Mobotropolis

The Battle Bird Armada were bombing the city.

"Attention citizens of Mobotropolis, surrender to the Egg Army or else face torture beyond your worst nightmares!" XV said from his ship. Sonic ran out of Castle Acorn. Sally followed him but couldn't catch up.

"Where are you going?" she yelled.

"I have a friend who can help me fight these guys!" Sonic yelled.

Tails' Workshop

Sonic ran up to Tails door and knocked on it. Tails opened the door.

"Sonic? You know you can just come in, right?" Tails asked. "Especially if an Armada attacking!"

"About that…" Sonic said. "Think you can fly me up there in the Tornado?"

"Why?" Tails asked.

"Because I promised the King I would protect this city and planet!" Sonic said.

"You're crazy…" Tails said.

"C'mon, Tails." Sonic said. "We'll be heroes if we do!"

"You're not going to give me a choice, are you?"

"Nope."

"I'll get the Tornado ready," Tails sighed, walking back inside.

Castle Acorn, Throne Room

King Acorn sat on the throne, ordering soldiers and air patrol to start defending. Sally ran in.

"Daddy, please let me help!" Sally asked. "I brought these Ring-Blades for a reason!" She activated one of them.

"No, out of the question." the King said. "Too dangerous!" Nicole appeared in the room.

"Sire!" he yelled. "Sally is a princess and as a princess, it's her job to protect this kingdom, no matter the risk!" The King sighed.

"You're right, Nicole," the King said. "Sally, you may join the fight outside… but please, return safe to me." Sally nodded and ran out.

Above Mobotropolis

Sonic and Tails, in the Tornado, flew around the ships, shooting the cannons.

"How are we going to drive them out, Sonic?" Tails asked.

"Simple, we take down their leader!" Sonic said. "Which is that one, I think." He pointed at the biggest ship. "Aim for the cockpit!"

Battle Bird Armada, Cockpit of the Main Ship

XV was watching as his troops were attacking the city, while he yelled threats into the microphone.

"Just give up or they'll be no survivors!" he yelled. The glass around him shattered as it was hit by bullets from the Tornado. Sonic jumped in, taking out the pilots of the ship.

"You!" he yelled. "Stop this attack, or else!"

"Or else what, rodent?" XV asked. Sonic homing attacked him, making him lose his balance. Sonic then ran over to the control panel and turned to ship towards another one, trying to make them crash.

"St...st...STOP!" XV yelled. "Are you trying to kill us both?"

"Why are you here?" Sonic yelled.

"By order of Dr. Robotnik…" XV said as he put on a jet pack and got out the microphone. "Retreat! Retreat! Fall back! Fall back!" He activated the jetpack and flew away as Sonic jumped out just as the ship crashed into another ship.

Mobotropolis

Sonic landed right next to Sally, who was tearing apart Pursuit Drones.

"That was a close one, up there!" She said.

"I made a pretty cool entrance, didn't I?" Sonic laughed. "The Battle Birds are retreating."

"Good." Sally said. "Any information about them?"

"Yeah…" Sonic said, slowly. "Turns out, Robotnik ordered the attack."

"Ro… Robotnik?" Sally muttered. She froze in place, unable to move.

The Battle Birds got the message of their retreat and flew away. Tails and the Tornado landed and he ran up to Sonic and Sally.

"Sonic! Did you see me?" Tails yelled in excitement.

"You did great, buddy," Sonic said. "Sally, this is my best pal, Tails."

"What?...Sorry," Sally said. "I was just… thinking about… never mind…"

"Never mind what?" Sonic asked.

"It's an honor to meet you, princess," Tails said, holding out his hand.

"It's nice to meet you two," Sally said, shaking his hand. "Sonic, my father needs to know this, this second!"

"No problem, Sal," Sonic said.

Castle Acorn

Sally, Sonic and Tails made their way to the castle and informed king about Robotnik.

"Mmm… this is a problem…" the King said. "Robotnik did say he would be back for his revenge…"

"But if he wanted revenge, why did send someone else to do the work, instead of himself?" Tails asked. Nicole appeared in the room.

"Because he wants to soften us up…" she said. "That attack was to merely destroy our defences and equipment. If the doctor attacked now, we have nothing to defend against…" The room went silent.

"Then I'll just bring the fight to him!" Sonic said. "I will protect this planet from Robotnik's evil!"

"My, my, do you ever stop being heroic?" the King joked.

"But… Going to Robotnik, alone, is suicide!" Nicole said.

"Then I'll bring a team!" Sonic suggested.

"And I'm apart of it!" Tails said.

"Me too!" Sally said.

"Very well, Freedom Fighters, you will find and destroy Robotnik before he destroys us!" the King ordered.

"But they'll need a bigger team…" Nicole said.

"Then you're apart of it as well!" the King said.

"What?" Nicole yelled.

Mt. Mobius, Veg-O-Fortress

Snively walked into Robotnik's room, with a tablet.

"Sir, I have just gotten word that…" Snively said.

"I know…" Robotnik said, sitting in his chair, looking at his monitors. "But know matter… they have already lost the war before it begun! This world… belongs to me!"
