At Eggman's base, Sonic, Amy and Tails was now facing Crimson the Echidna inside the toxic chemical room.
"Crimson! It's not very you to work with Eggman. You decided to join him?!" Sonic asked angrily.
"Well working alone was not as quite much fun. So I joined your nemesis" Crimson said.
"Well we have taken you down once and we will do it again!" Sonic got in front of his friends. But Amy was concerned he'll get hurt.
"Sonic, be careful" Amy said.
"Have faith in me, Go get the anti virus from Eggman while I deal with Crimson" Sonic tells them before turning to Crimson.
"But Sonic..." Amy was cut of by Tails.
"Lets just go, hurry" Tails grabs Amy's arm and ran away with her.
Crimson grins evilly as he raised his claws.
"Less talk more fight!" He shouted and charges at Sonic, but Sonic jumps just above him and kicks him down. He then spins his feet rapidly and spindashes hard at Crimson hitting him in the gut and caused him to crash onto near vats of the chemicals.
"Careful Sonic, these chemical are toxic unstable artifical chaos energy" Crimson said waving his finger.
"So Eggman wants to create artifical chaos energy? Well ain't gonna happen!" Sonic glared. Then the two jumped up and clashed at each other, after that they landed on each side. It because quiet for a few seconds until Sonic was shown having a slash on his cheek. Crimson then turned and chuckled, having some of Sonic's blood on his blades. Sonic then growls angrily and turned into his dark Sonic form.
"Alright! C'MON!" Dark Sonic charges at Crimson punching him right at a steam pipe, the impact broke the pipe slighty and steam came out. The echidna got up and groans in pain.
"Ouch, That almost hurt" Crimson said. Dark Sonic growls louder and attacks Crimson but his blows were blocked by the echidna.
At the hallway, Amy and Tails were closing in to Eggman's laboratory and by the help of the piko piko hammer Amy destroyed the turrets in the hallway.
"Good job there Amy! You are doing great!" Tails said. Amy gave a thumbs up like Sonic and then destroyed the last turret avoiding it's laser beams.
"Gotcha!" Amy cheered when she landed on the other side.
"Now lets get the anti virus" Amy headed to the laboratory door with Tails. When they got to the lab, they saw Doctor Eggman waiting there expecting them both.
"So you have come to get the anti virus huh?" Eggman asked them.
"Yes, to reverse the effects of Cyo's virus permanently! Why choose him?!" Amy asked.
"I figured that since he is part machine he is vulnerable to viruses, so I decided to turn him into my perfect weapon. I know that you wouldn't actually hurt him so he can have the upper hand by knowing your moves" Eggman explained to both of them.
"So that's why? And those canister with toxic chemicals?" Amy asked.
"That is artifical chaos energy. They are indeed toxic for any organic beings, I have tested it on rats and they just grew crazy" Eggman said.
"Artifical chaos energy. Hmmm, Well it's gonna take a while for it to be stable if I'm correct" Tails said. Eggman nodded.
"Now hand us the anti virus" Tails said.
"Never!" Eggman grabs a USB stick with a cross on and gets into a escape elevator to the floor. Tails and Amy tried to catch him but too late.
"We got to get Eggman before he escapes!" Tails said.
"Check were he's going!" Amy said. Tails clicks his device to see the map on the base and sees Eggman's movements.
"He's heading to the hangar" Tails said, running out of the lab with Amy.
In the chemical lab, Crimson was desperately trying to attack the now normal Sonic but misses the quick hedgehog every time, and he just grew more angry.
"HOLD STILL DAMN IT!" Crimson yelled.
"You know Crimson, you should get anger management" Sonic taunts him.
"NAAAARGH!" Crimson slashes at him but only managed to slice a Eggbot in two. He then saw Sonic stand up near a vat of toxic artifical chaos energy.
"Hehehehe, I got you now!" Crimson leaps at Sonic and strikes his blades at him but then accidently strikes his claw at the vat. He then struggled to pull his blades out of the vat.
"Well if you excuse me Crimson I got a doctor to deal with" Sonic smirks and runs away. Crimson grew angrier as his blue eyes goes bloodshot and he pulls his blades out of the vat, his anger was turned into shock when he saw the holes he made spew out the chemicals right at him.
"AAAAAARGH IT BURNS! AAAAAAAAAAHHHHH!" Crimson screamed so loud it could be heard in the base. Sonic heard it but then focused on finding Eggman and his friends. But he was too late to know that something is happening to Crimson, the echidna's body began to glow in and out over and over again until he began trembling.
At the workshop, Shadow was with Nebula in the kitchen having coffee while the others watched TV. Fairy soon joined them and had a cup of tea in her hand.
"How is Cyo doing?" Shadow asked Fairy.
"He's sleeping right now, so no worries" Fairy said.
"Good. Now I hope Faker, Amy and Tails will be back in time" Shadow said drinking his coffee.
"I know they will. Eggman always fail remember" Nebula said.
"Yes. This time he almost succeded by turning Cyo into his puppet" Shadow said. He then looked out the window into the sky were the moon was visible.
"Beautiful isn't it?" Nebula asked.
"Yes it is my little nova star" Shadow said smiling.
