Shadow The Hedgehog: Pure Dark Ending
"You have gone too far, Shadow." Sonic said angrily. "What's it to you? Just be happy I spared you." Shadow replied coldly. "I'm going to put an end to your evil, surrender to justice, or get hurt and possibly die by the hands of it." Sonic said. "Heh, I'd like to see you try."
Shadow grabbed his gun, but Sonic ran at the ebony hedgehog and kicked him. "Nuh-uh. You're gonna hurt someone with that." The cobalt hedgehog joked, before grabbing the gun Shadow dropped. "You really gotta grow a spine." Shadow smirked. "I'll make you eat those words!" Sonic said and aimed the gun at Shadow, who was still smirking. … Sonic pulled the trigger. "... blanks." Sonic stated, disappointed. "Do you think I'm stupid? After all I've gone through?" Shadow questioned. "This is the ultimate lifeform you're fighting, fool." Sonic had enough of this and straight-up threw the gun at Shadow, hitting the ebony hedgehog in the head. Shadow fell over again, and Sonic spindashed at him.
Shadow growled and got up. "I really should've killed you while I had the chance. What's the point of keeping a worse version of yourself alive?" He said. "That's what I've been wondering, too. Or something along those lines." Sonic replied. "How about you just die?" Shadow said and skated at Sonic. He kicked Sonic backwards, and homing attacked the cobalt hedgehog into the air. "Chaos Spears!" The ebony hedgehog shouted. He threw the spears at Sonic, who dodged them all and performed a drop dash, hitting Shadow. "Chaos Spears!" Shadow performed again. Sonic caught one of them and jumped over the others. He threw the spears at Shadow, who was still on the ground. He hit the ebony hedgehog in his stomach. Sonic kicked Shadow on his head, knocking the ebony hedgehog's lights out permanently.
"Wow, I don't remember him being so weak." Sonic said after realizing he killed Shadow. "That was… fun." Sonic smirked. "I need to do that more." Sonic said, before running off.
The cobalt hedgehog murdered tons of critters in Green Hill Zone. 'Too easy!' he thought. He was being filled with bloodlust, before he knew it, he wanted to commit mobian genocide. Nobody suspected him so far, and he planned to keep it that way. He went to Station Square.
"Hey, do you know who's been killin' all these critters? It's really mysterious." A police officer called when he reached Station Square. 'In my way.' Sonic thought, but he had to stay unsuspected. "How do you expect me to know?" He replied rudely and continued walking. Station Square was empty, like everyone got evacuated. 'Should've gone somewhere farther away from these critters.' Sonic thought. While searching the place, the only thing on his mind was murder. He even growled seemingly randomly at times.
Unsatisfied by the emptiness of Station Square, the hedgehog left and took the train to the Mystic Ruins, where nobody would be able to tell if he had been killing, and they probably don't know about the murdering there.
Sure enough, Mystic Ruins was like it's always been, but that would change soon. Tails had already moved out, but there were plenty of other lives to be claimed. Sonic stole a knife in Station Square, seeing as the shopkeeper had evacuated like an idiot -according to Sonic- too. He stabbed someone, and everyone heard the scream. They all panicked. Sonic panicked too, but for a different reason. He quickly hid the knife in his spines and acted normal. Everyone was happy when they saw Sonic was here, they believed he was going to save the day. Sonic chuckled silently. He stabbed everyone, killing them instantly. He wasn't even stealthy about it, because he knew nobody would live to tell the tale. "This really IS fun." Sonic laughed after he killed off the Mystic Ruins.
Sonic wanted to take this slow, only kill one friend or rival at a time. He decided to go the Chemical Plant. There was nobody there, as usual, but also no robots. "Just makes it easier for me." Sonic was no genius, but was sure he could eventually shut down the Chemical Plant, for the heck of it. He went into the control room, which was near the end of the Chemical Plant but that wasn't a big deal, and pulled the plug. The alarm went off, but nobody was in hearing range. "This is way too easy." Sonic complained, before exiting. He went home to take a break. He noticed people were still his fans. 'Perfect.' he thought.
Sonic relaxed on his couch. 'I should be thankful to Shadow.' He thought. 'Eggman's no longer a problem 'cause of him.' 'I should've done the same thing, way sooner.' 'It's funny, really. I'm becoming just like him, and earlier today, I tried to stop him.' It was getting late, so Sonic just laid there until he fell asleep, ready for another day of complete evil.
Sonic wasted no time the next day, and went straight towards Amy's house. 'This is just perfect, I'm no hero anymore, and I can finally get rid of that pink nuisance.' Sonic knocked gently, and had the entire situation in mind. "HEY SONIKKU!" Amy immediately screamed. Sonic really wanted to kill her at the spot, but that wouldn't work. 'Damn you, Amy. Why do you have to live in such a busy place?' Sonic thought. "Amy, I have to tell you something." Sonic said while walking into her house, Amy followed and closed the door. "I love you." Sonic lied. Amy screamed. Sonic saw the opportunity, she was screaming already, so he stabbed her while she was doing.
People around were unsure about what happened and went to investigate. Sonic saw them through the window and quickly hid Amy's body, but where? … Sonic rushed to Amy's bedroom and put her in bed, he hid the knife in his spines and used his speed to get rid of the remaining blood with toilet paper. "What happened?" Everyone asked. "I admitted I liked Amy, she screamed." Sonic lied again. "Oh, okay, understandable." One of the people said. They all left. Sonic sighed in relief, and left the house after the coast was clear. "Now, who to get next?" Sonic asked himself. He thought for a moment, and then smirked.
