Chapter 1- Introduction- Assault on Robotropolis

Somewhere outside Robotropolis 11:00 PM

The Rain poured down hard. Very hard. Between the dark night and the rain, visibility was minimal.

"This is not the kind of weather to be in when fighting a war against the forces of darkness," Tails thought to himself as he stood in the middle of the open battlefield. It fits the mood, though."

"I hate the rain," he muttered to himself. He wore a black trench coat as his protection from the downpour.

A bolt of lightning streaked through the night sky, illuminating the area to near broad daylight for a millisecond. A resounding thunderclap that shook the heavens followed immediately.

"And I hate thunder and lightning even more," Tails said as he pulled his coat closer to himself. He knew he really should've kept moving, instead of standing still, but there was so much on his mind that he couldn't help but reflect on all the events leading to this war.

"I never meant for it to happen this way."

"No. What am I talking about? I totally saw this coming. Right when I got back to Mobius..., I could've sensed it would lead to this."

Too late now. So many people are dead. My friends...," he scanned the field around him, the scene lit up by the lightning. The land was littered with corpses. Skulls of humans and mobians were strewn across the field. Everywhere he stepped, there were bones.

"When I was a baby, I lost my family." The thunder boomed as if it were responding to his thoughts.

"When I was four, I fought alongside Sonic for the first time. Robotnik shot me out of the skies, then."

"When I was eight, I fought Chaos. I built a spaceship, saved the galaxy, and killed my love." The battlefield was filled with the sounds of metal clashing against metal, bullets and lasers being fired, and things exploding. Tails was too absorbed to pay attention.

I'm twelve now. I guess this is what I have to deal with at this age. This was all my fault. It's up to me to set things right."

Sonic and Shadow both ran up towards Tails. "I finally found you, bro. Come on. This is no time to stand around," Sonic urged. "We've got to keep moving.

Tails finally snapped out of his daydreaming. "Sorry Sonic," Tails said. "I'm coming." The vulpine joined the hedgehogs and the three of them continued their assault.

"Sonic, we have to get inside the city right away," Shadow insisted. "If we stick around here too long, we'll run into more of those things."

Tails shuddered at the thought of what Shadow was referring to. The undead were not creatures he was very fond of encountering.

"Too late, Shadow. They're already coming," Sonic said as he pointed to a band of zombies shuffling towards them. Their unnatural moaning was muffled by the sound of the rain pouring down.

"Just remember to slice them apart as much as you can," Tails reminded his friends. He pulled out the weapon that he hid inside his trench coat. It was a katana in a black sheath. The fox unsheathed the blade slowly, He could've taken it out instantly and attacked the zombies in one quick motion, but he wanted to save his energy and zombies moved slowly anyway. The sword gleamed a bluish silvery glow in the moonlight. He readied his weapon in front of him. It was the barrier between him and the monsters. One zombie lurched forward and swung a skeletal arm at the vulpine. He swung his sword in turn and cut the arm off. The katana tore through the rotted flesh and bone as if it were paper. Sometimes, Tails would joke to himself that his sword was better at cutting things than a lightsaber. It was magical, after all. The zombie didn't pay attention to the fact that it was missing an arm. Neither did it seem at all impressed at the weapon that Tails had brought against them. They didn't have the minds to do so. It made sure that they would still attack, no matter what. And attacked they did. Tails swung his sword again multiple times, causing the zombie to fall apart into tiny pieces. The fox moved on to another zombie before the pieces of the previous one had a chance to fall onto the ground. The sword was the same size as his own body, but it felt weightless in his hands. The nimble fox easily cleaved a path through them all. He saw that his hedgehog comrades were doing the same, just as easily. The ringing sound of the blade flying through the air was something he found to be very enjoyable. Almost soothing. Cutting apart the zombies was a cakewalk, really. The hardest part was always the smell and the guts flying all about.

"That's looks like all of them," Sonic said as he sliced a zombie into two equal halves down the middle with his own sword. "This sword works so well. Who would've thought Tails could forge magic swords?" The hedgehog lowered his blade and turned to Shadow. "Can you see anything through this haze?"

"Yeah. Eggman Empire, dead ahead," answered the black hedgehog.

"Wait. What's that sound?" Tails asked. He didn't really need to ask because he knew the sound all too well. It was the whir of machinery. The stomping of robotic legs. "Sounds like a big mech."

The robot had a vaguely humanoid shape and was twelve feet tall. It looked like it weighed a ton. Spikes jutted were protruding from nearly every part of its body. It raised up its two massive fists and slammed them into the ground. The slam sent a shockwave that knocked Sonic, Shadow, and Tails off their feet. Skulls on the ground shattered into white powder.

"I'll take care of this," Sonic said as he stood up, baring his longsword. He curled into a ball and did a sonic spin. Combined with his sword, it was a deadly move. He spun towards the robots chest. The spot with the least amount of spikes. He struck with his sword dead on, but bounced off, not making a single dent in the robot's hide.

"The Hell?" Sonic exclaimed.

"It's made out of adamantium, "Shadow said."We can't penetrate that. Chaos spear should be able to-"

"No. Wait," Tails interrupted. "I've got this." He walked up to the mech and extended one arm. The robots glowing red eyes analyzed the little mobian standing before him.

"Observation: Mobian, fox. Two tails due to mutation," said the robot. "Analyzing intent: Hostile. Proceed to atomize." The mech began to charge up the lasers mounted to its arm gauntlets.

"Heh," the vulpine laughed. "I've got my own energy attacks. Finally, all this lightning will be useful, for a change." Tails extended his arm toward the heavens and made a motion as if he were pulling something out of the sky. A lightning bolt descended and blasted into the robot where it stood. Tails extended another arm and made a fist with his hand. Now he was keeping the lightning bolt in place, so it would continue to pour its white hot energy into the mech.

"Assessment: Lethal electrostatic discharge. 85 percent damage to hardware." the robot said. The lightning dissipated, but not before melting the laser gauntlets to slag, as well as melting the majority of its spikes and its hard adamantium shell. The vulpine's powerful nose picked up the smell of ozone in the air.

"That should soften him up for you guys," Tails said to his teammates.

"All right, Tails!" Sonic said. "Now let's do it to it." The three charged at the robot with swords in hand. This time, they easily cut through the metallic mech. The robot blew apart, sending shards of metal and oil in all directions.

Tails looked down at his katana. Even with the rain washing the blade clean, it still dripped with blood and oil.

"Look, Tails," Shadow said. "We've reached the city gates."

Tails looked, but he didn't pay much attention to the iron gates before him. He was looking up, staring at the tall technological spires that towered into the sky. The city was full of them.

"You sure you're ready for this, buddy?" Sonic asked as he put his arm on his friend's shoulder."

"Ready as I'll ever be," Tails said as he returned the katana back to its sheath. "I can't wait any longer."

Lightning bolts were constantly striking the tips of the towers. Tails fixed gaze on the tallest one he could see.

"Cosmo is in here. And I'm going to save her."
