Here I have listed what I consider the best fanfics on the internet. Right now most are Dragonball Z fics.
Crono's Story
A great fanfic set 100 years after DBZ.
Dominion Reprise
It is hard to summarize this fanfic but it is one of the few fics out there deserving to be published.
Orion Saga
Staring a boy named Orion, this story is extremely well written and its characters are some of the best original characters created for any fic. Also, it is drawn in Fanmanga.
Twist of Fate
A very good story that takes place a little while after DBZ and has a great plot.
Dark Ki
One of the most popular fanfics on the internet, this story written by Ridureyu is based on what would happen if Frieza was never born.
