Obsidian: Now, this one could be hard to follow.

Sonic: A lot of them are hard to follow!

Shadow: What makes this one any different?

Obsidian: This one has...you're just gonna have to read it!

Mobian Excursion

"One question, Obsidian," Hunter said as he came onto the bridge, "why are we going to Mobius?" "For one," Obsidian replied, "I'm pretty sure there's a Spirit Key on Mobius, and I know for certain that the Planet X Key is."

"And you know this how?"

"I'm the one who hid it there."

(Duel Academy)

Demon was lying in wait for the heroes to show up, when Darkstone contacted him telepathically. "Demon," he said, "you must take my soldiers and head for Mobius." "Why should I?" Demon asked, and then clutched his head in pain. "I GET THE MESSAGE!!!!" he shouted, as he gathered the Apocalypse Forces, symbiotes, and Waspinator. "Ultimatum," he said, "Take us to Mobius." Ultimatum opened a portal, and the villains walked into it.

(Mobius: South Island)

The New Ark appeared over Green Hill Zone and touched down. "Okay," Obsidian said, "who's coming along this time?" Shadow, Tails, Knuckles, Amy, Julie, Manic, Sonia, and Prime stepped up. "Where's Sonic?" Obsidian asked.

Sonic was in his room, with the door locked. Obsidian just makes the door disappear and walks in. "You're coming, right," he said. "Wrong," Sonic replied. "I'm not asking," Obsidian told him. "Fine,' Sonic said, not even bothering to argue.

As soon as they left the ship, they saw a Flicky carrying the Spirit Key. Obsidian waited for the bird to drop it, and picked it up. "Okay," Manic said, "where's this Planet X Key?" "I gave it to…" Obsidian started, "now I know why Sonic didn't want to come! He and his siblings are royalty here!" Everyone else was shocked. "He's right," Sonic added, "our mom's the queen of Mobius."

"Let's split into two groups," Obsidian said, "Shadow, Knuckles, Amy, and Julie will search for the other Spirit Key, while the rest of us go talk to Queen Aleena."

(With Group 1: Shadow, Knuckles, and the Rose Sisters)

Shadow checked Emerald Hill Zone first. If this music wasn't giving me a headache, he thought, I'd enjoy it here. He then noticed a switch. It was set to "vs", with "normal" being the other setting. Shadow switched it to "normal", and the music changed. "That's better," he said, as the group pressed onward.

(I felt a little random right there)

The group passed through Emerald Hill Zone, and got to Chemical Plant Zone. It was a little worse for wear, but they could still pass through with little difficulty. Once they found the Spirit Key, Venom and Carnage appeared.

(Play "Crawling" by Linkin Park. I picked this one because it seems to fit the symbiotes quite well)

Shadow sent Chaos Spears at Carnage, who dodged. Knuckles attacked Venom with a Thunder Arrow, stunning him. After recovering, Venom charged at Knuckles, arms extended, and clawed at him. Knuckles punched the symbiote away, and then threw a piece of the machinery at him.

Carnage morphed his right hand into a scythe, and his left hand into a tentacle, and charged at Shadow. Shadow avoided the attack and attacked with lightning. Carnage screamed in pain, and then laughed psychotically when the attack was over. Shadow then attacked again, but Carnage avoided the attack this time.

Venom sent webs at Knuckles, who barely avoided them. The red echidna then summoned a boulder and threw it at Venom, who smashed it with his enhanced strength. Venom then grabbed a large pole and started to attack with it. Amy doused Venom with water, not really doing anything to him.

Carnage swung his axe-hand at Shadow again, and missed once again. "If we cannot kill you," he said, as he grabbed Julie with his tentacles, "I guess we'll just have to kill your friends first." Shadow entered his Darkspines form and severed the tentacles with a strong blast of electricity. It kept going and hit some pipes, making a loud noise. Venom and Carnage seemed to go crazy when they heard the noise. "That's it," Shadow said, "guys; make as much noise with the pipes as possible!"

Amy and Julie started hitting metal with their hammers, and Knuckles started banging pipes together. The symbiotes started to slide off of their hosts. Once they fell off completely, Dark Shadow appeared, and drew a pair of swords. He went over to the symbiotes' hosts and killed them. Venom crawled off, while Carnage charged at Dark Shadow. The clone welcomed the symbiote, and let it bond with him. He was soon in what looked like a crimson suit of armor, which appeared to melt, covering his entire body. He now had a manic smile, bearing sharp teeth, white eye-patches, and erratically-moving quills. He let out a psychotic laugh, and said, "We are now SHADOW-CARNAGE!!!!!!!!"

(With Group 2: Obsidian, Sonic, Manic, Sonia, Tails, and Prime. If the song's still playing, read no further until it's over.)

(Play "His World", whichever one you want)

Obsidian warped the group right to the castle. "I'll wait here," Prime said, and he transformed. The rest of the group walked into the castle.

"So," Sonic started, "what's the deal with the Planet X Key?" "You know how the Cyber Planet Keys are pieces of Primus's power, right?" Obsidian replied, "Well the Planet X key is a piece of Unicron's power. You see, both of them sealed the vast majority of their power into the Omega Lock. They created the Keys for if they ever needed that power again. The Planet X Key's Guardian was killed by one of Unicron's previous servants, before Darkstone. I managed to escape with the Key, and hand it to the royal family of Mobius. However, this servant tracked me down. I managed to kill him, but he used the last of his power to seal me in time, and erase my memory. It was Hunter who released me from the seal."

As Obsidian's story ended, they came up to the door to the throne room. It opened, revealing Aleena, Queen of Mobius. "I was wondering when my children would show up," she said. "Your Highness," Obsidian said, bowing, "we require the Planet X Key." "Why you would need it, I wonder," Aleena replied. Obsidian decided to enter his Human Form. He has a slight tan, sunglasses, a white shirt, blue jeans, Air Shoes, and a black trenchcoat. "I am the one who gave it to your great-great-great grandfather." "Very well then," Aleena replied, opening a secret chamber, housing the Planet X Key. Obsidian grabbed it.

Shadow, Knuckles, and the Rose Sisters burst in. "We've got the last Spirit Key," Shadow said, "but we have a problem." Shadow-Carnage burst into the castle. "Now you shall all die!" he yelled, before being hit by Prime's ion cannon, sending him flying. "We have to move, now!" Prime called to the group. The Apocalypse Forces were on the other side of the drawbridge, along with Essence, the dark clones, and Waspinator. Shadow sent Chaos Spears at his clone, who dodged. The attack kept going and hit Waspinator, blowing him to pieces again.

Obsidian drew Lightbringer, and charged at Ultimatum, who avoided the attack. Sonic spin-dashed at War Machine, who countered with missiles. Sonic was sent backwards, but wasn't seriously hurt. Knuckles threw a boulder at Hydra, who slashed it in half with her scythe. Obsidian attacked the bridge itself, but it resisted the blow.

Light, Hunter, and Jaden caught up with the group. "You shouldn't be here," Obsidian told Light, "You're still injured!" "He looks fine to me," Demon said, standing behind Light, 'in fact, he looks good enough to re-merge with!" He put his hand on Light, and sent his power into him. Demon vanished after a few seconds, and Light's wounds were completely healed, but he then started to change.

Light's body absloutly changed into a monster. The Hollow mask fully engulfed his face. He has devil wings. He has a lizard tail, sharp claws, dragon feet, spikes on his left shoulder and back, long white hair, colored black and white.His eyes are black and yellow. "I call this form," He said, but in Demon's tone, "Hollow Mode!"

Obsidian decided that enough was enough.

"DIMENSIONAL EVOLUTION!!!!!!!!!!"

He entered his Knight Mode, and prepared to fight.

Shadow: Why did my clone get Carnage?

Sonic: And why's Light evil?

Obsidian: I didn't write it!

Silver: Next Time: The Battle of Mobius!
