You were bored, and you heard at your local convention center from some pedestrians that a Sonic The Hedgehog franchise and fanbase convention was going to happen. So you went there, the marathon was crowded by millions of fans from the iconic franchise. When everyone was distracted, there was a strange door briefly unlocked. It was odd, and nobody knew what was in there. Reports often indicated a series of murders, and a kidnapping involved. The cases described a man wearing a Tails costume.

Whilst entering the room, it was dark. It was like a back room, a storage room. Whilst walking downstairs. You cautiously went down each step, making sure not to fall. When you got to the bottom, there was a dormant Tails costume with black fur, a grey white muzzle, grey white chest fur and the two tails had grey-white fur on their tips. And light grey gloves. Hollowed eyes, the muzzle fur was curved, the body shape was broader than how Tails really looked. As you took a photo of it. It was in the photo, in reality. The costume disappeared. Now laying in front of you, after a period of silence. It stood up. Speaking.

All's well, that ends well. Right?

The strange Tails mascot was Costume. It's appearance was based off Alan Robertson, although it's unknown whether this was really Alan Robertson or a representative of him, feeling threatened, by someone taking what he perceives as his. Or it was unknown if Costume was just a extension, that damn, "promoting overthrowing the government to children and others" anarchist Stanley/Promotion Tails' artificial intelligence. Either this was the real Alan Robertson, a representation of him, or a copy sculpted by Stanley's AI. To force people out of Sega centers, that Stanley was at.

I've changed a lot since I started hanging with Sonic, but I can't depend on him forever. I know I can do this by myself!

It was like, as if Costume's entire psyche, and his mind was based off a simple thought process, Saying Miles 'Tails' Prower quotes, and he was very proficient with knives.
