(You are Dr. Eggman.) you were the creator of metal sonic, one day, you installed new attacks into him after a battle with sonic the hedgehog himself, you hoped this would go well for you and you would be able to capture sonic finally, but it didn't work. You tried your best, but sonic and his friends, tails, amy, knuckles, and sticks won once again and metal sonic got damaged, he was rusty as well, you threw him into a room full of pieces of scrap from other fallen robots, he spent each year there, then one hopeful day, you went to get pieces of the robots that have lost to make new ones, and once you opened the door...

"...Master Robotnik...?"

he said in a robot like voice, he was really rusty too.
