Chapter 19: Day 18: Dark Sonic Unleashed.

The five royal hedgehogs were currently staring down the enemies that had been recruited into the Eggman Empire after Eggman had successfully conquered 99% of the world. They were thankful the Oracle of Delphius didn't tell of a prophecy for this takeover, but were worried that he did tell them that there was a chance they might lose. They had been tracking Eggman for the past five weeks while helping the Resistance weaken Eggman's empire and had finally caught up with him in a ruined city after making excellent progress, along with a few unwelcome guests. Sonic glared at the Deadly Six, Metal Sonic, Shadow and Chaos as they stood on top of a destroyed building.

"I can understand everyone here except you, Shadow. Why are you siding with Eggman?!" Sonic asked.

Shadow smirked, "Because, this is as good a chance as any to prove to myself that I'm stronger than you, Sonic!" Shadow said before Eggman floated above them in his Egg Mobile. He let out a laugh as the Hedgehog family glared at him.

"I'm so happy right now! My dream is finally going to come true! Now, me and everyone else here can have our revenge on you, Hedgehogs!" he yelled.

"Enough talk, Fatty Lobotnik! Are you going to fight us or not?!" Sam yelled before Zavok ran over and punched him in the stomach, sending him to his knees and making him cry.

Sonic glared furiously at the horned Zeti, "This time, you've gone too far, Zavok!" he shouted as he ran at Zavok and the two of them got into a fist fight that resulted in the rest of the Deadly Six joining in, giving the Zeti an unfair advantage. Sonic held his own, but was worried about the rest of his family as constantly glanced and saw them struggling. Sonia and Sam were firing laser blasts at Metal Sonic, but the robotic hedgehog wasn't even fazed as he opened his fingers and shot bullets at them which they managed to narrowly avoid. Shadow was going head to head with Manic, who was trying to strike the black and red hedgehog with earthquakes, but Shadow would easily avoid them by using Chaos Control. Aleena was trying to gain an advantage over Chaos, but every time she would try an attack, he would just reform to avoid it before he formed into a bull and rammed into Aleena full force, knocking her through rubble and heavily injuring her before she fell unconscious after slamming into a wall.

"MOM!" her children cried before they were all heavily injured by the enemies they were fighting. Sonia, Manic and Sam were knocked unconscious just like Aleena, but Sonic managed to avoid a blow by Zavok.

The villains all laughed triumphantly, "Why don't you just do the smart thing and give up, Sonic? You're defeated!" Zeena said. Sonic glared at them before he looked at his family.

"I. Am Not. Going To Let…" Sonic started, a black aura surrounding him, before he shouted, "YOU SCUMBAGS GET AWAY WITH THIS!" The black aura exploded around him. When it cleared, Sonic's entire body was covered with pure black energy, his quills stood up like Super Sonic's, his eyes were pure red with no pupils and he was as muscular as the Werehog. Sonic's Dark Super Form had just been taken to a whole new level. This frightened the bad guys enough that Zeena and Eggman were screaming in fright and even Shadow and Zavok were sweating as the angry hedgehog made slow steps towards them.

"What's that old saying about times like this?" asked Zor.

"That when the going gets tough, the tough get going?" Zazz asked.

"If we get going now, we might can make it back to base in time for dinner." said Zomom.

"No way. Deadly Six, attack!" Zavok ordered. The six Zeti leapt at the hedgehog, only for him to grab each one of them by the throats and slam them into the ground repeatedly before beating them up and sending them flying with a powerful punch. He then turned on Chaos, who he defeated easily by reaching through his water-like body and squishing his brain, making him explode. Metal Sonic attempted an attack from behind, but Sonic grabbed him at the last second and smashed him into the ground, ruining him greatly before breaking his hand through Metal Sonic's chest and pulled out some of his wires, rendering him powerless. Shadow leapt into the air and launched multiple Chaos Spears at Sonic, only for him to knock them away. Shadow attempted to attack Sonic with a combo attack, but try as he might, he could do him no harm. Shadow jumped up, attempting to use Chaos Blast, only for Sonic to punch him in the eye by extending his arms, breaking his concentration and giving him a chance to leap up in the air and grab Shadow. Struggle as he might, Shadow couldn't break free. After Sonic beat him severely and tossed him far into the distance, he glared at Eggman, who was sweating and shaking with fear. Sonic leapt onto a pile of rubble and advanced towards Eggman.

"Stay baaaack!" Eggman shouted before Sonic grabbed him by the collar and was about to beat him when he heard someone call, "Sonic, stop!" He looked and saw his family, who had been healed by soldiers. He calmed down and his dark form faded. When he returned to normal, he smiled at his family, who smiled back.

He then turned to Eggman and said, "Game over, Egghead." before he brought his face closer to him, "But, mark my words. If you hurt my family like that again, you're going to suffer, and when you beg me for mercy, I'll stare into your eyes as I crush you." before he tossed him to the ground.

The blue hedgehog then walked over to his family with his head down, "I'm sorry you guys had to see me like that." he said. Aleena rubbed his head with a smile, "It's OK, sweetie." she said, making Sonic smile.
