Dark Sonic
Mobius: Angel Island
The heroes and villains are struggling an intense battle.
"Take this!" Knuckles says as he assaults Metal Sonic, who just sidesteps it.
"Inaccurate." Metal Sonic says as he knocks Knuckles back to the altar.
Sonic gets back up. "Forgot about me?" He asks.
"Sonic the Hedgehog is still not finished. Further assaults required." Metal Sonic says, as he knocks Sonic to the altar.
"Oh no, Sonic!" Amy says as she runs off to Sonic.
"Any refusal to subject to the master shall be eliminated." Metal Sonic said.
Phi flies after Isabella and Ginger.
"Look out! Duck your heads!" Baljeet warns them, just as a missile is headed towards them.
"Thanks Baljeet." Ginger said.
"Weaponry no longer an option, switching to close combat." Phi said.
Phi tries to ram into the two girls, but they dodge and shoot him with baseballs.
Shadow and Shadow Android were launching attacks at each other.
"I'm the ultimate. You cannot defeat me." Shadow Android said.
"I don't think so, we both may be artificial beings, but at least I'm an organic life form." Shadow talks back.
Meanwhile Amy is watching over Sonic.
"Don't worry Sonic, you'll be fine." Amy assured Sonic.
But then she gets knocked to the head by Phi.
"Amy!" Sonic shouts as Amy crashes into a tree.
"Target hit." Phi replied.
Sonic suddenly stands up.
"Impressive endurance, but that will not last forever." Phi said.
"Why you." Sonic says angrily. "You're gonna pay for that." The fake Chaos Emeralds start to react to Sonic's anger. A dark light surround Sonic, and his fur turns to black, his eyes are now completely white, and his skin turns grey, and now surrounded by a dark energy.
"An unexpected transformation caused by a sheer force of anger. No matter, the master's orders must be carried out." Phi says in response to Sonic's transformation.
"Oh, shut up with the master's orders! I will destroy you scrap metals." Sonic said.
"You alright Sonic?" Phineas asked.
Sonic doesn't hear him, and instead, he starts attacking Shadow Android and Metal Sonic, while grinning maliciously, and seemingly taking pleasure in doing so.
"I've never seen Sonic this angry before." Adyson said.
"Me neither, but there's someone who witnessed this." Tails said.
"Who did?" Adyson asked.
"Eggman, according to him, in order for that to happen, he needs more than just fake Chaos Emeralds, Sonic also needs to experience enough anger, which will turn him into Dark Sonic, who is way more violent than normal Sonic." Tails explained.
"No kidding." Adyson said.
"He wasn't the only one there, Rouge and I were also there." Shadow said.
Dark Sonic's got the three robots cornered.
"Retreat, Shadow Android and Metal Sonic, retreat to Earth and help the master." Phi ordered.
"But what about you?" Metal Sonic asked.
"I will deal with Sonic and his friends, you should help the master." Phi said.
"Understood." Metal Sonc and Shadow Android both say. "Chaos Control!" And they both disappear with a flash of light.
Phi turns his attention towards Dark Sonic. "Priority One: Sonic the Hedgehog." Phi said.
"Let's see you try." Dark Sonic challenged.
Phi speeds towards Dark Sonic and rams into him multiple times, but Dark Sonic isn't fazed.
"Failure to damage Sonic, the odds are not in my favor." Phi said.
"Well, now I'm about to end you." Dark Sonic says as he rams into Phi.
"Systems damaged beyond repairs, all systems shutting down." Phi says as he shuts down, then explodes.
"Sonic!" Tails call out to him.
Dark Sonic returns to his real self.
"Hey Tails, what's up?" Sonic asks.
"Metal Sonic and Shadow Android went back to Earth." Tails informed. "We have to follow them."
"All right, time for a final showdown." Sonic said.
"Yeah!" The rest of the heroes said in agreement.
"Chaos Control!" Sonic and Shadow say, and a bright light engulf the altar, and the heroes disappear.
Thanks to his transformation into Dark Sonic, Sonic is able to destroy Phi. Metal Sonic and Shadow Android retreat back to Earth. Can they destroy the remaining robots and defeat Eggman Nega? To be continued...
