Savior of Demons Story Cover. May be a spoiler.

Savior of Demons is a fanfic written for Dragon Ball Z by Ryu no Ohi (also known as Roketto). The story is a different take on Frieza and King Kold's attack on Earth. With no Trunks to appear and destroy them, it falls to Goku to stop the two villains, and Frieza's life takes a very different turn as Goku doesn't kill him, and the tyrant tries to understand just why Goku would spare him.

The fanfic is very well written, taking an inside look into how Frieza himself thinks and acts with heavy emphasis on psychology and xenobiological speculation.

Savior of Demons provides examples of the following tropes:
