A/N: hello Freedom Fighters! I loved Sonic Underground since I was a kid. I always wonder why they didn't have a dad or so and why they never mention him. But after seeing a picture of a green king hedgehog, it made me wonder.... but anyways, I hope this will entertain you awesome fans out there. Enjoy a family story together!

In the darkest land in Robotrophillis, all Swat bots were watching the grounds of Dr. Robotnik's evil lair. Ever since Robotnik has taken control of Möbius, barley anyone has tried to fight him or his robots. The only ones who knew how to make them have faith and pride was none other than Queen Aleena's children, Sonic, Sonia, and Manic. Many families were ruined and destroyed but their fathers were lucky to go into the Möbius world to stop them. But today, the three little hedgehogs discover something of what starts ever single family: a father of their own.
In the lair of Dr. Robotnik, his little dog slaves, Sleet and Dingo, were searching through flies to find something useful to destroy Queen Aleena's children. So far, nothing has come past them.
Sleet was mostly taking a look at Sonic and Manic's. The most he's learn is that Sonic has always gain weight every year and Manic was a child of a thief. Dingo, on the other hand, was looking into Sonia's file, drooling at a picture of the beautiful pink hedgehog.
BAM!
"Ow!" Dingo rubbed the mark of his head being hit.
"Will you stop being a bafoon for once?" Sleet said with evil eyes and tone.
"But Sonia is so pretty." Dingo said looking back at the picture.
"And you're ugly." Sleet reminded him.
No matter what, Dingo will always have his crush on the beautiful Princess Sonia.
"Silent you fools!" Robotnik yelled as he walked into the room. He walked to the pile of flies and grabbed one which had Queen Aleena's file. Her picture showed her beautiful smile. He was disgusted by that picture. "I'll find your little brats Aleena..." He said with an evil smirk spreading across his face. "... And you will be gone forever!" He then used all his arm strength to tear the file into two.
"Don't you worry your greatness." Sleet said with fear in his voice. "We'll find them... somehow."
"Yeah. It's not that hard to find one big family of hedgehogs." Dingo said.
"That is very true." Robotnik said as he put the torn up file in the trash. "I mean, it was definitely easy when I got rid of Maximum."
"Who's that?"
"You idiot." Sleet smacked Dingo's head once again.
"What? I never heard of him." He said rubbing his head.
"Of course not you fool." Robotnik said. "No one is suppose to know, or remember Maximum."
"Well who is he?" Dingo still don't understand.
"He use to be the king when Mobodoon was always existed. But I got rid of him. He's no longer here anymore."
Still lost. "I thought Queen Aleena was the ruler of Mobodoon."
"Yes that's true moron." Sleet said. "But that was a long time ago."
Robotnik could even remember that day when he got rid of him. But as he started to remember, he wondered...
"What is today?" He asked.
"It is a Tuesday sir." Sleet said. "The fifteen."
Robotnik gasped. He couldn't believe. The day went by so fast. Now he began to worry. "Sleet! Dingo! I want you two to go and find Dimension S and see if he is still remaining there!"
"Um, where's Dimension S?" Dingo said.
Robotnik only sighed annoyed. Then he looked at Sleet and said "Sleet, make sure to explain to the bafoon what Dimension S is and why you must go once the moon is full."
"No problem sir." Sleet said. "And if we find him in Dimension S?"
"Destroy him."

At another part of Möbius...

Running through the cold and wintery snow, it freezes any living thing with is cold wind. But with the three hedgehogs running through it with their fast brother, try were able to survive. They even had winter clothes on. There was only one problem they were having.
"Dude, are we there yet or are we lost?" Manic asked his brother.
"Relax." Sonic said still running. "I know for a fact that we're almost there."
"Well what makes you think so?" Sonia asked.
"Just my guy growling."
"Well you guy better hurry it up." She said. "I'm freezing being under all their snow."
"I think we're lost still." Manic said.
The winter was not alway their favorite season. Especially Sonia. But she always had the bet wardrobe for it.
"Don't worry guys. I know what I'm-"
BAM!
They pops their heads out of the ground of snow and rubbed it as pain was in their heads. Some ride that was.
But Sonic's smiled appear and he said "See? We're here!"
"Hooray..." Manic said unpleasant.
After a few minutes of digging their bodies out of the snow, they walked around the giant rock they were facing. Soon they found an opening and walked in feeling a bit more warmer and better. They continue to walk through the cave and found the beautiful home of the Oracle of Delphis. (Not sure if that's how you spell it. If it ain't, please tell me)
"Just me, or the Oracle knows how to keep a warm place." Manic said rubbing his arms for more warmth.
"I hope that is a compliment." A voice said so sudden.
They each jumped from the random voice. But then they were facing the Oracle as he appear from a beautiful turquoise light. "Welcome back young hedgehogs."
"Hey ya Orc!" Sonic waved, happy to see him. "You got any chili dogs on ya?"
Soon, the Oracle used his magic to his table to reveal a giant plate of chili dogs.
Sonic began to drool as he smelled the delicious dogs. "Ooh! You could have said yes, but I'll take magic for an answer." He ran to the table and began to eat.
Sonia only wanted to puke as he watched her brother eat. She and Manic went for the table as well and the Oracle say with them.
"Oracle," Sonia said to him. "We're here because there was a signal of finding mother."
"That is correct." Oracle said with a we smile.
"You mean we're close to finding mom?" Manic asked.
"What do you think?"
"I'm thinking these are the best chili dogs ever." Sonic said with a mouth full.
"No manners huh Sonic?" Sonia said.
Sonic only nodded and continued to eat.
"If we're close to finding mom, we'll be able to stop Buttnik." Manic said looking very happy.
Oracle chuckled. "Very likely."
Sonic then began to realize something about the Oracle. "But...?"
"But-"
"Knew he was gonna say it." He are another chili dog.
"But so far, there is one thing that can help reunite with your mother." He said.
The three hedgehogs look stunned. There's something else they need to search in order to find their mother. "What is that?" Sonia asked.
"Today is the fifteen, which means the moon has finally rise for tonight." Oracle said.
"Oh, so we need to kidnap the moon?" Sonic asked.
The Oracle only chuckled. "Nope. But the year an time and finally arrived for Dimension S to be open."
"What's Dimension S?" Sonia asked.
"It is another part of our dimension that is exactly like ours, only with different people."
"Everyone is ugly in Dimension S?" Sonic asked.
"Not exactly. Everyone is actually very lovely as the ruler of Dimension S is finally able to reopen it. But he has no way to make back here to Möbius."
They still didn't understand. "Is he evil?" Manic asked.
"Nope. Very nice and caring, just like your mother."
"You mean mom might be there in Dimension S?" Sonic asked.
"What do you think?"
They only stared at each other. They weren't exactly sure what he is saying.
"There is the reason why the prophecy said the consul four." The oracle said. "All because the fifth went missing and now you can be more powerful, one he returns."
Still were the hedgehogs lost. "Uhhh..." Sonic pointed it out to him.
"You see that mirror?" The Oracle pointed to the mirror that was hanging on the wall.
The hedgehogs look back and were surprised they never noticed it until now. They looked back at the Oracle and nodded.
"Well that mirror is the gateway to Dimension S." He said. "It can be open for only three days while the full moon remains out. But on the third day, the gateway will close and their will be no way to escape it."
"What are you saying Orc?" Sonic asked.
"You three must go through the portal, search for the one known as King Maximum, and bring him back before the third day comes and the gate way closes."
"Who's King Maximum?" Sonia asked.
"That is for your three to figure out."
They wonder if this was such a good idea. Going to another Dimension and look for some random king. What was the reason? How can he be the answer to stopping Robotnik along with their mother?
But if the Oracle says he could be the key to finding their mother, might as well understand why they must go.
Sonic stood up with a smile and said "When do we head out?"
