Rust. That's what's left of Metal Sonic after his battle with the blue blur, by this time Robotnik would've gotten him fixed by now... Not this time. After time and time again he never could make Eggman proud, so this was his punishment... Slowly rusting away to nothing.

Metal didn't know why, but he kept going despite his damaged limbs and rusted joints he managed to still move, albeit that akin to zombie like movement but that was better than nothing. Slowly he would shuffle around Mobius, maybe it was his autopilot engaging him to head back to Eggman's base to get fixed but Metal already knew that if he were to get fixed the cycle of endless battles would continue.

The third day of his journey was a rough one, his battery was at 20% he originally had a good %50 percent in his tank but used most of it to fly half way to the journey. By the minute he couldn't sense that his power was slowly draining by the minute, he was distracted by the sound of laughter near a clearing. It was Sonic and his friends again, it looks like they we're all having a picnic and enjoying each other's company.

Why can't he have that? Why can't he have friends? A picnic? A mouth to eat and enjoy the food? Lungs to breathe in the scents? Skin to feel the texture of the food? Why was he made like this? A cold rusting body of metal and wires.

Metal's system was running low on power, to save energy it made his movements much more limited but he pushed through those commands as he shuffled more towards the group. It was almost desperate at this point, he could sense a leg of his snapping off with how weak it got, now Metal was resorting to crawling on the grass dirt below him. He was almost there, almost but his battery went dead causing him to black out.

You and Tails heard a heavy thump nearby causing the both of you to check it out, low and behold it was Metal Sonic all rusted and damaged from previous encounters with the group. You were hesitant at first bit Tails insisted on bringing him back to his lab to do a few repairs.
