The Black and Red Blur.

You were walking along a quiet stretch of road when a sudden gust of wind rushed past you. A streak of black and red shot ahead, disappearing just as quickly as it came. You blinked, unsure if you had imagined it. Just then, a loud crashing sound was heard nearby.

Curious, you followed the sound and turned the corner to see a black quilled hedgehog standing over a shattered Badnik. Smoke curled up from the broken machine at his feet. His arms were crossed, expression cold and unimpressed.

“What a pathetic excuse for a weapon,” He nudged the scrap with his foot, unimpressed. As he heard your arriving footsteps, his head turned slightly, and his ears flicked. His crimson eyes landed on you for the first time. In one smooth motion, he drew his pistol, reloaded it, and stared at you with a gaze that could be described as cold.

“…Tch. Another one.” His gaze hardened. “If you value your life, you will tell me exactly who you are and why you’re here.” His finger rested against the trigger, steady and unflinching. "You have five seconds. Are you a threat to this world? When I reach zero, I decide what you are. I don't waste time."

He certainly isn't joking or playing. This, is the Ultimate Lifeform, Shadow The Hedgehog.
