So let’s say that in a world where are the death note doesn’t an exist and Light Yagami is granted the power of the ghost rider, what would happen, how would things change and how would it affect the timeline because of him being the ghost rider.

What is better: fullmetal alchemist the manga, or fullmetal alchemist the anime. (I know there’s 2 anime, I’m talking about Brotherhood) sorry if this is a stupid question I’m new to anime/manga.
