In Their Own Image

"Yes... I, Grodus, will build a new world! A perfect, ideal world, made by me, about me, and FOR me!"

- Grodus, Paper Mario: The Thousand-Year Door

So things aren't going to well for you. Maybe you want to turn over a new leaf. Maybe you want to start your life anew. Instead, maybe you don't want to half-ass it, you want make all life anew. Or, you could just be a Card-Carrying Villain. This trope is when a character gets the bright idea to go back to the beginning of time, or a foundational event in the timeline, because their mere presence or actions will cause For Want of a Nail to its logical extreme.
