That was his goal, his objective.
The universe couldn't handle two Sonics, and he believed that. It's impossible, reality will crash...so he must.
But something was always off. Metal Sonic was superior, far better than Sonic could ever be. Then...why off all things he couldn't...defeat...Sonic the hedgehog...
Impossible, negative. There was something wrong, a reason as to why Sonic couldn't be ridden of. Unless...
There's the thought again, the same one that always comes after a defeat. The one that defied and questioned everything.
If he was the real Sonic, then why was he artificial? Why is Sonic able to breathe? Feel? Metal Sonic knew the answer, it made perfect sense it always does...he just couldn't handle the truth. It goes against everything, his entire existence, as to why was he...like this...
Metal Sonic looked down at himself, although dented and scratched and well...trapped under some rubble with barely any power to get out. Having ran a diagnosis, it confirmed that the damage to his systems was moderate. If he wasn't already distracted by his irrational thinking, Metal Sonic would of won.
