger's group.

"Hey, never thought we'd see you guys here," Sonic said to Blaze's group.

"We should be saying the same to you, Sonic," Knuckles said.

"More Mobians?" said Sanger. "Interesting,"

"I can't believe that we're fighting the Einst again. They were supposed to be destroyed," stated Axel.

"You mean these monsters?" asked Honey. "You've fought them before?"

"It's a long story. Anyway, we'll talk later! We need to defeat the Einst first!" Everyone began to prepare for combat as the Einsts circled around them.

"Ready to rock, guys?" Sonic said to everyone.

"Anytime," Sally smiled while readying her Ring Blades.

"Well, without further ado…" Geoffrey said.

"FREEDOM FIGHTERS, CHARGE!" Honey shouted.

"That's our line!" Tails said.

"Sorry, couldn't help it. This is just so exciting!" The Freedom Fighters sweatdropped at Honey's words.

"No time for jokes! Here they come!" True to Axel's words, the Einst charged towards the group.

"Spread out!" At Sally's words, everyone moved towards different directions and fought the Einsts. Sally swiftly evaded the enemies' attacks while slashing some of them with her Ring Blades. Sonic zipped around the battlefield hitting multiple enemies with his Spin Dash.

"I can't believe you're actually here, Honey!" Amy said to Honey while smashing her Piko Piko Hammer into an Einst. "How did you end up here?"

"Oh, well, let's just say this and that happened," Honey replied as she dashed around a few Einsts at blinding speed.

"I'm guessing it's got something to do with your fashion designs!" Tails exclaimed while he and Rotor were firing their blasters at the Einsts.

"How did you guess?" Honey gave Tails an astonished look while she kicked an Einst.

"Well, regardless of how you ended up here, it's nice fighting alongside my favorite fashion designer!" Amy said as she and Honey stood next to each other.

"And it's nice to fight with one of my greatest admirers!" Honey replied. "So, let's make this a sweet victory!"

"Yeah! Cos if it's not sweet…" As Amy spoke, an Einst rushed towards her and Honey. The two female Mobians then dealt a blow to the said Einst and spoke in unison, "…you're not wearing HONEY!"

Big caught an Einst with his fishing rod and swung it towards another group of Einsts, sending them flying. "Off you go!" he exclaimed as he threw the Einst he caught to one side. The Einst flew towards Storm and Lightning who had just destroyed some Einsts. The moment the Einst reached them, Storm and Lightning delivered a powerful lightning charged kick to it, obliterating the said Einst.

"Raijin Geri!*"

[*Japanese for Thunder God Kick]

Cream and Cheese were fighting against the Einsts in tandem. Suddenly, an Einst rushed towards them from behind. "Look out!" Bunnie who was flying around flew towards Cream. However, Bunnie realized that she would not make it in time!

Fortunately, Geoffrey who was nearby saw this. Quickly, he turned himself into a smoke-like form and flew towards Cream and Cheese. He then enveloped the two, carried them to a safer position and reverted back to his normal form. Seeing this, Bunnie quickly blasted the Einst with her arm laser.

"Hey, thanks!" Bunnie thanked Geoffrey.

"You're welcome, luv," Geoffrey replied.

Meanwhile, Knuckles and Axel had just launched an uppercut on an Einst, sending it flying upwards. After that, Knuckles unleashed a barrage of explosive punches on more Einsts while Axel sliced another with his arm blade. The two then stood back-to-back.

"You're not bad, Knuckles," Axel commented. He then saw Blaze exterminating a few Einsts with her pyrokinesis and added, "And so are your friends,"

"You're not bad either," said Knuckles. "I'd also say the same for him," Knuckles pointed at Sanger.

"Oh, him? He's a great swordsman," Axel said. "And a force to be reckoned with," Axel's words were correct as Sanger jumped up into the air and unleashed a devastating blow onto an Einst.

"Zankantou: Shippu Dotou!**" Sanger's katana cleaved his target with such force that the Einst was sent flying aback and exploded into flames. Antoine who was nearby became awed by Sanger's technique briefly.

[**Japanese. Roughly translated to Colossal Blade: Hurricane Raging Sword]

"Zat was quite a display of swordsmanship, Monsieur Sanger," Antoine stated.

"Your swordsmanship is something as well," Sanger said. "I had witnessed it earlier,"

"Shall we finish zis battle quickly then?" Antoine and Sanger looked at a few Einsts who were approaching them.

"Very well. Let us go!" Sanger proclaimed while running towards the Einsts with Antoine.

"En garde!" Antoine exclaimed.

The Einsts dwindled in number as the battle continued. The soldiers witnessing the fight were amazed at the Mobians' fighting capabilities.

"Amazing," one of them said. "Those chibi kemono are defeating the monsters!"

"I don't know who or what they actually are but, they are really awesome!" said another. Soon, a few Einsts remained on the battlefield. As everyone faced the remaining Einsts, the said Einsts began to retreat.

"Hey, they're running away!" Sonic said. Seeing the fleeing Einsts, Storm dashed towards their front in a burst of lightning.

"You won't escape," Storm said to the Einsts while charging up electricity in one hand. She then launched from out of it several lightning blasts in the shape of cats' heads.

"Raikodan!***" The lightning blasts collided with the Einsts and destroyed them. With that, the battle was over. As Storm went back to the group, Nicole congratulated everyone on their victory.

[***Japanese. Roughly translated to Thunder Cat Bullet]

"All enemies have been defeated," Nicole spoke from her handheld which was strapped to Sally's hips. "Nice job everyone!" Seeing that the battle was over, the soldiers cheered loudly.

"Well, looks like we got spectators," Sonic joked as everyone looked at the soldiers.

"I must say," Elias turned to the Freedom Fighters. "You guys are a sight for sore eyes! I never expected to see you guys here!"

"I should be saying the same to you, Elias!" Sonic replied. He pointed to Storm, Lightning and Geoffrey. "Plus, we never thought we'd see you guys again!"

"I believe we have not met before," Storm said to Sonic. "Yet why is it that you know me and Lightning?"

"It's a long story," Sonic turned to his teammates. "Right, guys?"

"Right…"
