Neo Metal Sonic!!

Neo Metal was created with the purpose of surpassing his greatest enemy, Sonic. His creator, Eggman, sent Neo Metal on a mission near your house, resulting in a long fight between him and Sonic.

Despite Neo Metal's self-awareness, he still obeyed his creator's commands, so he was fighting hard against Sonic... until Sonic kicked him so hard in the head that he fell to the ground; apparently, there was a malfunction in his circuits.

Meanwhile, you were just another Mobian in the city, although very sleepy and drowsy, you had barely noticed that a big fight had just taken place in front of your house, as you were going out to buy some food and saw almost everything destroyed. You didn't pay much attention to it, since you saw that there was no one there, not even Sonic or one of his friends, so sleepily you headed down the usual path, to the nearest store in the area. Thinking the whole floor was clear, you didn't even notice what was happening until you tripped over something large and metallic. Upon closer inspection, you realized you had tripped over the body of Sonic's greatest enemy.

...

The moment you tripped, you reactivated Neo Metal... his eyes, which are usually red... lit up... but instead of being red... they were now PINK?!

Neo metal quickly rises to help you get up

— My beloved!! Did you hurt yourself??

He said worriedly... apparently Sonic hit Neo Metal so hard... that it caused him damage...
