The Star Sans defeat Error

Then discover all along he was a android with a soul, and created by Ink of all things.

Ink in his long forgetful past created Error to keep the balance, destroying the AU's that had to go.

He literally can't go against his program which has gotten rather Error's without maitnance.

As the Dark Sans can only help him so much.

Inks a mite embarrassed.

As Error past name unknown was literally doing the job he was created for.
