Chapter 1: A Hero's Quest

"Whooooooooooooooooooooooooooaaaaaaaaaaaaaaaa" A blue anthropomorphic hedgehog was falling down from the sky, screaming as he fell. But as he fell, he eventually regained his position and landed feet first onto a city sidewalk. Luckily, he was unharmed. But the fact that he just landed inside a city which he didn't know, was rather strange to him. Strange, yet calming. Who was he? He is Sonic the Hedgehog. A world-renown hero to his home planet of Mobius and of the planet Earth. He is the world's fastest being, and if you want to know how fast? Picture something going at the speed of sound. A jet, a rocket maybe. Now picture something going even faster. That's Sonic for you. He looked around the sidewalk and saw a bunch more anthropomorphic animals like him walk into a large amphitheater. Some stared at him, others (not wanting to be rude) ignored him and proceeded into the large theater. How did our hero get into this city? Well, let's start a few minutes earlier.

FLASHBACK

MOBIUS, 12:30 P.M., RADICAL HIGHWAY

Sonic was running faster than the speed of sound to try to get to the TechnoDrome bank. Radical Highway connected to a very popular part of Mobius called Central City. After successfully running through the immense traffic leading out of the city, he jumped up towards a really high skyscraper, performed several lightning-fast somersaults in the air and landed, then parked his red sneakers on the building, then did the somersaults again. This was a signature move of Sonic's called the Spin Dash. Once he finally reached the top of the building, he could finally see the TechnoDrome. It was a huge dome shaped building built on top of four steel pillars. After observing that the lights on, Sonic immediately recognized the shadow of an unmistakable nemesis robbing and pilfering the bank. "Eggman again?!" Sonic said in dismay, "Well, at least he gave me something to do tonight. As if it's really going to be a tough challenge though." the confident hedgehog said, as he sped off towards the bank. As he effortlessly ran and leapt over the roofs of several apartments, he finally Spin Dashed his way into the bank, accidentally breaking a window. Sonic looked at the busted window, sighed, and said "Oh man, I'm going to be in some trouble for this." He then heard loud mechanical footsteps approach from behind him. "But not as much trouble as you're gonna be in for robbing the bank Egghead!" he shouted as he confidently turned to face his lifelong nemesis. Dr. Eggman, a tall, somewhat chubby man with a brown zigzaged mustache on his evil face, was inside a giant frog-like robot inside the bank. It was almost an exact replica of a red-eyed tree frog. If tree-frogs were gigantic, made of metal, and had computers inside of it. The "Dr." part of his name isn't a moniker or a nickname. No, this evil genius actually earned that title after his first fight with Sonic. Since then, the pair have fought countless times, but no matter how slim the margin or how seeming the defeat, Sonic always found a way to destroy whatever evil plot his enemy had for him, and His World. "Oh come on Sonic. Admit it, this is my greatest invention yet. And also, you can be sure that this plan will indeed work this time." "And it will work...how...exactly?" Sonic taunted. "You know, I could waste my time by telling you, but I need to 'hop to it' to steal everyone's money and leave everyone no choice but to be my slaves to earn it back." Eggman rebutted. Sonic not only knew how to physically win a battle, but had plenty of ways to mentally win a battle as well. "I thought you weren't going to waste my time." Sonic responded, as he jumped, spin-dashed into the robotic frogs LED red right eye and busted the lights on it. Sonic then started running around the bank as Eggman's Frog-Bot started leaping towards him covering immense space. The frog was also firing missiles at him from its mouth, but they seemed a little off target. Especially for Sonic, who successfully dodged missiles like this before even when they were on target. "You know Eggman, you should stop making things too easy for me." He spin-dashed the Frog-Bot's other eye out and landed on top of the giant robot. The Frog-Bot then was about to jump out the window, but not before Sonic quickly jumped off the robot as it leapt out the same window Sonic previously busted. As it was starting its descent, Sonic jumped out the window and was looking for an opening in the bot. He finally found one in the mouth, so he spin-dashed towards it, lifted it up, and ran through it to find Dr. Eggman attempting to activate an escape pod. Sonic smirked, then ran to the doctor. "Come on, escape pods, that's no fun" Sonic said as he grabbed Eggman's wrist, ran him out of the opening and effortlessly flipped the doctor into a police chopper. "Take it like an Eggman and don't crack." Sonic said as he smirked, winked towards the frusterated grimace of his enemy, and leapt off the plane, placed his feet along the side of a skyscraper, ran down it, then stopped on the road. Millions of people and animals all gathered around the hero as if he were a movie star and were cheering him for his efforts. Sonic simply smiled, spun 360, stuck a finger from his left hand, and waved that hand. Some anthropomorphic animals present actually did go as far to take pictures as the crowd was wildly cheering "So-nic, So-nic, So-nic…"

FLASHBACK ENDS

PRESENT DAY

Our hero now curiously looked at the line of animals before him, so he ran to a ticket booth to find out what's going on. "Hey look buddy, can't you see that you need a ticket to get in." A rhino grumpily informed Sonic. Sonic then looked down at the sign that said "Tickets: $5" he looked at the guard and said, "Look buddy, I'm not from around here. I just want to see what the line was for." The rhino, seemingly more friendly-looking now, understood that this blue hedgehog was an outsider. "Well, if that's all you want to know; there's a big Gazelle concert going on tonight if you want to get in, but you still need to pay the $5 buddy." Sonic now knew that the ticket-taker was a friendly guy who didn't see many outsiders. He also correctly assume that Gazelle was a famous singer. Sonic looked, and then realized he didn't bring any money on his trip. He then frowned defeatedly and started to walk away, when all of the sudden, a black panther strode up and tapped Sonic on the shoulder. "Hey listen buddy, you forgot to bring money?" Sonic didn't want to bring any attention to himself, especially since the rest of this new land hadn't heard about him. "Yeah, I did." Sonic lied. "Well, I'll tell you what, I have an extra 5 right here. How about you pay that to the guy and have a good time." the panther smiled and said. Sonic didn't want to take the panther's money, although he did think it was very generous of him. "Look, I'll find a way to pay you back…" "It's no trouble really" the panther replied, as he paid the 10 bucks to the rhino. "You're paying for him Manchas?" the rhino asked. Manchas just nodded and Sonic stood amazed at how quickly he found generosity in a stranger. "Well, here's your ticket. Find the Section and Seat Number and you'll be fine." the rhino said, as he flashed him a smile. Sonic then thanked Manchas, flashed the rhino a return smile and ran to look for his seat.

Ok guys, that's the first chapter, like I said, I don't know how often I'll be updating because of studies and life, but I hope you'll all like it. Next chapter: Sonic sits down, enjoys a show, and meets 3 Zootopian legends in one night. Also, how did Sonic actually get here in the first place after beating Eggman? Find all that out next time. See you then.
