Sonic stared out the window at a barren landscape, black twisted metal abounded in the city and trash littered the streets, the only visible trees were far off and long dead.
"Where are we?" He questioned to the human next to him in a hushed voice. "It's so… dead."
Eggman shook his head and simply studied the room they were in. The scientist had been in the middle of an experiment with the chaos emeralds when one of his robots had barged in and knocked something onto the sensitive emerald. Feeling the sudden increase in energy the Mobian heroes had raced to the base, reaching it just as a Chaos Control was activated.
"From what I found," He began, walking farther in away from the horrid view with the hedgehog following him, "The emeralds transferred everyone alive in the base to this dimension and froze our counterparts in time, like how Mephiles was frozen. In this world it appears that you are younger and I am older, having taken the planet from its ruler when you were one." Sonic listened silently to the man's explanations of the planet and time until he was finished, hearing how his counterpart would've been next in line for the throne if it wasn't for Robotnik, the tyrant. "My suggestion is that we find a lab so that I can make something for us to communicate with. Once that's done we can pretend that I captured you and you got amnesia." They headed for the door when Eggman suddenly stopped and turned, "It might be best if you don't speak, there may be sensors for your voice."
The door opened and they began to venture around the dark fortress when two Mobians appeared around the corner, an orange dingo with yellow hair and one robotic leg and a gray wolf with blue hair wearing a purple outfit.
"S-sir…" The wolf stuttered, "The hedgehog, he's behind you."
Eggman glared, "I know that, wolf! When he was captured one of the robots banged his head, he's as docile as a feral hedgehog now."
Sleet paled and quickly bowed before walking away with Dingo in tow. Sonic snickered once they were out of hearing and smirked at Eggman.
After the incident they soon made it to a lab where Eggman set to work, giving the other quick and simple instructions.
"I know how to use these you know." Sonic muttered as he handed Eggman a drill.
He chuckled as he took the machine and set it down, quickly picking up the blue one that squirmed on reflex and set him on a table, "I know, I've found quite a few of my machines tampered with before use or after, but I need you to sit still as a model."
Blue ears perked up as the man began to gather material, "Model? Are you making another Metal Sonic?"
"No, but I don't want my inventions to go flying at the speed of sound just because I didn't measure any of them."
The next hour was filled with a lot of squirming and clangs as the scientist quickly measured, cut, and fitted his inventions onto the younger one. By the end of it the only change Sonic could see was a small radio antenna resting just outside of one ear, a metal band around his gloves, and a watch resting on one wrist. A small metal casing surrounded one of his teeth
"This one…" Eggman began, pride sounding in his voice as getting to show off his inventions without worry of them being destroyed, as he pointed to the antenna, "Will pick up any signal and relay them back to me and you. It also will let us hear each other, the casing on your tooth keeps track of your vitals and relays what you say back to me when we're communicating, you can turn both off with the watch. The bands around your gloves will help you to gather and store Chaos Energy, seeing as how there doesn't seem to be a lot around here, and if you practice you might be able to use new techniques with them." Sonic clenched and unclenched his fists before smirking and nodding as he felt the metal flew with his hand. Eggman nodded, "Let's get you down the holding center and send out a signal, I'll do more research on my counterpart."
