No. I do have a story and I'm halfway through finishing the script for the first saga, but you know I'm that key part of a visual novel. You know, the visual part. But if it is really so important that every last detail of the project is then I'll oblige. The story will follow a descendant of the Frieza family in the age 850. After being defeated by Goku several times, Frieza eventually loses his empire as people no longer respect his rule. The main character, Pola (may change the name) steals a time machine from the time patrol. He goes back in time to just before Raditz arrives on Earth, where he mortally wounds himself before switching bodies with Goku. Goku dies in the body and Pola take his place. He then fights and defeats Raditz with the help of Piccolo. Pola had vowed revenge on Goku and his friends, but rather than destroying them he decides to make corrupt them (i.e try to make them evil). Some of course will be harder than others, e.g.(Vegeta will be easier than Krillin) and will take time. The training part comes in when dealing with the women (Chichi, Bulma, Android 18 and a few others). I hope this has satisfied anyone's questions, queries or qualms.
