Later while the echidnas of Albion resettled into the city, Knuckles decided to take his mothers advice and rest, but something was on his mind.
"Something wrong, Knuckles?" Lara-Le asked.
"It's just that I'm surprised that Thrash hasn't got word about my rescue mission, but I guess it's better off if he didn't know that," Knuckles answered worried about what Thrash might try to do if he does find out.
"Well next time we'll be ready. I still don't know why he double crossed us," Lara-Le said before Knuckles remembered something.
"He mentioned that my people experimented on his, that's why he imprisoned everyone in the first place," Knuckles pointed out.
"But that was during the forgotten war, our ancestors were the ones responsible for that, we could have reversed the damage," Lara-Le explained.
"That's what I tried to tell him, but he didn't listen. I really shouldn't worry though, for all I know, Thrash may stay erased since Robotnik's super Genesis wave hit," Knuckles pointed out unaware that somewhere far from Albion, Thrash was watching the city being rebuilt and gets angry.
"That red dirtbag ruined everything," Thrash said in rage before punching a tree.
"If he wants to play that game, I guess I'll just have to kill him. Him and everyone in that city, but how do I accomplish such a thing without getting his attention?" Thrash asked himself thinking.
"You want to know how?" A male voice asked before thrash looked to see a shadowy silhouette standing behind him, he looked like Sonic which confused Thrash.
"And you are?" Thrash asked.
"I'll introduce myself in a moment, but answer my question," the silhouette demanded.
"Yes I want to know," Thrash pointed out.
"You remembered the master emerald correct?" The silhouette asked before Thrash remembered what he's talking about.
"Yeah," Thrash answered.
"You'll need that and a few gems called chaos emeralds to get what you want," the silhouette explained.
"How do you know about all this?" Thrash asked before the silhouette stepped into the light revealing itself to be a green male hedgehog with a biker jacket, sunglasses, white gloves like Sonic and black and green shoes, his name was Scourge.
"Let's just say I have experience," Scourge answered.
"Okay then," Thrash said after a couple of seconds, later him and Scourge arrive at a cave at an unknown location where an orange female fox in black clothing named Fiona is waiting.
"So this devil thing is gonna help us out?" Fiona asked.
"If we help him eradicate the echidna race in return," Scourge answered.
"And this is?" Thrash asked.
"My girl, Fiona, she's the only remaining member of my team, the rest were wiped out by that light," Scourge pointed out as Thrash remembered.
"Yes I'm aware of that light," Thrash said, "is there anyone else that'll be joining us?"
"Scourge and Fiona looked at each other before looking at Thrash.
"This is pretty much it," Scourge said.
"But I'm sure we can persuade others into helping us," Fiona pointed out.
"So when do we start?" Thrash asked eager to get his revenge.
"Whenever your ready," Scourge answered.
"Good," Thrash said with an evil grin. Back in Albion, Sonic, Tails and Sally arrive to see that Knuckles was successful.
"Well, looks like he did it," Sonic pointed out looking around.
"What exactly happened anyway?" Sally asked.
"Well while you were robotized, Thrash the Tasmanian devil found a way to power up the warp ring and imprisoned Knuckles' people in the twilight cage," Sonic explained shocking Sally.
"But why?" Sally asked.
"Revenge I think it was," Tails answered.
"That's horrible," Sally pointed out as they arrive at Knuckles' location.
"Hey Knuckles, glad to see you did it," Sonic commented unaware of what happened to Julie-Su.
"Not all is won, Sonic," Knuckles pointed out.
"What do you mean my that?" Tails asked.
"They did something to Julie, something horrible," Knuckles answered shocking the Sonic, Tails and Sally.
"What did they do?" Sally asked.
"Lien-Da messed with her mind somehow and turned her against me," Knuckles answered.
"They what?" Sally asked.
"She kept blaming me for leaving her there, I don't know what happened to her, but I want her back," Knuckles pointed out before Charmy flew up to him.
"Sorry to bother you, Knuckles, but something's wrong with the master emerald," Charmy said.
"What is it?" Knuckles asked.
"You might wanna see for yourself," Charmy said. Later at the master emerald which was glowing.
"What is going on?" Knuckles asked.
"You think it might be doing the same thing as before?" Sonic asked.
"That I can't say, but I hope it doesn't, we don't exactly know everyone that it brought back yet," Knuckles answered before a giant beam if green light shot up into the air making a huge portal to the twilight cage with dark legion ships waiting on the other side.
"That's not good," Sally said before the dark legion ships flew through the portal with Lien-Da leading the way. Sonic, Tails, Sally, Knuckles and the Chaotix quickly jumped to action and took down as many ships as they could, but there was too many of them.
"We need to fall back, there's too many of them!" Sally pointed out after slicing a ship in half with her ring blades.
"How did they managed to get back to this world?!" Tails asked before kicking a soldier across the face.
"Everyone fall back to Albion!" Knuckles ordered before they all retreat. Later, Lien-Da's ship lands next to the master emerald and she exits along with Julie-Su.
"Looks like the emeralds are in our possession," Lien-Da said picking up one of the chaos emeralds.
"What's next?" Julie-Su asked.
"We take Albion, half sister," Lien-Da answered. Nearby Scourge, Fiona and Thrash are seen watching the Dark Legion.
"I knew this wouldn't be easy," Thrash said.
"I think we can take them on," Scourge pointed out.
"Then what are we waiting for?" Fiona asked.
"Thrash, you know what to do?" Scourge asked.
"I do," Thrash answered before rushing out into the open and tipped over a tank that was taking aim at him, he then rips the canon of the tank off and whacks several dark legion soldiers with it sending them flying into the ocean below while Scourge runs at high speed and takes down a few dark legion soldiers who were aiming at Thrash.
"Sonic? No, but it does look like him," Lien-Da said seeing Scourge the hedgehog for the first time who lands in front of her and Julie-Su.
"Well, can't say that I've encountered you before," Scourge said.
"Same here, but I can tell that your bad news since your teamed up with that purple dirtbag," Lien-Da said referring to Thrash.
"Who are you calling a dirtbag?" Thrash asked with an angry tone.
"Let him handle this, big guy," Fiona said walking over to Thrash and Scourge.
"Who are you exactly?" Scourge asked.
"Lien-Da, leader of the dark legion," Lien-Da answered introducing herself.
"Hmm, well look I'm busy myself so if you would be as kind as to hand over those chaos emeralds," Scourge demanded before Lien-Da tried to take his head off with her whips, luckily he got out of the way in time.
"I'm afraid we have plans to use them ourselves so back off," Lien-Da demanded before Scourge got up.
"So be it," Scourge said before snapping his finger, Thrash then starts roaring at Lien-Da and Julie-Su, massive sonic shockwaves came from his mouth almost knocking the two over. Lien-Da quickly acts and whips Thrash across the face causing him to hold his face in pain.
"Why you red son of a...!" Thrash shouted in pain before Scourge interrupted.
"Now now, Thrash. Your pretty clever, Lien-Da, those whips of yours are something else," Scourge pointed out.
"You have no idea," Lien-Da said before trying to whip Scourge who jumps out of the way in time and spin dashed into her, Julie-Su acts quick and tries to shoot him, but he was too quick for her and her half sister and they both ended up on the ground while Fiona grabbed the chaos emeralds, out of nowhere though, a dark legion soldier stops her.
"Your not going anywhere, fox girl," the dark legion soldier said aiming his rifle at Fiona, but Scourge spin dashed into him while Thrash helped her grab the chaos emeralds and the three run off.
"They're heading for Albion," Julie-Su pointed out while helping Lien-Da up.
"I don't know if that things capable of going super, but we have to stop him before he does," Lien-Da said.
"But how are we supposed to catch up to that thing? It's as fast as Sonic," The dark legion soldier pointed out while being helped up by Julie-Su, Lien-Da looks at the master emerald for a quick moment and gets an idea.
"I think the time has come to test out a new weapon," Lien-Da said. Back in Albion, Knuckles was seen patrolling the city for any civilians since the city had to be evacuated to shelters. The Chaotix, Sonic, Tails and Sally were escorting people to the nearest shelter, then a echidna soldier runs up to Sonic.
"Sonic, another hedgehog that looks just like you has just been seen outside the city," the echidna said before Sonic ran to the nearest watchtower and saw through the binoculars Scourge, Fiona and Thrash.
"Scourge? He shouldn't be alive," Sonic pointed out before Scourge, Fiona and Thrash pulled out the chaos emeralds, "That's not good."
Scourge floated in the air as the chaos emeralds floated around him, eventually they collide into him as a light consumes him, the light eventually goes away revealing him as a purple hedgehog.
"The city won't last a minute with him in that form. I've gotta warn everyone," Sonic said before running off, but Scourge appears right in front of him.
"Long time no see, Sonic," Scourge said with an evil grin. Meanwhile in the great forest, two figures are seen walking down a path. One was a young female blond human in a pink shirt and blue overalls, pink shoes named Hope, the other was a giant red and black robot with some yellow here and there, his name was E-123 but was called Omega. The two were following the trail hoping to find their way to civilization.
"I still wonder how we ended up here anyway," Hope said walking along the forest with Omega who was looking through previous recordings of what happened.
"Scans indicate that the white light we saw had something to do with it," Omega said.
"We'll have to figure out what it was after we find Shadow and Rouge," Hope said before she noticed a small village nearby, "I wonder what that could be."
Omega scanned the village for any signs of life and finds several.
"Scans indicate there's several signs of life, including two humans," Omega said after scanning.
"Maybe they can help us," Hope said unaware that this was home to the wolf pack nation as she got closer, several wolves ambushed her and Omega scaring her while the giant robot readied for combat.
"Stay close to me, Hope," Omega said aiming at the several wolves that had spears in their hands while a couple were ready to use their fists.
"That's enough!" A female voice shouted, Hope, Omega and the wolves look to see a female grey wolf in a blue leotard, had gold braces and blue shoes, her name was Lupe the wolf and was leader of the village. Lupe walked up to Hope and Omega and took a look at them.
"What brings you here, overlander?" Lupe asked.
"We're looking for someone," Hope answered.
"And who might that be?" Lupe asked.
"He's a hedgehog named Shadow," Hope answered.
"Can't say I've heard of him," Lupe said.
"Well that's a bummer," Hope said.
"And is this robot with you?" Lupe asked.
"Yes, he's my friend," Hope pointed out.
"In that case, everyone step down, they're not with Robotnik," Lupe pointed out before the other wolves stepped down as ordered.
"Thanks," Hope said.
"Your welcome. What's your name by the way?" Lupe asked.
"Hope, Hope Kintobor," Hope answered.
"Well, Hope, welcome to the wolf pack nation," Lupe said welcoming Hope to her village, her and the young human walked into the village where they settled down.
"I hope Shadow Finds us soon," Hope said. Somewhere far from the village, two Mobians were seen walking through the forest, one was a male black hedgehog with red stripes, and a white patch of fur on his chest. He wore white gloves and shoes that matched the color of his quills and fur, his name was Shadow and he was accompanied by a male white bat with a black jumpsuit with white gloves and boots with a bit of pink. Her name was Rouge and was Shadow's partner. They were both roaming the forest looking for Hope.
"I know that Robotnik had something to do with Hope's disappearance," Shadow pointed out.
"Probably, but if anything, that nephew of his named Snively probably has her," Rouge said making suggestions as to where Hope was.
"If he does, I'll make him regret laying his hands on her," Shadow said before spotting a village nearby.
"Looks like we've got locals," Rouge said as they snuck closer to find activity around the village.
"Doesn't seem like any of our concern," Shadow said before one of the patrol spots him and Rouge.
"Don't move!" The patrol said aiming his spear at them, Shadow stands in front of Rouge, protecting her, the rest of the wolf village noticed and rushed over to see what it was.
"What have you found?" Lupe asked.
"I found these two sneaking around," the patrol answered.
"We were going to leave," Shadow pointed out.
"Who are you anyway?" Lupe asked.
"Shadow, Shadow the hedgehog," Shadow answered making Lupe realize something.
"You might wanna come with me back to the village," Lupe said before walking back to the village with Shadow following her, they entered the tent to find Hope and Omega.
"Hope!" Shadow exclaimed as Hope jumped onto Shadow and hugged him, "when I realized that light erased you from existence, I thought for sure that you were gone forever."
Shadow and Hope hugged each other for a few seconds before letting go as Rouge walked in.
"I guess that wraps up everything," Rouge pointed out. Back with Sonic who was flung into several buildings by Super Scourge.
"You have no chance, Sonic, I made a mistake last time I had the edge on you, now I'll destroy everyone you love, but first I need to help eradicate these echidnas," Scourge pointed out before throwing Sonic at a building knocking him out cold, he then races over to Thrash who have some echidnas cornered.
"I have this under control," Thrash pointed out.
"Well I have nothing better to do since I knocked Sonic out," Scourge pointed out.
"Fine, but leave most of them for me to handle," Thrash demanded before Scourge charged up an attack.
"Don't worry, this will hurt a lot." Scourge said as the attack reaches full charge.
